The first part represented the group assessment, while the second part assessed the overall performance. A two-part weighted fuzzy logic model was then developed to measure the CCA performance. The collected data were analyzed for normality, reliability, and intergroup differences. An online questionnaire was used to rate the importance of each factor and group, and 223 responses were collected. The proposed model contains 93 key factors and 11 project management process groups related to contract administration performance. To this end, this paper covers the development of a new multidimensional fuzzy model to quantify the performance of construction contract administration (CCA) processes at the project level. The success of a project depends on the importance of investigating the impact of contract administration implementation parameters such as response time, approval process, resolving issues, coordination, and documentation. | Department of Quantity Surveying, University of Benin (UNIBEN), Benin City, Nigeria. It is recommended that a contractor in FIDIC-based contract should get retention bond in lieu of deduction of retention money to enhance its liquidity.
It would take a contractor in FIDIC-based contract a longer time for maturity of final payment than in JCT-based contract. Interim valuation in FIDIC allows the contractor to make claims for delayed issuance of interim certificate but FIDIC does not give the contractor such right because all application for payments must be made by the contractor to the engineer.
Disbursement and amortization of Advance payment in FIDIC are more secured than JCT. The methodology comprises: (i) critical examination of payment provisions, (ii) scenario building of problem situations, (iii) assessing the sensitivity of the provisions to contractual conflict, and (iv) evaluating the effect on construction cost administration. The selected payment provisions were advance payment, interim valuation, retention and final payment. This exploratory overview examined residual risks associated with payment provisions in Federation Internationale Des Ingenieurs-Consiels (FIDIC) and Joint Contracts Tribunal (JCT) conditions of contract in Nigerian construction industry. Like in all human engagements, risk is inevitable in construction contracts. The obligee and obligor of all cost-related commitments in construction contracts are governed by the conditions of contract. New features are clause 13.2 on value engineering and clause 20 on the impartial dispute adjudication board. Second, the clauses which contain events that justify claims are spread out over the whole contract and not contained in comprehensive lists of events. First, only the 1999 Red Book contains strict time bars. There are two striking differences from the contract JCT SBC 2005 regarding claims of the contractor. Whether he has to act for the employer or whether he has to make a fair determination depends on the matter in question. A typical feature of the 1999 Red Book is the role of the engineer. The contract features general and particular conditions, the latter of which have to be drafted by the parties before the contract is entered into. The 1999 Red Book is for use when the contractor has been given the design by the employer. The paper is addressed to construction professionals who already have an understanding of English construction contracts but have not yet looked into Fidic contracts. The paper describes the main features of the 1999 edition of Fidic's Red Book, possibly the most commonly used standard-form construction contract in international projects.
