The company’s 40th anniversary
Our company was founded in June 1986 – at that time as Zakład projektowania Dróg i Mostów Complex Projekt Sp. z o.o. These 40 years have been a time of challenges and joys, as well as growth. We are delighted with the journey we have undertaken, our achievements and the wealth of experience we have gained. To everyone who has accompanied us throughout this time, we would like to express our heartfelt gratitude and thanks.
Final inspections on the S19 Sokółka – Kuźnica section
After around three years of construction, the project’s acceptance procedures are drawing to a close. Over 16 km of new expressway has been built, together with a network of adjacent roads and traveller service areas, including an impressively large buffer car park designed to handle freight traffic prior to customs checks at the existing border crossing. Photos taken a few days ago can be found in the projects section.
Completion of design work for the CPK
Although the handover procedure has not yet been formally completed, we are aware that we have completed the project we have been working on for the past three years or so. It was originally intended to take less time; however, problems with the environmental permit that the client was required to provide, as well as a change in government policy, extended our work by nearly two years. This has been a period of new experiences and a reassessment of our original assumptions regarding the appropriateness of using BIM in infrastructure projects.
