Your timely source for more cost-effective and less disruptive solutions to your underground infrastructure needs. The North American Tunneling Conference is the premier biennial tunneling event for North America, bringing together the brightest, most resourceful, and innovative minds in the tunneling industry. It underscores the important role that the industry plays in the development of underground spaces, transportation and conveyance systems, and other forms of sustainable underground infrastructure. With every conference, the number of attendees and breadth of topics grow. The authors—experts and leaders in the industry—share the latest case histories, expertise, lessons learned, and real-world applications from around the globe. Crafted from a collection of 126 papers presented at the conference, this book takes you deep inside the projects. It includes challenging design issues, fresh approaches on performance, future projects, and industry trends as well as ground movement and support, structure analysis, risk and cost management, rock tunnels, caverns and shafts, TBM technology, and water and wastewater conveyance.

In Community Benefits, Jovanna P. Rosen explores a new pattern in urban development: local residents and community representatives leveraging large-scale development projects for agreements that promise dedicated local benefits, such as parks and jobs. In general, such development projects have not produced impactful benefits for local residents, and often have contributed to significant community harm, including gentrification and displacement. In response, community activists have launched a fight to control development, using benefits-sharing agreements to ensure that projects produced better outcomes for local residents. While such agreements now exist across the nation, the process of negotiating and enforcing them remains challenging. This book dives deep into four case studies--in Los Angeles, Atlanta, Seattle, and Milwaukee--to answer the following questions: Who ultimately benefits from both the agreements and the projects in question? How do benefits get delivered, and who controls this process? What works for these agreements to successfully produce community outcomes? Rosen shows that, without agreements that promote accountability, developers and other project proponents can walk away from the negotiating table once the agreement is signed and the development moves forward. This disregard for community benefits and priorities can leave community residents solely responsible for benefits delivery during implementation, but with few viable avenues to ensure that outcomes materialize. The cases reveal specific elements that agreements require to achieve success during implementation: community participation, managerial connections, effective partnerships, responsiveness, and vigorous oversight with accountability mechanisms. Although creating these conditions is difficult, sometimes impossible, and contingent on fragile processes, Rosen concludes the book with recommendations for both the agreement negotiation and implementation phases to ensure success.
