Design and Manufacturing of Precast Segments

This course is designed to educate the industry, especially the design and engineering community, about the technical details and current product advancements/trends with the design and manufacture of precast concrete tunnel segments.  This course will help to show that all of the componentry and designs involved in segment production must work together as a single system and not independent parts.

This course is designed for engineers and designers who wish to learn about precast segment design.  This course is geared toward anyone who is interested in learning more about precast segments in general, from design, construction, and installation. It is helpful if registrants have a basic knowledge of precast segments.

Grouting Used in Underground Construction and Tunneling

This one-day short course will present an overview of the materials, equipment and the various grouting methods used in association with underground construction and tunneling in soils and rock.  Subjects covered will include cements and admixtures, grouting equipment and practices, chemical and cementitious permeation/consolidation grouting, jet grouting, compaction grouting, pre-excavation grouting, backfill and contact grouting and cellular grouts. Ten industry experts will give the lectures on these various grouting subjects and techniques. This course is recommended for contractors, engineers, owners and consultants involved in any aspect of underground design and construction.

Recommended Contract Practices for Underground Construction Workshop

Make your mark on the second edition of this valuable reference manual. The UCA is working on a revision to the 2008 Recommended Contract Practices for Underground Construction, edited by W. Edgerton, which updated the 1974 Better Contracting for Underground Construction Manual. The updated manual will review emerging trends in contracting practices and recommend “best practices” for owners and other project participants. The primary focus is still underground construction: Tunnels and shafts for highway, rail, water, wastewater, and other uses. We will review and build consensus for best practice recommendations, especially those that address industry needs that are new and different since the first edition of the book was published. This workshop is free of charge and promises to be an open forum for exchange of ideas. The Committee hopes individuals who represent a broad spectrum of experience, background and geography will participate. 

If you are also interested in reviewing chapter text ahead of the workshop, please contact editor Sarah Wilson at The manual includes chapters on the following topics: Relationships; Project Planning; Subsurface Conditions; Risk Management; Design and Construction Management; Cost Estimates; Schedules; Pricing and Payment Provisions; Contracts; Changes; Dispute Resolution; and a new chapter on Insurance.
