1. Objective.
This Method of Statement establishes all procedures proposed by China
Harbor Engineering Company LTD to complete the Drainage 4U-Ditch Plan
for Colon Container Terminal Phase III - Stage 1 PK III-1G.
2. Scope.
The purpose of this document is to describe the work method shall be
used, to efficiently complete the Drainage 4U-Ditch Plan for Catch
Basin.
All construction activities will be completed in strict adherence to
Quality, Safety regulations and with respect to the friendly environment.
3. Reference Drawings on this Document.
3.1 Here in following drawing referenced in this document.
a. GC-01, GC02 Drainage System Layout
b. GC03, Details on existing Drainage System.
c. GC4, GC5, GC6, GC7, GC8, GC9, New Drainage System Details.
4. General Construction Arrangement.
The construction equipment is detailed in each of the separate drainage
scheme. The combination of cast-in-situ and prefabricating method is used
for the 4U ditch. The prefabricated section is completed in the precast yard
and then transported to the site by flat-bed trailer for hoisting, and the
construction of cast-in-situ section is carried out after the prefabricated
section is installed.
5. Construction Method of 4U-Ditch.
5.1 Construction Schedule
The cast-in-situ method is used for the construction of all 4U-ditches in this
project. The 4U-ditch is 631m long in total. It has been established a
progress of 20m length, on daily basis for a total of 35 days, 2 team will be
on site to comply with this proposal, scheduled to commence works on Oct.
21, 2013 to Nov. 25, 2013.
Dimensions on 4U ditch, refer to:

5.4 Excavation
5.4.1 The side boundary of the pipeline shall be determined and marked
according to the location on the drawing, and the gauge pile shall be
driven. According to the pipeline after setting out, the actual position
and length of the pipeline shall be checked, and the mini-excavator
shall be used and coordinated by manual excavation.
5.4.2 During excavation, the designed elevation of the bottom of ditch shall
be strictly controlled. 10m shall be reserved for bottom cleaning
manually by the workers in the case of mechanical excavation, and the
attached figure shall be added to illustrate the reserved part, so as to
avoid that the undisturbed soil at the bottom of ditch is disturbed by
over-excavation during mechanical operation.
5.4.3 To prevent from ponding in the ditch, the gutters are excavated on
both sides of the ditch, the collecting well shall be provided at intervals,
and the sewage pump shall be used to pump the water to the
temporary drainage system. The excavated ditch shall be leveled, and
tamped by workers.
5.4.4 The graded broken stone bedding (see letter CHEC-SBT-040) shall be
