Construction

The quantity surveyor is responsible for preparing estimates of building cost, preparing the Bill of Quantities (i.e. a measured specification of materials and work to enable the contractor to submit a price) and, during construction, for preparing valuations of work (usually monthly) upon which the architect issues the ‘interim’ and ‘final’ certificates. The quantity surveyor should be appointed as early as possible within the development process to advise on cost management and the merits of alternative forms of construction (e.g. steel frame or concrete frame). They should also provide estimated cash-flows of the building contract expenditure. The quantity surveyor reports on the cost of construction and measures actual payments against the estimated cash-flow. Their role is to explain why the actual cash-flow differs from the original estimate and prepare revised estimates for the remainder of the project. The quantity surveyor is also responsible for estimating the cost of any possible variations in design so the development team can decide whether or not they should be undertaken.
The future of BIM and big data in quantity surveying

Cost control: The focus of quantity surveyors’ work shifts from cost estimate to cost control during the construction stage. To ensure the expenditure is within the budget limit, quantity surveyors will regularly check upon site construction progress and prepare monthly valuations and cost reporting. The BIM could provide a quick cost checking to ensure all items are captured and process in progress. The quantity surveyors are also the key coordinators between the main contractor, the principal agent, and the client to settle the interim payment. When the cost information is associated with each BIM component, once the BIM model is updated, the cost plans can be easily updated with the associated changes and variations.

The quantity surveyor (QS), as part of the design team, has many names, such as cost engineer, building economist, cost manager and construction accountant (PMI, 2013). Primarily, the quantity surveyor is the project cost consultant, and the adviser to the client and other members of the project team on matters relating to procurement and the contract. During the pre-contract stage, the QS will assist the client and project manager in providing advice on procurement routes, advising on the setting of budgets, preparation and development of preliminary cost plan and tender documentation, as well as receiving and analysing tenders and making recommendations for approval.
Knowledge, skills and functionalities requirements for quantity surveyors in building information modelling (BIM) work environment: an international Delphi study

Domain-specific functionalities of BIM are either inherent in BIM or attached to the BIM as independent expert applications (Volk, Stengel, & Schultmann, 2014). It involves using the BIM data to perform various tasks such as auto-quantity take off, structural analysis, clash detection, space management, etc. The functionalities identified for quantity surveyors are auto-quantity generation, schedule of quantities, cost checking and planning, estimation, contract documentation, whole life cycle costing and bill of quantities preparation. These are some of the applications that quantity surveyors should be able to perform using the BIM data/information more efficiently as compared to the traditional approach.
