Long-lead items (hoods, walk-ins, draft systems) that set your opening date

One late item can set the opening date

Most of a buildout can be sped up with more labor or overtime. A hood that has not shipped, a walk-in still in the factory or an installer booked solid cannot. Those items set the date regardless of how fast everything else goes. In 10 Things, In No Particular Order, I Would Keep In Mind Before My Buildout, a writer who moved from restaurants into construction recommends tracking hoods, walk-ins, millwork and specialty equipment as color-coded long-lead items from day one. We read that post via an archive. It is one author's practice, not a study, but it describes a method any project can use.

Installers can be the bottleneck as much as products. In a thread on the most annoying part of building a new restaurant or shop, one owner who had done several buildouts named installing draught lines as a major holdup because only one person in their region did it. Another described fire alarm work delayed because only about three companies did it locally and all were behind. We have controller-supplied excerpts of that thread, not a complete copy, and the regions are not named. They show the pattern this article plans for: a scarce person or product on the critical path.

Which items to treat as long-lead

A long-lead item is anything whose procurement or installation time could exceed the time available once the design is set. Lead times change with the market, the manufacturer and the season, so this list is about categories, not durations. For each item on your project, get the supplier's lead time in writing at the time you order, and ask whether it runs from order, from approved shop drawings or from deposit. Those can be weeks apart.

Include services as well as goods. A suppression contractor, a fire alarm designer, a draft-system installer, a refrigeration technician to start up the walk-in and a balancing contractor can each hold up the end of the job. Count the utility's work too. A gas meter set or electrical service upgrade is outside your contractor's control and should be on the tracker until it is confirmed.

• Hood, exhaust fan and makeup air unit (often made to order; shop drawing approval may come first)
• Walk-in cooler and freezer boxes, condensing units and refrigeration startup
• Custom bar and front-of-house millwork, and specialty countertops
• Specialty or imported cooking equipment, and equipment needing a factory technician to commission
• Draft beer system and its installer, including trunk lines that must run before walls or ceilings close
• Fire alarm design, installation and testing; suppression system and its acceptance test
• Electrical gear such as larger panels or switchgear; utility meter sets and service upgrades
• Exterior signage needing landlord and permit approval

Working backward: need-by, lead time, buffer, order-by

The tracker turns each item into one date the owner can act on. Start with the need-by date: the week the item must be on site, or the installer must be working, so that the next activity can start on schedule. The construction sequence sets it. Walk-in panels usually need to be in place before nearby ceilings, finishes and final refrigeration piping. Draft trunk lines need to be run before the bar and chase close. The hood needs to arrive before duct and roof work can be finished. Then subtract the written lead time and a buffer for shipping, inspection and the inevitable slip. The result is the order-by date, or for a service, the book-by date.

Use the same formula for every item so nobody argues about method: order-by = need-by − lead time − buffer. Choose the buffer by risk. Use more for imported or custom items, items from a supplier you have not used before, and items with a single installer. When an order-by date falls before construction starts, or before permits are issued, the formula is telling you the item is on the critical path from the start.

Hypothetical worked example: a long-lead tracker for one site

All lead times and dates are hypothetical. Site 1's construction starts in week 0, and the target opening is week 20. The owner uses a two-week buffer on every item. The hood and makeup air package is needed on site by week 6 and has a 10-week lead time, so it must be ordered by week −6 (6 − 10 − 2), six weeks before construction starts. The walk-in is needed by week 8 with an 8-week lead time, so it is ordered by week −2. Custom bar millwork is needed by week 12 with a 12-week lead time, so it is ordered by week −2 as well. An imported specialty oven needed by week 14 with a 16-week lead time must be ordered by week −4. The draft installer, booking 6 weeks out, must be booked by week 1 for a week-9 rough-in. The fire alarm vendor needs 10 weeks for design, approval and installation before a week-17 test, so it must be engaged by week 5.

Four of the six dates fall before construction starts. That is common for kitchen projects, and it is the reason this tracker exists. The owner cannot wait for the GC's mobilization meeting to discover that the hood should have been ordered six weeks earlier. Those early orders depend on a finished equipment design and carry the risk discussed below.

Single-source installers, and what happens with two sites

When only one or two firms in a region do a type of work, you are booking their calendar, not just buying their product. Call them during design, explain your sequence, and ask how far out they book and how they handle a job that is not ready on the scheduled day. A missed slot can mean waiting for the next opening, which may be weeks away. Confirm the booking in writing and send an update whenever your dates move. Ask whether they need a deposit to hold the date, and what happens to it if you slip.

Multi-site groups face an extra risk: competing with themselves. Continuing the hypothetical, Site 2 starts construction eight weeks after Site 1, on the same template. Its draft rough-in falls in its own week 9, which is group week 17. Site 1's final draft hookup is also scheduled for week 17, and the region has one installer. The tracker flags the conflict once both sites are on one group calendar. The owner can ask the installer to do both that week, move Site 2's rough-in a week if its sequence allows, or line up a second installer from a neighboring region in advance. Any of these is easier in month one than in week 16.

Ordering early: procurement risk, approvals and substitutions

Ordering before the permit or plan review is complete is a business decision with real risk. If a reviewer requires a longer hood, a different walk-in layout or a change in equipment, an item already in production may need costly changes or may not be usable. Before approving an early order, the owner should confirm the specifications with the designer, have shop drawings checked against the submitted plans, and get the supplier's cancellation, change and restocking terms in writing. A stable design reduces the risk. It is not a regulatory approval.

Substitutions have their own trap. When a long-lead item slips, the tempting fix is a different model that ships sooner. But approvals are often based on specific equipment. In Washington, DC, for example, DC Health's Plan Review Guidance Packet (Dec 2019, ver. 8) asks for manufacturer specification sheets and an equipment schedule with make and model numbers. Its signed statement says any deviation without prior permission from the DC Health food safety division will nullify final approval. A substitution may also change electrical, gas or ventilation requirements. Check with the designer and the relevant agencies before swapping, and keep the written approval.

Delivery, storage and site access

An item that arrives on time but cannot get into the building is still late. For each large item, check the dimensions against door openings, corridors, elevators and turns, and plan how it will be unloaded: loading dock, liftgate, forklift or crane. Walk-in panels and long hoods are the usual problems. If the site is not ready when an item ships, decide in advance where it will be stored, who insures it there, and who pays for storage and redelivery.

Inspect every delivery against the order on arrival, including model numbers, voltage, phase and visible damage. Photograph crates before and after opening, and note concerns on the delivery receipt before signing. Freight damage claims usually depend on prompt notice under the carrier's or supplier's terms. Our article on buying equipment online versus through a dealer covers receiving and freight claims in more detail.

• Item dimensions against the narrowest point of the delivery path
• Unloading method and who provides the equipment or crane
• Storage location, insurance and cost if the site is not ready
• Receiving check: model, voltage, phase, damage, photos, notes on receipt
• Who on site may accept and sign for deliveries

The weekly long-lead review

A tracker only helps if someone updates it. Add a standing ten-minute item to the weekly construction meeting. For each long-lead line, confirm the order date, the supplier's latest ship date and whether it has changed, the delivery and installation dates, and the remaining float between expected arrival and need-by. Ask suppliers for written ship confirmations, not verbal reassurance. When float on any item drops to zero, it becomes a critical-path problem and goes to the top of the meeting.

Keep the evidence. Save purchase orders, written lead-time quotes, shop drawing approvals, supplier change notices, installer booking confirmations, delivery receipts and photos. If a delay later affects rent commencement, a contractor claim or an insurance question, you will need to show when you ordered, what you were promised and when you learned of the slip. For a restaurant group, the actual lead times recorded at each site become the planning figures for the next one, which is better data than any forum estimate.

• Each item: order-by date, actual order date, promised ship date, current ship date
• Float between expected arrival and need-by, highlighted when it drops below the buffer
• Installer bookings confirmed in writing and re-confirmed after any schedule change
• One group calendar across sites to catch shared-installer conflicts
• Substitutions only with designer review and written agency approval where required
