Register for MEED’s 14-day trial access 

Dubai Municipality has issued a request for proposals (RFP) to construct a stormwater drainage system on Sheikh Mohammed Bin Zayed Road and Al-Yalayis Road.

The project is designed to improve drainage along two major transport routes, reducing the risk of flooding and maintaining traffic flow during heavy rainfall.

It covers civil; mechanical; electrical; instrumentation, control and automation; and pipeline works, including construction of stormwater drainage lines of various diameters.

The authority said the project will also include manholes, chambers, catch basins and vortex connections to existing networks. Non-disruptive pipeline installation methods are also specified.

Bidders must submit technical, commercial and qualification proposals via Dubai Municipality’s electronic supply portal by 25 August.

Evaluations will consider technical capabilities, company experience and the financial offer, the municipality said.

The RFP details microtunnelling works for pipes ranging from 200 milimetres to 4,000 milimetres in diameter. This includes excavation, shoring, access and reception pits; traffic management; site protection; and the testing of materials and completed works.

Contractors must also establish and maintain offices, equipment and vehicles for the supervising engineer’s staff throughout the project.

Meanwhile, the municipality has opened bidding for the supply, installation, testing and commissioning of a stormwater network at the Jebel Ali sewage treatment plant. Bidders are required to submit proposals by 3 September 2025.
