METHOD STATEMENT FOR APPLICATION OF ANTI- TERMITE TREATMENT AT SOIL

SCOPE
The intention of this method statement is to describe the procedure and responsibilities of personnel involved in the application of anti-termite treatment on the sub-base of the structure.

2.0 RESPONSIBILITY

The Project Manager is overall responsible for all aspects of the work/project.

The Project Site Engineers are responsible for the proper execution, arrangement, coordination, and supervision of quality, safety, and delivery of work.

The Anti-termite subcontractor is responsible for ensuring that the delivered chemicals are as per the approved materials. They are also responsible for the proper mixing and application of the chemicals on site.

The QA/QC Manager & Engineers shall ensure that the execution team follows this method statement and implements the site inspection procedures. The QA/QC Engineers shall monitor, check, control, and document the quality of work during the entire duration of the treatment.

The Safety Engineer or Safety Officer will ensure the implementation of safety measures at the worksite.

3.0 MATERIALS & EQUIPMENT

Approved Anti-termite Materials
Clean Water and Water Pumps
Polyethylene Sheets and Water Drums
Mixing Equipment (if necessary)

4.0 EXECUTION

The soil substrate should be approved by engineers and the invert elevation should match the shop drawings.

All materials/chemicals should be inspected and approved by engineers.

The Anti-termite applicator should be approved or certified by local authorities.

5.0 PREPARATION

The soil surface should be properly compacted (if necessary), and all loose materials should be removed.

The work should be coordinated with the Safety Department before proceeding with the activity.

Mixing of materials should be done as per the applicator/manufacturer’s recommendation.

6.0 APPLICATION

Internal Area

Footings – The excavated area of footings will be treated by spraying termiticidal solution on the exposed soil surface prior to concreting.

Foundation Walls – The adjacent soil surface along the perimeter of foundation walls and both sides of interior partition walls will be treated by spraying termiticidal solution as necessary.

Slab – The soil surface adjacent to building slabs and attached slabs will be treated by spraying termiticidal solution prior to concreting.

Penetrations and Joints – Expansion joints, control joints, and areas where slabs will be penetrated (e.g., around plumbing pipes, electrical/telephone conduits) will be treated by spraying termiticidal solution on the soil surface as necessary.

Ground Floor – The ground floor level will be treated after compaction by spraying termiticidal solution on the soil surface prior to the floor slab concrete works.

External Area

The soil around the building at the foundation/perimeter level will be treated as per the manufacturer's recommendation before fixing the interlock tiles or concrete works.

Special Note: Any structural changes in treated areas disturbed by construction activities, such as breaking concrete slabs, digging trenches or pits, re-filling, or leveling, should be reported to the applicator contractor for re-treatment to restore the chemical barrier.

If the treated area is exposed to ultraviolet rays or heat for more than 24 hours in summer and 48 hours in winter, and is not protected by polyethylene sheets due to delays in concreting works, it is advised to re-treat before proceeding with concreting.

7.0 FIELD QUALITY CONTROL

Monitor the delivery of materials, temperature, mixing at site, and application.
The application of anti-termite treatment should be inspected and approved by engineers.

8.0 SAFETY PRECAUTIONS

The prime importance shall be given to the safety of personnel and the protection of utility services. Personnel involved should be thoroughly aware of the company’s safety regulations.

Any machinery and equipment must be operated only by well-trained and experienced personnel.

Protective clothing and equipment will be necessary. Ensure that any special protective clothing or equipment required (such as helmets, eye protection, ear defenders, visibility vests, etc.) is ordered and available for use on-site. Subcontractors should also be made aware of any site-specific requirements.

Instruct staff on the correct application of hazardous chemicals that could cause injuries to the hands.

A risk assessment letter should be issued by the Safety In-charge before the start of the activity and should be posted at the working area during the activity.
