WCC0301 June 4,2004 Wayzata Country Club Addition/Renovation Page 3 r7it-D. Detail 6C: This may be subject to interpretation due to the wall "jog"adjacent to the door in this detail, but it does not appear to meet the 18 inch side clearance required by the MN Accessibility Code. Section 1341.0442, Subpart 6 requires a door to have no more than an 8 inch recess. MDA will shift the north bay areas of the room 2"south. This will alter the `jog"to a 7%"recess, therefore meeting the intent of the code. It will also create a plane difference or a step between the first and second floor, which is fine. As this is Alternate A2, no further details or modifications will be drawn until the alternate is accepted. o•kc- E. Details 1D and 1 E: Do these reception desks fall under the requirements of MN Accessibility Code Section 1341.0720, Subpart 1? If it is believed that they do not, has the City approved this design? Will there be other"desks"or similar in our scope of work that may need an accessible portion? These counters do not fall under the noted requirement since they are more a "security"counter than"assistance" counter. No comment has been made to date with preliminary code reviews by the City. Final code review by the City is pending. There are no other"desks"in this project, only two bars and two pieces of furniture used as host stations at the restaurants. 7. Sheet A330(Typical), also 5D/A650: What are the deflections that we should expect in the new construction? We like to check w/structural in order to provide the most efficient design of the fire stopping systems. Detail 5D/A650 indicates a typical wall joint in plan view. No substantial deflection is expected along wall panels. A detail similar to this showing the top of a stud wall meeting a precast plank structure should show a slip joint capable of allowing for 3A"max. vertical movement on this project. MDA to issue typical detail for clarification. 8. Sheet A331, Detail 2E and 1A/A350: How should the vapor barrier be maintained continuous at this section? This detail should be modified to show the vapor barrier continuing down past the floor on the south side of the laminated wood beam and under the 2X10 wood joists, until it connects with the vapor barrier that exists (hopefully) in the existing north wall of the Pro Shop. Batt insulation will be removed and rigid applied on the underside of the vapor barrier with plywood, metal lath and stucco finish. MDA to issue detail. 9. Sheet A380, Details 3D and 6D: Please clarify the extent of vapor barriers and/or waterproof membranes in these details. Please Note: Detail 2D/A382 indicates a typical detail with a vapor barrier continuous over the precast. This does not seem to be appropriate for 3D. If a vapor barrier is to be "exposed", does it need to be a Class I flamespread material? The vapor barrier at the `floor"level will continue from the roof area under the concrete topping and terminate at the wall assembly. The concrete topping will be considered more of a "walking"surface than a structural surface. The detail should be modified to cover waterproof membrane at the wall with gypsum board. This should eliminate any exposed material in this area. MDA to issue detail. 10. Sheet A381: A. Details 5B and 4E indicate that these spaces are vented per 4E/A382 and 5E/A382. Please clarify venting, insulation, vapor barrier and waterproof membrane. Modified details will be issued by MDA. B. Detail 6E: If this floor is a walking surface, should additional protection be provided at the edges or should the flooring be wider? The plywood"flooring"should extend to the walls of the "dormer". 11. Sheet A382: A. Detail 2B: Should the flashing in this detail be above the standing seam roof such that it will prevent water from entering beneath the roof system? Yes. The flashing should be above the standing seam roof, and the building wrap should lap the vertical flashing. MDA to issue a detail for clarification. B. Detail 4E: It is not clear to us how venting is achieved. Is attic venting intended? Shall the plywood, membrane and flashing be held back? If so, how much?
