THE CONTRACTOR of the Skyway Stage 3 project, DM Consunji, Inc. (DMCI), said it is still investigating the cause of yesterday morning’s collapse of a rebar cage that blocked the Buendia part of Osmeña Highway in Makati City, causing heavy traffic congestion in the busy area. Five of the company’s workers sustained minor injuries while two private vehicles were damaged. DMCI, in a statement, said it has attended to the injured and the damages. “Our workers have received medical attention and we have opened the North and Southbound Buendia flyover to vehicular traffic,” the company said. The Northbound service road was closed until 5 p.m. due to the incident, while the South service road is expected to be reopened by 6 a.m. today. The P26.66-billion Skyway Stage 3 project is a six-lane elevated expressway that spans 14.82 kilometers from Buendia in Makati City to Balintawak in Quezon City. — Arra B. Francia with a report from
