GC vs Subcontractor Equipment Procurement

Equipment procurement responsibility varies by contract type: subcontractors handle it on design-bid-build; GCs on design-build. GFSI (GC-furnished/sub-installed) divides procurement and installation risk. Cross-visibility matters for schedule.

Short answer: Equipment procurement responsibility depends on contract structure.

In design-bid-build, MEP subs typically procure all equipment within their scope. In design-build and CM-at-risk, GCs may procure major equipment directly.

Some owners furnish high-value equipment themselves.

Regardless of who procures, both GCs and subs benefit from shared visibility into equipment decisions: the GC gets schedule confidence and cost control, the sub gets clearer specs and faster submittals.

How contract structure determines the split

There's no universal rule for who procures equipment on a construction project. It depends on the delivery method and the specific contract language between the owner, GC, and subcontractors.

Design-bid-build

In traditional design-bid-build, the owner hires an architect/engineer to produce complete construction documents, then bids the project to GCs. The GC wins the bid and subcontracts the MEP trades.

In this structure, MEP subcontractors typically procure all equipment within their trade scope. The mechanical sub buys the chillers, AHUs, and pumps. The electrical sub buys the switchgear, transformers, and generators. The plumbing sub buys the water heaters and pumps.

The GC's contract with the sub includes the equipment cost in the subcontract value. The sub selects vendors, manages quotes, processes submittals through the GC to the engineer, and issues purchase orders.

The GC has limited visibility into the sub's vendor selection, pricing, or lead time management unless they specifically request it.

Design-build

In design-build, the GC (or a design-build entity) carries both design and construction responsibility. This gives the GC more control over equipment selections because they're involved earlier in the design process.

GCs in design-build projects often procure major equipment directly, especially long-lead items like chillers, switchgear, and generators, because they have both the authority and the incentive to manage lead times and costs at the project level.

The sub's role in design-build is more installation-focused. Equipment may be GC-furnished/sub-installed (GFSI), where the GC procures and the sub installs.

CM-at-risk / GMP

Under a CM-at-risk or guaranteed maximum price (GMP) contract, the GC serves as construction manager and guarantees a maximum price to the owner. This creates a strong incentive for the GC to control equipment costs.

GCs in CM-at-risk arrangements often take a more active role in equipment procurement, either procuring directly or requiring subs to provide full transparency into their equipment pricing and vendor selections.

Some GMP contracts include allowances for specific equipment categories. The GC manages the allowance, selects vendors, and any savings or overruns against the allowance affect the GC's margin.

This makes equipment procurement a direct GC responsibility even when the sub handles installation.

Owner-furnished equipment

On some projects, the owner procures high-value equipment directly. This is most common for:

Owner-furnished equipment is typically assigned to the GC or sub for receiving, storage, setting, and connection, creating a split responsibility that requires careful coordination.

Quick comparison

Aspect GC-Procured Sub-Procured Owner-Furnished
Typical equipment Major items: chillers, generators, switchgear All equipment within trade scope Specialty or high-value items
Common in Design-build, CM-at-risk/GMP Design-bid-build Healthcare, data centers, institutional
Vendor selection GC controls Sub controls Owner controls
Lead time visibility Direct control by GC Depends on sub reporting to GC Owner manages; GC coordinates delivery
Cost visibility GC sees actual equipment costs GC sees subcontract value only Owner sees actual costs; GC does not
Submittal management GC manages directly with vendor Sub manages; GC reviews and forwards Owner manages; GC coordinates
Risk carrier GC carries procurement risk Sub carries procurement risk Owner carries procurement risk

Why GCs want visibility even when subs procure

Even when the subcontract structure puts equipment procurement squarely in the sub's scope, the GC has legitimate reasons to want visibility:

Schedule risk

If the mechanical sub's chiller is 4 weeks late, the GC's project schedule is 4 weeks late. The GC is the party accountable to the owner for the completion date.

Without visibility into the sub's equipment lead times, the GC can't identify schedule risks until they become schedule problems. By then, mitigation options are limited and expensive.

Cost control and demand aggregation

A GC running 15 active projects might have mechanical subs on each project buying equipment from the same manufacturers through different reps.

With visibility across all projects, the GC can aggregate demand ("we're buying 20 AHUs from your product line this year across these projects") and negotiate better pricing. Without visibility, each sub negotiates independently, and the GC misses the volume advantage.

Change order defense

When a change order dispute arises ("the spec changed, and the equipment cost more"), the GC needs to know what was originally procured, at what price, and what the change requires.

If the GC has no visibility into the sub's original equipment procurement, defending or evaluating the change order is harder.

Owner reporting

Owners increasingly ask for procurement status updates: What's been ordered? What's the delivery date? Are there lead time risks?

If the GC can't answer because the data lives inside the sub's email and spreadsheets, it erodes the owner's confidence in the project team.

The sub's perspective

From the sub's side, the resistance to sharing equipment procurement data is understandable and usually comes down to three concerns:

These are legitimate concerns.

Any visibility arrangement needs to address them directly, either through contractual protections (GC doesn't use sub pricing data in future bids), through mutual benefit (the sub gets something in return for sharing data), or through reducing the administrative burden (data flows automatically rather than requiring manual entry).

How shared visibility helps both sides

When it works, shared equipment visibility creates value for both parties:

What the GC gets

What the sub gets

The contract language that matters

Procurement responsibility is defined in the contract, and the specific language matters. Look for these terms:

Each arrangement creates different responsibilities for procurement timing, submittal management, lead time tracking, and delivery coordination.

Make sure the contract language is clear on who does what. Ambiguity here is a reliable source of disputes.

Frequently Asked Questions

Who procures equipment on construction projects?

It depends on the contract structure. In design-bid-build, MEP subcontractors typically procure all equipment within their trade scope. In design-build and CM-at-risk, the GC may procure major equipment directly. Some owners furnish high-value equipment (generators, emergency power) and assign it to the GC or sub for installation. Look at the contract language (GC-furnished/sub-installed vs. sub-furnished/sub-installed) to determine who carries the procurement responsibility on a specific project.

Why do GCs want visibility into sub procurement?

Four primary reasons: schedule risk management (if the sub's equipment is late, the GC's schedule is at risk), cost control through demand aggregation across projects and subs, change order defense (knowing what was procured at what price), and owner reporting (providing accurate procurement status without manual data collection from each sub).

What does GC-furnished/sub-installed mean?

GC-furnished/sub-installed (GFSI) means the general contractor procures the equipment (selects the vendor, issues the purchase order, manages the submittal process) and the subcontractor is responsible for receiving, setting, and connecting it. This splits procurement risk (carried by the GC) from installation risk (carried by the sub). It's common for major equipment like chillers, switchgear, and generators on large commercial projects.

How do subs protect their margins when sharing equipment data?

Legitimate concern. Some approaches that work: contractual protections that prevent the GC from using sub pricing data in future bid evaluations, sharing status and specification data without raw vendor pricing, and using platforms that provide visibility into equipment selections and lead times without exposing the sub's cost structure. The key is finding arrangements where the sub gets value (faster submittals, clearer specs, coordinated delivery) in exchange for the visibility the GC needs.

Which delivery method gives the GC the most control over equipment procurement?

Design-build gives the GC the most control because they're involved in both design and construction. They can influence equipment selections during design, procure directly, and manage lead times from the start. CM-at-risk/GMP is second, because the guaranteed price creates a financial incentive for the GC to control equipment costs. Design-bid-build gives the GC the least control: procurement sits with the subs, and the GC's influence is limited to specification enforcement and submittal review.
