Facilities & Utilities Management

GHA: Comprehensive Facilities & Utilities Management

At Gewalt Hamilton Associates, we place a high value on the critical role of Facilities and Utilities Management. We understand their crucial significance, where strict adherence to industry standards, attention to detail, and accuracy form the foundation of our operations. With more than 150 years of collective service, our team underscores our commitment to excellence in facilities and utility management.


GHA’s expertise spans a wide range of water and wastewater system operations, from managing potable water treatment facilities to operating pump stations, we also work closely with private labs for water testing quality to meet all EPA standards and reporting, and Supervisory Control and Data Acquisition (SCADA) systems. We understand the importance of preventive maintenance programs and are equipped to respond swiftly and efficiently to emergencies. A key aspect of our work is managing overall water and wastewater systems to reduce Inflow and Infiltration (I&I) in sanitary sewer systems, demonstrating our commitment to maintaining water system from daily operation to all required field inspection of assets, and this is a based on the long-term functionality of these critical utilities.


Our Storm and Sanitary Structure Data Collection project for the City of Urbana exemplifies GHA’s commitment to meticulous data collection and efficient infrastructure management. The project, which covers approximately 80% of the city’s storm and sewer structures, employs a custom GIS-based form to gather comprehensive data and directly integrates this information into the city’s GIS data model. The anticipated use of the CUES SPiDER Manhole/Structure Scanner on around 25% of the structures enhances the project’s efficiency, offering robust 3D models that help identify potential defects. This innovative approach highlights GHA’s passion for leveraging advanced technology to serve our clients effectively and with integrity.

City of Urbana - GPS Points


GHA has embarked on a comprehensive investigation and management project of the Village of Wheeling’s storm sewer system. Our team utilizes GPS technology to locate approximately 530,220 linear feet of storm sewer pipes and conducts thorough inspections of more than 10,000 storm structures. Through personalized GIS data integration, we provide a comprehensive stormwater master plan to the Village, offering valuable recommendations for their storm system management.

Land Surveying

GHA’s Land Survey Group brings a level of experience far beyond most firms, and applies this to an extremely wide range of project categories, types of surveys, and time constrictions.

Reliable Excellence in Land Surveying is the unsung hero of civil engineering. With so much riding on the accuracy and level of detail, it is urgent that surveyors adhere to industry standards and best-practices that yield high-quality deliverables that lead to informed design.

Possibly our most beneficial advantage is that GHA is a civil engineering firm. This means that our surveyors are intimately familiar with exactly what is done with our surveying deliverables and why. Performing surveys from the engineering perspective has proven to provide us a definite edge in deep detail, resulting in highest-quality data. This is the data that defines the entire balance of project design.

Construction Engineering

Proactive communication and effective coordination are vital to any project’s successful construction.

GHA Construction Engineering focuses on impeccable documentation, a firm but fair collaboration with contractors, and actively reducing uncertainty for those affected by construction activity.

In the engineering phase that takes all the planning and intensive design and makes it a reality, there is uncertainty that can be mitigated with the right approach. For contractor and material accuracy and compliance, our trained eye and reliable processes match the high level of performance sought by project owners when seeking the right consultant.

The enemy of confidence for construction project stakeholders is uncertainty. The actual inconvenience experienced is undeniably unpleasant, but what residents, commuters, and the local business community really fears is not knowing what is being done, how long it will take, and why.

Construction projects commonly involve changes and delays. This is counterintuitive to projecting the perception of intentional, well-planned construction activity. This leaves only preemptive timeliness as the most important tool. Over the years, it has been common to generate newsletters, flyers, and other communications channels to manage the emotions of project stakeholders.

We know that today’s immediacy is demanded by the public, and while hard-copy methods may still need to be included, the most helpful channel to connect with those most interested in remaining fully informed is a project-specific website GHA brings strong experience in utilizing a project-specific website to inform stakeholders about the project and is the most common method chosen and most conveniently consumed.


With our expertise in construction processes and documentation, our field staff can fulfill the requirements of state, county and local governmental agencies. We stay up-to-date with the most current design and construction standards in order to make expedient field changes as required.

Construction Observation

Site observation is imperative to construct a site which meets or exceeds local and federal standard specifications. We will attend all construction meetings with the design team and contractors, prepare field sketches and change orders, and review final payment processes.

NPDES Compliance Monitoring

We have certified National Pollutant Discharge Elimination Systems (NPDES) compliance monitoring personnel who verify that project sites meet or exceed best management practices as stated in ILR10 permit applications. Our field personnel inspect, document, report and photograph the relevant construction activity.
