Searching for value: construction strategy exploration and linear planning

Abstract

Examined is how contractor or construction manager decision making and judgment in response to client objectives and project constraints can be aided by a structured approach to construction strategy selection and assessment using time-space project process and product modelling. The context studied is one of high-rise construction. Construction strategy is expressed in terms of strategy modes and tactical variables and accompanying values, which in turn are expressed in terms of a formal plan using a linear planning modelling paradigm. Highlighted is the important role that data visualization can play in both formulating strategy and assessing its workability via the medium of linear planning graphics complemented with other data representations that make use of quantitative product model data. Of particular interest is the ability to formulate and assess alternative construction strategies in a relatively fast and cost effective manner in order to achieve best value as a function of project constraints, context, and project participant objectives. Included in the assessment task is consideration of the impact of strategy on construction process productivity and production rates by way of performance metrics that relate directly to strategy workability. The concepts presented are illustrated through their application to a large-scale, mixed-use project.
