Cost Estimating & Quantity Takeoffs
AACE-standard estimates and independent quantity takeoffs, from early feasibility through bid-ready documentation. Every output is reviewed by a certified estimator.
Estimate Classes
We Deliver Across the Full Estimate Class Spectrum
AACE International defines five estimate classes by design maturity and expected accuracy. We deliver the full spectrum, Class 5 (ROM) through Class 1 (Definitive), and support contractor and bid-scope estimates when needed.
Conceptual / ROM
0–2% design complete
Schematic
1–15% design complete
Budget / DD
10–40% design complete
Control / CD
30–70% design complete
Definitive
65–100% design complete

Scope of Services
What Every Estimate Includes
We don't send you a spreadsheet and call it done. Every estimate comes with the documentation that makes it defensible.
Written Basis of Estimate
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 Analysis
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.
Vendor-Verified Pricing
We work directly with trade subcontractors to verify pricing for key scopes, giving our estimates real market grounding beyond published cost databases.
CSI Division Breakdown
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.
Value Engineering Options
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.
Escalation & Risk Notes
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.
Sector Expertise
Specialized Estimating for Complex Sectors
Data Center & Mission Critical
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.
Industrial & Infrastructure
Heavy civil, process facilities, and large-scale infrastructure projects where unit cost databases alone are insufficient and direct sub pricing relationships are essential.
Institutional & Federal
Government facilities, federal programs, and institutional projects where AACE methodology, documentation rigor, and defensible contingency analysis are non-negotiable.
Data Center Cost Estimating
Low Voltage & MEP Estimating for Data Centers
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.
What a Data Center Estimate Covers
- ✓Structural shell and core construction
- ✓Power distribution: switchgear, UPS, PDU, generators
- ✓Cooling: precision AC, CRAC/CRAH, chilled water systems
- ✓Low voltage: structured cabling, fiber, cable management
- ✓Security: access control, CCTV, intrusion detection
- ✓BMS / DCIM integration and controls infrastructure
- ✓Fire suppression (clean agent, pre-action)
