Engineering Design and Calculations by KP SAG (Czechia)

Thanks to the partnership with KP SAG, in which we have a participating interest with joint decision-making influence, we can provide the necessary calculations and design activities both on the domestic and Czech market. Our experienced team of designers and engineers covers a wide range of industries, from nuclear power to chemical and petrochemical industries, power industry and water management facilities. As a result, we are a valuable partner for clients in Slovakia and Czechia who lack a responsible partner in the field of engineering calculations. These activities can be utilized within an EPC contract or independently.

Who is KP SAG?

KRÁLOVOPOLSKÁ STRESS ANALYSIS GROUP, s. r. o., was founded in 2000 by employees of the Strength Calculations Department of Královopolská RIA, a. s., formerly known as Výpočtové oddělení Královopolské strojírny Brno, a. s. Královopolská SAG thus inherited over 40 years of experience in design and calculations as a basis of its service offering. It was precisely this wealth of experience and extensive portfolio of calculations that made the partnership of our company ENSECO, a. s., and KP SAG so appealing to us, prompting us to invest our time and effort into it. We see the expansion of our services as an opportunity for professional and competitive growth, through which we aim to represent our brand in both domestic and foreign markets.


Our experienced and highly professional team of designers, calculation engineers, mechanical engineers, civil engineers, and specialists in the field of calculations for fittings, piping, vessels and steel structures address our clients’ requirements on a daily basis, from routine to specialized tasks. Services in this area of calculations can also be utilized independently by our partners, allowing them to cover the gap they need to fill for their clients within project management by outsourcing to an external company.
