Grand River Aseptic Manufacturing (GRAM) Plant
Project Details:
Owner: Grand River Aseptic Manufacturing
General Contractor: CRB
Dates of Work: 02/2019 to 03/2019
Engineer: Engineering Design Solutions (Structural) and Materials Testing Consultants (Geotechnical)
Approximate Key Quantities: Controlled Modulus Columns (CMC)® rigid inclusions - 681 EA.
Project Overview:
proposed the construction of a two-story, 60,000 sq-ft facility equipped with industry leading technologies that support projects using high-speed, state-of-the-art manufacturing and packaging equipment. The new largescale, fill-finish facility would accommodate customer and industry-wide demand for Current Good Manufacturing Practice regulations parenteral drug manufacturing, analytical testing and regulatory filling services.
Ground Conditions:
Solution:
Micropiles were originally considered for foundation support. However, the owner sought a second opinion and the geotechnical engineer, Material Testing Consultants (MTC), contacted Menard and its sister company Nicholson Construction Company (NCC) about a CMC and low mobility grouting (LMG) solution. (MTC had worked previously with the companies on two projects close to the Grand Rapids site). This alternate solution proved to be both economical and time saving for the owner.
NCC performed LMG to fill voids at select locations across the site within the weathered bedrock. This technique is proven to prevent further void development and settlement in the Grand Rapids area. Menard installed CMC rigid inclusions that terminated in the dense sand layer that was present above the weathered bedrock. This combined design of CMC rigid inclusions and LMG was not only more economical than a deep foundation system that would have extended into the bedrock, but also offered substantial savings in the foundation itself by allowing the client to eliminate grade beams, pile caps, and structural slabs and utilize shallow foundations. Menard’s solution included the use of 681 CMCs that were installed beneath the spread and strip footings to a maximum depth of 60 ft. The design provided for 1 in of post-construction settlement with less than a ½-in of differential settlement, meeting the performance criteria for the new building.
