Board Of Directors

Mr. Bhakta Bahadur Lama

Chairman

“At A.One Builders Private Limited, our mission is simple: to build the future of Nepal through engineering excellence. My focus has always been on the ‘Plan and Act’ philosophy—ensuring that every project, whether it is a critical airport runway extension or a complex bridge network, is executed with technical precision. By investing in a high-capacity fleet of modern machinery and maintaining our own material production facilities, we ensure that we never compromise on quality or timelines. For us, construction isn’t just about moving earth and pouring concrete; it is about delivering durable infrastructure that stands as a benchmark for safety and reliability.”

Mr. Bishnu Man Lama

Director

The backbone of A.One Builders is our people and our processes. With a diverse workforce of over 240 professionals, we ensure that our internal operations run with maximum efficiency and safety. We have built a culture where QHSSE (Quality, Health, Safety, Security, and Environment) standards are integrated into every administrative decision. By managing our human resources and organizational logistics effectively, we provide our engineering teams with the stability they need to succeed. Our growth from a small firm to a multi-billion turnover company is a testament to the disciplined administrative foundation we have built together.

A.One Builders remains a partner of choice for both government and private stakeholders. I focus on navigating the competitive landscape of tenders and strategic marketing to position our company at the forefront of Nepal’s construction sector. By fostering strong relationships with external parties and identifying high-impact opportunities—from national highways to luxury residential developments—we continue to expand our footprint.
