Introduction

1.1

The Imperial Cinema

The Vine Christian Fellowship (The Vine) has entered into a 15-year tenancy agreement to turn the existing Imperial Cinema at 29 Burrows Street, Wanchai, into their new Vine Centre 2. The Imperial Cinema is about 40 years of age and was first constructed around 1969. The cinema has since undergone several alterations over the years converting the original single theatre into smaller theatres to adapt to the changing trend of the cinema entertainment that prefers smaller intimate atmosphere. The original cinema was a single theatre comprised of a main viewing hall with a raked floor seating and an upper balcony in stepped seating with a total seating capacity just below 1300 persons. Major alterations and additions were carried out in the following years:

1.2

1. 1986 – 87:

First A&A submission dividing existing theatre into upper and lower theatres by means of lightweight steel beams and steel plates; and alteration of access staircase to U/G.

2. 1997 – 00:

Structural changes to staircases from G/F to U/G and division of lower theatre further into 2 smaller theatres.

2. Provisions of full sprinkler coverage to the entire building to satisfy the current Fire Services Code and to meet the current PPE requirements;

new vision to do more community works to reach out to the Wanchai community.

3. Total overhaul of the outdated existing air-conditioning system which has been left idle for the past few years;

To ascertain the development restrictions on the building lot, Synthesis has ordered the Land Lease for the cinema building from the Land Registry and found that the lease conditions on the Lot were rather general and there were no specifics on the limits for many of the development parameters as one might expect from the land leases of more recent time, such as, maximum allowable Gross Floor Area, Building Height Limit, etc.

4. Total replacement of existing plumbing and drainage systems which has not been used for the past few years; 5. Re-roofing of the entire existing roof as there were extensive water damage on the ceiling of the balcony floor; 6. Unauthorized building works (UBW) on the roof: existing metal shed housing the A/C System and another small structure on the roof are both UBW’s which are required to be removed.

1.3

Addition of New Floor Areas

In reviewing the layouts to meet the projected needs of the Church, The Vine has requested Synthesis to explore the possibility of adding more floor areas to the existing structure since the current configuration of the floor plans can only provide a large worship venue for their Sunday services with few breakout space, there are no other usable/functional floor areas to accommodate the uses by their different ministries, including the Church’s

The findings seemed to be consistent with the existing record plans on file with the Buildings Department that no reference to the Gross Floor Area (GFA) was found in any of the original building submissions all the subsequent A&A submissions made over the years. In the major A&A Works carried out in 1986-87 in which a new slanted steel floor structure was added to the building, no calculations with respect to the new GFA were found in the approved plans. After having discussion with our own Authorized Person who is more familiar with the Building Regulations and practice of the time, it seemed like adding more floor areas to the building could be feasible as long as the same building envelope is maintained. The proposed addition of floor areas, however, will be subject to approval by the Buildings Department and the Lands Department when we submit the A&A works formally.

Due Diligence Process

The adaptive re-use of the Imperial Cinema was first considered by The Vine in Jan 2007. Synthesis was asked to assist in providing assessment on the existing structure in terms of statutory compliance and building system upgrades in order to bring the building up to the current health and safety standards as the cinema had been left unoccupied for a number of years. The project was not considered viable at the time because of costs reason. In February 2009, Synthesis was approached by The Vine again to assist them in the due diligence process for a possible long term lease on the building when the Church was presented with the opportunity again after a defaulting lease by the last tenant who had their land use permission rejected by the Town Planning Board. The Imperial Cinema was originally designed as a Place of Public Entertainment (PPE), whilst most of existing planning of the Cinema can still meet the current requirements of the Building Regulations and the subsidiary codes and the Fire Services Code (Code of Practice for Minimum Fire Services Installations and Equipment), the following deficiencies were identified for major upgrades: 1. Addition of a Fireman’s Lift to meet the requirements for PPE in accordance with the Code of Practice for Means of Access for Firefighting and Rescue. The Fireman’s lift can be doubled up as a disabled lift to satisfy the accessibility requirements to Barrier Free Design Manual, 1997; Existing Cinema Building Section Showing the Slanted Steel Floor Deck Revision 0

1.4

Positive Structural Feasibility Result

With the possibility of adding more floor areas, the Church then commissioned Wong & Cheng Consulting Engineer in April 2009 to carry out a cursory structural feasibility study for the addition of a new floor at the First Floor Level. The new floor would become the new Main Auditorium where some of the stepped balcony seating would need to be demolished to create headroom for the new floor. The combined capacity of the new Main Auditorium would be about 700 seats, which was generally agreed by the Church leaders to be the minimum acceptable seating capacity for the new centre. The result of the structural feasibility study came back positive for the addition of a new floor at the 1/F and a new small office on the lower roof by the existing water tanks. The latter, however, was not adopted because of the major structural strengthening required on the existing roof beams and slabs; and the provision of access in compliant with the Barrier Free Design to the new office was found to be problematic. Refer to attachment in Appendix A1 for WCCE’s Feasibility Result. The positive structural feasibility result enabled us to turn the current main viewing floor at U/G into a “Ministries Centre” with a number of multipurpose type rooms including a large “Multi-Purpose Studio” area for medium size gatherings. This new ministries floor will allow the Sunday School to be held in the same building concurrently with the Sunday Services, and it is envisioned that the new Ministries Centre will be the active area where the different ministries of the Church can hold meetings and gatherings throughout the week. Sketches of the proposed layouts and section are appended with this report in Appendix A2. The proposed layouts have formed the basis for the consultancy services for the Project Team 1.5

Land Use Permission

The Imperial Cinema is situated at the Inland Lot No. I.L. 7967, which is zoned for “C/R Use”, i.e. for commercial and/or residential development in accordance with the Outline Zoning Plan (OZP) for Wanchai, Approved Plan No. S/H5/25. “Religious Institution” is written under Column 2 of the Schedule of Use for Commercial/ Residential Use of the Explanatory Statement and Notes for the Wanchai OZP, which means the conversion of the cinema building into church usage would require a Land Use Permission by means of a Section 16 Planning Application to the Town Planning Board (TPB) of the Planning Department. The Section 16 Planning Application is in general a two (2) months process. When a Section 16 application is received and found in order by the TPB, they will then conduct a 3-week public consultation process to solicit comments from the people in the neighborhood by posting a public notice on the premises concerned.

consultation. Majority of supporting responses will normally warranty an approval of the proposed usage, however, the reverse may not be always true. The PTB will generally look for consistency of use with the characters of the surrounding neighborhood. In our case, there are a couple of religious institutions already located within the same Lot at the base of the residential building, Wah To Building, behind the Cinema. In our Section 16 Application, we have included a few precedent cases from the PTB record concerning similar conversions from Commercial to Religious Institution Use. We should expect a straight forward approval for our Section 16 Application. Synthesis submitted the Section 16 Planning Application to the Planning Department on 24 July 2009 and supplemental/amended information on 28 July 2009. Shortly after our submission, the TPB has initiated the public consultation process by posting a public notice outside the cinema building on 1 August 2009. The Public Consultation Period will end on 21 August 2009. PTB has also informed us that a Board Meeting has been set up on 18 September 2009 to review our application and by which time a decision shall be reached for our application. Copies of the Section 16 Planning Application documents and the letter from the Town Planning Board are attached in Appendix B1

2.2

Review of Land Lease and Record General Building Plans

Land Lease Both the record General Building Plans and Land Lease had been retrieved during the due diligence process prior to the formal commencement of the Project. For A&A works, It is paramount for the Project Team to review and understand the original design parameters for the existing structure based on the Land Lease conditions as well as the planning and design assumptions stated on the record plans from the Buildings Department. A Land Lease stipulates the rights and duties of both the Government and the Tenant, it also includes very specific design parameters to control the proposed development, such as buildable floor area (Gross Floor Area), massing, height and other facilities like parking number and landscape areas, access, etc. Wanchai Outline Zoning Plan No. S/H5/25 Showing a “C/R” Use for our Lot

The Section 16 Application documents including those drawings showing the diagrammatic layouts of the proposed usage of the cinema building will be open for inspection by the public at the Planning Department Office in North Point. All comments received will be made available for public inspection until it is considered by the next TPB Meeting after the closure of the public Revision 0

The Lease for our site was renewed on 12 December 1963 for another 75 years. The provisions of the Lease were rather general and contained no specifics for any of the development parameters mentioned above, this gave some leeway in interpreting the allowable buildable area, i.e. GFA, for the building.

A copy of the Land Lease for the Project Site is attached in Appendix B2 for easy reference. 4

Record General Building Plans The record General Building Plans provide valuable design information of the original planning and design assumptions: a)

Classifications of the different usages within the building, hence the Fire Resisting Construction of the building (The original building was designed as a PPE);

b)

Original design populations for the different theatres and the maximum capacity of the discharge values of the escape staircases;

c)

Provisions for means of escape in terms of minimum required and provided dimensions for the widths escape routes and exit doors

d)

Provisions of sanitary fittings in terms of minimum required and provided numbers of fittings for urinals, water closets and washbasin for both female and male;

e)

Detailed dimensions of the layouts;

Synthesis has input the building plans, sections and elevations of the cinema building based on the record General Building Plans into our CAD system. The proposed modifications on the CAD system has been issued to the subconsultants as design background during the Inception / Feasibility Stage.

2.3

Establish Design Brief & Preliminary Layout Plans

One of the major objectives for this Workstage is to establish the Client’s Design Brief for the Project Team, i.e. the spatial and functional requirements from all the ministries of The Vine. Synthesis has worked closely with The Vine’s Building Project Coordinator to solicit the detailed requirements from the different ministries head of the Church. A Summary of Ministries Requirements and a Ministries’ Facilities Usage Table based on the weekly usage of the current Vine Centre were received from The Vine. Refer to attachments in Appendix B3. These ministries requirements have been used as the basis for the planning and design of the preliminary layouts of the proposed new Vine Centre 2. Refer to attachments in Appendix B4 for Preliminary Layout Plans.

Synthesis has been working closely with the individual consultants to ensure all the constraints and issues of the existing or future building systems are clearly identified and analysed with proposed possible solutions before proceeding to the next Schematic Design stage.

over by the new Main Building Contractor. The main purpose of this process is to avoid the need to report completion for the demolition works and wait for BD’s acknowledgement of the completion before the A&A can be commenced.

Single Contract Approach Key Dates It was concluded that a single Main Contractor should be responsible for carrying out the structural demolition and alteration works followed immediately by the renovation works to both the interiors and exterior of the building. This will ensure a single un-interrupted construction process without any possible need for the Buildings Department to acknowledge the completion of the demolition works or sections of the works. The acknowledgement process could potentially stall the construction works after the demolition of some of the major structure components of the existing building.

Scheduled Move-in Date

The proposed single-contract approach master programme is comprised of a 5 months Design Stage and 9 months of Construction which includes two months for the structural demolition works. The tender evaluation and award for the Main A&A Tender Works Contract will be carried out concurrently with the demolition works. The single-contract approach also allows the Project Design Team as well as the Client’s Project Team more time at the beginning of the project to establish the Design Brief with more resolved layout plans for all government submissions. A two-contract approach with separate contracts for the demolition works and the subsequent A&A and Renovation works would require the Demolition Plans and General Building Plans to be submitted almost immediately after the commencement of the Project which is not practical.

Novation of Demolition Contract with the Main Contract “Novation” is a term used in contract law and business law to describe the act of either replacing an obligation to perform with a new obligation, or replacing a party to an agreement with a new party. Because of the need to submit the demolition plans and tender the demolition works ahead of the main A&A and Renovation works which require longer time to prepare, it is proposed that the Demolition Contract to be let out ahead of the Main Contract.

2.7

Site Clearance Contract

It is intended a site clearance will take place soon after the project commencement to remove all the existing finishes to clear out the site prior to the final structural demolition works. The site clearance tender was issued to three (3) prospective contractors in early July 2009. Due to the presence of asbestos in some of the materials inside the building, an addendum to include the removal and disposal of the asbestos containing materials was added in mid July 2009. The final quotations were returned on 22 July 2009. Interviews were carried out on 29 July 2009 to clarify the queries on the submitted quotations and to verify the tenderers’ understanding of the scope of works involved. Removal of asbestos containing materials would require the engagement of a registered asbestos consultant and a registered asbestos contractor in accordance with the Air Pollution Ordinance. All site clearance can only commence after the consent is given by the EPD inspector. The Owner of the building has been informed of the site clearance contract due to take place in August 2009 and they have been advised by Synthesis to remove all their belongings out of the premises before the end of July 2009. During the removal process, the Owner’s removal contractor has also removed all the existing fixed seats and other existing audio/visual equipment within the cinema including the A/C mechanical plant on the roof. It was agreed with the building Owner that the three (3) existing projectors inside the project booth plus the chandelier at 1/F would be saved because of the potential values in reflecting the history of cinema designs of Hong Kong. They have been set aside for relocation and refurbished by the Hong Kong Film Archive. The Vine has expressed their interest in retaining one of the projectors for display at the main entrance lobby/café in the future. The Site Clearance contract is expected to be awarded in the later half of August 2009. Meanwhile, a fourth quotation is being reviewed by the Architect. There are about 1 to 1.5 months of float time on the Master Programme between the site clearance contract and the demolition works, the longer evaluation time for of the site clearance contract should not have major impact to the overall programme.

3.0

Structural Design

This section summarizes the detailed assessment and analysis on the proposed structural alteration and addition works that are required to satisfy the proposed layout changes to the existing structure as well as provisions of the prevalent building regulations and codes: a)

3.1

Provisions of the current health and safety codes and regulations under the Hong Kong Buildings Ordinance and Code of Practice of Fire Services Installations;

b)

Addition of new floor areas to cater for uses by the different ministries of the Church;

c)

Demolition and leveling off existing floor areas at U/G to improve the internal ambience and usage of the new Vine Centre;

Disabled/Fireman's Lift

Originally Proposed Location: reinforced concrete lift core directly on the top of pile cap between existing column C11 and C12.

9m3 Increased Fire Services Water Tank Capacity

Site constraints and limitations

3.5

The existing beam 1B-26 is the major element of the wind frame along Grid Line 4, forming two openings on it will totally cut the main reinforcements of the beam which will weaken the rigidity of the original wind frame. To compensate for the loss of rigidity, either of the following options has to be carried out to reinstate its original rigidity.

Assessment:

Option 1:

Option 2:

enlarge the upper and lower parts of the existing beam 1B26 first and then introduce two openings (size: 2200(H) x 1800(W)) on the existing beam.

Due to the increased water tank capacities to satisfy the current F. S. requirements in accordance with the Code of Practice for Fire Services Installations, new weigh of approximately 100kN will be added to the roof near column C9 and C10. Strengthening works for the affected beams and columns may be required. Please refer to Appendix C5 for proposed location of the additional water tank.

totally remove the existing beam 1B-26 first and then reconstruct it by introducing a large opening (size: 2200(H) x 8629(W)) on it.

Please refer to Appendix C2 for the proposed openings and the extent of strengthening works.

3.3

Additional Floor

Proposed Works: Add an new floor slab across the void over the U/G from Grid Lines 5-10/A-D at level 13.0m mPD

Site Constraints and Limitations Extent and Nature of Works Existing structural reinforcement drawings and calculation records for the pile cap are missing from the BD Record, and it would be possible for the Registered Structural Engineer to prove to BD that the existing pile cap can sustain the additional load from the installation of the proposed lift core. Therefore, we need to position the new lift shaft location away from the existing pile cap area.

Revised Location: To be relocated directly on the soil ground near column C11 to avoid interaction with the existing pile cap.

The additional platform will be functioned as an auditorium with a design imposed load of 5kPa. To minimize the sound transmission from the proposed floor to the classrooms underneath, the new floor will be constructed as a normal weight concrete “Bondek” profile sheet composite slab with a maximum thickness of 125mm. All loadings from the composite slab will be transferred to the existing R.C. columns through structural steel supporting framing. Please refer to Appendix C3 for the plan and section showing the location and level of the proposed new floor.

Advantages 3.4 a)

Self-stand concrete reinforced lift shaft can be constructed to provide 2 hours FRP;

b)

all loadings from the installation of the proposed lift shaft and lift pit will be transferred directly to the underground soil; and

c)

No checking for the existing pile cap is required and may be approved by Buildings Department.

Please refer to Appendix C1 for the revised location.

3.2

Openings Through Existing Wind Frame Along Grid Line 4

Proposed Works: Forming two openings of size 1800 mm(W) x 2200 mm(H)) on the existing wind frame member, beam 1B-26.

Revision 0

Roof Loading

Assessment: The existing roof was designed as a non-accessible roof with loading designed for roof maintenance only. According to the Building (Construction) Regulations, the design imposed load for a roof without direct access is only 0.75kPa and no additional occupancy is allowed. Therefore, the proposed mechanical plant area along grid lines 7-8/A-D for accommodation of chillers and AHU should be relocated as its design imposed load 7.0kPa is much larger than that of the existing roof. WCCE recommended to relocate the proposed plant room along Grid Lines 34/A-D as the removal of the Projection Room will compensate large part of the additional loads from the installation of the of the new plant room. Please refer to Appendix C4 for existing roof design imposed load.

4.1

Mechanical Ventilation and Air-Conditioning (MVAC)

The Existing Cinema Building a)

b)

Based on the site inspection record, there is a concrete air conditioning make-up water tank with volume of 22.7m3 on the roof. Existing MVAC system comprised of water cooled chiller, cooling towers and air handling units with correspondence panels and motor control centre house in a sheet metal shed on the lower roof. The entire existing MVAC System shall be removed and replaced by a new system.

Background The preliminary cooling load estimation indicates that the peak simultaneous cooling load is around 130 refrigeration ton (457 kW). The exact cooling load will be calculated and updated in the detailed design stage when the building design, materials, finishes and internal loads are finalized. Winter heating will not be provided in all areas. The aim of this part of report is to list out the pros and cons between watercooled and air-cooled systems for further analysis before a decision can be made.

Air-Conditioning Schemes Heat rejection is required by all types of air-conditioning systems and should therefore be determined prior to the consideration of the refrigeration plant configuration, as it affects, in principle, the physical sizes and weight of the system to be adopted. There are several popular schemes of heat rejection from refrigeration plants. The selection depends on the availability of heat sink, i.e. where heat is rejected, environmental acceptability such as noise, air pollution, aesthetics, heat, building space available, local regulations, equipment applicability, capital, operating and maintenance costs, etc. The commonly used heat rejection systems in Hong Kong are as follows: Option 1

Evaporative cooling – using cooling towers

Option 2

Air cooling – using air cooled chillers

The other uncommon/unpopular systems (eg. seawater cooling and air cooling with air/water radiators) will not be analyzed here as they are not applicable / appropriate for the proposed new Vine Centre.

in the existing cinema. The cooling water leaves the water-cooled condenser in a chiller and enters the cooling tower.

Chiller Plant Option The temperature of the condenser water will be lowered as it vaporizes when it passes through the cooling tower. Due to the evaporation loss, drift carryover in the cooling tower and the blowdown, an extra 1 to 2% of circulated condensing water is required to compensate for the water loss. The bleed-off volume ranges from 0.05% to 0.6% (already included in the aforesaid 1 to 2%) is dependent on the prevailing conditions of air contaminant, water supply quality and the method of water treatment. Quantity of make up for the cooling water is about 0.0025 L/s/RT of cooling capacity. As water and sewer services are purchased from the Water Authority and Drainage Authority. The average unit charge of water-related utilities is as follows: x x

Water Authority’s average cubic metre charge for freshwater is HK$4.8 Drainage Authority’s average cubic metre sewage charge is HK$1.5

Option 2 - Air Cooling Packaged air-cooled chillers are available in the market, and the smallest rating available is approximately 50RT. Each packaged chiller consists of condenser coils for direct cooling of the refrigerant of the chiller. Packaged air-cooled chillers are normally located on the roof of buildings where the heat can be rejected to the ambient air. Open area will be required for housing the chillers. Considering the space and structural constraint and in order to meet the estimated cooling load, 2 chillers of approximately 65RT each in 50/50 configuration, i.e. each chiller to provide 50% of total cooling capacity required and 50% spare cooling capacity maintained in case one of the two chillers breaks down. An approximately 1540m2 roof area will be required to house all these chillers. Locating the air-cooled chillers on roof will affect the aesthetics as the Church building is surrounded by high rise towers, including the residential tower block on the same lot. The noise and heat generated by the fans/condenser will affect the high rise towers. An acceptable noise mitigation scheme for these chillers will be further studied. An air-cooled chiller plant will have a lowest coefficient of performance when compared with water-cooled counterpart. Therefore the cost of energy consumption for operating an air-cooled chiller plant is much higher than water-cooled system (about 30% higher which is approx. HK$ 305,597 annually). The details of the pros and cons of the two options are described in the following table:

Option 1 - Evaporative Cooling In the evaporative cooling scheme of a chiller plant, cooling towers are used and continuous water make up is required, which is the system that was used Revision 0

Maintenance Costs

Design Criteria

Water-cooled system using cooling tower with more piping and associated equipment will require more maintenance work and thus maintenance costs. Air-cooled chillers, however, require less maintenance costs as the system contains no condensing water loop and the accompanying pumps and pipes.

Capital Cost

HK$ 780,000

HK$ 550,000

The annual maintenance costs of water-cooled system for the proposed development is about 30% more expensive than the air-cooled counterpart, i.e. an additional outlay of approx. HK$ 3,450 will be required if water-cooled system is adopted.

Industrial sources indicate that the operating life of both water-cooled and aircooled chiller compressors are similar, approximately 15 years. HK$ 123,750

HK$ 1,667,998

HK$ 6,139,990

Assumptions: 1. The cooling requirement is about 130 RT 2. Operating hours: 8 hours per day & 365 days per year 3. Electricity cost: HK$1.0 /kWh 4. Year round cooling load diversity factor = 0.6 5. Option 1 – COP for Water cooled plant; total input power: 1.2kw/TR 6. Option 2 – COP for Air cooled plant; total input power: 1.6kw/TR

The life expectancy of both the water and air coils is in the region of 10 to 15 years. The replacement cost of the air coil is about 100% more than the water coil, i.e. approx. HK$22,000 and HK$11,000, respectively. While the cost of the air coil is higher, we believe that the difference will be cancelled out by the fact that the water-cooled equipment will require greater maintenance, parts and replacement. Therefore, we do not consider the maintenance and replacement costs contribute any significant difference to the cost comparison exercise. As indicated in the last four rows of the Table above (which are derived from a simple computer worksheet), the additional outlays of water-cooled system on capital and maintenance costs are way outweighed by the running costs. That is, cost saving is not significant with 3 years. Therefore, we do not recommend the use of water-cooled system, considering the site constraints and the pilot scheme processing time. Aircooled System is proposed for this Project and the plant equipment locations shall be further coordinated with the Architect and the Structural Engineer.

Life-cycle Costs

Scope of Works

Life-cycle costs are the important elements for consideration in the selection of heat rejection system. They include the following:

Air-conditioning system will be designed for the following areas:

Capital Costs For the required cooling capacity of 130 RT for the proposed development, water-cooled chiller plant cooling towers is more expensive than air-cooled counterpart (about 30% more which is approx. HK$230,000). Operating Costs The operating costs include the running costs of refrigeration machine and the associated fans, pumps and equipment. The costs will also depend on the energy efficiency of the machines. Considering the refrigeration machine itself, water-cooled system is more energy efficient. The electricity costs of water-cooled using chiller plant of the proposed development as a whole is about 30% lower than that of the air-cooled counterpart, i.e. approx. HK$ 58,819 annually could be saved for electricity costs if water-cooled system is adopted. The net saving of running cost from water-cooled system is about HK$ 882,285 over a lifecycle of 15 years..

Soil and Waste Drainage System Existing drainage system is modified to suit the proposed layout plan and try to run to connect to existing manhole which is located at G/F of the church. Sump pump system will be considered as last resort for new lavatories above existing shops/noodle shop at G/F. Existing Condition Based on the BD’s record drawings, the existing drain riser pipes of the residential building are running inside the cinema as per the attached plans. Those drain pipes should not be dismantled and, during construction, if any connection required, should be commenced in schedule. For manhole connection, since existing manholes are located at existing noodle shop at G/F, connection of drains from the new toilets above the shop/noodle shop, it’s unavoidable to connect the sewage drain at locations outside the project boundary. Further study of the arrangement is needed Scheme Design Option

Potable Cold Water System Existing Condition

5.1

Acoustics

Shen Milsom & Wilke has been engaged to conduct the study and investigation of the conversion of the Imperial Cinema for The Vine. The objective of the study aims to improve the acoustic environment of the church to suit the intended usage and purpose. This report summarizes our initial recommendations and outlines our understanding of the acoustical requirements based on the drawings received dated 15 July 2009 and the subsequent discussions in the weekly meetings. A site visit outside the cinema has been conducted so that a better understanding of its location and the acoustical aspects in relation to the adjacent buildings is obtained.

5.1.1

Sound Insulation

The basic requirements for good hearing applied to any building occupancy are comprised of the control of unwanted sounds and control of the sounds generated within the listening space.

Interior Wall The wall separation between individual rooms shall be constructed from full height drywall partitions. In general, the drywall partitions to be erected would be in the range of thickness between 105 – 160mm which would offer acoustic rating between STC 45 – 55. The proposed partitions would generally provide sufficient sound isolation to the Offices, Meeting Rooms, Classrooms and Green Rooms. In other areas, it is understood from the layout plan that the Meeting Rooms are arranged so that they are situated adjacent to the Multi-Function Room. We have concerns that the noise and low frequency beats of music generated inside the Multi-Function Room would be powerful enough to penetrate into the Meeting Rooms and affect their normal operations. A thicker and better acoustically rated wall is advised between these two areas. The sound level inside the Multi-Function Room is expected to reach 90 dBA. Initial recommendation would be a STC 60 partition with overall thickness of 235mm. This arrangement of partition should be appropriate to isolate the air and structural borne noise satisfactorily so that the Meeting Rooms could achieve their intended acoustic criterion. The construction details of the drywall partitions and their locations can be referred to section 2J and the Appendix respectively.

Function Room, depending on the functions being held inside, acoustic door of STC 45 may be required to enhance the sound separation. Typical solid core door with perimeter acoustic seals could be applied to places such as Meeting Rooms and Classrooms. In regards to the door seal, we recommend Zero International, or equivalent: Table 1 – Recommended acoustic door seal models Acoustical Seal Position

Control Room Glazing Criterion The site performance of partition, door, and window is stated in terms of NIC (Noise Insulation Class) rating, where STC (Sound Transmission Class) is used to specify the laboratory rating. It should be noted that the NIC value is typically 5 – 8 points or so less than the STC value for drywall and 2 – 3 points for block wall, due to variability of field conditions and/or work quality. Exterior Wall Noise intrusion to the church due to traffic is not anticipated to be an issue since it will be surround by both residential and commercial buildings close by. Traffic flow was found not to be frequent at the road in front of the church. Since at the ground level, only the entrance Lobby will occupy the space, minimal noise nuisance is expected to affect ground floor. The more noise sensitive spaces such as Multi-Function Room and Main Hall are located on the upper floors of the building and noise intrusion from outside of the building is not expected to be an issue. From the drawings obtained, we believe the exterior structural wall is concrete with thickness of about 250mm. The current wall could offer acoustic rating of about STC 59 which provides sufficient sound isolation from the outdoor traffic to the aforesaid spaces. In regard to the noise impact from the church to the adjacent building, our current assumption is that there is a structural break of over 50mm between the minimum 200mm thick exterior wall of both buildings. Assuming that the two exterior walls were built correctly without bridging, we do not anticipate sound transmission from the Main Hall to the adjacent building will be an issue.

Revision 0

Sound isolation between the Main Hall and the adjacent Control Room located behind it would depend on the functional requirement. The requirement is minimal (single 12 mm plate glass) if it is desired to have sliding window given the location of the room is high from audience floor. However, from the drawings provided, it is believed that the Control Room would act as a general control zone for overlooking the performances being held at the stage and hence the requirement of the glazing would not anticipate to be stringent. This can be confirmed during Detail Design stage when there is user requirement.

Zero 926N Zero 8878AA

Translation Booth From the layout plan, a Translation Booth will be located behind the Main Hall next to the Control Room. It is understood that this Translation Booth would require a certain degree of acoustic isolation and hence the walls should be constructed with STC 55 rating. The glazing separating between the Booth and the Main Hall should be at least double glazed. Each of the glass panes of the double glazed window shall be set in a separate frame by a gap of not less than 10mm with no rigid connection between the frames. The configuration of the double glazed window shall be further developed. Acoustic door of STC 45 rating is recommended for the Translation Booth entrance.

Zero 557/556 Zero 369

Door Sound vestibules are recommended for the entrance of the Main Hall and their locations are shown in the markup as shown in the Appendix. The vestibule should consist of one set of solid core door with perimeter acoustic seals and the other set of door to be STC 45 acoustic door. For the Multi13

Slab Thickness The slab between the floors is proposed to be a metal decking system with approximately 100 mm concrete on top. As discussed in the meeting, it is known that the installation of a floating floor to maximize the transmission of sound and vibration from the Main Hall to the below floor is not feasible although the noise intrusion to the below areas is understood not to be a serious concern. With the implementation of such metal decking system, it may result in excessive floor vibration so that the services and ceilings below will be excited with ‘feelable’ vibration. Since the services and events being held inside the Main Hall are believed to involve more dynamic movement with people moving synchronously and people jumping up and down in time with music, the floor is therefore recommended to be designed and to comply with The American Institute of Steel Construction, Steel Design Guide Series 11 – Chapter 5 Design for Rhythmic Excitation or equivalent standards. Ceiling Construction As mentioned above, since it is understood that floating floor is not feasible to be installed due to site constraint, in order to treat the impact vibration transmitted from the Main Hall to the Multi-Function Room and Meeting Rooms below, it is recommended that a sound barrier ceiling should be installed within those noise sensitive spaces underneath the Main Hall. The concept of the construction of sound barrier ceiling is shown in the figure below.

Our current assumption is that the sound level attained in the Main Hall would be between 105 – 110 dBA. With the application of sound barrier ceiling inside the Meeting Rooms, the sound level inside these Rooms would likely reach 50 dBA when heavy music is played in the Hall. In this case, the acoustic environment inside the Meeting Rooms would become unsatisfactory due to the noise intrusion from the Hall. Likewise, assuming that the acoustic and unplugged music generated inside the Multi-Function Room would reach about 90 dBA, there is a possibility that it might still be perceptible in the Main Hall which would affect its normal operation. On the other hand, there may be noise impact to the below retail shops from the Multi-Function Room when heavy music is played unless additional acoustic treatment such as a floating floor is installed in the Multi-Function Room.

Type 2 STC 55

Roof Construction It is understood that air cooled chillers, AHU and other mechanical equipments shall be installed at the roof top of the building. Since the Main Hall is located directly underneath, the sound separation shall be carefully reviewed. We will provide further recommendation when chiller noise data is available and initially it is recommended that the slab of the roof should have minimum surface weight of 480 kg/m2 to increase the acoustic integrity of the slab. The chiller ideally shall be supported near the perimeter board instead of the mid-point of the roof which has stiffness.

Type 3

Wall Construction

STC 50

3-layer drywall with insulation. Double layer of gypsum board on one side of metal studs, single layer on the other side with insulation between studs, erected from slab to slab.

The general partition constructions to help achieving the ratings mentioned in the above are described as follows: Table 2 - Partition Construction to Achieve STC Ratings Partition General Construction Type & STC Rating 4-layer drywall with insulation. Double layer of gypsum board on each side of two single rows of 75mm thick metal studs, separated by a 25mm gap, with insulation between studs. The partition shall be erected from slab to slab.

2-layer drywall with insulation. Single layer of gypsum board on each side of metal studs with insulation between studs, erected from slab to slab.

Type 4 STC 45

Type 1 STC 60 Sound Barrier Ceiling Design The sound barrier ceiling as shown above consists of 3 layers of 12mm thick gypsum boards suspended by spring isolation hangers. A minimum of 100mm thick batt insulation shall be put above the gypsum board ceiling within the void and the overall thickness is approximately 300 mm. A false ceiling shall then be installed underneath the sound barrier ceiling. One of the issues to be noted is that this acoustic treatment takes up quite a bit of headroom and full utilization of the space may be sacrificed as a result. Moreover, if the room layout is changed in the future, the sound barrier ceiling will have to be dismantled and re-constructed once again.

Revision 0

In additional to the above, the application details of drywall include the following:

1. Provide continuous acoustical (non-hardening) caulking beads on each side Option 1: 4-layer drywall with insulation. Double layer of gypsum board on each side of a single row of 100mm thick metal studs with insulation between studs, erected from slab to slab. Option 2: 150mm solid concrete block, plastered on both sides (minimum surface weight of 360 kg/m2). 14

4. Ductwork shall be located directly above the entrance instead of near

There is no "ideal" shape in a space with so many usages. From our perspective, the rectangular room shaping as currently offered is generally favorable for the Main Hall to provide lateral sound reflection to the audience. However, we would need to review if there are any side wall speakers that may create sound flutter problem between parallel walls. The side wall surfaces shall incorporate sound diffusion elements. There are many means to achieve this effect, but they all are based on the concept that the wall surface is made irregular rather than smooth finishes.

Since sound being three-dimensional in its behavior, this means that ceiling profile will need to be considered. The correct shaping of ceiling throughout the space is most important to ensure optimum sound distribution to both listeners and performer. A flat ceiling panel with proper angled is preferable to reflect sound evenly to the audience area. The angles and locations of the ceiling panels will be developed when the Hall section is available.

6. Electrical and service outlets that will be wall mounted shall avoid back-toback with minimum 600 mm apart.

Room Acoustics Discussion

Reverberation Time A multi-purpose Main Hall basically comprises of two types of activities, i.e. speech and music. Ideally, each activity requires a different type of acoustic space to maximize listening pleasure. The acoustical phenomena related to musical are more complicated and are contributed by both early and reverberant sound. The early decay sound is directly related to the room shape and reverberation time. Room reverberation gives fullness and signing tone to the music, but must not be so great as to destroy voice intelligibility.

Pipe and Duct Penetration Details

Reverberation Time (RT) is the time required for a sound to decay to inaudibility after the source has stopped. In general, a long RT (2 seconds or higher) is appropriate for traditional organ and large - scale works, 1.6 to 1.8 seconds is appropriate for chamber music or small orchestral performance, and 1.8 to 2.1 sec is suitable for symphonic music. On the other hand, low RT of around 1.0 second is satisfactory for drama. This also encompasses the optimum reverberation range for video projection, dance and amplified musical presentations. The Main Hall will be exclusively used for amplified speech and music. A suitable reverberation time would be around 1.2 second at mid frequency to ensure proper separation and blending of successive syllables or musical notes. Based on our initial calculation, the current volume and person ratio inside the Main Hall is approximately 7 cum/person. This is generally acceptable for the amplified sound condition with the proposed RT.

Materials envisioned for the interior of the Main Hall are mostly likely to be soft with sound-reflective property in the front portion to create lateral sound. All front wall and ceiling surfaces will be reflective and diffusing where feasible, with sound-absorbing materials for potentially problematic rear wall surfaces. Seating is the major element of sound absorption in the Main Hall but we understand the main floor has flexible seat arrangement. The choice of seat will be reviewed to assess their impact to the room absorption. Flooring under the seats should be carpet with thick underlayment to absorb footfall noise impact to below. Moreover, the Lobby outside the Main Hall should also be laid with full carpet. Our current assumption is that the stage floor will be timber to facilitate any cable trunk on floor. We will review the detail in the next stage to incorporate possible sound and vibration transmission break in order to reduce noise impact to below. The side walls and ceiling should be as hard (i.e. non sound-absorptive) and heavy as feasible over the audible frequency range to reflect sound to the audience. The selection of material shall be discussed when the interior design concept is developed. The following table shows the recommendation of sound absorbing materials to tune the acoustical performance of the Main Hall and other concerned spaces in order to meet the intended acoustical criteria. The materials specified in the table shall be further developed.

Cable Tray Penetration Detail for STC 50 or above partition

Revision 0

Room acoustics deals with the behavior of sound in a room as affected by the room volume, room shape and sound-absorbing properties of the room finish materials. Sound perforated panel with different thickness are used to tune the reverberation in the Main Hall in order to enhance clarity and appropriate level of bass response. This will be developed in the detail design stage.

The ambient noise of the Main Hall shall be reasonably low to ensure high intelligibility of voice and good listening condition for music. Based on our past experience of similar projects, the ambient of Main Hall with amplified sound shall meet NC 30 or better. However, given the site limitation and uncertainty of the AHU location, we suggest NC 35 to be the maximum level for the Main Hall. NC level requirements of other areas in association with this project are as follows:

The rear wall shall have 100 mm thick insulation (48 kg/m3 density) behind the perforated timber panel. Finishes for side wall to be determined, it is mostly hard surface with sound diffusive elements.

Peak noise intrusion from sources outside the Main Hall can transmit sound above the continuous background sound design goals. These criteria are determined based on the premise that exterior noise should be controlled to within NC 30 for continuous noise and peak noise below NC 40. It is our experience that peak (the nosiest) event shall be controlled to within 10 dB points above the proposed background noise level for the Main Hall space.

Small fans and other types of equipment that is less than 5 kW would require minimum vibration isolation, typically pads sized to provide static deflections in the range of 2.5mm to 7.5mm, depending on the location and rpm of the equipments.

Table 4 – Recommended Water Flow Velocities Outside Pipe Diameter (mm)

Belt Driven Fans

As an overview, all major rotating or reciprocating mechanical equipments will require spring isolation with a minimum static deflection of 25 to 50 mm, depending on equipment size, proximity to noise sensitive spaces, and the vibration structural performance of the floor slabs that support this equipment.

Sizes of pipes for maximum flow velocities are as follows: o

Furthermore, equipment with variable frequency drives (VFD) must meet these limits throughout the entire frequency range that the equipment will operate. Additional constraints on vibration isolation will be imposed for equipment on VFD operation including locking out specific operating speeds and imposing lower limits for operational speeds to avoid resonant conditions that may result in significant structural excitation of the isolated system and the supporting structures. All such provisions will be described in detail in the vibration specification.
