Crossrail Ltd (CRL) required its tier 1 contractors to record water consumption on a periodic basis. A summary dataset has been made available on water consumption across the Crossrail Central Section Contracts. This data could be useful to future projects as a basic comparison to construction projects with similarities listed below and enable knowledge to be built up across the industry to support the setting of benchmarks in this area.
- Operations/ Construction Phase
- Contract Value at Award
- Contract duration
- Construction area
It is interesting to note that the contract value does not have a bearing on the amount of water used.
Several Best Practice examples in terms of water consumption were observed across Crossrail Tier 1 Contracts and the details of these are contained in the Learning Legacy Paper Best practice in Water Use on Crossrail.
