What general design is
The essence
Section titled “The essence”Designing a building takes many disciplines: architecture, structure, mechanical, electrical, fire, energy, and sometimes transport, landscape and acoustics.
There are two routes:
The client coordinates
Section titled “The client coordinates”They contract with each discipline separately and have to pull the work together. That takes professional knowledge and time — a client generally has neither.
General design
Section titled “General design”One party takes on the whole package: it contracts with the disciplines or has its own team, coordinates them, and stands before the client as one responsible party.
What it covers
Section titled “What it covers”- aligning the disciplines and holding the design programme,
- ensuring the consistency of the drawings,
- assembling the documentation for the authority procedures,
- preparing the client’s decisions,
- design input during construction, where that is part of the appointment.
Why it works better
Section titled “Why it works better”One responsible party
Section titled “One responsible party”If the services do not fit in the structure, that is not the client’s problem.
Clashes found earlier
Section titled “Clashes found earlier”The disciplines’ drawings are produced together, not one after another. Contradictions come out at the drawing board.
One programme
Section titled “One programme”The disciplines wait on one another; if nobody organises that, the project moves at the pace of the slowest.
Unambiguous documentation
Section titled “Unambiguous documentation”From one hand, in one system, without contradictions.
The boundaries of responsibility
Section titled “The boundaries of responsibility”The general designer does not take over the professional liability of the individual disciplines: every drawing is signed by the qualified designer of that discipline. What they undertake is consistency and coordination.
That has to be recorded precisely in the contract. Boundaries of responsibility.
When it is especially valuable
Section titled “When it is especially valuable”- for a prefabricated structure, where the design fixes early,
- for a building with complex services,
- under a tight programme,
- where the client has no technical staff of their own.
The point
Section titled “The point”General design does not mean more drawings but fewer contradictions. Its value lies in the mistakes that never happen.
