<h1>ATS: Three Methods of Specification</h1>
  <p>We recognize that specifying the Simpson Strong-Tie Strong-Rod&reg; Anchor Tiedown System (ATS) for shearwall overturning restraint is unlike choosing any other product we offer. You must first address <a href="/products/lateral-systems/strong-rod-systems/ats/designer-tools/design-considerations">several design questions and considerations</a> to ensure that the system will be configured to meet the design's intent. For example, when determining whether to use Strong-Rod Systems or conventional holdowns and strapping, a designer must determine the project's incremental and cumulative loads or specification of elongation and system deflection limits. The designer will need to determine the compression posts, sheathing thickness and grade, nailing schedule, horizontal drift, and meet all other requirements in accordance with the applicable building code.</p>
  <p>We currently offer the following three methods of specifying:</p>
  <div class="row">
    <div class="col-md-6">
      <h3 class="h4">Your Partner During the Project Design Phase</h3>
      <p>During the designer's preparation of the construction documents, Simpson Strong-Tie can be contacted to create the most cost-effective customized runs. These runs include detailed design calculations for each shearwall overturning restraint requirement and design drawings with all the necessary details to install the ATS system. The Design engineer will work closely with Simpson Strong-Tie Engineering Services to provide all the necessary information required to design the system.</p>
      <ul>
        <li>The design code for the project</li>
        <li>Sill/sole plate species and size</li>
        <li>System elongation limits at each level</li>
        <li>Type of floor system and depth</li>
        <li>Cumulative tension and compression loads at each level<br>
        </li>
        <li>Wall heights<br>
        </li>
        <li> Anchor diameter</li>
        <li>Type of run start and termination</li>
      </ul>
      <p>Simpson Strong-Tie has provided an easy-to-use spreadsheet to assist the designer in providing all the necessary information. The spreadsheet can be <a href="/products/lateral-systems/strong-rod-systems/ats/designer-tools/customized-runs">downloaded here</a>. The completed spreadsheet can be emailed to <a href="mailto:engineeringservices@strongtie.com">engineeringservices@strongtie.com</a>. The completed design calculations, drawings, notes and specifications prepared by Simpson Strong-Tie Engineering Services can then be incorporated into the design documents that the designer will be submitting to the building official. </p>
    </div>
    
    <div class="col-md-6">
      <h3 class="h4">Handling Deferred Submittals</h3>
      <p>The designer may also choose to provide general specifications and loads in the construction documents and require the contractor to submit deferred design calculations and shop drawings. The designer can <a href="/products/lateral-systems/strong-rod-systems/ats/details-specifications/general-notes">download generic specifications and notes</a> to place in the construction documents at strongtie.com/srs. Generic details can also be obtained to insert into the designer’s construction documents. </p>
      <p>Some of the items required to be included in the designer’s construction document are:</p>
      <ul>
        <li>General Notes for rod system design </li>
        <li>System elongation limits at each level </li>
        <li>Cumulative tension and compression loads at each level</li>
        <li>Anchor diameter</li>
        <li>Details of system run start and termination </li>
      </ul>
      <h3 class="h4">Specify Run ID Callouts</h3>
      <p>An option for designers who prefer to specify their own ATS system is to specify run IDs predesigned by Simpson Strong-Tie. These run IDs can be specified in the designer’s construction documents with associated details. The designer will be required to determine the overturning tension force required at each level and choose the run ID from the tables. The steps to follow as well as the tables are <a href="/products/lateral-systems/strong-rod-systems/ats/designer-tools/table-id-runs">available on our website</a> based on the number of floors and the necessary capacity. </p>
