ESPO Engineering is the civil design and utility permitting division of ESPO Corporation — a licensed Illinois design firm delivering construction-ready engineering for natural gas and telecommunications since 1965.
Design License No. 184.002122-0002
Our Story
ESPO Corporation was founded in 1965 as an engineering company — engineers and draftsmen working alongside utilities on design and field operations. Over the decades we saw that clients needed more than talented individuals — they needed a partner who could take ownership of the entire design and permitting process.
Our in-house civil design practice grew out of that work. Today, ESPO Engineering operates as a dedicated division, combining deep utility expertise with production-scale CAD capabilities to deliver permit-ready engineering drawings for natural gas and telecommunications infrastructure.
The tools have changed since the drafting table. We moved to in-house CAD production in 1995, and we are now shifting from drafting to declarative CAD environments: standards, title blocks and project data are declared once, and drawing sets are generated and checked from them rather than redrawn sheet by sheet.
Our civil production runs in AutoCAD Civil 3D — from directional bore plans and site plans to road crossing details and complete permit packages. We also perform GPS-based field mapping to capture existing conditions, though we are civil engineers, not surveyors.
With offices in Willowbrook, Illinois, we serve utility companies, general contractors, and engineering firms across the United States.
Timeline
ESPO Corporation founded as an engineering company — engineers and draftsmen supporting utilities in design and field operations.
Purchased an in-house CAD/Engineering Design Center, bringing design production under one roof.
Expanded into utility permitting — assembling complete permit packages for DOT, municipal, and railroad jurisdictions.
Started combining software engineering with civil permitting to automate and streamline the design-to-permit workflow.
Implemented AI initiatives to greatly enhance the permitting process — faster turnaround, fewer errors, scalable production.
Shifting from drafting to declarative CAD environments — drawing sets generated and checked from declared standards and project data instead of drawn sheet by sheet.
Site Plans & Civil Design

Field Mapping
We understand that permit delays cost money. Our production pipeline is built for speed without sacrificing accuracy.
We design to get approved. Our deep knowledge of DOT, municipal, county, and railroad requirements means fewer revisions and faster approvals.
From a single permit to a thousand-lot program, we scale our CAD and engineering teams to match your project demands.
Natural gas and telecommunications — we specialize in utility permitting and civil design for these two industries and do it better than anyone.
Tools & Technology
Our primary production platform is AutoCAD Civil 3D, but our design team works in whatever environment your project requires. We maintain current licenses and trained staff on all major civil engineering and GIS platforms.
Our Services
We focus on two disciplines — natural gas and telecommunications — and deliver the civil design and permitting services that get utility projects from planning to construction.
