Literature Review: 1.1

INTRODUCTION:

“Convention is the name given to a general or formal meeting of a legislative body, social or economical group in order to provide information on a particular economic situation and in order to deliberate and consequently, establish consent on policies among the participants, usually of limited duration with set objectives but no determined frequency.” -Lawson Fred, Congress, Convention and Exhibition facilities: planning design and Management (Architectural press: London, page 9) The term Convention is widely used in much discipline. A ‘Convention’ word in general can be defined as o A large formal assembly of a group with common interests, such as a political party or trade union o The persons attending such an assembly o (U.S. politics) an assembly of delegates of one party to select candidates for office o (Diplomacy) an international agreement second only to a treaty in formality o A telecommunications convention o Any agreement, compact, or contract o The most widely accepted or established view of what is thought to be proper behavior, good taste etc. Convention – A large meeting of member of profession, a political party, etc. Center- A place or an area where a lot of people live, a place where a lot of business and cultural activity takes place Oxford Advanced Learner’s Dictionary 7th edition, Oxford University Press A convention is not simply a space for looking at or listening to a performance. A successful convention for live performance supports the emotional exchange between the performer and the audience, and between members of audience. Thus conventions are usually general sessions, mostly information giving, often formed around a particular theme or subject matter of topic interest and increasingly accompanied by exhibits. In addition to need for large halls & auditoriums required for the plenary sessions, most conventions break down into smaller groups to deliberate on particular matter of issue. Convention CenterA large civic building or group of buildings designed for conventions, industrial shows, and the like, having large unobstructed exhibit areas and often including conference rooms, hotel accommodations, restaurants, and other facilities. (www.dictionary.reference.com) A convention center is generally defined as any property used in connection with a convention or meeting center, or similar facility, including auditoriums, exhibition halls, facilities for food preparation and serving, parking facilities, and administrative offices. A number of states have passed legislation enabling public funding to be used for convention centers in an effort to attract tourism and businesses to the local economy.

Convention Center Design Studio VI 1.2 COMPONENTS OF THE PROJECT: Exhibition Spaces: In its broadest sense, an exhibition is a display, show or demonstration of something of beauty, value or particular interest to a targeted audience. Exhibition halls should have the space, freedom and flexibility to create an exhibition environment. In any exhibition halls, proper considerations should be given to the movement of people and also to the moving pattern. On the other hand, outdoor exhibition spaces are usually located to immediate vicinity of the exhibition halls. Outdoor exhibition areas can be developed as a flat ground or as an amphitheater. Conference Spaces or Auditorium Halls: Conference halls or Auditoriums are mainly allocated in the exhibition spaces to hold conferences and/or seminar during the exhibition period. Proper attention must be provided in designing entry and exit routes. Multipurpose Halls: Multipurpose Halls can be used for conferences, exhibitions, meetings, symposiums and several other events. Multipurpose Halls can also be used as Banquet and/or Event Halls and sometimes also as Galleries. Other Important spaces of a Convention Center include:  Recreational Spaces.  Gallery.  Restaurants.  Administrative Spaces.  Parking Spaces.  Landscaped Areas. 1.3

MAJOR DESIGN CONSIDERATIONS:

1) Access and Entrance:  Separate access is required for visitors, staff, goods and service vehicles and emergency requirements. It is usually desirable to provide alternative entry for public which is independent from that used by conference visitors. This not only facilitates management and security, but also enables two or congress events or exhibitions to be run independently in parallel.  Easily identifiable entrance and exit, and clear external signage, which may need to be illuminated.  Sufficient unloading/loading space to accommodate multiple events.  Level ground floor with loading docks of sufficient size for all services including client vehicles.  Large coach drops off and collection points adjacent to main entrance, with sufficient turning space and height, accessible under cover.  Doors of sufficient width and height or demountable/retractable walls to permit truck access (trucks delivering exhibit and staging equipment pose particular problems).  Floor loadings to permit truck access.  Easily identifiable and weather protected entrance and reception area for attendees.  Clearly identified disabled access.  In larger venues, security systems and monitoring at loading docks.  Separate entry for venue staff. Pukar Bhandari (070/BAE/225)

Convention Center Design Studio VI  Storage space (for several days) for pre-congress consignments including exhibitors’ displays materials.

2) Access for the disabled:  Specific provisions include allocation of parking spaces, identification of routes, provision of ramps, toilets and facilities designed for wheelchair and other disabled users in each main area. 3) Parking:  Coach parking bays off street.  Sufficient undercover parking for attendees.  All parking, including venue staff parking, should be secure.  Direct access to venue lobby.  Clear directions for exiting car park.  Parking requirements for cars and other vehicles will depend on some extent on the proximity and conditions for use of alternative facilities, such as municipal car parks, as well as on the availability of public transport. Typical provisions to allow flexibility in use are: Use Per Car Parking Space Banquet Places 10 Sq. m. Congress Hall Places 10 Sq. m. 4) Service Vehicles:  Plenty of space for parking while unloading/loading goods and equipment with a dedicated car park for vehicles delivering goods or equipment.  Parking for trucks with sufficient height and turning space where staging, audio visual or other equipment needs to be packed in or out within short period of time.  Long-term parking for trucks used for transporting production equipment and exhibitors’ displays. 5) Horizontal and Vertical Arrangements:  The single floor organization provides easy access among the rooms and between the conference areas and other functional elements. This plan imposes few structural or mechanical constraints, permits total freedom in the planning of the rooms, allows for access from the refreshment break areas to outdoor terraces and patios.  Vertical stacking of auditoria and/or main halls is more economical in the use of land, and enables space below tiered floors to be more efficiently used. Unit costs of construction are higher and vertical transportation of people and goods may present difficulties. 6) Circulation:  Linear arrangement of spaces with beginning, middle and end.  A loop where the essentially linear storyline leads naturally back to the beginning.  An arrangement of core and satellites where each theme or detailed treatment of a subject leads back to a central introductory or orientational areas.  A more complex scheme combining linear, loop and core-satellite arrangement of spaces.

HISTORICAL BACKGROUND:

Convention centers and Exhibition spaces evolved from the open-air amphitheaters of the Greek Agoras and Roman Forums, which were initially intended for large commercial fair. The first convention centers can be traced back to mid-19th century Britain. Commonly known as exhibition halls, the centers were designed to bring together people to discuss and explore their mutual interest of a subject. These imposing Victorian buildings often covered several acres and were multi-functional incorporating lecture halls, libraries, galleries, theatres and exhibition areas. The Crystal Palace, Hyde Park-

Pukar Bhandari (070/BAE/225)

Convention Center Design Studio VI Among the first historical convention centers constructed was The Crystal Palace in London’s Hyde Park. Providing 92,000 m2 of exhibition space, the building was erected in 1851 to house The Great Exhibition a grand show case of modern industrial technology and design. Organized by Prince Albert and inventor Henry Cole, the Great Exhibition was an international platform for world powers to demonstrate their technological and cultural achievements. Although countries all around the world could contribute, British exhibits - from working machinery to scientific and surgical instruments - took center stage, promoting Britain’s position as a great industrial power. In 1854 the Crystal Palace was dismantled and re-built in Sydenham, an area of south London which by association became known as Crystal Palace. Ravaged by fire in 1936, the building was eventually pulled down. Bingley Hall, BirminghamAnother key convention center in Britain’s history is Bingley Hall, Birmingham. Constructed in 1850 from surplus steels used to build Euston Station, the exhibition hall boasted over an acre of exhibition space and was serviced by ten entrances. Bingley Hall was a primary meeting and exhibition space and before it succumbed to fire in 1984, hosted several key events, including cattle shows, concerts and boxing matches. It was also the center for British Prime Minister Gladstone’s political rally in November 1888. In Bingley Hall’s place now stands Birmingham’s International Convention Centre (ICC). Opened in 1991, the ICC is a major exhibition center comprising ten halls which can accommodate up to 8,000 visitors. The site also houses Symphony Hall, a 2,000 seat concert hall, alongside shops and cafes. Dedicated Conference CentersBorn out of the need for dedicated meeting spaces away from the traditional corporate environment, a new breed of meeting venue has emerged in the last few decades the purpose-built conference center. These multi-functional buildings are designed to maximize attendees’ productivity and concentration by offering a dedicated learning environment in high quality private surroundings. Facilities typically include self-contained conference buildings, break-out rooms, exhibition spaces, dedicated dining rooms and social areas. For added comfort and convenience, today’s purpose-built conference centers usually provide on-site overnight accommodation, leisure facilities and free parking. Lane End Conference Centre was one of the first purpose-built conference centers in the UK. It opened its doors in 1969 and today it boasts five distinct buildings each with a dedicated conference suite, lounge, bar, dining room and a number of dedicated bedrooms for residential events. CONVENTIONS IN NEPAL In our context, the Dabali, Squares, Chowk, etc. was used for the any public functions. Pati, Chautara in Village is even today used for the formal meeting. But these day people are slowly moving towards enclosed space. In present time, different functions like auditorium, conference, seminar, exhibition, library, gallery, etc. take place in certain space with different forms.

Convention Center Design Studio VI Convention industry is regarded as an essence of a tourism that makes huge profit. On the aspect of a nation, convention gives economic benefits and also promotes personal exchanges and cultural exchanges. It also gives a chance to get advanced technologies and latest information. Nepal stands popular as an international meeting destination in the world’s business community. Conference halls and top hotels provide excellent meeting facilities at par with international standards, while professional groups that include hotels and tour operators have eased the process of organizing and managing these events. The International Conference Center in Kathmandu is a state-of-the-art convention facility, consisting of numerous halls of different sizes with seating flexibility to cater to various needs. The largest hall can accommodate as many as 1,046 people. Convention centers apart, numerous standard conference facilities have been built into the luxury hotels in Kathmandu and Pokhara. Kathmandu’s connectivity to several cities of Asia and Europe by direct flight makes the mesmerizing capital, with its many attractions, an ideal MICE destination. This gateway to the Himalayan nation offers superb options for work and recreation to go together. Delegates from around the world can enjoy in Nepal a Himalayan holiday even while at work. MICE tourism is the new buzzword in international tourism market and relates to various forms of tourism business concerned with groups of business individuals rather than individual business travelers. MICE stand for: Meetings, Incentives, Conferences and Exhibitions. Nepal is a unique place for MICE tourism because of its natural beauty and extra activities that it has to offer. Meeting, Incentive, Conference and Events are being popular activities of tourism business in Nepal. The world class hotels and resorts are located in various touristic places around Kathmandu valley and Pokhara valley. You can have various options for hotels and location. Either you want to conduct the program in town or outside the town, you will get best venue in luxury hotel and resorts. While you do program outside the city, you will get an opportunity to enjoy with the beauty of nature that offers you extraordinary scenery and landscape. Nepal offers a vast range of hotels, convention centers and conference facilities, from small to big for a perfect selling. Katmandu offers a wide choice of conference centers. Besides the conference facilities at the five star hotels, there are alternatives. Birendra International Convention Center has state-of-the-art facilities for conferences and conventions with sophisticated audio, video, lighting, communications, catering, ventilation and parking facilities. Kathmandu has a number of international class hotels to suit every one’s fancies and finance. Soaltee Holiday Inn Crown Plaza, Hotel Yak & Yeti, Hotel Everest, Hotel Annapurna, Hotel Radisson, Hotel Hyatt, Hotel Shangri-La and Hotel Le Meridian are the five star hotels in Kathmandu. Outside Kathmandu, there are some finest hotels/resorts such as Godavari Village Resort in Godavari (approx. 20 km from Kathmandu) and The Fulbari (one of the finest hotels in South Asia) in Pokhara.   

History of MICE in Nepal: MICE is new paradigm of tourism in Nepal, started/highlighted since 1987 after 3rd SAARC summit. Highlighted after cabinet meeting of 2011 in Mt. Everest Base Camp Gradually spread all over Nepal

Lack of TSA, number of tourist arrival for MICE is not accounted but number of conventions are increasing Center of thriving Trans -Himalayan trade for merchants not only exchange goods but also ideas and philosophies Capital Kathmandu legacy as a meeting jaunt with international standard meeting facilities pre and post conference tours Best place for MICE specially travel trade, caucus great location, excellent infrastructure, comprehensive high tech convention facilities and expertise Conference, seminar or special incentive in different scenic splendors and unique blend of cultures in Mountain, Hills and Terai. Why MICE Tourism in Nepal. It is a peaceful and a safe destination. The Nepalese people, as diverse as they are, live in harmony – perhaps fatalistic, perhaps content, but they take on the hardship of life with a smile. Hinduism and Buddhism have co-existed so harmoniously in Nepal for centuries. It is a destination that will fire up the imagination of the delegates. They can have unique pre or post tour programs especially designed to suit the budget and their liking and interests. Cultural and Natural Heritage site, three antique royal cities Kathmandu, Patan and Bhaktapur with old Historical Monuments Different conference centers in Kathmandu city, Birendra International Conference Center(BICC) is a state-of-the-art convention facility, Rastriya Sabha Griha (City Hall), Nepal Academy Hall, National Theater and number of luxurious hotels with meeting halls.

Convention Center Design Studio VI OPEN-AIR EXHIBITION SPACE The landscape design shall be developed in keeping with the Theme and with the Participant’s approach to it. Like architecture, the landscape shall also help to tell intriguing stories about the pleasures of the table, delightful scents or strange and curious stories related to food cultivation and processing. The landscape has to document the most advanced research in the field of food production and the transformation of agricultural products. Countries will showcase their capabilities in food production, the biodiversity of their products, and their agricultural and food supply chains. Open spaces A minimum of 30% of each lot must be dedicated to open areas and greenery. Excluding lot setbacks the Open-air Exhibition Space represents around 50% of each lot, where it is possible to build:  

Structures used for plants ensuring soil permeability (e.g. trellises, pergolas, garden structures, planters). Landscaping structure (e.g. structures used to retain soil or other materials, pools, exhibition structures, art works).

COVERED EXHIBITION SPACE Covered Exhibition Spaces are buildings or enclosed structures containing exhibition areas or other spaces, including all overhanging upper floors or balconies. Participants may decide to build more than one level within the Covered part of the Exhibition Space, based on their individual needs. Height of Buildings • The height of the Covered part of Exhibition Space (or Building Height) must be less than 12 meters. • The height limit for any additional architectural elements (such as skylights, roof elements, vertical connections to the roof, sunscreens, signals, etc.) is 17 meters. Building Setbacks • The setback from the main boulevard must be no less than 10 meters, in order to create a small square. • The distance between buildings and the side street shall be no less than 2 meters; there shall be no building concession directly to squares, greens, streets or public spaces, without the 2 meters’ setback. • The setback from the neighboring lot shall be no less than 3 meters. • The distance between buildings shall comply with fire control requirements. Indoor exhibition and Flow management

Pukar Bhandari (070/BAE/225)

Convention Center Design Studio VI The indoor exhibition space design has to offer to visitors a full immersion in the Theme on the human scale with content presented at every moment of the visit. The visitor should be guided on a discovery of the exhibition content using the most innovative technology. The challenge lies in getting beyond the outdated paradigm of queues and visitor flows to create an efficient, dynamic and fluid experience.

Entrance/Exit - Queue Management In order to enhance visitor ease and reduce queuing, the Organizer will set up a virtual queuing system to improve Level of Service (LOS) by reducing waiting time and optimizing the waiting areas of other uses. Building entrances and exits shall be designed taking into account the surrounding conditions and landscaping requirements. 

Exhibition spaces may have multiple entrances/exits on different sides of the lot. They must provide differentiated access for visitors, including disabled, special reserved visitors, reserved groups, workers and finally supplies/waste.  If a main entrance for the Exhibition Space is planned, it cannot give onto the Decumanus. This side of the lot may only have exits. The queuing area must not occupy or overflow onto the Decumanus. Goods entrance and waste removal are planned during the event closing hours and could be done by using all pedestrian access except the Decumanus area. General guidelines for planning all sorts of exhibitions can be summed up as: 

Visitors should be correctly oriented inside the exhibition area.



Viewers should be able to move through the exhibit without being forced to walk past objects they have already seen.



Adequate space should be provided for visitors to move at different speeds. The circulation space should also allow the visitor to take a quick look at the exhibits so that they can decide which ones to examine in detail.



A viewer tends to turn clockwise upon entering the exhibit area. Circulation pattern should be designed with this in mind.

AUDITORIUM The auditorium is the heart of building, where the primary activity of experiencing and presenting performances take place. Audience seating is arranged to view the stage and the stage is a platform from which the performer can be communicate to the audience. The relationship between the two is very crucial for the success of convention centers. Mostly auditorium is designed to fulfill no of purposes. The objective of designer will be to use 100% usage of space. Auditorium should be designed in such a way that every member should be able to see and hear the performance of stage. Pukar Bhandari (070/BAE/225)

Convention Center Design Studio VI General Design Criteria of Auditorium 1. Form/shape Shape corrects the defects of sound in auditorium hall i.e. echo’s, excessive reverberation, sound foci’s, dead spots etc. fan shape <100 degree is ideally best shape for auditorium. In auditorium hall, the wall & ceiling is not perpendicular to each other as in other normal rooms. Mostly less curve Concave shape is also considered. The size of hall is governed by audience requirements, Visual & aural limitations.

Audience Requirements Every member of the audience should be able to see and hear clearly

Visual Limitations •

For drama= 20m

•

For Opera= 30m

•

For dance= 20m

•

For conference = 20m

Pukar Bhandari (070/BAE/225)

Convention Center Design Studio VI

Aural Limitations It refers to the distance across which speech, singing and music can be clearly heard without need of amplification. For amplified sound dead acoustic is required, which is impossible in auditorium. So, careful acoustical consideration is required for aural requirements. The Volume of unamplified sound depends upon Volume, Shape, Size, internal finishes of auditorium & Reverberation time. Size of Hall = min 0.6-0.9 m2/person

Volume of Hall= 4- 4.5 m3/ person

Seating Planning Seating planning in Auditoria help to spread music and it makes visibility clear. Acoustically, concentric arch seating is preferable to focus the audience view towards stage. The first row > 3.6m from the stage. The alternate seating plan can enhance the visibility. Mostly different size of seating (Size difference of 2”) is provided to maintain the alternating seating which is not noticed by patron. Seating Capacity         

minimum Dimension of seating with arms =500mm Without arms =450mm Seat height = 430-450 mm Angle of inclination= 7-9 degree with horizontal Back Height = 800-850mm Angle of inclination = 15-20 degree Seat Depth= 600-720 mm, reduced to 425-500mm when the seat is tipped Other Factors affecting seating is, Acoustics: Upholstery to satisfy the acoustic requirements, usually the level of absorbency when unoccupied Ventilation & heating: Air supply or extract under a seat

Pukar Bhandari (070/BAE/225)

Convention Center Design Studio VI 

Upholstery: Thickness of padding should provide comfort & avoid fatigue, material of padding and finish must satisfy fire regulations

Sightlines Horizontal Sightlines It is obtained from spectator’s psychological perception & viewing angle. 

Good view without head movement= 30 degree



Good view with head movement = 60 degree



Maximum perception angle = 110 degree



With full head & shoulder movement= 360 degree



So, fan shape less than 100 degree is preferable due to Sightlines & Acoustic reason in Auditorium.

Vertical Sightlines

The longitudinal section is a parabolic stepped floor as a theoretical rake produced by the sightline calculation. This gives every member of the audience similar viewing conditions. This may be reduced to a single angle or series of angles when applied as described the rake will also be steep. Pukar Bhandari (070/BAE/225)

Convention Center Design Studio VI This is satisfactory for a single tier of seating with no balconies and is especially appropriate for open-stage formats.

Wheelchair location Regulations require a minimum of six places for wheelchair users, or 1/100th of the audience capacity, whichever if the greater. Their location as discrete areas can be at the rear, front, side or within the seating; Wheelchairs can be centrally positioned by forming a bay off a cross-gangway.

Pukar Bhandari (070/BAE/225)

Convention Center Design Studio VI A wheelchair user should be able to sit with a party of friends not in wheelchairs, Sightlines from the wheelchair should be checked, as should the sightlines of those audience members behind. Some wheelchair users can transfer into auditorium seats. Fly tower Where there is a space dedicated for use as a stage, then it is essential to provide this with means of suspension overhead. This suspension to be used for both scenic and lighting instruments. The grid above the stage from where the suspensions come should provide clear walking space above the personnel to move about over the floor area. The received wisdom is to place the pulleys supporting the suspension bridge at high points.

Changing Room requirements      

It should have discrete access Be equipped with secure hanging space Have mirrors with good lighting over vanity tables Have separate toilets & showers Have audio/video feed from performance areas Be equipped with phones and power outlets

Rehearsal Rooms   

Enclosed space without natural light close to the dressing room Sound system, Lighting There should be at least one stage for the rehearsal of performances

Storage room 

20-25% of playing area Pukar Bhandari (070/BAE/225)

Convention Center Design Studio VI Workshops for making scenery  

Should be exclude from main hall due to fire & limited space options 4-5 times the area of main stage

Technical utilities     

Transformer room Medium & low voltage switch room Power batteries HVAC plants Fire sprinkler system

Cloakrooms 

Minimum 4m2 per 100 people

RESTAURANTS AND FOOD COURTS       

Should be planned to achieve variety of seating arrangements. Provide acoustic lobby between restaurant and kitchen. Access should be planned for guest. The service aisle should not be less than 0.9-1.35m if it is to be used by both trolleys and guest. Waiter station should be located so as not to disturb guest. Ambience is an important factor in restaurant design: decoration, lighting should be an integral part. Large regular space should be broken up

The main variables affecting the amount of space needed for the receiving functions are the number, type and type of the deliveries that are to be handled at one time. Ease of opening, checking, moving and stack ability all have a bearing on the space are required.

Serving Areas: 

Serving areas for most table facilities are planned as a part of the main cooking area and separate space determination are not usually needed.

Factors for Restaurant Planning:     



The exterior appearance should communicate clearly, with signs, lighting and many displays. From outside, people should be able to view the interior seating, style and features. Each type of restaurant needs a different identity. Ambience is an important factor in restaurant design. Large regular spaces should be broken up into smaller, more important areas, if necessary by screens or decorative features. Changes of levels are usually favored by caterers but are acceptable provided they make a positive contribution to design, do not involve more than two or three steps, and the main part of the restaurant is on the same level as the kitchen. Raised seating areas should be protected by balustrades. The cash desk may be at the entrance, by service doors or within the kitchen area, depending on the management system.

Food Courts:    

Large halls that house groups of small outlets selling a wide variety of specialist food productions. With attractive displays and a market –style environment, food courts offers a pleasant shopping environment and can be added to supermarkets beyond the check-outs. Storage space for one day’s trade. A bakery, a butcher, cafes & bars, ice cream parlor plus shops etc.

Convention Center Design Studio VI Shopping Malls A Shopping center is a complex of retail stores and related facilities planned as a unified group to give maximum shopping convenience to the customers and maximum exposure to the merchandise. General characteristics of a Shopping Mall: 







The mall usually consists of the principal mall, the major pedestrian shopping street of the project, and one or more subsidiary approach malls or access routes connecting the main mall with the parking areas or adjacent streets. With few exceptions, all stores have their principle entrance on the main mall or, less desirably, on approach malls, whether or not these stores have additional entrances to parking lots or adjacent streets. The main mall can be on one level or on two or more superimposed levels. Each mall level should, however, avoid slopes or steps within its own walkways to avoid hindrance to shopping and a source of accidents. The mall can be:  Open, with weather protection consisting solely of continuous canopies along the store fronts,  Completely covered but open to the air, or  Completely enclosed, necessitating heating in winter and air-conditioning in summer.

General Design Criteria:  





 



 

Column Spacing: One of the significant dimensions in designing a mall is the width of the frontages of stores. The common widths are 20, 25, 30 ft. with the last the most flexible. Store Depths: The stores with depth of 120,140 ft. are commonly used while sometimes the store widths are increased to accommodate larger depths. In the case of basements, the depths are reduced by 20 to 25 percent. Clear Heights: The clear heights vary from 10 to 14 ft. or more with 12ft as an average height. The height should be adequate for air-conditioning ducts, recessed lights, and structural system. Ducts & Shafts: While dealing with the ducts and shafts, mechanical engineers are set up to schedule the location and sizes of the principal ducts and shafts to avoid serious future space problems. Roof Equipment Concealment: Mechanical supports from the engineers are set up for the provision of properly designed and located roof screens and enclosures. Exterior Walls: Depending upon the store’s requirements, service doors, public entrance doors, trash rooms, show windows and other modular designs are suitably accommodated for functionality without disturbing the visual effect. Traffic: The car capacity of road ways must be sufficient to accommodate the traffic generated by the shopping center. Proper signal controls, reservoir lanes, divider strips and other traffic control features must be provided. Parking: Adequate parking spaces should be provided as required. Visibility: Visual communication should be maintained through the use of open wells and shop fronts. Pukar Bhandari (070/BAE/225)

Convention Center Design Studio VI 

Vertical Transportation: Comfortable and accessible transporters such as escalators, elevators and staircases should be provided as requirement to avoid congestion.

Service Entry/Exits:  

Servicing involves the delivery of goods to the various stores and also the removal of thrash and garbage. In the simple strip center, the servicing is customarily by an alley in the rear of the strip of stores. It is desirable to conceal the alley from adjacent neighborhood areas by a wall or landscaping. In the one-level regional suburban center, servicing is customarily by one of the following:  Underground Service tunnels: Usually under the mall, connecting directly to the tenant leased basements.  Service Courts: On the periphery of the building complex, usually partially shielded by 6 10’ masonry walls.  Over-the-curb & Sidewalks: Service trucking routes on the site are often separated from customer routes. These usually connect to fireproof passages at the rear of the stores. Mezzanines are occasionally used to provide storage and non-selling space.

HVAC & Mechanical Services:    

Controls ensure occupant comfort, provide safe operation of the equipment, and in a modern HVAC control system enable judicious use of energy resources. Sanitary and Electrical Duct must be provided at necessary yet convenient spaces. A mechanical control room is placed on top of every lift shaft to contain the counter weight, pulleys and other mechanical systems. An electrical control room is provided usually in the basement to control the regular power supply and backup power supply systems.

Outdoor Plaza:   

Outdoor public space free from vehicular movement. Public activities like strolling, sitting, eating, entertaining, passing leisure time, social interaction and watching the world go by. Quality of plaza determined by livability and social interactions.

Atrium:    

Usually for natural lighting and aesthetics. Can also be designed to enhance buildings cooling system by the help of stack effect. Circulation space arranged around atrium space. Atrium also gives visual connection displays and shops on different levels thus establishing as a common feature of commercial complex.

PARKING General Design Considerations:      



The parking spaces acts as a place for the ceremonies of Arrival & Departure. The basic requirements for parking spaces should be taken from the vehicle dimensions whilst driving in a linear path, cornering and entering into and driving out of the parking area. Parking can be done in various ways: inclined with various angles or perpendicular. Parking can also be done in basement or on surface outside the complex. Surface parking requires less space than the basement parking due to absence of columns. In case of basement parking, there should be enough provision to be economical in this view but for highly commercialized areas where the land value is very high, this can be feasible. In case of basement parking, a relatively narrow column grid pattern can be used, with careful planning and design, reduce building cost and height without any loss of function.

CONSTRUCTION TECHNOLOGY 1. Modular grids/Structural grids: Structural grids are kept as large as practicable. For light-weight roofs with internal heights of 12 meter to 15 meter or more, as required for large exhibition halls, column spacing of 30 meter across the together with perimeter wall columns at 15 meter centres are often adopted. The trusses spanning the bays are usually N- or V-braced, box sections serving also as walkways to give access to overhead services. In larger halls space frames are also used. Smaller halls are based on a 10 to 15-meter structural grid. The location of columns has a considerable influence on booth layout and hence on circulation planning and utility service grids. 2. Wall Construction: The lower areas of walls should be resistant to scarping and in vulnerable places, like external corner, corridors and entrances to goods doors or services elevators, extra protection by covers or fenders is required. Other requirements are concerned with combustibility and-where fire division is involved –the period of fire resistance. It is also important to consider alternative uses to which the hall may be put. For meeting a sound diffusive surface will invariably be necessary to echoes and air resonance from cross reflections. 3. Ceilings: As a rule, the ceilings of exhibition halls are left open for economy and to allow access to ceiling mounted equipment. In the case of a hall providing a clear height of 5m (16ft) or more, the view of the roof structure and associated engineering equipment is above 35 degrees from eye level over most of the floor and the visual intrusion will be minimal. If necessary, this can be further camouflaged by: • • • •

• • • • • • •

Mounting lighting battens and other terminal equipment in the same horizontal plane so that the spaces above are screened. Selecting luminaries which provide a controlled distribution of light below this place. Having a uniform matt dark (black, gray, brown) color of high chrome in the ceiling void For halls of lower height, a formed ceiling construction is usually desirable, particularly if hall is to serve for other purposes. The ceiling must be paneled to allow access to the equipment above and to satisfy other criteria: Easy access, without damaging the panels. Easy-to-clean, permanent surfaces for wiping off hand marks. Robust to withstand handling. Incombustible or very low rate of surface flame speed (class 0 to 1). Modular with luminaries, air diffusers, loudspeakers, sprinkler systems etc. Sound absorbency, depending upon the multiple use of hall. Aesthetic acceptability for the use as a banquet hall or congress hall. Pukar Bhandari (070/BAE/225)

4. Roof Construction: Exhibition halls are usually clear wide span structures. So in case of roof construction it makes some complication with its large spanning property. So the construction technology for the roof is selected according to the requirement of the building. There are different technologies by which one can build the structure. In country like Nepal, concrete technology is widely used for the different type of structures. It gives flexibility of the shape but giving some restriction to the spanning size. There are other technology using steel and glass. This technology gives the flexibility to the design as well as span. Today the world is using this technology in a very wide range for constructing building like conference centers, exhibition centers, auditorium, concert halls, etc. LONG-SPAN STRUCTURE A question can always be aroused that “how long is long span for buildings?” The answer to this question is that the structure with span larger than 20m is called a long span structure. This type of span is unable to be achieved by ordinary RCC structure. Long span or complicated structures can be constructed used different construction technologies. There are different types of structure which should be constructed using the appropriate methods. They are mentioned as below: I. Flexible and non-rigid elements: These types of structures can be constructed using three different methods. They can be constructed in the form of arches, cables and tents. The height of arch in this case can rise with the span of the structure, while the tents are high tensioned structures and are made from special textile. These can cover up to 100m span. II. Flexible but Rigid Elements: These types of structures can be constructed using three different methods. They can be constructed in the form of shell, plates and domes. Shells structures can be made if the ratio of the thickness to the span is 2.4” to 100”. It can be constructed using RC, plastic, glass, metal, ply etc. III. Rigid, Solid and Linear Elements: These types of structures can be constructed using three different methods. They can be constructed in the form of beam frame and slab. IV. Trusses: Truss is very much in use these days. Different kinds of trusses are used to cover different types of structure and of different spans. The large span buildings can be constructed using flat, curved or space truss. Analysis of Long Span Structure Long span roof is today widely applied for sport, social, industrial, ecological and other activities. The experience collected in last decades identified structural typologies as space structures, cable structures, membrane structures and new - under tension efficient materials which combination deals with lightweight structural systems, as the state of art on long span structural design.

The floors are provided with PVC. The seating has been raked (a total of 14 steps from the lowest seating level to the highest seating level) to provide good sight line as well as a good sound line Flooring- Carpet Wall The side of the hall is parallel in front and rear. The wall of hall is made of cavity with use of wooden panels & acoustical material. The hall has 460 mm brick wall with 60mm cavity. The construction of the wall consists of multilayer construction of inner shear wall, cavity in between and external brick wall. Ceiling Specially designed sound absorbing materials like suspended acoustical tiles in particular are used in the ceiling. The tiles act both as sound absorbers and sound reducing barriers. These tiles are ‘random perforated cellulose fiber tiles’ and are prefabricated, factory finished materials. False ceiling near the proscenium is reflective to reflect stage sound to rear the part of hall. Rear portion of ceiling is treated with sound absorbing materials to control audience noise and reverberation. All the Technical space is housed above the ceiling. Furniture Furniture is of wooden and seats are upholstered in leather which acts as a good sound absorbent Doors Instead of simple flush doors, special types of doors are provided for sound insulation.

Exhibition Complex, Bhrikuti Mandap Introduction The exhibition complex in Bhrikuti Mandap is one of the first exhibition complex introduced in Nepal. This exhibition space was introduced by the His Majesty’s government of Nepal in 2021B.S. This kind of architecture at that period of time was considered more sophisticated because this complex was different than the other buildings built in conventional style. Kathmandu is rich in culture and tradition with court, open urban spaces are developed, Exhibition complex on the other hand is modern form for this age.

Location The exhibition complex is located in the heart of the Kathmandu city adjacent to the city bus park and 6 Km far from Tribhuvan International Airport. Several monumental buildings like the Royal Palace, Singha Durbar and also temples like Bhadrakali and Mahankaal lies in its close proximity. A lot of social and religious establishments gravitate around it. The place sits right across the exhibition road and the nomenclature of the road itself comes from the ever popular facility of Bhrikuti Mandap. Site and Surrounding The Bhrikuti Mandap is slightly lower form the level of Tundikhel. The site provided for the exhibition is more appropriate in terms of services as transportation, commercial facilities, Hotels, etc. Site is located at center of Urban Area. Design Consideration of the complex The present design of Bhrikuti Mandap is very much focused on the proposed initial design. The exhibition ground is centralized with crushed stone paved pathways on cardinal directions. But the concept is modified and the proposed Exhibition ground is converted as Adult Park garden. There are two entryways- one leading to the exhibition hall and stall areas and another that leads to the dragon world, the amusement area. The dragon world has a separate exit way. With change in time, big hall is built as per the demand of permanent structure. Basically the design is considered on different sectors. Eastern part is developed as children’s park, west and south part is provided for open lawn but to this date, land is taken as parking area where as the south wing is provided as permanent Exhibition hall. Central concentrated circle is used as an adult park with several fringe gardens. The third part is covered with stalls with different offices and shops. The end peripheral areas are over crowed with Khula Bazars and are also famous as Hong Kong Bazar. The road projection on diagonal axis is drawn on efficient way as tried to do more facilitating the spaces. But the peripheral areas are not approached with pathways. It seems that these areas are at greater distance from the center. The concept of sustainability is greatly over flowered on the proposal design with the open exhibition system on the ground which is not embraced on the existing exhibition ground due to design considerations.

The Exhibition Hall The main exhibition hall of the Bhrikuti complex covers an area of 3250m2 on the ground and is laid out in conformity with the semicircular road bounding the hall. It is a simple structure laid out in grids of 6m by 20m. The 6m high triangular truss stands above 6m from the ground and holds a GI sheet roof. A clear 6m height within the hall gives a flexible space for exhibition and the day lighting brought in by the roof light spares the wall area punctured for lighting purpose. This adds to the flexibility of the interior space.

Pukar Bhandari (070/BAE/225)

Convention Center Design Studio VI It also complies with the standard requirement of clear wall area up to a height of 6m for an exhibition hall. It is the one and only exhibition hall, yet pushed aside from the main entrances to the exhibition ground. It lacks several amenities like storage rooms, Lavatory and an office space for the exhibition organizer and even parking facility. There are a number of entry and exit doors giving flexibility for multiple choice of laying out the floor plan for exhibition. The hall is an empty box without any facilities. The designing hall is quite appropriate for small and medium level exhibitions but it cannot cater for lager exhibitions in a proper way. So it does not meet any standard exhibitions facilities in standard fairs, expos and these kinds of events.

Zoning of the Bhrikuti Mandap Complex

Fig: The interior of the hall showing skylight

The ground can be studied with dividing different Zones as below: Exhibition zone: The main hall is acting as a shade without any facilities so the concept is not clear on the context of Nepalese society about the exhibition fairs etc. The hall is empty box without any toilet, water supply, store, sound and lighting room and other facilities. The design hall is quite appropriate for small and medium exhibition in terms of size but it could not be sufficient for an idle exhibition in proper way. So it does not meet any standard exhibition facilities in international standard expos, fairs and these kinds of events. The north wing of exhibition ground is converted as Adult Park. This is opened for office hour and days with entry fee. The parks with monuments semi covered pavilion, water pond is fragile art of the ground but the lack of proper maintenance is the degrading point to the exhibition ground. But still some open to air exhibitions are held here. Different programs like food festival, film shooting, etc. are launched inside of the garden but the lack of proper maintenance make repulsion to such activities. There is not a great attraction event in garden is considered as a part of heaven. Part of its land is worked out as a Nursery House. Opening time is very limited and spaces are not well busy with an activity, this is basic reason behind the derogation of the park area. The North West lawn is also a part of open to air exhibition but in the present date it has been used as parking space. Amusement Zone The northern east wing as a children park is embraced as an exhibition ground. It is carrying its own identity and regularly progressed with the mobilization of different programs. Children’s Park is worked out as isolated part, diverted through the separated gateways and there is no interconnection between the children’s park and the exhibition ground.

Pukar Bhandari (070/BAE/225)

Convention Center Design Studio VI

Although the proposed design of Children Park is not considered for the future demand and extension, it becomes one of the important entertainment world due to introduction of the Dragon World. Because of such new entertainment games the good investment is itself carved out on the exhibition ground and becomes a center of attraction. But still certain obstacles to the children’s park are seen like the fencing problems. Fencing through the board and as a part of advertising board, has drastically deteriorating the park. It has act as a visual barrier to the inside world. This has badly affected the psychological restriction and same oddness and insecure feeling to the people. As an architecture element, it should be visual art but here the art is covered with veil. Commercial Zone About ninety stalls are constructed in appropriate size and shape in order to sustain. They are established to provide maximum benefit and comfort to visitor with short distance path but the proposed design is not properly managed. The concept of the exhibiting Fairs, events, shows are changing. Mobilization of the spaces and the mass is not demand of today. Integration of spaces and mass in proper ways is basic concept of exhibitions. Today the supporting zone covered with small shops which catering the neighborhood Khula Bazaar. Due to long route of the stalls and scattering manner makes repulsion to visitors. There is no easy service route which is main defect on the planning. On the proposed design the permanent structure of the Exhibition hall is not considered, and it is later built over hiding supporting area. Shops of the Tundikhel (Khula Manch) were relocated towards the free areas in bank of the Bhrikuti Mandap. This market area is developed in much devastating way and destroying the cityscape and beauty of the Exhibition Ground. This bazaar covers 15.7% of the total Exhibition ground. The bazaar lies on the lower gradient from the road and has drastically changing the vision of the surrounding. The land of the exhibition complex near to Prithivi Marg is very high cost land but today the land is seen to be cheap. The purpose of the planning is diverted from the master plan. It seems that Khulla Bazaar is increased due to lack of proper management. Institution Zone The office of administration along with some other offices is sited in this zone which was also not in initial planning. A part of North West wing is covered with Tourism Board which is drawn for different purposes and program. The area coverage by it is 3.5% which is positive aspect for the Exhibition ground. The administration has leased the land to Nepal tourism board for 99 years. There are some other offices too which are located in this zone. This zone lies in the North West of the site.

Conclusion The provision of sufficient gateways on the main exhibition road defines different nodal point as servicing facilities. The basic purpose of the Exhibition ground not only focused on Fairs but also on entertaining people in different ways as time demands. The location of site is much more

Pukar Bhandari (070/BAE/225)

Convention Center Design Studio VI appropriate regarding all the aspects of the Exhibition facilities. Through the analysis it is seem that the ground has not cater different activities for different time schedule. The basic reason of it is that design of this ground is not intentionally build for breathing activities and to meet today’s facilities like cinemas, theatres and restaurants. During exhibition and fairs, the shops running within the areas of the Bhrikuti Mandap are run in profitable way but at the time of off season these shops are closed due to lack of customers. Furthermore, the standard of the shops are also could not maintained by the hygienic and quality of shops are below general people so that people of outside areas of the Bhrikuti mandap does not prefer to go there for shopping purpose. The space and land were not carved as exhibition facilities. Children Park is fulfilling and providing entertainment to the citizens in spite of limited and compact area provided for that purpose. The introduction of the Dragon world has keeping positive impact on the society and hopefully increasing with in few years. Lots of stall and built areas like ticketing house is not well integrated to each other. It seems that there is not proper condition of services regarding toilet, solid waste, dumping and improper landscaping, insufficient lighting and water supply. The basic requirement for the exhibition is Big Store for the machineries, installation room, sound and lighting room are not available in the exhibition ground even it is only exhibition complex in the country.

Convention Center Design Studio VI A large skeletal staircase at the front leads people directly towards the main foyer whereas the office area is hidden from direct approach. Service entrance is also hidden which is located at the east side with a provision for vehicular access. The complex seems to be planned about the axis created by the main entrance. Foyer The foyer space in the city hall is more defined and usable as it also acts as a spill out area, gathering and interacting space and also the space for holding exhibition. The foyer space is designed as a mezzanine opening up two floors. The foyer enjoys the depth of height as a void is introduced on the second floor.

Architectural Expression Architectural style: modern Based on modern principles of design, the building reveals the symmetric nature along the axis of entry. The building exhibits dynamic nature in form. Various forms used create a variety in design. Use of different colors and textures for different surfaces adds visual interest in the exterior look. Vertical linings on the front façade give verticality to the structure. Fig: view from the road side

Elements of visual communication The uniquely designed gate is in perfect harmony with the building form. Entrance to the main buildings is through the dominating and dynamic gate structure which seems to have been built in perfect harmony with the auditorium. The wide external staircase leading to the first floor entrance foyer reflects the public nature of the building. Front landscape lawn with plantation and water body as the elements of visual interest. Projecting blocks of auditorium also creates visual interest in the building.
