- Good communications with contractor & building officials.
Is architect responsible for exhaustive inspections, construction methods or construction safety?
No, but he should understand workplace safety and practice “due diligence” on site.
Why would the architect go to site?
- field review
- site meetings

- observe testing
- review samples / mock ups
- meet with consultatns, contractor, client re progress
- determine % work completed (prepare Certificate)
What is the Contractor responsible for? (6)
- construction schedule
