CSI Process Divisions 40–48

Navigation: estimating-techniques | index

Divisions 40–48 are the process-specific extensions of CSI MasterFormat — used exclusively for industrial and manufacturing plant work. Unlike Divisions 03–33 (which cover building construction), these divisions cover the equipment, piping, and systems that make a manufacturing plant actually function. They represent the largest cost component of most manufacturing plant projects.

Key principle: A DB contractor pricing the building (Div 03–33) while the owner buys process equipment separately still must price Div 40 piping and Div 41 material handling to connect and serve that equipment. Never assume process divisions belong to the owner unless it’s in writing.

Division Map — Process-Specific Scope

Division	Title	Manufacturing Relevance	Primary Cost Drivers
40	Process Interconnections	Universal — every process plant	Process piping, valves, pipe supports, instrumentation tubing
41	Material Processing and Handling Equipment	Stamping, F&B, chemical, mining	Conveyors, cranes, hoists, feeders, mixers, size reduction
42	Process Heating, Cooling, and Drying Equipment	F&B, pharma, chemical, CPG	Heat exchangers, boilers, dryers, ovens, furnaces
43	Process Gas and Liquid Handling	F&B, pharma, chemical, refinery	Pumps, compressors, tanks, gas distribution systems
44	Pollution and Waste Control Equipment	Paint shop, chemical, F&B	VOC/RTO systems, scrubbers, wastewater pre-treatment
45	Industry-Specific Manufacturing Equipment	Automotive, pharma, semiconductor	Custom production equipment, process-specific tooling
46	Water and Wastewater Equipment	F&B, pharma	Treatment systems, filtration, membrane systems
48	Electrical Power Generation	All large plants	Emergency generators, UPS, on-site power generation

Division 47 (not listed) covers Solid Waste Management — less common in manufacturing DB scope.

Division 40 — Process Interconnections (The Most Common Process Division)

This is the division that most DB contractors price but least understand. It covers all piping, valves, and fittings that connect process equipment — the “circulatory system” of the plant.

Key Sub-Sections

• 40 05 — Common Work for Process Interconnections (pipe supports, field instruments, testing)
• 40 10 — Gas and Vapor Process Piping
• 40 20 — Liquid Process Piping (most common in F&B, pharma, CPG)
• 40 30 — Solid and Mixed Material Process Piping
• 40 40 — Process Piping Valves (gate, globe, ball, butterfly, control valves)
• 40 42 — Process Piping and Equipment Insulation

Estimating Approach

Class 5 / Class 4: Use percentage of major equipment cost

• Carbon steel process piping: 25–40% of major equipment FOB cost
• Stainless (food-grade / pharma): 40–65% of major equipment FOB cost
• This is incorporated into Lang/Hand factor method

Class 3: Use P&ID pipe count × diameter × linear-foot unit rate

• Carbon steel schedule 40, 2” diameter: $80–$130/LF installed (material + labor, 2025)
• 304 SS schedule 10, 2” diameter: $120–$200/LF installed
• 316L SS BPE fitting-grade, 2” diameter: $200–$350/LF installed
• Add 30–50% for small-bore (<1”) instrumentation tubing

Class 2: Full material takeoff from P&IDs — count every fitting, valve, and linear foot by diameter and spec

Division 41 — Material Processing and Handling Equipment

Covers powered equipment that moves, processes, or handles materials within the facility.

In-scope for GC unless OFCI:

• Conveyor systems (belt, roller, chain, overhead)
• Overhead cranes and hoists
• Dock equipment (levelers, seals, restraints)

Usually OFCI (Owner-Furnished, Contractor-Installed) or OFOI:

• Production equipment (presses, mixers, packaging lines)
• Custom process machinery

Installation Cost Factors (when GC installs OFCI equipment)

• Mechanical installation: 8–20% of equipment FOB cost (varies by equipment complexity)
• Electrical rough-in: 2–5% of equipment FOB cost
• Foundations and anchor bolts: 1–4% of equipment FOB cost
• Coordination/commissioning allowance: 2–3% of equipment FOB cost

---

Division 42 — Process Heating, Cooling, and Drying

Common in F&B (pasteurizers, ovens, dryers), pharma (lyophilizers, sterilizers), and CPG (coating equipment).

Key cost items that belong here:

• Boiler plant and steam distribution
• Process heat exchangers (shell-and-tube, plate-and-frame)
• Industrial ovens and dryers
• Refrigeration packages (air-cooled chillers, ammonia systems)

Estimating approach: Equipment FOB × installation factor (1.3–2.0 depending on complexity)

• Shell-and-tube heat exchangers: installation factor 1.4–1.6
• Industrial dryers: installation factor 1.5–2.0
• Boiler plant (packaged): installation factor 1.3–1.5

---

Division 43 — Process Gas and Liquid Handling

Pumps, compressors, tanks, and distribution systems. In food processing and pharma, this includes compressed air systems, nitrogen systems, and CO₂ systems.

Compressed air (food-grade ISO 8573-1): Oil-free compressor + desiccant dryer + stainless distribution

• Complete packaged system: $15,000–$45,000/installed SCFM (see Food and Beverage page for detail)

Industrial tanks (SS, atmospheric): $3,000–$12,000/tank (material) × 1.3–1.5 installation factor

---

Division 44 — Pollution and Waste Control Equipment

Critical for automotive paint shops, coating operations, aerosol products, and any process with VOC or particulate emissions.

RTO (Regenerative Thermal Oxidizer) — the dominant VOC control technology:

• Installed cost: $800,000–$3,000,000 depending on airflow capacity
• Typically 5–10% of total paint shop TIC
• Lead time: 18–30 weeks
• AHJ permit review required before construction

Dust collection (NFPA 652/654 compliant) — for dry goods, grain, powder:

• Baghouse or cartridge collector: $50,000–$400,000 installed depending on CFM and explosion-proof requirements

---

Division 45 — Industry-Specific Manufacturing Equipment

This is where custom production equipment lives — presses, injection molds, pharmaceutical process trains, semiconductor equipment. Usually OFOI (Owner-Furnished, Owner-Installed) or procured directly by owner.

GC scope within Division 45 is typically limited to:

• Equipment foundations and anchor bolt templates
• Utility rough-ins (compressed air, electrical, chilled water, drain) to equipment connection point
• Crane or rigging required for placement

How to Scope Divisions 40–48 in a GMP

Before setting the GMP, answer in writing for each process division:

Question	Answer needed
Is process equipment in GMP or OFCI/OFOI?	Defines what Division 41/45 scope belongs to GC
Does GC provide utility rough-ins to equipment?	Defines cutover point for Div 40 piping
Who provides RTO/VOC controls?	Defines Div 44 scope
Is installation of OFCI equipment in GMP?	Defines labor-only scope for installed equipment
Who owns commissioning and startup?	Separate from construction; must be defined

The most common scope gap: Owner assumes the GC is not pricing Division 40 process piping because the owner is buying process equipment separately. Unless explicitly excluded from the GMP scope, the GC may be on the hook for all process interconnections piping.
