Types of Drawings Dr. Muauin Qasem Jawabrah 1st lecture- 2nd week fall semester-2015

Types of Drawings: 

   

Engineering drawings Architectural drawings Technical drawings As built drawings Shop drawings

•Types of Drawings: 1. 

Engineering drawing: Definition :A schematic representation of a building, object , or component made according to defined conventions and projected to serve in the construction or fabrication of the thing depicted.



Engineering drawings are frequently used to describe public works projects, such as : 

bridges, highways, and dams.

•Types of Drawings: 2. 



Architectural drawing Definition A sketch, diagram, plan, or schematic used to design, construct, and document buildings and other structures. The drawings may be used to indicate the overall appearance, inside or outside the structure, or they may be used to indicate precise measurements and other details for construction. Drawings, especially those for construction purposes, may be issued as a set, with different sheets indicating different types of construction (electrical, mechanical, plumbing).

•Types of Drawings:  



As-built drawing Definition Architectural drawings that reflect changes made during the construction process, recording differences between the original design and the completed structure. As-built drawings are based on design drawings used during construction, where measured drawings are usually made long after construction is completed and no design drawings exist

•Types of Drawings:  

Technical drawing: Definition A graphic using lines and symbols that follows specific conventions of scale and projection, typically used in architecture, construction, engineering, or mapping

•Types of Drawings:  



A shop drawing: Definition It is a drawing or set of drawings produced by the contractor, supplier, manufacturer, subcontractor, or fabricator. Shop drawings are typically required for prefabricated components. Examples of these include: elevators, structural steel, trusses, pre-cast, windows, appliances, cabinets, air handling units and millwork.





Shop drawings are not produced by architects and engineers under their contract with the owner. The shop drawing is the manufacturer’s or the contractor’s drawn version of information shown in the construction documents. The shop drawing normally shows more detail than the construction documents. It is drawn to explain the fabrication of the items to the manufacturer’s production crew. The style of the shop drawing is usually very different from that of the architect’s drawing.

Architectural Drawings used for: Building elements seen in true size, shape, orientation . ”scale” Describe form & construction of building component. It is the base drawings for other construction works.” electrical, sewage, mechanical…”

Preparing the architectural drawings: 

Site plan



Plans 

Elevations 

Sections

Preparing the architectural drawings: 

The site plan: is a view looking down at a building from above, illustrating its location & orientation on a plot land & providing information about the site’s topography, landscaping utilities ,and site work.



The importance of site plan: 

It illustrates the existing natural & built features.

Preparing the architectural drawings: 

The floor plan: is a view looking down/ a horizontal plane is cut through a building from above about 1.5m, illustrating it’s the horizontal dimensions of a building spaces, the thickness & construction of vertical walls & columns that define these spaces.

 1.

The importance of plans: Define the spaces & its functional relationship. Illustrates places of openings (doorswindows). Finishing. Entrance (main- secondary)

Utilities (stairs- elevators- mechanical roombaths- stores….) Structural system: 1. 2. 3.

7.

R.C, steel, bearing walls… Columns, beams,… Thickness of walls (exterior & interior)

Measurement and cost (quantity survey)

Preparing the architectural drawings: The building section: is a vertical pane cut through a building. Or: it is a drawing of interior & exterior partitions and roofs and ground floor in addition of interior elevations seen beyond the plane of cut.

The importance of The building section: Illustrate building construction. Technical implementation (precast- prestress…). Types of slab (roof plate) solid slab, hollow block, flat slab…). Building material (block, stone, concrete,…). Height of the building and levels. Details and finishing. Measurements.

Preparing the architectural drawings: 

Building elevations: is views of a building’s exterior perpendicular to the principle vertical surfaces.
