Design and Consulting

Optimal support in the structural design process.

Engineering design solutions

Design structure for construction projects is a complex process that consists of several stages. It requires a team of architects, structural designers, MEP engineers,  technology engineers, project managers and others with a wide range of engineering expertise. The successful design of a building is accomplished when the aim is to create structures that, at the same time, would meet aesthetic and energy efficiency demands, are comfortable and safe to be in. The decisions that engineers make during the project’s design will affect everything from the project cost and duration to the ultimate safety and viability of the structure; therefore, our principal is to optimise and automate design processes using a revolutionary parametric/algorithmic 3D modelling method. With software such as Rhino3D, STRAKON, Diamonds or Oasys we can do it professionally. By applying the most appropriate software and rational solutions, we aim to carry out the BIM environment projects efficiently.

„Dirbu treji metai su NJ Optimal produktais, tai kokybiškos, rinkoje mažiau žinomos, tačiau ne prastesnės programos. Esu patenkintas NJ Optimal teikiamais produktais, jie leidžia turėti ir projektuoti pastatus su stipriais įrankiais.”

Frequently asked questions

NJ Optimal has a lot of experienced engineers in different design branches. We would be more than happy to share this experience. Knowing and having many different software solutions helps us to create successful projects from A to Z.

It depends on project and our busyness. We are always trying to answer about terms as fast as possible.

Only if you need live consultations. Commonly we are working from our office and reach you out using MS Teams.

First of all we need informative task description, in this case we can calculate and plan more precisely. Then we are having a meeting where we talk about terms and conditions, sign agreements and start working.
