1 Architectural Elements Building Envelope A. System Description 1. The main portion of the building has a standing seam/batten type roof. This is over wood sleepers which sit atop the metal decking, filled with R19 batt insulation. A vapor barrier is installed atop the metal decking at areas without the acoustic insulation. Above the pool and spectator areas, the metal roofing is also installed over the wood sleepers atop the metal decking. The decking spans over intermediate exposed wood glulam beams. The metal decking has a sprayed on acoustic finish. No vapor barrier is noted in these areas. 2. South and west sections of the roof are low slope, with modified bitumen roofing over rigid insulation over metal decking and steel bar joists. R19 batt insulation is installed below the metal deck. 3. Portions of the roof have kalwall translucent panels sloping to match metal roof slopes. These areas transition to vertical panels, both of which provide day lighting in the pool/spectator areas. 4. Exterior walls are brick veneer over concrete masonry units. At the north walls, the space between CMU and brick is filled with 1 ½ rigid insulation, leaving ½ airspace. Hollow cells of CMU are filled with vermiculite. Portions of the north wall have been rebuilt, to assure proper air space provided to allow the movement of vapor. 5. South facing non Trombe exterior walls and exterior stairwell walls are 4 brick veneer directly over the CMU. No air space or cavity insulation is provided. Hollow cells of the CMU are filled with vermiculite. 6. South facing Trombe walls have the kalwall panels installed over 4 airspace, over a 12 solid CMU mass wall. This appears to be a non-ventilated Trombe wall design. 7. Exterior walls generally have 1 rigid insulation to a depth of Operable steel sash windows are installed at the upper south wall, adjacent to the spectator area. B. System Conditions/Observations 1. The standing seam roof has been subject to problems in high wind situations. The battens have come loose. The underlying panel fasteners may have corroded over the years. Visual inspection of these is impossible, as they are concealed. Cap flashings are damaged. Several

2 sections of roof have blown off and been reinstalled and are now rippled and dented. Portions of the roof were replaced on the north side with non-matching color units. 2. The modified bitumen low slope roof areas have been reroofed and are in average condition. Vertical modified flashing is not fully adhered to the masonry. Surface mounted reglets need to be resealed. One roof drain filter basket is missing. 3. A precast wall coping element, above the Trombe wall sections is deteriorating. The protective coating is failing on the face and is cracked and allowing infiltration at the top. The metal coping atop the masonry sections is lacking screws and neoprene washers in some areas. 4. Sloping and vertical sections of the kalwall are discolored and highly deteriorated due to sun and climate exposure. The panels both leak and attract condensation on cold nights, which then drips during the days. The exterior has fiberglass bloom the exterior protective gel has worn off, exposing the underlying fiberglass. Light transparency is greatly reduced from its original form. 5. Flashing at the base of the kalwall sections allow water infiltration. 6. Water is infiltrating below the kalwall, atop the precast concrete sill, at the west exit stair. Light is visible where caulking has fallen out. The steel supporting the sloping kalwall is highly corroded. 7. Roof drainage behind the south entry and stair element, at the sloping kalwall, is non-existent and a persistent source of roof leakage. Crickets were apparently lacking in the original construction. 8. The low slope roofs above the mechanical areas are inaccessible, no roof ladder is provided for these higher roofs. 9. Glulam beams above the spectator area are showing signs of minor surface delamination. The ends of the same beams show extensive checking, where water vapor from the environment has infiltrated. 10. Some Glu-Lam columns, adjacent to the second floor operable windows, show signs of potentially major decay, where they have been exposed to repeated water infiltration. One section of kalwall has recently pulled away from the supporting column. 11. The structural lintel above the second floor foyer has a significant crack visible on the lower side. 12. At the north low roof, a gutter is coming apart at the seams. The downspouts on the north have been damage near the bottom outflow area. 13. The exterior precast element at the west stairwell is in poor condition. 14. Many areas of brick veneer are flaking off at the west and above the low slope roofs. 15. The brick veneer at the central stairwell corners and other wing wall conditions has been exposed to water infiltration and freezing conditions, causing crack and the veneer to separate from remainder of the wall.

3 16. The brick veneer at the north, which was replaced in a prior project is in generally good condition, though areas of this have efflorescence from the mortar staining the brick s face. 17. At the east wall, an electrical outlet is missing its cover, leaving the electrical device and cavity open to the elements. 18. The south facing lower vertical Trombe wall panels were recently replaced with a non-kalwall product (Major Industries?). These newer panel faces are already separating from their frames. Temperature extremes within the Trombe wall cavity may be causing this. 19. The operable awning windows in the spectator areas have failed insulated glass units, with condensation forming in the cavities. Hardware has also corroded. The building s main entry lacks security access control. C. Code / Life Safety Issues 1. The west, north and east building exits all have a step of 4 6 at the threshold. No transition is allowable at exits. 2. The building envelope, roof and walls, generally does not provide insulating values required by the Energy Code. D. Maintenance Issues 1. Most transitions between materials lack proper sealants or original sealants have long ago deteriorated. This is especially a problem at the sill conditions of the upper operable south facing windows. 2. Seals are missing from some of the exterior doors. 3. The southeast exit doors in the pool area have exposed wood shims at the jambs. The closer is highly corroded. E. Recommendations 1. The metal roof needs to be replaced. Additional roof insulation is needed and a new vapor retarder needs to be installed below the batt insulation, atop the exposed metal decking. 2. The low slope roof finish should be removed, with additional rigid insulation added, then a new single ply system installed. New copings and flashings need to be installed at these areas.

4 3. The kalwall day lighting system needs to be removed and replaced with new higher performing panels, or with metal roofing to replace the sloped kalwall systems, and new glazed walls to replace the vertical sections. 4. The Trombe wall should either be abandoned, with new brick veneer installed, or a new ventilated Trombe system installed, with new glass panels. 5. Photovoltaic system should be considered for the sloped metal roof areas. 6. Provide roof hatch and ladder for west roof, for safety and to improve maintenance. 7. Non insulated areas of the existing double wythe masonry walls should be furred and insulated. A water vapor should be installed at these walls, and failed exterior bricks replaced. Interior furring should water resistant. 8. Entire exterior sealants should be redone, masonry sealed and coatings replaced at precast elements. 9. The existing operable windows at the spectator areas need to be replaced.
