Abstract: A modular building structure for a turbomachinery equipment includes a first prefabricated structure, a second prefabricated structure, and a plurality of guides to align and couple the first prefabricated structure to the second prefabricated structure. The first prefabricated structure includes a first rigid frame formed from first linear members, and defines first pin receiving holes. The second prefabricated structure includes a second rigid frame formed from second linear members, and defines second pin receiving holes. Each guide includes a plate having an opening extending through the plate, and an elongated member extending through the opening of the plate. The elongated member includes a first end portion extending inside a corresponding first pin receiving hole and a second end portion extending inside a corresponding second pin receiving hole for coupling the first prefabricated structure with the second prefabricated structure.

Abstract: A building structure for operating turbomachinery equipment is disclosed. The building structure includes a first pre-fabricated structure, a second pre-fabricated structure, and a connector attaching the first pre-fabricated substructure to the second pre-fabricated substructure. Each pre-fabricated substructure includes a rigid frame formed from a plurality of linear members. The plurality of linear members forms a first rectangular structure, a second rectangular structure, and connects the first rectangular structure to the second rectangular structure. Each pre-fabricated substructure also includes a noise attenuating sealing panel attached to one or more of the first rectangular structure and the second rectangular structure. The connector includes a spacer plate inserted between first and second pre-fabricated substructures and a fastener. The spacer plate includes an elongated opening extending through the spacer plate.
