Liverpool John Moores University, School of the Built Environment, Liverpool, UK Department of Civil Engineering, University of Nebraska, 126 Nebraska Hall, Lincoln NE 68503, USA Not until recently, the establishment of a whole life cycle budget for a constructed facility largely depended on the initiative of using the standard method of measurements (SMM) structural approach to the development of a cost or budget plan. This method, argues the RICS (2009), “created inconsistency in measurement and descriptions, resulting in the production of unclear basis for the estimates”. The constraints associated with traditional cost planning and estimating tend to be compounded by the complexity associated with the deployment of building information model (BIM) technology that is pertinent to the achievement of whole life cycle cost management of a constructed facility. This research is aimed at exploring the impact of the new rules of measurement on the building information model schema pertinent to the quantity surveying practice on construction based projects. The research presumes that even though the new rules of measurement are not mandatory, they are likely to influence cost planning and estimating practice because they have been developed with a view to setting “the best practice” in the development of cost plans. The likely impact could subsequently affect the current building information model schema for cost management. Keywords: building information model, cost planning, quantity surveying, standard method of measurement.

INTRODUCTION
The cost planning process arose out of the need to plan effectively the cost of a construction project from inception through design and continuing throughout the construction phase (Corbett and Rowley, 1999). Because of financial constraints that were triggered by the war, the Ministry of Education developed cost limits with a priority to stabilize school building costs (Ashworth, 2004). Even with the advent of more modern procurement strategies such as prime contracting and public private partnerships (PPP), the necessity of a sound cost plan does not appear to diminish (Kirkham, 2007). Managerial Auditing Journal (2004) stated that “the need for effective cost planning has become increasing important following the recession in the late 2000s”. With an increased use of a cost plan, Kirkham (2007) found that there has been a swift increase in the use of Information Technology (IT)-supported cost

planning systems; that emphasize the continuous evolution of the cost plan in tandem with the design evolution (Best and Valence, 2002). However, the constraints associated with traditional cost planning and estimating tend to be compounded by the complexity associated with the deployment of IT, let alone that of building information modelling (BIM) technology that is pertinent to the achievement of whole life cycle cost management of a constructed facility. This research was aimed at exploring the impact of the new rules of measurement on the building information model schema pertinent to the quantity surveying practice on construction based projects.

RATIONALE FOR THE RESEARCH
The current cost planning process has been found to be inconsistent, inaccurate and providing a poor cost management service to the architecture, engineering, construction and facilities management (AEC/FM) industry (RICS, 2009)....
