Structural steel detailing can shorten the timeline for a project. It does this by reducing design conflicts before fabrication. This ensures that shop drawings are ready for fabrication and change orders are decreased. It also maintains erection sequencing and standardizes documentation per AISC codes. These factors detect and reduce potential delays before causing any costly on-site hurdles.
What Is Structural Steel Detailing?
It is a process in which the engineered design of a structure is transformed into shop and erection drawings. These drawings specify all fabricated components. The purpose of this detailing is to explain all fabrication needs for building components to manufacturers and erectors.
How Does Clash Detection Save Time?
Steel structure detailing now uses 3D BIM tools. It allows detailers to identify clashes between mechanical, electrical, and architectural components with structural elements before fabrication begins. This is also known as virtual clash detection.
It takes days or weeks to fix the drawings and resolve clashes detected onsite. This detection removes project delays. However, if clashes are detected during detailing, it takes only a few hours. Therefore, structural detailing services often integrate clash detection during detailing, not onsite.
How Does Accurate Detailing Reduce Rework?
Rework is expensive because it repeats labor that was already paid for once. A detailing error that reaches the fabrication floor often means:
Re-cutting steel
Re-ordering material
Re-sequencing a delivery schedule
There are the following stages at which errors can be detected and respective corrections can be made:
Design phase: Errors are corrected on a screen at near-zero cost.
Fabrication phase: Errors require re-cutting steel and reissuing shop tickets.
Erection phase: Errors cause crews to stop work at a construction site, possibly leading to contractually stipulated penalties for delays.
Thus, the critical way in which to protect the project timelines is managing problems at the earliest possible stages.
Why Do Fewer RFIs Accelerate Construction?
RFIs (Requests for Information) are an important source of missed schedules on steel construction projects. RFIs occur when information in the contract documents is unclear or missing. It requires the requesting party to clarify directions. Fewer RFIs speed up construction schedules because RFIs that occur during the fabrication stage add days or weeks to a project timeline. This happens because the steel detailing company has to revise the shop drawing. Shop drawings that provide information related to the code requirements will reduce RFIs since fabrication issues are addressed in advance.
How Can Errors Accelerate Construction Costs And Why Should They Be Avoided?
Errors in fabrication in shop drawings result in increased construction costs. The construction cost is increased because there may be extra labor for rework. On-site errors also lead to increased costs because operations may have to be stopped for corrections. The most effective method to prevent errors and speed up a project timeline is early detection and correction. This can be achieved by detecting errors during the detailing process. At this stage, errors are fixed by making small changes in BIM models or shop drawings.
Conclusion
Projects seldom face delays on construction sites because many inefficiencies in scheduling, material procurement, and even labor planning occur before the project begins. Steel construction projects experience delays caused by clashes between MEP systems and structural elements. These delays can be easily detected with BIM modeling. The use of shop drawings to communicate design needs ensures clarity in expectations between engineers and erectors. This leads to accelerated timelines by minimizing RFIs, reworks, and material delivery delays. SMA Estimating LLC offers structural steel detailing services that utilize these techniques to help projects stick to their timelines and budgets.
