|Title||A Cost Estimate System for Gaza Strip Construction Contractors|
Effective estimating and tendering process is a key to the success of a construction project. The preparation of cost estimate for a project is one of the most difficult tasks in project management. Nowadays, successful cost estimating has to be based on thorough and updated information, and processed utilizing a well designed estimating software. The aim of this thesis has been to explore the local practice in construction cost estimating and develop a cost estimating system to facilitate the local estimating practice mainly in building construction. Construction cost estimating related literature has been generally reviewed; meanwhile some estimating software packages have been reviewed also. The researcher explores Microsoft Excel capabilities and tries to acquire the skills needed to utilize these capabilities in developing a cost estimating system which he names "Gaza Estimator Software" (GES). A survey questionnaire supported by personal interviews is used to explore the local practice in cost estimating. Fifty-one questionnaires are distributed to contractors of first, second, and third classes. Forty questionnaires are received and analyzed. The study shows that most of contracting companies are still estimating the projects manually. Shortage of user friendly estimating software packages and lack of available qualified personnel in using computer-based estimating systems are considered the main obstacles in using computer in construction estimating. GES is a PC-based system which has been designed to run under Microsoft Windows. Microsoft Excel is used in developing GES, as most companies in Gaza Strip are familiar with it. Full description of GES has been given with detailed implementation procedures. GES has been evaluated to test its suitability to local estimating practice. Evaluation of GES has addressed both conceptual and practical issues. One of the main recommendations of this research is to encourage local contracting companies to have an estimating software package and use it in estimating the works in order to get more accurate estimates, save time, minimize error, and hopefully to have better chance to win bids.
