SUBCOURSE OVERVIEW

This subcourse addresses the principles of designing wooden wall forms for concrete. One of the

carpenter's most important concerns is to ensure that all wooden concrete wall forms are designed for

strength and durability. In this subcourse you will be shown how to properly select the materials and

spacing of these materials to gain that desired strength. As a carpenter, you must be able to construct

these wall forms to support the concrete during placement and initial set period. This will be performed

in accordance with Field Manual (FM) 5-742.

There are no prerequisites for this subcourse.

The lessons in this subcourse reflect the doctrine which was current at the time it was prepared. In your

own work situation, always refer to the latest official publications.

Unless otherwise stated, the masculine gender of singular pronouns is used to refer to both men and

women.

TERMINAL LEARNING OBJECTIVE:

ACTION:

You will describe procedures used to design and construct wooden forms for

concrete walls.

CONDITION:

You will be given the material contained in this subcourse and an Army

Correspondence Course Program (ACCP) examination response sheet.

STANDARD:

To demonstrate competency of this task, you must achieve a minimum of 70

percent the subcourse examination.

LESSON

DESIGN FORMS FOR A CONCRETE WALL

Critical Task 051-199-4014

OVERVIEW

LESSON DESCRIPTION:

In this lesson you will learn what materials to select and the procedures necessary in designing a wooden

wall form for a concrete wall. The procedures must be performed in a step-by-step process and will be

presented in that manner in this lesson.

TERMINAL LEARNING OBJECTIVE:

ACTION

You will deign a wooden form for concrete walls.

CONDITION

You will be given subcourse booklet EN5151 and complete the review

exercise.

STANDARD:

You must complete the lesson and the practical exercise.

REFERENCES:

The material contained in this lesson was derived from FMs 5-34, 5-426, and 5-

742; and STPs 5-12B4-SM-TG; and 5-51B12-SM-TG.

INTRODUCTION

It is very important that you, as a carpenter, learn the processes involved with the designing of forms for

concrete walls. Your first step is to learn the different names of various components of wooden

concrete wallforms. This will enable you to determine what type and size of materials to use and where

to place these specific members. Your next step is to become an expert in determining the spacing of

each of these supporting members. This will enable you to design a concrete form that will successfully

handle concrete during the placing and setting up periods.

PART A: MATH REVIEW

Designing concrete forms, like other construction tasks, requires the use of a basic tool. If used

skillfully, the “tool”-mathematics-will help you to complete this task.

EN5151

Before you start the subcourse lesson, you need to perform a short review of the various types of math

problems that you will encounter throughout. If you know how to add, subtract, multiply, divide, and

are familiar with the operation symbols, you will proceed through this lesson without any difficulty. On

the other hand, if you have trouble, be patient. Examples explaining each problem are included in this

lesson. Just follow the directions, keeping in mind that you learn best by actually working out the

solutions to the problems on paper.

MATH EXERCISE

Space has been provided below each question for you to work out your solution to each problem. After

completing the questions, turn to page 1-4 and check your solutions with the review exercise answers and

feedback sheet.

1. Convert 93 feet into inches.

2. How many 8-inch stakes can you cut from a piece of lumber that is 2 inches by 4 inches by 16 feet

long?

3. How many board feet are in a piece of lumber that is 2 inches by 6 inches by 12 feet long?

4. How many 28-inch-long stakes can you cut from a 7-foot stake that is a piece of a 2 by 4?
