PPRs are essential for stakeholders to assess the project's viability and make informed decisions.

A maintenance period in construction refers to a designated timeframe after project completion during which the contractor is responsible for addressing any defects or issues that arise in the construction work. This period typically lasts from a few months to a year, depending on the contract terms, and allows the client to ensure that the project meets the agreed-upon standards. During this time, the contractor may be required to make repairs or replacements at no additional cost to the client. The maintenance period aims to protect the client's investment and ensure the long-term durability of the construction work.

To calculate the footing size of a building, you first need to determine the load that the footing will support, including the weight of the structure and any live loads. Next, calculate the soil bearing capacity, which is the maximum load per unit area that the soil can safely support. Finally, divide the total load by the soil bearing capacity to find the required footing area, and adjust the dimensions (length and width) of the footing to achieve this area while ensuring stability and adherence to local building codes.

A construction sign is a type of signage used to inform the public about ongoing construction activities in a specific area. These signs typically communicate important information such as warnings about potential hazards, detours, and safety guidelines. They are designed to ensure the safety of both workers and the general public by providing clear and visible instructions. Construction signs can vary in size, shape, and messaging, depending on the specific requirements of the site.

Common types of stones used in construction include granite, limestone, sandstone, and marble.
