MEETING DATE: October 5, 2009 AGENDA ITEM TYPE: Consent Agenda RECOMMENDATION: Authorize the City Manager to sign Change Order #3 for the Landfill Building Addition. The result of this change order will be an increase to the project in the amount of $3,919.12. Authorize the City Manager to sign Change Order #4 for the Landfill Building Addition. This change order is to add additional services to the existing contract in the amount of $2,236.60. The work included in this change order is to add finish taping and paint to the required fire protection and fire rating between the new addition and the existing garage. The paint will provide protection to the installed drywall when vehicles and equipment are washed down in the garage so that the water does not deteriorate the drywall. BACKGROUND: Change Order #3 includes four items; CP#5002 is for the addition of 2 smoke and fire dampers between the existing offices and the new garage. During the plan review process, which was done concurrent with bidding, the Building Department called out the need for smoke and fire breaks between the new addition and the existing parts of the existing building. The dampers were needed because of the total square footage of the old and new addition. The price for the two dampers, labor, equipment, and materials to install is $1,611.20. CP#5008 is for the modification and relocation of the walls in the locker room. During the early design stages for the project, a clear description of the peak use times of the locker room area was not outlined for the design team. Once the walls were framed up, it was clear that the area would not accommodate the full crew, lockers, and changing benches. This change allowed the square footage of the locker room to be increased and some of the hallways reduced. Because the change was initiated when only the walls were framed in and no other services or utilities installed the cost for the revision is $677.60. 36 CP#5011 is a change to accommodate snow loads on the site. The roof of the building is a metal roof. Snow accumulation on a metal roof often results in a sudden release of snow off the roof. The sudden release of snow is both a safety concern and a maintenance concern. In talking with the landfill staff, they pointed out that the orientation of the building and the weather conditions have yielding snow problems in the past. Because the total square footage of the roof area is increasing with the addition, snow cleats were added to the roof. These cleats provide enough holding power that the snow will not slide off in one giant cascade. In anticipation of the slow melt of snow and the freeze and thaw cycles of the accumulated snow, an outlet was added so that if ice damning becomes a problem heat tape can be installed in the gutters and down spouts. The cost for these pro-active maintenance items is $1,370.62. CP#5012 is also related to the modifications of the locker room. The IT closet area was reduced in order to provide additional square footage for the locker room. The reduction required the addition of another light fixture. The reduction of space required a smaller fixture so that there was space for both the light and exhaust fan in the IT closet. A combined light and fan unit was installed with credit provided for the fan that was already scheduled to be installed. The fixture and additional wiring amounted to $259.70. Total cost for Change Order #3 is $3,919.12. Change Order #4 is an increase in the scope of the project. Change order number #2 addressed the addition of sheet rock as a cost effective fire break for the urethane foam insulation that was sprayed on in the old garage area. The installed sheet rock was originally priced out to be fire taped. Fire taping is a cost saving measure often used in utility areas where appearance is not a problem. The seams of the sheet rock are taped and only one coat of drywall mud is applied to the tape and fasteners. This technique leaves large areas of the sheet rock exposed. The exposed surface is the paper covering over the gypsum material. The landfill crew has identified the exposed paper as a problem. The crews often wash down equipment and vehicles in the garage. If the exposed paper is sprayed with water it will deteriorate. This added change will fully bed the seam tape and fill in all the fastener holes. A coat of primer and two coats of finish paint will be applied to protect the new sheet rock wall. The cost for this additional work is $2,236.60. Total cost for Change Order #4 is $2,236.60. FISCAL EFFECTS: Change Order #3 is an increase in the cost of the project. The change will be charged against the contingency account which stands as follows; Project Contingency $27,361.85 (following CO#1) Change order #3 – 5002 ($1,611.20) Smoke/Fire Dampers Change order #3 – 5008 ($677.60) Locker Room Changes Change order #3 – 5011 ($1,370.62) Snow Cleats and Heat Tape Outlet Change order #3 – 5012 ($259.70) Electrical Changes in IT Closet Project Contingency Remaining $23,442.73 37 Change Order #4 for painting the fire-rated protection wall used to cover the urethane insulation in the garage will be paid for from the same account used to construction the wall – the Solid Waste Fund cash reserves. Addressing the urethane insulation was projected to cost $80,000. Budgeted Solid Waste Fund Cash Reserves $80,000,00 Change order #2 ($21,067.50) Fireproof Spray Change order #2 ($3,691.52) Gypsum Board Wall Change order #4 ($2,236.60) Finish Tape and Paint Wall Project Reserves Remaining $53,004.38 ALTERNATIVES: As suggested by the City Commission.
