This paper reports theresearch findings into pricing for risk incompetitive tenders by constructioncontractors. The research is based onstructured interviews with 10 contractingpersonnel; supplemented by 23 responses ofconstruction personnel from an online survey.Two common methods to price for risk are atrade-by-trade basis or an overall percentageor lump sum addition to the base estimate.Experience and intuition plays a significant rolein pricing for risk in tenders and the numberand type of people involved varies with projectsize, with greater involvement as project sizeincreases. The most significant risks priced intenders were: availability of resources; designor documentation errors; incomplete design;buildability issues; and inclement weather. Themost significant project factors considered bycontractors when pricing for risk in tenders are:value of liquidated damages; type ofcontract/procurement; completeness ofdocumentation; project complexity; and currentworkload. These risks and project factors areprimarily those over which the contractor haslimited or no control.
