Brownfield and voluntary remediation projects protect human health and the environment while restoring beneficial use to properties. SCS Engineers is a pioneer in supporting the public-private partnerships for these types of redevelopment. In fact, SCS helped redevelop environmentally impaired real estate more than 25 years before the term “Brownfield” was coined.

Developers and owners, and operators of active facilities seek our services to clean up commercial and industrial properties before marketing the real estate for new uses. We also work with cities and counties to redevelop idle properties and place them back into productive use. Watch a video about our latest award-winning project.

Despite the development challenges presented by closed landfills, particularly with respect to differential settlement and gas migration, many former landfill sites offer prime locations for infill and other forms of smart growth. SCS Engineers has successfully completed scores of landfill redevelopment projects. We are a leader in enabling sites to be reused for active and passive end-uses that are environmentally safe and cost-effective. We have the expertise necessary to meet the unique environmental and regulatory challenges of developing solar on landfills and Brownfields. We assist our clients in evaluating the feasibility of converting non-productive real estate into revenue-generating assets.

Oil and gas companies protect themselves against future liabilities by properly remediating facilities as they are abandoned, demolished, or rebuilt. SCS participates in the successful remediation of upstream oilfield facilities, refineries, transport pipelines, abandoned sumps, etc. We offer scientific investigations and engineering designs and construction and long-term operations of remediation systems for contaminated air, soil, and water.

SCS Engineers understand the priorities of land developers, property owners, and local governments, and we offer practical solutions to a wide range of environmental problems. We are well-versed in regulatory concerns and have worked on voluntary cleanup and voluntary remediation projects under the jurisdiction of major regulatory agencies.

Our teams of professionals offer an integrated engineering and construction approach that starts with defining and analyzing the extent of contamination and the environmental problems you may be facing. This work is performed systematically, and clients can choose a turn-key solution or select services. View or download our list of helpful resources.

We start with a mix of the following inspections, studies, and assessments:

  • Site Inspections, including Phase I and other Property Assessments
  • Site Investigations, including Phase II and Phase III Investigations
  • Risk Assessment to determine whether active remediation is necessary and to help find acceptable end-uses
