GENERAL BACKGROUND:
Mr. Grenier is a Geotechnical Engineer supporting our Chief and Principal Engineers on a variety of geotechnical projects. Mr. Grenier's project contributions have included in-field geotechnical assessment and observation, and exploration and sampling of test borings and test pits for geotechnical pre-construction engineering analyses and design. He performs project tasks such as collection of soil samples, determination of in-situ strength of cohesive soils, and performance of laboratory consolidation testing. Mr. Grenier's duties also include the assignment of laboratory testing necessary for geotechnical evaluation of project sites, along with geotechnical engineering analyses, including settlement evaluations and deep foundations, and design and technical report preparation. Projects on which Mr. Grenier has prepared design and technical reports include, but are not limited to, utility projects, airports, retail developments, hospital additions, schools, self-supported and guyed towers, municipal buildings, and marine research facility. Mr. Grenier also performs construction monitoring duties such as observation of pile driving, removal and replacement of unsuitable foundation bearing material, and installation and proof-testing of rock anchors.
Prior to joining RWG&A, Mr. Grenier held the position of Project Engineer at a geotechnical engineering firm in Georgia. While there, he worked on a variety of projects providing both geotechnical design and construction observation services. Design project tasks included subsurface soil stratification, collection of soil samples, geotechnical engineering analyses, and design and technical report preparation. Construction observation services included observation of deep foundation installation including driven and auger cast piles, monitoring of pile load tests, shallow foundation and slab/pavement subgrade inspections, subgrade stabilization, construction monitoring for Category I (High Hazzard) and Category II earthen dams, both new construction and dam rehabilitation, observation of installation of soil nails and associated shotcrete placement, and construction monitoring of rock drilling and blasting. Mr. Grenier also performed Phase I environmental site assessments, pavement design, and design and evaluation of modular block retaining walls.
REPRESENTATIVE EXPERIENCE:
Greenland Meadows - Greenland, New Hampshire Performed geotechnical design services for a new 600,000 square foot retail facility. Design services included monitoring of test pits and test borings, field infiltration testing, and technical report preparation. Construction phase services included pre-blast surveys, foundation subgrade observation, settlement platform measurements and evaluation, and observation of porous asphalt placement.
Tweed International Airport - New Haven, Connecticut Performed geotechnical design services for new safety areas and wetland mitigation sites. Design services included monitoring of test borings, field CBR testing, coordination with airport personnel, and technical report preparation.
University of New Hampshire, New Residence and Dining Halls - Durham, New Hampshire Performed construction observation and coordinated materials testing services for a six story Residence Hall and five story Dining Hall. Services included monitoring of driven piles, observation of removal of unsuitable soils, rock excavation, installation of steel sheet piles, rock anchors, and minipiles, and coordination of materials testing, including concrete, steel, soil, and weld inspections.
Center for Disease Control, Lab Building 103 - Chamblee, Georgia Performed construction observation and coordinated materials testing services for a five story lab building. Services included observation of more than 400 auger cast piles, performed four pile load tests, evaluated shallow foundation subgrades, coordinated concrete, steel, and soil testing at a secure site, and managed the materials testing budget.
Edie Creek Dam - Barnesville, Georgia Performed construction observation for the rehabilitation of a 2400 foot long, 35-foot tall Category II Dam damaged during the 1994 floods. Observation included foundation and fill subgrade evaluation, installation of toe, blanket, and chimney drains, placement of gabion wall and reno mattress spillway, installation of slurry cutoff wall, and rehabilitation of breach area which occurred during construction.
Fulton County Stockade - Atlanta, Georgia Performed geotechnical design services for several multi story prison structures, including two eight story towers. Design services included several alternative foundation designs, deep foundation and settlement analyses, coordination of drilling at a secure site, client meetings, and temporary underpinning analysis.
