What is the OCCA project

What does OCCA mean?

OCCA stands for Off-site Contemporary Construction for Accommodation. It is a systematic solution for construction that mainly consists of three parts; OCCA Super structure for steel structures, OCCA Bathroom Pods for wet spaces and OCCA Mega Unit Facade, a system similar to the unitized facades.

OCCA Off-site system is developed by GALPAN

GALPAN (www.galpan.com) is a vertically integrated design, manufacturing and installation company for structural steel projects. Having been in business for more than 20 years, GALPAN has completed many challenging projects for a long list of international and domestic clients.


Why did GALPAN develop an off-site system?

The most significant challenge that today’s construction world faces is unmet targets concerning project delivery time and project budget control. The goal of GALPAN is to offer a solution to this widespread problem.

The off-site system components rely on the logic of “manufacturing ready-to-use products” at factory conditions in order to provide systematic solutions to construction industry in terms of time, quality, budget, and project management.

The off-site solution involves both the production and the construction aspects. The fact that GALPAN carries out design, manufacturing as well as installation activities, gives to the company all the necessary experience to be successful in the production for off-site construction.



Furthermore, steel as a building material is always processed in factory-controlled environment with high levels of manufacturing precision. The area of modular off-site construction requires high precision design and manufacturing as well. GALPAN aims to extend its experience in precision- steel manufacturing into the off-site production.

In order to perform in the most effective and professional way, GALPAN has collaborated with several distinct design and engineering companies, specialised in delivering off-site solutions.
