Construction Operating System

An operating system for builders at every scale.

General contractors, developers, trades, and home renovators run on coordination — between the field and the office, between subs and GCs, between drawings and reality, between the homeowner and the crew. The system underneath the business is where the margin lives. We engineer it for whatever scale you operate at.

01 Job intake · Reduce ramp time

From service call to project bid — captured, qualified, and dispatched.

Construction operators handle inbound work at every scale. A homeowner calls with a leaking pipe. A developer sends an ITB for a $4M build. A property manager texts about an HVAC unit failing. Today most operators handle these in different inboxes, with different processes, losing the small jobs to slow response and the large jobs to no qualification. We build the intake system that handles every scale — service calls dispatched in minutes, project bids qualified before estimators waste hours.

Multi-channel intake: Phone calls, web forms, emails, texts, ITBs, procurement platforms — all funnel into one inbox with type tagged.
Service call dispatch: Urgent service work routed to available crews in the right region, with the right gear, in seconds.
Bid qualification: Larger project invitations get scored against your bid criteria — project size, trade fit, margin profile, current backlog — before they hit an estimator's desk.

02 Bid qualification · Reduce no-bid rework

Project bids qualified before estimators waste hours.

GCs and subs receive bid invitations constantly. Most aren't a fit — wrong project size, wrong scope, wrong region, wrong margin profile. Estimators waste days reviewing bid packages that should have been declined on day one. We build the bid qualification agent that reads incoming invitations, scores them against your bid criteria, and surfaces only the ones worth estimating.

Invitation parsing: Bid invitations from email, ITBs, and procurement platforms get parsed for scope, value, timeline, and location.
Scoring against criteria: Project size, trade fit, margin profile, geographic radius, current backlog — scored against your rules.
Decline drafting: For bids you won't pursue, the system drafts a polite decline. Relationships preserved, no manual work.

03 RFI management · Reduce response time

RFIs that don't live in email threads.

RFIs are the single largest source of project delay. Industry data shows average RFI response times of six to ten days, with delays cascading into schedule slippage and rework. Most RFIs live in scattered email threads and Excel logs that don't sync with the architect's records. We build the RFI system that captures, routes, tracks, and ages every RFI — and ties each one to drawings, costs, and schedule impact.

Capture and routing: RFIs created in the field route to the right reviewer with the relevant drawing references attached.
Aging and SLA: Every RFI tracked against its SLA. Overdue items escalate automatically. RFI aging reports surface schedule risk early.
Drawing and cost linkage: Each RFI ties to specific drawing sheets and cost codes. When the response changes scope, the change flows into change orders without re-keying.

04 Change orders · Reduce margin leakage

Change orders that don't sit in approval limbo.

Change orders are where projects bleed margin — whether it's a $4M GC project or an $80k kitchen remodel. RFIs that change scope often don't flow into change orders for weeks. CORs sit awaiting signatures. By the time the CO is approved, the work is half-done at the original price. We engineer the change order lifecycle — from trigger to draft to signature to invoicing — with full traceability and signature workflows that don't lose days to paper-pushing.

Auto-drafting from triggers: When an RFI response changes scope, when a homeowner approves an upgrade, when a sub flags a deviation — the system drafts the change order with cost impact pre-calculated.
Approval workflows: Change orders route through the right approvers — GC, owner, homeowner, lender — with e-signature. Approval status visible to everyone, in real time.
Margin impact tracking: Each change order tagged with margin impact. Approved COs flow into invoicing without manual entry.

05 Field sync · Reduce paper trails

Daily logs, service reports, and field updates — without the manual assembly.

Field activity lives in WhatsApp threads, paper logs, emails, photos on someone's phone, and notes in three different apps. At month-end, someone spends days assembling the field report for the owner — or the homeowner. For service trades, completed job reports take an hour each to write up. We build the field-to-office sync layer that captures field data once, structures it, and assembles owner-ready or client-ready reports automatically.

Mobile-first field capture: Daily logs, photos, service notes, and safety reports captured on-site, tied to project or service call.
Auto-assembled reports: Owner pay-app backup packages, monthly field reports, homeowner project updates, completed-service summaries — assembled from live data.
Searchable history: Every photo, log entry, and field note searchable across projects and dates. No digging through shared drives.

06 Under the hood · Run the operation

The view that shows you every project, every service call, every margin, at any moment.

Most construction operators don't have a real-time view of their operation. The GC has a PM who insists the project is on track. The trade owner doesn't know if today's service calls are profitable. The renovator can't tell whether the kitchen reno is leaking margin. We build the dashboard that aggregates schedule status, budget variance, RFI aging, change order exposure, service call profitability, and crew utilization into a single view that updates as the work happens.

Schedule and budget: % complete vs. planned, actual vs. budget per cost code. Slippage flagged before it cascades.
Service profitability: Margin per service call, per tech, per call type. Find the work that pays and the work that doesn't.
Risk surfacing: Open RFIs over SLA, change orders awaiting approval, service calls aging in invoicing — rolled up by project or service line, ranked by exposure.

What we build on

Engineered on the tools that already work. Custom code where they can't reach.

We don't reinvent infrastructure that already exists. HubSpot for CRM where it fits the operation. Zapier, Make, and n8n for workflow automation where the platforms reach. Custom code, vector databases, and bespoke agents where they don't. The engineering decision is matching the right tool to the right layer of your stack — not selling you a custom build for a problem a $20/month tool already solves.

HubSpot · Zapier · Make · n8n · Custom agents · Vector databases · OCR pipelines · RAG retrieval

This is what we build for construction operators.

Every system above is engineered against your specific work — whether you run a multi-project GC operation, a 12-truck HVAC business, or a high-end renovation firm. We sit inside the operation long enough to understand how the work actually moves between the field and the office, then build the system that fits. Most engagements run three to four months. We turn down work that doesn't fit the model.
