Services
Civil Engineering
Our civil engineering services focus on land development, infrastructure design, and site planning for residential, commercial, and municipal projects. We provide grading plans, utility infrastructure, and permitting support to ensure compliance with local regulations. By collaborating with architects and developers, we create functional spaces that balance economic viability with community needs while prioritizing long-term sustainability.
Climate Resilience
We help communities and businesses mitigate climate change impacts through tailored resilience strategies. Our services include vulnerability assessments, nature-based flood protection, and decarbonization planning. By integrating green infrastructure and securing funding opportunities, we enable clients to implement adaptive solutions that enhance ecological health while protecting infrastructure from extreme weather events and rising temperatures.
Environmental Remediation
Our environmental engineers specialize in hazardous material assessment and remediation for industrial and urban sites. We conduct soil and groundwater investigations, manage emerging contaminants like PFAS, and ensure compliance with state and federal regulations. Through proactive risk management and stakeholder engagement, we transform contaminated properties into safe, productive spaces while minimizing client liability.
Facility Engineering
We optimize building systems for healthcare, manufacturing, and municipal facilities through mechanical, electrical, and plumbing (MEP) engineering. Our holistic approach integrates energy-efficient technologies and climate adaptation measures to reduce operational costs. By addressing compliance requirements and future-proofing infrastructure, we enhance facility functionality while supporting sustainability goals for long-term asset performance.
Landscape Architecture
Our landscape architects create resilient, accessible public spaces that combine aesthetic appeal with functional climate adaptation. Services include park design, streetscape improvements, and climate-resilient master planning. We emphasize context-sensitive solutions that preserve historic elements, enhance biodiversity, and incorporate green infrastructure to manage stormwater while improving community quality of life through inclusive, sustainable outdoor environments.
