Software To Create Adaptive Formwork Components
The challenge for DPR Construction’s Concrete Division was
to increase productivity by rapidly generating formwork
layout options that would automatically adapt to the varying
characteristics of buildings to be constructed. Tekla structures BIM
(Building Information Modelling) software provided the technology
to create adaptive formwork and to manage the required formwork
The manufacturing and construction industry are often compared
to each other. However, one conspicuous difference between the two is
that while the manufacturing industry mass produces the product using
one process flow, the construction industry delivers similar products in
different physical settings. Even though similar construction projects
have the same set of construction activities, unique physical settings
pose many challenges to maintaining productivity.
The Challenge and Its BIM Solution
While building the Digital arts facility at the University of California, Santa Cruz, the challenge for DPR Construction was to rapidly generate

Tekla provided the technology to create adaptive formwork components which could generate the formwork layout for different shapes and sizes of walls with varying details in different physical settings. DPR created custom components (intelligent templates) in Tekla structures that adjusted to shape and size of the wall and automatically generated a formwork layout.

Like other BIM activities using Tekla structures, formwork layout automation saved the field crew considerable time by eliminating the need to layout formwork for every wall in the building manually. The layout drawings were then given as handouts to the foreman to erect the formwork in the field. Formwork layout has traditionally been a 2D process, field situations are often overlooked, inadequately accounted for, resulting in stripping and redoing of the formwork. By generating the formwork in 3D, complex issues and project specific issues are easily identified and pre-empted at an early stage. As a result, there was no rework related to formwork erection on this project. Furthermore, the Tekla structures model helped the superintendent to manage material and pour size definition. The model was useful in identifying the panels that could be reused between pours resulting in cost savings. Formwork panels were prefabricated on site based on the Tekla structures model. Quick generation of formwork arrangement helped the team run through multiple scenarios of how to arrange the panels so that minimum material and field cuts Formwork reuse chart were required. For example, a vertical arrangement of 16’ high panel was better than a horizontal arrangement as it required fewer panels and in turn less material and labour. Savings in material and labour to construct and put into place formwork assemblies are estimated at $25,000. “Tekla Corporation is pleased to see DPR take Tekla structures into use to solve problems and add efficiency,” says Andy Dickey, Business Manager of Tekla North America’s Contractor group. “It’s interesting to see how a Tekla structure has been used in this case to increase both ‘office’ and ‘field’ efficiency. In the case of the office, formwork layout and drawings have been automated thereby creating efficiency and cost savings. In addition, they have freed time to look at more efficient ways of installing their formwork, creating increased value in the field as well. These are the real problems facing the industry and it’s great to see an innovator like DPR solving them.”
