Construction drawings are the blueprints required for constructing any building or starting any construction. Construction drawings are basically all the architectural documents that guide the construction phases of a project.
They form the foundation for the successful execution of any project. Therefore, understanding and mastering construction documents is important for efficient project management.
In this blog, we will discuss everything a construction professional needs to know about these documents so that they can execute the project efficiently.
Construction documents, also known as contract documents or construction drawings, provide information to the project stakeholders regarding the design of the building, the quantity and type of material required, and the construction methods. In other words, these documents communicate the design intent and requirements to the architects, builders, contractors, or owners involved in the construction.
As uncovered in the previous section, these documents provide detailed information about the design, materials, and construction methods required for a building project. Construction project documentation serves as a roadmap because it documents specifications for every aspect of construction. For example, these documents help contractors and builders accurately estimate the cost of the project. By reviewing the documents, they can determine the quantity and type of materials that will be needed, as well as the labor and equipment requirements.
Construction documents also play a crucial role in obtaining building permits and ensuring compliance with safety standards. When a construction project is proposed, the local building department or regulatory authority will typically require the submission of construction documents as part of the permit application process. The building department or regulatory authority will review the construction documents to ensure that they comply with all relevant codes and regulations. This review may include a checklist for structural integrity, fire safety, accessibility, energy efficiency, and other factors. If the construction documents are found to be in compliance, the building permit will be issued, and the project can proceed.
Construction documents typically fit into all the stages of a building project.
In the first phase, which is the schematic design phase, drafters provide rough sketches of different design options to the owners.
The next stage of the process is typically referred to as design development. During this stage, the architect refines the schematic design concept and develops more detailed drawings and specifications. The design development phase is where the architect will typically begin to coordinate with other design professionals, such as engineers and consultants, to ensure that the design is consistent and meets all relevant codes and regulations.
The construction documentation stage, the third phase of a building project, is where the designs are finalized with notes and specifications for the project's contractors or owners.
The fourth stage, the bidding phase, will use information gathered from the final construction sets.
The final stage of the architectural design process is the construction phase. During this stage, the construction documents are used by the contractor, builder, and other parties involved in the construction process to construct the building project.
Construction documents consist of different types of sheets. The major ones include:
These encompass a range of drawings such as the cover page, general drawings, building and zoning code analysis, sustainability standards, and life safety plans.
The most common example of construction documents is a cover page. The cover page or cover sheet includes information on the project name, contact information, engineering consultants, information about the property, building type, etc.
This plan or construction document offers an extensive illustration of the entire project location, including the positions of the building, roads, and utilities such as water and electricity, among other elements.
This plan outlines the areas and components of the building that need to be removed or demolished. It shows the current state of the building, the existing structure, the floor plan, elements that need to be protected along with the parts that need to be removed.
Foundation plan provides a detailed view of the building's foundation, including the location, size, and type of footings, as well as any necessary reinforcements or drainage systems.
This plan shows the layout and arrangement of spaces within the building, including walls, doors, windows, and built-in elements such as cabinets or counters.
A framing plan shows the composition of the building's framing, including the size and spacing of studs, joists, and rafters, as well as any necessary supports or bracing.
A roof plan shows the roof's layout and structure, including its form, inclines, and positioning of features such as skylights and vents.
Interior elevation drawings include information on interior walls, built-in furniture, height of various elements, etc. These also include information that is typically not covered by other plans like floor plans; this may include decorative trim, drawers, chandeliers, etc. Exterior elevation plans cover information on the overall design, such as roof height, windows, doors, and decks.
The landscape architecture sheets are not the architectural sheets. They provide detailed plans, sections, and other information about the construction of various landscape elements for contractors.
These sheets contain notes and details from the civil engineer hired for the project. They may include grading plans and other related information.
Architectural construction documents are very detailed drawings of a building's components, such as its sections, elevations, etc.
These construction documents outline the structural plans and calculations for the building.
These sheets include drawings that showcase the locations and sizes of various inbound and outbound water supplies. They also provide a detailed plan for each level of the building, including every drain, faucet, and pipe, to define the overall functional plumbing system.
Mechanical engineers construct these documents, which include the location and sizes of mechanical equipment, such as exposed or concealed ductwork, vents, thermostats, heating/cooling units, etc.
These sheets provide the exact locations of electrical outlets, cables, fixtures, switchboards, and other electrical items in the building.
This is not a type of document in itself but a collection of multiple documents, such as site plans, foundation plans, floor and framing plans, and interior and exterior elevation drawings. These are basically used to obtain building permits from authorities.
Construction documents are typically created in standard architectural sheet sizes. Different jurisdictions have different requirements for creating these sheets. However, there are some common standard sheet sizes that you may find:
