Understanding the Initial Stages in Construction Projects

Before the actual construction work kicks off, several essential activities take place on a construction site. These activities, collectively known as preliminary works, play a crucial role in ensuring the smooth progression of a project. In this article, we will delve into each of these preliminary works, breaking down the processes involved.


Demolition: Disassembling Structures

Demolition marks the initial phase, involving the dismantling or destruction of a structure either after its service life or before it becomes unserviceable. This process, follows a meticulous four-step approach:

  • Surveying of buildings for demolition
  • Removal of hazardous materials
  • Method of demolition
  • Implementation of safety measures

Site Clearance: Making Way for Construction

Site clearance is a critical step to remove obstacles like vegetation, preparing the site for excavation.

  • Grubbing of bushes or trees
  • Removal of topsoil to establish reduced levels

Site and Soil Survey: Foundation Insights

Surveying the site and soil lays the foundation for the project, providing insights into soil conditions, surrounding structures, and accessibility.The significance of these surveys in determining:

  • Site suitability
  • Economic foundation design
  • Changes in subsoil conditions

Planning: Structuring the Project

Planning involves selecting the best method and sequence of work for the project. It answers the questions of ‘What to do’ and ‘How to do it.’ The importance of planning lies in:

  • Minimizing costs through optimal resource utilization
  • Reducing irrational approaches and conflicts
  • Encouraging innovation among construction managers
  • Enhancing competitive strength

Detailed Designing: Blueprint for Construction

Detailed designing provides a comprehensive description of the structure, covering blueprints and structural aspects.The importance of detailed design in assessing stability, strength, and rigidity. The design offers:

  • Drawings and reports for accurate construction estimates
  • Consideration of construction, operating costs, and scheduling

Cost Estimation: Forecasting Project Expenses

Cost estimation forecasts the probable cost for project fulfillment, covering various items of work and stipulated schedules. The detailed cost estimation includes:

  • Direct cost of various work items
  • Contingency provisions
  • Direct supervision charges
  • Miscellaneous expenses like water supply, sanitation, and electric supply
  • Labor accommodations, field offices, etc.

In summary, these preliminary works set the stage for a well-organized and cost-effective construction project, ensuring that every step is thoughtfully planned and executed.
