3. WORK PROCEDURE:

The work procedure is described as follows:

4.1 PREPARATION WORK:

Before carrying out any work, check the followings as listed below:

- Checks all approved shop drawings and confirm latest drawings are used.

- Confirm all materials procured against material approval list.

- Ensure that approved installation details methods are fully comprehended by the

workers.

- Clear area under installation location and install warning tape for forbidding non-

authorized person to enter.

- Support for fan shall be prepared prior to installation work.

- Check dimension of fan’s support to ensure enough space for installation fan.

- The coordinates and level shall be followed approved shop drawing and confirmed with

Engineer prior to the commencement of construction works.

- Roof fan , Natural ventilator shall be approved and accepted for using by Engineer.

4.2 SURVEY FAN LOCATION:

After determining the coordinates and elevation level, location and level of Fan shall be

determined following approved shop drawing with Engineer’s representative. The support of fan

shall be fabricated basing on approved shop drawing in accordance with instruction by the

Engineer (if any).

4.3 INSTALLATION WORK:

4.3.1. Support Installation:

- Support shall be fabricated to follow approved drawing of Engineer and installed on the

steel structure of building.

- Support shall be painted with approved color prior to installation work.

- The survey work shall be done to confirm the location of support and to be checked by

Engineer.

- Installation work shall be carried out carefully because of high level. Workers shall

observe safety patrol for working at high level.

- Supports shall be fixed to steel structure by bolt and nut with washers after that checking

its stable by visual and shaking by hand.



4.3.2 Fan installation:

Fan shall be installed on the steel support or concrete base. The dimension of both kind have to

follow the manufacture specification.

Fan shall be fixed to support by screws or bolts with quantity and size basing on approved shop

drawing and instruction of Engineer.

The rubber isolator with 10mm thickness shall also be installed between fan’s base and support.



The balance and level of fan shall be check carefully prior to fixing work.

Screw or bolt for fixed fan to support do not over-tighten to prevent distortion of fan base (in

case fan case made by GPR, fiberglass) and rubber isolator.

Water proof work shall be carried out carefully to ensure non-leakage when it rain. Every gap,

joint shall be sealed by suitable caulking material which is approved by Engineer.

4.3.3 Testing work:

Air flow rate of fan (except Natural ventilator) shall be tested basing on the specification.

Electrical power (voltage, ampere) shall be also check to ensure the operation of fan with

correctly condition.

4.3.4 Completion work:

At the end of Mechanical work, all equipment and redundant material shall be removed and

transported to another place. Clean up the working place for next work team to start.

Touch-up paint to damage position on support before finishing work.

4.3.5 Electrical work:

Electrical work(power supply) shall be executed to follow the approved drawing by skill

electrical worker after Mechanical work finished.

certificate shall be submitted.

The Contractor should be submitted to the Engineer the related documents for approval

before delivery to site or start the construction.

The inspection report or specification of Fan shall be received before arrival of Fan on site.

Upon arrival on site, Fan shall be inspected as to dimensions, quantity, and physical

condition and reported to the Engineer.

4.6 SITE SUPERVISION AND PROCESS CONTROL:

Approved for materials shall be carried out prior to delivery to the project site. Constructions

shall be followed approved shop drawing by Engineer.

The Ventilation Fan, support, & accessories shall be checked and inspected for defects to

ensure that all material is good quality prior to install.

The work shall be supervised by qualified and experienced staff and executed by highly

skilled , experienced operators and workers.

5. SAFETY PROCESS:
