Design-author support helps coordinate design and execution. Define its scope, visits and outputs separately from the design package.
Starting agreement
Provide current drawings, programme, responsible parties and known questions. Agree consultation formats, review milestones and notification procedures before work starts.
Critical milestones
Concealed-work stages matter: foundation insulation, air barriers, windows and service penetrations. The review schedule depends on the design and agreed scope.
Documented output
The current Studio service describes agreed clarifications, review records and a deviation list. Link each issue to its location, drawing revision and closure method.
Responsibilities
Design support does not replace technical supervision, laboratory testing or contractor responsibility. Specialist investigations and independent certification need appropriate specialists and agreements.
Common mistakes
Inviting review after details are covered reduces visibility. Do not equate a photograph with a full inspection or absence of a comment with a guarantee of all concealed work.
| Item | Parameter | Check / result |
|---|---|---|
| Before work | Revisions and schedule | Agreement |
| During work | Details and changes | Records |
| Afterwards | Issue closure | Evidence |
What this means for your project
Coordinate review milestones with the contractor’s programme. Fees and scope should reflect visits, specialist checks and output formats.
