Agno Flood Control Project Phase I

DETAILED NARRATIVE DESCRIPTION OF PROJECT:

The project consists of the urgent rehabilitation works in the lower Agno and upper Sinocalan Rivers, which have been identified and prioritized based on the feasibility study for the Agno and Allied Rivers conducted in 1991. The civil works include the following components:

New Channeling and Channel: Bugallon; L = 1,650 m, Urbiztondo; L = 2,560 m; Improvement by Dredging and Ambayet; L = 850 m; also dredging along the lower Agno River stretch, 54 km (volume = 8.8 million cu.m.3)
Bugallon Bridge: Length of 392.5 m (11 spans, 7.3 m roadway)
Dike Heightening: Left dike of lower Agno near Aguilar 1-2 m height, Length = 3km, Volume = 93,000 m2.
Revetment: Gabion mattress type; 11,500 m for lower Agno River, 1,800 m for upper Sinocalan River
Rubble masonry type: 900 m for lower Agno River, 1,000 m for upper Sinocalan River, Total revetment length = 14,200 m

DETAILED DESCRIPTION OF ACTUAL SERVICES PROVIDED:

The Consultant’s scope of work involved the following tasks subdivided into three (3) phases:

Phase I –	Pre-Construction Stage – review of detailed engineering design of all components which were undertaken earlier, and detailed engineering design of added components in all of which PKII was involved and assistance during tendering;
Phase II –	Construction Stage – construction supervision and management including environmental study and monitoring; and
Phase III –	Consultant’s Close-Out Activities – preparation of completion report, maintenance manual, as-built plans and engineering study report.

Agno Flood Control Project Phase II

DETAILED NARRATIVE DESCRIPTION OF PROJECT:

As the second phase of the Agno River Flood Control Project, it involves the improvement of river stretch from Wawa Bridge to the entrance of the existing floodway with the following features:

1st stretch

Excavation of low water channel, construction of 11.9 km new dikes (0.7 km counterweight and 1.4 km revetment);

2nd stretch

Construction of 4.4 km guide channel; approach channel excavation (0.79 mil. cu. m); 11.7 km closure dike; 3.3 km revetment; 0.9 km spur dike, diversion structures and riverbed protection works;
