At site, the contractor’s construction manager manages the work execution as well as the resources, and the workforce. He operates to achieve the contractor’s objectives, which include optimizing profit, maintaining a cooperative and harmonious relationship with the project manager and others engaged in the construction activity at site.
The completion of the construction phase of the project includes certain follow-up actions necessary to ensure that the facility constructed functions satisfactorily. These are as follows.

a)    The post-completion maintenance is usually entrusted to an agency familiar with the construction. In most cases, the contractor responsible for construction is given this responsibility one year after completion; and this aspect is included in the scope of work of the contractor.

b)    A proper record of the operating instructions and as-built drawings is maintained.

c)    The staff and workers necessary for operating  and maintaining the facility are trained prior to its taking over.

d)   The site is cleared of the left-outs of the construction and unwanted materials.

e)    The client fully safegurds his interests prior to rendering the completion certificate to the contractor, and also before making the final payments.

After completion by the contractor, it is the project team of the client that hands over the project to him. The team also prepares a project completion report which includes the scope and schedule of work, the important events, the contract executed, the addresses of the suppliers of materials and equipment, the equipment maintenance manual, the as-built drawings, the costs involved, the problems encountered during execution, the lessons learned and the minor defects noticed at the time of handing over.
