Southend Pier Extension
Overview
- Client: Southend-On-Sea Council
- Project Value: £700,000
- Dates: July – Sept 2021
The purpose of the project was to provide structural support to the proposed toilet block and viewing gallery on Southend Pier. Due to the nature of the proposed toilet block that is intended to “sit” on the pier, the existing pier structure was considered insufficient to support the proposed load. The new toilet block sits on the same footprint as a previously demolished toilet block, the original structure was supported by timber cantilever beams which are deemed structurally insufficient; therefore a new steel structure was proposed.
The project was carried out on behalf of Southend-on-Sea Borough Council and is a part of the £2.5million capital investment into Southend-on-Sea’s pier head, following engagement with residents and visitors.
GPS MACS were awarded the works as Principle Contractor. The challenging site required detailed planning and precision execution, working alongside the Grade 2 listed Pier and 1.5km off the coast.
