  • Site restoration
  • Engineering for plant Isolations and reroutes
  • Engineering Estimate Development for Budget

Fuel System Design

APTIM’s experienced team of engineers and architects are able to provide customized fueling system designs to meet our client’s needs. We have designed fueling systems for backup power systems, sewer and water pumping stations, commercial and retail fuel stations, aviation systems, and naval refueling facilities. We pride ourselves on our ability to provide robust and cost-effective solutions for our clients. Learn More

Our team’s knowledge of federal, state and local requirements and experience on designing a variety of fueling systems allows projects to seamlessly transition to construction without surprises. Our experience includes:

  • Facility assessment, design, and construction
  • Package fueling systems
  • Backup power and pumping systems
  • Distribution design
  • Leak detection and repair
  • API 570/653 inspections
  • Cathodic protection inspections
  • Lube oil systems

Remediation System Design and Construction

APTIM has extensive experience with remedial system design, construction and operation. From small scale remedial projects such as source removals or interim measures to address localized impacts, to large scale complex system that will operate for years to mitigate larger contamination issues, APTIM’s engineers and geologists can provide remedial alternatives and approaches to meet your objectives and goals. Our capabilities include:

  • Traditional systems (P&T, AS/SVE, DPE, source removal)
  • Innovative systems (bioremediation, ISCO, recirculation, thermal)
  • Emerging contaminants remediate alternatives (PFAS, 6DDP)
  • All Impacted media (soil, water, sediment, air)
  • All contaminants (solvents, petroleum, metals, emerging contaminants)
  • In-situ and ex-situ systems
  • Pilot studies and bench scale testing
  • Operation and Maintenance

Stormwater Design

With increased awareness of the impact of run-off on water bodies as well as downstream flow implications, we support our clients with stormwater collection systems at new facilities or retrofit/upgrade of collection systems at existing facilities.  Based on the overall requirements of a project and permitting authorities, our team of engineers will tailor a best-fit solution to capture and treat stormwater run-off. Learn More

These solutions may include:

  • Design and construction of retention basins or holding tanks
  • Surface water management and segregation
  • Design and installation of oil/water separators
  • Development of erosion control measures such as grading or planting vegetation
  • Facility conveyances and berms the manage stormwater flow
  • Modeling applications (SWMM, ICPR, etc.)
  • Pump stations
  • Permitting

Small Capex Design and Oversight

APTIM can provide turnkey solutions for small (<$10 million) CAPEX design and oversight projects.  We understand these projects, while smaller in budget outlay, can be quite complex and require the same level of attention as larger projects. APTIM has provided engineering support on a variety of projects including facility turn-arounds, petrochemical industry, and port facilities.

Depending on our clients needs, we also provide construction oversight, third-party design review support, and litigation support.  We can also act as the Project Manger Consultant (PMC), Engineer, Procurement, and Construction (EPC) contractor, or Engineering, Procurement, and Construction Manager (EPCM) contractor.  As part of our approach, we strive to act as a partner in completing these projects on-time and in-budget.  Typical services include:

  • Process study and conceptual design
  • Facility retrofits & upgrades
  • Technology selection
  • MEP detailed design services
  • Modularization applications
  • Value engineering & cost estimating
  • Procurement support
  • Commissioning and start-up
