Core Capabilities

Engineering Excellence at Every Stage

Fielding

Our field services team delivers accurate, technology-driven data collection and verification to support utilities, municipalities, and engineering partners at every stage of a project. From ground truthing and utility locating to asset inspections, as-built documentation, and construction observation, we ensure field conditions align with design intent and compliance standards. Leveraging mobile tools, IoT, and advanced sensors, we provide real-time insights, photographic documentation, QA/QC audits, and detailed reporting—giving stakeholders the confidence to make informed decisions and keep projects moving forward safely and efficiently.

GIS

Our GIS services deliver accurate, end to end geospatial solutions that support planning, design, construction, and long term asset management. We provide data collection, validation, and management, asset inventory and ground truthing, utility and infrastructure mapping, spatial analysis, and as built record mapping. Our team designs and administers geodatabases, integrates with engineering and CAD systems, and develops efficient mobile field workflows. Using aerial imagery, LiDAR, IoT integration, and custom applications, we create clear mapping, dashboards, and reliable data to drive smarter infrastructure decisions.

Survey

Our surveying services provide precise, reliable data to support land development, infrastructure, and construction projects from start to finish. We offer boundary and land surveying, construction and engineering surveys, geodetic and control surveys, and utility and infrastructure surveying, along with detailed topographic mapping, digital terrain modeling, and aerial and remote sensing solutions. Our team delivers construction staking for buildings, utilities, and roadways, as built surveys, and services for industrial and commercial sites. We also support permitting documentation, re establish section corners, monument record filing, legal descriptions, easements, flood zone certificates, and comprehensive survey solutions including ALTA NPSA land title, boundary, subdivision, and route surveys.

"I met the TWG team back in the fall of 2020, while working together on a very large audit for a major Utility company.  We were welcomed onsite to the Wheaton facility by the entire TWiG team.  The team rolled up their sleeves and worked diligently throughout the 12-month project.  They were willing to train, learn, and adapt, to ensure a successful project completion.  I have remained close with Josh Davis (President of the Will Group) and Stephaun Raines (Director of Business Development) since we initially met.  We have continued to work together on a few other projects since our initial meeting.  I would not hesitate to re-engage or partner with their team, on any future opportunities."

"I’ve worked with The Will Group extensively since 2021, focusing on field audits of overhead equipment.  They have been very focused on safety and process, with a bias towards quick action.  They have delivered on their commitments each time we’ve engaged them for work, and in many cases this follows storm events so they often receive very little warning.  In the few cases where we needed something adjusted, they responded quickly and effectively.  Overall, they are easy to work with and deliver on their commitments consistently and in a timely manner."

Growth Through Acquisition Growth Through Acquisition

Growth Through Acquisition

In April 2023, The Will Group took a significant step forward by acquiring Ruettiger, Tonelli & Associates, Inc., a respected engineering, design, and GIS firm. Building on this momentum, in November 2025, TWG further expanded its capabilities through the acquisition of The Upchurch Group. These strategic acquisitions have significantly bolstered TWG’s capacity to deliver comprehensive, turnkey solutions, with a particular focus on roadway, utility, and municipal projects. By combining our expertise with that of Ruettiger, Tonelli & Associates and The Upchurch Group, we now offer an even more robust suite of engineering services, leveraging decades of experience and deep industry partnerships to execute large-scale projects with exceptional precision.
