School and Campus Construction in the Boulder Valley

Boulder High School was among the buildings along Boulder Creek that were seriously damaged when the creek ran past 5,000 cubic feet per second in September 2013, against a normal flow of about 150 to 200. A school is a building that serves a neighborhood for many decades, so where it sits relative to water is a design question that outlasts any bond cycle. We bring that long view to every school and campus project: a site that drains, a structure that tolerates the foothills wind and snow, and finishes that survive thousands of students a day.

Education work here ranges from a K-12 classroom addition to a laboratory or residence hall on a university campus. The owners are different, a school district with a voter-approved bond or a university with a campus design standard, but the constraints are shared: a fixed academic calendar, a public process and a community that watches the site. The work we do is arranged around that calendar.

Two kinds of owners, two kinds of process

School districts are among the largest employers in the metro, and for education institutions the capital program is a public matter. Boulder Valley School District lists 3,832 employees in the city's 2022 report, and St. Vrain Valley Schools, with 3,543 employees in Longmont's 2020 report, is the top employer in Longmont. Their capital programs are public, with board meetings, community input and a procurement process that sets how contractors are selected. We follow each district's rules and plan to participate in the process, not to bypass it.

The University of Colorado Boulder is a different animal. Its main campus covers 786 acres, East Campus lies about a quarter mile away with athletic fields and research buildings, and Williams Village is about 1.5 miles from the main campus. The university has its own design standards, with campus buildings following a Tuscan Vernacular Revival style that uses Front Range sandstone, limestone trim and red-orange tile roofs on fifteen buildings from 1921 to 1939. Anyone building on or next to the campus area should expect that visual language to carry weight in design review.

Building to the academic calendar

School schedules start with the date students arrive. A new building or addition that is not ready for the first day of the fall term costs the district real money in portable classrooms or displaced classes, and most education work is planned so that the heaviest disruption falls in the summer. We build a schedule from that date backward, identifying what must be done before the end of the school year, what can wait for summer, and what can proceed while classes are in session.

For campus work, the calendar is similar but broader: move-in weeks, game days, commencement and research cycles all affect what can happen where. We hold early coordination meetings with campus facilities, and we agree on laydown areas, haul routes and noise windows in writing. Long-lead items such as laboratory casework, fume hoods, switchgear and roofing materials are ordered during design, so the summer window is spent installing, not waiting. The education facility construction process uses the same logic.

Floodplains, editions and the permitting reality

Where a school touches a creek corridor, the City of Boulder requires a Floodplain Development Permit for any building with part of its structure in the 100-year floodplain, including overhangs, gutters, footings and decks. Many school sites include playing fields and parking in the floodplain and the building itself on higher ground, so the permit conversation often concerns site improvements rather than the building. We start that conversation early.

Editions vary. The City of Boulder adopted the 2024 International Building Codes effective August 1, 2025, with the 2024 City of Boulder Energy Conservation Code effective December 1, 2024. Louisville was also on 2024 as of December 6, 2025, while Lafayette and Longmont were on 2021 with updates planned, and Erie was weighing a move. Colorado law, under HB22-1362, requires any jurisdiction that updates its code to adopt an energy code at least as strong as the 2021 IECC. Districts that build in several towns should expect different requirements in each, and we keep a current table.

Classrooms, labs, gyms and the underground

A school or campus project is a collection of building types. Classrooms are the base, and they need acoustics, daylight, ventilation and technology infrastructure. Gyms and auditoriums have long spans and tall volumes. Laboratories need fume hood exhaust, specialty gases, vibration control and deep utility chases. Kitchens, locker rooms and labs add plumbing, and a library or media center adds data and power.

On campuses, parking and utilities often go underground. The Center for Community at CU Boulder, a 323,000 square foot building completed in September 2010 for $84.4 million, includes a 140,000 square foot underground parking structure (we cover the type separately under parking structures), which gives a sense of how much earthwork and structure can sit below a student building. Digging below a campus brings questions about groundwater, utility conflicts and existing foundations. We scope that work carefully, with a concrete foundation plan that accounts for soils and frost depth, and with early coordination with campus utility managers.

Work we keep close on school sites

Schools are tight sites, with limited laydown space and a safety imperative around children. Scheduling and supervising the concrete, framing and general conditions trade partners directly lets us control the people on site, their sequence and their conduct. We prefer to use a small number of crews who understand the site's rules, who wear identification and who know where fenced areas and delivery routes are.

Fencing, signage and daily communication with the principal's office or the campus facilities manager are standard, as are background checks where the district requires them. A project that is calm to its neighbors is usually one that planned its logistics well. Similar planning applies to municipal buildings such as recreation and community centers, which often share site conditions and public processes with schools.

Questions Owners Ask

How do you build a school while students are on site?

We separate construction from student areas with fencing, dedicated entrances and haul routes, and we do noisy or disruptive work when classes are not in session. We hold regular meetings with the principal or facilities manager and post a short look-ahead. Utility shutdowns are scheduled in advance and confirmed in writing.

Does a school in the floodplain need special permits?

In the City of Boulder, any building with part of its structure in the 100-year floodplain needs a Floodplain Development Permit, and the rule reaches footings and overhangs. Many school sites keep buildings on higher ground and put fields in the floodplain. We check the mapping before the site plan is fixed.

Can summer be enough time for a major renovation?

For a focused scope, yes, if procurement is done before school lets out. Casework, roofing, mechanical units and electrical gear must be ordered during design. For larger projects, we phase over more than one summer, with interim occupancy plans.

Which building code will a school follow?

The edition adopted by the jurisdiction. Boulder and Louisville were on 2024 in the tracker we reviewed, while Lafayette, Longmont and Erie were on 2021 with updates under consideration. State law requires an updated code to include an energy code at least as strong as the 2021 IECC, so we confirm both with the department.

Do campus buildings need to match the historic style?

On the CU Boulder campus, many buildings follow the Tuscan Vernacular Revival style, with sandstone and tile roofs. New buildings are reviewed with that heritage in mind, though the university sets its own design standards. Our estimates carry material allowances that reflect the masonry and roofing specified.
