Every job site, every angle, every hour.
From sunrise walkthroughs to midnight pours — our estimators build their takeoffs around how work actually happens on your site.

We're not just typing numbers into software. Our estimators have run jobs, swung hammers, and read enough drawings to spot the things that turn into change orders later.
01
Fast Turnaround
Most takeoffs come back in 3–7 days. Need it tomorrow? We have rush options for tight bid deadlines.
02
Accuracy First
Detailed digital takeoffs land within ±5% of actuals. Every assumption is logged so nothing surprises you.
03
Competitive Pricing
Flat-fee or per-sheet pricing — no hidden charges. You always know what an estimate costs before we start.
04
Senior Estimators
Estimates produced by people with field experience — not interns. Each is reviewed by a senior before delivery.
05
CSI Division-Wise
Every estimate is organized by CSI MasterFormat so you can drop sections straight into your SOV or sub bids.
06
Always Available
Direct line to the estimator on your job. No tickets, no queues — just a quick call when you need answers.

What Clients Say
Estimates that win work — and earn return clients
"Tight schedule on a school renovation. Sent plans Friday afternoon, had a full division-7 takeoff in my inbox Monday. Won the bid by 4%."
"Their MEP estimates are the best I've seen. They catch the low-voltage and fire-alarm scope that other estimators miss every time."
"The bid package they assembled was cleaner than anything our own team has put together. Ownership approved it without a single follow-up question."
"We hand them the ugliest hand-marked plan sets and they still come back with a takeoff we'd stake our bid on. Fast turnaround, no drama."
"Their sitework and earthwork numbers caught a grading conflict our civil engineer had missed. That single catch paid for the estimate three times over."
"We've used three estimating firms over the years and West is the only one we kept. The estimates come back clean, on time, and with assumptions documented so we know exactly what's in and out."

Common Questions
Everything you might want to know — answered.
Still curious about something? Send a quick note. A real estimator (not a chatbot) will get back to you within one business day.
Ask a questionOn most projects our estimates land within ±5% of final construction cost. Highly conceptual projects (where plans are partial or schematic) sit closer to ±10%. We log every assumption so any variance is traceable — no black-box numbers.
Single-trade takeoffs usually come back in 3–5 business days. Full GC estimates take 7–10 business days. We offer 48-hour rush turnaround for tight bid deadlines at a small premium — just ask when you send the plans.
PDFs, DWGs, Revit exports, hard-copy blueprints, even rough hand sketches. If we need clarification we ask before starting work — never after. You can send files via email, Dropbox, Google Drive, or a project management tool you already use.
Most jobs are flat-fee, quoted in advance based on scope and complexity. Some clients prefer per-sheet or hourly pricing for ongoing work — we can structure either way. There are no hidden charges and the price you see is the price you pay.
Yes, standard practice. We sign your NDA before any plans change hands. If you do not have one, we will provide ours. All project files are stored encrypted and never shared with third parties.
Yes — value engineering is included in our cost-estimation deliverable. We flag where alternate materials or assemblies could save money without changing the design intent, and quantify the savings for each option.
Our core deliverable is pre-construction estimating, but several long-term clients keep us on retainer for change-order pricing, cost forecasting, and budget tracking through the build. Ask about our cost-management packages.
PlanSwift, Bluebeam Revu, Trimble Accubid, and STACK are our day-to-day tools. We deliver in formats that fit your workflow — Excel, PDF, and marked-up plan files.
