PROJECT WORK
GEOTECHNICAL
Geotechnical Investigation, Halifax Water
Meco was retained by Halifax Water to complete a Geotechnical Investigation to support design development for a commercial building and parking area at Shearwater Air Force Base, Halifax, NS.
Halifax Water was the prime contractor to Defence Construction Canada (DCC) for design of the building and related infrastructure and required Meco to design and manage the geotechnical testing and sampling for the building area and civil design features.
The work consisted of a borehole investigation for the building and test pit investigation for the parking area and civil infrastructure.
Meco responsibilities included:
- Project management and procurement of contractors for site clearances, drill plant, and materials testing.
- Technical planning and layout of the target drilling program to achieve the client-defined objectives.
- Prepared a detailed Health, Safety and Environment (HSE) protection plan prior to the start of work, and implemented the plan during execution of the work.
- Full-time field supervision during execution of the investigation program, stewartship of sample collection and testing, and preparation of detailed daily reports.
- Prepared a detailed geotechnical investigation interpretive report on the observed conditions during drilling, an opinion of the geological model and assessment of how to proceed with the project.
Meco completed the investigation within the schedule window established at project initiation. Deliverables from Meco included a comprehensive HSE document prior to the investigation, an interpretive geotechnical report and effective project management of services. Meco worked closely with the C-Core and Husky to ensure a proper handshake at the thimble, and cooperation with contractors.
Dam Foundation - Investigation, Halifax Water, Lake Major
Meco was retained by Halifax Water to complete a Geotechnical Investigation to support design development for the Lake Major replacement dam, Halifax, NS.
The field investigation program was carried out in three (3) phases and consisted of fourteen (14) boreholes and five (5) test pits. Three (3) of the boreholes were drilled from a barge directly on the reservoir. The field investigation included soil sampling, rock coring, and in-situ permeability testing of the bedrock.
Since Lake Major is a water supply for the Dartmouth area, special attention was required to mitigate the environmental risks related to water quality of the reservoir.
Meco responsibilities included:
- Project management and procurement of contractors for site clearances, drill plant, and materials testing.
- Technical planning and layout of the target drilling program to achieve the client-defined objectives.
- Prepared a detailed Health, Safety and Environment (HSE) protection plan prior to start of work and implemented the plan during execution of the work.
- Full-time field supervision during execution of the investigation program, stewartship of sample collection and testing, and preparation of detailed daily reports.
- Prepared a detailed geotechnical investigation interpretive report on the observed conditions during drilling, an opinion of the geological model and assessment of how to proceed with the project.
The investigation and subsequent reporting were completed on schedule, within budget, and to the satisfaction of Halifax Water. The information obtained from the geotechnical investigation was later used by Meco in developing an innovative detailed engineering design for the replacement dam.
