Tendering Process Improvement With Prototype Design Implementation

Abstract

Failure of projects due to over budgeting, variations and claims as well as delays in the project time line is common in construction industry. This issue is critical, and it needs to be searched in detail for a sustainable solution. One of the main reasons of over budgeting and delays was found to be the undefined scope of the project due to the missing design at the tender stage, the ambiguous and unclear design scope of the project. This forces the tenderers to bid high rates to cover the risk of undefined design scope. The repetition of project design for the buildings with same functionality can easily be applied at different geological locations. This factor can be controlled and eliminated with the introduction of a prototype design model according to the required functionality and concerned polices. The prototype shall be prepared with full consensus of all concerned stakeholders and one of the most effective and efficient existing building of the concerned end user shall be taken as a baseline for the establishment of best possible prototype design models, which shall be applied to all buildings of the same end user anywhere across the state of Qatar. To study the impact of prototype design model implementation on the tendering process, one project is taken as a case study and a prototype design model has been implemented to the existing tendering process. With the implementation of prototype design model to the tendering process, it was found that a 40.7% saving is done in overall budgeted cost of the project, 39.0% project time is reduced and about 34% of resources were saved, which seems to be a great achievement in solution of the problem.
