- Dates: November 21 – May 22
The Port of London Authority are planning to open the 200m long Plaistow and Royal Primrose wharves to commercial river traffic and business use. A condition survey was carried out to evaluate the condition of the wharves and give recommendations for repair prior to use. Keltbray were appointed as the Principle Contractor for the works with GPS Marine and Civil Services (GPS MACS) subcontracted for the works.

The PLA’s total investment in site acquisition and improvements readying them for operations is some £20 million.
