What Is a Specifier in Construction?

A construction specifier is responsible for generating detailed technical specifications about a project’s materials and equipment. They are the ones who must advise project stakeholders about what materials to acquire to meet design, quality, safety, and sustainability requirements.

Professional specifiers have a wealth of knowledge in construction, product manufacturing, installation, and maintenance. They are experts in all types of construction materials and methods, making them invaluable assets in building cost-effective, high-quality structures.

Specifiers are especially important in large construction projects where different teams design components that must fit together for the project to work. Their job is to review and integrate all these elements in an understandable and technically accurate way. They collaborate with stakeholders like architects, engineers, contractors, and clients, outlining detailed specifications to guide the project. Construction specifiers are vital to the success of a project because they:

  • Ensure fair and accurate costing by detailing all materials and workmanship
  • Set clear expectations for vendors, contractors, and clients
  • Provide a single source of truth for construction products and materials
  • Set appropriate quality and workmanship standards that are independently verifiable

A good specifier also supports the cost estimation and bidding processes by providing clear and detailed specifications to limit misinterpretation and errors that can cause delays or lead to cost overruns during the construction phase.

What Does a Construction Specifier Do?

Top four construction specifier responsibilities
Construction Specifier Responsibilities

A specifier creates and updates specification documents to complement design drawings that define the materials and installation methods for a construction project. Construction specifications documents are prepared before construction begins to guide the building team and other stakeholders about how the project should be built. They provide crucial details about how the different materials and equipment should be used, as well as workforce guidelines. The main goal is to provide detailed information to supplement the architectural drawings and ensure the project’s quality and regulatory requirements are met.

Here’s a more detailed look at construction specifier responsibilities:

Evaluate project requirements

Specifiers need to carefully study project requirements to develop clear specifications and provide advice and effective feedback. They collaborate with the design team to pick materials and technologies that align with quality and regulatory requirements. They apply this knowledge throughout the project to evaluate and ensure work quality.

Develop specifications

Writing specifications is obviously one of the key tasks associated with this role. Specs must be detailed, specific, and clear, as different teams, especially contractors and subcontractors, use them as guides for their work. Specs are also utilized during quality inspections to ensure the work complies with agreed-upon requirements. Specifiers collaborate with architects, engineers, and other disciplines to produce the most accurate and detailed specs.

It’s important to note that in large construction companies, the specifier is often considered a senior position that is not in charge of the actual writing of specs – a spec writer is hired to fulfill that role. However, for the purpose of this post, we will consider this part of the overall specifier role.

Support the procurement process

The specifier supports the construction procurement process, researching and evaluating the durability, performance, costs, and environmental impact of materials to advise procurement teams on the best ones to purchase. They also assist in the construction bidding process by preparing the specifications in the tender package and helping compare the different bids to select the most appropriate ones for the project.

Manage specifications throughout the project

The role of a construction specifier goes beyond selecting materials and advising building methods with their responsibilities expanding throughout the project lifecycle. They review and challenge the decisions of various stakeholders to ensure that quality, safety, health, and building requirements are met while keeping the project time- and cost-effective. If a change of any nature happens during the project, specifiers must update the documentation and notify the different teams to ensure everyone remains on the same page.

However, the average yearly salary to date that these professionals can expect to make if they meet the basic requirements are: $85,523 in the US; and £38,730 ($51,989) in the UK.

How to become a construction specifier?

The path to becoming a construction specifier combines education, training, and experience. The educational path starts with a bachelor’s degree in a relevant field, such as architecture, construction management, or engineering, lasting two to four years. Around the third year of your degree, you can start applying for internships or apprenticeships at an architectural firm or construction company, where you can start drafting specifications and learning about materials, equipment, regulations, and all the ins and outs of the field. You can also apply to be a helper in an architectural firm, a construction laborer, or for an administrative role in a manufacturing company or construction supplier, as these experiences will help you gain the skills and knowledge needed to develop professionally.

Graduates can start applying for jobs in the field although they may have to start with a smaller role and build experience to become a recognized construction specifier due to the skills and experience requirements of the position. Most companies look for at least eight to ten years of previous experience to meet the complexity of the role.

You can also pursue additional certifications to differentiate yourself from other candidates. One of the most recognized certifications for specifiers in the US is the Certified Construction Specifier (CCS) program offered by the Construction Specifications Institute (CSI). In the UK, specifiers can apply for a range of certifications, including becoming a Chartered Architectural Technologist (MCIAT) or getting a Construction Skills Certification Scheme (CSCS) certification, to demonstrate their knowledge in design and construction.

What is the difference between a construction specifier vs spec writer?

It depends – the definitions change from company to company and from project to project. Some say specifiers are senior consultants across the entire project who offer advice about materials and product selections to all disciplines, and define spec writers as solely responsible for the spec writing process, following the guidelines of the design team or the specifier. Others consider these two roles as one, as the specifier has the technical expertise to write clear, concise specs.

How do specifiers manage specification changes during a project?

Incorporating and controlling changes accurately and efficiently is one of the most important responsibilities of this position. Changes can occur as a result of client modifications, design revisions, unexpected site conditions, material shortages, regulatory updates, and many other issues throughout the course of the project. Specifiers must update specifications accordingly to implement changes, and understand the overall impact on the project.

Centralized document management databases and a formal construction change management process are two of the basic elements required to manage specification changes effectively. Specifiers must use their strong collaboration skills to gain alignment on the impact of changes, ensure proper approvals are obtained, and communicate changes to other stakeholders. This communication is especially important for procurement teams and contractors who must then describe the impact of specification changes to suppliers and subcontractors.

Do construction specifiers visit the construction site?

The specifier role is typically an office-based position with a heavy reliance on computers and technology to complete tasks in a timely manner. However, it is not unusual for them to spend time visiting the construction site – the frequency and purpose of these visits will depend on the specific role and project. Even if it’s not strictly required, a visit can be useful for them to understand the project scope and meet with other stakeholders. Other reasons for periodic site visits might include:

  • Comparing actual materials and workmanship to specifications
  • Discussing changes and material substitutions with contractors and other team members
  • Advising on complex installation processes and other methods specified
  • Helping to review the quality level of materials and products as they arrive

Regular site visits also give specifiers firsthand experience that helps them understand how their written requirements and instructions are interpreted in the field. It allows them to improve their methods over time and make future specifications more understandable. They can also learn practical lessons on industry best practices from experienced specialists, construction foremen, and other stakeholders they don’t interact with in the office.   

How does BIM integrate with specification writing?

Building information modeling (BIM) is a process used to manage all elements of the design and construction process more effectively by moving key aspects of a project into the digital realm. This includes detailed 3D design models layered with cost, quantity, schedule, material, and sustainability data to improve efficiency and decision- making. BIM models can also be linked to the specification writing process to automatically connect design requirements to the documentation set, and ensure all specs are aligned with the features, sustainability objectives, and cost information. 

BIM improves visibility and efficiency by making it easier for specifiers to visualize specific elements of the design in 3D space to ensure their written specifications correctly reflect the design intent. Any conflicts or misalignments between design elements and specs are quickly identified to avoid rework or change orders during construction. BIM models also provide a convenient way for specifiers to collaborate with engineers, architects, and other specialists as they review a common cloud-based model that conveys all project information.

What are the benefits of using cloud-based specification tools?

BIM is just one example of cloud technology improving efficiency and collaboration during the specification process. Cloud-based tools and software provide many other benefits that include:      

Centralization

Cloud solutions allow all specifications to be stored in a single online repository, and accessed and managed from anywhere. Centralization minimizes the risk of lost or disorganized documentation while ensuring everyone is able to find the latest information quickly, even from construction sites or other remote locations.

Version control

Traditional software tools sometimes make it difficult to eliminate obsolete specifications while getting new information distributed quickly. Cloud-based software simplifies version control by tracking changes automatically and only presenting the most current revision to users. This allows specifiers to work on changes and new releases without worrying about mix-ups or confusion over the correct version. 

Scalability

Today’s complex construction projects exceed the size and scope of projects from previous generations many times over, along with the number of stakeholders and extended team members requiring real-time access to information. The nearly unlimited storage and computing power found in the cloud removes previous limits on the number and size of files, allowing companies and projects to grow without worrying about new hardware investments or system upgrades.    

How do construction specifiers support sustainability goals?

Sustainable construction goals for buildings and other structures, including those established to obtain prestigious LEED or BREEAM building certifications, can only be met when each element of the project is evaluated on its carbon footprint, energy efficiency, resource consumption, and other sustainability metrics. A construction specifier factors these in as they create new specs, advise design teams, and manage changes.

For example, sustainable specs reduce waste by calling for more durable materials that are locally sourced to minimize carbon emissions from transportation. Specifiers must consider occupant health factors like air and water quality as they select materials with low volatile organic compounds (VOCs) and readily available health product declarations (HPDs). Specification management software makes it easier to expand these limits and requirements across all spec types.

Will AI replace construction specifiers?

Artificial intelligence can potentially replace many repetitive, manual activities in construction, such as material handling, site monitoring, design analysis, supply chain management, and reporting. AI only makes these processes safer and more efficient, but highly skilled human workers are still needed to monitor progress and ensure tasks are performed correctly.

As we redefine the role of a specifier in construction over the next decade, we are likely to see a pattern of AI used to streamline basic tasks and eliminate errors, while human specialists continue to collaborate with other experts, research new methods and technologies, and oversee AI results to prevent the benefits of technology from introducing new problems. AI can also be used to generate the basic spec content that makes up the majority of these documents, while automatically scanning project requirements and codes and cross-referencing related documents to ensure alignment. Human workers will use this added efficiency to take on more tasks, develop new methods and tools, and resolve challenging issues in the field.    

What is the link between specifications and cost estimation?

Specifications and cost estimation are very closely related, since estimators rely on the detailed information contained within the specs to determine the expected material and labor costs. While the quantity takeoff process is used to determine how much of each material type is needed, the specifications define the levels of quality and customization needed to determine the precise unit cost. When combined, this information leads to accurate and reliable cost estimates.  

On-screen takeoff capabilities that automatically pull quantity information from either 2D or 3D design files, and BIM software platforms that combine design, cost, and quality specifications, help to integrate these two processes and minimize manual information transfers and calculation errors that lead to inaccurate estimates.

Final Thoughts

Construction specifiers are experienced professionals who use their extensive knowledge to help the project reach its quality goals. They learn to review every detail, identifying areas for improvement and suggesting innovative and cost-effective solutions. They are also experts on all things related to construction materials and can provide sound advice about which material is best based on the project’s requirements. Specifiers are also responsible for drafting the specifications to capture all requirements in an understandable and applicable way, contributing to a collaborative environment that increases productivity.
