Developing a Draft Schedule Using Templates and Rules

The effort required for the initial drafting of a plan is often a real barrier to developing a useful and high quality schedule for a construction project. The goal of this paper is to demonstrate how an expert system with an editable rule base can be combined with standard templates of modifiable, predefined knowledge within a project management system in order to generate draft schedules based on limited user input. The user can capitalize on past experience by creating a template for each recurring project type. The knowledge contained in the templates is broken down into a physical view (i.e., what is being built), a process view (i.e., how it will be built), and rules for scaling the templates and computing durations based on user input. The physical view is a hierarchical breakdown structure of components that describes (without quantifying) the physical and spatial characteristics of the project type. The process view contains a list of typical activities and the logic relationships that describe their sequencing. The rules serve to link and then expand the two views in order to generate a draft schedule for the project-at-hand once its scale is specified. The feasibility and capabilities of the proposed approach are demonstrated in the context of a full-sized project composed of three buildings.

Construction Coordination Activities: What Is Important and What Consumes Time

Coordination is an important function in the building process. Recent research has shown that poor or inadequate coordination is the best that is achieved on construction sites. Nevertheless, many authors of textbooks on construction project management have not discussed this vital topic. A literature review carried out in this present study revealed that there is a lack of formal understanding on how day-to-day coordination is actually achieved on a construction project. This research was directed at identifying what activities are performed to achieve coordination and, which among those are the most important and more time-consuming for a construction coordinator. In the absence of previous research, texts on the duties and responsibilities of project managers, clerks of works, construction engineers, etc., were reviewed from the contractor's project manager's perspective during the building phase of a construction project, and an array of issues relevant to achieving coordination were identified. Initially, the array included 64 coordination issues; a questionnaire was developed for construction project managers to indicate the relative importance and time consumed on a 3 point scale (i.e., high, mid or low). Thirty-three responses received from practitioners in the Hong Kong and Singapore construction industries indicate that identifying strategic activities and potential delays and ensuring the timeliness of all work are the most important activities. Conducting regular meetings and project reviews and analyzing the project performance, detecting variances and dealing with their effects (16th and 17th, respectively in order of importance) appear to be the most time-consuming activities.     

Conjoining MMAS to GA to Solve Construction Site Layout Planning Problem

An optimal construction site layout planning (CSLP) is vital for project management. It can reduce the transportation flows and thus the costs of a project. Genetic algorithm (GA) is the most used algorithm to solve site layout problems, but randomly generated initial population in GA will decrease solution quality. Max-min ant system (MMAS) can offer a better initial population than the randomly generated initial population at the beginning of GA. In this study, a modified GA (MMAS-GA) formed by conjoining MMAS to the step of initialization of GA is proposed to solve CSLP problems. In order to reveal the computational capability of MMAS-GA to solve CSLP problems, the results of MMAS-GA and traditional GA are compared by solving an equal-area CSLP problem. The results showed that the proposed MMAS-GA algorithm provided a better optimal solution under the objective function of minimizing the transportation flows between the site facilities. The proposed MMAS-GA algorithm could assist project managers and planners to design optimal construction site layout, and thus to reduce construction costs.
