CHAPTER ONE
INTRODUCTION
Form work is the term given to either temporary or permanent mould into which concrete or similar materials are poured. In the context of concrete construction, the false work supports the shuttering moulds.
Formwork are hollow moulds, which serve as a form for concrete in this way, building components of concrete and reinforced concrete as site concrete will be constructed. In the precasf plant, mostly formwork elements come into use. The use of form work comply with the highest requirements and enable an exact, efficient and thereby economical construction of pre-cast concrete parts.
Some of the earliest examples of concrete slabs were build by Roman Engineers because concrete is quite strong in resisting compressire loads, but has relatively poor tensile or torsional strength, these early structure consisted of arches, vanlts and domes. The most notable concrete structure from this period is the panthern in Rome. To mould this structure, temporary scaffolding and formwork or false work was build in the future shape of the structure. These building techniques were not isolated to pouring concrete but were and are widely used in masonry because of the complexity and limited production capacity of the building material, concretes rise as a favored building materials did not occur until the invention of Portland cement (and developments by the edision Portland Cement Company) and Reinforced concrete.
1.2 STATEMENT OF PROBLEMS
Despite the numerous achievements of formwork in the construction of high rise buildings, a lot of problems are still associated with the design and construction of formwork for building production. These problems among others are:
Most construction companies do not see the need to the quality material for formwork hence they are discarded after use in most cases. This has constituted a lot of problems design and construction of formwork.
Use of inexperienced contractors is another problem confronting effective design and construction of various types of formwork for high rise building.
It is observed that in most construction companies, all the processes involved in formwork construction for concrete components are not duely observed by the contractors and this in most occasion causes formwork failure in high rise building.
In most cases, the owner of the project detects to the contractor the type of material to use for him or her and this has affected so many formworks design and construction negatively.

ABSRACT - [ Total Page(s): 1 ]This research project is designed to critically assess the use of formwork design and construction of high rise building. The researcher has carried out an extensive research on how important well designed and constructed formwork could be in the construction of high rise building in Nigeria. The researcher in order to achieve this aim visited libraries, handouts, journals and distributed questionnaires, personal observations. The data obtained from questionnaire was presented and analyzed using ... Continue reading---
