- Ground improvement and/or compaction.
- Excavation of known below-ground obstructions.
- Survey work.

- Provision of statutory utilities to the site.
Enabling works might be preceded by 'mobilisation' activities, carried out after the client has selected the contractor, but before works commence on site. These are preparatory activities, such as; preparing method statements, arranging road closures, placing necessary sub-contracts, and so on. See Mobilisation for more information.
'...works executed ahead of the main building contract. Enabling works are employer and/or project team specified works, which might include a mixture of facilitating works and new building works (e.g. site preparatory works such as major demolition, removal of contaminated materials, reptile mitigation measures, and soil stabilisation; together with new sewers, new access road, new drainage, new retaining walls, and minor new building works).'
‘…all components measured and incorporated in group element 0 (i.e. Facilitating works). Includes specialist works which, normally, need to be completed before any building works can commence (e.g. major demolition works, soil stabilisation works and or temporary diversion of mains drainage).’
- On site sooner.
- Can saves time and money.
- Could have a specialist contractor for carrying out that particular type of works eg. demolition.
- The cost and time to make up two separate contracts
- Process complexity involved in making up two separate contracts
- If there are two different contractors; liability and hand-over issues.
