What are Construction Specifications?
Construction specifications are detailed written descriptions that outline the materials, product type, methods, standards and quality requirements. They are contracts between a construction owner and the construction manager hired to deliver a project. Construction specifications are instrumental in ensuring the successful completion of construction projects by offering instructions to contractors and other project stakeholders and facilitating a clear understanding of project expectations and guidelines.
Whether you are a construction industry professional or just entering the field, this article offers guidance to help you become an expert in construction specifications.
In this article, we will review the types of construction specifications and their purpose, who uses construction specifications and specification best practices.
Why are Construction Specifications Important?
Construction project specifications serve an essential purpose in the successful completion of any construction project. They provide a comprehensive and detailed set of instructions that become the legal documents guiding all aspects of the project, from materials and methods to the project quality.
Construction specifications ensure consistency, accuracy and compliance with the project requirements. By clearly outlining the expectations, design requirements and standards for the project, specifications help to avoid misunderstandings, conflicts and errors throughout the construction phase. The project owner and the contractor review construction specifications to incorporate them into the project's legal documentation.
Moreover, construction specifications facilitate effective communication among all project stakeholders, including the project team, contractors and suppliers. They are a common language, allowing everyone to understand and follow the project requirements. To bid effectively and execute the project efficiently, contractors need accurate estimates and project timelines based on details in the construction specification.
By using specification software, project stakeholders can provide specific instructions and guidelines that contribute to the successful completion of the project within the desired scope, quality and timeline. Construction specifications help establish a clear roadmap for the construction process, ensuring that all parties involved are working toward successfully executing the project.
What are the Types of Construction Specifications?
Construction specifications are the backbone of any building project, providing details, standards and guidelines that shape every aspect of the construction process.
There are three main types of construction specifications:
Performance Specifications
Performance specs focus on the project's desired outcomes and functional requirements. They outline the operational requirements of a component or installation and provide flexibility to the contractors in choosing the methods and materials to achieve those outcomes.
Prescriptive Specifications
Prescriptive specifications provide step-by-step details on the types of materials, methods and standards. Prescriptive specs ensure the construction follows industry standards, codes and regulations. With prescriptive specifications, the architect or engineer establishes the regulations, assuming a more significant share of the responsibility in the process. Prescriptive specs depict the final product more precisely than alternative specifications.
Proprietary Specifications
Proprietary specifications provide details on the product type or brand by name. This type of specification can be beneficial for unique or specialized projects requiring specific products. Proprietary specs are frequently employed when pre-existing equipment or installations are present at the side. However, it's essential to understand that referring to a particular manufacturer may deter competition during the bid phase, potentially leading to higher overall project costs.
The choice of specification type depends on the complexity and goals of the project, as well as the preferences of the project team. By selecting the appropriate type of construction specification, contractors and project teams can ensure that the project meets the desired standards and requirements.

Who Uses Construction Specifications?
Construction professionals, including architects, engineers, contractors and various stakeholders, play a pivotal role in the development of specifications throughout a project's lifecycle. Their collective efforts guarantee that specifications accurately represent project needs, adhere to industry standards and align with the project's design and construction objectives.
Feedback from construction industry professionals also helps refine future specifications, enhancing efficiency and project outcomes. Overall, the involvement of construction professionals ensures that specifications are well-executed, facilitating the successful coordination of construction documents while meeting client expectations and industry standards.
What are the Key Components of a Good Specification?
Writing a specification involves careful planning and attention to detail. Here are some tips to help you write a great specification.
- Understand the Project: Before writing the specification, thoroughly understand the project requirements, objectives and scope. Consult with the design team, project managers and stakeholders, review project documents and gather necessary information to ensure clarity and accuracy. Every successful project begins with a strategic predevelopment process before a construction worker or equipment arrives on-site.
- Be Clear and Concise: Use clear and concise language to communicate your requirements. Use precise terminology and organize the specifications using a standardized format, including sections and subheadings for easy reference. Building specifications give construction teams a detailed overview of project work, required performance and product selections.
- Include Relevant Details: Include all necessary details to describe the material requirements clearly. Specify materials, products, dimensions, performance criteria, installation methods and other specific requirements. By incorporating specifications early in the project lifecycle, performance requirements are established from the outset, reducing risk.
- Be Specific But Flexible: Provide specific requirements while allowing for flexibility and innovation. Focus on desired outcomes and performance expectations, allowing contractors and suppliers to propose suitable solutions within the framework.
- Reference Applicable Standards: Reference your specification's relevant industry standards, codes, regulations and best practices. Using standards helps quality control, ensures compliance with accepted norms and facilitates consistent project quality.
- Implement a Master Guide Specification: A master guide specification product like MasterSpec streamlines the development of specifications by providing standardized templates and language, ensuring consistency and accuracy across projects. They also offer comprehensive guidance on industry best practices, saving time and effort while enhancing the quality of specifications.
- Use Proper Formatting and Organization: Use consistent formatting and organization throughout the specification: number sections and sub-sections for easy reference. Include a table of contents and a clear heading to help readers navigate the document. The MasterSpec list of divisions as part of the master guide specification product, MasterSpec, offers highly detailed and specific construction specifications tailored to individual elements of a project. MasterSpec is often preferred for its standardized format, saving architects and engineers time by providing pre-written, industry-standard specifications for various construction elements.
- Review and Revise: After writing the specification, review it carefully for accuracy, clarity and completeness. Revise as needed to address any inconsistencies or gaps. Seek input from relevant stakeholders, such as architects, engineers or consultants, to ensure the specification meets the project requirements. Contractors frequently utilize specifications in conjunction with architectural drawings. Following project completion, office masters can integrate best practices and lessons learned, enhancing efficiency, ensuring quality and maintaining project consistency.
