Preface

Thisis the fourth of seven volumes containing the full collection of paperspresented at Geo-Congress 2020: Vision, Insight, Outlook on February 25-28,2020 in downtown Minneapolis, MN. These seven volumes include well over 400contributions that span the 20 topic areas of the ASCE Geo-Institute's standingtechnical committees as well as 11 special topics unique to Geo-Congress 2020:

• Geotechnics of Coasts, Oceans, Ports, and Rivers:

Subaqueoussediment characterization; slope stability problems; slope and coastal erosionproblems; geotechnics of numerical and field studies of marine foundations. "Common Ground"

• Geotechnical Issues Shared by the US and Canada:

Borderprojects and topics of international interest; Example: Projects along thegreat lakes, peat, permafrost, and railways.

• 50th Anniversary of Minnesota Geotechnical Society (MGS):

Universityof Minnesota 68th Annual Geotechnical Conference; Kersten Lecture; Invitedinternational speakers; Local and regional projects and case histories; Example:Geotechnics of MN sports stadiums.

• The Geotechnics of Alternative Project Delivery:

Impactof project procurement (traditional, CMGC, DB, P3) on geotechnics;Performance-based work.

• Geo-Education:

Trendsin geotechnical engineering education; Incorporating research into education;Use of case histories in education.

• Construction, Inspection, and Monitoring:

Innovativemonitoring techniques; UAS inspection; LiDAR; Photogrammetry; Thermal imagingin geoconstruction.

• Advances in Geo-Computing:

Cloudcomputing; Numerical methods; Visualization techniques; Geotechnicalengineering and the fourth dimension.

• Geo-Systems:

Integrationof geotechnical engineering with other science and engineering disciplines;Biogeotechnical engineering; Geo-structural engineering; Hydraulics; Scour-soiltransport; Beyond the thermal pile: geothermal application.

• Geo-Forensics:

Hindsightis 20/20: failure case histories; Multi-disciplinary teams for geotechnicalfailure investigations; Have we really learned from past failures? Does historyalways need to repeat itself?

• Geo-Ethics:

Sociallyresponsible geotechnical practice; Reporting of geotechnical data; Are we asconfident as we appear on paper? Geotechnical engineers, risk, responsibility,and the legal system.

• States of Stress:

Examiningchallenges of our practice; Moving forward in a dynamic and rapidly changingworld; Responding to the priorities and needs of civil infrastructure withinthe constraints and demands related to time, talent, budget, coordination, andcommunication.

Of the topics above, the first three are an outcome of partnerships with the Coasts, Oceans, Ports, and Rivers Institute (COPRI) of ASCE, the Canadian Geotechnical Society, and MGS. Additionally, papers were solicited and submitted in collaboration with the Center for Bio-mediated and Bio-inspired Geotechnics directed by Dr. Edward Kavazanjian from Arizona State University. A number of papers were also received as part of special sessions proposed by conference participants.

The seven volumes in this series for Geo-Congress 2020 include five volumes arranged by topic area and two special volumes: one dedicated to the emerging field of biogeotechnical engineering and the other dedicated to papers collected and reviewed by MGS on the occasion of its 50th Anniversary. Each of the seven volumes are Geotechnical Special Publications (GSPs), containing papers that were reviewed in accordance with ASCE GSP standards. Each paper was subjected to technical review by two or more independent peer reviewers, and publication required concurrence by at least two peer reviewers.

The Editors gratefully acknowledge the immeasurable contributions of the countless individuals who made Geo-Congress 2020 and these published proceedings possible, especially the reviewers, sessions chairs, organizing committee members, and ASCE staff listed in the acknowledgement
