Construction administration and inspection
The same people who drew it are the ones who watch it get built.
Bidding and award, submittal review, pay applications, change order negotiation, resident inspection and closeout.
Advertisement, bidding and bid tabulation. Preconstruction and progress meetings. Submittal and shop drawing review. Pay application review, change orders, inspection and record drawings.
A set of plans is a prediction. Construction administration is where the prediction meets the ground, and it is the phase where an owner is most exposed if nobody is paying attention on their behalf.
