Preconstruction and Estimating for Boulder Valley Projects

Pricing a Boulder Valley building means pricing the review process as well as the structure. Two parcels a few miles apart can fall under different code editions, different energy rules, different floodplain regimes and different utility districts, and each difference moves the budget. An estimate that ignores them is a number that will be revised in the first month of plan review.

Our preconstruction work is meant to find those differences while the owner can still act on them: choose another parcel, change the building shape, adjust the delivery method or reserve a contingency that reflects the risk. We provide it as a paid service ahead of a construction contract or bundled with one, and the output is a budget the owner can take to a lender, a board or a council with confidence.

What a preconstruction engagement contains

The first deliverable is a site and jurisdiction memo: the code edition, the energy code, floodplain and drainage status, height and use limits, utility availability and any overlay districts. The second is a conceptual estimate built from quantities and from current subcontractor pricing, not only from a per-square-foot assumption. The third is a risk register in which each item has an owner, a cost range and a date by which the answer is needed.

As design develops, we update the estimate at each milestone and reconcile it against the previous one so the owner sees why the number changed. We also perform constructability reviews with our superintendents and key subcontractors. Whether the project then proceeds as design-build delivery or under another delivery method, the same team continues, and the carry-over of knowledge is a large part of the value.

Costs that are easy to miss

Four items surprise owners most. The first is the energy code: new commercial projects in the City of Boulder must be all-electric or use non-fossil sources, with exceptions for commercial cooking, hospitals, labs, large S-1 occupancies and emergency generators, and all-electric buildings must perform 10 percent better than ASHRAE 90.1-2022, with the mixed-fuel exceptions required to reach 15 percent. The second is floodplain work, because a Floodplain Development Permit applies to any structure in the 100-year floodplain, including footings and overhangs.

The third is offsite infrastructure, including road improvements, utility extensions and stormwater detention. The fourth is escalation and lead time on electrical gear. We include each as a specific line, with a range, so they do not hide inside a contingency. Developers who evaluate several parcels receive the same comparison for each one, and commercial real estate developers use that to rank sites.

Delivery method and the owner's decisions

Preconstruction is where the delivery method gets chosen. A fixed design with a clear scope suits a lump-sum bid. An evolving program suits a construction manager at risk, covered in CM at-risk construction management, where we advise during design and then commit to a guaranteed maximum price. A project where the owner wants one point of responsibility for design and construction suits design-build.

The owner also decides on procurement of long-lead items, early site packages and the tolerance for cost risk. We lay out the options with their effect on cost, schedule and risk, and we recommend one. For public owners, procurement law may restrict the choice, and we explain what is permitted before any proposal is prepared. School projects and other public work follow their own rules.

Which code applies to which parcel

Colorado has no single commercial building code. Jurisdictions adopt their own editions, and a January 2026 code tracker kept by a regional home builders association shows a wide spread: some places on the 2018 I-codes, some on 2021 and some on 2024. Within the Boulder market, Boulder and Louisville are on the 2024 IBC, Lafayette and Longmont on the 2021 edition with 2024 adoption planned, Erie on 2021, and Superior shown on 2018. For Superior the town's own page and the tracker conflict, so we confirm with the planning department.

The City of Boulder's 2024 I-codes took effect August 1, 2025, with a 2024 City of Boulder Energy Conservation Code effective December 1, 2024, and its amended 2026 National Electrical Code effective August 1, 2026. State law adds the HB22-1362 requirement that any jurisdiction updating its code after July 1, 2023 adopt an energy code at least as strong as the 2021 IECC. These dates affect when a permit application is vested, so we track them closely for projects near Boulder and Superior.

Fitting design, review and procurement together

The preconstruction schedule is a plan for the plan. We map design phases, owner approvals, design review boards, permit submissions, utility applications and procurement orders on one calendar, with durations drawn from recent local experience and from what each reviewer has told us. We also mark decision dates: the last day an owner can change the structural system without a redraw, for example.

Long-lead items such as electrical equipment, curtain wall and elevators may need to be ordered before permit approval, with the owner accepting some risk. We describe this trade-off with specific numbers. Sitework often starts early too, and our team can price it as a separate package, linked to site development and utilities.

Using local pricing, not national averages

National cost data misses the local patterns. The Boulder Valley has a design review culture that adds time to many projects, while the plains towns to the east tend to have more open land. Mixed-use and housing projects bring their own cost structures, which we discuss under multifamily and mixed-use buildings.

We keep current pricing from the subcontractors who work here and ask them to review scopes before we publish numbers. This is slower than using an index, but it produces estimates owners can rely on when bids arrive. We tell owners when a number rests on a single quote or an assumption, so they can judge the risk.

Ask for the jurisdiction memo

Name the parcel or the shortlist and the building you have in mind. We will return a code and review memo and a conceptual budget range you can use for decisions.

Questions Owners Ask

How accurate is a conceptual estimate?

It depends on the stage and the information. At concept stage, expect a range, often with a wide spread, which tightens as the design develops. We state the range and the assumptions, and we update at each milestone.

Do you charge for preconstruction?

We offer it as a stand-alone paid service or as part of a construction agreement, depending on the project. We will discuss the arrangement at the first meeting.

What if the estimate exceeds the budget?

We propose options: scope reductions, alternates, a different structural system, phasing, or value engineering with the design team. Each option comes with a price and a schedule effect so the owner can decide.

How do you handle code changes during design?

We track adoption dates, and where possible we help the owner understand whether the application will be reviewed under the old or new edition. Because towns update on different schedules, we confirm with each building department.

Can you help compare two parcels?

Yes. We run the same jurisdiction memo and conceptual estimate for each, covering code, floodplain, utilities and offsite costs, and give the owner a side by side view.
