We relish the opportunity to work on unusual structures like gantry cranes, axle boxes for oil sands trucks, wind turbines, grain hoppers, conveyor structures, or service towers. Our team will conceptualize and design new custom structures and machines, upgrade existing industrial infrastructure, and repair problematic maintenance issues. Our expertise includes the following capabilities and markets:

Our work


Water and Wastewater


DCI supports water and wastewater treatment processes by designing equipment supports, steel and concrete tanks and covers, pipe racks and duct supports, foundations, platforms, and accessways. Our understanding of water treatment processes and criteria make us a valued and effective partner in the design of new plant maintenance equipment and process upgrades.

Metal Producers and Product Manufacturers


Working around routine production schedules and outages can require extensive planning, particularly with the installation of new customized equipment. Our industrial engineers understand that time is money and create solutions that can be installed and commissioned quickly and efficiently.

Custom Machine Design


As the owner’s representative or project manager, DCI assembles a design team and qualified fabricator to complete a turn-key solution. Our engineers work with our clients to develop new or enhanced custom machinery to improve their processes and profits.



We have worked on almost every power generation dam along the Snake and Columbia rivers. Our experience includes custom-built mechanisms for maintenance cranes, gate hoists, gates, fish mitigation, and navigation locks.

Mining and Material Handling


Our team designs material handling equipment for iron, coal, molybdenum, copper, and gold mines located around the world. From long-span conveyors to semi-mobile crushers, our team works with process engineers to design mining and material handling equipment which supports a variety of process systems and operations. With many of these projects being fabricated and installed overseas, we understand it is imperative that our drawings are complete, precise, and constructible.



Our seasoned engineers have more than 40 years of experience working with cranes of all types. Our vast knowledge of cranes includes: specialty and custom cranes, drive systems, hoist systems, rehabilitations, re-rates, trolleys, runways, loads tests, supporting structures, and below-the-hook lifting devices.

Power Generation and Transmission


Our staff has been the engineer-of-record for a variety of power generating systems: hydro, wind, solar, fossil fuel, biofuel, and nuclear, along with transmission infrastructure.



Much of our staff comes from small farming communities and appreciate the uniqueness of the industry. DCI addresses design needs for grain storage facilities, flour processing plants, and farming equipment.



DCI’s involvement with this market sector encompasses ports and port machinery. Our team can design upgrades or modifications to port machinery, such as cranes, spreaders, rubber tired gantries, straddle carriers, shuttles, and top lifts. We also design or modify piers, wharves, docks, quays, and warehouses.

Future-forward warehouse solutions.

The future of warehouse development and light industrial facilities requires a design mindset in touch with the fast-paced, modern day supply chain and movement of essential goods. DCI’s warehouse market experts have collaborated with developers seeking a competitive edge to their facilities which appeal to high-profile commercial tenants valuing customer service. Our engineers have interpreted built-to-suit warehouse design criteria to fulfill logistical operations of such environments – and the requests keep coming.

DCI designers who specialize in light industrial/warehouse facilities devise framing structures for buildings constructed in infill sites within dense metropolitan areas or strategic warehouse campuses in the suburbs. Building solutions have come in the form of multi-story urban warehouses or supersized facilities – each presenting challenging requirements and coordination. Undaunted by the project scale and scope, our design team can develop floor plans with generous column spacing, tall floor-to-floor heights, large bay dimensions, and specific loading criteria. Our past warehouse accomplishments have been recognized by state concrete industry organizations.
