Girders and beams should be assembled in cambered condition during preassembly for field conditions according to FP-14. Cambering is a technique used in the design and assembly of structural elements to counteract the deflection that occurs under load. By preassembling girders and beams with a slight upward curvature, engineers ensure that when the beams are put into service and subjected to loads, the deflection will bring them to a level position rather than allowing them to sag.

This approach enhances the overall structural integrity by anticipating and accommodating expected load conditions, leading to better performance of the structure in the long term. It is critical for the successful implementation of the design specifications and helps avoid issues related to sagging or misalignment after installation. This practice aligns with standard engineering practices and recommendations within FP-14 guidelines to ensure that the assembled girders and beams meet performance expectations under actual service loads.
