Authentic surveys and soil sample testing.
Short videos from clients about their experience working with BSPEPL.
Every structure we sign off carries my personal responsibility. For more than two decades our team has followed one rule: safety first, and then the most economical solution that keeps the structure safe.
When you work with BS Projects & Engineers, you work directly with senior engineers — not just a report.
Draft MD message — please review or rewrite in your own words.
From our office at Nagerbazar, Kolkata, we work across West Bengal and have delivered projects in Bihar, Odisha, Jharkhand, Assam and Sri Lanka.
Borehole logs, laboratory test results and our engineering recommendation on the type and depth of foundation for your structure.
Yes. Our structural engineers design RCC and steel structures using the soil data from the same project, so the foundation and structure work together.
It depends on the scope — for example, the number and depth of boreholes, tests required, or the size of the structure. Send your site location and drawings on WhatsApp for a quotation.
Talk to a senior engineer before you decide. Share your site location and drawings and we will suggest the right investigation, design or test.
