Due to the fact that the two remaining areas of the City Hall have been leaking ever since the building was built almost three years ago, and the failure of the contractor to make thc correct necessary repairs, staff recommends the City obtain a special testing/inspcction company to conduct water leak testing to first, substantiate that the areas in question do in fact leak (recommended procedure for arbitration), do destructive investigation (remove stone and building materials), to determine the exact cause of the leak, and finally prepare a report detailing the water tcsting procedure, findings, and cause of the Icaks, and to makc recommendations on how best to repair thc leaks. Staff has received two quotes from companics that specialize in the above proccdures. Those companies are "Inspec" and "Architectural Tcsting." Both companies quoted a "not to excecd" t . e -
