RECOMMENDATION City Manager approve Change Order Number Two which will increase the contract for the 2009 Affordable Housing Roof Repair Project. The budget for this contract is $205,512.00 including $50,000.00 for the contingency and $30,000.00 for staff time. With the approval of this change order the contract amount becomes $156,832.00. The attached change order resulted from the need to enclose the new roof extensions in the same manner as the existing construction with fascia and soffit to match. The additional work will provide the facility with a weatherproof roof structure that will perform in the same manner as the existing roof and provide the additional safety benefits for which this project was designed. The fascia and soffit at the new roof extensions were not considered during the original design of the roof repairs and none of the potential bidders raised the question during the bidding process.

RECOMMENDATION Staffs recommends that the City Manager approve Change Order Number Five which will increase the contract for the 2009 Affordable Housing Roof Repair Project. The budget for this project is $267,500.00 including: $125,512.00 for the base contract with Chopu Construction, $141,820.00 for previously approved change orders and $30,000 for work associated with Change Order #5. With the approval of this change order, the contract with Chopu Construction becomes $297,500.00. DISCUSSION The attached change order resulted from roof leaks that appeared during the winter of 2009/2010. This change order is proposed to address leaks at Bldg C and Bldg A of the Annie Mitchell housing complex. The City's consulting engineer for the Annie Mitchell Snow Fence project, Wiss, Janney, Elstner was employed to investigate the source of the leaks and develop recommendations to address the problems. The Bldg C leak is indirectly related to the snow fence installation project. Last winter saw an unusual amount of freeze /thaw cycles. That coupled with the snow fence acting, as it was designed, to hold the snow on the roof resulted in an ice dam building up at the low edge of the roof. As snow from above melted, it ran down the roof until the ice dam prevented the liquid from shedding off the roof and caused the water to back up into the building. In order to properly address this leak, it has been recommended to remove the existing metal roofing panels and sheathing, determine source of leak and address as needed. The sheathing will then be replaced, new ice and water shield roofing membrane installed along with appropriate flashing around an existing skylight and at the low edge of the roof. The metal panels will then be reinstalled and heat tape will be placed at the roof edge, around the sky light and into the gutters so that liquid water can drain from the roof. The Bldg A leak has been an ongoing issue since the project was completed. It has been traced back to insufficient weatherproofing above the unit that has been affected. According to the consultant's investigation, proper flashing between the green roof plaza and the vertical elements of the structure were never installed. In order to address this issue, part of the concrete slab at the green roof will need to be removed along with some of the siding at the vertical surfaces of the building. Appropriate flashing , waterproofing membrane, drainage mat and sealant will then be installed per the consultant's recommendations. Upon passing a flood test the concrete, metal decking, siding, landscaping and any other elements disrupted by this work will be replaced.

Galena Street Aspen, Colorado 81611 Re: Annie Mitchell Unit 103 Leak Aspen, Colorado WJE No. 2010.1839 Dear Mr. Rourke: Per your request, Wiss, Janney, Elstner Associates Inc. (WJE) visited the Annie Mitchell condominium complex located in Aspen, Colorado. The purpose of this visit was to perform an investigation of the plaza waterproofing above Unit 103 to determine the source of the reported leak. Based on our findings and at your request, we have outlined a recommended scope of work for repair of this issue. OVERVIEW The multi -unit complex, comprised of condominium buildings and a plaza area, is mostly constructed over a parking structure. The waterproofing is a self - adhering membrane adhered to the substrate. Reportedly, water was observed at the ceiling of the Unit 103 hallway between the bedroom and bathroom during rains. This unit is located at the lower level at the north end of the complex. OBSERVATIONS During our visit, no visible signs of leakage or stains were observed on the ceiling (Figure 1). However, we did observe that a fire sprinkler head in the bedroom was dripping (Figure 2). Water testing was performed on the lower walkway (directly above the unit) for a total duration of approximately 40 minutes focusing mostly on the walls and parking garage door threshold (Figure 3). The west wall of the walkway is the exterior wall of the unit above 103. This wall is situated over the hallway in Unit 103. No visible signs of water were observed inside the unit below following the water testing.

Missing flashing at top of walkway ledger at concrete WJ E ENGINEERS Mr. Shaun Rourke ARCHITECTS City of Aspen MATERIA1S SCIENTISTS July 22, 2010 Page e 2 2 Further investigation was performed at the walkway two levels above Unit 103. We observed the following conditions at this level: • The perforated metal plank walkway transitions to a plaza area, consisting of sidewalks, patios, and landscaped areas, located over the top of the parking garage (Figure 4). A wall with an entry door to the parking garage is located below this transition with a ledge at the top that supports wood beams for the metal plank walkway (Figure 5). • When some of the metal planks were removed along the west wall of the walkway, the exterior sheathing was visible behind and above the ledger board (Figures 6 - 7). Typically, a metal flashing is installed above the ledger that extends up behind the siding and weather resistive barrier to direct water over the ledger. With the flashing missing, water can run down behind the ledger, behind the weather resistive barrier and into the unit two levels below. • The end of the walkway ledger meets the edge of the topping slab (Figure 8). A sheet metal flashing was installed over the ledge at the top of the wall and extends up over part of the end of the concrete topping slab (Figure 9). Failed sealant was observed at the top of this flashing. • When the vertical flange of the sheet metal flashing was pulled back, the waterproofing membrane between the structural slab and topping slab was visible (Figure 10). Waterproofing membrane installed at the ledge extended up to the horizontal waterproofing between the structural and topping slabs. The top edge of the ledge waterproofing membrane was open at the top in several locations allowing water coming off the surface and from below the topping slab to run behind this waterproofing and into the wall. • At the request of WJE, the contractor removed a portion of the existing topping slab to expose the existing waterproofing membrane. The waterproofing membrane was identified as Grace Bituthene. A drainage mat was also observed over the waterproofing membrane. RECOMMENDATIONS I SCOPE OF REPAIR Based on our observations, the installation of the flashings and waterproofing were not completed and in some instances poorly executed during original construction. Several avenues or areas were observed that will allow water into the walls and down to the unit below. We recommend the following repairs at the upper level walkway and plaza waterproofing: • At the ledgers (both sides) of the metal plank walkway, we recommend removing the lower course of siding to access the ledger and weather resistive barrier (Tyvek). Install new 24 ga. galvanized flashing at the ledger (Detail WP4). Seal all laps in the flashing with silicone sealant. The existing weather resistive barrier must lap over the vertical flange of the new flashing. Reinstall the existing siding or replace if damaged. • Remove the entire concrete topping slab, portion of the sideway, and portions of the landscaping located over the entry to the parking garage to access the existing waterproofing (see Limits of Repair on Sheet WP I). .................. ................. .................. . ................. .......... ..........

(WJE) visited the Annie Mitchell condominium complex located in Aspen, Colorado. The purpose of this visit was to perform an investigation of the roofing to determine the source of two roof leaks that occurred at Unit 620 this past winter. Based on our findings, we have outlined below our recommendations for repair of this issue. OVERVIEW The multi -unit complex, comprised of condominium buildings and a plaza area, is constructed mostly over a parking structure. The 2:12 and 12:12 steep sloped roofs (Figure 1) consist of 5V pre- finished metal roof panels secured with screws (with rubber washers) over a self- adhered underlayment adhered to wood sheathing. The roof structure has a traditional attic space that is vented at the eave soffits and at gable vents at the gabled roofs or, at mono - sloped roofs, a continuous vent at the high soffits. WJE provided repair recommendations regarding snow management and those recommendations have been implemented at the project. Reportedly, two leaks have occurred at Unit 620 during this past winter: one above the door to the balcony deck and one near the skylight. Photographs provided by the City of Aspen indicate that significant ice conditions occurred near the cave edge of the roof above this unit. OBSERVATIONS Two leak areas were reported at Unit 620: One above the swing door to the balcony deck (Figure 2) and one near the skylight (Figure 3). Observations were performed in the attic but were limited due to the placement of a girder truss located approximately 6 feet back from the exterior wall. No visible signs of condensation were observed indicating the attic is adequately ventilated to prevent such a condition (Figure 4). Approximately 18 to 20 inches of blown insulation was placed above the ceiling in the attic (Figure 5). Baffles were provided at the lower portion of the roof to prevent the insulation from blocking the air passage at the eaves of the roof and these appeared to be open (Figure 6).

At this location, the edge of the Grace Ultra, installed as part of the snow fence installation, was lapped over the existing Grace Ice and Water Shield (Figure 8). Ice and Water Shield was installed over the horizontal flange of the cave and rake edge flashings. However, no Ice and Water Shield extended down behind the gutter. A roof panel was removed along the side of the skylight to observe the skylight flashing and underlayment (Figure 9). Accumulated dirt under the panel and on the surface of the Ice and Water Shield indicate that water has been under the panel at this location (Figure 10). No visible deficiencies were observed in the exposed Ice and Water Shield near the skylight. DISCUSSION In our opinion, the 5V metal panels installed on the 2:12 slopes are not suited for such a low slope and winter weather conditions in this area. The panels have low ribs and are not sealed where the panel joints overlap which make it more susceptible for water to get under the metal panels. A mechanically seamed standing seam metal roof system would be better suited for these roofs. Based on our observations and discussions on site, we believe the leak at the head of the balcony door is a result of excessive ice accumulation at and near the cave edge. It appears the formation of ice is caused by water freezing at the gutter located between the balcony roofs. As the ice continues to build, it can push up under the cave and rake flashing and into the soffit and attic (Figure I]). In addition to repairs to the roofing, the installation of heat cable will be necessary along the cave edges, gutters, and downspouts to manage the ice issues occurring at this location. RECOMMENDATIONS We recommend the following repair: • Remove the existing roof panels to expose the underlayment from 4ft. east of the east skylight to 4 ft west of the west skylight (as shown on roof plan below). Demolition Plan (Remove panels at shaded area) t/ j i ENGINEERS W1 ARCHITECTS MATERIALS SCIENTISTS Mr. Shaun Rourke City of Aspen July 19, 2010 Page 3 Remove the existing gutter, edge metal between the balcony roofs, portions of the eave metal at the balcony roofs. Remove the existing flashing from around each of the skylights. • Remove a sheet of the existing plywood sheathing over the leak area above the door to verify the source of the leak and reinstall. • Remove all loose and non - adhered existing Ice and Water Shield. • Clean (and prime as necessary) the existing Ice and Water Shield to remain to achieve full adhesion of the new Grace Ultra. • Install a new 18 inch wide strip of Grace Ultra extending 3 inches over the edge onto the face of the fascia at the eave and rake edges. Install new edge metal at eave and rake edges and gutter as shown in the details below. NEW GRACE ULTRA. LAP OVER NEW EDGE METAL 10' GRACE ULTRA. EXTEND OVER EDGE T NEW 24 GA.

Seal the edges of the new Grace Ultra where it ends at the existing Ice and Water Shield with Grace Mastic. • Reinstall the snow fence flashing (if not damaged) as specified in the drawings provided during the snow fence installation. • Remove loose and canted existing Ice and Water Shield around both skylights. Apply a cove bead of Grace Liquid Membrane at the base of skylight curbs. Install new Grace Ultra extending to the top of the existing skylight curbs. Apply Grace Mastic at all laps and corners. Install new 24 ga. pre - finished metal flashing at the perimeter of the skylights integrating properly with the metal roof panels. Provide a "J" strip along the raw edges of the panels along the sides of the skylights. • Re- install the metal panels, replace if damaged. At all reinstalled panels, install butyl tape at the vertical laps. • Following the completion of the installation of the metal panels, install new heat cable at the eave edges of the balcony roofs and at the eave edge between the balcony roofs. The heat cable should be installed in loops 12 inches on center, loop into the gutter 3 inches, and extend up the roof slope 24 inches past the exterior wall. Install two lines of cables in the bottom of the gutter and completely down through the downspout. Install new electrical circuits as necessary to operate system.
