Implementation Program (DRAFT) IMPLEMENTATION PROGRAM FOR PASIG-MARIKINA RIVER CHANNEL IMPROVEMENT PROJECT (PHASE III) OCTOBER 2011 Pasig-Marikina River Channel Improvement Project (Phase III) Particular Conditions On Preparation of Implementation Program This Implementation Program (I/P) for Reference was prepared to assist the DPWH in preparation of his I/P in accordance with the DPWH’s proposal for implementation of Phase III. For the improvement of Pasig River Channel, the DPWH intends to implement all the Potential Areas including the Priority-3 Group and to complete the Phase III in June 2016. In details, there are major differences between the results of JICA Preparatory Study and DPWH’s proposal, as follows: a) Scope of Works of Phase III JICA Preparatory Study DPWH’s Proposal Improvement of Pasig River Priority-1 and -2 Groups. All Potential Areas (Proority- 1, -2 and -3 Groups) Improvement of Lower Marikina River There is no difference. b) Implementation Schedule of Phase III JICA Preparatory Study DPWH’s Proposal Procurement of DPWH March 2012 to February 2013 March 2012 to August 2012 Consultant (12 months) (6 months) Procurement of Contractors March 2013 to April 2014 September 2012 to June 2013 (14 months) (10 months) Construction Time May 2014 to April 2017 July 2013 to June 2016 (36 months) (36 months) c) Project Cost of Phase III JICA Preparatory Study DPWH’s Proposal P7,361.5 million P8,008.69 million It is assumed that JICA loan in this Implementation Program be provided for the DPWH’s proposed Phase III including Priority-3 Group of Pasig River Improvement. 1-2 PHASE IV (Improvement of

III) iii CHAPTER 1 INTRODUCTION 1.1 Background and Necessity of the Project The Pasig-Marikina-San Juan River System, of which total catchment area is 635 km2, runs through the center of Metro Manila and flows out to the Manila Bay. Its main tributaries, the San Juan River and Napindan River, join the main stream at about 7.1 km and 17.1 km upstream from the Pasig River mouth, respectively. The three largest waterways contribute largely to the flooding in the metropolis brought about by the riverbank overflow of floodwaters. Metro Manila, which encompasses 16 cities and 1 municipality having a total projected population of over 11 million in 2010, is the economic, political and cultural center of the Philippines. A master plan of flood control for the Pasig-Marikina River including the drainage in Metro Manila was prepared in 1952. In line with the flood control plan, the improvement works of the Pasig River, consisting mainly of river
