RecordedOverview
The scenario was familiar to everyone on the call: a road reconstruction already in construction, a duct bank nobody's drawings showed, and a contractor's delay claim on the city manager's desk. The panel worked backward from that moment to the decisions that could have prevented it.
They agreed on one point early. The utility problem wasn't discovered in construction. It was created in planning, when the project was budgeted on records nobody had checked. Every unknown carried past schematic design becomes a cost the city pays later, at the highest possible price.
“The change order was written in planning. We just didn't read it until construction.”
The less you know early, the more you pay late.
Key Takeaways
- 01
Most utility change orders trace back to an information gap in planning, not a failure in construction.
- 02
811 is not a complete inventory. Confirm which municipal systems are registered.
- 03
Decide a target ASCE 38 quality level per project segment before scoping the fee.
- 04
Field locating before design costs far less than discovery during construction. Do it before the budget is set.
- 05
GPR/EM designation shows what's there; a stamped ASCE 38 deliverable is a separate engineering step.
- 06
Move utility coordination from 60% design to schematic.
- 07
Put utility risk in the contingency line, sized to what you actually know.
- 08
Track change orders by cause so the next budget learns from this one.
The Scenario
Case file · Event 01
- City
- [Mid-size city, ~120,000 residents]
- Project
- 1.2-mile arterial reconstruction with new storm drainage and sidewalks · [$14M]
- What existed
- 811 tickets, water/sewer GIS, 1970s and 1990s as-builts, no telecom records
- Constraint
- Construction season window; two schools on the corridor
- The decision
- “How should this project have been scoped, and what does the city change before the next one?”
Expert Positions
[City Engineer]
“Why did the budget miss it?”
The project was budgeted from GIS and 811 tickets. No records research phase was funded, so the telecom duct bank never appeared in any estimate. [Summary placeholder.]
“[Pull quote placeholder]”
[SUE Engineer]
“What should the investigation have looked like?”
Match the quality level to the risk in each segment rather than applying one level to the whole corridor. [Summary placeholder.]
| Level | What it involves | When it's worth it |
|---|---|---|
| D | Records research | Every project, at concept |
| C | Records + surveyed surface features | Most corridor projects, at schematic |
| B | Field designation (EM, GPR) | Where conflicts are likely |
| A | Exposed and surveyed (test holes) | Critical crossings and tight designs |
Level: D
What it involves: Records research
When it's worth it: Every project, at concept
Level: C
What it involves: Records + surveyed surface features
When it's worth it: Most corridor projects, at schematic
Level: B
What it involves: Field designation (EM, GPR)
When it's worth it: Where conflicts are likely
Level: A
What it involves: Exposed and surveyed (test holes)
When it's worth it: Critical crossings and tight designs

[GPRS Project Manager]
Vendor / practitioner-reported“What can a city know on day one?”
Field locating with GPR and EM designation marks what is actually in the ground, including private and unrecorded lines, and delivers it as a GIS-ready SiteMap the city keeps. A starting point for engineering review. Vendor-described.

The Complication
Mid-session, the moderator revealed: “The duct bank belongs to a telecom provider that isn't a member of the local 811 center, and their records show it on the other side of the street.”
The panel's recommendations shifted. Records alone aren't enough when they place a line on the wrong side of the street. Identifying every owner in the corridor became a first step, not a courtesy. And targeted spot-checks before design moved from optional to essential wherever records and reality might disagree.
The Decision Path
If this were our city:
- 1
Fund a records-research step at concept on every project over [$X].
- 2
Set quality levels by segment at schematic, and budget field verification where conflicts cluster.
- 3
Track utility change orders by cause and report them to council annually.

Field Guide
Before you budget: utility risk checklist
0/10Where field locating and SiteMap fit
| Phase | Use | Value |
|---|---|---|
| Feasibility | Records research plus targeted GPR/EM locating on high-risk segments | Defensible early estimates |
| Schematic | Existing-conditions map delivered in SiteMap | Target field work where it matters |
| Field planning | Direct test-hole crews to verified designations | Fewer wasted mobilizations |
| Design | Cross-check against QL-B/QL-A results | Catch gaps before bid |
| Construction | Reference for crews and inspectors | Context, not a substitute for locates |

Questions to ask any locating provider
- Which methods (GPR, EM, CCTV) were used on each line?
- Are private and abandoned lines included?
- Who certifies the field crew?
- What export formats fit our GIS and CAD?
- How are field corrections incorporated?
- What should we still verify in the field?
Crawl
Field-locate one upcoming project before design; compare it with the old process.
Walk
Make it a standard concept-phase step; track change orders by cause.
Run
Build quality-level targets and utility contingency into every capital project.

[Panel reaction placeholder] The panel noted that the room split closely between budgeting from existing records and a locate-first approach, and discussed what it would take to make records research a default step.
