Resolution No. 22-R-0031 — Change Order No. 1 — Berglund Construction Company for the Masonry Rehabilitation Project at 200 Main Street STAFF REVIEW: Mehul Patel, P.E., CFM, Director of Public Works SIGNATURE. Mii APPROVED BY CITY ADMINISTRATOR: Michael L. Guttman COMMITTEE AGENDA DATE: June 2, 2022 COUNCIL AGENDA DATE: June 6, 2022 SIGNATURE ITEM SUMMARY: The City owns the four-story masonry building built in approximately 1880 located at 200 Main Street. The primary entrance to the ground floor is from Main Street while a secondary entrance to the lower level is from Turner Court. This building is currently vacant. It was previously used as a mixed use building with commercial on the lower level and ground floor, while the second and third stories of the building were used as residential. In 2015, the City hired Matocha Associates, an architectural firm, alongside Tassone Architects, masonry architectural firm, and Structural Resources, Inc. (SRI), a structural engineering firm, to evaluate the deteriorating conditions of the building. These evaluations determined multiple issues with the building including, but not limited to, deteriorating masonry facade, structural building settlement, non-compliance with current American Disability Act (ADA) requirements, fire escape related non-compliance, leaking pipes, asbestos, roof damages, etc. All of these concerns were expected due to the age of the building. Since then, the City has removed all the piping in the building as well as all of the asbestos. This project has sat idle for the last couple of years. The City revived this project in recent months by awarding design contracts to the architectural firm, masonry architectural firm, and structural engineering firm to complete their respective designs for roof replacement, masonry rehabilitation, and structural rehabilitation. On December 21, 2021, the City Council approved resolution 21-R-0104 authorizing the Mayor to award a construction Contract for base bid alternate one, three, four, five, and six to Berglund Construction Company of Chicago, Illinois, in an amount $303,900.00 along with unit prices for certain items, for the Masonry Rehabilitation Project at 200 Main Street. The scope of work for base bid is including, but not limited to, tuck pointing, repair mortar joints, repair masonry stress cracks, remove and replace chimney masonry crown cap, remove and replace stone sill, remove and replace stone parapet cap, clean exposed masonry surfaces, and discard and legally dispose waste materials. The project included multiple alternate bids. ALTERNATE ONE: The level one (Main Street grade) original masonry arches (four) that have been removed should be replaced with window arch headers. The existing exterior window head is a curved masonry segmental arch with two rowlock header courses. ALTERNATE TWO: The level one stone veneer storefronts are not original and should be removed and replaced with a historic appropriate masonry style fagade. This item was eliminated from the bidding as the storefront entrance is likely to change when architectural improvements will take place in near future. ALTERNATE THREE: The south elevation, floor three (west end) replacement window was infilled with masonry and should be removed. ===== PDF PAGE 39 ===== [Extraction: OCR (rendered-page OCR)] CITY OF WEST CHICAGO ALTERNATE FOUR: The basement level interior (Turner Court), north, south, and east elevation existing stone walls will require that the joints be ground out 100%, stabilized, and the stone walls be pointed 100%. ALTERNATE FIVE: The basement level interior (Turner Court), south, and east elevations existing stone walls will require stabilization, and one wythe (layer of brick) of common brick to be installed (full height) in front of the existing stone walls.
