LESSON 3
FORM DESIGN AND CONSTRUCTION
OVERVIEW
LESSON DESCRIPTION:
In this lesson you will identify the importance of form and form design and their uses in construction.
TERMINAL LEARNING OBJECTIVE:
ACTION: Identify and plan the design of forms and identify their uses in construction.
CONDITION: You are given the materials contained in this lesson.
STANDARD: Correctly answer all practice exercise questions at the end of the lesson.
REFERENCE: The material contained in this lesson was derived from the following publication: FM 5-742, with
change 1.
INTRODUCTION
Forms hold concrete until i se and produces the desired shapes and surface finishes. Forms also protect concrete
and support any reinforcing bars. Because forms represent up to one-third of a concrete structure total cost, this
lesson is very important.
PART A - FORM DESIGN
PRINCIPLES
Importance of Form Design
Formwork holds concrete until it sets and produces the desired shapes and, sometimes, surface finishes. Forms
also protect concrete, aid in curing, and support any reinforcing bars or conduit embedded within it. Because
formwork can represent up to one-third of a concrete structure's total cost, this phase of a project is very
important. The nature of the structure, availability of equipment and form materials, anticipated reuse of the
forms, and familiarity with construction methods all influence the formwork design. To design forms, you must
know the strength of the forming materials and the loads they must support. You must also consider the concrete
final shape, dimensions, and surface finish.
