A complete review cannot be performed until the revised plans/documents, including a written response indicating where the ‘clouded’ or otherwise highlighted changes can be found on the revised plans, have been submitted to a Permit Coordinator. nd Resubmittals must be made at the Development Services Department on the 2 Floor of City Hall. Permit Center hours are M, T, Th, & F from 8am-4:30pm. The Permit Center is closed on Wednesdays. Reviews by other divisions, such as Planning, Engineering, or Fire, may result in additional comments. General Review Notes: 1.The proposed work falls under the regulatory oversight of the Revised Code of Washington (RCW) chapter 64.55.005. As such, the following requirements must be met: A City of Edmonds ‘Special Inspection and Testing Agreement’ (see attached) must be · completed and returned prior to permit issuance. In addition to the above requirement prior to permit issuance, the following will be required before a final inspection by the City of Edmonds can be performed on, and a ‘certificate of occupancy’ can be issued by the Building Division for, the permit when issued: The ‘qualified inspector’ shall prepare and submit to the City of Edmonds Building Division · a signed letter certifying that the building enclosure has been inspected during the course of construction and that it has been constructed in substantial compliance with the building enclosure design documents. On sheet A3: 2.Foundation Plan a.Indicate on the plans the minimum required construction criteria of the continuous footings/foundations to guide proper review, construction, and inspection. b.Indicate on the plans the minimum required footing construction to support the loads from the shear walls marked ‘P1-6’ along the north wall of the two garages. c.Indicate on the plans the minimum required anchorage for the ‘HDU11’ holdowns to resist the overturning loads noted in the provided structural calculations. On sheets A4, A5, and A6: 3.Floor Plans a.Provide as part of a complete submittal, the referenced “…elevator mfgr. information for all plans, specs, dimensions, and construction notes” to guide proper review, installation and inspection. The represented configuration of the elevators requires an installation that will maintain the required fire-resistance rated construction between the dwelling units and prevent the hoist ways from acting as ‘chimneys’ during a fire. b.Verify that the installation of the proposed elevators results in ‘cars’ that meet the requirements of ICC A117.1-2009 section 408.4. c.Indicate on the plans the location of the boilers to be used as part of the proposed radiant floor heating systems. On sheets A5 and A6: 4.Floor Plans a.Indicate on the plans the requirement for exterior terminations of the water heater pan drains. b.Indicate on the plans the method(s) and locations of providing the required outdoor air per International Mechanical Code (IMC) 403.8.3. c.Clarify the indicated width of doors in the following locations: ‘Master Bath’ · ‘Master Bedroom’ closet · ‘Bedroom Two’ closet (sheet A5 only) · They do not appear to meet the minimum requirements of ICC A117.1-2009 section 1004.5.2.1. d.Clarify the placement of the water closets and of the adjacent vanities in the ‘Master Bath’. They do not appear to allow for the future installation of ‘swing-up’ grab bars required per ICC A117.1-2009 section 1004.11.1. e.Change the code reference from ‘ICC 1003.11.3.2’ to ‘ICC 1004.11.3’ for the general note regarding the selectable options and requirements for toilet and bathing facilities within ‘Type B’ units. f.Change the code reference from ‘ICC 1003.12’ to ‘ICC 1004.12’ for the general note regarding the requirements for kitchens within ‘Type B’ units. g. Change the code reference from ‘ICC 1003.11.1.2’ to ‘ICC 1004.12.1.2’ for the clearance requirements in ‘u-shaped’ kitchens within ‘Type B’ units. Page 2 of 5 h.Indicate on the plans the required clear floor space, centered on the lavatories, in the selected ‘Option B’ bathrooms per ICC A117.1-2009 referenced section 1004.11.3.1.1. i.Clarify the indicated depth of the showers in the selected ‘Option B’ bathrooms. They do not appear to comply with ICC A117.1-2009 referenced section 1004.11.3.1.3.3. j.Eliminate the representation of the doors for the showers in the selected ‘Option B’ bathrooms. They do not comply with the clear floor space requirements per ICC A117.1-2009 section 1004.11.2.1. k.Indicate on the plans the required maximum threshold heights at the exterior sliding doors in the selected ‘Option B’ ‘Great Room’ per ICC A117.1-2009 section 1004.5.2.2. On sheet A4: 5.Lower Floor Plan a.Indicate on the plans the required carbon monoxide alarm in the ‘Foyer’ per International Building Code (IBC) 908.7. b.Change the code section reference for exit passageways from ‘1021.2’ to ‘1023’. IBC 1021.2 regards required exits from stories. c.Clarify the representation of the elevators opening into the required exit passageway. It does not comply with IBC 1023.5. See also review comment ‘3.a’ above. d.Clarify the purpose of the provided detail representing the use of (2)CS16 straps placed horizontally to connect 2 separate 10-3/4x12 beams. It appears that the installation is to occur at the common wall between the separate garages to connect the two perpendicular beams, but they are noted as 7x11-7/8 PSLs. On sheet A5: 6.Main Floor Plan a.Change the wording ‘specified Type “B”’ to ‘all’ in the note regarding the installation of blocking in bathrooms to reflect that required per ICC A117.1-2009 section 1004.11.1. b.Clarify the indicated clearances around the water closets in the selected ‘Option B’ bathrooms. They do not appear to comply with ICC A117.1-2009 referenced section 1004.11.3.1.2.2. c.Indicate on the plans the means to be used to terminate the required local exhaust for bathrooms, laundry areas, etc., the dryer duct, and the vent for the fireplace, while maintaining the required fire-resistance of the floor/ceiling assembly. Terminations of the above must be coordinated with outdoor air intake requirements. Soffits, chases/shafts, etc. are sometimes used to avoid penetrations of the fire partitions and horizontal assemblies. Otherwise, penetrations must comply with IBC 714. d.Indicate on the plans the minimum required beam to be used to support the loads over ‘Bedroom Two’. The ‘typical’ 4x8 DF #2 header specified in the ‘Notes’ on the same sheet appears to be over spanned, fails in bending and in shear, and deflects beyond that allowed per IBC Table 1604.3. The provided structural calculations appear to propose a different beam at this location. Page 3 of 5 e.Clarify the callout for the 3-1/2x11-7/8 LSL to be used to support the loads over the ‘Kitchen’. It appears to be over spanned, fails in bending, and deflects beyond that allowed per IBC Table 1604.3. The provided structural calculations appear to propose a different beam at this location. f.Clarify the purpose of the provided detail representing the use of (2)CS16 straps placed vertically to connect a 10-3/4x12 beam. It appears that the installation is to occur at the exterior wall to connect the 3-1/8x9 GLB to the perpendicular beam above, but it is noted as a 7x11-7/8 PSL. 7.Handrail Notes – Change the required placement of handrails within the stairway from ‘one’ to ‘each’ per IBC 1009.15. 8.Railing Detail and Notes – Change the code version in the detail from ‘2006’ to ‘2012’. On sheet A6: 9.Upper Floor Plan - Clarify the indicated ‘swing’ of the doors to the selected ‘’Option B’ bathrooms. They do not appear to comply with ICC A117.1-2009 section 1004.11.2.1. On sheet A8: 10.Section A-A - GA File No. WP 8109 – Indicate on the plans the gypsum panel products specified for the proprietary design selected. Dependent upon the region and distributor, not all of the specified products may be available and may not be substituted for. Alternatively, a generic design, such as GA File No. WP 8105, may be selected allowing for greater choices is sourcing the required materials and adaptation to the proposed construction. Per the ‘General Explanatory Notes’ found in the Gypsum Association ‘Fire Resistance Design Manual’ insulation can be added to wall systems, greater stud widths can be substituted, and studs can be spaced closer, without affecting the design. *If the design is changed, verify that all references to the design elsewhere on the plans have been changed.* 11.Rated Wall Locations a.Type ‘A’ – See review comment above. b.Type ‘B’ – Clarify the callout for the design of the required one-hour fire-resistance rated interior wall construction. GA File No. WP 8109 is a ‘proprietary’ exterior wall design, limited to the use of the materials specifically listed in the design. The note: “This assembly provides for an STC rating of 34 to 39.” does not appear to correspond to the information found in the Gypsum Association ‘Fire Resistance Design Manual’ for that design. Common interior walls, partitions, and floor/ceiling assemblies between adjacent dwelling units or between dwelling units and adjacent public area such as the foyers and stairs identified on the plans must have a STC of no less than 50 per IBC 1207.2 and IBC 1207.3, in addition to providing the required fire resistance. Most of the wall designs meeting the STC utilize a ‘double-stud’ or ‘staggered-stud’ design and, per IBC 1207.2, require measures be taken to maintain the required sound ratings for openings to accommodate mechanical, plumbing, and electrical systems (see also Gypsum Association ‘Fire Resistance Design Manual’ – Section III – Sound Control). The dimensions of these walls may significantly affect the required and desired widths of the various spaces shown on the plans. c.Type ‘C’ – Indicate on the plans the corresponding ‘file number’ for the indicated one hour floor/ceiling assembly. Page 4 of 5 On sheet G1: 12.Design Data – Frost Line – Change the required minimum depth of the footing below finish grade from ‘12 inches’ to ‘18 inches’ per the information in Edmonds Community Development Code (ECDC) 19.05.020.
