Equipment Procurement and Lead Times

Navigation: phase-workflows | index

Procurement timing drives schedule and cost on manufacturing projects. Long-lead equipment must be identified early and ordered with enough runway to avoid driving the critical path. Lead times in 2025–2026 remain elevated across most electrical and mechanical categories.

2025–2026 Lead Time Reference Table

Data from Power Magazine transformer survey (Q2 2025), TD World switchgear report (Q2 2025), and AMG Engineering procurement scheduling guidance. All ranges represent order-to-delivery for standard-to-moderately-customized equipment.

Equipment Category	Lead Time Range	Avg (Q2 2025)	Notes
Power transformers (large, >10 MVA)	120–144 weeks	~128 weeks	Most constrained category; domestic capacity limited
Power transformers (medium, 2–10 MVA)	52–78 weeks	~65 weeks	Improved from 2023 peak but still elevated
Medium-voltage switchgear (5–15 kV)	26–52 weeks	~44 weeks	Custom bus configurations extend to high end
Low-voltage switchgear / MCCs	20–40 weeks	~30 weeks	Arc flash labeling and UL listing add 4–6 weeks
Motor control centers (custom)	24–44 weeks	~34 weeks	Variable speed drives integrated = longer
Custom pressure vessels (ASME VIII)	40–60 weeks	~50 weeks	Exotic metallurgy (Hastelloy, duplex SS) at high end
Heat exchangers (shell & tube, standard)	16–28 weeks	~22 weeks	Custom U-tube or floating head adds 4–8 weeks
Centrifugal pumps (large process)	16–26 weeks	~20 weeks	API 610 service = longer; ANSI = shorter
Positive displacement pumps (specialty)	20–36 weeks	~28 weeks	Sanitary/CIP-rated extends timeline
Industrial chillers (>200 tons)	30–52 weeks	~40 weeks	Refrigerant availability (A2L transition) affecting supply
Air-cooled heat exchangers	24–40 weeks	~32 weeks	Custom finned tube sections drive range
Packaged air compressors / dryers	12–20 weeks	~16 weeks	Largely off-the-shelf; custom skids add 8+ weeks
Boilers (industrial fire-tube, packaged)	20–36 weeks	~28 weeks	ASME stamping and startup training included
Conveyors / material handling systems	16–30 weeks	~22 weeks	Custom fabrication for food-grade or cleanroom extends

[!warning] Staleness Watch Lead times are highly volatile. Refresh this table quarterly using ENR, Power Magazine, and direct vendor inquiry. Last validated: Q2 2025.

Procurement Category Definitions (OFCI / OFOI / CFCI)

Category	Who Furnishes	Who Installs	Typical Use Case
CFCI — Contractor Furnished Contractor Installed	GC / CM	GC / CM	Standard mechanical, electrical, structural; low owner involvement
OFCI — Owner Furnished Contractor Installed	Owner	GC / CM	Long-lead equipment owner orders early to protect schedule; contractor installs
OFOI — Owner Furnished Owner Installed	Owner	Owner’s forces	Proprietary process equipment; owner has specialized install team or OEM controls installation
GFE — Government Furnished Equipment	Government agency	Contractor	Public sector projects; owner-procured under separate contract

When to use OFCI: Any equipment with lead time >26 weeks that falls on or near the critical path. Owner takes procurement risk (design changes, specification errors) in exchange for schedule protection.

Risk allocation note: OFCI shifts procurement risk to the owner. If specifications change after order, the owner absorbs the change order cost. Document equipment specifications in detail before issuing the purchase order.

Payment Milestone Structure

Standard progress payment schedule for major process equipment:

Milestone	Typical %	Trigger
Order placement / deposit	30%	Purchase order executed
Fabrication start confirmation	30%	Vendor confirms materials received, shop drawings approved
Factory acceptance test (FAT)	30%	Equipment passes FAT at vendor facility
Delivery and site receipt	10%	Equipment received on site, visual inspection passed

Some vendors (especially transformer manufacturers) require larger upfront deposits (40–50%) due to raw material costs. Negotiate FAT witness rights and punch list procedures before order placement.

When to Start Procurement

Lead Time	Action Trigger
>104 weeks (2+ years)	Begin procurement process before FEED complete — owner places letter of intent or preliminary PO at FEL-2/FEL-3 gate. Budget numbers must be locked enough to commit.
52–104 weeks (1–2 years)	Procure at FEL-3 / FEED completion — issue RFQ during FEED, award at FEED gate
26–52 weeks	Procure at GMP execution — issue RFQ with GMP documents, award within 30 days of GMP
<26 weeks	Procure during construction — standard bid process, no schedule risk

Consequence of missing the trigger: Each week of delay on a 52-week lead time item typically adds 1–2 weeks to the overall project schedule (depending on float available). For zero-float critical path items, it’s 1:1.

Price Lock and Escalation Risk

Long-lead equipment ordered early means prices are locked before construction cost inflation can be fully modeled. Strategies:

• Fixed-price PO with escalation clause: Protects against commodity surges during fabrication; vendor absorbs minor fluctuation, owner absorbs defined escalation triggers (e.g., steel PPI increases >15%)
• Price lock at order: Best for budget certainty; vendor may build in contingency
• Price at delivery: Not recommended for long-lead items — full escalation exposure during fabrication period
• Tariff pass-through clause: For imported equipment (European switchgear, Asian pressure vessels), include explicit contract language on tariff changes post-order. 2025 Section 232 tariffs (50% on steel/aluminum) affected fabricated equipment from Canada, EU, and Asia — see Material Escalation and Commodity Pricing

Procurement Checklist (Per Major Equipment Item)

• Lead time confirmed with at least 2 vendors
• Equipment on critical path or float identified (from Level 2 schedule)
• OFCI vs. CFCI determination documented in BOE
• Data sheet / specification issued for inquiry
• Budget-level cost established from at least 1 budgetary quote
• FAT requirements documented (witness, test procedures, punchlist process)
• Payment milestones agreed and in PO terms
• Site delivery logistics: size, weight, unloading equipment, lay-down area
• Import duties and customs broker identified (for imported equipment)
• Tariff exposure assessed and documented in BOE
