EstimaBuild provides independent construction cost estimates, quantity takeoffs, and scope reviews for owners, architects, and contractors — with clear assumptions, exclusions, and backup you can defend.
A number without a basis is just a guess. We produce estimates with documented assumptions, defined contingencies, and clear scope boundaries — so when someone pushes back, you have the backup to defend it.
AACE-standard estimates from ROM through Class 2 — with CSI breakdowns, contingency analysis, escalation, and a written basis of estimate. Every number has a source; every assumption is stated.
Learn more →Independent material and labor takeoffs referenced to drawing sheets, with exclusions and clarifications clearly noted. Used for bid prep, sub verification, change order support, and procurement.
Learn more →We identify where AI-supported tools can speed up document review, benchmarking, and scope-gap checks — without removing estimator judgment from the process.
Learn more →On data center and mission-critical projects, MEP, low-voltage, power, controls, and security scopes can drive a major share of fit-out cost. Getting these assumptions wrong at budget stage — underestimating LV scope, missing trade boundaries, or applying standard commercial $/sqft without adjusting for density — can create large gaps that don't surface until construction.
We have estimating experience on data center and mission critical projects, with specific expertise in low voltage cost estimating. We understand the scope boundaries between trades, the current pricing environment for LV work, and where budget assumptions typically fall short.
LV & MEP Scope Coverage
Need a number quickly for a feasibility decision or early budget discussion? This is our streamlined path to an indicative ROM range — useful for go/no-go decisions, not for bid submission or project commitment. For detailed estimates, quantity takeoffs, or validated cost plans, contact us directly.
Share your project scope, building type, size, and phase. Drawings optional at ROM stage.
We review the brief, apply relevant benchmarks, and identify the key assumptions driving the range.
An estimator reviews the output, sanity-checks the range, and flags anything that could move the number significantly.
A cost range with stated assumptions and key exclusions — suitable for early budget conversations only.
Independent cost estimating serves a different purpose for each party. We tailor our deliverables to what you actually need — not a one-size-fits-all report.
An owner's estimate is your most important tool before a project goes to bid. It tells you whether the bids you receive are competitive, where you're being overcharged, and whether your budget needs to change before you commit.
Cost surprises at bid time reflect on your design. We give your team an independent cost check at each design phase — so you're not the last to know the project is over budget.
A second opinion on pricing, an independent check on sub quotes, or a vendor-neutral view on which AI tools are worth adopting — we work alongside GC estimating teams without competing with them.
Getting the cost right from the start isn't just about the number — it's about understanding what's in it, what's not, and what could go wrong. That takes an estimator.
Too low and the budget blows up. Too high and you lose the bid or the approval. Contingency is a judgment call — based on design maturity, site risk, and procurement conditions — not a blanket percentage.
Missing a trade, overlooking a system, or assuming work is in a sub's scope when it isn't — these are the errors that turn a winning bid into a money-losing job.
Every estimate rests on assumptions. We write them down — site conditions, procurement lead times, labor availability, design intent — so when conditions change, you know exactly what to revisit.
All estimates follow AACE International classification methodology — with defined accuracy ranges, escalation, and a written basis of estimate that owners, lenders, and subs can audit.
"We needed an independent check on our quantities and a credible second opinion on pricing before the project went to IFB. EstimaBuild delivered a thorough line-item review that held up through the bid process. Their VE recommendations gave the team real options — not just percentage cuts — and the final costs tracked closely with what they projected."
Structured, defensible deliverables — not PDFs with vague ranges. Every output includes assumptions, exclusions, and a clear basis of estimate.
AACE Class 2–3 estimate with CSI division breakdown, quantity basis, unit rates, and contingency analysis.

There are dozens of AI estimating tools on the market. Most GCs don't have time to evaluate them properly — and vendors aren't going to tell you where the gaps are. We will.
We review your current workflow, identify where AI can save time, then recommend only the tools that fit — based on your project types, team size, and budget. No upsells. No referral fees.
Common Use Cases
Speed up quantity extraction from drawing sets — validated by your estimator before any number leaves the office.
Structure sub quotes side-by-side and flag scope gaps before you sign a contract.
Compare estimates against market data and past projects to catch outliers before they become surprises.
Estimating outputs in a format your PMs, owners, and subs can actually read and act on.
We've delivered estimates, takeoffs, and workflow advisory across commercial, institutional, industrial, and infrastructure projects.
We needed an independent check on our quantities and a credible second opinion on pricing before the project went to IFB. EstimaBuild delivered a thorough line-item review that held up through the bid process. Their VE recommendations gave the team real options — not just percentage cuts — and the final costs tracked closely with what they projected.
EstimaBuild supported our estimating team on a federal facilities project where accuracy and documentation were non-negotiable. Their cost estimates were detailed, defensible, and stood up to owner review without revision. Beyond the numbers, their AI tool advisory saved us from committing to a platform that looked impressive in the demo but didn't fit our actual workflow — real savings before we spent a dollar on the wrong software.
We brought EstimaBuild in during schematic design for a mixed-use project in Austin. Their ROM came in within 15% of where we landed at SD — which is exactly the kind of early-stage discipline that keeps a project on track. By the time we hit Construction Documents, their estimate was within 4% of the CD estimate. The VE guidance they provided along the way was incorporated into the design before drawings were issued, saving the client real money before a shovel hit the ground.

We're an independent construction cost estimating and AI workflow advisory firm. We help general contractors, developers, owners, and designers with cost estimates, quantity takeoffs, AI tool selection, and workflow implementation — from early preconstruction through project execution.
An estimate is an owner-side planning tool that establishes expected project costs — used to set budgets, secure financing, and evaluate feasibility. A bid is a contractor-side pricing document submitted to win work. EstimaBuild produces independent estimates, not bids.
A ROM is a high-level cost projection used before a project commits to full design or preconstruction. It establishes a defensible budget range that allows owners, GCs, and lenders to make Go/No-Go decisions without a lengthy engagement.
No. We work on a project-by-project basis. You can start with a single cost estimate, a one-time workflow assessment, or a defined advisory scope — and expand only if it makes sense. No retainer, no minimum commitment.
AI can help if your team spends significant time on repetitive tasks like takeoffs, bid comparisons, or reporting. We offer a free workflow assessment to identify where AI would have the most impact — without requiring any software investment upfront.

AACE-standard estimates and independent quantity takeoffs — from early feasibility through bid-ready documentation. Every output is reviewed by a certified estimator.
AACE International defines five estimate classes by design maturity and expected accuracy. We deliver Class 5 through Class 2, depending on the information available and what you need it for.
Enter your project parameters to get a preliminary cost range. This is a planning tool — not a substitute for a formal estimate. Book a consultation to get a documented ROM with assumptions and contingency basis.
Indicative cost range only · AACE Class 5 equivalent · For planning purposes
We don't send you a spreadsheet and call it done. Every estimate comes with the documentation that makes it defensible.
Every engagement includes a documented basis of estimate — what drawings and documents we used, what we assumed, what we excluded, and what would change the number if conditions differ.
Contingency is set based on design maturity, site risk, and market conditions — not a flat percentage. We document the reasoning so stakeholders understand what the buffer covers and why.
We work directly with trade subcontractors to verify pricing for key scopes — giving our estimates real market grounding beyond published cost databases.
All detailed estimates are structured by CSI MasterFormat division so the numbers are traceable, comparable across projects, and easy to hand off to your project controls team.
Where scope or budget tension exists, we identify VE opportunities with estimated cost impact — so the design team has real data to work with, not gut instinct.
We note current market conditions, material availability concerns, and any escalation factors we've applied — so the estimate is transparent about what could move the number.
Beyond general commercial and institutional work, we have hands-on estimating depth in sectors that require specific knowledge of systems, pricing dynamics, and scope risk.
Cost estimating for data center construction and fit-out, with specific expertise in low voltage (LV) systems — structured cabling, power distribution, UPS, PDU, BMS, and security infrastructure. We understand how MEP-heavy, high-density environments price out differently from standard commercial construction, and where scope gaps between trades are most costly.
Heavy civil, process facilities, and large-scale infrastructure projects where unit cost databases alone are insufficient and direct sub pricing relationships are essential.
Government facilities, federal programs, and institutional projects where AACE methodology, documentation rigor, and defensible contingency analysis are non-negotiable.
Data center and mission-critical construction cost estimating requires a fundamentally different approach than standard commercial work. MEP, low voltage, power, controls, and security scopes can drive a major share of total fit-out cost depending on project type, density, and tier requirements — and the scope boundaries between trades are where budget assumptions most commonly fail.
EstimaBuild has estimating experience on data center and mission critical projects, with specific expertise in low voltage systems cost estimating — including structured cabling, BMS, access control, CCTV, PDU, and UPS infrastructure. We understand current market pricing for LV scopes and the scope gaps between trades that most estimators miss.

We help general contractors and construction firms identify where AI saves real time, evaluate which tools actually fit their workflow, and build custom AI processes trained around how they estimate — not a generic template.
Not a one-time recommendation deck. We map your process, select the right tools, and implement — leaving you with a workflow your team owns and can run independently.
We document your current estimating, procurement, and reporting process from end to end — identifying where time is lost, where errors creep in, and where handoffs break down. Most GCs find 2–3 high-value AI insertion points in the first session. Output: annotated process map + phased implementation roadmap.
PreconstructionWe evaluate the AI tools on the market against your actual workflow — not a generic checklist. We've seen what works in the field and what sounds better in a demo. We don't take referral fees from any software vendor. Recommendations exist to help your team only.
Vendor-NeutralCost estimates, quantity takeoffs, bid leveling, spec review, and scope gap analysis — we help your team move from raw drawings to a structured, defensible estimate faster using AI-supported review tools, validated at every step by an estimator.
EstimatingRFI management, submittal review, daily reporting, and change order documentation all have AI tools that cut paperwork time significantly. We identify where the friction is and match it to the right solution — without overhauling systems that are working.
Project DeliveryEstimating outputs, bid comparisons, and cost benchmarks formatted for the people who actually use them — owners, PMs, and subs. We build dashboards tailored to your project types and reporting cycles, not generic templates.
ReportingAI-structured side-by-side sub quote comparison with automated scope gap flagging — so you catch the $200K exclusion before you sign the contract, not after. We build the template around your trade packages and project types.
ProcurementGeneric AI tools are trained on generic data. The value comes from training them on your project history, your cost structures, your trade relationships, and your scope assumptions. That's what we build.
We structure your past estimates and project actuals into a format AI tools can reference — so benchmarks and unit costs reflect your actual experience, not a national average that doesn't match your market or project mix.
Cost IntelligenceEvery GC has standard scope language — what's always in, what's always out, what needs a clarification. We encode those assumptions into your AI workflow so they're flagged automatically on every estimate, not caught after the fact.
Scope ManagementDifferent GCs divide work differently. We map your standard trade packages into AI bid leveling tools so subcontractor quotes are automatically structured against your scope template — not a generic CSI format that doesn't match how you actually buy.
ProcurementIf you do mostly healthcare tenant improvement and light industrial, your AI benchmarking tool should know those markets. We build project-type-specific cost libraries from your data so the tool flags outliers that matter to your business.
BenchmarkingWe integrate your preferred sub list and vendor pricing into AI comparison tools — so the system knows which subs are reliable, which need padding, and which markets have thin coverage. That context lives in the workflow, not just in your estimator's head.
Vendor ManagementContingency levels, escalation assumptions, and risk registers calibrated to the project types and regions you actually work in — not generic AACE ranges applied blindly. AI-assisted risk flagging trained on your past problem projects.
Risk & ContingencyA structured engagement that ends with your team owning the process — not dependent on a vendor or a consultant to keep it running.
1–2 weeks. We shadow your estimating process, document every step, and identify exactly where AI creates leverage. No assumptions, no generic frameworks.
2–4 weeks. We select the right tools, configure them around your project types and data, and run a controlled pilot on a live project — low-risk scope, real output.
2–4 weeks. We train your team on the workflow — not just the software buttons — and document the process so it doesn't live in one person's head.
AI opportunities exist across the full project lifecycle. We focus on where the time savings and error reduction are largest — starting with estimating and procurement, extending into field operations where it makes sense.
Preconstruction & Estimating
Project Delivery & Field Operations
These are representative examples of what AI workflow implementation produces — the kind of outputs and time savings that justify the engagement.
A commercial GC was spending 3 days on quantity extraction for mid-size office TI projects. After implementing an AI takeoff workflow calibrated to their drawing standards, the same takeoff runs in under a day — with estimator validation built into the process.
A federal facilities contractor was close to signing a 3-year contract with an AI estimating platform that looked strong in the demo. Our independent evaluation identified two critical gaps for their federal project type — saving them from a costly, hard-to-exit commitment.
An AI-structured bid leveling tool identified a missing exclusion in a mechanical sub quote during the leveling process — a scope gap worth approximately $180K that would have been discovered mid-construction. Caught before the contract was signed.

No software commitment required · Vendor-neutral advice
Three engagements illustrating how EstimaBuild delivers estimates, VE analysis, and GC workflow support — with real process and real outcomes.
An architecture firm in early schematic design had three different massing concepts for a mixed-use civic project. The owner needed to select one — but without cost data, every option felt like a guess. EstimaBuild produced parallel Class 4 cost estimates for each scheme: same assumptions, same exclusions, same format. Each estimate was tied to a specific design decision (structural bay, floor-to-floor height, envelope type) so the team could see exactly what drove the delta.
The deliverable wasn't three separate reports. It was a single dashboard — a side-by-side comparison matrix with total project cost, cost-per-SF, hard cost vs. soft cost split, and a scenario sensitivity ribbon showing how each option responded to scope changes. The A/E presented it directly to the owner's board. Option 2 was selected. It was $4.2M less than Option 1 and $1.1M more than Option 3 — but the board understood exactly why.
A GC's CD-stage estimate came in 14% over the owner's established budget. The reflex response — value engineer everything — risked compromising scope the owner cared about. EstimaBuild ran a structured VE analysis using our VE Optimizer: a line-item review that scores each scope element by cost impact, schedule sensitivity, and design intent risk.
The output is a ranked VE candidate list with estimated savings, risk flags, and a "do not touch" column. The owner used it to facilitate a focused one-hour design review. Seven items were acted on. Budget gap closed by 11.3%. The other 3% was covered by contingency release tied to completed permitting — a separate recommendation from EstimaBuild's schedule analysis.
The sample estimate below includes the VE Optimizer section — you can see the format, the ranking logic, and how savings are attributed per line.
A mid-size GC was chasing more work than their estimating team could keep up with. They were winning roughly 1 in 6 bids — not because of price, but because they couldn't get accurate takeoffs completed fast enough to bid competitively on every opportunity. Estimating bottlenecks meant walking away from viable jobs.
EstimaBuild came in as an extension of their in-house team. We handled quantity takeoffs for concrete, framing, and MEP rough-in on two concurrent bid packages — producing traditional L/M/E breakdowns with productivity factors sourced from RSMeans, calibrated to local labor rates. The GC's PMs reviewed and signed off. Both bids went out on time. One was awarded.
Separately, we helped them evaluate two AI-assisted takeoff tools — assessing accuracy on their specific project types before they committed to a subscription. They kept one, skipped the other, and saved the equivalent of four months of software fees in the first year.
Every engagement starts with a 30-minute scoping call. No commitment, no boilerplate — just a conversation about your project and what you need.

Answers to common questions about cost estimating, ROM estimates, AI workflows, and how EstimaBuild works.
EstimaBuild is an independent construction cost estimating and AI workflow advisory firm. We help general contractors, developers, owners, and designers with Rough Order of Magnitude estimates, quantity takeoffs, AI tool selection, and workflow implementation — from early preconstruction through project execution.
We work with general contractors, specialty subcontractors, real estate developers, owners, and architects who need independent cost estimates or guidance on how to integrate AI tools into their preconstruction and construction workflows.
A ROM estimate is a high-level cost projection used before a project commits to full design or preconstruction. It establishes a defensible budget range — typically based on project scope, assumptions, and major exclusions — that allows owners, GCs, and lenders to make Go/No-Go decisions without a lengthy engagement.
A construction estimate is an owner-side planning tool that establishes expected project costs — used to set budgets, secure financing, and evaluate feasibility. A bid is a contractor-side pricing document submitted to win work. EstimaBuild produces independent estimates for owners and project teams, not bids for contractors.
Book a free 30-minute consultation through our Contact page. We'll review your current workflow or project needs, identify where we can help — whether that's a cost estimate, an AI tool evaluation, or a broader advisory engagement — and outline next steps. No retainer or long-term commitment required to get started.
Common AI tools in construction include platforms for automated cost estimating, bid leveling, RFI tracking, submittal review, schedule analysis, and field reporting. Examples include Procore, Autodesk Construction Cloud, Togal.AI, and others. EstimaBuild helps teams evaluate which tools are credible, affordable, and actually fit their workflow — rather than chasing hype.
AI can help if your team spends significant time on repetitive tasks like takeoffs, bid comparisons, or status reporting. A good indicator is whether errors or delays in these areas are costing you money or bids. EstimaBuild offers a free workflow assessment to identify where AI would have the most impact — without requiring you to invest in any software upfront.
An AI workflow advisory is a consulting service that maps your current construction workflows — estimating, scheduling, procurement, field ops — and identifies where AI tools can reduce time, cost, or errors. Rather than selling software, EstimaBuild acts as an independent advisor: evaluating tools, running pilots, and helping your team adopt what actually works.
It depends on scope, but most firms see meaningful results within 4–8 weeks. A workflow assessment takes 1–2 weeks. Piloting a single tool typically takes 2–4 weeks. Full advisory engagements run 6–12 weeks depending on project complexity and team readiness.
No. EstimaBuild works on a project-by-project basis. You can start with a single workflow assessment, a one-time cost estimate review, or a defined advisory scope — and expand from there only if it makes sense. There are no retainer requirements and no minimum commitment.
