What does a special construction takeoff include?

Our special construction takeoffs include modular and pre-engineered structure quantities (module counts, panel SF, structural frame tonnage), clean room and controlled environment quantities (wall and ceiling panel SF, air lock and pass-through counts), RF/EMI shielded enclosure quantities (SF, panel counts, penetration and filter counts), aquatic facility quantities (pool shell SF, deck SF, gutter LF, mechanical equipment counts), and specialty enclosure quantities (blast-resistant and ballistic panel SF, vault door counts).

Do you provide estimates for modular and pre-engineered buildings?

Yes. Modular building system quantities (module counts, panel SF, connection hardware) and pre-engineered metal building quantities (frame tonnage, wall and roof panel SF, trim LF, door and window counts) are included when manufacturer drawings and specifications are supplied.

Do you provide estimates for RF/EMI shielded rooms?

Yes. RF/EMI shielded enclosure quantities are included when shielding drawings and specifications are supplied — shielded room SF, panel counts, door and penetration counts, and filter/waveguide unit counts. Shielding performance specifications are noted.

What file formats do you accept for special construction drawings?

We accept PDF, CAD (DWG/DXF), and most other common formats. Architectural drawings, structural drawings, manufacturer specifications, and equipment schedules are all needed for a complete special construction takeoff.

How much does a special construction estimate cost?

Fees are based on project size and scope complexity. We provide a fixed-fee quote before starting any work — no hourly billing, no surprises. Contact us with your drawings for a free fee proposal.

Q: Do you provide estimates for clean rooms?

Yes. Clean room and controlled environment quantities are included when clean room drawings are supplied — wall panel SF, ceiling grid SF, air lock unit counts, pass-through counts, and HVAC interface quantities. ISO classification and performance requirements are noted from the specification.

Q: Do you provide estimates for aquatic facilities and pools?

Yes. Aquatic facility quantities are included when aquatic drawings are supplied — pool shell SF, gutter LF, deck SF, mechanical room equipment counts, and specialty finish quantities. Natatoriums and competition pools are included.

Professional estimating for modular and pre-engineered structures, clean rooms, shielded enclosures, aquatic facilities, specialty enclosures, and other special construction scopes. Quantity-only and cost-estimate packages. 48–72 hour turnaround.

What's Included

Complete Special Construction Takeoff

Every special construction takeoff is 100% drawing-referenced — every modular unit, panel, enclosure component, and specialty system item tied to a specific drawing, specification, or equipment schedule.

Modular & Pre-Engineered Structures

Module counts, panel SF, structural frame tonnage, and connection hardware from manufacturer drawings and specifications.

Clean Rooms & Controlled Environments

Wall panel SF, ceiling grid SF, air lock unit counts, pass-through counts, and HVAC interface quantities from clean room drawings.

RF/EMI Shielded Enclosures

Shielded room SF, panel counts, door and penetration counts, and filter/waveguide unit counts from shielding specifications.

Aquatic Facilities & Pools

Pool shell SF, gutter LF, deck SF, mechanical room equipment counts, and specialty finish quantities from aquatic drawings.

Specialty Enclosures & Vaults

Vault panel counts, blast-resistant wall SF, ballistic panel SF, and specialty door counts from enclosure drawings.

Excel Workbook + Annotated PDF Markups

All quantities organized by CSI division and system, with annotated markups showing every counted item.

Why Choose Us

The Union Estimating Difference

Spec-Driven Quantities

Special construction scopes are specification-heavy. We read manufacturer specs, performance specs, and shop drawing packages — not just floor plans.

System-by-System Organization

Each special construction system is quantified and organized separately — clean room, shielding, aquatic, and modular quantities never mixed.

Fixed Fee Before We Start

We quote a firm fee after reviewing your drawings. No hourly billing, no scope creep surprises.

Quantity-Only or Cost Estimate

Receive measured quantities only, or add agreed material and labor pricing from our proprietary database and current supplier quotes.

48–72 Hour Turnaround

Standard delivery within 48–72 hours. Rush available. Contact us with your bid date.

Nationwide Coverage

We serve contractors, owners, and developers across all 50 states — any project size, any special construction scope.
