Method Statement for Temperature Control and Monitoring for Mass Concrete 5. Concrete Batch Plant Supplier The Plant Manager shall monitor the prevailing Ambient conditions, concrete mix temperature trends etc. The Site Engineer and the QC will monitor the concrete placement and will notify the Site Agent of any unacceptable materials or operations for action. The materials and Mix design must be approved and available at the site.

Assist in constructing and later disassembling reinforcement braces, concrete forms, scaffolds and temporary structures. The consultant will review the test results and will take the required action.

The HSE inspection shall take place before concrete works start to ensure that the work area is safe i. adequate access, adequate illumination if working on night shift, good concrete pump arrangements, checking the formwork and supports, scaffold inspections, if applicable.
