FACTORS AFFECTING HORIZONTAL FORMWORK SELECTION
Selecting the formwork system for cast-in-place reinforced concrete slabs is a critical decision that can affect cost, safety, quality, and speed of construction. Many factors must be considered for the proper selection of the formwork system. Among these are:
1. Factors related to building architectural and structural design, which include slab type and building shape and size
2. Factors related to project (job) specification, and schedule, which includes the speed of construction
3. Factors related to local conditions, which include area practices, weather conditions, and site characteristics
4. Factors related to the supporting organizations, which include available capital, hoisting equipment, home-office support, and availability of local or regional yard supporting facilities
An overview of all the factors affecting the selection of formwork systems is shown in Figure 5.1. The following sections briefly define the terminology and explain how these factors affect the selection of the horizontal formwork system.
