CASHIER RECEIPT NUMBER: ��t [ 40 5 FonnsWodff 02/25/21 Guidelines for Approval of Alternate Materials Design and Methods of Construction Basis For Approval For the Chief Building Official and Fire Code Official or their designated agent to approve a request for modification or a request for alternate material or method of construction, he/she must determine that special, individual reasons exist that make compliance with the strict letter of the Code impractical and that equivalency is provided. The resulting condition must be in conformance with the spirit and purpose of the Code provisions involved and that such modification does not lessen fire protection, structural integrity or occupant safety. The applicant must provide sufficient information with this application to allow the above evaluation to be made. Requirements for Submittals The applicant design professional shall prepare a Written Report that describes the alternate proposal along with the applicable data listed below: • State specific code provisions for which alternative is requested and why request is being submitted. • Describe by code section those provisions for which alternative is desired. • Compare the proposed alternative versus the code requirements in terms of structural strength, suitability, effectiveness, fire resistance, safety and health impacts affecting the building or user of the building. • Demonstrate that the proposed alternative is compatible with balance of code requirements. • When applicable, specify how authoritative consensus document(s) are used to substantiate proposal. (Reference draft ICC Building Performance Code Commentary Section 1.4.2.3 for background information). • Provide assumptions, references, and documentation of evaluation methods utilized. This includes intended use, input data, anticipated outputs, and limitations of computer models and other analytical tools or methods. • Specify when and where special inspection and testing are required and the standards of acceptance for demonstrating compliance. Show how the proposed alternate, if accepted, will be identified on the job site. • Where land use restrictions and building setbacks are required, deed restrictions may be an appropriate method to ensure continued compliance. • State how and where alternate proposal is incorporated within construction plans and prepare plan amendments as necessary. The design professional has the responsibility to coordinate all construction documents and ensure compatibility between documents. • The report and design documents shall be dated, signed and stamped by the design professional according to the plan submittal procedure. • For alternate methods of design requests, the applicant shall set performance criteria for his design. Performance criteria shall be reviewed, amended and approved by the Building or Fire Code Official prior to start of design. _Alternative Design ReviewNerification The Chief Building Official or Fire Code Official has the responsibility to review design submittals for compliance to the adopted codes and procedures. If the Building or Fire Code Official does not have the expertise on staff to make a thorough and competent review, the Building or Fire Code Official shall select a consultant that possesses the necessary qualifications to perform a third -party or peer review. Cost of peer review shall be paid by applicant to the Building Division prior to commencing the review. • Verify that all applicable information and justifications listed above as requirements for submittals is received and verify that evaluation and design methods used by designer are appropriate to the alternative proposed. • Verify products are being used in accordance with their listing conditions as required by recognized listing agencies. If not available, require documentation and/or testing to demonstrate compliance with intent of code and intended use. • Evaluate performance of material and possible flaws that could affect performance of material in its installed state. • The reviewer shall document that the submittal has been reviewed and accepted as meeting the alternative materials, design and methods of construction provisions of the code. If the Building or Fire Code Official is not satisfied that the applicant has met the conditions, the request should be denied in writing with the applicable reason(s). Inspection/Field Verification The alternate proposal as approved in the construction documents must be verified by inspection, and, where necessary, testing as follows: • To verify that alternate materials, systems and fabricated products comply with accepted design criteria and the manufacturer's and engineer's installation procedures, inspectors should check product labeling, certification, quality assurance processes, and testing, as applicable. • When appropriate, an approved third party quality assurance inspection and testing service may be required for continuous and complex inspection and testing activities. This is intended to verify that construction complies with the code and the approved plans. Appeal trom the determination or action of the Chief Building Official or Fire Code Official or their designated agent may be made to the Building and Fire Board of Appeals. To appeal, the applicant must provide special individual reasons that make compliance with the strict letter of the Code impractical. Appeals or ratifications pertaining to State Disabled Access Standards require complete evidence to substantiate that the proposed design is equivalent to that prescribed by that standards or that due to legal or physical constraints, compliance with the standards or providing equivalency would create an unreasonable hardship. Appeals must be submitted on the Appeal Form available at Permit Counter accompanied by the proper fee. You will be notified in writing of the appeal hearing's time and date.

This tool helps in establishing light -on -dark or dark -on -light contrast differences, allowing the selection of a detectable ADA Tile color and a surrounding concrete color while displaying a percentage of contrast based on the LRV scale. This percentage of contrast can assist the governing body in developing the level of contrast that best meets the needs of the community. What is LRV? Light Reflectance Value (LRV) is a universal value for 'contrast. It measures the proportion of useful light reflected by a colored object. It represents a relative light and darkness value rather than an actual color. meaning dissimilar colors could have the same LRV. LRV is measured on a scale of 0 to 100, 0 being an all absorbing black and 100 being an all reflecting white ADATile Color Concrete Color Natural Colors Federal Colors LM ADA Tile Color F?tl�r3l ElaCc �jI Concrete Color ca°o�Lz -JI Armor -Tile Tactile Systems MATERIAL WARRANTY* Contract No./Date: 21ICMA014.C1 / March 22, 2021 *issued on a per project basis Project Description: CRC- BYC MARINA ACCESS GATE UPGRADES Contractor/Sub: TBD Owner: Fremont CRC Marinas ro uct Installed: x4 On Bac Engineered Plastics Inc. warrants to the Owner that Armor -Tile Detectable Warning Tiles manufactured by Engineered Plastics Inc. are free from defects in workmanship and material including deformation, breakage and delamination for a period of Five (05) years from the date of acceptance of the project.

Adhesive: Tactile Bond and Seal (TBS) as supplied by Engineered Plastics Inc. C. Sealant: Tactile Bond and Seal (TBS) as supplied by Engineered Plastics Inc.. PART 3 EXECUTION 3.01 INSTALLATION A. During all surface preparation and installation procedures, ensure adequate safety guidelines are in place and that they are in accordance with the applicable industry and government standards. B. The application of all tiles, adhesives, mechanical fasteners, and caulking shall be in strict accordance with the guidelines set by their respective manufacturers. Not recommended direct asphalt applications. Surface Applied Detectable/Tactile Warning Surface Tile January2020 Section 3217 26 Page 5 C. Coordinate with the Contractor or Engineer to ensure that the surfaces being prepared and fabricated to receive the tiles are constructed correctly and adequately for tile installation. Review manufacturer and contract drawings with the Contractor prior to the construction and refer any and all discrepancies to the Engineer. D. Set the tile true and square to the curb ramp area as detailed in the design drawings, so that its location can be marked on the concrete surface. A thin permanent marker works well. Remove tile when done marking its location. E. The surface to receive the Surface Applied Warning tile is to be mechanically cleaned with a diamond cup grinder or shot blaster to remove any dirt or foreign material. This cleaning and roughening of the concrete surface should include at least 4 inches around the perimeter of the area to receive the tile, and also along the cross pattern established by the corresponding areas on the backside of the tile. Those same areas should then be cleaned with a clean rag soaked in Acetone ensuring all dust and debris are removed. F. Immediately prior to installing the Surface Applied Warning tile, the concrete surfaces must be inspected to ensure that they are clean, dry, free of voids, curing compounds, projections, loose material, dust, oil, grease, sealers and determined to be structurally sound and cured for a minimum of 30 days. G. Using Acetone, wipe the backside of the tile around the perimeter and along the internal cross pattern, to remove any dirt or dust particles from the area to receive the adhesive. H. Apply TBS to the backside of the tile, following the perimeter and internal cross pattern established by the tile manufacturer. Sufficient adhesive must be placed on the prescribed areas to have full coverage across the 2" width of the adhesive locator and shall be applied to within %" continuously around the perimeter edge of the tile. The entire tube of adhesive shall be applied to the back of each tile, sizes 24 x 36 in. and greater. I. Set the tile true and square to the curb ramp area as detailed in the design drawings. J. Working from the center of the tile outwards, proceed to drill and install all fasteners in the tile's molded recesses. K. Standing with both feet applying pressure around the molded recess provided in the tile, drill a hole true and straight to a depth of 3'/:" using a''/<" masonry drill bit. Drill through the tile without hammer option (on the drill) until the tile has been successfully penetrated, then with hammer option (on the drill) to drill into the concrete. Maintaining foot pressure on both sides of the hole while drilling prevents concrete dust from accumulating between the tile and concrete which can affect the tile being installed flush and may compromise installation integrity. L. Immediately after drilling each hole, before moving on to the next, and while still applying foot pressure, mechanically fasten tiles to the concrete substrate using a leather bound or hard plastic mallet to set the fasteners. Ensure the fastener has been placed to full depth in the dome, straight, and flush to the top of dome. Drive the pin of the fastener with the mallet, taking care to avoid any inadvertent blows to the truncated dome or tile surface. M. Following the installation of the fasteners, the concrete dust should be vacuumed, brushed or blown away from the tile's surface and adjacent concrete. Using Acetone on a rag, wipe the concrete around the tile's perimeter to ensure a clean, dry surface to receive perimeter sealant. Surface Applied Detectablejractile Warning Surface Tile January 2020 Section 3217 26 Page 6 N. TBS perimeter caulking sealant should be applied following the sealant manufacturer's recommendations. Tape all perimeter edges of the tile back 1/16" from the tile's perimeter edge and tape the adjacent concrete back Y2" from the tile's perimeter edge to maintain a straight and even caulking line. Apply sealant around tile perimeter using care to work sealant into any void between the tile and concrete interface. Tool the perimeter caulking with a rounded plastic applicator or spatula to create a cove profile between the tile and adjacent concrete. Remove tape immediately after tooling perimeter caulking sealant. O. Do not allow foot traffic on installed tiles until the perimeter caulking sealant has cured sufficiently to avoid tracking. Curing time is weather dependent (average cure time at 75° F is 30 minutes). Adhesive or caulking on the surface of the Armor -Tile can be removed with Acetone. P. If installing adjacent tiles, note the orientation of each tile. Careful attention will reveal that one of the long edges of the tile is different than the other in regard to the tiny dotted texture. You may also note a larger perimeter margin before the tiny dotted texture pattern begins. Consistent orientation of each Armor -Tile is required in order that the truncated domes on adjacent tiles line up with each other. Q. In order to maintain proper spacing between truncated domes on adjacent tiles refer to the drawings for correct installation. The use of a continuous rim Diamond blade and a straightedge to guide the cut if required. All cuts should be made prior to installation of the tiles. If installing adjacent tiles, care should be taken to leave a 1/8" gap between each tile to allow for expansion and contraction. R. If tiles are custom cut to size, if pre -molded recesses (to receive fasteners) are removed by the cut, or to maintain a tight installation to the substrate then any truncated dome can be center - drilled with a''/<" masonry drill bit to create a through hole, and the through hole must be countersunk with a suitable carbide countersink bit to receive mechanical fasteners. Care should be taken to not countersink too widely or deeply. Fasteners should be flush with the top of the truncated dome when countersunk properly. 3.02 CLEANING, PROTECTING AND MAINTENANCE A. Protect tiles against damage during construction period to comply with Warning tile manufacturer's specification. B. Protect tiles against damage from rolling loads following installation by covering with plywood or hardwood. C. Clean tiles not more than four days prior to date scheduled for inspection intended to establish date of substantial completion in each area of project. Clean tile by method specified by tile manufacturer. D. Comply with manufacturer's maintenance manual for cleaning and maintaining tile surface and it is recommended to perform annual inspections for safety and integrity.
