INTRODUCTION Definition Types Factors & Causes Impacts Conclusion
• To make something happen later than expected,or to be performed later than planned.
• A situation where the contractor and the project owner jointly or severally contribute to the non-completion of the project within the agreed contract period.
Delay Definition
Types Of Delay :
1. Critical & non Critical Delay:
• Critical delays� : Prevent the contractor from finishing the work on the scheduled completion date
• � Non critical delays: affect the progress of the work.
2. Excusable Or Non Excusable Delay:
Excusable Delays:� Unpredicted
1. �General labor strikes,Fires,Floods , Owner-directed changes.
2. �Errors & omissions in the plans and specifications.
3. �Differing site conditions or concealed conditions.
4. �Usually sever weathers.
5. �Intervention by outside agencies.
2. Excusable Or Non Excusable Delay:Non excusable : �
1. �Late performance of subcontractors.2. �Untimely performance by suppliers.3. �Faulty workmanship by the contractor and subcontractors.4. �A project specific labor strike.
3. Compensable or Noncompensable Delay:
A compensable delay:� • Time extension • Additional compensation. • Only excusable delays can be compensable.
� A noncompensable delay: • Neither additional compensation nor a time extension.
Note: �Compensable depends primarily on the terms of the contract.
But in most cases:Does not receive any additional money but time extension.
4.Concurrent or Non Concurrent Delay:
• Two or more delays that occur or overlap within the same period,
• One an employer risk event, the other a contractor risk event
• The effects of which are felt at the same time.

Methodology Likert five-point scale ranging from 1 (Very Low) to 5 (Very High).
five point scale starting from (1 =Very Low), (2= Low). (3= High), (4= Medium) and (5 =Very High). The Relative Importance Indices (RII) is computed as follows;
Where,
W is the weighting given to each factor by the respondents starting from 1 to 5
A is the highest weight in the scale which is 5,
N is the total number of respondents (which is 47 people).
Impacts of Delay 1. Cost overrun.2. Overtime .3. Disputes.4. Lawsuits.5. Abandonement.
ConclusionDelays are inevitable( unavoidable);
But can be minimized by:● �Detailed Site Investigations.● �Careful monitoring and regular meetings.● �Effective site management.● Collaborative working and effective coordination.● �Careful scheduling.● �Full commitment to the project by all parties.
