Soils Testing — Subsurface Investigation

Design and construction of functional and cost-effective structures require a thorough understanding of local soil, rock and groundwater conditions. High Plains Engineering & Design, LLC provides a wide range of services to support all phases of a project, from preliminary design through completion of the building process.

The experience and expertise of engineers and technicians throughout our company, can help to assess the construction and long-term performance risks associated with subsurface conditions. We participate as a vital member of the project team, focusing on project objectives and using innovative technologies to provide practical design recommendations.

Percolation Testing — Soil Percolation Testing for Septic Design

A percolation test is performed by measuring the permeability of the soil to properly size a septic field. Our geotechnical department has the knowledge and experience to accurately assess the soil conditions and site to design the most economical septic system for your site.

Septic Design — For Your Health and For Years to Come

Engineered Septic Designs are required when the percolation rate is less than 5 minutes per inch (mpi) or greater than 60 mpi and/or sites that have limiting layers within 5 feet of existing grade. All rural commercial sites require engineered septic designs regardless of the percolation rate. We provide engineered septic designs that meet county specific regulations.

The types of systems that we design include:

  • Low pressure drip irrigation systems
  • EvapoTranspiration (ET) systems
  • Conventional "Rock & Pipe" systems
  • Infiltrator® systems
  • "Green Design" shredded tire systems
  • Pre-Treatment systems for clustered sites

Grease Interceptors for commercial service and food establishments can be designed for your existing hydraulic loading or proposed addition.

We work in concert with associate Engineers, Surveyors and General Contractors to coordinate full Waste Water Treatment Facilities (WWTF) design with optional Design-Build capabilities to streamline your project.

Foundation Design — The Importance of Structure

Foundation Designs transfer loads from structures to the earth with either a shallow or deep foundation system. We provide both types of foundation designs for a variety of structures from a residential home, steel frame building, reinforced concrete tank, loading dock, light or sign pole bases, weigh scale, or full structural design for Dairy Facilities.

Below are some samples of different methods for a Foundation design:

  • Modular Home Foundation with Wood Wall
  • Stick Built Foundation
  • Drilled Pier Foundation

Structural Floor Design — For Stability on Expansive Soils

Structural floor designs are required for homes being constructed with a drilled pier type "deep" foundation to provide a separation between the expansive soil and the basement floor.

Framing Plans

Framing plans can be developed for a new home design or addition. These plans typically specify floor joist sizes, wall studs, headers, porch & deck beams, shear walls, and balloon walls as needed.

Construction Ready House Plans

We supply floor plans drawn to your layout and four elevations (front, rear, each side) that reflect your vision. Structural plans include shear wall (were required), wall framing, floor framing, header sizes and a roof layout (trusses are supplied by truss company) Bring your floor plan in to discuss transforming your dream into reality.

Project Management — Multi-Discipline Projects

High Plains Engineering and Design is well versed in Multi-Discipline Projects. Our company is a multi-discipline firm and knows what it takes to coordinate projects in an orderly manner that can be taken from concept to design to construction. We provide Project Management Services for project that require multiple Engineering Disciplines such as Mechanical, Electrical, and Civil Engineering. By integrating all of these disciplines under one roof, our clients have the ability to have one point of contact by teaming with a company that is small enough to be responsive to our clients needs, while still producing quality engineering at affordable prices.

Design/Bid/Build & Design/Build

Design/Bid/Build versus Design/Build? No matter which construction method you chose, High Plains Engineering and Design is the correct partner for you. Our staff has a deep knowledge of both construction processes and is capable of handling both. Our firm works as a great complimentary partner to any strategic team. We believe that good coordination and communication are keys to providing a high quality integrated design.

Grading & Drainage

Grading and Drainage is almost always required by municipalities prior to construction. The key to a good grading and drainage plan involves understand the existing site conditions and developing your grading plan around the new design in order to achieve the required and desired drainage. The regulations surrounding water runoff are constantly changing. Allow High Plains Engineering to navigate this with and for you. Laws govern every facet of water management from where water can be taken, how it is managed, how it affects neighboring properties, the chemicals and silt that could be running off, and even the plants and wildlife habitat created by wet locations. We make it our job to know how to help you in all of these situations and provide solutions for whatever situation you may have.
