Assessment and evaluation of contractor data against client goals using PERT approach

Abstract

A methodology for assessing and evaluating contractor data for the purpose of prequalification and bid evaluation is presented. The PERT approach is used to develop a linear model for the assessment of contractor data. The model incorporates a multiple ratings permitting the uncertainty in contractor data to be evaluated. An empirical study investigating the importance of different contractor criteria is described. A lexicographical ordering with aspiration levels and risk analysis with sensitivity methods are used to evaluate and select or rank-order contractors against the main client goals of time, cost, and quality. A literature review is reported regarding client goals and current evaluation strategies. The assumptions, advantages and disadvantages of this work as well as an example are also presented.Prequalification, Bid Evaluation, Pert, Criteria, Client Goals, Contractor, Data,

Multi‐attribute Contractors Ranking Method by Applying Ordering of Feasible Alternatives of Solutions in Terms of Preferability Technique / Daugiatikslis Rangovų Parinkimo Metodas Taikant Įmanomų Sprendinių Alternatyvų Rangavimo Prioriteto Požiūriu Būdą

“…According to Hatush and Skitmore (1997) and Holt (1996), the information used for the assessment of parameters for pre-qualification falls into the following groups:…”

Multi‐objective Contractor's Ranking by Applying the Moora Method

“…The contractor pre-qualifi cation process involves the establishment of a standard for measuring and assessing the capabilities of potential contractors (Ng et al 1999). The information used for the assessment of parameters for prequalifi cation should fall into several groups (Hatush and Skitmore 1997). Jaselskis and Russel (1992) have identifi ed commonly used attributes for pre-qualifi cation and bid evaluation and have proposed methodologies for contractor selection.…”

A Group Decision-Making Aggregation Model for Contractor Selection in Large Scale Construction Projects Based on Two-Stage Partial Least Squares (PLS) Path Modeling

“…This section mainly covers two topics: the applicability and advantages of the typical PLS path modeling based on multiple-table analysis and the two-stage PLS path modeling based on multiple-table analysis, with an algorithm for the new method.

“…Normally, for a lump-sum contract, a total price is considered for a specific bill of quantities, while a cost reimbursement contract can be more attractive to the owner if the quoted price is reasonably low. (3) Technological capacity (Dickson 1966;Hatush and Skitmore 1997;Alsugair 1999;Ng and Skitmore 2001;Lai et al 2004;Watt et al 2009Watt et al , 2010. The contractor must demonstrate that it has the technical capacity to perform all activities required by a specific project.…”
