Headquartered in Indianapolis, IN and founded in 1945, BLN has successfully completed engineering projects for over half a century. BLN's longevity can be credited to two core principles. First, that we honor our commitments. When BLN agrees to provide a service, that service will be provided under the terms agreed upon. Second, that we stand behind our work. If a problem surfaces on one of our projects, we are the first to the table to help solve the problem and accept responsibility when appropriate. Our company has a professional staff of more than 100 engineers, designers, surveyors, environmental analysts, GIS consultant/analysts and other specialists.

Our project management and communication style is built from the philosophy that authenticity is the building block of trust. How we approach each project and client interaction echos in this philosophy. On each project BLN is a part of, we propose a communication plan be developed between the client and our team. Having an open communication plan in place ensures a smooth project, from start to finish. We know this approach is appreciated when 9 out of every 10 are repeat clients. From local municipalities to statewide DOTs, we give 100% toward every project.

Beam, Longest and Neff (BLN) is an award-winning consulting firm with experience in all facets of infrastructure projects. Founded in 1945, BLN has provided decades of expertise as a consulting firm. Guided by third generation leadership, the core group of BLN partners and associates strive to remain leaders within the consulting community. Our history and experience has helped us define a clear vision to work toward total client satisfaction.

BLN has one of the most knowledgeable and skilled Environmental Services departments in the country. Recent federal environmental policies have made it necessary for companies to utilize a team with the ability to address complex regulatory requirements. Our team has a thorough understanding of the environmental disciplines with extensive experience in key areas including resource management, agency coordination, and schedule/budget awareness. Our team has the ability to comply with all federal, state, and local regulations to ensure our clients obtain the appropriate approvals and permits to complete any project.


We provide a team who will continually focus on meeting any challenge given. We will work closely with you, delivering excellent service set by our own high standards based on these four values: safety, expedient decisions, proper and timely documentation, and constructing the project the right way. Our Construction Services discipline oversees all construction activities, using a clearly defined method of approach to construction inspection projects. Our project supervisors and inspectors keep close watch on every detail of a construction project: daily inspections, document control, change order management, testing, Quality Assurance/Quality Control (QA/QC), Maintenance of Traffic (MOT), work zone safety, and ensuring contractors stay on task, schedule, and budget.


Conducting surveys of the highest accuracy is one of the fundamental components of our business, and BLN offers a full complement of surveying consulting services for our clients. The survey team is equipped with the latest technology for both field and office, allowing our staff to work independently and proactively as needed during all phases of a project's route survey. This results in time and cost savings for our clients. Adding efficiency, our field crews are equipped with GPS receivers and laptops to process their own field data quickly after collection.

We pride ourselves on our ability to provide practical designs that meet time and budget requirements. Our goal is to provide you with solutions that enhance the community through improved traffic flow, safety, aesthetics, sustainability, and much more. BLN helps clients with personalized solutions that exceed project goals and community needs.
