Before the commencement of actual construction, a series of crucial activities known as preliminary works are carried out on a construction site. These preliminary works lay the foundation for a successful project execution. In this article, we delve into the various aspects of these preliminary works, discussing each step in detail.
Demolition involves dismantling or destroying a structure either after its serviceability period or preemptively, before it becomes unsound. The process ensures a clear path for new construction. Four essential steps define the demolition process:
Site clearance is the essential procedure to remove obstructive elements like vegetation, preparing the site for excavation. The process includes:
Surveying the site and soil is a critical step in the design and construction process. Key elements, such as soil condition, surrounding buildings, and accessibility, are defined. Soil survey is imperative for stability and integrity, considering factors like soil strength and potential changes in subsoil conditions.
Planning involves selecting the best method and order of work for a project. It addresses “What to do” and “How to do it.” The significance of planning includes:
Detailed designing provides a precise physical description of the structure, including stability, strength, and rigidity. It serves as the basis for construction, providing drawings and reports for accurate cost estimates and scheduling.
Cost estimation involves forecasting probable costs for fulfilling project objectives. It includes direct costs, contingencies, supervision charges, and miscellaneous expenses.
Once these preliminary works are completed, the actual construction process begins. These preparatory steps are integral to the successful execution and completion of any construction project. They lay the groundwork for efficient planning, resource allocation, and cost-effective construction.
