Design and Estimate Models
High Concrete Preconstruction Modeling Process
There are two phases of preconstruction modeling for a sales project at High Concrete. Each has a specific role in the sales process. One is more on a design approach while the other is based on pricing. Not all projects will go through the design portion of the modeling process. This phase is utilized more in the design-assist category when we are involved in the project early on and can help streamline and make a design precast friendly.
Assistance with customer design, panelization, layout, logistics, and direct customer guidance along with a sales representative.
In the estimation phase, we determine budget materials, difficulty, and transition the design into engineering drawings.
The main difference between preconstruction and estimator models is the preconstruction model could have more architectural glamour to it. The other difference is the preconstruction designers have spent much more time on the model to develop a design from scratch.
Benefits of Preconstruction Design Models
Preconstruction designers produce models to help owners and architects develop the design of their building into a precast efficient structure. This promotes the use of HCG standard products providing an additional cost advantage.
This phase of modeling is not utilized on every project but is requested in addition to an estimate by the sales team for design-assist projects. The preconstruction designer would take the information provided by the customer and produce them into a 2D/3D model. Appropriately calling out precast elements and logistics.
As a result, this phase allows architects and owners to be able to see their project as a precast building, reduce lead times, and also highlights adjustments needed to be able to make that happen.
In general, every hard priced estimate that goes to market will have a 3D model associated with it to serve as the basis for the cost estimate. This is amassing model that shows geometry and piece details only and is very similar to preconstruction designer models. The estimators typically have contract drawings that specify the design which is referenced in order to build the model for cost.
Pricing out the project begins with our estimating modelers. This team looks at the project from an engineering point of view to help determine all elements needed to produce a precast project.
By building models, accurate and detailed piece takeoffs are generated. The model and takeoff serve as the basis for determining all material needed, labor required, and sequencing to determine an overall project cost and schedule. Using a semi-automated process, allows our team to continue to elaborate on the 3D model, but also generate an accurate cost associated with each element.
If a preconstruction design model is not created prior, they will also need to assure that the project is precast friendly and potentially work with the architect to get it to the point that it is efficient.
All estimators at HCG are trained in Tekla and are utilizing it to build models for estimating project costs. These models are also used for advanced project planning and scheduling.
