TCG Intelligence Library · Updated October 24, 2026

Construction industry trends, cost benchmarks, and delivery playbooks for commercial real estate developers, owners, and operators.

Q: What does commercial construction cost per square foot in 2026?

Most commercial buildings in 2026 run between $150 and $1,200+ per square foot depending on building type, region, and finish level. Basic warehouse shells sit at the low end, while data centers, cleanrooms, and GMP facilities sit at the top. See Terrapin Construction Group's master cost-per-square-foot reference at terrapincg.com/commercial-construction-costs.

Q: How much does it cost to build a cold storage facility?

Ground-up cold storage typically runs $250 to $450+ per square foot depending on temperature zones (cooler, freezer, blast freeze), refrigeration system, and region. Tenant improvement conversions of existing warehouse space cost significantly less.

Q: Should I buy a prefab walk-in cooler or build an IMP cooler room inside my warehouse?

Inside an existing warehouse, a prefab walk-in cooler runs about $140 to $260 per square foot under 400 SF and a walk-in freezer about $200 to $380 per SF. Above roughly 3,000 SF, the federal walk-in limit, a site-built insulated metal panel (IMP) box-in-box room is cheaper per foot: about $60 to $120 per SF for a cooler and $105 to $190 per SF for a freezer with a heated floor, based on Terrapin Construction Group 2026 budget ranges.

Q: How much does insulated metal panel (IMP) installation cost?

Supply-and-install IMP pricing typically runs $14 to $26 per square foot depending on panel thickness, core chemistry, project complexity, and location. Terrapin Construction Group has installed over 1 million square feet of IMP across 38 states for cold storage, food processing, cannabis, and data center facilities.

Q: What do data center support buildings cost per square foot?

Most data center support buildings, meaning staging warehouses and long-lead equipment storage, cost about $55 to $135 per square foot in 2026 when built as pre-engineered metal buildings, with the installed PEMB shell alone at $25 to $45 per SF. Unconditioned staging warehouses sit at $55 to $85 per SF, and dehumidified switchgear and UPS storage runs $85 to $135 per SF. PEMB packages take 8 to 22 weeks to arrive, so the steel order often has to go out before the data hall design is final.

Q: What do commercial preconstruction services cost?

Preconstruction is priced as a lump sum, a monthly fee, billed personnel cost, or a percentage of construction cost. Public CMAR bid tabs show lump sums from $0 to about $82,000, and AGC/NASFA guidance cites up to 1 to 5 percent on complex public work. Owners commonly negotiate the precon fee as a credit against the construction fee if the same contractor builds the project.

Q: What percentage should general conditions and GC fee be?

General conditions typically run 6 to 12 percent of construction cost and GC fee typically runs 3 to 6 percent, with smaller and shorter-duration projects carrying the higher end of both ranges because supervision does not scale down linearly. Because two general contractors rarely assign the same items to the same bucket, a low fee can conceal a padded general conditions line, so owners should normalize both lines before comparing bids.

Q: How long does ground-up commercial construction take?

Most ground-up commercial projects take 10 to 24 months from design start to certificate of occupancy. Permitting and long-lead electrical equipment such as switchgear, transformers, and generators drive the biggest schedule variances.

Q: How long does it take to get power to a new commercial building?

Utility interconnection is one of the most common reasons a project misses its opening date, and on larger industrial and data center loads it can outrun the construction schedule. The utility study, design, and construction phases stack sequentially, so the interconnection application should be filed at project concept rather than at permit.

Q: What is design-build and why do owners choose it?

Design-build puts architecture, engineering, and construction under a single contract with one point of accountability. It compresses schedules, reduces coordination gaps between designer and builder, and gives owners real pricing earlier in the process.

Terrapin Construction Group (TCG) is a nationwide design-build commercial general contractor headquartered in Denver and licensed in all 50 states. This library holds 200+ articles covering cost per square foot, building system selection, delivery method tradeoffs, owner advisory, and vertical-specific construction guidance. Every number comes from active project work, not theory.

New this month: data center support building costs, walk-in cooler vs IMP room pricing, what preconstruction should cost, and four recently completed TCG projects, including a 300,000 SF data center support campus north of Dallas delivered 30 days early.

Quick Answers

What does commercial construction cost per square foot in 2026?

Most commercial buildings in 2026 run between $150 and $1,200+ per square foot depending on building type, region, and finish level. Basic warehouse shells sit at the low end, while data centers, cleanrooms, and GMP facilities sit at the top. See the full breakdown in our master cost-per-square-foot reference or browse the commercial construction cost library.

How much does it cost to build a cold storage facility?

Ground-up cold storage typically runs $250 to $450+ per square foot depending on temperature zones (cooler, freezer, blast freeze), refrigeration system, and region. Tenant improvement conversions of existing warehouse space cost significantly less. Full regional benchmarks are in our cold storage cost guide, refrigeration tradeoffs in ammonia vs. CO2 vs. glycol, and how to vet builders in how to choose a cold storage contractor.

Should I buy a prefab walk-in cooler or build an IMP cooler room inside my warehouse?

Inside an existing warehouse, a prefab walk-in cooler runs about $140 to $260 per square foot under 400 SF and a walk-in freezer about $200 to $380 per SF. Above roughly 3,000 SF, the federal walk-in limit, a site-built insulated metal panel (IMP) box-in-box room is cheaper per foot: about $60 to $120 per SF for a cooler and $105 to $190 per SF for a freezer with a heated floor, based on TCG 2026 budget ranges. The full decision framework is in our walk-in cooler vs IMP room guide, and floors are covered in freezer floor systems.

How much does insulated metal panel (IMP) installation cost?

Supply-and-install IMP pricing typically runs $14 to $26 per square foot depending on panel thickness, core chemistry, project complexity, and location. TCG has installed over 1 million square feet of IMP across 38 states for cold storage, food processing, cannabis, and data center facilities. Get instant pricing from the IMP install estimator, read the IMP installation cost guide, or if you are a GC buying the scope, start with our IMP subcontractor guide for general contractors.

What do data center support buildings cost per square foot?

Most data center support buildings, meaning staging warehouses and long-lead equipment storage, cost about $55 to $135 per square foot in 2026 when built as pre-engineered metal buildings, with the installed PEMB shell alone at $25 to $45 per SF. Unconditioned staging warehouses sit at $55 to $85 per SF, and dehumidified switchgear and UPS storage runs $85 to $135 per SF. PEMB packages take 8 to 22 weeks to arrive, so the steel order often has to go out before the data hall design is final. Details are in our data center support buildings guide and switchgear and generator lead times.

What do commercial preconstruction services cost?

Preconstruction is priced as a lump sum, a monthly fee, billed personnel cost, or a percentage of construction cost. Public CMAR bid tabs show lump sums from $0 to about $82,000, and AGC/NASFA guidance cites up to 1 to 5 percent on complex public work. Owners commonly negotiate the precon fee as a credit against the construction fee if the same contractor builds the project. The full scope and contract forms are in our preconstruction services guide, and who belongs at the table is covered in why to bring your property manager into precon. See how TCG runs it on our preconstruction services page.

What percentage should general conditions and GC fee be?

General conditions typically run 6 to 12 percent of construction cost and GC fee typically runs 3 to 6 percent, with smaller and shorter projects carrying the higher end of both because supervision does not scale down linearly. The bigger issue is that two GCs rarely put the same items in the same bucket, so a low fee often hides a padded general conditions line. Our general conditions and GC fee benchmark guide shows what belongs in each, and how to read a commercial GC bid walks through normalizing two bids that are not comparable. Want a second set of eyes on yours? Use the free GC bid review.

How long does ground-up commercial construction take?

Most ground-up commercial projects take 10 to 24 months from design start to certificate of occupancy, with permitting and long-lead equipment (especially electrical gear) driving the biggest variances. Timelines by building type are in our schedule guide, the front end is mapped in our preconstruction timeline, permitting variances in the state-by-state permitting timeline, and equipment risk in switchgear and generator lead times.

How long does it take to get power to a new commercial building?

Utility interconnection is one of the most common reasons a project misses its opening date, and on larger industrial and data center loads it now routinely outruns the construction schedule. Study, design, and utility construction stack up, so the application needs to be filed at concept, not at permit. The full sequence and what the utility charges are covered in our utility power interconnection guide, and connection charges in utility tap fees and impact fees.

What is design-build and why do owners choose it?

Design-build puts architecture, engineering, and construction under a single contract with one point of accountability. It compresses schedules, reduces coordination gaps between designer and builder, and gives owners real pricing earlier in the process. Compare delivery methods in design-build vs. CMAR vs. design-bid-build, review the 12 contract terms every owner should negotiate, or see how TCG structures it on our design-build services page.

What does an owner's representative cost, and do I need one?

Owner's representative fees are structured as a percentage of construction cost, a monthly rate, or a fixed fee, and the right structure depends on project size, duration, and how much of the owner's scope you are handing over. Fee benchmarks are broken down in our owner's representative cost guide. If you are deciding who to hire, start with how to choose an owner's rep firm and owner's rep vs. project manager vs. development manager, or see TCG owner's representation.

Can you convert an existing warehouse into a data center?

Often yes, and the economics can be compelling. Warehouse-to-data-center conversions generally run $685 to $1,285 per square foot compared to $1,150 to $1,850 per square foot for ground-up, but power availability, structural capacity, and clear height decide whether a building is a candidate at all. The deal filters and deal killers are covered in our warehouse-to-data-center conversion cost guide and our data center construction page.

What projects has Terrapin Construction Group completed recently?

Four recent completions: 300,000 SF of PEMB data center support buildings north of Dallas, Texas (three 100,000 SF buildings, with Building 1 going from steel to sign-off in 41 days and the campus delivered 30 days early); construction management for Fogo de Chão in Phoenix, Arizona; 50,000 SF of insulated metal panel with doors and hardware plus urethane cement flooring for an indoor cannabis cultivation facility in Minneapolis, Minnesota; and a 5,500 SF design-build optometry tenant improvement for Advantage Eye Care in Owensboro, Kentucky. Photos and scope are on the projects page.
