Dunya Tower - Ground Floor_ LV Room

Scope Of Work:

1. Supply

• Provide insulating rubber mats rated for safe use in LV switchgear rooms, suitable for personnel standing in front of live or potentially live equipment.
• Mat characteristics:
• Minimum thickness: 3 mm (or as specified).
• Surface finish: ribbed or anti-slip.
• Width: minimum 1 m, and extend at least 1 m beyond the total width of each LV panel section.
• Mats shall carry permanent markings including: class/rating, manufacturer name, batch/lot number, voltage rating.
• Provide product datasheet and material compliance certificate for review/approval prior to installation.
• Ensure materials comply with DEWA’s requirement for equipment and materials: all equipment and materials shall be selected in accordance with “Standards for equipment and materials” in DEWA’s Regulations for Electrical Installations.

2. Preparation

• Inspect the LV room floor area: verify floor is dry, level, structurally sound, free of oil/grease, debris, sharp edges or protrusions.
• Confirm that the layout of mats is coordinated with the client/consultant and aligns with the switchgear arrangement.
• Provide or review layout drawing showing the mat arrangement in front of each panel for client/consultant approval.
• Carry-out any floor repair, cleaning or priming necessary so that mat adhesion (if required) is effective.

3. Installation

• Roll out and place the insulating mats in front of the LV switchgear/MCC panels ensuring full coverage of the designated zone.
• Ensure mats lie flat, with no folds, wrinkles, bulges or gaps. Overlap joints if required using manufacturer-approved method.
• Fix mats to prevent slipping – using non-conductive adhesive or mechanical edge strips as specified by the mat manufacturer.
• Ensure all markings remain visible after installation.
• Ensure installation is done without damage (cuts, punctures) to the mats; rectify any defects prior to testing.
• Confirm that workmanship is “neat, orderly and in a workmanlike manner”, consistent with DEWA’s workmanship requirement.

4. Inspection & Testing

• Conduct visual inspection: verify alignment, coverage, condition, and visible markings.
• Where required by project specification, perform dielectric (insulation) test of the mats or verify that manufacturer’s test certificates apply.
• Prepare and submit an installation completion report including: photos of installed mats, compliance certificates.
• Coordinate with site FM team for final inspection and approval.
