Johannesburg, Guateng, South Africa
I am a Senior Lecturer in the School of Construction Economics and Management at University of the Witwatersrand, South Africa. In the past, I have been a Lecturer in the School of Construction Management and Engineering at the University of Reading, UK (2010-12); and also a Post-Doctoral Academic Fellow (2009) and Graduate Teaching Assistant (2008). I completed my PhD at University of Reading in Dec 2008 on the relationship between risk and price in tendering. Prior to transferring to Reading in Jan 2008, I was an MPhil/PhD student at KNUST, Ghana (2004-07). I gained my undergraduate degree in Building Technology from Kwame Nkrumah University of Science and Technology (KNUST), Ghana in 1998-2002. During school days, my peers elected me to serve in several leadership positions including SRC President at KNUST. From 1994-96, I attended Suhum Sec. Tech. School after basic education at schools in Ghana and Nigeria. I did my National Service with the Fanteakwa District Assembly in 2002-03. After that, I worked at the Development Office of KNUST until I started my PhD in 2004. I am a co-organiser for the WABER Conference and an author of 30+ research publications.

Abstract
Formal and analytical risk models prescribe how risk should be incorporated in construction bids. However, the actual process of how contractors and their clients negotiate and agree on price is complex, and not clearly articulated in the literature. Using participant observation, the entire tender process was shadowed in two leading UK construction firms. This was compared to propositions in analytical models and significant differences were found. 670 hours of work observed in both firms revealed three stages of the bidding process. Bidding activities were categorized and their extent estimated as deskwork (32%), calculations (19%), meetings (14%), documents (13%), off-days (11%), conversations (7%), correspondence (3%) and travel (1%). Risk allowances of 1-2% were priced in some bids and three tiers of risk apportionment in bids were identified. However, priced risks may sometimes be excluded from the final bidding price to enhance competitiveness. Thus, although risk apportionment affects a contractor’s pricing strategy, other complex, microeconomic factors also affect price. Instead of pricing in contingencies, risk was priced mostly through contractual rather than price mechanisms, to reflect commercial imperatives. The findings explain why some assumptions underpinning analytical models may not be sustainable in practice and why what actually happens in practice is important for those who seek to model the pricing of construction bids.
