Legacy yards along the South Platte need a different first step than a clean greenfield parcel: before we price a building in Sheridan, we price the ground. That means a records review, a conversation with the environmental consultant about what the reports mean for excavation and disposal, and a demolition plan that separates clean concrete from material that needs special handling. We sequence the work so the owner knows the cost of the site before committing to the shell.
A published brownfields summary describes the business park in Sheridan, bounded by U.S. 85, West Oxford Avenue, West Union Avenue and the South Platte River, as including auto salvage, a recycling center, a lumber yard, auto repair and light manufacturing uses. It also says the city planned Phase 1 and Phase 2 environmental assessments of the parcels through EPA's Targeted Brownfield Assessment program to estimate remediation costs. We do not interpret the findings for owners. We coordinate with their consultants and convert the findings into a construction scope.
Access is straightforward. U.S. 85 runs along Sheridan's eastern edge, U.S. 285 runs east to west through the city, and State Highway 88 (South Federal Boulevard) runs the length of the city from Englewood to Denver. That road network puts a Sheridan site within quick reach of the southwest metro and gives metals and heavy industry users, recyclers and yard operators a practical location for outdoor storage and heavy truck traffic.
Reading an environmental report as a contractor
A Phase 1 report identifies recognized environmental conditions. A Phase 2 report samples them. As the contractor we turn those findings into excavation limits, disposal categories, dewatering needs, vapor mitigation under new slabs and worker protection requirements. We want to read the reports before bidding, not after the contract is signed.
On a site next to a river, groundwater depth matters. We check it with the geotechnical borings, plan for dewatering permits where needed and design the foundations and slab to suit. If the consultant recommends a vapor barrier or a sub-slab system, it goes into the slab detail and the inspection plan.
Working on previously used industrial ground
Demolition and excavation on a legacy site call for a site-specific health and safety plan, air monitoring where the consultant requires it, decontamination for equipment, and trained workers for any regulated material. Our plan states who stops work, who calls the consultant and how stockpiles are managed.
We keep soil and debris segregated by category, track loads from excavation to disposal and keep the manifests in the turnover package. That documentation is useful when the owner sells, finances or insures the property later.
From demolition to a new shell
The sequence begins with industrial demolition, continues through slab and foundation removal with demolition and slab replacement, and then moves to grading and new construction. Recyclable concrete and steel are separated on site so the owner sees the credit in the bid, and underground tanks, sumps and old utilities are located and handled according to the consultant's direction.
New construction follows. For many Sheridan owners the right building is a pre-engineered metal building with a heavy-duty slab for equipment, a covered work bay and a large paved or graveled yard. We design the yard surface for the loads of loaders, trucks and stored material.
Sequencing reuse work
The critical path on a reuse project starts before construction. The environmental reports, any regulatory notifications, the demolition permit and the grading permit have to line up, and we track them on one schedule with named owners for each. While approvals run, we use the time to complete the survey, the geotechnical program and the utility locates.
Once approvals are in hand, demolition and excavation proceed in zones, so that cleared and tested areas can be released to foundation work while other zones are still being addressed. This overlap saves weeks, and it only works when the testing results are returned fast enough for the next crew to start.
Where brownfield budgets move
Budgets move with disposal volumes, dewatering, contaminated soil handling, unforeseen underground structures and the schedule effect of regulatory approvals. We price a base scope from the reports and carry named unit prices for the uncertain quantities, so the owner can see the exposure rather than a single lump contingency.
Another driver is the choice of building. A simple shell on a good pad costs less than a complex one on a site that needs deep foundations or vapor mitigation. We show the owner alternatives and the cost difference.
Neighbors and transit
Sheridan covers 2.29 square miles, borders Englewood and Denver, and has the Oxford-City of Sheridan RTD light rail station, whose only entrance is in Englewood. Work near the station and the rail line needs coordination with the transit agency, and we plan crane swings and deliveries so nothing crosses the right-of-way.
Many owners in Sheridan also look at Englewood and Littleton for expansion space, and we can compare the adopted code and access constraints in each.
Yards, laydown and site concrete
Industrial users in Sheridan often need yards before they need buildings. We build stabilized laydown yards with geotextile, base course and drainage, and we design the surface for the equipment that will use it. Where storage is open to rain, stormwater controls follow the site's discharge permit and the owner's own plan.
Fencing, gates and lighting are part of the same scope when the yard stores valuable material. We coordinate the electrical service, the lighting design and the fence to the same drawings.
Send the environmental reports with the survey
Send the survey, the environmental reports and the intended use. We will return a demolition, site and building scope with unit prices for the uncertain quantities.
Common Questions
Do you handle environmental cleanup?
We do not replace the owner's environmental consultant. We coordinate with them, convert their recommendations into an excavation and disposal plan, and build around the requirements. Cleanup that needs specialist licensed work is subcontracted to licensed firms under the consultant's direction.
What can I build quickly on a reused industrial site?
A yard with a simple building is often the fastest path, because it avoids deep foundations and extensive utilities. The environmental review and the permit still set the schedule, so we begin them first.
How do you handle groundwater near the river?
We check depth with borings, plan for dewatering where excavations reach water and design the foundation for the expected seasonal range. Dewatering discharge is permitted and monitored.
What documents should I give you when asking for a price?
Give us the survey, any Phase 1 or Phase 2 reports, the geotechnical report, existing building drawings and your intended use. If you do not have reports, we will list what we would need and the allowances we would carry without them.
Will the light rail line affect construction?
It can if the site borders the right-of-way. We coordinate crane swings, deliveries and fencing with the transit agency and avoid work that crosses the corridor. We also ask the agency about noise and vibration limits where work is close to the station.
