Harper-Leavitt Engineering, Inc. (HLE) is a full service engineering, surveying and materials testing consulting firm. Organized in 1969, HLE has served Southern Idaho, Montana, and Western Wyoming providing personal service to its clients. We have offices in Idaho Falls and Blackfoot, giving us the ability to quickly respond to client needs.
Planning and Land Development
Residential, Commercial, Educational, Industrial, Retail, Parks

HLE offers full services to those in the Land development Industry. We can start with feasibility studies. We work with the developer to rezone, subdivide, annex, and/or plat property - providing necessary survey services. If a real-estate transaction is necessary, we often provide an Environmental Site Assessment report.

To prepare for the design phase of a project we perform geotechnical soils investigations for foundation and pavement design.

Using the survey and geotechnical information, our engineers work together with the client or design team to develop the civil design drawings including: Site Layout, Utility Design, Storm Water and Site Grading Design. Often construction requires a Storm Water Pollution Prevention Plan (SWPPP) for the National Pollutant Discharge Elimination System (NPDES) permit. When construction begins, our staff begins construction management, materials testing, and inspection.

In conjunction with land development we also provide support and design services for the water resources, and transportation business sectors.

Geotechnical Engineering and Materials Testing

The Geotechnical Engineer has a role in every project that involves earth structures, that requires a foundation in soil or rock, or that is constructed below the ground surface. Our engineers and technicians work to provide solid information for design, and follow up with inspection and testing to ensure that their recommendations have been accurately interpreted and implemented into construction.

HLE has a materials testing lab in the Idaho Falls office. We provide testing of soils, asphalt, and concrete through out the region. All testing conforms to ASTM standards.
