Title: Project No.20631 - Caf Upper Floor System Flexing Issue Introduction: During a recent Quality Assurance and Progress Inspection, an issue was noted with the upper floor system of the caf in Project No. 20631. The carpenter reported excessive flexing in the floor system, even before the addition of walls and other structural loads. Problem Identification: Upon reviewing the building plans and the manufacturer's specifications, it was discovered that the problem lies with the HJ400 I-beam joists used. The maximum span width for an HJ400, given a roof load width of 3600mm, is only 3550mm. However, the span in the current setup is 13000mm, far exceeding the limit. This discrepancy explains the flexing that's been observed. Notably, HJ460 beams, as referenced in the conflicting plan, do not exist. Recommended Solution: To correct this issue, the existing HJ400 I-beam joists should be replaced with SMART LVL15 joists. These have a greater load capacity and will meet the span requirement of 13000mm. Additional reinforcement should be provided under the parallel wall through the installation of double Smart Lvl joists. Implementation Process: Communication: Notify all relevant stakeholders, including the project team, client, and any sub-contractors, about the issue and the planned solution. This communication should be done in accordance with BAA Constructions' policies and procedures. Planning and Coordination: Arrange a meeting with the carpentry team to discuss the replacement process and timeline. Ensure that other aspects of the project are scheduled around this work to minimize disruption. Procurement: Order the required SMART LVL15 joists and organize for their delivery to the site. Execution: Have the carpentry team remove the existing HJ400 joists and replace them with the SMART LVL15 joists. Install double Smart Lvl joists under the parallel wall. Quality Assurance: Once the replacement is complete, carry out another inspection to confirm that the flexing issue has been resolved and the construction complies with the NCC/BCA. 13 Documentation: Update all project documentation to reflect the changes made. This includes revised building plans and records of the inspection and remedial work done. Professionals Involved: This task will primarily involve the project manager (for planning, coordination, and communication), the procurement team (for ordering and delivering the joists), and the carpentry team (for executing the work). Other professionals, such as a structural engineer, may need to be consulted to ensure the solution complies with relevant building codes and standards. A quality assurance team should also be involved in the post-repair inspection
