Quezon City, Philippines

With an exploding metropolitan population of more than 10 million, East Metro Manila water concessionaire Manila Water Services, Inc. (MWSI) is improving its service to cope with the growing demand. According to their annual report for 2010, “Water service is a critical component of national development, developing our reach across the country will significantly contribute to the improvement of the quality of lives of our fellow Filipinos, spur business activity, and generate the multiplier effect from our investments in these areas.”

Part of that improvement is the construction of huge water and sewage treatment facilities.

A long-time EFCO customer was awarded the contract to build a water treatment facility in Tandang Sora, Quezon City. EFCO and the contractor worked together to devise a solution to fast-track the structure with minimal concrete re-work.

EFCO's PRO 4 shoring system is designed to be either handset or engineered to move in large modular towers. The shore towers were constructed on the ground in a horizontal position and then tilted up to be a vertical tower at 39'-0" (12 m) tall.

The EFCO SUPER STUD® and E-BEAM® system was used to form the project’s straight and wing wall configurations. The contractor built gangs measuring 4.5 m (15′-0″) in height and jumped the system three times to complete the structure at 12 m (39′-0″). EFCO E-BEAMS used in conjunction with SUPER STUDS and contactor supplied plywood produced a lightweight wall forming system. Weighing approximately 60 kg./m2 (12 lb/ft2) including pipe braces and scaffold brackets, the system produces superior concrete finish and consumes less crane time.

The EFCO PRO 4 shoring and decking system was used for slab construction. The system is different from other shoring systems. It is designed to be used both in handset and in gang forming situations. The contractor built 12 m (39′-0″) high gang towers and with the use of dollies, the crew easily cycled the shoring by pushing the tower from finished pour to the next pour.

Duly satisfied with the work shown by the contractor, MWSI has awarded to them additional structures: a 100 million liters (26.5 million gallons) per day sewage treatment plant and a water treatment plant at Bahay Toro in Quezon City. The future looks bright for now, since the annual report for 2010 stated, “We are committed to investing in infrastructure and expansion to bring reliable, safe and affordable water to Filipinos across the country. We will continue our promise to protect the environment for future generations.”
