|Title||Valuation of Unbalanced Bids in Construction Projects in the Gaza Strip|
|Title in Arabic||تقييم العطاءات الغير متوازنة في مشاريع البناء في قطاع غزة|
The construction sector is considered as the most important sectors in the Gaza Strip. The procurement stage including the process of analysis and evaluation of the bids considered as the most important stages in the project life cycle. The implementing company will be selected in this stage. The selection of the implementing company will be important factor for the success or the failure of the project in terms of time, quality and cost. The aim of this study is to improve the capacity of owner institutions in the evaluation and analysis of bids in order to discover the unbalanced bids. In addition to prevent unbalanced bid occurrence in the future. The aim of this study was achieved by reviewing previous studies regarding the definition, analysis and evaluation of unbalanced bids. Also how to detect and deal with unbalanced bids. Structured interviews with ten experts working in the field of project management and procurement were done. The interviews targeted several issues related to unbalanced bids. The results obtained from interviews with experts were used to formulate a mathematical model to analyze and evaluate the balanced / unbalanced bid. Two main reasons have been identified for the occurrence of unbalanced bids. Frontloading and increasing prices of items expected to increase quantities during the implementation of the project, or vice versa. A number of references to compare prices have been studied, such as (prices estimated by owner’s engineers – bidder’s average prices – prices monitoring sheets). The allowable difference ratios from the prices references were determined during the study. The proposed MS excel mathematical model would enable workers in the field of contracts evaluation to determine whether the bid is balanced or unbalanced and then selecting the appropriate bid to achieve the institution requirements. The study recommended owners institutions working in the construction sector in the Gaza Strip to insert a special clause for unbalanced bids in the tender documents. The study also recommended to develop a written method and procedure for the analysis and evaluation of unbalanced bids. Finally to prepare legal clauses to be insert in tender documents to deal with the causes where unbalanced bid occurred.
