Question 1

How long does a commercial build-out take in Metro Detroit?

Accepted Answer

A typical commercial tenant build-out in Metro Detroit takes 8–16 weeks from permit to occupancy. Simple office build-outs can finish in 6–8 weeks. Complex spaces like medical offices, restaurants, or dental practices take 12–20 weeks due to specialized MEP, equipment, and inspection requirements.

Question 2

How long does commercial new construction take?

Accepted Answer

Ground-up commercial new construction in Michigan typically takes 6–18 months depending on building size, complexity, and site conditions. A 5,000 sf retail space may take 6–8 months. A 20,000+ sf medical or multi-tenant building may take 12–18 months.

Question 3

What are the main phases of a commercial construction project?

Accepted Answer

The main phases are: Preconstruction (2–6 weeks) — design, budgeting, permitting; Site Work (2–8 weeks) — demolition, grading, utilities; Structural (4–12 weeks) — foundation, framing, shell; MEP Rough-In (3–6 weeks) — mechanical, electrical, plumbing; Finishes (4–8 weeks) — drywall, flooring, paint, fixtures; Final Inspections & CO (1–2 weeks).

Question 4

What causes delays in commercial construction?

Accepted Answer

Common delay causes include permit processing times, weather (especially for exterior work in Michigan winters), material lead times, change orders, unforeseen site conditions (asbestos, structural issues), and inspection scheduling. Experienced GCs build contingency into schedules to absorb minor delays.

Question 5

Can I fast-track my commercial construction project?

Accepted Answer

Yes. Fast-track construction overlaps design and construction phases, starting site work and structural before finishes are fully designed. Design-build delivery is ideal for fast-tracking. Sheker Construction regularly delivers fast-track projects for clients with tight opening deadlines.

Question 6

How does weather affect construction timelines in Michigan?

Accepted Answer

Michigan winters can delay exterior work — concrete pours, roofing, and site work — from December through March. Interior work continues year-round. Starting exterior phases in spring or summer minimizes weather risk. Experienced contractors plan schedules around seasonal constraints.

Question 7

How long does the permitting process take in Oakland County?

Accepted Answer

Simple tenant build-out permits in Oakland County municipalities typically take 2–4 weeks. New construction with site plan review can take 6–12 weeks. Municipalities like Troy, Birmingham, and Bloomfield Hills have established commercial review processes. Your GC should submit plans early to avoid delays.

Question 8

What is a construction schedule and how detailed should it be?

Accepted Answer

A construction schedule is a timeline showing every phase, milestone, and inspection from permit to Certificate of Occupancy. A good GC provides a detailed Gantt chart with weekly milestones, identifies the critical path, and updates the schedule regularly. Ask for this before signing any contract.
