Abstract
The complexity of the construction industry due to different stakeholders’ involvement makes it
differ from other industry. This complexity gives rise mostly to unwanted situation like Delay and
time Extension with their attached effects. The aim of every construction project is to meet the
objectives of time, cost and quality. If the project is not completed on its time, and/or on its
budget cost and/or on specified quality unsatisfactorily, claim or dispute may raise between
stakeholders.Delay claims are extremely complex and difficult to resolve, for this reason projects
requires an effective and reliable method to minimize the cause and effect of construction
delay.That is why this research is focused on assessment of delay and time extension analysis
techniques and trend with selected consulting firms in Addis Ababa.
To achieve the study objectives, a critical review of relevant literature was done coupled with
questionnaire. Case studies also carried out to show the gap between delay and time extension
analysis techniques recommended in literatures and trends with selected consulting firms. The
research surveyedSix (6) samples Grade one consulting firms around Addis Ababa to assess the
techniques that how time extension delay analysis are prepared and evaluatedcompared with
literature and as per the standards stipulated in contract provisions.
The findings of this research indicate that, the consultants surveyed and the contractors worked
with themhavelack of experience in preparing and evaluating time extension delay analysis in
acceptable, procedural and scientific ways as per the standards stipulated in contract provisions.
Some concepts which are familiar in developed countries, like Time at large and No damage for
delay provision are not familiar in Ethiopian construction industry. Concurrent delays are not also
exercised in most of the consulting firms.
According to the research (34.78%) of the clients agree projects are completed with 200-300%
time extension of the original contract time. Thus, Project delays are the major cause of claims of
time extension and associated cost overrun.
