Construction Administration (CA)
The phase after precon, where the design team keeps the built project honest to the drawings.
Quick Answer
Construction Administration (CA) is the phase where the architect and engineer support the project during actual construction — reviewing submittals and shop drawings, answering RFIs, observing site progress, and certifying pay applications and completion. It follows preconstruction and runs until closeout. CA is a design-team service, distinct from the contractor's own field operations.
The Full Picture
A design isn't finished just because construction has started — questions come up, products need verifying, and the built project needs to stay aligned with what was drawn and specified. Construction Administration exists because the design team stays engaged through the build, interpreting intent and checking conformance rather than handing off drawings and disappearing.
A typical CA scope, following the structure used in standard AIA owner-architect agreements, includes periodic site visits and general observation of progress (not exhaustive daily inspection), reviewing submittals and shop drawings, responding to RFIs, reviewing and advising on change orders, and ultimately certifying substantial completion, conducting the punch walk, and certifying pay applications along the way.
During CA, an architect might review a curtain wall shop drawing submittal, respond to an RFI flagging a conflict between that submittal and a structural detail, and months later certify substantial completion once the resulting punch list is closed out — each a distinct CA task tied to keeping the built work faithful to the design intent.
CA is literally the phase that follows preconstruction, and precon's quality shows up directly in how CA goes. A budget, schedule, and scope well-defined in precon gives CA a stable baseline to protect. Coordination issues, spec gaps, or ambiguities that precon's document review didn't catch resurface during CA as RFIs and change orders — at a higher cost than catching them earlier would have been.
Real Examples
Common Misconceptions
People assume: People assume CA means the architect is managing the jobsite.
Actually: CA is design-team oversight and conformance review, not field management — the general contractor's own superintendent and project team run means, methods, and daily site operations.
People assume: People assume CA ends at substantial completion.
Actually: it usually continues through punch list completion, final pay application certification, and closeout document review — O&M manuals, as-builts, warranties — up to final completion.
Frequently Asked Questions
What is Construction Administration in construction?
It's the phase where the architect and engineer support the project during construction — reviewing submittals, answering RFIs, observing site progress, and certifying pay applications and completion — following the standard scope in most owner-architect agreements.
What tasks does the architect do during CA?
Periodic site observation, reviewing submittals and shop drawings, responding to RFIs, reviewing change order requests, and eventually certifying substantial and final completion, including the punch list process.
Is Construction Administration the same as project management?
No — CA is a design-team service focused on design conformance and interpretation. Construction and project management is the contractor's role, running the actual means, methods, schedule, and field operations.
When does Construction Administration start and end?
It starts once construction begins, following preconstruction, and typically runs through final completion — including submittal review, RFI response, substantial completion, punch list, and closeout document review.
How does preconstruction quality affect the CA phase?
Issues not caught during precon's document review and coordination — spec gaps, drawing conflicts — resurface during CA as RFIs and, often, change orders, usually at a higher cost than catching them earlier would have been.
