Construction operations definition
However, the term is defined more precisely by the Housing Grants, Construction and Regeneration Act 1996 (HGCRA, also known as the Construction Act). Whether works set out in a contract are considered to be construction operations for the purposes of the Act affect the parties' obligations and rights.
The Act suggests that 'construction operations' include a very wide range of construction and engineering operations. However, activities such as mining, nuclear and power generation are expressly excluded, as are contracts with residential occupiers. Section 105 of the Act sets out the precise definition.

- Telecommunication apparatus.
- Aircraft runways.
- Docks and harbours.
- Inland waterways.
- Pipe-lines, reservoirs, water-mains, wells, sewers.

- Power supply.
- Water supply or fire protection.
- Security or communications systems.'
- Site clearance.
- Tunnelling and boring.
- Laying of foundations.
- Erection, maintenance or dismantling of scaffolding.
- Site restoration.
- Provision of roadways and other access works.'
 Part 2
'Assembly, installation or demolition of plant or machinery, or erection or demolition of steelwork for the purposes of supporting or providing access to plant or machinery, on a site where the primary activity is:
- Nuclear processing, power generation, or water or effluent treatment.
- The production, transmission, processing or bulk storage (other than warehousing) of chemicals, pharmaceuticals, oil, gas, steel or food and drink.'
