Cost Engineering of Mid-rise Timber Buildings

Technical Design Guide 51
WS TDG 51 Cost Engineering of Mid-rise Timber Buildings Cover
This Technical Design Guide provides reference data and methodology advice for cost engineering activities directly and indirectly associated with the design, procurement and installation of wood structures in Australia, especially with reference to mid-rise buildings (four or more levels).

Introduction

This guide identifies and explains the typical differences between the costing of wood-based projects with respect to those using other systems, as described by the six main categories shown in Figure 1.2. Drawing on examples from a database of relevant completed projects, the text discusses several considerations under each category of difference, suggesting how they may be best measured and allowed for. Table 1.1 summarises what these differences have typically been shown to include.

While many detailed guides have been published on the design and maintenance of timber structures, there has been relatively little focus on the specifics of costing and ultimately building them. This guide has been prepared to address the specific cost-related knowledge and approach that needs to be considered throughout the development process, with respect to the Australian Cost Management Manual and other relevant publications.
