A simple drawing is not enough to build a safe, beautiful structure that meets building codes and stays within budget. This is where professional drawings in the form of drafting services step in, with the right dimensions, elements, and lines.

What is Drafting?

Drafting—also called technical drawing—is the process of creating accurate representations of buildings, houses, or objects for architectural, engineering, or technical purposes. This work is done by a draftsman or draftsperson or, less commonly, a building drafter or drafting officer.

You will require drafting services if you want to build, renovate, or remodel a complex or structure. The drafting will need to be ready for the contractor. Even if you already have an existing design, you will need drafting services to develop a blueprint for the whole construction team.

Drafting typically includes a main view, a top view, and a side view of the structure or object, as well as objects that are drawn to scale. The drawings are highly detailed. While they are at times used in engineering, they are more common in the architectural sector.

Recent advancements in digital drafting tools and software, such as Building Information Modeling (BIM) and Computer-Aided Design (CAD), have significantly enhanced the accuracy and efficiency of the drafting process.

What is Architectural Drafting?

Traditionally, drafting was done on paper with protractors, pencils, and rulers. However, in recent years, Computer-Aided Design (CAD) has become the norm, in addition to T-squares and set squares.

In architectural drafting, draftspeople are employed to draft building designs, showcasing dimensions, configurations, specifications for appliances, doors, lights, windows and other features, and external details such as fencing, roofing and driveways.

CAD is generally far quicker and more accurate than traditional drafting and can be stored electronically. Drafting services often use ArchiCAD, AutoCAD, SolidWorks, and Revit to create plans and/or 3D models.

Some other tasks that an architectural drafter may undertake include:

• Developing sketch plans

• Conferring with local government and making sure that by-laws and codes are followed while creating project documents

• Assisting with preparing building specifications to obtain approval

• Outlining quality and quantity of materials needed, including timeframe, labor rates, and cost

• Site inspection and field surveys

• Communication and coordination

• Updating proficiency in CAD, BIM, and more tech.

When working with an architect, architectural drafters are sometimes also referred to as architectural technicians, building associates, or architectural draftspeople.

Benefits of Drafting Services

High-quality CAD drafting makes it possible to calculate the project’s budget before it is even implemented, thanks to advanced features such as automated cost estimation tools and material quantity takeoffs. These features provide real-time cost analysis and budget forecasting based on detailed drawings.

Without a conscious and professional approach towards blueprints, construction errors can cost lives. Still, modern CAD systems incorporate advanced simulation and analysis capabilities, including stress testing and safety simulations, which help identify and mitigate potential risks before construction begins.

Based on architectural drafting, financial specialists can plan the procurement and working process by estimating the consumption of labor and materials and recent updates in CAD software enable more precise forecasting by using parametric design features and BIM integration.

Types of Drafting in Architecture

There are some architectural drafting types that you should be aware of if you are planning to hire CAD drafting services.

1. Architectural Drafting

Architectural drafting includes floor layouts, sections, elevations, construction site plans, and axonometric and isometric views of a structure. Essentially, these are the drawings required at the initial stages of the project. Before construction starts, the plans are shown to investors and clients for approval.

2. Interior Drafting

After the interior design is approved by the client, interior drafting or detailed interior drawings are made for construction or renovation. This is a 2D graphic representation of the interior project’s layers.

The most important interior drawings include:

• Furniture layout

• Existing walls layout

• Electricity plan

• Floor coverings layout

• Plumbing plan

• Ceiling plan

• Wall elevations & cross-sections

When it comes to renovation projects, the interior drafting showcases placements of elements such as plumbing and electrical appliances so that the renovation will not disrupt existing systems.

3. Furniture Drafting

The parameters of the relevant rooms should be taken into account so that the final result includes furniture that maximizes space. This is especially crucial when planning installed storage systems such as walk-in wardrobes.

4. Structural Drafting

Structural drafting can refer to either of the following:

• Drawings of steel buildings, towers, bridges, dams, and other similar projects

• A building’s support system, such as beams, columns, and foundations

• The drawings include structural details, which require the skills of a licensed engineer. Hence, structural drawings need to be stamped and signed by a professional engineer (PE).

Structural drawings will vary with each project but should generally include the following information:

• North point

• Framing details

• Dimensions of concrete structure on site

• Locations of all holes, fixings, cavities, chases, and other elements that have an effect on concrete mixing

• Plans, elevations & sections showcasing dimensions, design & levels of concrete elements

5. Electrical Drafting

These are technical drawings of electrical wiring and electrical systems. It can include everything from wiring diagrams for apartment buildings to schematics of automotive electrical systems.

A complete set of electrical drawings for a large project would usually consist of:

• Control writing diagrams

• Single-line diagrams

• General arrangement diagrams

• Power-riser diagrams displaying panel boards

• Plot plan with building location & outside electrical wiring

• Floor plans displaying locations of electrical systems on each floor

• Schedules

6. Floor plans

These blueprint drawings provide a horizontal view of each floor of the building, showing the layout of rooms, walls, doors, and other elements. They also include detailed dimensions, spatial relationships, and design elements specific to each floor.

They serve as a key communication tool between architects, designers, contractors, and clients, ensuring everyone has a clear understanding of the design using CAD, BIM, and floor plan development.
