:
- The Customer to ensure congenial working environment free from any encumbrance, disturbance, extortion and or toll collection at the Project Site. For any adverse consequence, any loss, damage to the property, material and or physical harassment inflicted to the workers/personnel’s all liabilities thereto will be on Customer.
■ Erection materials, tools and equipments should be allowed to be taken out for any modification or engineering work outside the site without interruption at the Contractor’s convenience.
- 1) Handling and Storage : To preserve the sheeting material surface, handling should only be carried out using clean, dry gloves. Do not slide sheets over rough surfaces or on each other. Packs of Hi-Ten Steel Cladding sheets in all finishes must be kept dry in transit and stored on clean ground under cover to prevent water and / or condensation being trapped between adjacent surfaces. If packs become wet, sheets should be separated, wipe with a clean cloth without delay and place so that air circulation completes the drying process. These procedures are recommended to avoid possible deterioration of the coating which could lead to a reduced life expectancy or poor appearance.
- 2) Additional Care for Decking Arrangement: In the event of concreting on Decking Materials including Decking Beam, adequate number of Props must be used under the Beam & Slab during concreting. Till the settlement and perfect curing of the concrete, placement of additional load on the said floor to be avoided. After propping arrangement the floor must be placed before MSBS authorized representative for checking, and after their acceptance only the concreting can be started.
