An approach for enhancing the production efficiency of bill of quantities (BQ) used on construction projects is presented. The approach was developed to integrate the quantities obtained from a building information model of the project into a suitably prepared electronic format of BQ with 3D views. In this format of BQ, the building information modeling (BIM) technology provides enhanced functionality to a contractor’s quantity surveyor whose primary task is to accurately determine the quantities from the project drawings. A review of the traditional BQ preparation methods is presented to highlight their characteristics and to reflect on their benefits and barriers. Questionnaire surveys were conducted with various groups of respondents to obtain their opinions about the proposed BQ format. They included experienced quantity surveyors from the public and the private sectors, postgraduate, and undergraduate students studying in BIM-related courses. The results of the questionnaire survey showed mostly a positive view toward the proposed BQ format. Slight differences in the opinions of these three groups were also present. It is expected that the approach as presented in this paper for the development of BQ with 3D BIM views could usefully be incorporated into the standard quantity surveying practices for quantity takeoffs in various countries.

An understanding of how the design and construction processes interact to determine the cost and quality of buildings is essential to architects, builders and surveyors. Design and the Economics of Building is a text for students in all the built environment fields. It takes a fresh approach to the important issues involved in the building process and their relationship to each other, dealing among other topics with: the cost and construction implications of design decisions; the way design affects, and is affected by, the construction process; the economics of building's essential resources - labour, materials, technology and management; the cost of energy efficiency; methods of cost prediction and control; procurement systems and their implications for cost, time and quality; information flow between designers, surveyors and contractors; the value of buildings, determined by market and social criteria. With its wide scope, readability and generous use of examples and references to recent projects, Design and the Economics of Building will be of interest to all those concerned with the built environment as well as being an essential text for architecture, surveying and construction management students.
