Decades of Delivery. Every Discipline.
The following represents a cross-section of the engineering leadership and project delivery experience GES brings to every engagement — from early concept and FEED through detailed engineering, construction management, commissioning, and project turnover.
Client names and specific project identifiers are withheld in accordance with confidentiality agreements. Scope descriptions, technical details, and outcomes reflect actual project experience.
Transmission, Gathering & Distribution Systems
GES has led engineering on natural gas transmission, crude oil gathering, refined products, and water pipeline systems ranging from 4-inch distribution mains to 42-inch interstate transmission lines. Our pipeline engineering scope spans route selection, hydraulic modeling, stress analysis per ASME B31.4 and B31.8, alignment sheet production, and full IFC drawing packages.

Horizontal Directional Drilling & Trenchless Crossings
GES has designed and provided on-site technical oversight for more than 100 HDD crossings of navigable waterways, interstate highways, railroads, and environmentally sensitive areas. Our HDD engineering scope includes bore path design, drill string stress analysis, pullback load calculations, drilling fluid programs, and real-time technical support during drilling operations.

Representative Projects
Red River Crossing — 36-Inch Crude
1,800-foot HDD bore across a navigable waterway. Zero lost-circulation events. Pullback completed in a single continuous operation.
Interstate Highway Crossings Package
14 TXDOT highway crossings for a 34-mile renewable energy interconnect. All permits secured prior to contractor NTP.
Urban Wastewater Force Main
2,200-foot HDD bore through a developed urban corridor — zero service interruptions, zero surface settlement, zero utility conflicts.
Railroad Crossing Program
UPRR and BNSF crossing approvals for a South Texas pipeline project — secured in 9 weeks, 3 weeks faster than industry average.
Field Execution, Quality & Safety Oversight
GES construction management teams have overseen more than $2 billion in pipeline and infrastructure construction. We embed experienced construction managers, quality control inspectors, and safety professionals directly in the field — managing contractors, enforcing specifications, resolving field issues in real time, and protecting our clients' schedule and budget.

Representative Projects
East Texas Transmission Pipeline
68 miles of 30-inch natural gas transmission — three prime contractors managed simultaneously. Completed 11 days ahead of in-service date, 2.3% under budget, zero recordable incidents across 340,000 field labor hours.
Compression Station Construction
30,000 HP compression station — project recovered from a 6-week schedule deficit to deliver on the original in-service date.
Offshore Platform Tie-In
Subsea pipeline tie-in and platform modifications in the Gulf of Mexico — managed concurrent offshore and onshore construction scopes.
Municipal Water Transmission Main
12-mile, 24-inch water transmission main — full-time construction oversight, hold point inspections, and final acceptance testing. System passed all pressure and flow tests on first attempt.
Independent Technical Representation for Owners
When owners need an independent technical voice — to review contractor deliverables, manage EPC performance, or provide expert oversight on complex projects — GES serves as owner's engineer. We have identified and corrected design errors, recovered schedule on troubled projects, and protected owners from unsubstantiated contractor claims totaling millions of dollars.
Scope of Services
Clients Served
Representative Projects
Regional Water Authority — Force Main
Independent design review identified a hydraulic grade line error before construction — estimated $340K in rework avoided. Project delivered on original schedule.
Midstream Operator — Gathering System
Owner's engineer for a 120-mile gathering system expansion — reviewed all EPC deliverables, managed 14 contractor RFIs, and led final commissioning and turnover.
Industrial Facility Expansion
Owner's representative for a $180M industrial facility expansion — managed three EPC contractors and coordinated with regulatory agencies through startup.
Compression Station Recovery
$1.2M in unsubstantiated change order claims identified and rejected. EVM reporting framework adopted by client for all future major projects.
Highway, Railroad, Waterway & Utility Crossings
GES has engineered and permitted crossing packages for some of the most complex infrastructure corridors in the country — interstate highways, Class I railroads, navigable waterways, and environmentally sensitive areas. We manage the full crossing lifecycle: engineering design, permit application, agency coordination, construction oversight, and post-construction documentation.
Scope of Services
Clients Served
Representative Projects
Wind Farm Interconnect — 23 Crossings
All 23 crossing permits secured prior to contractor NTP — 14 TXDOT, 6 county road, 2 railroad, 1 waterway. No crossing-related schedule delays during construction.
Interstate Pipeline Crossing Program
Multi-state crossing permit program for a 340-mile interstate pipeline — 47 crossings across 6 states, all permits in hand before construction mobilization.
Urban Utility Conflict Resolution
Utility conflict identification and resolution for a major urban pipeline project — 112 utility conflicts identified, engineered, and resolved without a single construction delay.
Federal Lands Crossing Package
BLM and Forest Service right-of-way permits for a 60-mile pipeline through federal lands — coordinated with four federal agencies simultaneously.
Federal Agency Projects & Heavy Civil Infrastructure
GES has delivered engineering and project management services on federal agency projects, military installations, and heavy civil infrastructure. Our team understands the unique requirements of federal contracting — agency coordination, compliance documentation, and the discipline to execute within the constraints of government project delivery.

Concept & Feasibility
Route studies, feasibility assessments, preliminary cost estimates, and regulatory screening to define the project before committing capital.
FEED
Front-end engineering and design that locks in scope, schedule, and budget — and produces the basis of design for detailed engineering.
Detailed Engineering
Complete IFC drawing packages, material specifications, equipment data sheets, and procurement support.
Construction Management
Embedded field teams managing contractors, enforcing quality, tracking schedule and cost, and resolving issues before they become claims.
Commissioning & Turnover
