Collaborative Consulting is a structured partnership model in which PEC and peer environmental consulting firms agree to work together on a bilateral basis. Each firm contributes its unique strengths — whether that is geographic reach, technical specialization, regulatory relationships, or industry-specific experience — to deliver a unified, high-quality service to the end client.
This model is not subcontracting. It is a true professional partnership, where both firms maintain their standards, share knowledge, and coordinate directly to serve the client's best interests. PEC acts as either the lead consultant or the supporting partner, depending on the nature of the engagement.
The result is a network of trusted environmental professionals who can collectively serve clients across the country — from urban commercial corridors to rural industrial sites — without sacrificing quality, communication, or accountability.
PEC brings more than 100 years of combined team experience across multiple industries and environmental disciplines. A partnership with PEC means access to a proven, professional team that is committed to delivering results — for your clients and for yours.
Serve clients in markets where your firm's direct presence is limited, backed by a trusted local or regional partner who knows the regulatory landscape.
Access PEC's expertise in Phase I/II ESAs, site characterization, remediation, and environmental compliance to supplement your firm's capabilities on complex or multi-discipline projects.
Scale up quickly to meet client deadlines or handle project surges without the overhead of permanent staff additions — a flexible, professional solution for both firms.
Clients receive a seamless, coordinated experience regardless of which firm is leading a given task — because both partners are aligned on standards, communication, and deliverables.
A bilateral partnership opens doors for both firms — referrals, joint proposals, and shared market presence that grow both businesses over time.
PEC's team brings experience across oil & gas, technology, manufacturing, chemical, and real estate sectors — providing cross-industry insight that strengthens any project team.
PEC seeks collaborative partnerships with environmental consulting firms that share our commitment to quality, professionalism, and client service. Our ideal partners include:
Firms with strong local market presence and regulatory relationships who are looking to expand their service offerings or geographic footprint through a trusted national partner.
Firms with deep expertise in specific disciplines — such as vapor intrusion, ecological assessment, or industrial hygiene — who complement PEC's core ESA and remediation capabilities.
Growing firms that are building their client base and project portfolio, and who benefit from the mentorship, capacity, and professional network that a PEC partnership provides.
Civil, geotechnical, or environmental engineering firms that need a dedicated environmental consulting partner to handle Phase I/II ESAs and regulatory compliance as part of broader project delivery.
Reach out to PEC to introduce your firm and discuss your current capabilities, geographic coverage, and the types of projects or clients where a partnership could be mutually beneficial. There is no obligation at this stage — just an open, professional conversation.
PEC will evaluate the potential partnership for complementary strengths, shared values, and mutual opportunity. We look for firms that prioritize quality, transparency, and client service above all else.
Once alignment is confirmed, PEC and the partner firm establish a simple, clear framework agreement that defines the terms of collaboration — including roles, responsibilities, billing arrangements, and quality standards — for future engagements.
The partnership is activated on a real project, with both firms working together under the agreed framework. PEC prioritizes clear communication and a smooth experience for both the partner firm and the end client.
As the partnership matures, both firms actively refer work to each other, collaborate on proposals, and grow their combined capacity and market presence — creating lasting value for both organizations and their clients.
PEC is proud to partner with a distinguished network of environmental consulting and construction firms across the United States. These partnerships allow PEC to expand capacity, extend geographic reach, and deliver exceptional service to clients nationwide — bilaterally and professionally.
