Class Activity Discussion (15 FAQs):
- What are preliminary operations in building construction?
Preliminary operations are the activities that take place before actual construction begins. These operations ensure that the site is ready for building and include activities like site clearance, provision of access roads, and site investigation. - Why is site acquisition important before construction?
Site acquisition ensures that the legal rights to the land are secured, preventing future disputes and ensuring that the construction can proceed without legal hindrances. - What is the role of an access road in construction?
An access road allows construction materials and workers to reach the site easily, making it essential for the transportation of materials and machinery. - What does site clearance entail?
