Manufacturing Plant Estimating

A warehouse estimate focuses on shell and slab, with minimal MEP. A manufacturing plant estimate adds process piping, equipment pads, pipe racks, heavy electrical distribution, and specialized HVAC. The takeoff must include Divisions 21 through 26 and Division 40, which are often not in warehouse scopes. We organize the estimate by CSI division so you can see the additional process scope clearly. For example, a warehouse may have a simple wet sprinkler system, while a plant might require a foam system for flammable liquids. Similarly, a warehouse slab is typically 6 inches with wire mesh, while a plant slab may be 8 inches with #5 bars at 12 inches on center. These differences significantly impact quantities and cost.

We exclude the equipment itself but include the foundations, supports, and utility connections. We take off anchor bolts, embedded plates, and pads from the structural drawings. We also measure the piping, conduit, and ductwork from the equipment connection to the tie-in point. This ensures your bid covers the installation scope while the vendor covers the equipment. For example, if a vendor supplies a 10,000 lb chiller, we would take off the concrete housekeeping pad, the anchor bolts, the vibration isolation, and the piping from the chiller to the nearest header. We also note any special requirements such as spring isolators or flexible connections.

Yes. We take off what is shown and note assumptions where coordination is missing. For example, if pipe routing is not final, we estimate from the equipment layout and note the assumed routing. We flag these as clarifications so you can adjust when the drawings are finalized. We do not guess quantities; we state what we measured and what we assumed. We also cross-check with other disciplines. If a pipe rack appears on process drawings but not structural, we note that the supports are not detailed and assume a standard support spacing. This approach gives you a defensible estimate that can be updated as the design progresses.

Turnaround is 24–48 hours for most projects. Larger projects with extensive process scope may take longer. Rush service is available. The time depends on the completeness of the drawings and the number of sheets. We confirm the schedule when you send the documents. For a typical 50,000 SF plant with 100 sheets, we can deliver in 48 hours. If the project includes complex process piping with hundreds of lines, we may need 3–4 days. We prioritize based on your bid deadline. You can send files through our get an estimate form, and we will confirm receipt and schedule within a few hours.

Yes. We take off cleanroom walls, ceilings, HEPA filters, and dedicated HVAC systems. We also include gowning airlocks, flooring, and special fire suppression. We separate clean and dirty utilities in the takeoff. Cleanroom requirements are typically in Division 13 Special Construction and Division 23 HVAC. For example, an ISO Class 7 cleanroom may require fan filter units, epoxy flooring, and a separate make-up air unit with HEPA filtration. We also account for the additional cost of sealed penetrations and cleanable surfaces. We note the ISO class and any gowning requirements from the specifications.

We trace each line from the equipment connection to the tie-in point. We record material, size, and schedule, and count valves and fittings. Welding inches are estimated from the number of joints. We separate clean and dirty utilities and note slope requirements. We also measure supports, hangers, and insulation where specified. For example, a 6-inch carbon steel line with 20 joints would have approximately 120 welding inches. We also account for field vs. shop welds and any special inspection requirements. If the drawings show pipe racks, we measure the rack steel separately under Division 05.

We include service entrance, switchgear, transformers, panelboards, feeders, and branch circuits. We measure conduit and wire from the one-line diagram and panel schedules. We also include lighting, controls, and fire alarm devices. Feeders to equipment are included from the panel to the equipment, even if they are shown on process drawings. For example, a 480V feeder to a 100 HP motor would be measured from the MCC bucket to the motor junction box, including conduit, wire, and terminations. We also note any special requirements such as harmonic filters or surge protection.

We measure runway beams by length and member size, and include rail, clips, stops, and electrification. We check the crane vendor drawings for capacity and span. We also note alignment tolerances and shim requirements. Runway beams are part of Division 05 Metals and are often shown on structural drawings. For example, a 50-foot span crane with a 20-ton capacity might require W24x94 runway beams with 60 lb/yard rail. We also include the crane stop, which is often a welded assembly. We verify the runway length matches the crane travel and building length.

We provide both quantities and unit costs. Pricing is ZIP-code-adjusted for material and labor, using RSMeans data. We deliver an Excel estimate with labor and material breakdowns. You can adjust the unit costs to match your own historical data or subcontractor quotes. For example, concrete in ZIP 78701 might be priced at $150 per CY, while in ZIP 10001 it could be $200 per CY. We also separate labor and material for each line item, so you can see the impact of wage rates. We do not mark up subcontractor quotes; we provide bare costs.

You receive an Excel estimate organized by CSI MasterFormat division, a PDF version, and marked-up plan sheets showing what we measured. We also include a list of assumptions and clarifications, and a takeoff backup showing how each quantity was derived. All deliverables are sent digitally. The Excel file includes tabs for each division, with columns for quantity, unit, unit cost, and total cost. The marked-up plans use clouding and annotations to show the boundaries of our takeoff. This allows you to quickly verify our scope and make adjustments.

Yes. We take off the new scope and include tie-ins to existing systems. We note where existing capacity may be limited and flag it as an assumption. We also include demolition and temporary works if shown. For tie-ins, we measure from the new equipment to the existing connection point. For example, if a new process line ties into an existing header, we measure the pipe from the new equipment to the tie-in point, including the tee and any valves. We also note if the existing system needs to be shut down, which may require temporary services. We recommend verifying existing capacities with the owner.

We need architectural, structural, process, and electrical drawings, plus specifications and the equipment list. If you have a one-line diagram and panel schedules, send those as well. The more complete the set, the more accurate the estimate. You can send files via our get an estimate form. We also need to know the project location for ZIP-code-adjusted pricing, and any special requirements such as LEED or seismic. If some drawings are missing, we can work with what you have and note the exclusions. We will confirm receipt and ask for clarifications if needed.

You receive an Excel workbook and PDF organized by CSI MasterFormat division, plus marked-up plan sheets showing where each quantity came from. The workbook lists line items with units, quantities, and notes on assumptions. For process work, we separate Division 40 interconnections from Division 22 plumbing and Division 44 pollution control so your subcontractor list lines up. We also flag addendum and RFI items that affect scope.

Yes. We take off equipment pads, anchor bolts, embeds, and utility connections from vendor submittals and the general arrangement drawing. We measure pipe runs to the equipment flange, note steam distribution and conveyor systems interfaces, and list electrical feeders by size and length. Where vendor data is incomplete, we state the assumption in the workbook so you can confirm before bid.

We organize quantities around the code families that drive scope: IBC and IRC for building, IECC for envelope and lighting, NEC for power, IPC or UPC for plumbing, NFPA 13 for sprinklers, and ASME B31.3 for process piping. OSHA requirements for access, guarding, and egress are noted where they add line items. Confirm the adopted code edition with the local building department before you price.
