Featured Projects

The staff from Golden Triangle was very communicative and supportive of the NHS community and the daily business of providing instruction at the highest level. …They understand the value providing a top notch construction experience while allowing my school to focus on the job of educating students. I heartily recommend GTC for any additional construction jobs that may occur in our school district.

Location: Boulder, Colorado

Description:This middle school received a 21st Century Learning Design renovation and addition, totaling just under 39,000 square feet. Its scheduling presented a unique challenge, due to the fact that there was no available space to phase the renovation-portion of this project, while the students were in-session. To solve this dilemma, GTC began the 15,260sf addition in January. Then, as soon as school let out for the summer, we halted the addition and pushed all of our resources into expediting the 23,650sf renovation, which we completed by August 20, just in time for classes to resume. At that point we re-allocated our crews back to the addition. We achieved completion of the addition by October 28 – two months earlier than originally estimated.

Mapelton school district - welby community school addition

Location: Denver, Colorado

Description: A 20,000 sf addition and 35,000 sf renovation to Welby Community School for the Mapleton Public School District. The existing building was constructed in the early 1960s. It is a midcentury modern building with a low sloping roof bearing on brick masonry walls. The building had undergone various remodels throughout the years. The addition is an estimated 21,650 sf and was constructed in phases to accommodate the school calendar. The entire rest of the existing school was renovated over the summer, including a new, upgraded play structure outdoors. The addition gives the PK-6 school a gym, a new entry and admin area, seven new classrooms, and a music room. The added classrooms support Additional Kindergarten and Special Education capacity. The addition also increases security and line-of-sight at the front entrance / administration areas, creates dedicated art and music classrooms, and separates the library from the cafeteria. The site work and renovation were completed first, and were ready for the students' return in Fall 2017. The second phase, consisting of the new addition, was completed by Spring 2018.



Loveland Classical School

Location: Loveland, Colorado

Description: A new 53,200 sf grade 6-12 charter school on a 12 acre site. The 2-story building is constructed of precast concrete exterior envelope, slab-on-grade and spread footing foundation. The interior of the facility includes classrooms, administration, dining commons and learning commons. The building is Type IIB Construction and is fully sprinklered. Site improvements included utilities, site paving, grading and landscaping. Several add alternates are included in the scope including a gymnasium addition of 7,000 SF, a brick masonry colonnade along the south elevation and several interior finish upgrades.Midway through design, the Owner was faced with unfortunate funding challenges that required re-programming in order to work within the new funding limits. This meant that design had to, in a large part, start over. We were able to work with the Owner and Design team to:• Revise building structural systems to would allow for a shorter construction schedule to counteract design delays• Find savings opportunities through efficient space planning and use of materials to work within budget constraints• Provide design and details that allowed for future phases to be more easily accommodated if additional funding was available at a later date.The owner was later able to procure funds for a gymnasium “addition” halfway through the project. Since we had already planned for this addition in the design and details, this was able to be added to the current construction without delaying the completion date
