Broader capabilities

Transportation & Environmental Civil Engineering.

In addition to our flagship water and wastewater expertise, AEC delivers comprehensive transportation engineering, civil and site development, environmental compliance, and stormwater management: integrated, multidisciplinary infrastructure solutions across the Southeast.

All work is performed with the same principal-led attention to precision, safety, and long-term performance that defines AEC's water infrastructure projects.

Design-build & civil construction

Construction NAICS, backed by the work.

AEC is registered under construction NAICS codes, including 237310 Highway, Street, and Bridge Construction, in preparation for design-build pursuits. Design-build rewards a team that knows both sides of the contract: how a project is designed, and how it gets built, inspected, and closed out. That's where our record sits.

Transportation & highway infrastructure

Roadway, interchange, bridge, and drainage design, plus construction engineering and inspection on interstate work.

  • GDOT Transform 285/400CEI and QA/QC support for interchange improvements, including flyover ramps and collector-distributor lanes, across 10.5 miles of interstate.

Site preparation & site development

Grading, drainage, stormwater, utility coordination, and subdivision compliance that turn raw parcels into build-ready sites.

  • 925 Hank Aaron DriveCivil design, grading, drainage, stormwater management, and utility coordination for an Atlanta redevelopment.
  • Shell Building at 2103 Park PlazaSite grading, drainage, stormwater management, utility coordination, and three-lot subdivision compliance.

Concrete foundations & structures

Construction oversight, inspection, and materials testing coordination for concrete treatment structures.

  • Big Creek AWTP ExpansionOversaw construction of the headworks, aeration basins, chemical storage, and dewatering systems.

Commercial & institutional facilities

Site civil engineering for commercial buildings, and delivery on an active federal installation.

  • Shell Building at 2103 Park PlazaCivil engineering for a commercial shell building site.
  • Robins Air Force BasePrime contractor at the Avionics Repair Depot: 5,600+ industrial process waste tasks a year.

Construction management, CEI, QA/QC & field execution

Owner's-side contract administration, inspection, and quality programs, and the field execution that keeps work orders moving.

  • Big Creek AWTP ExpansionFull contract administration: submittals, RFIs, RFPs, change orders, and progress payments.
  • GDOT Transform 285/400Construction engineering, inspection, and QA/QC on major interchange work.
  • Robins Air Force BaseA three-tier QA protocol (team lead, safety/quality manager, project manager) on every work order over a five-year performance period.

01

Transportation Engineering

Transportation planning, roadway and interchange design, and construction engineering and inspection (CEI) that keep state and municipal mobility programs moving.

  • Transportation planning, modeling & safety improvement design
  • Intersection design, traffic management & multimodal integration
  • Roadway, bridge & drainage system design and analysis
  • Construction Engineering & Inspection (CEI) for oversight and QA
  • Collaboration with municipalities and DOTs on mobility and connectivity

02

Civil & Site Engineering

Site civil design, grading, utility coordination, and permitting that turn raw parcels into build-ready sites.

  • Site civil design, grading & utility coordination
  • Permitting support and subdivision compliance
  • Stormwater management integrated with site development
  • Infrastructure design for improved safety, mobility & resilience

03

Environmental & Stormwater Management

Stormwater conveyance, detention design, and environmental permitting that keep projects compliant, resilient, and built to last.

  • Stormwater conveyance design, detention/retention & erosion control
  • Flood mitigation, watershed management & green infrastructure (LID)
  • Environmental assessments, permitting & compliance (NPDES, SPCC)
  • Sustainable drainage systems and long-term resilience planning
