Your Global Solution for BIM Excellence.
Combining our commitment for quality and value, we have emerged as a trusted BIM manager partner for UK design, construction, and property industries.
Our journey began in 2021, when a small team of architects and BIM managers set out to transform the outsourcing landscape with a people-centric approach. Today, we are a growing team of 15+ skilled professionals, with offices in the UK and Sri Lanka. Sri Lanka, a rising global knowledge hub, sharing strong ties with the UK and striving to become a knowledge-based economy.
Drawing from our collective knowledge and skillsets, we merge the expertise gathered from design practices, contractors and property developers in London, nationally and internationally with the exceptional skills of our BIM manager professionals in Colombo, Sri Lanka
From large-scale mixed-use developments in the UK to prefabricated single-family homes in Sri Lanka, our track record demonstrates successful delivery of diverse projects applying BIM protocols. Whatever your requirements may be, we are fully equipped to meet them.
