Why site analysis, management are important for a developer

________________

David Kireli, a civil engineer says every building project starts at a site.

“Site analysis helps to identify opportunities and constraints that influence the design outcome. For instance, understanding the movement of the sun allows for qualitative analysis of sunlight and shading on different parts of the site or building,” Kireli explains.

A thorough site analysis provides essential information that ensures a structure is not only aesthetically pleasing, but also functional, energy-efficient, and sustainable. A well-planned site allows for maximum natural lighting, ventilation, and climate control, ultimately reducing energy consumption.

House orientation

Muhammad Nsereko, a construction engineer also explains that a building’s orientation plays a critical role in its overall energy efficiency.

“A correctly orientated building can significantly reduce cooling costs by naturally maintaining a comfortable environment,” he says.

In tropical climates, optimal house orientation should minimise direct exposure to solar radiation while ensuring adequate ventilation.

To achieve this, Nsereko recommends that houses be constructed along the east-west axis, with windows facing north or south. This approach helps to reduce heat buildup and enhances natural cooling.

“For example, the living room should not face west because it will be extremely hot in the evening, a time when it is most used,” Nsereko advises.

If windows must face the east or south, he suggests adding a roofed veranda to shield against excessive sunlight, ensuring indoor spaces remain cool and comfortable.

The design plan

Mike Sengendo, another construction engineer, explains that a well-structured design plan is fundamental to a successful project.

He highlights the importance of a solid foundation, especially in areas with high water tables.

“After building the first phase of the underground foundation and allowing it to settle, a raised platform is constructed. In areas where underground water is present, the platform should be at least two to three feet above ground level to prevent water damage,” Sengendo explains.

At this stage, a high concentration of cement and 9mm by 9mm cement bricks are used since they are resistant to water penetration. Hardcore stones are also utilised, as they provide additional stability compared to standard bricks, which may deteriorate over time due to excessive moisture.

Once the platform is raised, it is filled and levelled with hardcore stones, followed by layers of gravel and sand, all compacted to enhance stability.

When laying the final concrete layer, which consists of gravel, sand, cement, and reinforcement nets, Sengendo recommends a thickness of at least five inches. This ensures a strong foundation capable of withstanding environmental stressors.The success of any construction project depends largely on the team handling it.

“The owner finances the project, consultants design the plan and oversee the work, while the contractor implements it,” Kireli explains.

Having a well-coordinated team ensures quality and timely project completion. Each member must understand their responsibilities and execute them efficiently to avoid substandard workmanship.
