Skills Assessment:

Skills in Architectural Job Requirements Not Much A little A lot

I know how to draft foundation plans.

I can draft structural floors and roof framing plans.

Activity 1

A. Directions: Read each item carefully. Identify the correct answer. __________ 1.The process of establishing the perimeters of a house.__________ 2. They are wooden sticks or post driven to the ground.__________ 3. They are wood stick nailed horizontally to the stake.__________ 4 It provides ultimate support of the structure.__________ 5.It is the most suitable way of determining the soil condition.

B. Directions: Enumerate the following and write the answer on a separate sheet of paper.1. Give the Five (5) materials and tools used in laying out?

2. Give the Four (4) causes of foundation movement?

Activity 2Directions:1. Read and answer honestly in a separate sheet of paper the questions below. You can visit a site (construction) and see for yourself the importance of foundation in building high rise structures and residential

houses. 2. For the whole class: 2.1 Let the students group themselves into 3-5 depending upon the number of students in the class.2.2 Let them discuss among themselves the importance of having a solid foundation for a building or a residential unit.2.3 Let the group leaders report their reasons and answers to the class.

Questions to Ponder:1. Why is soil testing an important aspect to consider in the design and construction of a building?2. How does having a good and suitable foundation affect the building design and its strength?3. Why is having out the corners and squaring it important prior to construction?

Note: Rate yourself honestly using the assessment tool prepared for you below.

How did you find the given activity? Which among the elements in designing foundation matters to you most? Well, you are just starting, move forward to enrich your understanding. Enjoy reading. Have fun!

Activity 3Directions: Read each item carefully. Identify the correct answer.__________ 1. A footing which supports a wall.__________ 2. The part of the building below the surface of the ground.__________ 3. A footing which supports a single column.__________ 4. A kind of foundation wherein concrete is poured directly to the ground with footings placed where extra support is needed.__________ 5. A wall that supports or carries a load.

B. Directions: Enumerate the following:1. What are the two (2) types of walls?

2. Give the three (3) kinds of loads?

3. Enumerate the seven (7) classes of footings according to load.

4. What are the six (6) types of foundations?

Activity 4

Draft Foundation PlanFollow the given Procedures:1. Locate position of wall footings, columns and column footings on the Floor Plan.2. Indicate sizes of columns and footings to be used based on accepted

architectural and structural requirements ( in this case we may simply assume).3. Indicate width of wall footings and thickness of wall (4” THK CHB and 0.40) width of footing.4. Draw outlines of footings and columns based on accepted architectural drawing practices.5. Finalize the drawing by completing the specifications for the detail drawing of footings and columns.

Activity 5

Drafting Detail of Columns and FootingsProcedures:1. From the foundation plan drawn in the preceding operation, determine the types of columns used. (for every type, a detail drawing must be drawn)2. Determine the sizes of footings and columns used in the foundation plan.3. Layout the plan of the foundation with the corresponding sizes used.4. Layout the column section following the measurement used.5. Draw the reinforcing bars and label.

Note: Your output will be evaluated according to the following criteria below. The teacher will assigned the percentage rating accordingly:

1. Accuracy of:a. lines used according to standardsb. scaled measurementsc. notations and specifications

2. Work Values:a. work attitude/behaviorb. safe work habitsc. housekeeping and maintenanced. time management

How did you find the given activities? Are they challenging?Now, after knowing all the theories, concepts and practices in drafting structural layout and details, you are going to assess yourself how far your understanding about the topic is. Perform the activity below to measure if you already acquired the needed skills by performing the given assessment. Good luck!!

Activity 6. Summative Assessment: Lesson 1

You are now going to prove yourself how much learning you had acquired.This is also to test your skills in precise measurements and proper notations…Go!

Directions: Draft the following. Use appropriate drawing tools and materials.A. Foundation PlanB. Detail of Columns and Footings
