Emission and waste-control equipment estimates that carry the whole installation
A baghouse purchase order is a fraction of the installed cost. Foundations, platforms, ducting to the stack, insulation, compressed air, instrumentation, electrical feeds and a crane lift come on top. We price pollution control projects from the process data and equipment datasheets, then quantify every interface so plant managers, EPC firms and contractors can see the full installed number before committing to a permit-driven schedule.

Overview
Estimating environmental equipment installations
Division 44 covers equipment that captures, treats or destroys airborne and waterborne pollutants.
Air systems include baghouses, cartridge collectors, wet and dry scrubbers, cyclones, electrostatic precipitators and thermal or catalytic oxidizers. Water systems include equalization tanks, clarifiers, dissolved air flotation, filtration and sludge handling. Equipment is usually specified by performance: airflow in ACFM, particulate loading, removal efficiency and discharge limits.
That performance basis makes the estimate depend on vendor input. We use the process data sheet to establish equipment size, request or apply budget pricing, and then quantify what the vendor excludes. Typical exclusions include concrete pads and pilings, structural steel supports and stair towers, ductwork and expansion joints, fans and dampers, stack extensions, insulation and lagging, process piping and electrical gear.
Installation labor is driven by weight, access and lift. We estimate crane tonnage and duration, field assembly of modular sections, welding of duct and stack, and hours for alignment, leak testing and instrumentation loops. Commissioning, source testing for permit compliance and operator training are carried as separate lines so the schedule reflects the regulator's deadline.

Process
How our estimating process works
Four steps from upload to a bid-ready estimate, with a senior estimator signing off before anything leaves our desk.
Upload plans and scope
- 1
Step 1
Upload plans and scope
Send your drawings, specifications and bid invitation through the secure upload form. We confirm scope, deadline and a fixed price within two business hours.
- 2
Step 2
Digital quantity takeoff
Estimators measure every item from calibrated plans in Bluebeam and PlanSwift, color-coding each layer so quantities can be traced back to the drawing.
- 3
Step 3
Pricing and labor
Quantities are priced with location-adjusted material costs, crew productivity rates and equipment, then marked up to your overhead and profit targets.

Step 4
Senior review and delivery
A second estimator audits quantities and pricing, documents assumptions and exclusions, and delivers your Excel workbook, PDF summary and marked-up plans.

Why LEEDS
Why contractors switch to LEEDS
An estimating desk that behaves like an extension of your team, not a software subscription.
Performance-spec equipment is sized from airflow, loading and efficiency, then compared against vendor budgets for reasonableness.
Foundations, platforms, ducts, stack sections, and insulation are quantified separately, since vendors seldom include them.
Rigging is priced from equipment weights, crane radius and access conditions rather than a flat percentage.
Welding and fabrication labor is estimated, by pound of duct and by linear foot of stack for carbon and stainless materials.
Instrument loops, PLC integration and electrical, feeds are counted so process controls are not left as owner allowances.
Permit-driven testing and startup are included, which protects compliance deadlines and schedule assumptions.
Experience with both air and water treatment, equipment keeps combined plant projects in one estimate.

FAQ
Pollution Control Equipment Estimating FAQs
How do you estimate equipment specified by performance?
We start with the process data: airflow, temperature, particulate or pollutant loading and required removal efficiency. That sets the equipment size. We then apply vendor budget pricing and add the installation scope the vendor excludes, noting each assumption so the final quote can be matched line by line.
What does a baghouse estimate include beyond the unit?
Foundation or pad, support steel, access platforms, inlet and outlet ductwork, fans, dampers, insulation, compressed air, instrumentation, electrical feeds, rigging and startup are all quantified. Our scope matrix lists what the vendor supplies and what the contractor must furnish.
Can you price wastewater treatment equipment?
Yes. We price tanks, clarifiers, dissolved air flotation, filtration, pumps, chemical feed skids, process piping, and the concrete and electrical work that supports them. Equipment is sized from flow in gallons per minute and the treatment train shown on the process flow diagram.
How is crane and rigging cost determined?
We use equipment weights, pick radius, site access and number of lifts to select crane capacity and duration. Modular sections, stacks and rooftop equipment each get a lift line, so rigging cost follows the sequence of installation rather than a lump-sum percentage.
Do you include source testing and permits?
Startup, leak testing and stack testing allowances are included when the specification requires them. Permit applications and engineering fees are not part of the estimate unless requested, but we identify the compliance milestones that control the installation schedule.
Can you estimate work in an operating plant?
Yes. We account for outage windows, hot work permits, limited laydown, shift premiums, demolition of existing equipment and tie-ins to live ductwork. These conditions change productivity, so they are carried as explicit adjustments in the labor build-up.
