Focus before mobilisation: confirm current information, package boundaries, access, area release, trade interfaces and the route for answering technical queries.

A programme date alone does not make an area ready for installation. The team also needs coordinated information, access to the workface and a sequence that reflects surrounding trades. The points below are useful prompts for a pre-start review rather than a prediction about any particular project.

Common issues to review

  1. Late drawing revisionsA change issued after pricing or mobilisation can affect routes, quantities or the order of work. Keep a clear register of the information released for installation.
  2. Unresolved service interfacesDuctwork may share limited space with structure, pipework, containment and ceilings. Identify who coordinates open clashes and how decisions are communicated.
  3. Access not readyIncomplete areas, restricted routes or missing access arrangements can prevent installation even when labour is available.
  4. Delivery and storage constraintsLarge or fragile components may need planned delivery slots, suitable unloading and protected storage close to the work area.
  5. Trade stackingSeveral trades working in the same zone can reduce productive access. Area-by-area sequencing can make dependencies easier to see.
  6. Technical queries left openQuestions about routes, details or responsibility need a named decision route and realistic response dates.
  7. Handover requirements confirmed lateLabels, photographs, records or assistance with testing should be identified where they form part of the agreed package.

Warning signs before work starts

Multiple drawing sets are circulating without a clear status. The programme shows an installation start but no area release. Access and storage are described only as “to be agreed”. Responsibility for penetrations, insulation, controls or testing is assumed rather than recorded.

One warning sign does not necessarily mean the programme will slip. It does mean the item deserves an owner, a decision and a date.

Build a more useful pre-start review

Bring the current drawings, scope, programme and interface list into one review. Confirm which areas are genuinely available, which decisions remain open and what information the installation team should use. Record changes rather than relying on informal conversations.

For tender-stage preparation, use our ductwork quotation checklist. For package responsibilities, see how to define a ventilation scope before award.

How Cliventa approaches suitability

Cliventa reviews suitable opportunities against the available drawings, specification, scope, location, programme and known site constraints. Installation and handover support are then delivered in line with the package agreed for the project.
