Schedule Savings and Schedule Certainty – Advanced Project Delivery allows for open communication between the design and construction teams, enabling the project steel to be procured, fabricated and erected on time with minimal change order and schedule impact. For many fast-track projects, the traditional delivery schedule with the fabricator designing the connections and starting the detailing is not possible given the Owner’s schedule.
Cost Certainty – Advanced Project Delivery allows for progress Tekla models to be issued with the bid documents. These models, although provided only for reference, contain detailed examples of some of the more complex connections in 3D. Providing more information earlier in the bidding process helps provide a greater understanding of the project and reduces estimating uncertainty. Combined with a tonnage schedule provided with the bid documents, all fabricators are on a level playing field with respect to the project’s scope and complexity, leading to low percentage spread between high and low steel bids.
Increased Trade Coordination – Modeling structural steel members accurately early in the process enables early trade coordination. Modeling the concrete envelope, concrete reinforcing and structural steel in Tekla simultaneously allows for the detection and elimination of clashes between steel and concrete reinforcing between trades. Additionally, the Tekla model can be imported into programs such as Navisworks to perform clash detection for other trades such as exterior façade and interior MEP routing throughout the construction process.
Reduction in RFIs – Collaborating with the design team during production of the model allows for a seamless, real time flow to resolve engineering issues as they are discovered. Most of this work occurs prior to a steel fabricator even getting involved in the project or in a particular area. With weekly coordination meetings throughout the development of the design and model, formal Request for Information (RFIs) are dramatically reduced resulting in less Owner-Architect-Contractor processing time and additional schedule benefits.
Reduced or Validation of Change Orders – Preparing and utilizing a Tekla model throughout the design and construction process, enables quantities and complexity to be identified early on as the design progresses. Changes, once a model or drawings are issued, can be tracked and compared as well as quantities verified. Since all information is shared, utilizing a collaborative design/construction approach, potential change orders are identified earlier in the process and discussions on the necessity of the change is evaluated prior to implementing, thus leading to cost control and reduced change orders.
