TANGObuilder is applying aerospace structural analysis to reduce costly errors in structural design for building construction. The technology also saves time by eliminating much of the trial and error in the design process that leads to excessive use of materials.



One of the major bottlenecks in construction a new building is the structural design creation. It is largely a manual process that is prone to error; the consequences of such errors range from project cost overrun to construction worker injury.

However, two entrepreneurs discovered it was possible to apply advanced aerospace analysis techniques to automate the construction industry’s structural design process. Martin Diz and Juan Aleman created TANGObuilder to address a canonical problem in structural design. TANGObuilder uses robust aerospace structural analysis techniques to optimize and automate structural building designs. The startup is based in San Francisco.

Ralph Gootee, cofounder of PlanGrid (acquired by Autodesk for $875M) and an angel investor in TANGObuilder, says, “The software used in the building design process has seen no significant update in the last 20 years. TANGObuilder brings aerospace’s design methodologies and advanced algorithms into the construction industry, drastically reducing time and cost for new building development.

Martin Diz: The main problem is finding an initial design solution that is safe and meets the architectural intent, budget, and time constraints of the building owner or real-estate developer. Current engineer tools intend to verify structural designs. If the engineer can not propose an optimal design solution, then the design will be suboptimal.

The design process is tedious and cumbersome since it is a trial and error search for a valid structure. It requires weeks of coordination and back and forth with all stakeholders. Structural Engineers propose a solution and then check if it is valid; if it is not valid, the engineer has to propose a new solution. If the structure is valid, they need to try an alternate structure to see if there is any possible optimization.
