SOURCING DATA FROM CLIENT :

In order to establish an accurate scope of work, we have devised a questionnaire to get all the data concerning the type of process, structural requirements, machinery layout, material handling systems, site conditions, etc. from our clients and their consultants. The process requirements are studied and modifications are suggested in the machinery layout to suit site conditions and economise on the structural grid. This reduces rework and alterations during construction and avoids Extra Items. The Architect’s active role in planning at this stage is a fundamental factor in reducing cost and time overruns.

COST ESTIMATE:

In industrial construction, the type of structure and finishes required by different types of industries are vastly different. It is therefore difficult to estimate the cost on a thumb-rule basis. Accurate quantities play a major role in arriving at an accurate estimate. As we work in CAD with 3D modeling to get accurate working drawings, we use the same model to extract key quantities with tremendous accuracy. We also calculate the project quantities manually and cross tally the results.

We have also developed our own program for calculating item rates from latest market rates. Both these factors, along with our experience in this field, ensure that our project estimates are very accurate. Most of our projects are within ±5% of estimated cost. The cost of additions made by the client during the course of the project is also estimated from time to time and contractors billed quantities with estimated quantities are compared.

USE OF DEDICATED PROGRAMMES AND DOCUMENTATION

We have developed several CAD programs in-house to speed up the processes like drawing and estimation. This helps us greatly increase drawing output and accuracy. We work directly with 3-D models of the building. We can directly output execution drawings and quantities from the models. Also rendered images give the client an accurate picture of what the plant will look like on completion. Detailed documentation of all planning meetings is kept on record for future reference.

TIME SCHEDULE:

After scrutinising the initial Bar Chart submitted by the contractor, the final Time Schedule is arrived at. The sequence of activity is checked to remove any potential bottlenecks. Certain critical Landmark completion dates such as Erection, Factory flooring, Windows fixing, etc. are identified and incorporated into the contract document. Weekly progress meetings are held jointly with the contractor and Clerk of Works to check the progress of the work. Detailed documentation is prepared right from planning to completion stage. Dovetailing of various disciplines like HVAC, Electricals, Utility Planning is envisages and planned for. Minutes of meeting are distributed to all concerned parties for timely action.

QUALITY ASSURANCE:

A major factor contributing to use of good quality material in construction is the Item Specifications in the tender and contract. Over the years we have updated our Specifications to include latest available materials and technology. Accuracy in terms of gauge, make, quality, model, etc. ensures quality construction and helps the contractor to quote accurately.

All material brought to the site are inspected visually and the source verified. Cement and steel is sent lot wise to independent Material Testing Laboratories. Samples of concrete mix poured on site are also sent for testing. Provisions for removing defective workmanship is incorporated in the contract. 2.5% Retention amount is withheld for the Defect Liability Period of one year. A 10-year guaranty for all waterproofing is taken on Stamp Paper for additional protection.

CLERK OF WORKS :

In order to monitor activities on a day to day basis, and also have greater supervision on quality, it is advisable to appoint a senior Civil Engineer as clerk-of-works for the duration of the construction. His interaction with the various consultants can ensure an overall perspective of the project and avoid bottlenecking of different activities. His presence also ensures reduction in response time to problems faced at site. With increasing demand to reduce construction time and start returns on investment as soon as possible, we must use these methods to speed up, monitor the construction activity, and at the same time, ensure quality.
