This week\u2019s quiz is from <a href=\"https:\/\/www.constructionspecifier.com\/roof-drainage-tapered-insulation-systems\/\"><em>Tapered insulation systems: The art of roof drainage<\/em><\/a> by Darrell L. Smith, the facilities principal engineer with <a href=\"https:\/\/www.ecslimited.com\/\">Engineering Consulting Services (ECS) Midwest LLC<\/a>. Understanding the 2021\u00a0<em>International Building Code<\/em> (<em>IBC<\/em>) and <em>International Plumbing Code<\/em> (<em>IPC<\/em>) is essential for effective roof drainage design. This quiz explores key concepts related to low-slope roofs, drainage systems, and various methods to ensure proper water flow and stormwater management. Test your knowledge on minimum slope requirements, roof drainage systems, materials for tapered insulation, and proper design for new and re-roofing projects.<\/p>\n<p>Take this week\u2019s quiz and challenge yourself!<\/p>\n<link rel='stylesheet' id='formidable-css' href='https:\/\/www.constructionspecifier.com\/wp-content\/plugins\/formidable\/css\/formidableforms.css?ver=20261026153039' media='all' \/>\n<div class=\"frm_forms  with_frm_style frm_style_formidable-style\" id=\"frm_form_46_container\" data-token=\"a19240af6bc9d44eaff686d0878fc389\">\n<form enctype=\"multipart\/form-data\" method=\"post\" class=\"frm-show-form  frm_js_validate  frm_pro_form \" id=\"form_quiz5222\" data-frm-error-config=\"{&quot;includeAlertRole&quot;:false,&quot;focusFirstError&quot;:false,&quot;focusErrorSummary&quot;:true}\" data-token=\"a19240af6bc9d44eaff686d0878fc389\">\n<div class=\"frm_form_fields \">\n<fieldset>\n<legend class=\"frm_screen_reader\">Quiz - Feb 25<\/legend>\r\n\r\n<div class=\"frm_fields_container\">\n<input type=\"hidden\" name=\"frm_action\" value=\"create\" \/>\n<input type=\"hidden\" name=\"form_id\" value=\"46\" \/>\n<input type=\"hidden\" name=\"frm_hide_fields_46\" id=\"frm_hide_fields_46\" value=\"\" \/>\n<input type=\"hidden\" name=\"form_key\" value=\"quiz5222\" \/>\n<input type=\"hidden\" name=\"item_meta[0]\" value=\"\" \/>\n<input type=\"hidden\" id=\"frm_submit_entry_46\" name=\"frm_submit_entry_46\" value=\"7239f55efc\" \/><input type=\"hidden\" name=\"_wp_http_referer\" value=\"\/wp-json-v2\/wp\/v2\/posts\/211059\" \/>\t\t<input  type=\"hidden\" name=\"item_meta[317]\" id=\"field_72k1r432\" value=\"\"  data-invmsg=\"Score is invalid\"   \/>\n\t\t<div id=\"frm_field_318_container\" class=\"frm_form_field form-field  frm_required_field frm_top_container vertical_radio\">\r\n    <div  id=\"field_t8ld4432_label\" class=\"frm_primary_label\">1.
