Piling operation shall continue until it completes the works on a given schedule.  Temporary Bridge and Platform Construction Sequence The construction shall commence from a given sequence. 1. Construction 3-800mm.dia. Steel Pipe Piles anchorage at North Bank Muelle de Industria Street, Binondo, Manila; 2. Setting Out Survey of Temporary Bridge and Drilling Platform; 3. Driving and Installation of Steel Pipe Pile Columns (800mm.dia.); 4. Installation of Connecting Plate (10x300x300)mm; 5. Installation and Assembly of Cross Beams (2HM488x300) mm.; 6. Installation and Assembly of Longitudinal Beams (I50b@400)mm & (I26@400)mm.; 7. Installation and Assembly of Cross and Longitudinal C25a@260mm. Deck slab; 8. Installation and Assembly of Guard Rail and Posts

 Construction of Cofferdam and Embankment along Muelle dela Industria Street. Piers B6-B13 through Abutment B14 to Sta. MK0+565. The Reclamation area along Muelle dela Industria Street using Cofferdam and Embankment will be necessary for the construction of the Pasig River Bank in preparation of the construction of Substructure and Superstructure of the North Approach Bridge. The Reclamation area shall be confirmed on final Detailed Engineering Design (DED) to be issued for construction by the Consultant and Department of Public Works and Highways, (DPWH).

Temporary Bridge 3-800mm.diameter Steel Pipe Piles Anchorage (North Bank) Method Statement starts the Temporary Bridge anchorage, a 3800mm.dia., Steel Pipe Piles at North Bank; Muelle de Industria described the construction of anchorage towards the construction of Temporary Bridge to the construction of Drilling Platform for Pier 5, Main Bridge including Pier 6 and Pier PB6 at Pasig River North Bank. Prior to the execution of the works, a Work Inspection Request (WIR) shall be submitted for Consultant Engineer’s approval and noted by the DPWH-UPMO Engineer. Once it is approved, piling works shall commence and will be ready for the installation and assembly of beam supports for the first span of the Temporary Bridge.

III.

Construction of Steel Pipe Pile Columns

 Pile Driving Specification Requirements Hereunder are the following:  Pipe Driving is the process of forcing the Steel Pipe Pile into the riverbed ground without excavation.  The Steel Pipe Pile should be driven vertically.  However, a tolerance of eccentricity of 2% of the Steel Pipe Pile length is permissible.  The eccentricity is measured by means of plumb bob.  The equipment required for Steel Pipe Pile driving are as follows: Pile Frame Pile Vibratory Hammer Leads Winch Miscellaneous

Figure 17.0- Pile Driving  The Method of Piling Works. 1. Delivery of Steel Pipe Piles by Trailer Truck from the Fabrication Plant and lift by a Crane for the commencement of Piling Works. 2. Mobilization of the Crane with Pile Driving Machine /Vibratory Hammer. 3. Lifting the Steel Pipe Pile lower segment by the Crane then mount with the Pile Driving Machine/Vibratory Hammer. 4. Driving the lower segment Steel Pipe Pile. 5. Lifting the Upper segment Steel Pipe Pile and splicing. 6. Driving the upper segment Steel Pipe Pile (Middle Top). 7. Confirm the bearing capacity by evaluating penetration during driving.

IV. Temporary Bridge and Platform Construction InGeneral  Setting out Survey of Temporary Bridge and Platform Prior to the commencement of the survey works, a Work Inspection Request (WIR) shall be submitted to Consultant’s Engineer approval and noted by the DPWH-UPMO Engineer. The location of the Temporary Bridge and Drilling Platform alignment shall be set out and peg by a licensed Surveyor based on approved setting out drawing from Consultant and control points at site. The surveying details of each location to be recorded, incorporating reduced level and coordinates. Each individually 19 | P a g e

surveyed Steel Pipe Pile position shall be protected from disturbance prior to commencement of the Piling works. Two (2) reference points are to be installed for reference checking and monitoring continuously during the execution of the Piling works.  Installation of Steel Pipe Pile Piers-800mm.dia. X 10mm.

The specification of Steel Pipe Pile materials is 800mmdia.x 10mm.thk.and length of 32.672meters for one (1) unit Pile as indicated in the drawing or at Top Elevation (+)3.082meters and Bottom Elevation (-) 29.59meters and duly approved by the DPWH and Consultant’s Engineers prior to be allowed for its use. Work Inspection Request (WIR) will be submitted to Consultant’s Engineer approval and noted by the DPWH UPMO Engineer prior to start the construction works. The Piling works of Steel Pipe Pile Columns for the Temporary Bridge and Drilling Platform can be done with Crawler Crane with attached Pile Driving Machine/Vibratory Hammer. Delivery of Steel Pipe Pile Materials is hauled by Trailer Truck from the Fabrication Plant and unloaded by a Mobile Crane for continuous piling operations. The Piling work sequence to adopt could be started from the North Bank at Muelle de Industria towards Pier P5 for the number of spans of the Temporary Bridge consisting of Steel Pipe Pile Columns, Cross and Longitudinal Beams, C25 Channel Deck slab and continuously done at Pier P5 Drilling platform. Following the completed Steel Pipe Pile Columns is the installation and assembly of the 10x300x300mm Connecting Plates; 2-HM488x300mm Cross Beams preparatory for the installation of Longitudinal Beam I 50b @ 400mm (I 36a @ 400mm); C 25a @ 260mm Deck slab; and installation and assembly of Fence (Guardrail and 4.80mm.x150 Posts) both sides.
