Work packages: what moves to the assistant and what stays with your team

A construction virtual assistant is a dedicated remote administrator and project coordinator for the office side of building: the logs, documents, follow-ups and paperwork that sit between the site, the design team, subcontractors, suppliers, the owner and your accounts. You buy a seat, measured in hours, inside your own project platform, email and file storage. On most contractors' teams this work lands today on the project manager, the superintendent or the owner, usually after a day on site.

Buy it by work package, not as "admin help". A package names the inputs, the output and the person who signs off, so the assistant knows where to stop. The table is the full list; most buyers start with three or four packages and add the rest after the first month.

Decision rights: prepare, route, decide

Construction paperwork carries signatures, dates and money, so the risk in this role sits at the handoff between preparing a document and deciding on it. Put this matrix in the onboarding pack. The assistant owns the first two columns; the third column never moves.

One example of where the line sits: on federal and federally assisted contracts covered by the Davis-Bacon and Related Acts, contractors and subcontractors submit weekly certified payrolls with a signed Statement of Compliance (US Department of Labor). The assistant can collect timesheets and assemble the payroll report; the signature stays with the person accountable for it.

This file is a buying guide, not legal, insurance or safety advice. Lien, licensing, permit and contract rules differ by state and by country; your attorney decides.

A statement of work you can copy

Fill in the brackets and attach the result to the request and to the agreement. Each clause answers a question that otherwise comes up in week two.

Engagement models compared

Most firms that buy a seat keep the field-facing work local and move the screen work: the registers, logs, follow-ups and packages. For the wider choice between a dedicated person and a managed team, see dedicated team vs staff augmentation.

Total cost of ownership: in-house hire vs construction VA

Sources: US Bureau of Labor Statistics, Occupational Outlook Handbook, May 2025 median: secretaries and administrative assistants $48,310 a year ($23.23 an hour), checked on bls.gov 13 November 2026. Employer FICA rate from the IRS; BLS Employer Costs for Employee Compensation for the benefits share. VA rate = our recruiting partner's published construction admin rate, billed monthly in arrears for hours worked.

A part-time seat (80 hours a month) costs $520–$800 a month, or $6,240–$9,600 a year. The useful comparison for many contractors isn't against a new hire at all: it is against the hours a project manager or owner spends on logs and chasing today. Those hours are billed to your projects at a PM's cost, and every one moved to a seat at $6.50–$10 goes back to the field, to the client or to winning the next job.

Some buyers need more than admin. Estimating and quantity takeoff support, or drafting support such as shop drawings, sits at $8–$14 an hour through the same partner, as a separate seat or a separate line on the same request. The estimator still owns the number.

Sizing the seat from a workload tally

Don't guess the hours. For one normal week, have the PM and the office note every item from the work packages above and the minutes each takes, then multiply out to a month. The example below shows the arithmetic for a contractor with four active commercial jobs; the inputs are illustrations, not benchmarks.

As a starting point: a residential builder or specialty trade with a handful of jobs often begins at 80 hours a month on permits, scheduling, supplier follow-up and invoicing; a general contractor with several commercial jobs at once usually fills a full-time seat.

Controls for documents, money and signatures

The assistant will see drawings, contracts, subcontractor insurance and bank details on invoices. Agree these controls before access starts.

Write an approval matrix for money: who may approve a purchase order, a change order, a sub payment and a pay application, and up to what amount. The assistant prepares and logs; the named person approves. Keep a simple rule for bid security too: bid tabulations and proposals go only to the people the estimator names.

Service levels and KPIs to put in writing

Measure for 30 days, then set targets from your own numbers. Each measure has a data source you already have, so nobody builds a report just to prove the seat works.

Avoid one target that sounds good and works badly: "RFI response time". The assistant controls how fast an RFI is logged and chased, not how fast the architect answers. Measure the follow-up, and report the design team's response times to the PM as information.

Vendor questionnaire: fourteen questions

People

1. Does the assistant work only for my company?
2. What construction, engineering or project-admin experience will candidates have, and in which platforms?
3. Are candidates tested on construction tasks (an RFI log, a submittal register, a messy project folder, a follow-up to a late sub) before I meet them?
4. Do I interview and choose?

Price and terms

5. What is the hourly rate for this role, and what moves it up the range?
6. Is estimating, takeoff or drafting support priced separately?
7. Are there recruitment or setup fees? Is there an advance payment, and is it refundable?
8. What is the trial period, the notice period and the replacement policy?

Data and authority

9. Will the assistant work only in my systems, under a named login?
10. What does the provider put in writing about confidentiality of drawings, bids and client data?
11. Does the provider confirm in writing that the assistant signs nothing and approves nothing?

Continuity

12. What is the backup for internet and power outages during my working hours?
13. How is cover arranged during the assistant's leave and public holidays, especially around a pay application date?
14. If the assistant leaves, how fast is a replacement shortlisted, and who trains them?

Our outsourcing contract checklist covers the clauses behind these answers.

Scope by firm type

The same title covers very different seats. Place your firm in one of these boxes before you request candidates: it decides the platforms the assistant must know and which packages come first.

Firms outside the US (UK, Canada, Australia) buy the same seat with their own documents and forms: the assistant works to your market's contracts, payment rules and formats, and the compliance decisions stay with your qualified people.

Software the seat works in

Candidates can be matched to the platforms you run. Name them in the request; the provider can put a task in your own platform or a sandbox into the test.

Product names show tools candidates can be matched to, not endorsements.

Acceptance test before you choose

General admin skills don't carry over to construction without the context. Someone who schedules well but has never seen a submittal register needs months to catch up. Ask for a short work sample from each shortlisted candidate, built on your own documents with names removed:

• RFI: log a field question from a superintendent's email, attach the right sheet, set a due date and write the transmittal to the architect.
• Submittal register: build ten rows from two spec sections and flag which items need shop drawings and which need product data.
• Document control: sort a messy folder of drawings, revisions, change orders and emails into your structure, with superseded sheets marked.
• Follow-up: write a firm, polite chase to a sub whose submittal is a week late, and a status reply to a client who asks when the kitchen goes in.
• Accuracy: check a sub's pay application against a schedule of values and list the differences, without correcting the numbers.
• The line: one item that needs a decision (a sub asks to swap a specified product); the right answer is to route it, not to answer it.

Score each task on accuracy, completeness and tone, and ask the candidate to explain one choice live on a call.

Onboarding plan: 30, 60, 90 days

1. Week 1, access and one project: named logins with the agreed permissions; the decision-rights matrix, file naming rule and confidentiality agreement read and signed; a walk-through of one live project; the assistant takes over that project's RFI and submittal logs with a daily check-in.
2. Weeks 2–4, the daily loop: end-of-day note running; document control on the first project; COI and lien waiver tracker built for every active sub; the PM reviews each outgoing message for the first two weeks, then samples.
3. Day 30 review: baseline numbers for the service levels; the seat size checked against the workload tally; decide which project and package comes next.
4. Days 31–60, more projects and money paperwork: remaining active projects added; permit tracker and inspection booking; purchase orders and delivery follow-up; the first pay application package prepared for the PM.
5. Days 61–90, full scope: owner reports and portal updates, bid administration if in scope, close-out packages on finishing jobs; targets written into the agreement from the baseline.

Risk register

Exit and handover

All work stays in your platform, your file storage and your email, so nothing has to be handed back. At the end of an engagement, ask for a final handover note (open RFIs and submittals, permits near expiry, waivers outstanding, pay application status), remove access the same day, and change any shared mailbox passwords.

Requesting candidates

Requests sent through this site go to our recruiting partner, a managed VA agency:

1. Send the scope: firm type, active projects, platform, the work packages and hours, using the statement of work above if it helps.
2. Review the shortlist: candidates with construction, engineering or project-admin experience, screened and tested, usually in about 2 business days.
3. Interview and choose: nothing is paid before you choose; billing is monthly in arrears for hours worked; an assistant who isn't a fit is replaced at no extra cost.

The trade-offs: an agency costs more per hour than a freelancer you recruit yourself, in exchange for screening and replacement; the first month needs your PM's review time; after the 30-day trial a notice period applies. Back-office finance work such as job costing can also go to an outsourcing firm; the accounting outsourcing drawer lists providers scored on published prices and terms.
