The role descriptions on this page reflect current construction industry practice as of September 2026 and are due for review by September 2027.
A construction office manager job description for a 5 to 15-person high-ticket service business should list 14 specific operational tasks — not a generic HR template copied from a staffing site. The 14 tasks that consistently produce output in small construction operations cover lead routing, proposal management, subcontractor coordination, milestone tracking, AR follow-up, permit management, client communication, payroll inputs, vendor records, job documentation, review requests, materials coordination, field crew support, and owner administrative backup. Six additional tasks that commonly appear on generic job descriptions — lead follow-up sequences, quote reminders, invoice reminders, review requests, milestone alerts, and field documentation collection — are mechanical enough that they can run consistently without a dedicated person in the role handling them each time.
Most construction office manager job descriptions are copy-pasted from staffing site templates designed for 100-person corporate offices. They list tasks like “maintain filing systems,” “coordinate executive calendars,” and “assist with special projects” — language that describes a support role in a Fortune 500 building, not someone who needs to handle a permit application, chase a subcontractor, and field a client call about a punch list item in the same morning.
The cost of a misaligned job description is not the time spent writing it. It is the 60 to 90 days of onboarding a person into the wrong role before the owner realizes the hire is managing the wrong 40 hours.
According to the Bureau of Labor Statistics, office and administrative support occupations turn over at a rate that costs businesses 50 to 75% of annual salary per replacement. In a construction business running $1M to $3M in revenue, one mis-scoped hire and a subsequent replacement adds $30,000 to $45,000 in direct and indirect cost before the right person is in the seat doing the right work.
The job description is where that mistake either starts or gets prevented.
These are the tasks that appear consistently across well-run 5 to 15-person construction operations — the ones that directly connect to revenue, project delivery, or client relationship quality.
| # | Task | What It Requires |
|---|---|---|
| 1 | Route inbound calls and leads to the right person | Real-time responsiveness, business context |
| 2 | First response to lead inquiries within business hours | Speed + authority to represent the business |
| 3 | Send proposals and track unsigned quotes | Process ownership, follow-through |
| 4 | Coordinate subcontractor scheduling across active projects | Relationship management, calendar judgment |
| 5 | Manage permit applications and inspection scheduling | Local knowledge, regulatory familiarity |
| 6 | Track project milestones and flag delays to the owner | Active monitoring, judgment on what matters |
| 7 | Handle client communication during active projects | Tone, context, relationship continuity |
| 8 | Process AR and follow up on outstanding invoices | Persistence, financial awareness |
| 9 | Maintain vendor and subcontractor contact records | Consistency, accuracy |
| 10 | Process payroll inputs for field crew | Accuracy, confidentiality |
| 11 | Organize job documentation (contracts, change orders, photos) | Discipline, file system ownership |
| 12 | Coordinate material orders and track delivery schedules | Vendor communication, project timing |
| 13 | Support owner with scheduling and calendar coordination | Proximity to owner decisions |
| 14 | Onboard new subcontractors and maintain compliance records | Detail orientation, process ownership |
These 14 tasks require human judgment — the ability to read a situation, adapt, and make a call that an owner would make if they were standing there. They are the tasks that justify the $78,000 in loaded employment cost a construction office manager role carries. See the full cost breakdown for this role.
Six tasks commonly appear on construction office manager job descriptions that are mechanical enough — identical execution every time, no judgment required — to run consistently without a person initiating them manually.
1. Lead follow-up sequences. A first response to an inbound lead inquiry within five minutes during business hours, followed by a three-touch sequence over seven days. The trigger is the lead submission. The content is templated. The timing is fixed. This does not require a person to remember it happened and decide to act — it requires a consistent system that runs even if the admin is on the phone with a subcontractor, out sick, or managing four other things.
2. Quote follow-up reminders. A check-in at day three, day seven, and day fourteen after a proposal is sent. The sequence is the same for every unsigned quote. A human is needed to send the original proposal. A human is not needed to initiate each follow-up on schedule.
3. Invoice payment reminders. Outreach at 30 days, 45 days, and 60 days after an invoice is issued. The language is templated. The trigger is the invoice date. Consistent execution here shortens average days-to-cash by 15 to 22 days in most service businesses — not because someone worked harder, but because the reminder went out on schedule instead of whenever the admin got to it.
4. Review requests at project close. A message to the client within 48 hours of final payment received, with a direct link to the review platform. Every closed job. Without exception. The trigger is payment confirmation.
5. Milestone update notifications to clients. A brief progress note when a project hits a defined stage — demo complete, rough-in done, punch list open. Clients report higher satisfaction and generate more referrals when they receive consistent project communication, even brief. This does not require a person to draft a fresh message for each update — it requires defined stages and a template for each one.
6. Field documentation collection. A daily or weekly request to field crew for job photos, progress notes, and any observed issues. The message is the same every time. The schedule is fixed. The admin's job is to review what comes in — not to remember to send the request.
These six tasks, when they run consistently, eliminate the most common source of lead loss, late payment, and client dissatisfaction in small construction businesses. They run even if the admin is on a call, overwhelmed with a permit issue, or managing a subcontractor dispute — because they do not depend on the admin's available bandwidth that day.
A construction office manager job description written for a $600,000 business is not the same document a $2M business needs. The tasks shift as the operation scales.
At $600K to $900K, the role is wide and shallow — one person handling everything administrative, learning the business, building the vendor relationships. The 14 tasks above describe this role fully.
At $900K to $1.5M, the bottleneck shifts. The admin is not the problem — the workflow is. At this volume, the mechanical tasks (follow-up sequences, reminders, documentation requests) are consuming 8 to 12 hours per week that the admin could be spending on higher-judgment work: subcontractor relationships, permit complexity, client communication on active projects. Businesses that hit this ceiling and try to solve it by hiring a second admin are spending $78,000 to solve a workflow problem. Businesses that solve the workflow problem first and keep the headcount flat are the ones that hit $2M without a corresponding payroll spike.
The job description is not just a hiring document. It is a description of where human judgment is required in the operation — and implicitly, a map of where the ceiling is.
TIM is Digital Labor — a business operating system for US service businesses with 1 to 15 employees running high-ticket projects. TIM handles lead follow-ups, professional quotes, project tracking, payment requests, and client communication — the work that keeps businesses from growing. TIM is priced against the $4,000/month salary of the employee it replaces, not against $20/month software.
The most useful version of a construction office manager job description is not the one you post on Indeed. It is the one you write before you post — the version that forces you to name exactly what output you are buying at $78,000 per year, which tasks require a person, and which ones are currently falling through the cracks not because nobody is doing them, but because they require consistency the business has not yet built.
