9. Form preparation
To ensure the quality and to lower prices of package, we will
use steel form, scaffolding, to prevent glue of form we
use SIKA SEPAROL.
II- MATERIAL PREPARATION, EXECUTION EQUIPMENT:
Through studying the designing and investigate current
market, We make a plan using materials as follow:
a. Models and sorts
Steel will be used in package is steel of Vietnam steel
corporation, ensure that is not rusty, greasy or dirty,
Contractor will carry out testing sample with steel package
which transported to site and fabricated standard must
according to TCVN 1651-85 and BS 4449, BS 4461. Must has
quality certificates, Trade-mark & supply schedule which is
suitable with execution schedule, Re-bar will be fabricated at
workshop by special machine
Stone, gravel, sand:
Stone, gravel, sand supply to C3 package are from exploited
enterprise located nearly site region, when they coming the
site it will be gathered on paltered floor or iron sheet
pavement, that is next to mixing concrete machine, ensuring
cleaning, size of seed in accordance with TCVN1770-86
required or other relevant standard.
Using Hoang Thach or Chinfon-HP cement, cement at site

With large component that need a large quantity of
concrete will be supplied Ready-mixed concrete of near
mixing plan and transported to site by mixer truck as NISAN,
KAMAZ, PUSO HINO…
Beside that with each site group, Contractor will arrange at
least 1 mixer (450l) to provide and supplying for small
Each 40 – 50m3 volume of concrete, it will be taken one set
of sample depending on structure . One time is 6 samples by

bank or water.
All execution equipment have a registration, enough
capacity, safety and clean up to environment. (having a look
at equipments sheet attached)
III- INVESTIGATION WORK AND PLACING OF CANAL
1- Plan investigation
In same time with site preparation, equipment, material…
mobilization. We carry out examine, investigate all surface
of plan to make a reasonable execution method.
Additional, Contractor carry out investigate electric, water,
telecommunication cable underground and traffic road,
house…on the plan to make a method to remove,
dismantle or select a suitable execution method, ensure to
