DRAFTING

STRUCTUR AL LAYOUT &

 What to Know  What to Process  What to Reflect &

Understand  What to Transfer

Objectives: At the end of this module, you are expected to:  draft foundation plans  draft structural floor and

roof framing plans

Introduction: Every

structure needs a foundation. The function of a foundation is to provide a level and uniformly distribute support for the structure. The foundation must be strong enough to support and distribute the load of the structure.

Skills Assessment Skills in Architectural Job Requirements I know how to draft foundation plans.

I can draft structural floors and roof framing

This lesson is designed…

to define the FOUNDATION and FOUNDATION PLAN; to identify the different types of foundation; to draft a sample foundation plan;

Skills Assessment Skills in Drafting Foundation Plans I know how to indicate locations of wall footings, footing and columns in the floor plan.

I can draw larger scale details of wall footings and columns.

Design of Foundation

The design of a foundation is solely based on site investigation .

SITE INVESTIGATION- is the result of determining the soil surface and the condition of the soil.

ACTIVITY In a ¼ manila paper, draft a sample FOUNDATION PLAN of the Computer Laboratory 2.

FOUNDATION PLAN OF COMPUTER LABORATORY 2

Use . the scale of 1:100mts.

Draft the LENGTH (16.0m) & the WIDTH (8.0m) of the floor plan using the EXTERIOR WALL SIZE (0.15m). 16.0 m 8.0 m

FOUNDATION PLAN OF COMPUTER LABORATORY 2

.

In every 4.0 meters of the floor plan, put a SQUARE COLUMN (0.2m X 0.2m) on both sides.

Technical Terms Encountered in Drafting Foundation Plans

Foundation - is the part of the building below the surface of the ground which is sometimes called the substructure.

Footing - is an expansion at the lower end of a wall, pier or column to distribute the load into the ground.

External Reference is a DWG, DWF, DWFx, raster image, DNG, or PDF file incorporated into a drawing for reference only.

Layer Filters - are settings that screen out, or filter, layers you do not want to display in the list view pane of the Layer Properties Manager.

Library Path – is the path AutoCAD that searches by default to find an xref file, including the current folder and locations set in the Options dialog box.

Limit Dimensioning is a method of dimensioning in which the upper and lower limits are given, instead of the specified dimension and

Limits - are the size of the virtual drawing area in model space.

They are largest and smallest numerical values a feature can have.

Linear Parameter creates a measurement reference between two points.

Line Conventions are standards related to line thickness, type, and purpose.

Line Spacing - is the vertical distance from the bottom of one line of text to the bottom of the next line.

Line type Scale - is the lengths of dashes and spaces in line types.

Truss - is the framework, typically consisting of rafters, posts, and struts, supporting a roof, bridge, or other structure.

Mono Truss - is a truss has only one slope as opposed two (half of a common truss).

Hip Truss - is a truss erected to sustain the angle-rafters of a hiproof.

Beam - is a long, sturdy piece of squared timber or metal spanning an opening or part of a building, usually to support the roof or floor above.

Joist - is a length of timber or steel supporting part of the structure of a building, typically arranged in parallel series to support a floor or ceiling.

Lateral Bracing refers to any piece (wood or metal) on a bridge that help keep the top chord from bending horizontally.

Schedule Bracing - is a structural member, such as a beam or prop, used to reinforced a framework, such a supporting beam in a
