This practice manual examines the Geotechnical Baseline Report (GBR) which establishes a contractual statement of geotechnical conditions anticipated during underground and subsurface construction. Emphasis is placed on large underground projects such as tunnels, underground chambers, shafts, subway stations, mine development, and deep foundation excavations that have a significant anticipated risk of differing site condition claims. Guidelines for what should be included in the GBR are provided, in addition to a checklist of items to consider, recommendations for the content and wording to be used in baseline statements to improve their clarity and precision, and examples of problematic and improved practice in stating baselines. The importance and benefit of ensuring compatibility between the GBR and other elements of the Contract Documents, with emphasis on the specifications, drawings, and payment provisions is also discussed.

Geotechnical Baseline Reports (GBRs) have become a prevalent risk sharing mechanism on North American tunneling projects as they are based on the following risk allocation concept: the subsurface ground conditions described within the GBR are the financial responsibility of the Contractor, whereas encountered conditions which exceed those described belong to the Owner. This interpretation is intended to reduce project bid prices due to subsurface ground conditions uncertainty and the geotechnical rationale for a differing site conditions claim. However, recent tunnel project case studies have used the GBR as a risk transfer mechanism by presenting a conservative and/or limited interpretation of the expected ground conditions. In particular, the expected ground conditions are described with a summary of the intact and rockmass properties and empirical rockmass classification systems. This research has shown that the application of intact rock properties and rockmass classification systems to describe the various rockmasses along the tunnel alignment leads to rockmass behavioural uncertainty. Empirical rockmass classification systems are not able to adequately capture the effects of geologic uncertainty and the collective impact of the individual controls on rockmass behaviour. A new rock engineering design tool was developed which utilized geologic uncertainty and the capabilities of numerical modelling methods to predict and quantify rockmass behaviours. The 3D Rockmass Behaviour Map reduces subsurface ground conditions uncertainty as the range of possible rockmass behaviours is presented as a function of the three critical geomechanics parameters. Quantifying rockmass behaviours per tunnel domain demonstrates the effects of geologic uncertainty with rockmass behaviour mode switching. GBRs should include this 3D Rockmass Behaviour Map and quantified rockmass behaviours as these tools reduce uncertainty in the expected ground conditions and provide a greater understanding of the anticipated rockmass behaviours. Rather than using a conservative GBR which shifts subsurface ground conditions risk to a Contractor, this improved prediction of the expected ground conditions may result in better subsurface risk allocation, reduced construction contingencies, aid excavation means and methods selection, reduced geotechnical basis for a differing site condition claim, and provide greater certainty in the final project price and schedule.

Tunnels and Underground Cities: Engineering and Innovation meet Archaeology, Architecture and Art contains the contributions presented at the World Tunnel Congress 2019 (Naples, Italy, 3-9 May 2019). The use of underground space is continuing to grow, due to global urbanization, public demand for efficient transportation, and energy saving, production and distribution. The growing need for space at ground level, along with its continuous value increase and the challenges of energy saving and achieving sustainable development objectives, demand greater and better use of the underground space to ensure that it supports sustainable, resilient and more liveable cities. This vision was the source of inspiration for the design of the logos of both the International (ITA) and Italian (SIG) Tunnelling Association. By placing key infrastructures underground – the black circle in the logos – it will be possible to preserve and enhance the quality of the space at ground level – the green line. In order to consider and value underground space usage together with human and social needs, engineers, architects, and artists will have to learn to collaborate and develop an interdisciplinary design approach that addresses functionality, safety, aesthetics and quality of life, and adaptability to future and varied functions. The 700 contributions cover a wide range of topics, from more traditional subjects connected to technical challenges of design and construction of underground works, with emphasis on innovation in tunneling engineering, to less conventional and archetypically Italian themes such as archaeology, architecture, and art. The book has the following main themes: Archaeology, Architecture and Art in underground construction; Environment sustainability in underground construction; Geological and geotechnical knowledge and requirements for project implementation; Ground improvement in underground constructions; Innovation in underground engineering, materials and equipment; Long and deep tunnels; Public communication and awareness; Risk management, contracts and financial aspects; Safety in underground construction; Strategic use of underground space for resilient cities; Urban tunnels. Tunnels and Underground Cities: Engineering and Innovation meet Archaeology, Architecture and Art is a valuable reference text for tunneling specialists, owners, engineers, architects and others involved in underground planning, design and building around the world, and for academics who are interested in underground constructions and geotechnics.

Geotechnical investigation, which is usually implemented to obtain baseline information of ground and groundwater, is the focus of this book. Authored by practitioner and academic who is extensively involved in geotechnical ground investigations over four continents, this book covers both large scale preliminary ground investigation and intrusive detailed investigation, as well as specialized in-situ testing to obtain advanced geotechnical parameters of soils. Both surface and borehole geophysical methods used in geotechnical investigation, including methods of sampling and tools to obtain good quality soil samples are also discussed and presented in the book.Written for advanced undergraduate and graduate students, researchers and practitioners in the fields of geotechnical engineering, geoenvironmental engineering, and ground investigation, the book also provides guidelines on presenting factual geotechnical data and preparing factual reports.Related Link(s)
