Two hall extensions, the same technical content – one on an empty plot, the other in the yard of a factory running three shifts. The insurance picture for the two projects is worlds apart: on a greenfield site, the works are the main risk; in an operating plant, the client's property and business continuity are at least as much at stake. This article compares the two situations – with pointers for the decision.
- Greenfield: the risk is concentrated on the works under construction and the site – the cover picture is simpler.
- Operating plant: existing property, continuity of production and strict plant rules add the extra layer.
- In an operating plant, work scheduling (shutdown windows, permits) meets the cover's terms head-on.
- The client's sensitivity to business interruption can be the project's biggest hidden risk.
Greenfield: a clean slate
On an empty plot, the risk picture is easy to survey: contract works, temporary works, machinery, natural-catastrophe losses, and the world outside the fence, covered by the liability section. The question of existing property doesn't even arise; logistics (storage, transport) and weather exposure are the main planning points. The industrial-hall article largely describes this situation.
Operating plant: layered risk
In a production environment, three extra layers come into play. Existing property: the plant's buildings, production lines and stock sit right next to the work site – the extension for this is a basic requirement here. Business continuity: a construction defect doesn't just cause damage – it can halt production, so the sizing of the contract and the liability limits should follow the client's sensitivity to business interruption. And the rulebook: the plant's health, safety, fire and process rules (permitted work, sealed-off zones, escort staff) also bind the contractor's working routine – under the applicable rules in force.
Work scheduling as risk management
In an operating plant, a good schedule has the value of cover in itself: critical work arranged around shutdown windows, the plant's permit regime for fire-hazardous phases, a pre-agreed choreography for utility disconnections. Documenting these is the contractor's best protection at claim time – and, from the plant's side, the list of requirements should be an annex to the contract: the clause article.
Consequences for the decision
When requesting a quote, an accurate description of the situation comes first: a greenfield or an operating environment, how close to production, with what scope for shutdowns? Cover for a project in an operating plant is typically more complex – and this is exactly where quotes start to differ when tendering: the comparison table.
