Mina Rashid Marina, Phases 2 and 3

New networks under a working estate.

DP World’s redevelopment of Mina Rashid turned Dubai’s historic port into a waterfront district with a marina. Working for the main contractor, Shafa Al Nahdah, AZEMCO installed the cabling and firefighting networks across Phases 2 and 3, including the 11 kV networks of Phase 3, while the estate around them stayed in use.

What made it hard.

1. 01

   An estate in daily use

   Trenching, cable pulling and pipe laying had to fit around traffic, operations and other contractors on an estate that never closed.

2. 02

   Two networks in the same corridors

   The 11 kV cables and the firefighting mains often shared routes, so they had to be planned together to keep the separation and access each needs.

3. 03

   A fixed date for Phase 3

   The Phase 3 11 kV networks had to be ready for energisation on the main contractor’s programme, with no room to slip.

What we did about each one.

1. Challenge 01An estate in daily use
   Our response

   Short sections, reinstated as we went

   We opened the routes in short sections, with traffic management and permits, and reinstated each one before moving on, so the estate kept working around us.

2. Challenge 02Two networks in the same corridors
   Our response

   One route plan for both networks

   Our engineers set out the cable and hydrant routes together, with crossings, separations and valve chambers fixed before any excavation.

3. Challenge 03A fixed date for Phase 3
   Our response

   Daily coordination with the main contractor

   We planned each week against Shafa Al Nahdah’s programme and coordinated daily with the other trades. The Phase 3 11 kV networks were completed on programme in February 2019.

From the first drawing to handover.

1. 01Set-outRoutes for the cables and the hydrant mains surveyed and set out together.
2. 02Trenching and ductsTrenches opened in short sections, ducts and pipes laid, and the ground reinstated.
3. 03Cables and jointing11 kV and LV cables pulled, jointed and terminated.
4. 04Firefighting networkHydrant mains, valves and hydrants installed and pressure tested.
5. 05Testing and handoverCables tested before energisation, and the networks handed over on programme.

The Phase 3 11 kV networks were completed on programme in February 2019, and the main contractor wrote to thank the team.
