PEA Group led the site design and engineering efforts for the renovation and expansion of the Fiat Chrysler Automotive (FCA) facility on Detroit’s east side. This new development is a first for FCA in almost three decades, making them the only automaker to have an assembly plant located entirely within in city limits of Detroit.
The project included the renovation of two existing automotive plants totaling over 1,900,000 square feet of building floor area on nearly 108-acres in Detroit. The construction will include a new 358,000 square foot paint shop building with utility trestle connections to the existing plants. Other building additions and modifications were a new enclosed test track building, new and renovated guardhouses, upgrades to the on-site wastewater treatment plant, fire tank, and pump house.
The site improvements included modifications and expansion of existing parking lots, truck docks, railyard areas, truck, and employee gate entrances, storage tanks, pump and water reuse systems, fire protection systems, sewer systems, security fencing, turnstiles, and gates, as well as stormwater management and landscaping improvements throughout the site. Additional off-site trailer marshaling lots and other finish vehicle parking lots are included in the design scope for a total area of approximately 180-acres.
PEA Group performed multiple geotechnical investigations totaling 1,900 linear feet of drilling and 20 pavement cores. Our team provided recommendations and analyses related to shallow and deep foundations, foundation settlement, earth retention walls, pavement design, and subgrade evaluations. PEA Group also provided construction materials testing services for the FCA Mack S8 parking lot, including subgrade evaluations, base aggregate density testing, and casting over 1,200 concrete cylinders.
PEA Group also assisted FCA and the City of Detroit in the development of a series of neighborhood vignettes that studied the visual impacts of the proposed facility on the existing neighborhood and made design recommendations to mitigate these impacts through landscape planting, art installation, and green stormwater features as public amenities.
