Specification experts Dikesh Pattni and Marc Ameryckx from ASSA ABLOY's European team break down what door specification really means in construction. They cover the difference between prescriptive and performance-based specifications, why reusing specs from previous projects is risky, and what happens when vague specs like "steel door" lead to costly mismatches on site. With real-world examples, including a contractor who installed a €50 electric strike when the owner expected a multi-point motor lock, this episode makes the case for involving specification experts early in the design process. Practical guidance for architects, contractors, and building project teams.
