INTRODUCTION OF PROJECT

1.1INTRODUCTION
Hanoi Pilot Light Metro Line, section Nhon - Hanoi Railway Station is a major project fo r Hanoi City.
According to the Hanoi Transportation Master Plan till 2020, total length of HPLML (Line 3) shall reach
21,5km from Nhon to Hoang Mai.The first phase of this line, and part of this Contract is from Nhon to
Hanoi Railway Station, with about 8.5 km elevated section and 4.0 km underground section. This line
includes 12 stations (with 8 elevated and 4 underground stations). The Depot is located at Nhon with area
of 150,550m2.
The CP01 Contract’s work scope is Viaduct Line at Elevated Section, including the construction of
viaduct structures which link along the National Road No32, Ho Tung Mau, Xuan Thuy, Cau Giay and
interfaces with underground section at the beginning of Kim Ma Street. The contract shall be completed
and within 30 months from the date of the Commencement Date.
Both metro and structure alignment follow the current and/or planned median road. Viaduct structures are
divided into standard viaducts which cover most of the elevated section and special viaducts where long or
special spans are required to pass over major constraints (2nd Ring Road, 3rd Ring Road, Nhue River).
Other non-typical structure consists in Cross Over (metro line requires switches), ramps to depot and
underground sections and Y-bridge (branches off to depot). The overview of the project is shown in photo
below:

SCOPE OF WORK

2.1GENERAL
Structure excavation work of Project will be carried out within the narrow area and with the great depth of
excavated hole. Therefore, Shored excavation method will be applied to ensure stability of excavation
hole for structure construction.
Shored Excavation shall be undertaken in accordance with clause “3.4 - Shored excavation, Part II,
Chapter II-2” of Technical Requirement. This method is generally applied to Shored excavation to the
design bottom elevation for all pile caps using shoring system.

This method also includes disposal of unsuitable excavated material, dewatering works and related works
to be free from the accumulation of ground water and artificial runoff water inside excavated area. Shored
Excavation shall be done in accordance with the perimeters and slope as indicated on the approved
working drawing.
2.2SCOPE
The Contractor shall set up and submit method of shored excavation. The Contractor can adjust method

for shored excavation in accordance with the actual condition on the site or at the direction of Consultant
Engineer. All adjustments will be reviewed and approved by the Consultant Engineer, Employer.

3.2REFERENCE TO BORE HOLE
Based on alignment geological borehole, we have reference table of geological boreholes in accordance
with pier position. Reference table is established for piers of Typical Bridge and Special Bridge.
With dimension, depth and geology of borehole at position of piers, Contractor calculated and proposed
all piers in alignment have to use sheet piles cofferdam during excavation process.
Also, at position of pier caps with dimension (10.9x7.4x3.5m và 5.6x4.8x3.0m), Contractor use bracing
system inside steel piles cofferdam.
Dimension, sheet pile cofferdam lay out, scope of application spreadsheet for all kinds of pier cap on
Typical Bridge is shown in the attached drawing in section 10.1.1.
Dimension, sheet pile cofferdam lay out, scope of application spreadsheet for all kinds of pier cap on
Special Bridge is shown in drawing DLM-IMP-GPV-WVO-JOO-10003-B and DLM-IMP-GNS-WVOJOO-10018-B (attached in section 10.1.2).
Spreadsheet for pier cap in the most unfavourable when constructing pier cap with cofferdam without
wales & struts inside, will be submitted separately.
Spreadsheet for pier cap in the most unfavourable when constructing pier cap with cofferdam and wales &
struts inside, will be submitted separately.
