Many designers notice a specification only when a product choice goes wrong. Yet a drawing cannot carry every requirement about materials, testing, workmanship and performance. A good specifications writer translates design intent into instructions that other teams can use and check.
The AIA’s descriptions of architectural positions include roles that prepare reports and specifications. Its 2026 research on specification practice shows that architects remain central to researching and evaluating products. Neither source says the same person must write every section; practice models vary.
See the job in one detail
Choose a wall, roof or flooring assembly from a project you know. A drawing may show location and geometry. The specification may need to describe performance, compatible products, preparation, installation, testing and closeout requirements. Now ask what happens if the drawing and spec disagree. Who resolves it, and how is the correction issued?
That is the work: connecting a design decision to a coordinated, buildable and reviewable set of documents.
Test whether you enjoy the underlying skill
Read a product data sheet and write five questions before selecting it: Is it suitable for the assembly? What conditions invalidate the warranty? What substrate or environmental limits apply? What maintenance is required? Which performance claim is independently evidenced? Do not choose a product from marketing imagery alone.
Next, compare the drawing note with the relevant specification section. Look for a contradiction, omission or ambiguous term. Explain the consequence in plain language. If that exercise interests you more than making another rendering, specifications may be a real specialism to explore.
Build a portfolio of judgement
Do not publish a client’s proprietary specifications. Create an anonymised example showing a problem, the conflicting requirements, the sources you checked and the revision process. A hiring manager wants to see how you reason, coordinate with consultants and keep versions controlled. Name what you authored and what a senior professional approved.
Ask what kind of role it is
Some firms need a dedicated specification writer; others spread the work across project architects and technical staff. Ask whether the role writes sections, reviews consultant input, maintains a master library, researches products or helps resolve construction queries. Also ask how the firm trains staff and who holds professional sign-off.
A small specification exercise
Take a simple building element from an approved project or a hypothetical design. List the performance you need, the products or systems that could meet it, the interfaces with nearby work, the tests or submittals that would prove compliance and the person who will review them. Then compare this list with the drawing notes. Where do the two disagree? A beautiful detail can still fail if the written requirement asks for a different material or leaves the installer to resolve an important junction.
Do not copy a master section and assume it fits. A master is a starting point containing choices that must be edited for the project. A useful specification tells the project team what is required, what can vary and how acceptance is judged. That requires research, coordination and the discipline to remove irrelevant language.
In an interview, ask whether the firm expects you to author project sections, edit a master library, coordinate consultant specifications or review submittals during construction. Ask who makes technical decisions when documents conflict. Those answers reveal the learning path and level of authority behind the title.
AIA’s drawing and specification guidance makes the core point: documents should be understandable to the people who use them. A strong spec writer notices where an important requirement could be misunderstood.
Follow one requirement through the project
Choose an approved wall assembly or a clearly fictional one. Write a one-sentence performance requirement, then trace it through drawing, schedule, specification and submittal review. Where does the team establish the required performance? Where does it identify an acceptable product or system? Who checks a proposed substitution? If the answer changes between documents, you have found a coordination issue, not just a typo.
Practise explaining the issue to two audiences. For a designer: “This substitution could change the junction and the required rating.” For a contractor: “The current section does not state the acceptance evidence; we need the agreed test or certification before approval.” Replace these examples with the real project’s requirements. The skill is turning a technical inconsistency into an actionable question without pretending to approve what lies outside your authority.
To explore the career, ask a specification writer to show how one project section differs from the office master. What was deleted, what was retained and why? A role that only copies templates will teach less than one that connects product research, design intent and construction feedback. Keep a dated record of what you wrote, what a senior colleague checked and what a later site question taught the team. That is a credible technical portfolio.
