Dear planning engineers and claim analyst,
Let me just state my case: We are a General Contractor building a 39-storey medium end Residential Building at our place in Manila, Philippines. The client and its architect decided to have a value engineering by changing the original design of a Dry wall (ficem board) partition into 4" CHB (650 psi non-load bearing) plastered finish to save cost. In view of the clients convenience they will surely save a lot but I had submitted a time extension claim of 4 months which has an extended overhead of more than what the savings will be due to this change in design. If you agree with me the revision of design would inflict additional time to our schedule since the two activities lies on the critical path.
Here is the dillema: The clients representative and technical personnel didnt agree due to their reasoning that CHB wall can start sooner than dry wall since it is the wet works part and it will not wait until the sealing off of the building.
May I hear your own insight on this case?
