Safety systems are only as good as the records behind them.
Every locate response, emergency isolation, and field crew dispatch in a gas utility runs on spatial data. When that data is incomplete, outdated, or ungoverned — the safety system built on top of it carries the same flaw. We fix the records layer that safety depends on, using the same programs a leading Canadian gas distribution operator developed over twenty years of TSSA oversight and CGA best-practice compliance.
Three safety failures with the same root cause.
Third-party damage from locate failure.
A contractor excavates based on a locate response. The locate was issued from a GIS that hasn't reflected the last three construction projects. The pipe is 40 centimetres from where the mark says it is. This is how gas mains get struck — not from reckless excavation, but from records that nobody was accountable for maintaining. In Canada, this failure mode drove the entire One Call regulatory framework. Mexico is building that framework now.
Regulatory non-compliance under audit.
ASEA and CRE require pipeline operators to demonstrate that their safety-critical records are Traceable, Verifiable, and Complete. MAOP documentation, pressure test records, material specifications — every one of these must be reconstructible from source documents. When records have been migrated between systems, stored on paper, or maintained inconsistently over decades, TVC compliance becomes an audit liability. The fine is secondary. The operating restriction is not.
Field crew exposure from missing spatial data.
A crew working alone near a high-pressure main needs to know what's buried within their work zone — not approximately, not from memory, not from a map their supervisor isn't sure about. Work-alone programs and field check-in systems only function if the spatial data they draw from is accurate. A crew member relying on incorrect infrastructure data isn't making a mistake. The system failed them before they picked up a shovel.
Four programs. One integrated safety layer.
Locate & Damage Prevention
End-to-end locate program design using the Canadian one-call framework — adapted to Mexican regulatory requirements under NOM-007-ASEA and CRE damage prevention obligations. Every locate workflow, ticket management process, response SLA, and post-incident review protocol built from the ground up, or rebuilt where existing programs have gaps.
One Call workflow design
Intake, assignment, response, and close-out workflows modeled on CGA Best Practice 2-89 and adapted to SICT/CRE notification requirements. Ticket management integrated with GIS so locators work from accurate, current network data.
Locate quality audits
Structured review of locate accuracy against actual infrastructure position. Where GIS doesn't match ground truth, findings feed directly into a records remediation program — so the next locate is better than the last.
Damage prevention training
In-Spanish training for locate technicians, field supervisors, and third-party contractors. Covers excavation tolerance zones, positive response obligations, damage reporting, and near-miss documentation.
Post-incident review program
Structured root-cause analysis for locate failures and near-misses. Findings documented, corrective actions tracked, and GIS or workflow deficiencies addressed before the next incident occurs.
Emergency Response GIS
When a gas main ruptures or a pressure regulator fails, the control room needs one thing: a map they can trust under pressure. We configure GIS for emergency operations — isolation valve networks, pressure zone mapping, emergency operating procedure integration — so the response is measured in minutes, not hours.
Isolation valve network modeling
Accurate spatial representation of every isolation valve, its operating status, last-exercised date, and the network segment it controls. Topology validated so the "closest upstream valve" query returns a correct answer — not the nearest valve in the database.
Pressure zone mapping
Spatial delineation of operating pressure zones, interconnections, and isolation boundaries. Essential for emergency dispatch and for regulatory reporting of MAOP compliance across the network.
EOP-GIS integration
Emergency operating procedures linked to spatial features — so when an operator triggers an EOP, the relevant map view, valve sequence, and isolation steps are surfaced in context, not buried in a binder.
Control room map accuracy program
A recurring QA cycle that validates emergency-critical GIS layers against field reality. Prioritizes the network segments and facilities most likely to require emergency response — not a uniform audit of the entire network.
TVC Records & MAOP Compliance
Traceable, Verifiable, Complete records are the regulatory standard that determines whether a pipeline operator can defend its Maximum Allowable Operating Pressure under audit. We assess TVC compliance, identify documentation gaps, and design the remediation programs that close them — before the regulator finds them first.
TVC compliance assessment
Structured review of safety-critical records against TVC criteria: are records traceable to source documents, verifiable through independent means, and complete for the required scope? Findings prioritized by regulatory risk and consequence of failure.
MAOP documentation remediation
Pressure test records, material specifications, design documentation — reconstructed, organized, and linked spatially so every pipe segment can demonstrate its MAOP basis from source evidence. Where documentation cannot be reconstructed, remediation options are clearly defined.
Records digitization for safety-critical assets
Paper pressure test records, construction drawings, and material certifications converted into structured, spatially linked digital records. Priority given to assets in high-consequence areas, high-pressure transmission, and facilities subject to ASEA integrity verification.
Regulatory audit preparation
Pre-audit records review, gap identification, and documentation package preparation for ASEA or CRE safety compliance audits. We find the gaps before the auditors do — and provide a defensible remediation plan for those that can't be resolved before the audit date.
Field Worker Safety Systems
Gas utility field workers operate in hazardous environments — often alone, often near high-pressure infrastructure, often in areas where the buried network is not fully mapped. We design and deploy the spatial systems that give field crews, dispatchers, and supervisors reliable awareness of who is where, what is nearby, and what the protocol is when something goes wrong.
Work-alone programs
Check-in interval design, escalation procedures, supervisor notification workflows, and the mobile GIS integration that makes check-in frictionless for field crews. Built around real crew workflows — not a compliance exercise that gets ignored after the first week.
Crew location monitoring
Real-time crew location integrated with network infrastructure maps — so dispatch knows not just where a crew is, but what infrastructure they're near, what operating pressure they're working adjacent to, and what the emergency response protocol is for that location.
Hazard proximity awareness
Mobile GIS configuration that surfaces relevant hazard information — high-pressure mains, cathodic protection zones, pressure regulation stations, known encroachments — as crew members enter a work area. Dependent on GIS accuracy; always paired with a records quality assessment.
Safety form standardization
Survey123 safety forms for pre-task hazard assessment, gas detection readings, PPE verification, and incident reporting — standardized, bilingual, and integrated with work order management so safety documentation and work records share the same spatial context.
Canadian standards. Mexican regulatory context.
Canada's pipeline safety regulatory framework is among the most demanding in the world — developed under sustained pressure from TSSA, CER, OEB, and provincial occupational health and safety legislation. The programs below were built inside that framework. Each has a direct analog in Mexico's emerging regulatory structure. We adapt the substance; the rigor transfers intact.
CSA Z247 — Damage Prevention
The national standard for excavation safety and buried infrastructure damage prevention. Defines locate response requirements, tolerance zones, and notification obligations for all pipeline operators.
NOM-007-ASEA / CRE Damage Prevention
Pipeline safety and third-party damage prevention requirements under ASEA oversight. Less mature than CSA Z247 but directionally consistent — and tightening.
CGA Best Practice 2-89 — Locate Quality
Canadian Common Ground Alliance standard for locate quality management — covering ticket response, field marking, and quality metrics that determine whether a locate program is defensible.
Emerging SICT / CRE Framework
Mexico is formalizing its one-call and locate quality framework. Operators who build CGA-equivalent programs now will be ahead of the regulatory curve — not scrambling to comply after an incident.
TSSA TVC Requirements
Ontario's Technical Standards and Safety Authority requirement for Traceable, Verifiable, Complete records for all safety-critical pipeline documentation. Developed under sustained regulatory enforcement.
ASEA Integrity Verification
ASEA pipeline integrity rules require operators to demonstrate records traceability for MAOP basis and material certification. The TVC framework is the most rigorous available model for compliance.
OHS Work Alone Regulations
Provincial occupational health and safety requirements for lone workers in hazardous environments — including check-in procedures, escalation timelines, and supervisor accountability.
NOM-031-STPS / NOM-031-ASEA
Mexican safety norms for construction and maintenance work near pipelines and in hazardous facilities. Field worker safety system design is calibrated to these requirements.
