Hidden Creek 

Hall Irwin Corporation has partnered with LGI Homes to develop a community of 141 single family residences called Hidden Creek Subdivision, located in Fredrick, CO. Along with the widening of Ridgeway Boulevard, this project brings with it, a unique set of circumstances, including locating underground utilities and the various ways to work around them in the most cost effective way. Additionally, the scope of this project involves several key plans to insure over excavation of lots and streets, over lot grading of site, water and storm, sanitary install and dry utility sleeving are all recognized and developed accordingly.

In addition, concrete, asphalt and striping were completed in August 2020.


Phases 2 and 3 are slated to be completed in the 3rd quarter of 2022.

Buffalo Highlands

This is 165-lot residential development constructed for two home builders located near 96th avenue and Buckley Road in Commerce City, Colorado. 

​Over 800,000 yards of dirt containing lignite (combustible sedimentary rock) had to be moved in just 45 days on top of being asked to complete several of the lot sites six months ahead of schedule to accommodate their model homes. We were able to meet this request even though it was presented after the project had started. 

​Following site modifications of replacing lignite-contaminated soil with new fill dirt and compacting it to solid ground, the home builders had a prime location to build beautiful single-family homes.



Creekside’s 115 single-family residential lots in Thornton, Colorado are owned by the Woodbury Group. This project includes demolition, over-ex grading, utilities (sanitation, water and storm), concrete, asphalt, and signage/striping. There have been several interesting details along the way such as asbestos abatement and demolition of existing housing structures and a 300’ well.

Many offsite improvements include widening of Quebec St. & 128th Ave. 

The City of Thornton requested that we manage the new water line project down Quebec since we were already making improvements to the street for Creekside.



This was a multi-phase project completed in 2018 for one of our home builder clients, LGI Homes. We completed all site work and infrastructure for a 57-lot subdivision in phase 1. We were then asked to complete the site work for 52 lots in phase 2. The completed infrastructure included earthwork, utilities, water system and storm, curb and gutter, sub-evcation and paving. We also provided offsite improvements and the widening of Tipple Parkway. LGI was able to bring 109 new homes to the community of Frederick.

Hall-Irwin was chosen to provide the infrastructure and site development for KB Homes in the small, scenic town of Erie, Colorado. The Colliers Hill development is home to 98 duplex units and a community amenities center with 15 miles of trails, parks, and open space.

Westwood is another one of our multi-phased projects for one of our home builder clients, KB Homes. The 2-phase project will provide site work and infrastructure for a 167-lot subdivision in Thornton, Colorado. The completed infrastructure included earthwork, utilities, water system and storm, curb and gutter, sub-excavation, and paving. Offsite improvements include improvements to E. 152nd, Monaco and Holly Street. Signal Ditch improvements and 4,000 LF of offsite sanitary to an outfall location are also included in the offsite improvements. 



Cottonwood is a residential development project in Fort Lupton where we performed all the rough/final grading, installed all utilities, installed all of the concrete flatwork, and asphalt paved all roads. With this job, Hall-Irwin continues to have a great working relationship with LGI Homes.  The project is located next to the Coyote Creek Golf Course and Aims Community College. The one unique item on this project was off-site sanitary sewer work where we had to perform a bore underneath a bridge to tie in the sanitary system. This project was both started and completed in 2021.  


Kipling Townhomes

The owner for this project was Meritage homes whom we contracted with to deliver the land development work for their townhome development in Denver. We have performed many projects with Meritage on many occasions. This particular project was 8 acres of land which included an irrigation ditch running in the middle of the project. This caused the need to divert water around the site. We had to demo an existing home and some trees to begin working onsite.


Revere at Johnstown

Hall-Irwin began construction on this 320-lot, 77-acre subdivision in 2021, as the result of our relationship with Forestar Real Estate Group. There was a good deal of preparatory work to be done, including removing an irrigation ditch that ran through the center of the plot, and extending High Plains Blvd to meet with Co Rd 50 to the north. The owner self-performed the dirt work and dry utilities, leaving the rest to Hall-Irwin’s competent team. This project will have 45,000 linear feet or 8 and a half miles of new pipe installed. We met with the neighboring farmers to ensure lines of communication remained open and relationships were maintained, even contracting with one of them to build one of the necessary concrete structures. One difficulty our team had to navigate was the new book of specifications being written up by the Town of Johnstown, which was not published by the project’s start date. This necessitated extra communication and clarity between us, the engineers, and the Town, to ensure the subdivision would be built to the Town’s satisfaction as well as the owner’s.
