Structural Systems Selection

When it comes to delivering value one of the areas Ceco can help you the most is structural systems selection. Selecting the right structural system is critical to your project’s success. With more than 100 years of experience building virtually every kind of concrete structure imaginable Ceco has the extensive project experience and expertise to help your project team analyze structural systems for the best possible outcome based on your goals. Concrete isn’t always the right choice among available structural systems and we’re not in the business of telling you otherwise. Ceco has kept the doors open since 1912 by giving our clients the information they need to succeed on their project – whether we remain involved or not.

We strive to be a resource for our clients providing free input on approach, formwork systems selection, shoring system selection, and structural systems selection. There are a number of viable concrete structural systems to consider when looking at concrete vs steel. All concrete structural systems share the benefits provided by concrete as a material but each has nuances that can help you achieve the specific project goals you wish to.

We will always suggest the project team use a Choosing By Advantages (CBA) format to identify the best structural system for your project. Every project deserves a thorough analysis including the ancillary items affected by each different structural system such as the reduction in energy, skin and fireproofing costs experienced with a concrete structural system.

Concrete isn’t always the right choice of structural systems but when it is it can significantly reduce initial costs and provide the owner a high quality, high performance structure that will last many years with little maintenance. Contact us today to see if a concrete structural system is right for your project.
