• To make something happen later than expected,or to be performed later than planned.

Delay Definition

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.

3

Types Of Delay :

4

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.

5

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.2. Errors & omissions in the plans and specifications.

3. Differing site conditions or concealed conditions.

4. Usually sever weathers.

5. Intervention by outside agencies.

6

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.

7

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.

8

Note:

Compensable depends primarily on the terms of the contract.

But in most cases:Does not receive any additional money but time extension.

9

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;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.3. Disputes.4. Lawsuits.5. Abandonement.

Conclusion

Delays are inevitable( unavoidable);

But can be minimized by: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.
