CNA Consulting Engineers is an award-winning professional civil and mining engineering firm that provides services for projects built in, on, or using soil and rock materials. We have a 30-year track record of successful projects and satisfied clients on the local, national and international communities. We routinely assist clients with all phases of the project life cycle - from conceptualization through maintenance and rehabilitation.
Projects include, but are not limited to: work on underground transportation facilities and occupied underground spaces, utility tunnels, storm tunnels, sanitary tunnels, infrastructure evaluation, geostructural research and evaluation. Our firm also specializes in the design of inhabited underground space and frequently take the same role for underground projects that architects do for above-ground projects - the role of project leader and coordinator.
We often team with other firms to provide mechanical, electrical, fire protection, fire and life safety, outfitting and similar design services.

Services
Design of these underground structures is CNA Engineer's core business.
Our project history and expertise spans the full range of subsurface materials, depth, span, length, diameter, and use.
We have designed projects with a few feet of cover up to 5,000-ft deep; in soft ground, soft rock and hard rock.
Projects include storm sewer, sanitary sewer and other utility tunnels and shafts, occupied underground space, science facilities, transportation tunnels, and warehousing.
We specialize in developing management plans for tunnels and large-diameter pipelines.

A broad swath of the Midwestern United States from Pennsylvania to Kansas contains underground limestone mines.
When the limestone reserves are depleted, the mines are commonly converted to secondary uses like records storage, manufacturing, printing and commodity warehousing.
CNA Engineers provides owners and tenants with comprehensive facility assessment, design and conversion services for pillars, roofs and portals.

CNA Engineers plans and manages site investigations for surface and underground projects.
Included are site evaluations, geophysics, geologic and geotechnical mapping, borings and core holes, sample and core logging, and laboratory testing.
We conduct mapping, logging, and some types of geophysics.
We subcontract for boring, core holes, geophysics, and laboratory testing.
Every project has cost and schedule risks that must be identified, assessed, mitigated and assigned to project stakeholders.

Our firm prepares geotechnical data and geotechnical baseline reports, which are a critical means of communicating geotechnical conditions to project owners, designers and contractors.
Geotechnical data reports convey the information collected during site investigations.
They contain the factual information collected in the field and measured in the laboratory.
They are free of interpretations or statements about material behavior.
Geotechnical baseline reports provide clear and realistic baselines for conditions anticipated to be encountered during the project's construction.

We conduct rock and soil slope engineering as part of larger projects or as stand-alone projects.
Rock slope engineering projects arise in mining, tunnel approaches, bridge abutments and similar.
The orientation, spacing, continuity, infilling and strength of rock joints are the principal input to the kinematics analysis of rock slopes.
We analyze soil slopes using the traditional method of slices, and with continuum analyses using FLAC and FLAC3D.
Joint use of the two methods enhances the reliability of the analysis results.
