Here is the abstract of a paper I presented at the 2008 COBRA Conference in Dublin, Ireland on 21 September 2008:

A case study on the tendering process and cost/time performance of a public building project in Ghana is conducted. Competitive bids submitted by five contractors for the project, in which contractors were required to prepare their own quantities, were analyzed to compare differences in their pricing levels and risk/requirement perceptions. Queries sent to the consultants at the tender stage were also analyzed to identify the significant areas of concern to contractors in relation to the tender documentation. The five bidding prices were significantly different. The queries submitted for clarifications were significantly different, although a few were similar. Using a before-and-after experiment, the expected cost/time estimate at the start of the project was compared to the actual cost/time values, i.e. what happened in the actual construction phase. The analysis showed that the project exceeded its expected cost by 18% and its planned time by 210%. Variations and inadequate design were the major reasons. Following an exploration of these issues, an alternative tendering mechanism is recommended to clients. A shift away from the conventional approach of awarding work based on price, and serious consideration of alternative procurement routes can help clients in Ghana obtain better value for money on their projects.
Keywords: case study, contractor bidding, Ghana, project performance, tendering process.

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.
