President Duterte has been grossly misinformed, hence he barked up the wrong tree. He should have asked his own Department of Public Works and Highways, being the procuring and implementing agency of the project.
It was the DPWH that prepared the Program Of Works, the Terms of Reference and all bid documents, conducted the bidding, awarded, prepared the contract, signed the contract, and issued the notice to proceed, including the cost of the building. The Senate representative was only an observer during the bidding process.
In fact, after the notice of award was issued, I took time to warn the contractor in the presence of some DPWH officials against giving SOP’s to anyone and in whatever form, particularly on the construction of the new Senate building.
