What We Do
Integrated technical services, end to end
From first field measurement to final deliverable, our teams combine precise data capture, disciplined geospatial data management, and ongoing inspection support to keep every phase of your infrastructure program on track.
Field Data Collection
Topographic and utility surveys captured at survey-grade accuracy using GNSS and total-station equipment.
UAS / USV data capture
Drone and uncrewed surface vessel capture for fast, safe, high-resolution data over difficult sites.
Geospatial database development
Structured, standards-compliant GIS databases built for scale, data integrity, and easy integration.
Mapping and Visualization
Mapping-grade data collection and visualization that make spatial data usable.
Drafting & Design
Precise for-construction and as-built CAD deliverables, built to client drafting standards.
Atmospheric & Leak Surveys
Scheduled atmospheric inspections and leak surveys that keep pipeline integrity monitoring on track and compliant.
Aerial Span Inspections
Drone-based inspection of aerial pipeline spans, identifying issues before they become failures.
Waterway & Geohazard Assessments
Waterway crossing inspections and geohazard identification that protect pipeline integrity through sensitive terrain.
ROW Assessments
Right-of-way condition assessments that support encroachment monitoring and compliance.
Who We Are
Built for infrastructure
Centerline Technical Services supports midstream pipeline and energy infrastructure projects with integrated surveying, GIS, and geospatial expertise. We pair field-proven data capture with disciplined data management to deliver dependable, standards-compliant results.
As a division of The HR Group, we bring the resources and accountability of an established organization to every engagement — from the first survey data to the final CAD and GIS deliverable.
- Mapping-grade or survey-grade accuracy
- In-house QA / QC
- UAS & USV capabilities
- Midstream pipeline expertise
Where We Work
Built for the sectors that power communities
Midstream Pipeline
Precision surveying, GIS, and inspection support across gathering, transmission, and storage infrastructure — built on direct experience with leading midstream operators.
Oil & Gas
Field-proven geospatial and technical services supporting upstream and downstream operations, from site development through ongoing asset management.
Electric & Power Utilities
Extending our surveying, GIS, and UAS capabilities to support transmission and distribution infrastructure as utility demand grows.
Public Infrastructure
Reliable survey and GIS support for civil and public-sector projects, built on the same standards of accuracy that power our energy work.
How We Work
A clear path from field to deliverable
Capture
Field crews and UAS teams collect mapping-grade or survey-grade GNSS and drone data — matched to the accuracy your project actually requires.
Process
Every dataset runs through structured multi-point QA/QC before it moves downstream.
Deliver
Clean, compliance-ready CAD, GIS, and mapping deliverables — built to drop straight into your workflow.
