Rate analysis is a crucial step in construction projects as it helps determine the cost of materials and labour involved in the work. For brickwork, the primary components to analyze are the quantities of bricks and mortar required, as well as the labour needed for masonry work. This article will guide you through the process […]
Pouring concrete for horizontal elements such as beams and slabs is a fundamental aspect of building construction. It requires careful planning and execution to ensure structural integrity and durability. Adhering to specific procedures during concrete placement not only enhances the strength of the finished structure but also ensures a safe working environment for all involved.
Pouring concrete on a sloped surface is a task that demands skill, experience, and careful planning. Whether working on sloped concrete members, driveways, or wheelchair ramps, the use of low slump concrete is common to ensure the concrete stays in place and maintains its strength and durability. This article explains the step-by-step procedure and important
Pouring new concrete over old concrete is a common practice when repairing damaged surfaces. However, this method is only effective if the existing concrete is structurally sound. Without proper preparation and careful execution, the bond between the old and new layers can fail, resulting in premature cracking or delamination. To ensure a durable and high-quality
The connections in steel structures are essential to ensure strength, stability, and durability. Among the commonly used methods for connecting steel members are welding, riveting, and bolting. This article focuses on the preparatory steps involved in fabricating and assembling steel members connected by riveting or bolting, highlighting the critical processes of laying out, fabrication, hole
The placement of reinforcement in concrete members is a critical factor that directly impacts the structural performance and durability of reinforced concrete elements. Proper reinforcement positioning must comply with relevant codes and design specifications, ensuring that both the concrete placement and consolidation processes are carried out effectively. This article outlines practical tips and best practices
Honeycomb in concrete structures is a common defect that can compromise the strength, durability, and appearance of concrete members. Preventing honeycomb not only saves costly repairs and delays but also ensures the construction of structurally sound elements. Understanding the causes and applying proper preventive measures are essential steps for engineers, contractors, and site workers involved
A Bar Bending Schedule (BBS), also known as a schedule of bars, is a comprehensive list of reinforcement bars required for a specific reinforced concrete work item. It is presented in a clear tabular form that allows easy reference and management. The BBS includes vital details such as the diameter of the bars, shape and
Excavation in rocky ground is often essential for laying foundations of various structures. Unlike excavation in ordinary soils, rock excavation requires a distinct set of procedures, specialized tools, and skilled manpower due to the hardness and density of rocks. Understanding the right methods and safety precautions is crucial for successful and efficient excavation in such
The Profometer test is a widely used non-destructive testing technique designed to quickly and accurately detect the location, size, and concrete cover of steel reinforcements embedded within concrete structures. The test employs a small, portable instrument called a Profometer or rebar locator, which is lightweight (weighing less than two kilograms), battery-operated, and easy to handle
