Design Coordination: Interfaces, Detail Reviews and Open Items

The first step is to define the area under review and the current information set. Architectural, structural and services drawings are considered alongside available site information. Conflicts between documents of different dates are recorded, with the reviewed versions identified. A coordination study needs a known information base before its conclusions can be useful.

A study can focus on a defined package such as a ceiling zone, stair junction, wet area or fitted-furniture interface. Questions requiring specialist input are directed to the relevant discipline. Connected decisions are considered together, while each discipline's technical responsibility remains identified within the agreed team structure.

A detail review considers material transitions, installation sequence, maintenance access and dimensional relationships between trades. A ceiling drawing, for example, is read alongside lighting, ventilation and access-panel positions. Where a measurement or product specification is missing, the required input is requested before the detail is treated as resolved.

An open-item record identifies the location, relevant drawing, decision required, responsible reviewer and current status. The record tracks which revision incorporates an agreed decision. Defined review points help prevent the same question from being reopened across different files; items that remain unresolved are made explicit at handover.

To discuss coordination support with Koloni, share the package to review, team contacts, available documents and target dates. Design review, site visits, construction management and fabrication approval are different tasks. The agreement identifies the included duties, point of contact and delivery records before work begins.
