A pre-demolition power checklist covers six things: who verified the utility disconnect, what loads the crew will run, which generator size and voltage fits those loads, where the unit sits and how it gets fuel, how power is distributed and protected, and when the rental starts and ends. Each item has an owner, and the superintendent should know the name beside every line before the first shift. Skipping one tends to surface as a stopped crew or a late truck, not as a paperwork problem.
The disconnect comes first because everything else depends on it. OSHA’s demolition standard, 29 CFR 1926.850, states that electric and other service lines must be shut off, capped, or otherwise controlled outside the building line before demolition starts, and that any utility company involved must be notified in advance. Once the building loses utility power, the site runs on temporary power, and that is where a diesel generator rental enters the plan. What follows is organized by checkpoint, not by hour of the job, so you can hand each group to the person who owns it.
Stag Power Rentals supplies diesel generators from a yard in Dickinson, TX, with a fleet running from 20 kW to 2000 kW. For a broader look at how power is staged across a teardown, see the demolition site generator rental guide. For a job inside a standing building, see generator planning for interior selective demolition. This page stays on the checklist itself.
Before mobilization: paperwork and sizing
Three items belong here, and none of them needs a truck on site. The first is the disconnect record: which utility was notified, what was shut off or capped, and the name of the person who verified it. Confirm the exact requirements with your safety lead, since they depend on the contract, the jurisdiction and the structure.
The second is the load list. Write down every tool, light plant, pump, dust control unit and trailer that will draw power, with its voltage and whether it starts under load. The sizing guide and load list walks through building that list and turning it into a generator size. Demolition loads often change as the work moves from interior strip-out to the structure, so note which phase each load belongs to.
The third is voltage and phase. Match the generator output to the equipment you listed, and flag anything that needs a different voltage than the rest. A short call with your rental provider at this stage is cheaper than finding a mismatch on the pad.
On arrival: placement, fuel and ground protection
Walk the placement before the unit is set. A generator on a demolition site needs stable ground, clearance from the structure being taken down, and a route that delivery and fuel trucks can use without crossing debris paths. Ask who owns that decision on your site, since it is usually the superintendent working with the safety lead.
Fuel is the second arrival item. Decide whether the unit will be refilled from a supply truck or paired with an extended-runtime tank, and name the person who owns refueling. If the job will run long hours, the fuel tank rental option is worth pricing against repeated refills. Diesel is the only fuel to plan around, so confirm storage and spill rules for your site before the tank arrives.
Ground-fault protection and distribution come next. Temporary power on a wet, dusty site needs protection at the point where crews plug in, and cords should be routed away from equipment paths. Stag’s power distribution equipment covers moving power from the generator to the work area; your electrician decides what protection each circuit needs.
Before the first shift: the confirmation table
The table below pulls the main items into one sheet a superintendent can sign off at the morning briefing. Each row names who normally confirms the item and why it matters. Treat the “who” column as a starting point, because your contract and site roles may assign these differently.
| Checklist item | Who confirms | Why it matters |
|---|---|---|
| Utility disconnect status and verifier’s name | Superintendent with the safety lead | Crews should not start work on a structure whose service status is undocumented |
| Load list by phase of work | Superintendent or foreman | Sets the generator size and shows which loads start under load |
| Generator size and voltage | Rental provider with the electrician | A mismatch stops tools and can damage equipment |
| Placement and truck access | Superintendent | Keeps the unit clear of the work zone and reachable for service |
| Distribution and ground-fault protection | Site electrician | Protects crews from shock hazards on wet, dusty ground |
| Lighting coverage | Safety lead | Early and late shifts depend on it |
| Refueling owner and schedule | Superintendent | A dry tank stops the whole crew |
| Rental start and end dates | Project manager | Billing follows the shift pattern, so dates should match the schedule |
Go through the table out loud at the first briefing. Anything left blank is the day’s first task, not something to carry into the shift.
Lighting and shift pattern
Lighting is easy to leave off a power list because it feels secondary. On a teardown with early starts or night work, light towers and work lights can account for a meaningful share of the generator load, so include them in the load list. Your shift plan also affects cost: Stag bills by single, double or triple shift, so the number of shifts you expect should be stated when you request a quote. The pricing guide explains the factors that move a rental quote. To carry these items into a bid, see how a demolition bid should account for temporary power.
At demobilization: the exit plan
The exit plan belongs on the checklist before the job starts. Agree on the planned end date, who calls the rental provider when work finishes early or runs late, and who confirms that cords, distribution gear and any fuel tank are accounted for. Decide how the unit will be shut down and made safe before pickup, and who signs off on it. A clear end date matters because rental billing depends on it.
Working through the checklist
The order matters more than the format. Confirm the disconnect, size the power, place and fuel the unit, protect the distribution, light the work area, and set the end date. If a step cannot be confirmed, write down who will confirm it and by when.
If time is short, the list below holds the items most likely to stop a crew when they are missed. It is a summary of the groups above, ordered by how early each one needs an answer. Treat it as the short version for the pre-job meeting, and keep the full table for the sign-off. Your safety lead can add or reorder items to match the contract and the site.
- Utility disconnect status confirmed in writing, with the verifier’s name and the utility notified.
- Load list finished, with voltage, phase and any loads that start under load.
- Generator size and voltage matched to that list.
- Placement and truck access walked and approved.
- Refueling owner named, with a schedule for diesel delivery or an extended-runtime tank.
- Distribution and ground-fault protection reviewed by the site electrician.
- Lighting included in the load list for early and late shifts.
- Rental start date, end date and shift pattern agreed, with an exit plan owner.
Close the gaps with a quote request
If your checklist has open items on size, voltage or fuel, Stag can work through them with you from the Dickinson yard. Start with the construction industry overview to see how generator rental fits other job types, then send the load list and shift plan through the quote request form. Bring the disconnect record and your expected start and end dates, and the quote can reflect the job as you have planned it.
Frequently Asked Questions
What is the first power item to confirm before demolition?
Confirm the utility disconnect status and who verified it. OSHA 1926.850 calls for service lines to be shut off, capped or otherwise controlled outside the building line, with the utility notified in advance. Confirm details with your safety lead.
How do I choose a generator size for a demolition site?
Start with a load list of every tool, light and pump, including voltage and starting demand. The total, with room for loads that start under load, drives the size. Stag’s fleet spans 20 kW to 2000 kW.
Who should own refueling?
Name one person on the superintendent’s team before the unit arrives. A fuel schedule with a clear owner prevents a dry tank during a shift. An extended-runtime tank can reduce refill trips, depending on the job.
How is a generator rental billed?
Stag bills by single, double or triple shift. State your expected shift pattern when requesting a quote, since it affects the price.
What belongs in the exit plan?
The planned end date, who calls the provider if the schedule changes, and who confirms that gear and fuel equipment are accounted for before pickup.
