Conference Proceeding
AHIAGA-DAGBUI, D.D. and SMITH, S.D. 2014. Exploring escalation of commitment in construction project management: case study of the Scottish Parliament project. In Raiden, A. and Aboagye-Nimo, E. (eds.) Proceedings of the 30th Association of Researchers in Construction Management (ARCOM) annual conference, 1-3 September 2014, Portsmouth, UK. Reading: ARCOM [online], pages 753-762. Available from: http://www.arcom.ac.uk/...Ahiaga-Dagbui_Smith.pdf

Successfully managing large construction projects within defined budget and time constraints has always been a major challenge largely because crucial decisions about the project's ultimate fate have to be made within an environment of significant un...

Dealing with construction cost overruns using data mining. (2014)
Journal Article
AHIAGA-DAGBUI, D.D. and SMITH, S.D., 2014. Dealing with construction cost overruns using data mining. Construction management and economics [online], 32(7-8), pages 682-694. Available from: https://doi.org/10.1080/01446193.2014.933854

One of the main aims of any construction client is to procure a project within the limits of a predefined budget. However, most construction projects routinely overrun their cost estimates. Existing theories on construction cost overrun suggest a num... Read More about Dealing with construction cost overruns using data mining..

Mapping relational efficiency in neuro-fuzzy hybrid cost models. (2014)
Conference Proceeding
TOKEDE, O., AHIAGA-DAGBUI, D., SMITH, S. and WAMUZIRI, S. 2014. Mapping relational efficiency in neuro-fuzzy hybrid cost models. In Castro-Lacouture, D., Irizarry, J. and Ashuri, B. (eds.) Proceedings of the 2014 Construction research congress: construction in a global network, 19-21 May 2014, Atlanta, USA. Reston, VA: ASCE [online], pages 1458-1467. Available from: https://doi.org/10.1061/9780784413517.149

Significant improvements are achievable in the accuracy of cost estimates if cost models adequately incorporate issues of flexibility and uncertainty. This study evaluates the relational efficiencies of the fuzzy composition operators “ the max-min a... Read More about Mapping relational efficiency in neuro-fuzzy hybrid cost models..

Rethinking construction cost overruns: cognition, learning and estimation. (2014)
Journal Article
AHIAGA-DAGBUI, D.D. and SMITH, S.D. 2014. Rethinking construction cost overruns: cognition, learning and estimation. Journal of financial management of property and construction, 19(1), pp. 38-54. Available from: https://doi.org/10.1108/JFMPC-06-2013-0027

Purpose: Drawing on mainstream arguments in the literature, the paper presents a coherent and holistic view on the causes of cost growth, and the dynamics between cognitive dispositions, learning and estimation. A cost prediction model has also been... Read More about Rethinking construction cost overruns: cognition, learning and estimation..
