Civil Engineering
Experienced & Adaptable
LHB opened for business in 1966 as a civil engineering firm, and our team has designed hundreds of civil projects in the decades since then. We have applied our skills and knowledge to a wide range of projects, including roads and bridges, site grading and storm-water management, utilities design work, and more.
Project Diversity
Our portfolio spans a range of markets, from commercial to industrial, residential to educational, municipal to military. We regularly design transportation infrastructure and utility expansions and renovations, but we also tackle unique challenges: For example, we have designed snowmaking water supply systems for ski resorts and fluid capture-and-reuse systems for deicing aircraft in cold weather.
Client & Community Focus
We are committed to our clients and are passionate about the civil engineering we do in local communities. We focus on providing practical and sustainable solutions, and we seek to earn the trust and respect of every client—so we can build partnerships that last.
Dedicated to Design Excellence
The LHB team is known for its dedication, responsiveness, and attention to detail. We believe that each client—no matter the size and scope of their project—deserves our best work and the highest quality product we can offer.
