REQUIREMENTS
TLE- IA : TECHNICAL DRAFTING

2. The architectural working drawings and the specifications
are the most important parts of the documents constituting
the contract. Information on the designs, locations, and
dimensions of the elements of a building is found on the
architectural working drawings while information on the
quality of materials and workmanship is found in the
specifications. A good architectural working drawing gives
the contractor the exact information he needs. It should be
clear, simple, and orderly arranged, and accurately drawn so
that scaled measurements will match with dimensions.
ARCHITECTURAL WORKING DRAWINGS

3. The finished drawings made by the architect, or draftsman
and used by the contractor are called architectural working
drawings. The architectural working drawings, together with
the specifications and the general conditions, form the legal
contract between the owner and the contractor. Since the
working drawings are a major portion of the contract
documents, they should be very carefully drawn.
ARCHITECTURAL WORKING DRAWINGS

4. Elements of Architectural working drawing.
A complete architectural working drawing of a house generally includes the following:
1. Architectural sheets
a. Sheet # 1 - Title page and index (Exterior perspective, site
development plan or plot plan, and vicinity map or location
plan is often included in the plan).
PERSPECTIVE is the view as seen by the eyes or it shows the
appearance of the finished building. This drawing represents the
actual form of the proposed building. (See perspective on the next
page).

5. * SITE DEVELOPMENT PLAN is the outline and measurements of the
proposed building and its placement on the property. it shows the
position and the location of the building with property line, setbacks,
approaches, grade contours, landscape, and other pertinent data in
relation to the site. A site development plan is drawn using a scale not
smaller than 1:200 meters. (seesite development plan on the next page.)
* LOCATION PLAN is the top view of the site or lot where the proposed
house will be built. It shows the position of the house inside the lot, the
number of adjacent lots, streets, or lanes before or beside the lot, and the
North sign. The location plan is usually located near the title block. The
main line symbol of the North sign is generally parallel to the side border
line of the drawing paper and points upward.

ARCHITECTURAL ABBREVIATIONS:

15. Architectural Symbols
Familiarizing all the architectural symbols is a prerequisite
for all students in architecture and drafting technology
programs considering that their future works will be on the
architectural activity. It would be difficult for them to interpret
drawings or blueprints unless they have familiarized all the
architectural symbols.

a. Doors and windows symbols that are shown in the floor plan
