For a small construction company, a first AI consulting project costs about $4,000 to $8,000, planning on five to six consultant days at $750 to $1,250 a day: an audit, site-data rules, one automation and a handover. One construction advisory firm quotes $15,000 to $30,000 for an assessment alone, aimed at firms of 20 to 200 staff.
Three things stretch that range. One is the day rate: goLance's bands run from $65 to $200 an hour for mid-level to senior AI consultants, while a construction-focused advisory page quotes $150 to $350. Another is trying to automate two or three jobs at once. The last is the hours your foremen and office staff spend testing, which no proposal lists. Six days at $2,000 is $12,000; six at $750 is $4,500.
What vendor pages quote, and why a 14-person firm shouldn't copy it
Search for this topic and the construction-focused advisory pages that turn up are written by firms selling to mid-sized contractors. Their numbers are quotes for a different buyer, which makes them a useful ceiling and a poor budget.
| Source | Written for | Readiness assessment | One workflow | Hourly rate |
|---|---|---|---|---|
| Phos AI Labs, advisory cost for construction firms (August 2026) | Construction firms; figures most specific for 20 to 200 employees | $15,000-$30,000 over 3 to 6 weeks | $25,000-$60,000 for a single use case such as an AI estimating review | $150-$350 for an independent consultant |
| Dan Cumberland Labs, AI consulting for construction (August 2026) | Construction companies, from a small-business pilot to mid-market programmes | $15,000-$30,000 over 2 to 4 weeks, credited to a third firm | $10,000-$50,000 over 2 to 4 months for a small-business pilot on one workflow, credited to another firm's pricing guide | $200-$350, credited to the same pricing guide |
| goLance rate guide (updated October 2026) | AI consultants of every kind | Not priced | Not priced | Mid-level $65-$120; senior $120-$200 |
Two points about those figures. The two construction pages repeat the same $15,000 to $30,000 band and one credits it to a third firm, so they are closer to one data point than two. And Phos says its own consulting practice serves companies with revenue of $5 million and above; a fourteen-person building firm is below that. Read the figures as the price of a programme: a workflow review, a data audit, a technology-stack review, a team-readiness check and a prioritised roadmap, which is what Phos lists for its assessment. A small firm's first project needs a decision on one job and a way to run it.
The day rate is the other gap. Phos' hourly band for an independent consultant, $150 to $350, is $1,200 to $2,800 over an eight-hour day. goLance's mid-level and senior bands, $65 to $120 and $120 to $200 an hour, are $520 to $960 and $960 to $1,600. They measure different things: goLance prices AI consultants of every sort, Phos prices construction-focused advisers selling programmes. Three planning rates carry through the rest of this tutorial: $750 and $1,250 a day, the rounded midpoints of goLance's two bands, and $2,000 a day, the midpoint of Phos' band. They are assumptions for reading quotes, not market averages: none of these pages surveys what small builders pay, and each firm's figure is its own price.
Six days at $2,000 is $12,000, the top of the planning range here for a construction specialist on a first project. If a quote lands near $25,000 for one workflow, ask for the days and deliverables line by line. The same two pages put a single-workflow project at $10,000 to $50,000 (labelled a small-business pilot) and $25,000 to $60,000 (a use case such as estimating review), and a fourteen-person firm's first workflow is rarely that big.
A first project in three gated phases, priced in days
The cheapest protection in a first project is the right to stop. Splitting the work into three phases, each ending in a gate, means the firm commits $750 to $2,000 before it commits anything else.
| Phase | What happens | Days | At $750 | At $1,250 | At $2,000 |
|---|---|---|---|---|---|
| 1. Audit and ranking | The consultant reads about 40 recent quotes or site logs, interviews the owner, the office manager and a foreman, and ranks jobs by hours lost and risk. Gate: build, change the job, or stop | 1 | $750 | $1,250 | $2,000 |
| 2. Rules and build | Half a day writing the site-data rules, then three days building and testing on your own documents. Gate: see it working on your own quotes or logs before paying for phase 3 | 3.5 | $2,625 | $4,375 | $7,000 |
| 3. Handover and check | One day teaching the people who will use it, with a one-page card, and half a day a month later to check usage and fix what drifted | 1.5 | $1,125 | $1,875 | $3,000 |
| Total | 6 | $4,500 | $7,500 | $12,000 |
Write the gates into the quote. After phase 1 the firm receives the ranking in writing and can stop having paid for one day. Before phase 3 it has seen a working build on its own documents. Phase 1 is also the cheapest purchase on its own: most of the value of an assessment is knowing which job to build first, and one day at $750 to $2,000 gets that for a small firm. A consultant who will not split the work is selling the whole programme whatever the audit finds.
At the end of the six days the firm should hold seven things it can open without the consultant: the ranked list, the signed site-data rules, the working log or sheet, the instructions written out as plain text, the test results from the firm's own documents, the one-page card for the people who run it, and a short note from the 30-day check saying what changed. If any of the seven is missing from a quote, ask where it is.
Five first projects for a builder, each with its payback test
Every project below shares the three foundation days from the table (audit, rules and handover, check) and adds its own build time. The last column is the test to apply to your own firm: what has to be true for the price to come back. All the figures in it are illustrative assumptions, so replace them with yours.
| First project | Build days | Total days | Price at $750 and $1,250 | Pays back if |
|---|---|---|---|---|
| Quote follow-up and enquiry triage | 3 | 6 | $4,500 to $7,500 | It wins one or two extra jobs a year. At a $38,000 average job and 20% gross margin, one job earns $7,600 |
| Daily site logs from voice notes and photos | 3 | 6 | $4,500 to $7,500 | It saves about 4.7 hours a week of log writing. At $42 an hour that is about $196 a week, so the price comes back in 23 to 38 weeks |
| Supplier and subcontractor quote comparison | 2.5 | 5.5 | $4,125 to $6,875 | It catches one missed scope item a year worth $3,000 or more. Time alone, 2.5 hours on each of 16 tenders, is 40 hours or about $1,700, which will not cover it |
| Variation and change-order log | 2 | 5 | $3,750 to $6,250 | It recovers one unbilled variation a month averaging $600, which is $7,200 a year |
| Subcontractor paperwork chasing | 3 | 6 | $4,500 to $7,500 | The time saved is small, perhaps five hours a month. The return is catching an expired insurance certificate before a subcontractor starts, so price it against your insurer's requirements rather than hours |
Rows one and four are tests of revenue, rows two and three are tests of time and risk, and row five is a test of exposure. Pick the project whose test you can honestly believe about your own firm. A firm that cannot say how many of last year's quotes went quiet, or how many variations were never billed, should buy the audit first and let it produce the numbers; picking the first job by hours lost and risk shows how to count them yourself.
Worked quote: chasing quotes for a fourteen-person building firm
Take a firm of fourteen: the owner, who also estimates, an office manager, a part-time bookkeeper, four foremen and seven tradespeople. It sends about 14 quotes a month, wins about 5, and averages $38,000 a job at a 20% gross margin. Each job earns about $7,600. Every figure here is illustrative.
Phase 1. The audit reads the last quarter's 42 quotes. Suppose 15 were won, 12 were lost with a reason, and 15 went quiet, and 11 of those 15 never had a second contact after the first week. Across a year that is about 44 quotes nobody chased. The ranking puts quote follow-up first because the hours are small, the data already exists in one place and the cost of a wrong draft is an awkward email, not a safety problem.
Phase 2. The build is a quote log (a sheet, or the CRM the firm already has) with a next-action date on every row. It adds a rule for when a quote is due a nudge (day 3, day 10 and day 24), a Monday list of what is due, and instructions in a Project that draft each follow-up from the log row and a summary of what the quote includes and excludes. The owner reads and sends every draft from their own email. Automatic sending is a later decision, after a month of reading drafts.
Phase 3. The handover is a 90-minute session with the owner and office manager on last month's real quotes, plus a one-page card with the Monday routine and the rules. The 30-day check counts how many due follow-ups were actually sent and how many replies came back.
| First-year item | At $750 a day | At $1,250 a day | At $2,000 a day |
|---|---|---|---|
| Consultant, six days | $4,500 | $7,500 | $12,000 |
| Staff time: owner 5 hours at $70, office manager 8 hours at $40 | $670 | $670 | $670 |
| Two assistant seats at $20 a month, annual billing | $480 | $480 | $480 |
| First-year total | $5,650 | $8,650 | $13,150 |
| Extra jobs needed to break even, at $7,600 each | 1 | 2 | 2 |
The test is whether two extra jobs a year, out of roughly 44 quotes that currently go quiet, is believable. Two is about 4.5% of them. If the owner's honest answer is no, a different row of the table is the better first project. After year one the running cost is the $480 for seats and about ten minutes a week for the Monday list.
One draft, with the fixes a person has to make
This is the kind of prompt the phase 2 build puts into the Project's instructions, filled in with one row from the quote log.
You draft follow-up emails for a small building firm, written in the first
person as the owner, in plain friendly language, three to five sentences.
Never change the price, never offer a discount, never promise a start date
or a validity period that is not in the quote details, and never mention
other clients. If a detail is missing, say which one instead of guessing.
QUOTE DETAILS
Client: [first name]
Job: single-storey rear extension with a new kitchen opening
Quote sent: 14 days ago
Amount: $41,500
Included: structure, roofing, windows, first-fix electrics and plumbing
Excluded: kitchen units, flooring, decoration
Last contact: site visit; client asked about the build programme
Purpose: ask if they have questions and offer a short callA realistic first output (illustrative) reads: 'Hi [first name], I wanted to check that the quote for the rear extension and kitchen opening reached you and that the details make sense. The $41,500 covers the structure, roofing, windows and first-fix electrics and plumbing; kitchen units, flooring and decoration are not included. You asked about the build programme at the site visit, so I'm happy to talk it through on a short call this week. The quote is valid for 60 days, so there's no rush.'
Two things need fixing before it is sent. The 60-day validity is invented, because the details didn't state one; delete the sentence or add the real validity to the quote record so the next draft is right. And 'this week' commits the owner to a day nobody agreed. Both are common, and both are why the rule about anything not in the details exists and why a person reads every draft. Counting how many drafts needed a fix, and of what kind, is the cheapest measure of whether the build is working.
Site rules to write into the scope before anyone builds
A building firm has risks a general AI policy won't name. This is a filled-in starting point; the consultant adapts it in phase 2 and the owner signs it before anything is built.
RULES FOR THE FIRST PROJECT
1. AI drafts, a named person approves. Nothing reaches a client or a
subcontractor unread.
2. AI never approves variations, payments or programme changes.
3. Method statements, risk assessments and structural points stay with the
competent person who signs them. AI may tidy that person's own wording
and nothing else.
4. Photos uploaded for any workflow show no faces, number plates or
neighbouring properties. Crop or retake.
5. Client contracts and subcontractor personal details go only into the
business-plan tool named in the policy, never a free or personal account.
6. Every draft shows its source: the quote record or log line it came from.Rule 3 matters most. A method statement or a risk assessment carries a signature, and the signer owns the substance. On rule 4, OpenAI's image upload FAQ says images are resized before analysis and that file names and metadata aren't read, so the date and the address have to be in the note itself; a photo's own timestamp won't carry through to the log. Rule 5 is about plan type. Consumer ChatGPT and Claude plans let a user switch off use of their chats for model training in privacy settings, while business plans such as ChatGPT Business and Claude Team don't train on business content by default. A foreman pasting a subcontractor's insurance details into a personal account has made a decision the firm never agreed to.
Seven questions that suit a building firm
The general list of consultant questions lives in what a small builder should ask an AI consultant for. These seven are the ones where a building firm's answer differs from an office firm's.
| Question | Why it matters on a building firm | Worrying answer |
|---|---|---|
| Can the workflow be used from a phone with patchy signal? | Foremen record notes in a van or a cabin, often offline; a workflow built for a desktop breaks on day one | 'They can do it back at the office' |
| What happens to site photos that show people or neighbouring property? | Photos carry faces, number plates and other people's homes, and some tools keep uploads | Photos go to a free tool 'just for testing' |
| Which decisions will AI never make? | Variations, payment approvals, method statements and structural points need a named person | 'Fully automated, start to finish' |
| Will you test it on our own quotes and logs? | Your shorthand, supplier names and job names break demo data | Tests only on a sample project |
| What do you need from our subcontractors? | Insurance details and contacts are personal or commercial data | A request for the whole subcontractor list on day one |
| What is the plan if the foremen don't use it? | Adoption decides whether time is saved; one keen foreman is a better pilot than all four | No mention of adoption, or 'training will fix it' |
| Who owns the instructions, and where do they live? | You must be able to edit them when a form or a tool changes | Stored in the consultant's own account |
Costs the proposal doesn't list
One vendor page says hidden costs consistently add 40 to 60% to stated budgets, citing data preparation, integration, change management and annual maintenance. That is a vendor's claim about programmes for larger firms, not a survey. In the worked example, crew time and seats add $1,150 to a $7,500 fee, about 15%. The lines are right in kind, though, so budget for each at a small firm's scale.
- Tidying the data. If quotes are filed as a mix of PDFs, spreadsheets and emails, allow six office hours to get them into one log: $240 at $40 an hour.
- Foremen's time. If the project touches the site, as daily logs and photo workflows do, allow seven hours across four foremen for interviews, testing and the handover: about $315 at $45 an hour. It is cheap beside the consultant, but it has to be scheduled around site work.
- Re-testing when something changes. Allow half a day a year, $375 at $750 a day and $1,000 at $2,000. Tools change behaviour and features retire. Microsoft retired Lens, removed it from app stores on 9 February 2026 and disabled scanning after 9 March 2026; a team that scanned delivery notes with it had to move to the scan feature in the OneDrive mobile app or Google Drive's scanner.
- Support after the handover. A booked review day each quarter is cheaper than a monthly retainer for a firm with one workflow. A reference point: Contra's page for automation freelancers puts retainers at $1,000 to $5,000 a month.
When a consultant is the wrong first buy
Three situations call for a smaller purchase, or none.
If your current construction software has the feature, ask its vendor first, because setup help may be included and the data is already there. If you can name the job and the rules yourself, buy phase 1 alone or a three-hour advice session, which costs about $195 to $600 at goLance's mid-level to senior hourly bands, and build the rest in-house. And if the quotes, logs or invoices are not in one place yet, the first project is a filing job, not an AI job; tidy first and the later build costs less.
For a firm that would rather rank the jobs with someone, that is what my AI implementation consultation covers: finding the jobs where AI pays off, automating them or adding AI to the tools the team already uses, and handing over something the firm can run. The contact page has the form.
Questions builders ask about the cost of a first AI project
Can a five-person building firm afford a first AI project?
Usually yes, in the small shape. Phase 1 alone, one audit day, costs $750 to $2,000 at the rates used here, and a three-hour advice session costs about $195 to $600 at goLance's mid-level to senior hourly bands. A full six-day project at $750 to $1,250 a day is $4,500 to $7,500, so a firm that small should test the payback sum before committing.
Does the consultant need to be a construction specialist?
It helps with site vocabulary, trade shorthand and paperwork, but it can cost more: the construction-focused page checked for this tutorial quotes $150 to $350 an hour, against goLance's $65 to $200 for mid-level to senior AI consultants generally. Either way, insist on a test with your own quotes or logs, and ask what they have built for a firm your size.
What if the foremen won't use it?
Plan for that from the start. Pilot with the one foreman most likely to try it, keep the step on the phone to a minute or two, and let the office do the review so site staff never see an extra form. Count real usage at the 30-day check, and if it is low, change the workflow before paying for more sessions.
Do we need new software for a first project?
Usually not. Most first projects run on the quote log or job system you already have plus an assistant on a business plan. ChatGPT Business and Claude Team both list Standard seats at $20 a user a month on annual billing ($25 monthly) with a two-seat minimum, so two seats are $480 a year. Check whether your current construction software already includes the feature.
Is a readiness assessment worth it for a small contractor?
Rarely. One construction advisory page prices assessments for firms of 20 to 200 staff at $15,000 to $30,000 over three to six weeks, covering a workflow review, a data audit and a roadmap. A fourteen-person firm usually needs a ranked answer to one question: which job to build first. Phase 1 gives that for one consultant day, and you can stop there.
