THE GOVERNMENT should consider allowing independent experts to investigate the alleged corruption within the Department of Public Works and Highways (DPWH), an infrastructure think-tank said Thursday.

DPWH Secretary Mark A. Villar earlier this week formed a task force composed of department officials to probe anomalies inside the agency.

InfrawatchPH Convenor Terry L. Ridon, however, said an internal investigation would be regarded as merely for show after President Rodrigo R. Duterte lashed at the department last week for corrupt practices.

鈥淭he department鈥檚 anti-corruption task force requires independent views to ensure that its findings will be transparent and made with integrity,鈥 he said, 鈥淎nything less will be perceived by the public as a 鈥榢omite de abswelto鈥 if the task force will be composed of agency officials and personnel.鈥

Presidential Spokesperson Harry L. Roque said on Wednesday that it is not 鈥渋nconceivable鈥 that Mr. Duterte may create a separate task force for DPWH 鈥渋n the same way he formed one for PhilHealth.鈥

Mr. Ridon said 鈥渓egal bid rigging鈥 of government contracts is the main problem in government projects.

鈥淎 review of infrastructure projects with only single bidders would show that its project prices offer no substantial variation from its approved budget, which is the ceiling price for all projects. In one of the more controversial DPWH projects in Metro Manila, the final contract price of P389-Million only had a 2.04% variance from the approved project budget of P398-Million,鈥 he said.

This system, he said, allows private contractors and government employees to collude.

The Presidential Anti-Corruption Commission has previously listed DPWH as the most corrupt government agency. 鈥 Kyle Aristophere T. Atienza
