The BC One Call gap in Surrey

BC 1 Call marks public utilities to your property line — always request it, it's free. But every service inside the line is private and stays unmarked. That gap is where most utility strikes happen, and liability lands on whoever dug. This service closes the gap.

Locating conditions in Surrey

Ground: Surrey sits on till uplands across Whalley and Fleetwood, Serpentine/Nicomekl floodplain silts through the lowlands. Upland till scans 2–3 m reliably; the Serpentine and Nicomekl floodplains run wet and silty, so deep targets there lean on EM pairing and tighter grids.

What's buried here: BC's fastest-growing city — City Centre highrise slabs, vast 1980s–2000s subdivisions, and farm parcels with undocumented private services.

Common subsurface utility engineering (sue) work in Surrey

  • Pre-construction locates on infill developments
  • Private utility mapping on agricultural parcels
  • Underground service leak tracing in 1980s subdivisions
  • Slab scanning across City Centre tower construction
  • Municipal and institutional capital projects
  • Roadway and utility corridor design
  • Risk allocation on major excavations

How the Surrey locate works

  1. 1

    QL-D records research

    All available utility records compiled and georeferenced — the baseline layer every project starts from.

  2. 2

    QL-C site correlation

    Surface features — valves, manholes, pedestals — surveyed and reconciled with the records layer.

  3. 3

    QL-B geophysics

    GPR + EM designate utility positions across the corridor; output is survey-grade horizontal mapping.

  4. 4

    QL-A verification

    Critical conflicts are daylighted (vacuum excavation by partner crews) and surveyed in three dimensions — certainty where the design needs it.

CSA/APWA uniform colour code. Standard practice: mechanical digging stays 60 cm clear of any mark; the last hand-width is exposed by hand or hydrovac.

Surrey questions, answered

Why specify SUE instead of a standard locate?

Standard locates serve excavation safety; SUE serves design. The ASCE 38 framework attaches a defined quality level to every utility shown, letting engineers allocate risk contractually and decide precisely where to pay for QL-A certainty. On capital projects, SUE routinely returns multiples of its cost in avoided redesigns and claims.

Do you perform the QL-A vacuum excavation yourselves?

We scope and supervise QL-A test holes and survey the exposed utilities; the daylighting itself is performed by partnered hydrovac crews. One contract, one deliverable, with each party doing what they're equipped for.

What do your SUE deliverables look like?

Sealed-format CAD with utilities attributed by quality level, a basis-of-investigation report, and test-hole logs for any QL-A points — the package engineers of record expect to reference in contract documents.

Is SUE overkill for a small commercial site?

Sometimes — and we'll say so. Many sites are served perfectly by QL-B mapping without the SUE formalism. The free consult sorts which investigation level your project and its risk profile actually need.

Does BC One Call cover my Surrey property?

Only partially. BC 1 Call marks registered public utilities up to your property line — free, and you should always use it. Everything inside the line is private and unmarked: irrigation, gas runs to outbuildings, landscape lighting, old septic, abandoned services. Surrey's stock — bC's fastest-growing city — City Centre highrise slabs, vast 1980s–2000s subdivisions, and farm parcels with undocumented private services. — is exactly where those private surprises accumulate. Private locating closes that gap before you dig.

How do Surrey ground conditions affect the locate?

Surrey sits on till uplands across Whalley and Fleetwood, Serpentine/Nicomekl floodplain silts through the lowlands. Upland till scans 2–3 m reliably; the Serpentine and Nicomekl floodplains run wet and silty, so deep targets there lean on EM pairing and tighter grids. Where local conditions limit one technology, the survey leans on the others — EM tracing, sonde work, and acoustic methods — so the locate objective is met regardless of soil.

How quickly can you do a locate in Surrey?

Surrey is inside our standing Metro Vancouver coverage — typical scheduling is 24–72 hours, with same-day service often possible during business hours (Mon–Sat, 8am–6pm Pacific). Pricing follows our province-wide structure with no regional premium; the free phone consult produces a firm number in about five minutes: 604-239-9934.
