As a continuation of the previous account Group Mackenzie's experience with police facility design, space standards for policing study, Group Mackenzie worked closely with the facilities, and dialogue with the City of Tigard Police Department to develop a facility program for Police Department. This investigation began with spatial requirements—both present and future—in a walkthrough and examination of the existing an effort to aid the City in identifying next steps and facility conditions, workflow, and operational prioritizing capital improvement projects moving efficiencies of the space allocations, adjacencies, forward. and circulation flow. Following examination of the existing conditions, the Design Team conducted GROUP MACKENZIE interviews with Police Department staff from all Established in 1960 and based in Portland, divisions to facilitate compilation of the included Oregon, Group Mackenzie provides a range of space needs findings. professional design services, including structural engineering, architecture, landscape architecture, PROJECT BACKGROUND civil engineering, land use planning, transportation planning, and interior design.

Altogether, the Police EXISTING FACILITY Department currently operates out of approximately EXAMINATION 15,849 square feet. After reviewing the previous report prepared by LRS Examination of the existing facility conditions Architects in 2009, the first step in development of revealed a number of concerns related to space the Department's space needs involved touring the allocations, adjacencies and general performance existing police facility located at the Tigard Civic of the building. The primary deficiency, however, Center at 13125 SW Hall Blvd. To accomplish is the lack of available space required for current this task, Group Mackenzie worked closely with operations. Primary concerns noted through the the City of Tigard Police Department to identify evaluation of the existing facility include: and document spatial deficiencies, security • Existing building does not meet the seismic concerns, police and public access and interaction, requirements as outlined in the ASCE 31 Tier 1 accessibility, and interdepartmental relationships.

This validation strategy is police facility requirements and those particular to utilized and coupled with information provided by the City of Tigard Police Department. To allow for a the City and Police Department regarding crime comprehensive analysis, the Design Team evaluated trends, City growth, staff projections, population both single-story and two-story adjacency concepts. growth and statistics that play a role in future projections and development.

Relationships with other City functions are Development of the space needs programming also important to consider. Currently, the determined a site space requirement for a two-story Department interacts most frequently with the building option of approximately 128,017 square City Administration, Municipal Courts, Human feet or 2.94 acres of developable land. Based on Resources, Risk Management, Finance, Information this need, it was confirmed that the 3.76-acre SW Technology, and Public Works (for fleet and facility Burnham site is large enough to accommodate management). Further, the Police currently share the projected growth of a 2034 facility build-out. the following functions and spaces with other City Following confirmation of the program space departments: town hall, various conference rooms, requirements, Group Mackenzie moved forward lunchroom, plotter, mailroom, restrooms, lobby, with Task F to conceptually test fit the site for full parking, information technology. build-out of the projected facility growth and required site improvements for public and secure TASK E & F : SITE SELECTION parking.

The scale of the GROUP MACKENZIE Executive Summary continued improvements also necessitates consideration of space needs program for both the building as well and adherence to land-use planning requirements as secure and public parking. A key advantage for the downtown urban core, requiring design of both options, particularly Option B, is that the conformance along the property frontage and available site allows for development of all the to parking requirements. Based on the required parking on grade, which greatly reduces potential space needs, the site itself is capable of supporting development costs of the project.

Secure parking 2.8 GROUP MACKENZIE TIGARD POLICE SPACE NEEDS ASSESSMENT PROGRAM & SPACE STANDARDS 3 GROUP MACKENZIE TIGARD POLICE SPACE NEEDS ASSESSMENT THIS PAGE IS INTENTIONALLY LEFT BLANK PROGRAM SUMMARY Group Mackenzie has developed Space Standards (3.11 and 3.12) that inform the size and layout of typical program elements for policing facilities. These space standards have been used to aid in the development of the building program. Beyond the building program requirements, there are important site elements and considerations that must be taken into account for a police facility. These additional program elements include public parking; secure parking for staff, police vehicles and equipment; emergency power; building threat protection; and access to and from the site. The most challenging consideration, for any site, stems from public and secure parking requirements. These are governed by jurisdictional requirements as well as department growth projections and space requirements for vehicles and equipment. Group Mackenzie has found that police facilities constructed for growth average approximately 500 square feet per staff member. For Tigard Police, projected growth equates to 493 square feet per staff member for 20 years of future growth. This average is based on staff that will occupy the building at the completion of construction in 2014.

The building appeared to be in fair condition for a structure of this era. The original structural drawings, prepared by KPFF Consulting Engineers, dated April 8, 1985, were available for review. Construction documents indicate that the original police wing was engineered with considerations for a second floor.A later addition was constructed in 1994 on the north end of the police facility and was comprised of similar light framed construction. The structural drawings of the addition, prepared by Hanson, Dunghugh, Nicholson Architects PC, dated 9/6/1996,were also available for review. The seismic provisions in the current Oregon Structural Specialty Code have changed significantly since the facility was originally designed, and the purpose of this report is to identify potential seismic deficiencies in the structural system and potential repair schemes. ASCE 31 ANALYSIS The seismic evaluation was conducted using ASCE 31 Seismic Evaluation of Existing Structures. This document is not a code, but a nationally-recognized standard used by engineers to evaluate existing buildings.ASCE 31 incorporates a multi-tier methodology for evaluating existing structures. Tier 1,which was selected for this analysis,is a preliminary screening phase which utilizes a checklist approach to identify potential seismic hazards.It should be noted that at this stage,any identified risks are preliminary and may or may not be justifiable using a higher tier analysis. Tier 2 and Tier 3 are the evaluation and detailed evaluation phases respectively,which were not conducted at this time.The analyses in these tiers further evaluate the flagged deficiencies identified during the Tier 1 screening phase. After the seismic evaluation is completed, a different document, ASCE 41 Seismic Rehabilitation of Existing Buildings, may be used to complete a seismic retrofit design to address issues identified in the evaluation stage. ASCE 31 allows two performance levels to be targeted which can be correlated to the amount of post-earthquake damage expected. The Life Safety (LS) performance level is meant to ensure the safety of building occupants; however, the building will likely experience significant damage that may or may not be repaired or occupied after the 7.2 GROUP MACKENZIE Appendix continued earthquake.The Immediate Occupancy(IO)level is meant to limit building damage such that the building may be occupied and functional directly after the seismic event. As a police station is an essential facility for post-disaster operation, the analysis conducted for this report utilized the IO performance level. The Tier 1 analysis consists of a visual survey which was conducted on May 16,2013(see Appendix C for photos from this site visit). For each of the Tier 1 checklist items, an evaluation of Compliant(C),Non-compliant(NC),or Not Applicable(N/A)is marked.NC does not necessarily mean that the issue cannot be justified with a higher tier evaluation phase,just that it does not pass the Tier 1 screening criteria. As a part of the Tier 1 screening phase various analyses or"Quick Checks,"were performed where specifically required.Calculation sheets L1 through L6 associated with the analyses are included in Appendix A of this report. It may be noted that to determine the seismic forces and associated masonry shear wall stresses, the interior partition walls were not utilized. See calculation sheet L6 for a reference plan and brief description of seismic force distribution. SCOPE AND LIMITATIONS This Tier 1 analysis is based on site observations of only readily visible items. It should be noted that other deficiencies might exist that have not been identified by this screening phase and quick checks.In addition,no material or other testing was performed at this time for review. EVALUATION RESULTS Evaluation Criteria The level of seismicity was determined at the site and compared to the ASCE 31 level definitions(see Table 2-1).For the Police Depar Intent,SDs=0.706 and SD1=0.390;therefore, the site is considered to be in an area of high seismicity. Table 2-1.

The Basic and Supplemental Structural, Geologic and Foundation,as well as the Basic,Intermediate and Supplemental Non-structural checklists are required.

ASCE 31 has different checklists depending on the building construction type.This building type is classified as a combination of W 1/W2,wood frame/wood shear panel construction and RM1, reinforced masonry / flexible diaphragm construction. Due the age of this building, it is assigned the "benchmark" status for building type W 1 / W2 but, not for building type RM1. The "benchmark" status is assigned by ASCE 31 to building types designed under specific building code provisions or later, for various building types (see Table 3-1). "Benchmark Buildings," as defined by ASCE, are those designed and built recently enough to assume that their structural systems have acceptable seismic performance and an evaluation is not required. Summary of ASCE 31 Tier 1 Evaluation The Tier 1 screening phase identified numerous structural and non-structural items as non- compliant.Non-compliant issues require further evaluation in order to determine their full impact on the seismic performance of the building, but these issues are a relatively good indicator of potential performance problems. A summary of non-compliant issues is presented below organized by each checklist.Copies of the Tier 1 checklists and calculations are included in this report in Appendix A. Basic Structural Checklist Type RM1 • Wall Anchorage—The masonry walls are inadequately tied to the roof diaphragm for in-plane and out-of-plane forces.No steel plates,straps,or anchorage is indicated on construction documents. • Wood Ledgers—Note that the masonry walls have top plates at bearing conditions and are compliant for gravity loads;however,the lack of steel wall anchorage requires out- of-plane wall forces to be transferred through cross grain bending in the wood top plates. • Transfer to Shear Walls—The wood roof diaphragm connection to shear walls is not shown on the drawings indicating that a steel connection capable of developing drag forces to the shear walls is not present. • Foundation Dowels—Preliminary analysis indicates that the existing dowel to slab capacity is not capable of resisting the design shear in the CMU shear walls.Further detailed analysis will likely confirm that the foundation anchorage is capable of resisting existing loads. TIGARD POLICE SPACE NEEDS ASSESSMENT 7.5 Appendix continued Supplemental Structural Checklist Type RM1 • Cross Ties—There are not continuous cross ties in the diaphragm in either direction. • Plan Irregularities — There does not appear to be connections at re-entrant corners capable of developing the strength of the diaphragm. • Unblocked Diaphragms —Unblocked wood structural roof diaphragms exceed the maximum limits for roof diaphragms. • Stiffness of Wall Anchors—There does not appear to be dedicated wall anchors with capacity to ensure relative movement will be limited. Geologic Site Hazards and Foundations Checklist It should be noted that the potential for soil liquefaction, slope failure, and surface fault rupture at this site is unknown and is beyond the scope of our investigation. The site is located adjacent to Fanno Creek and subsequently a slope away from the site. Further analysis, performed by a Geotechnical Engineer, is required to determine if this site is compliant.Based on our experience with similar sites liquefaction and surface fault rupture would not appear to pose significant threats to this building. Basic Non-Structural Checklist • Light Fixtures—There do not appear to be dedicated bracing of light fixtures that is separate from ceiling panels indicating that there is no special detailing to prevent falling during an earthquake. • Ties—Masonry veneer ties are not specified in the construction documents.However, the extent of masonry veneer falls below 4 feet in height and is not located above any openings. • Weakened Planes—Masonry veneer anchorage is not specified in the construction documents.However,the extent of masonry veneer falls below 4 feet in height and is not located above any openings. • Tall Narrow Contents—No lateral bracing is provided. • Piping Flexible Couplings—Not provided. Intermediate Non-Structural Checklist • Lay-In Tiles—Tiles located at exits and corridors are not secured to suspension system with clips. • Independent Support — A number of fixtures observed did not have independent support. Supplemental Non-Structural Checklist • Partitions Drift—There did not appear to be special partition detailing to accommodate substantial building drift however, partitions did appear to be braced to current industry standards. • Ceiling System Edges—Not detailed to hold 1/2"gap between ceiling and walls. • Glazing—No indication that window glazing is laminated, annealed, or laminated heat-strengthened safety glass. • File Cabinets,Cabinet Doors,and Drawers—Latches and bracing are not provided for all furniture pieces. • Mechanically Operated Doors—Not detailed to accommodate drift ratio requirements. 7.6 GROUP MACKENZIE Appendix continued REPAIR RECOMMENDATIONS The Tier 1 deficiencies listed above will require further evaluation(ASCE 31 Tier 2 or 3 analyses) or the design of a seismic retrofit using the ASCE 41 standard. The following narrative describes the approximate scope of one possible retrofit scheme to address the identified deficiencies. A cost estimate for the described repairs is also included (see Appendix B). 1. Masonry anchors and cross tie strapping at the roof diaphragm should be added to connect each roof joist to the masonry walls that they are supported by(at locations where masonry walls run in an east and west direction). 2. At masonry walls running in a north and south direction,new sub framing(2x6's at 4'- 0"on center extending approximately 8'-0"from the wall)and masonry anchors should be installed below the roof decking. Anchor rods with hold downs should be added from below the roof,or strapping should be added to the roof from above at the added blocking.Utilities in this area may need to be addressed as part of this installation. 3. All tall and heavy equipment/storage must be adequately anchored and should remain latched if not in use. 4. All fire suppression lines and gas lines should be verified to be able to accommodate expected building drift or alternatively flexible couplings could be added. 5. The suspended ceiling tiles near the exits should be clipped to the supporting grid system and the lights in these areas should have independent support and bracing. 6. The suspended ceiling should be modified to include a 1/2" separation from all full- height partition walls. 7. All light fixtures should be independently supported by at least two wires at diagonal opposite corners of the fixtures. 8. All mechanical,electrical and plumbing equipment and utility lines shall be braced. 9. The glazing in the window systems near the building exits should be replaced with laminated safety glass. 10. Flexible couplings shall be installed at the utility lines as they enter the building. 11. The mechanically operated Sally Port doors would need to be altered to allow building movement without damaging or jamming the doors. A complete analysis of the building and seismic force resisting system must be conducted to fully understand all the issues that would require repairs,which is beyond the scope of this investigation.Depending on the results of these investigations,there may be changes to the list of repairs above. Once a complete analysis and design of a seismic upgrade has been completed,the Tigard Police Department can be expected to remain occupied and functional after a seismic event of the size expected in the region.
