Once selected, the frame material is unlikely to change, as to do so can have significant programme implications from the consequential impact on the design of other major elements, such as cladding, service installations etc.
STEEL STRUCTURE BUILDING ESTIMATE SERIES
This has been developed further with information from a series of articles written by AECOM, also published in Building Magazine, from 2017 onwards.Ĭomplex service routing through and between steel beamsįor most projects, the decision on the frame material choice and form happens early in the design process, often on the basis of early design principles, limited information and budget costings.
The information presented here is based on a series of articles written by Gardiner & Theobald LLP, and published in Building Magazine from October 2011 to October 2016. Through the identification of the key factors relevant to each project and the adjustment of typical rates accordingly, the accuracy of budget structural steel estimating can be significantly improved.
STEEL STRUCTURE BUILDING ESTIMATE DRIVERS
This article outlines a number of key cost drivers that must be considered in order to make steel frame rates project specific, and provides guidance on current cost ranges for different building types and locations. This selection should be based on project specific costings, and the challenge to the cost consultant is to recognise and reconcile fluctuations in material prices in relation to returned tender price data all in the context of limited available design information during early estimates. Cost is a fundamental consideration in the selection of structural frame material and form, which is a key early decision in the design process.
