Abstract
This dissertation presents a framework on the incorporation of spatial and temporal attributes of Construction Requirements in construction workflow planning and scheduling. The term 'Construction Requirements Driven Planning and Scheduling' is coined to emphasize the importance of early construction input in planning the construction sequence via Construction Requirements which represent the key preconditions for construction The knowledge embodied in the construction requirement serves as a sequencing rationale, as well as a tool for analysis of the construction requirement. The key contributions of this work include the formalisation of the construction requirement taxonomy based on identified core characteristics, which embody the temporal, spatial and abstract attributes, and the interactions between them. A spatial modelling and analysis framework incorporating four-dimensional computer-aided design for detecting conflict and congestion in construction workspaces is proposed. This framework is based on spatial demand and supply, and captures the utilization of space from this perspective. The temporal aspects of the construction requirements are represented using a proposed modelling framework, PDM++. This allows the capture of static and dynamic requirements, complex temporal constraints and hierarchical modelling of plans. Finally, a multi-objective genetic algorithm is used to resolve both spatial and temporal aspects of the construction requirement, with case studies demonstrating the validity of the approach.

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
