Overview: CSA-Compliant Confined Space Surveys Services for Industry & Infrastructure

Ven‑Tech Subsea provides specialized Confined Space Survey Services to support engineering, regulatory, and operational needs across the utility, municipal, industrial, and energy sectors. We conduct accurate internal surveys of tanks, vaults, pipelines, culverts, reservoirs, digesters, and other confined spaces using advanced robotic tools, optical metrology, and CSA-compliant human entry teams when necessary.

Whether your goal is as-built verification, defect mapping, asset lifecycle documentation, or engineering design, our team ensures that every confined space survey meets WorkSafeBC Part 9, CSA Z1006, and industry-specific standards. All work is performed with a strict focus on safety, accuracy, and zero-compromise execution.

What Is a Confined Space Survey Services?

A confined space survey is a structured process of measuring, documenting, and mapping the internal features of a hazardous or restricted-access environment. Unlike a general inspection, a confined space survey captures geometric dimensions, structural features, internal components, defect locations, and other engineering-relevant data.

Ven‑Tech Subsea conducts confined space surveys using:

  • ROVs (remotely operated vehicles) with video and sonar

  • Pipe crawlers with high-resolution imaging

  • Laser scanning or structured light 3D mapping

  • Manual measurement and layout via CSA-compliant entry teams

  • HD pole cameras with measurement overlays

All survey activities are planned in accordance with CSA Z1006: Management of Work in Confined Spaces, including risk assessments, entry permitting, air monitoring, standby rescue, and emergency planning.

Where We Perform Confined Space Survey Services

Ven‑Tech Subsea performs confined space surveys in a variety of applications:

  • Potable water reservoirs and clearwells

  • Storm and sanitary pipelines (box, barrel, or circular)

  • Chemical and process tanks

  • Hydroelectric intakes and surge tanks

  • Wastewater treatment facilities (clarifiers, digesters, etc.)

  • Fire suppression reservoirs (NFPA 25)

  • Industrial ducts, bins, and silos

  • Manholes, valve chambers, and lift stations

  • Pulp and paper mill assets

We tailor each survey to the environment, using the least invasive and safest method possible—whether remote, visual, or certified entry.

Methods of Survey Execution

✅ Remote Robotic Survey (No Entry Required)

  • ROVs for submerged or partially flooded assets

  • Pipe crawlers with inclinometers and distance encoders

  • HD PTZ pole cameras for overhead vaults and tanks

  • Structured light mapping and sonar overlays

This method avoids confined space entry and reduces downtime and risk.

✅ Laser-Based 3D Surveying

  • 360° LiDAR or laser scanning from within the space

  • Generates point clouds, 3D mesh, and CAD-ready files

  • Ideal for retrofit design, structural analysis, or modeling

✅ CSA-Compliant Manual Survey

  • Certified entry technicians with gas monitors, PPE, tripod/fall arrest systems

  • Tape, laser, and total station measurements

  • Used where geometry is too complex for robotic access

  • Detailed entry procedures, air monitoring, and rescue protocols included

Deliverables: What You Receive

All confined space surveys are delivered with a full documentation package tailored to engineers, project managers, and regulatory authorities:

  • 📐 As-built internal layout drawings (AutoCAD, PDF)

  • 🧭 Geometric dimensions, depths, diameters, and wall thicknesses

  • 🧠 ATHENA-enhanced defect tagging and risk categorization

  • 🗂️ 3D models, point clouds, or orthomosaics (if applicable)

  • 📸 Annotated HD video and still images

  • 📑 Survey report, hazard log, and safety summary

  • 🔍 Recommendations for repair, cleaning, or inspection

  • ✅ Compliance checklists (CSA, WorkSafeBC, NFPA, AWWA)

If required, we integrate this data with your existing GIS or asset management system for future lifecycle tracking.

Safety & Certification First

At Ven‑Tech Subsea, safety is non-negotiable. Every confined space survey is planned and executed under a CSA and WorkSafeBC-certified safety management system, including:

  • ✅ CSA Z1006: Management of Work in Confined Spaces

  • ✅ WorkSafeBC Part 9 and equivalent provincial legislation

  • ✅ ISNetworld, Avetta, Cognibox, Alcumus CSA certified

  • ✅ BCCSA COR Certified Contractor

  • ✅ $5M Commercial Liability Insurance & WCB Clearance

  • ✅ Full confined space rescue team & emergency gear on site

  • ✅ Gas detection, SCBA/SABA, ventilation, and entry permits in place

Each project includes a Hazard Assessment, Entry Procedure, Rescue Plan, and site-specific safety documentation. We also provide confined space inspections (learn more here) when visual-only data is sufficient.
