McGuire Engineers, Inc. was hired by 601W Companies in 2015 and has been responsible for the complete renovation of all MEP/FP and Technology infrastructure for the building.  McGuire Engineers provided MEP & FP Engineering Services for the 2.7 million SF of new Class A office space at 433 West Van Buren. One of the first of many projects McGuire Engineers was tasked with was the replacement of the train track exhaust fans and the establishment of temporary to permanent electrical service of the entire facility. In order to accomplish these tasks efficiently and to minimize future rework, McGuire Engineers initiated a brief master planning effort to identify high level cost and space impacts for future mechanical and electrical services and distribution paths. 


McGuire Engineers has also led the effort to coordinate all new utility services including gas, water, sewer, power and telecom. In addition to the many challenges that arise for renovation project of old buildings, this project also has the added complexity of the building being above Amtrak train lines and being a Landmark Building, which requires addition-al approvals from both Amtrak and IHPA (Illinois Historical Preservation Association). Despite all of the many challenges, McGuire Engineers was able to deliver a coordinated MEP design for a very aggressive construction schedule. 


At the Old Post Office (OPO), the Owners intended to use the rooftop as the amenity deck leaving limited space for dedicated outside air units.  MEPC designed around difficult geometries within the building’s Pylons to locate the Dedicated Outside Air Systems (DOAS) units which supply ventilation to the entire building.  Additional construction constraints include working within the existing Compressor building which housed original chillers that would be converted into a new plant for Enwave.  The compressor building had a sloping deck and many large columns.  In both scenarios, McGuire Engineers took detailed surveys of the existing conditions noting the size of columns, and floor-to-floor heights in various locations.  We also took detailed notes about the existing opening locations for ventilation air (DOAS) and river water access (Enwave Plant).  We developed a detailed set of drawings utilizing plan views as well as elevation and section views of the existing conditions with new (large) equipment, piping, ductwork, etc. A true testament to quality drawings is when the Contractor chooses to install the equipment and piping in a (close to) identical fashion.
