use SIKA SEPAROL.

II- MATERIAL PREPARATION, EXECUTION EQUIPMENT:

1/ Material

Through studying the designing and investigate current

market, We make a plan using materials as follow:

a. Models and sorts

Re-bar

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:



32



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.

Cement

Using Hoang Thach or Chinfon-HP cement, cement at site

SM 50Y, SM 53. Standard.

- Concrete pile is in accordance with BS591.

b. Organization

to

exploit,

transportation

and

maintain

In site management board, We establish a material,

equipment rooms, this one take charge to organize to

exploit, transport, store or hiding fabrication to meet project

schedule.

Material imported to the site will be stored carefully with

Contractor sign contact with supplier to guarantee that

materials supplied to site by mean of supplier.

2. Mobilization equipments

Execution equipment are included: Crane, driver, excavator,

Depend on kind of machine, which will be decided stand on

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

LINE

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.



34



Additional, Contractor carry out investigate electric, water,

telecommunication cable underground and traffic road,

house…on the plan to make a method to remove,

underground cable system, telecommunication company

to be early determine underground systems in site zone,
