LAKE El.MO, MINNESOTA 55042 <br /> <br />February 2, 2009 <br /> <br />Mr. Dan Van Bogart <br />Minnesota Renaissance School <br />1333 5th Avenue South <br />Anoka, MN 55303 <br /> <br />Re: Minnesota Renaissance School! Ramsey City Hall Building <br /> <br />Dear Mr. Van Bogart, <br /> <br />This report provides investigation findings and recommendations regarding Ramsey's former City Hall <br />and Police Department buildings located at 15153 Nowthen Blvd. It is my understanding that the <br />inspected buildings have been proposed as temporary facilities for the Minnesota Renaissance <br />School. The proposed building use would include approximately 12,800 square feet, including the <br />entire main level of the City Hall Build1ng and both levels of the Pollee Department Building. <br /> <br />My inspection of the City Hall Building revealed several conditions that are suggestive of prior water <br />damage and active moisture Intrusion. These conditions Include prior roof leaks, moisture intrusion <br />through foundation walls, moisture intrusion at above~grade walls, and plumbing failures. Sporadic <br />fungal contamination was observed at perimeter walls and ceilings. These conditions are discussed in <br />greater detail below. <br /> <br />Prior Roof Leaks: City Hall Building <br /> <br />The building has sustained prior water damage due to leaks in the original roof system. It is purported <br />that the roof was replaced in 1990; however, water~damaged materials within the roof and ceiling <br />assemblies were not remediated. Visible water damage such as staining and/or peeling paint occurs <br />on ceiling tiles, wood ceilings, and gypsum board ceilings. Suspected fungal contamination occurs on <br />damaged ceilings in common areas between the City Hall and Fire Department. The observed <br />conditions indicate a moderate to high likelihood of fungal contamination on concealed surfaces such <br />as gypsum board backing and framing members. <br /> <br />Foundation Walls: City Hall Building <br /> <br />The following conditions are suggestive of prior moisture intrusion and a high likelihood of sporadic <br />fungal contamination: <br /> <br />. Efflorescence (I.e, minerai deposits) occurs on interior surfaces of exposed foundation <br />walls. The observed conditions are Indicative of widespread moisture intrusion at all <br />below-grade walls. The concrete block walls are painted but do not contain additional <br />finished materials such as insulation and gypsum board. Although the efflorescence itself <br />poses no Immediate hazards, moisture sensitive materials such as paint, adjacent <br />gypsum board celling, and cabinets in direct contact with the foundation could harbor <br />fungal contamination. <br /> <br />Built Environments.
