In broad terms, construction details are akin to the fine print of a situation, presenting precise and accurate information that is highly specific in nature. While they might be viewed as superfluous or unnecessary in scenarios where only a broad perspective or summary is needed, details are in fact crucial for obtaining a comprehensive, more exact comprehension of a subject.

Applying this concept in the field of construction, details act as a full-scale representation of a distinct aspect or part of a project. This could refer to any physical structure or component, be it a building, bridge, tunnel, machine, or any other discrete part.

Details in this context are typically illustrated via large-scale drawings, which offer an exhaustive amount of information on certain parts that might otherwise be described more vaguely in general arrangement drawings.

For further insights on this topic, you can explore ‘Detail drawing.’

It is also worth mentioning that suppliers often provide standard details for the components they supply, enabling consistency and adherence to predefined specifications. Similarly, clients or design companies may possess standard details that can be uniformly applied across multiple projects for efficiency and conformity.

Lastly, the concept of detailed design embodies the process of transforming and refining a concept design into a dimensionally accurate and coordinated plan. It meticulously describes all the primary components of a building, elucidating how they seamlessly fit together to form a coherent whole.

Detailed design essentially ensures every part of the construction project is well-defined and fits perfectly into the overall plan.

What is the purpose of construction details?

Construction details serve several significant purposes in the realm of construction and architectural design:

  1. Clarity and Precision: Construction details offer a precise and clear depiction of specific parts of a project. They ensure that every element, no matter how small, is accurately represented, making it easier for architects, engineers, and builders to understand the design and carry out the construction work effectively.
  2. Coordination and Communication: They enable effective coordination and communication among different parties involved in a project, including designers, contractors, engineers, and suppliers. By providing a common reference point, they ensure everyone understands the project’s requirements and expectations.
  3. Standardization: Suppliers and design companies often have standard details for various components, promoting consistency across different projects. These standard details can help maintain the quality and efficiency of the work.
  4. Regulatory Compliance: Certain construction details, such as the Accredited Construction Details (ACDs), help achieve the performance standards required by building regulations. They describe common ways to satisfy these regulations, ensuring the building is safe, sustainable, and compliant with local and national standards.
  5. Comprehensive Design Development: During the detailed design process, these construction details help transform conceptual designs into fully developed, coordinate, and dimensionally accurate plans. They explain how different components of the building interact and fit together, thus helping architects and builders ensure a well-integrated, functional final structure.

In essence, construction details are fundamental to realizing a construction project successfully, ensuring it’s built to the desired specifications, meets regulatory standards, and functions as intended.

Where to find construction details

Locating valuable resources and exemplary cases for construction details can be a formidable task. One can invest countless hours sifting through Google for detail inspiration, yet never truly unearth what you’re seeking.

In an attempt to aid this process, we’ve curated a collection of the most beneficial resources we’ve encountered so far:

Associations, Regulations, and Guidance Accredited Construction Details (ACDs) for Part L: Despite being archived in 2015 and no longer updated, these details still serve as a valuable resource for your studies. They were developed to support the construction industry in meeting the performance standards required for compliance with the energy efficiency requirements of Part L of the Building Regulations.

They provide details for Steel Frame, Timber Frame, Masonry Cavity, and Masonry Internal/External. All of them are downloadable PDFs – an excellent resource for your personal reference library. Visit ACDs here.

Energy Savings Trust Enhanced Construction Details and BRE Certified Thermal Details: The BRE has curated a directory of approved details enabling users to browse through a broad range of thermal junction details. Details, supplied by manufacturers and suppliers, include u-values and additional information, all in PDF format. Visit the BRE Certified Thermal Details here.

Local Authority Building Control (LABC) Approved Details: The LABC registered construction details offer a collection of thermal details designed to reduce heat loss through weak points in the building envelope. Details can be downloaded as dwg files. Visit LABC Approved Details here.

Journals and Magazines Architects Journal Buildings Library: This library features some construction drawings, but access requires a subscription. If you’re a student, your university might provide a username and password for access. Drawings can be downloaded as PDFs. Visit the AJ Buildings Library here.

Detail Inspiration: Detail magazine offers access to over 3,000 DETAIL projects. You can browse the database by type, material, etc., and view the images and details associated with the projects. You need a subscription to access Detail Inspiration, which is offered at a reduced price for Detail magazine subscribers. Visit Detail Inspiration here.

CAD Detail Sites Fastrackcad: This site offers a comprehensive directory of top building component manufacturers who provide CAD drawings and BIM objects of their products. Visit FastrackCAD here. This site offers manufacturer-specific building product information, from SketchUp, Revit, CAD 2D and 3D, to specifications, videos, and images. Visit here.

Manufacturers A vast range of suppliers and manufacturers provide their CAD details for free download. Here are a few noteworthy ones, but there are hundreds more:

Marley Eternit: They offer a large resource center of CAD details, brochures, and technical manuals. Visit Marley Eternit here.

Langley: Langley offers a great range of detail drawings in PDF and CAD format, from built-up roofing, green roofing to liquid coating. You need to sign up to get access to the downloads. Visit Langley here.

Sto: Sto offers downloadable PDF illustrative details, and if you reach out to them, they might provide dwg files as well. Sto specializes in render systems, rainscreen cladding, and external wall insulation. Visit Sto here.

Kingspan: Kingspan provides downloadable PDFs of their insulation products and more. You can also visit the Kingspan Insulated Panels site to download CAD details. Visit Kingspan Product Literature here and Kingspan CAD Details here.

Visqueen – Tanking and Damp proof membranes: It can be challenging to find information about tanking, and DPMs. Visqueen is a useful site for acquiring good details, although they tend to be in PDF format only. Visit Visqueen here.

Velfac – Windows: Velfac offers helpful standard interface details in both PDF and CAD form. Visit Velfac here.

These are just a few examples, but they make a good starting point for exploring construction details.

For some further insight into the wonderful world of construction details, below Eric guides you through the process of designing a sheet of details from inception to completion for a custom, unique fireplace.

He’ll provide insights into all aspects involved in transforming a design concept into a tangible construction project. Eric will talk about how to cultivate and strengthen the design concept using details, the methods he employs to organize his drawing sheets, and how you can leverage code constraints to influence your designs.

He’ll also highlight the importance of using consultants in the design process. Ultimately, you’ll understand how Eric takes an abstract concept about form and experience and converts it into a concrete set of construction details.
