Category: Price vs Time

In a fast-track approach, construction begins before design is fully complete. Foundations of the schedule — demolition, structural work, MEP rough-in paths — start while finish details are still being drawn. Procurement of long-lead items happens off preliminary drawings.

• Best when: the move-in date is fixed and expensive to miss — a lease expiration, a store opening tied to a season, a merger deadline.
• The cost: a premium of roughly 5–15%, less competitive bidding, and a real chance of rework when late design decisions conflict with work already in place.
• What it demands: an owner who can make finish and layout decisions quickly and stick to them.

Phased: build in deliberate stages

Phased construction divides the space into zones and completes them in sequence, often so the tenant can keep operating in part of the space or move in progressively.

• Best when: you occupy the space during construction, cash flow is better spread out, or only part of the build-out is time-critical.
• The cost: total duration is longer, and mobilizing trades multiple times adds 3–8% versus doing everything at once.
• What it demands: careful dust, noise and life-safety separation between finished and active zones.

A simple way to choose

Ask two questions. First: is my move-in date firm and costly to miss? If yes, fast-track earns its premium. Second: do I need to operate in the space while work continues? If yes, phased is almost unavoidable. Many mid-size projects land in the middle — a fast-tracked first phase for the space you need now, and a relaxed schedule for the rest. The right answer is whichever one you chose on purpose.

Once you have accepted that price and time pull against each other, the next decision is how you want to manage that tension across the life of the project. Two strategies cover most commercial tenant improvements: fast-track and phased. They are not better or worse — they serve different priorities.

Fast-track: overlap everything

The right answer is whichever one you chose on purpose.

The honest answer is “between 8 and 20 weeks of construction, plus 4 to 12 weeks before that for design and permitting.” The range is wide because tenant improvements are not standardized products. But the phases are predictable, and knowing them helps you tell a realistic schedule from an optimistic one.

A typical timeline for a 5,000–8,000 sq ft fit-out

• Weeks 1–4 — Design & documentation. Space planning, finish selections, MEP engineering, permit-ready drawings.
• Weeks 3–8 — Permitting. Runs partly in parallel with design. Plan-check turnaround varies from days to two months by jurisdiction.
• Weeks 1–6 — Long-lead procurement. HVAC equipment, electrical switchgear, glass, and custom millwork ordered as soon as drawings allow.
• Weeks 8–10 — Demolition & rough-in. Selective demo, framing, overhead MEP rough-in, inspections.
• Weeks 11–14 — Drywall, finishes & millwork. Hang and finish drywall, paint, flooring, ceilings, casework.
• Weeks 15–17 — Trim-out & commissioning. Devices, fixtures, doors and hardware, balancing HVAC, final inspections.
• Week 18 — Punch list & certificate of occupancy.

The four things that add weeks

1. Landlord approvals. Work letters, insurance, and building-standard sign-offs can quietly eat two to three weeks. Start them the day the lease is signed.
2. Long-lead equipment. A rooftop HVAC unit at 10–16 weeks will set your schedule regardless of how fast the trades move.
3. Permit revisions. One round of plan-check comments is normal; budget for it rather than being surprised by it.
4. Change orders mid-build. Every added scope after demolition ripples through every trade that follows it.

Can it go faster?

Yes — a design-build team that overlaps permitting with early procurement and runs a two-shift schedule can deliver the same space in 10–12 weeks of construction. It costs more, and it depends on the landlord and the jurisdiction cooperating. The key is to decide you want the fast track before design starts, not after demolition is done.

On paper a commercial tenant improvement looks like a fixed thing: a set of drawings, a price, a completion date. In practice it is a dial. Turn it toward speed and the price climbs — overtime crews, expedited submittals, air-freighted materials, premium subcontractor scheduling. Turn it toward price and the calendar stretches — you wait for the standard lead time, the one crew, the next inspection slot. Neither direction is wrong. The mistake is turning the dial without knowing which way you turned it.

The three levers

• Scope — how much you are building, and to what finish level.
• Budget — the dollars available, including the contingency you are willing to spend to protect the date.
• Schedule — the day you need to move in, and how firm that day really is.

Fix any two and the third is decided for you. A tenant who fixes scope and schedule has chosen to let budget float. A tenant who fixes scope and budget has chosen to let the move-in date float. Good contractors say this out loud on day one; the trouble starts when everyone assumes all three are locked.

What speed actually buys

Acceleration is real and it works — but it is not linear. The first few weeks of schedule compression are cheap: better sequencing, an earlier permit submission, ordering long-lead items before drawings are 100% complete. The last two weeks are expensive: second shifts, weekend inspections, and paying subs a premium to leave another job. A rough rule from our projects is that shaving 10% off a schedule costs 3–5% more; shaving 25% off can cost 15–20% more and sharply raises the risk of rework.

What patience actually buys

When the move-in date has genuine slack, that slack is worth money. You can competitively bid long-lead packages instead of sole-sourcing them. You can accept standard 6–8 week lead times on storefront glass and custom millwork instead of paying to jump the queue. You can schedule inspections in the normal rotation. On a typical 6,000 sq ft office fit-out, a tenant with four extra weeks of float often lands 8–12% under the fast-track number for identical scope.

How to decide before you sign

1. Write down your true move-in date and what happens if it slips a week. If the honest answer is “not much,” you have budget-saving room.
2. Ask your contractor for two schedules — standard and accelerated — with the price difference broken out line by line.
3. Identify the long-lead items (HVAC units, switchgear, glass, millwork) and decide early whether to pre-order.
4. Set a contingency specifically labeled “schedule protection” so everyone knows what it is for.

Price versus time is not a problem to be solved once. It is a conversation you have at every milestone. The tenants who finish happy are the ones who kept having it.
