May 20, 2013 Mr. Richard Schleyer Public Building Commission of Chicago Richard J. Daley Center, Room 200 50 West Washington Street Chicago, Illinois 60602 Re: Hazardous Material Survey PBCC Project # 18670 Charles G. Hammond Elementary School

2819 W. 21st Place Chicago, IL 60623

Dear Mr. Schleyer: Carnow, Conibear & Assoc., Ltd. (Carnow Conibear) was retained by the Public Building Commission of Chicago (PBCC) to perform a hazardous material survey prior to renovations at Charles G. Hammond Elementary School in Chicago, Illinois. The survey was limited to materials and areas which could be disturbed during planned renovation activities. The list of the proposed renovations was provided on the design architectural scope sheets and cost estimate from the PBCC, attached. Carnow Conibear reviewed the renovation items prior to the survey to determine which areas of the school may be affected by the renovation activities. The hazardous materials survey was conducted on May 14, 2013 and consisted of visually inspecting the school building proposed renovation areas to determine the presence and location of polychlorinated-biphenyl (PCB) containing equipment (lighting ballasts, switchgears, transformers, and hydraulic fluids), mercury-containing equipment (mercury lamps, thermostats, switches, thermometers, regulators, and gauges), and other hazardous chemical wastes, such as chlorofluorocarbons (CFCs) or equipment. All items listed were assumed to contain the related hazardous materials since no sampling or internal investigatory inspection of electrical or other equipment was performed as part of the survey. Based upon the survey and limitations of the scope sheets, Carnow Conibear identified the following materials that will require special handling during their removal as part of the renovation work.

Mr. Richard Schleyer Hazardous Material Survey Charles G. Hammond Elementary School May 20, 2013 Chicago, IL 60623

Carnow Conibear did not include the movable equipment, computers, and other class room supplies or equipment. Carnow Conibear understands that these items will be relocated out of renovation areas as deemed necessary by the Chicago Public Schools. Since the renovation scopes do not include the details of the final design and all potential areas that could be affected by the future Design Builders work, Carnow Conibear has included the following list of materials commonly located in areas of the school.

Table II: Common Hazardous Materials - Schools

Category Item

PCBs Fluorescent Ballasts Hydraulic Lifts/Elevators Hydraulic Oil Tank

Chemicals

Boiler Chemicals Cleaning Chemicals Fire Extinguishers Paint Science/Laboratory Chemicals Art Supplies

CFCs

Other Batteries/Emergency & Exit Lights Computers/Other Electronics

Carnow Conibear recommends the following:

Incorporate data from this report into the design and renovation documents. Identify all hazardous materials requiring removal/handling within the final design

renovation scope. Include additional items from Table II as applicable. Perform internal inspections and sampling of all materials requiring removal to ensure

proper characterization of waste materials. Coordinate inspection of electrical equipment with a licensed electrician. Properly dispose of all materials which are removed as part of renovation work in

accordance with local, state and federal, regulations. Properly document the handling and disposal of all wastes generated as part of

renovation work.

Incidental MEP-FP Notes

One of (2) condensing units serving the building addition is non-operable. There is currently a work-order for it, but it is non-functional.

DDC temperature controls are not functioning correctly. Incorrect readings and equipment feedback. System dates back to early 90's.Steam piping is not insulated in boiler room and heat loss to space is substantial.AHU serving addition is single zone; but serves multiple spaces. Temperature control in spaces is poor per staff.AHU-1 (main building) has a small coil leak that is behind the sheet metal blank-off panel.

Steam traps have failed throughout the building and steam is flowing in the condensate return system creating heat problems at equipment.3rd floor boys toilet in the Main Building has a missing lav.Water pressure throughout building is poor.
