Underground Construction Information Management System for itmsoil

2026-04-02T16:45:52-06:00November 22nd, 2024|

An underground construction information management system (UCIMS) was developed by itmsoil to monitor construction data from the new east–west rail link across London known as the Crossrail. The Crossrail project construction works, Europe's biggest construction project, includes underground development, comprising shafts, tunnels, and portals that extend beneath the already congested London underground. Given the urban environment in which tunneling and other construction are occurring, monitoring of the construction works and of the impact on adjacent underground and aboveground structures were key activities for the project management and engineering teams. The UCIMS monitors tens of thousands of real-time geotechnical instruments and structural sensors as well as overall construction progress. In addition to performance monitoring of a host of construction activities, the UCIMS also tracks the progress and performance of tunnel boring bachines. The UCIMS was designed to provide real-time access for all stakeholders to the construction and instrumentation data, and it called for an intuitive, map-based user interface, showing progress and data locations relative to the surface features and other spatial information.

Detailed Site Assessment and Long-term Management Strategy for a Nitrobenzene DNAPL Impacted Site

Historical nitrobenzene production operations resulted in nitrobenzene dense non-aqueous phase liquid (DNAPL) impacts at depth within a stratified alluvial aquifer. An associated nitrobenzene groundwater plume was discharging to an adjacent river.

Vapor Intrusion Assessment Near a Residential Development in United Kingdom

In 1993, as a result of corporate safety, health and environmental policies, the client initiated a review to assess potential hazards to human health and the environment resulting from historical industrial waste disposal activities.

Enhanced In Situ Bioremediation of a DNAPL Source Area in United Kingdom

The application of enhanced in situ bioremediation for the treatment of chlorinated solvent source areas, referred to as dense non-aqueous phase liquid (DNAPL), offers major potential as a technically and economically effective remediation option. Project SABRe (Source Area BioRemediation) was designed to develop and demonstrate that enhanced anaerobic bioremediation can result in cost effective and quantifiable treatment of chlorinated solvent DNAPL source areas. Geosyntec was a key member of this collaborative project that was undertaken and financed by a multidisciplinary team from the United Kingdom, United States, and Canada, forming a unique industry-regulatory- academic partnership.

Evaluating Functional Stability and Completion of Landfill Aftercare in France, Italy, and the UK

Optimizing and completing post-closure care (PCC), or aftercare, of closed MSW landfills in Europe is a major issue facing SITA, the waste services arm of Suez Environnement. Working with the French Agency for the Environment and Energy (ADEME), Suez and SITA turned to Geosyntec to investigate application of the performance-based Evaluation of Post-Closure Care (EPCC) Methodology in Europe. The EPCC Methodology was developed by Geosyntec to evaluate optimizing and ending PCC at MSW landfills regulated under RCRA Subtitle D in the U.S. Procedurally, the methodology is based on assessment that a closed landfill that no longer represents a threat to human health and the environment. Assessing landfill monitoring and management requirements in terms of maintaining functional stability allows care activities to be progressively reduced until no active care is necessary and only de minimus custodial care activities remain for passive control systems (mainly for the cover).

Risk Assessment of Potential Subsurface Vapor Intrusion Adjacent to a Manufacturing Plant in the United Kingdom

2026-04-02T16:45:48-06:00October 29th, 2009|Tags: , |

A former chemical manufacturing plant in the United Kingdom was scheduled for closure in the mid-1990s, and a team of environmental managers established a program for identifying and mitigating any potentially unacceptable risks to human health and the environment associated with the facility's 160 years of operation. During an initial screening of potential exposure pathways, subsurface vapor intrusion was identified as a possible concern. Residential properties are present in very close proximity to two former sandstone quarries that had been filled with waste materials and lime slurry from former chlorinated solvent production processes.

Remedial Action Plan for a Nuclear Licensed Facility in United Kingdom

2026-04-02T16:45:50-06:00February 23rd, 2008|

Geosyntec Consultants (Geosyntec) U.K. office (previously Ford Consulting Group) was retained to provide peer review and direction of a retained consultant’s work in relation to an assessment of contaminated land liabilities at an 88Ha facility. The subject site has a 60-year history of industrial use. It was initially developed to produce chemical munitions during WWII. It has subsequently been used to develop and manufacture fuel rods for the nuclear power generation industry. The overall aim of the project was to identify the scale and approximate cost of contaminated land liabilities at the site in line with the requirements of the UK Nuclear Decommissioning Agency.
