What Is Construction Site Management ? 



Managing the design and construction of a stated project to achieve an architectural and construction program at the lowest beneficial cost to owner within reasonable profit framework for the participants. Integration of various independent factions through planning,

Why It Exists ?   



 

Inflation Better project control Use of sophisticated management technique Construction knowledge during design Control of cost Team effort instead of competition

Importance 

Defines the scope of work



Basis of project operation



Yard stick for measuring progress and evaluating resources

Objectives 

 

 

Time completion required within a certain time Cost-expected project cost versus benefits will enable reward or profit to be made Quality completion is required Performance project performance

Factors      

Cost Complexity Size Time Experience Safety

Different Approaches



Design –assembled approach



Segregated approach

Design-assembled Approach 







Divides the work according to design and phases Further gets divided into documentation packages Assign contractor for each package of work Role of manager: co-ordinate bid packages and evaluate each contractor’s responsibility

Segregated Approach 





Divides the work according to established subcontract divisions Selecting the contractor as per their specialty of work to requirement of design Role of manager: oversee the work of subcontractors and suppliers

Stages Of Activities          

Survey and layout Clear site Driving piles Excavation for foundations Foundation works Masonry partitions Ceiling works Piping systems Flooring and Roofing Tiling, plastering and painting

Cost Estimates At Different Phases And Their Accuracy

Project Control WHAT IS PROJECT CONTROL ? The Project Control System aims at ensuring the execution of work as per the planned schedule and application of necessary corrective measures, including RE-PLANNING, to achieve the project objectives.

PROJECT CONTROL PROCESS     

PROJECT CONTROL PROCESS. CONTROLLING RESOURCE PRODUCTIVITY. CONTROLLING COST. CONTROLLING TIME. PROJECT MANAGEMENT INFORMATION SYSTEM.

Importance Of Controlling 

CONTROLLING BENEFITS 

Operational control benefits



Administrative control benefits



Directional control benefits.



Strategic control benefits.

The Project Plan Controls The Project By: 

Breaking a complex process down into a number of simpler components



Providing visibility for obscure or ambiguous tasks in the project



Providing a single point of reference for everyone

Contd… 

Enforcing scrutiny of the sequence and nature of events



Providing a baseline against which execution of the project can be compared



Anticipating likely events and providing pre-planned means of

Controlling And Monitoring        

The Cost Control System The Project Budget Control of Project Cash Flows Schedule Control Schedule and Budget Updates Organizing for Quality and Safety Work and Material Specifications Total Quality Control

Cost Control System Should Have Least Response Time Therefore Enabling Quick Monitoring And Prompt Decisions Based On Simple Cost Reports Initiated At Regular Frequency By Cost Incurring Centres And Monthly Cost Reports Compiled By Cost Accountant. For Effective Implementation,as Far As Feasible,cost Control System Should Be Easy To Understand,simple To Implement Without Creating Inter-departmental Or Inter-personal Conflicts Methods Are  Profit and loss accounting method.  Standard costing method.  PERT And CPM method.

Time- Cost Relationship Project time and cost are inter-related. Project time corresponding to the minimum value of the cost function gives the most economical duration of the project. The project cost curve also gives the minimum cost of reducing the project duration from its optimum (economical) completion time

Controlling Resource Productivity Here, the causes of wastage are located by analyzing variances and efficiency of planned and on site productivity. Productivity performance variance = Planned productivity – Actual productivity Productivity performance index = Planned productivity Actual productivity

Controlling Resource Productivity Methodology for controlling resource productivity is divided into 4 stages:  Defining the control purpose  Measuring actual performance,  Computing productivity performance variance,  Identifying their causes for affecting improvements.

PMIS Is An Integrated User Machine System That Provides Information To Support Operations, Management And Decision Making Functions, Relative To Planning And Control Of Project Objectives.

Contd… Main Functions:  To Report Correct And Necessary Information In A Form Which Can Best Be Interpreted By Management And At A Level Of Detail, Most Appropriate For Individual Managers Who Will Be Using It.  To Organize Efficient Means Of Measuring, Collecting, Verifying And Quantifying Data Reflecting Performance With Respect To Time, Cost, Resources And Quality.  To Manage Means Of Converting Data From Operations To Information.  To Deliver Information On Time For Consideration And Decision Making For Remedial Corrective Action.

Safety 







Manager should review the safety program of each contractor Should assign safety manger at site Signboards, signals, safety equipments should be installed Should spread importance of safety among workers.

Conclusion 

It has not only incorporated modern management techniques and advance construction controls, but also works within framework of today’s construction industry by retaining the specialized activities of design professional and contractor under control.
