# School and Institutional Underground Utilities in Denver

Campus underground work is governed by a calendar and by who is on site. Denver Sewer and Water performs sewer, water, and fire line work for schools and institutional facilities with phased scheduling, secured excavation, and documentation the facilities office can file.

- Campus sewer, water, and fire service lines.
- Break and summer window scheduling.
- Fully secured and fenced excavation areas.
- Phased work across multiple buildings.
- Denver metro schools, campuses, and public facilities.

## Facilities Directors Are Scheduling Against a Fixed Calendar

On a campus the constraint is not usually money, it is the window. Work that can happen over a summer or a scheduled break is straightforward. Work that has to happen while a building is occupied requires a completely different plan.

Institutional sites also age in layers. Buildings added across decades sit on utility runs of different vintages, and record drawings frequently do not match what is actually buried, particularly where a later addition crossed an older line.

Safety expectations are stricter than on a commercial site. An open excavation anywhere near students or patients has to be secured to a standard that assumes people will approach it, and that assumption shapes the site plan.

- Sewer lateral replacement between buildings and the main.
- Domestic water service repair and upsizing during renovations.
- Fire service line installation for building additions.
- Storm and area drainage across fields, courtyards, and lots.
- Locating and mapping utilities where record drawings are incomplete.

## Planning Around Occupancy and the Calendar

Scoping starts with the academic or operating calendar. We identify what fits inside a break, what must be phased across multiple windows, and what genuinely cannot wait, then plan each differently.

Where drawings are unreliable, we locate and verify before excavating. Hydro excavation is used to expose unknown crossings without risking a live utility, which on a campus can mean cutting service to buildings that are not part of the project.

Every open excavation is fenced, covered, and secured outside working hours, and pedestrian routing is planned so people walking the site are directed away rather than expected to notice.

- Excavation fenced and secured at the end of every shift.
- Pedestrian routes rerouted, not just signed.
- Utility crossings verified before digging, not assumed.
- Work phased so no building loses service unannounced.
- As-built information returned to the facilities office.

## How Institutional Projects Run

1. **Calendar and Scope Alignment** The scope is divided against the available windows so each phase can finish inside its window rather than spilling into occupancy.
2. **Verify What Is Buried** Locating and hydro excavation confirm the actual utility layout before trenching, because record drawings on older campuses are often incomplete.
3. **Secure and Execute** The work area is fenced and routed around, and the phase runs with service interruptions confined to the agreed times.
4. **Document and Hand Back** The completed work is inspected, restored, and documented with locations so the facilities office has an accurate record going forward.

## What Drives Institutional Project Cost

Phasing drives cost more than pipe on most campus projects. Three separate mobilizations across three breaks cost more than one continuous run, and sometimes that tradeoff is still the right call.

Unknown utilities add exposure time. Where drawings are poor, careful verification is an investment that costs far less than cutting an unmarked line serving an occupied building.

Restoration standards on fields, courtyards, and hardscape vary widely and are a significant part of the total on visible areas.

## Frequently asked questions

**Can the work be done while school is in session?**

Some of it. Exterior runs away from pedestrian areas can proceed with secured excavation and rerouting. Work adjacent to entrances, play areas, or occupied buildings is generally scheduled into breaks, and we will tell you plainly which category your project falls into.

**What if our utility drawings are wrong?**

We assume they might be. Locating and hydro excavation verify actual positions before trenching begins, which prevents the far more expensive outcome of cutting a live line serving a building that is not part of the project.

**How is an open excavation kept safe on a campus?**

Excavations are fenced, plated or covered, and secured at the end of every shift, and pedestrian routes are physically redirected rather than signed. The plan assumes people will approach the area.

**Do you provide records for our facilities office?**

Yes. Locations, depths, materials installed, and camera documentation are provided so the next project on that campus starts with better information than this one did.
