INTRODUCTION

Formwork important things in completion a project impact to the cost, time, and quality of

project Formwork failures

big impact to the people involved in a project

Not occur-follow the form of design

TYPES OF FAILURES

Dimensional inaccuracy Lifting of single faced forms Propping inadequate Loss of material Surface blemishes

DIMENSIONAL INACCURACY

CAUSES

Miscommunication Error in calculation Lack of supervision Unskilled worker Material did not have proper protection

SOLUTION

The engineer should done site investigation and measure the right dimension to be used especially when steel formwork been used and need to be order from factory

Use new technology-laser

Each parties play their duties Supervisor supervise worker.

Gave proper protection to material

LOSS OF MATERIAL

LOSS OF MATERIAL

Refer to ties and props - are not correctly spaced Formwork tying

connect the two faces of the double faced forms together and affect the balance of the force between them

Formwork props Support formwork

CAUSES OF FAILURES

Inappropriate chose the type of ties Ties are not be installed or screw tightly Over tightening the ties The space between each props are not

correctly/sequence

PREVENTIONS Choose the right ties Check the accuracy on formwork installation

during the ties installation Space between the installed props to avoid

any loss material from the concrete. The engineer of the record make sure

contractor has all the design data such as live loads, superimposed dead loads, any other information which related to the

project
