Cheng, M-Y (1992) Automated site layout of temporary construction facilities using geographic information systems (GIS). PhD thesis, University of Texas at Austin, USA.
Abstract
This research endeavor focuses on developing an automated site layout system for temporary construction facilities. The site layout of temporary facilities (TF) is an important preplanning task that can either enhance or adversely affect construction productivity. An efficient TF layout can significantly reduce construction conflicts and improve project efficiency. In this research, the system, ArcSite, was developed to assist the project manager in identifying suitable areas to locate TFs. ArcSite is comprised of a Geographic Information System (GIS) integrated with a database management system (DBMS). The system includes the knowledge specific to construction site layout, TF databases, Arc/Info databases, and GIS geoprocessing system. In the development of the system, industry rules of thumb and the state of the art in layout modeling were reviewed and compiled in a systematic form. ArcSite uses the concept of Searching by Elimination to generate the potential sites for each TF. A heuristic algorithm was developed to model the process of human decision-making and to identify the spatial relationships between the different data layers which represent the site geographies. Through both qualitative and quantitative modeling of facility relationships, an objective function for calculating the Proximity Index (PI) was used to determine the optimal site of each TF. The primary features of the system are as follows: (1) integrate construction schedule and design information to lay out TFs for both short term and long term usage, (2) allow for the use of the PF as the TF and reallocation of space over time, (3) automatically generate potential sites for each TF, (4) identify optimal site, and (5) locate the TF within the optimal site. ArcSite improves the site planning efficiency by integrating spatial and thematic information into a single environment. Also, compared with current methods, ArcSite significantly improves the computational effort and increases the data accuracy and consistency. Therefore, this study achieves the goal of developing an automated information system to enhance the TF layout design.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
