• Compare bids only after scope is aligned

What it is

Architect and engineer roles in commercial projects: who does what is a planning topic. The goal is not to memorize rules. The goal is to make decisions in the right order so the build is predictable.

Why it matters

When this is planned well, your project feels calmer. The schedule becomes easier to protect and the budget becomes easier to control.

Step by step approach

1. Create a test fit layout and confirm accessibility impacts
2. Plan phasing to protect operations and keep access clear
3. Coordinate engineering and life safety early
4. Order long lead items as soon as the permit set is stable
5. Close out with inspections, training, manuals, and warranties
6. Write the business program: people, equipment, brand feel, opening date
7. Confirm lease responsibilities and landlord approval process

Use this list as a decision sequence. Planning time is cheaper than construction time.

Questions to ask

• How will accessibility and life safety be addressed
• How will phasing protect staff and customers if occupied
• What long lead items could affect the opening date
• What closeout documents will I receive for operations
• What is the change order approval rule
• What is the realistic plan review timeline for this scope
• What approvals are required from the landlord and when

Red flags

• Closeout documentation not discussed
• No plan for phasing or occupant safety
• No clarity on lease responsibilities or landlord standards
• Unrealistic opening date with no buffer
• Vague scope with many assumptions
• Long lead items ignored until late

Checklist

• Scope and allowances defined in writing
• Protection plan and communication rhythm set
• Decision calendar created for long lead items
• Existing conditions photographed and measured
• Inspection milestones planned
• Goal and priorities written in one page
• Closeout folder planned for manuals and warranties

Common mistakes

• Approving changes verbally without documentation
• Ignoring lead times for long lead materials
• Skipping protection and cleanup expectations
• Starting work before key selections are decided
• Assuming inspection timing will be instant
• Comparing bids that do not share the same scope
• Overcomplicating design with too many materials
