3D Models and Digital Twins
Transform complex utility and infrastructure data into accurate, defensible 3D models that support better planning, design coordination, risk management, and decision-making.
Railways
Rail systems—freight, passenger, and commuter—operate on long, often aging corridors with limited utility or as-built documentation. Rail operators require high reliability data collection, safety qualified staff, and strict compliance with railroad access procedures.
What We Do
Kiwa supports maintenance, expansion, and system upgrades through:
- Surveying, SUE, and right-of-way utility investigations
- Utility relocation design and coordination with rail operators
- Track, corridor, and structural assessments
- Specialized access planning and safety certified field teams
- Design support for stations, crossings, and adjacent developments
Why This Matters
Railway incidents or asset failures can have serious safety and operational consequences. Independent oversight strengthens safety management and long-term resilience.
How Kiwa Delivers Value
Kiwa delivers rail specific value by:
- Deploying rail-trained, safety qualified field staff who meet operator access and protection requirements
- Providing SUE and surveying tailored for long, legacy corridors with limited documentation
- Reducing service disruptions through coordinated scheduling with rail control and operations teams
- Supporting infrastructure expansion with engineering analysis for bridges, railbeds, stations, and crossings
- Strengthening quality and compliance via construction engineering and inspection, materials testing, quality management and QA/QC oversight
- Lowering construction risk by accurately identifying underground assets and potential conflicts before work begins
With our specialized expertise, rail owners and contractors gain reliable data to maintain safety and optimize system upgrades.

Our services include
Utility Mapping (ASCE 38 not requested)
Accurate utility data tailored to your project needs, helping you understand existing infrastructure and manage risk without the scope of a full SUE investigation.
Underground Storage Tank Investigations
Identify potential underground storage tanks with confidence using non-invasive Ground Penetrating Radar (GPR) investigations that help reduce uncertainty and support informed property decisions.
Inflow and Infiltration Investigations
Identify and confirm the location of groundwater entering sewer systems with inflow and infiltration investigations that support data-driven rehabilitation and asset management decisions.
Tree Root Mapping
Advanced geophysics helps identify and map shallow tree root systems, supporting informed tree management decisions and reducing conflicts with planned construction or existing infrastructure.
Marker Ball Installations
Simplify future utility locating and verification by installing marker balls on difficult-to-detect underground infrastructure.
Private Locates
Identify and mark privately owned underground utilities before excavation, construction, or site development activities begin.
Cross-bore Prevention and Verification
Protect critical underground infrastructure and reduce HDD-related risk with CCTV-based cross-bore prevention and verification services from Kiwa T2.
Sewer Mapping
Accurate sewer mapping that helps owners, engineers, and project teams understand the location and orientation of non-linear sewer infrastructure.
LiDAR and Mobile Mapping
Capture accurate, detailed, and comprehensive spatial data with LiDAR and mobile mapping solutions that support planning, design, construction, asset management, and infrastructure decision-making.
As Built Documentation (ASCE 75/CSA S250)
Professional support for accurate as-built documentation, ensuring compliance with ASCE 75 or CSA S250 standards for engineering and construction projects.
Tracer Wire Verification
Verify tracer wire continuity and connectivity to help support accurate future locating of non-conductive underground utilities.
Subsurface Utility Engineering (SUE) Investigations (ASCE 38)
Professional investigation and analysis of above-ground and underground utilities to provide reliable utility information following the ASCE 38 that supports safer, more informed project planning and design.
Sewer Pipe Condition Assessment (PACP)
Accurate CCTV sewer inspections conducted to NASSCO PACP standards to help owners understand asset condition, prioritize maintenance, and support informed infrastructure decisions.
Public Locate Project Management
Comprehensive management of public utility locate projects, ensuring safe excavation, regulatory compliance, and efficient project delivery.
Utility Coordination
Utility impacts and relocations present significant risks to infrastructure project delays. T2 Utility Engineers Utility Coordination professionals develop a managed approach to identify and guide the complex utility conflict resolution process, working c...
Sewer Lateral Condition Assessment (LACP)
NASSCO-compliant sewer lateral condition assessments to help asset owners understand the condition, performance, and rehabilitation needs of service lateral infrastructure.
Visual Verification of Utilities (Hydro-Vac Excavation)
Direct observation and documentation of exposed utilities to confirm their location and attributes supporting accurate records, design decisions, and construction activities.
Dye Testing
Kiwa T2 provides Dye Testing services to verify sewer connectivity, helping property owners, developers, and engineers identify where private sewer connections discharge into municipal infrastructure.
Site Characterization Support
Kiwa T2 provides advanced geophysical investigations that help clients understand subsurface conditions, identify anomalies, and make informed environmental, remediation, and engineering decisions.
FAQs about Railways
Does Kiwa support both freight and passenger rail?
Yes. We provide services for heavy rail, commuter rail, and light rail systems, including stations, crossings, and below grade infrastructure.
