How to Price a Job Where Access Is the Real Unknown

Why this matters

Some jobs are not hard, they are hard to get to. The repair is forty minutes of actual work at the end of a crawl, a ladder, a lift, a locked riser, or three flights with no elevator. When a shop prices that job it usually prices the repair and then adds a vague cushion for "the crawl," and the cushion is either far too small or invisible to the customer, which means it cannot be defended when the job runs long. Access is not a mood, it is a measurable quantity, and it can be quoted as one.

Before anything else: the access itself is the hazard

The route is where people get hurt on these jobs, and the protections belong to the route, not to the repair.

Confined-type spaces first. A crawlspace, a vault, a pit or a tank is a permit-required confined space when it has limited entry and exit, is not designed for continuous occupancy, and holds a recognized hazard such as an oxygen-deficient or flammable atmosphere or an engulfment risk, and entry by your employees under those conditions is governed by 29 CFR 1910.146, which means atmospheric testing, an attendant and a written permit before anyone goes in, not a flashlight and a good attitude.

Airborne exposure is the route hazard that gets skipped. Disturbing loose-fill or fibrous insulation, or working in a space carrying rodent droppings and nesting material, is an inhalation route, and an inhalation route needs a respirator selected and fit-tested under a written program per 29 CFR 1910.134 with fit testing at least annually under 1910.134(f)(2), not gloves and safety glasses. Where an attic runs hot, the control is a work and rest cycle with water and a cooler recovery area, and a second person who can see the first.

Height last, because both Parts have a home and the scope decides which is yours. Residential construction work at 6 feet or more above a lower level is 29 CFR 1926.501(b)(13); general industry walking-working surfaces trigger at 4 feet under 29 CFR 1910.28(b)(1)(i). Know which Part your job falls under before you quote a roof or a ladder-fed attic, because the control you have to price differs.

Step 1: Prove access is actually the driver

Do the arithmetic before you build a whole instrument for it. Split the estimated hours into hours spent working on the equipment and hours spent getting to, positioning at, protecting, and returning from it. If the second bucket is under about a sixth of the total, access is a normal overhead and your standard rate absorbs it. Once it passes roughly a third, access is the job and the price has to say so.

Skipping this step is what produces the shop that adds an access surcharge to everything and slowly prices itself out of easy work.

Step 2: Measure access in the unit it varies in

An access multiplier that is not tied to a measured condition is a feeling. Pick the one dimension that actually changes your productivity on this job type and record it:

• clear working height at the work position, in inches
• traverse distance from the truck to the work position, in feet, and the number of times a person must make it
• whether tools and material can be carried in one trip or staged
• the number of doors, hatches, gates or keys between the truck and the work
• whether the path is obstructed by stored goods and who owns the goods

One or two of these dominate on any given job type. Recording all five for a season is how you learn which.

Step 3: Derive the multiplier from your own records, and state the geometry it came from

A multiplier is only valid inside the conditions it was measured under, and that clause has to travel with the number every time you use it. Say the shop's last nine jobs of a given type show that tasks taking 1.0 hour in open standing space took about 1.6 hours in the crawl. That 1.6 was measured at clear working heights between 24 and 36 inches with a clear path, and it does not survive outside that band: the same records show heights below 24 inches running nearer 2.4, because at that point the tech is on their side rather than on their knees and every tool change costs a repositioning.

Write the multiplier into your estimating notes with its band attached, not as a bare number. A 1.6 quoted onto an 18-inch crawl is a 50 percent shortfall on the restricted portion of the work, and it will look like a bad estimator rather than a misapplied constant.

Step 4: Price access as its own line

Two lines, not one blended number. The work line carries the productive hours at open-space productivity. The access line carries the fixed access overhead (setup, protection, staging, traverse) plus the productivity penalty on the portion of the work that actually happens in the restricted zone.

This is not cosmetic. A customer who sees an access line can act on it, a customer who sees a single inflated number can only shop it. It also means that when the access assumption fails, you are adjusting one identified line rather than reopening the whole price.

Step 5: Write the access assumption with a Boolean, a unit and a step

The assumption is the load-bearing sentence in the whole quote. It needs four parts: what is assumed, how it will be measured, the Boolean if there is more than one condition, and what the price does when the assumption fails.

A workable form: this price assumes clear working height of 24 inches or more at the work position, measured with a tape at the position, and a path clear of stored goods. If either condition fails, and either alone is enough, the restricted portion of the work re-rates in one step from the standard access multiplier to the low-clearance multiplier, and the customer is told the new hour figure before work continues.

One step, not a sliding scale. A continuously variable adjustment invites an argument about inches on the day, and it cannot be verified after the fact.

Step 6: Hand the customer the lever

Every access assumption should come with the thing the customer can do to make it true. Clear the path. Move the stored goods off the run. Have the gate code, the riser key, and the parking arrangement ready at the arrival time rather than sourced during it. Give them a concrete acceptance test rather than a request: a clear walking route wide enough for a person carrying a tool bag, from the door to the equipment, with nothing to step over.

Customers who are handed a lever usually pull it, and a job that arrives with the path cleared costs less than the one where your crew moves somebody's storage and is then responsible for it.

Worked example: six hours of work behind a crawl

Base scope, priced at open-space productivity: 6.0 labour hours. Of those, 2.0 hours happen at an accessible position and 4.0 happen inside the crawl.

The access line has two components. The fixed overhead - protecting the entry, staging tools, the traverses in and out - runs 1.2 hours from the shop's own records on this job type. The productivity penalty applies only to the 4.0 restricted hours, at the 1.6 multiplier derived for clear heights of 24 to 36 inches, so 4.0 becomes 6.4 hours, a penalty of 2.4 hours.

Total quoted labour: 2.0 plus 6.4 plus 1.2, which is 9.6 hours. Against the naive 6.0-hour read of the same work, that is 60 percent higher. Access accounts for 3.6 of the 9.6 hours, or roughly 38 percent of the quoted labour, which clears the one-third mark from Step 1 and confirms access is genuinely the driver on this one rather than a rounding factor.

Now the assumption fails. The crew arrives, tapes the working height at the equipment, and reads 19 inches. Below the 24-inch gate, so the low-clearance multiplier applies to the restricted portion: 4.0 hours at 2.4 gives 9.6 hours in the crawl. New total: 2.0 plus 9.6 plus 1.2, which is 12.8 hours. That is 3.2 hours more than the 9.6 quoted, an increase of about 33 percent, and it is a single identified adjustment on one line rather than a renegotiation of the job.

Notice what did not change. The productive work is still 6.0 hours of work in open-space terms and the customer is not being told the repair got harder. The condition that changed is measured, was named in writing before anyone drove out, and has one stated consequence. That is a conversation that takes four minutes on a doorstep.

Notice also what would flip the recommendation. If the shop's records showed the crawl multiplier bouncing between 1.2 and 2.8 with no relationship to measured height, the multiplier is not a function of height and the honest instrument is not a re-rate gate at all, it is an hourly arrangement for the restricted portion with a not-to-exceed ceiling. A gate is only defensible when the measured condition actually predicts the hours.

Verify the multiplier instead of trusting it

Access numbers rot faster than repair numbers because they depend on the building stock you happen to be working in this year.

Record two figures on every job of the type: quoted access hours and actual access hours, where actual means from the moment a tech leaves the truck for the route to the moment they are productive at the equipment, plus the return. Techs will not record this unless the field form has the two timestamps on it, so put them there rather than asking for a memory at the end of the day.

Review on a median of at least five completed jobs of the same type, never on one. If the median actual exceeds the median quoted by more than about 15 percent of the quoted access hours, correct the multiplier by half the observed median gap, not the whole gap. Half gain is deliberate: full-gain correction on a small sample is how an estimating template oscillates for a year without ever settling, over-correcting on a bad run and back again on a good one.

And check the direction on the outliers before you touch anything. One job in the sample running double is a different diagnosis from five jobs running 20 percent long. The first is usually a condition nobody wrote down, which is a register problem, not a multiplier problem.
