Abstract
Pre-tender cost estimates of construction projects require extensive knowledge and
expertise. The aim of this paper is to identify, evaluate and rank essential factors affecting the
accuracy of pre-tender cost estimating from the perspective of clients and consultants. A
survey questionnaire was conducted to elicit professionals' views on and experiences with
factors affecting the accuracy of pre-tender cost estimates; a total of 70 organisations (i.e.,
46 clients and 24 consultants operating in the Gaza Strip, Palestine) responded to the survey.
The results of analysing a total of 64 factors considered in the questionnaire reveal that the
top five factors affecting the accuracy of pre-tender cost estimating are (1) materials
(prices/availability/supply/quality/imports), (2) closure and blockade of borders, (3) project
team's experience in the construction type, (4) the experience and skill level of the
consultant and (5) clear and detailed drawings and specifications. Kendall's coefficient of
concordance was used as a measure of agreement between the two groups of
respondents (i.e., clients and consultants) who ranked various factors and it appears that
they are generally in agreement. Both clients and consultant groups should focus on the
main factors identified in this study to develop effective strategies for accurate cost
estimating, which would ultimately lead to successful projects.
