The document discusses the requirements of good formwork for construction projects. There should be 8 key requirements: 1) Easy removal so it does not damage the concrete surface, 2) Economy by reducing costs through proper design, 3) Strength to withstand loads from concrete, compaction, and curing, 4) Rigidity with minimal deflection of no more than 1/300 of the span for visible surfaces and 1/150 for hidden surfaces, 5) Minimal leakage through tight joints between sections, 6) Smooth surface for easy stripping and a quality finish, 7) Light weight for ease of handling, and 8) Use of quality materials to support the concrete pour and curing process. Proper design and construction are important to meet all

2. REQUIREMENTS OF
GOOD FORMWORK

3. A good formwork should satisfy the
following requirements
1. Easy removal
2. Economy
3. Strength
4. Rigidity
5. Less leakage
6. smooth surface
7. Light weight
8. Quality
9. supports

4. 1. Easy removal
The design of formwork should be
such that it can be removed easily with
least amount of hammering.
The removal of formwork should
cause least injury to the surface or
edges of the concrete.

5. 2. Economy
As the formwork does not contribute
anything to the stability of the
finished structure, it should
therefore, be made economical by
reducing the cost through proper
design and construction.

6. 3. Strength
The formwork should be strong
enough to withstand all loads coming
on it, such as dead load of
concrete. and live load during its
pouring. compaction and curing.

7. The loads on formwork should be
estimated carefully. The over-estimation
of loads result in expensive formwork
and the under estimation of loads
results in the failure of formwork.

8. 4. Rigidity
The formwork should rigid (stiff)
enough so that deflection is minimum.
for visible surface in completed the
work. the deflection limited to 1/300
of span and for hidden surface. It is
limited 1/150 of span. It should be
noted that a rigid formwork will be
robust and stiff enough to allow
repeated use.

9. 5. Less leakage
The formwork should be so arranged
that there is minimum of leakage
through the joints. This is achieved
providing tight joints between
adjacent sections of the formwork.

10. 6. smooth surface
The surface of the formwork should
be smooth, and it should afford easy
stripping This is achieved by applying
crude oil or soft soap solution to the
inside surface of formwork.
