Box 185 Allyn, WA 98524 CodeProsWA.com NUMBER OF STORIES: 2 / 1 CODE EDITIONS: 2018 International Building Code (WAC 51-50); and 2018 International Mechanical Code (WAC 51-52); 2018 Uniform Plumbing Code (WAC 51-56); 2018 Washington State Energy Code (WAC 51-11C); Dear Mr. Wellner, The building design documents submitted for the three building permit applications referenced above have been reviewed for conformance with the locally adopted codes along with the Washington State amendments. This review letter contains only those comments related to the Building Department’s review and does not reflect any additional needs of any other division or County department. Please also recognize, that this letter may be considered preliminary, as without complete architectural plans, additional comments may become necessary upon review of resubmitted complete construction plans. Absent an architect of record, please also consider assignment of an architect of record, engineer of record, or some other “Design Professional in Responsible Charge” to oversee the preparation and coordination of plans for the project, and to satisfy the requirements of IBC Section 107.3.4. Please review the project data above, and the plan review comments below. It is important that you then follow the instructions for re-submittal following the plan review comments. PLAN REVIEW COMMENTS: Comments for Buildings J under application BLD2021-00301: 1. There does not appear to be a full architectural plan. While the structure is substantially represented in the structural plans, Sheets L1.1 and L1.2 appear to be the only “architectural” plans included. Is there a full set of architectural plans? 2. L1.1 & L1.2. The Code Summary identifies the project to utilize the 2015 International Building Code (IBC) and 2015 Washington State Energy Code (WSEC). The project, submitted after February 2021, shall satisfy the requirements of the 2018 editions of the codes adopted by the State of Washington and Jefferson County. Please clarify and/or correct. 3. L1.1 & L1.2. The Code Summary identifies the building as a Construction Type III-B. Type III- B buildings are comprised of minimum 2-hour exterior bearing walls in accordance with IBC Sections 601, 602, and 704.10. The plan goes on to note the north and south bearing walls are 2-hour rated (from the inside only); however, the plans do not include any rated assembly or construction details for rated exterior wall assemblies. Please clarify and/or correct. (Note: Otherwise, if the exterior bearing walls are not 2-hour fire-resistive rated, then the buildings would be considered Construction Type V-B, which would also require revisions to the allowable area calculations.) 4. Energy Code compliance forms utilized are for the 2015 edition of the WSEC. This project shall satisfy the 2018 Washington State Energy Code. Revised, updated compliance forms should be provided. 5. S1.1J & S1.2J. IBC 706.6 requires vertical continuity of fire walls to extend a minimum of 30 inches above the roof unless certain exceptions are satisfied. The plans do not describe a continuation above the roof, nor are any of the 706.6 exceptions noted or components described if the proposal is to utilize one of the conditional exceptions. Please provide a description and/or complete details of how the requirements of IBC 706.6 will be satisfied. CodePros, LLC Page 3 of 5 P.O. Box 185 Allyn, WA 98524 CodeProsWA.com 6. S1.1J & S1.2J. The building is provided with a 3-hour fire wall in order to separate the building into multiple fire areas, each less than 12,000 square feet in order to avoid an automatic fire sprinkler system requirement (IBC 903.2.9). The fire wall is shown with door openings. The Plan Key Notes identifies the doors to be “3-hour rated doors” but continue with “By Others.” Without full architectural plans, if the structural plans are to supplement as the architectural design, Doors such as the 3-hour fire doors should be fully described, and included as part of the plan set, without a confusing reference of “by others.” Please fully identify the rated door assemblies proposed indicating satisfaction of IBC Section 716.5 and Table 716.5 and clarify that they are included as part of this project. 7. S2.0J. The Building J Section at 1/S2.0J appears to have the corridor locations reversed between upper level and lower level. Please correct the discrepancy to avoid confusion. 8. The geo-technical engineer recommends installation of foundation drains at the perimeter of each building and along the heel of the retaining walls. The foundation wall details on Sheet S3.0 refer to “Ftg drain by others” and “Footing drain by civil”, though the civil drawings do not appear to include the footing drain system. Please clarify that the footing drains will be included and specify pipe type and material, installation requirements, grades and discharge locations. Comments for Buildings A under application BLD2021-00303: 9. There does not appear to be a full architectural plan. While the structure is substantially represented in the structural plans, Sheets L1.1 and L1.2 appear to be the only “architectural” plans included. Is there a full set of architectural plans? 10. L1.1 & L1.2. The Code Summary identifies the project to utilize the 2015 International Building Code (IBC) and 2015 Washington State Energy Code (WSEC). The project, submitted after February 2021, shall satisfy the requirements of the 2018 editions of the codes adopted by the State of Washington and Jefferson County. Please clarify and/or correct. 11. L1.1 & L1.2. The Code Summary identifies the building as a Construction Type III-B. Type III- B buildings are comprised of minimum 2-hour exterior bearing walls in accordance with IBC Sections 601, 602, and 704.10. The plan goes on to note the north and south bearing walls are 2-hour rated (from the inside only); however, the plans do not include any rated assembly or construction details for rated exterior wall assemblies.

S1.1A & S1.2A. IBC 706.6 requires vertical continuity of fire walls to extend a minimum of 30 inches above the roof unless certain exceptions are satisfied. The plans do not describe a continuation above the roof, nor are any of the 706.6 exceptions noted or components described if the proposal is to utilize one of the conditional exceptions. Please provide a description and/or complete details of how the requirements of IBC 706.6 will be satisfied. 13. S1.1A & S1.2A. The building is provided with a 3-hour fire wall in order to separate the building into multiple fire areas, each less than 12,000 square feet in order to avoid an automatic fire sprinkler system requirement (IBC 903.2.9).

Please clarify that the footing drains will be included and specify pipe type and material, installation requirements, grades and discharge locations. Comments for Buildings E under application BLD2021-00302 are as follows: 16. There is no architectural plan or interior layout plan provided. While the structure is substantially represented in the structural plans, no plans are provided to describe basic construction type, building height and area, interior configurations, proposed uses, accessibility, egress systems, etc. Please provide a complete architectural plan for the proposed project that include satisfaction of IBC Sections 107.1 and 107.2. 17. The Energy Code compliance forms submitted are for the 2015 edition of the code. This project shall satisfy the 2018 Washington State Energy Code. This building is also identified in the compliance forms as a “semi-heated” building (as opposed to a “low-energy” building suggested for Buildings J and A of the same complex). Please be sure the architectural plans include all necessary building thermal envelope and mechanical system components required for a semi- heated building, as described in WSEC Section C402.1.1.2. 18. The geo-technical engineer recommends installation of foundation drains at the perimeter of each building and along the heel of the retaining walls. The construction plans do not depict any form of footing/foundation drains. Please clarify. Overall: 19. The project requires that restrooms be provided in a number and location that satisfy the requirements of IBC Chapters 29 and 11, as well as the accessibility requirements of ICC/ANSI A117.1. References are made to existing restrooms in the primary office building, however, no description of the facilities has been provided, nor have distances been described, number of fixtures, accessible routes, etc. If restroom facilities are not to be included in the newly proposed buildings, please provide an explanation and description of existing accessible facilities that are suitable to serve the increased occupant loads proposed. Unfortunately, the construction plans cannot be recommended for approval for building permits until all outstanding issues are resolved. To re-submit plans: Please make the required corrections and/or clarifications and submit revised electronic copies of the plans (.PDF or .DWF) clearly identifying all revisions. Submitted electronically, once approved, the electronic sets will contain the approval indications and will be returned to the City electronically for the City record, and copies will be provided to the applicant/architect in order to print off official “Approved Site Copy” of the plans to be maintained on- site during construction.
