the building's tower crane (with the aid of temporary-support platforms cantilevered off the side of the structure), erected in what would become one of the Belvedere's lift shafts. Contracts All the buildings – save for the hotel – were built as "shell & core" contracts, with tenants leasing their spaces from Chelsea Harbour Ltd. through their letting agents. Once each building was wind and weather-tight, and connected to the external services, tenants commissioned their own contractors for the internal finishings. Bovis project-managed the construction of the hotel from piling-level to roadway-level, and the remainder of the structure above-ground was completed by a client who had concluded a long lease with Chelsea Harbour Ltd. The civil and structural engineers for the project were Clarke Nicholls and Marcel of Hammersmith, London W6. Marketing Harrods Estates were asked to manage the residential aspects such as the sale and letting of properties. The 310 apartments were marketed with prices starting at around £2 million per property. The 261,000 sq ft of land has 24-hour security patrols, and residents have 24-hour porterage.

The lock accessibility was indicated by a huge hollow sphere rising-&-dropping on a mast topping The "Belvedere", visible for a long way both upstream and down, and connected to a tide gauge by the lock gate giving into the Thames.
