The requirement specification describes all of the client\u2019s requirements for the deliveries and services of a contractor. A clear definition of the project to be procured is the prerequisite for this document and the tender.<\/p>

<\/i>Clear requirements<\/strong>All requirements for delivery and service in one place.<\/span><\/div>
<\/i>GMP & GAMP<\/strong>Standards and ambient conditions defined from the outset.<\/span><\/div>
<\/i>Including interfaces<\/strong>Optionally including the associated interface descriptions.<\/span><\/div><\/div>

First, it must be clarified which standards and ambient conditions apply to the tender \u2013 for example GAMP or GMP. To define the process engineering project clearly, we then divide it into individual phases.<\/p>

Phases and contents of a requirement specification<\/h2>

The key contents of a tender include:<\/p>

  1. 1<\/span>Basic parameters<\/strong>Definition of the basic parameters in the preliminary project (planning phase 1).<\/span><\/li>
  2. 2<\/span>Draft design<\/strong>Basic engineering<\/a> with process design (planning phase 2).<\/span><\/li>
  3. 3<\/span>FEED & tender<\/strong>Tender documents, interface definitions<\/a> and the specification for approval (phase 3).<\/span><\/li>
  4. 4<\/span>Detail engineering<\/strong>Enquiry and procurement<\/a>.<\/span><\/li>
  5. 5<\/span>Functional specification<\/strong>The contractor prepares it based on the approved tender documents.<\/span><\/li>
  6. 6<\/span>Construction supervision<\/strong>Supervision of the construction phase<\/a> at the supplier; the client approves the quality documents.<\/span><\/li>
  7. 7<\/span>FAT<\/strong>Factory Acceptance Test \u2013 acceptance at the supplier\u2019s works.<\/span><\/li>
  8. 8<\/span>Installation & commissioning<\/strong>Installation and commissioning of the plant on site.<\/span><\/li>
  9. 9<\/span>IQ<\/strong>Installation qualification<\/a>: verification against the order documents.<\/span><\/li>
  10. 10<\/span>OQ<\/strong>Operational qualification<\/a>: verification of the intended functionality.<\/span><\/li>
  11. 11<\/span>PQ<\/strong>Performance qualification<\/a>: proof of the required performance.<\/span><\/li>
  12. 12<\/span>SAT<\/strong>Site Acceptance Test \u2013 acceptance at the customer\u2019s site.<\/span><\/li><\/ol>

    Frequently Asked Questions about requirement specifications for process plants<\/h2>

    What is a requirement specification?<\/h3>

    The requirement specification (user requirement specification) describes all of the customer\u2019s requirements for the contractor\u2019s deliveries and services. It is the basis for tendering, offer comparison and the supplier\u2019s functional specification.<\/p>

    What is the difference between a requirement specification and a functional specification?<\/h3>

    The requirement specification defines what the customer requires. The functional specification is prepared by the contractor based on the approved tender documents and describes how the requirements will be met.<\/p>

    Which phases should a requirement specification cover?<\/h3>

    From defining the basic parameters through basic engineering, FEED, detail engineering and procurement to construction supervision, FAT, installation, qualification (IQ, OQ, PQ) and SAT at the customer\u2019s site.<\/p>

    Which standards are relevant?<\/h3>

    Depending on the project, for example GMP and GAMP as well as the respective environmental conditions. They must be clarified before tendering.<\/p>
