Abstract: Contractor prequalification involves the screening of contractors by a project owner to determine their competence to complete the project on time, within budget, and to expected quality standards. The process of ...

Abstract: Steel silos are widespread around the world, and are used for storing different materials, including cement, fertilizers, grains, and raw materials. Building a new silo provides a fairly big storage capacity within a short ...

Abstract: Expeditious repair of the unpredicted breakdown of the systems components of facilities is a crucial demand that is highly conducive to the convenience of users and to the longevity of systems. The determination of maintenance ...

Abstract: Recently, the construction industry has introduced fundamental changes for integration of functions during the different project phases. The design/build approach that integrates design and construction is a prominent ...

Abstract: Precedence-preserving crossover and mutation operators for scheduling problems with activities’ start times encoding are proposed and employed in this paper. The objective is to tackle the incapability of the genetic ...

Abstract: A strength Pareto evolutionary algorithm (SPEA) is proposed and was modified by incorporating logic-preserving crossover and mutation operators and employed to devise a set of optimum finance-based schedules of multiple ...

Abstract: Construction contractors often finance projects using bank credit lines that allow contractors to withdraw money up to certain credit limits. Finance-based scheduling provides schedules that ensure that the contractor’s ...

Abstract: Contractor’s ability to procure cash to carry out construction operations represents a crucial factor to run profitable business. Bank overdrafts have always been the major source to finance construction projects. However, ...

Abstract: Problems in operating construction equipment in Egypt were perceived as resulting in low productivity. Productivity was considered in this study as a measurement dimension that sufficiently describes operator's performance. ...

Abstract: Construction scheduling is the process of devising schemes for sequencing activities. A realistic schedule fulfills the real concerns of users, thus minimizing the chances of schedule failure. The minimization of total ...
