    Structural report

    Posted 01 March

    I instructed SG to do a structural report for internal alterations. I was done professionally, on time, and took into account some revisions of the plan that I had in the process. Thank you the work!

    Review of SG Structural Engineering / Sandhya Mahadevan

    Posted 04 February

    ​Sandhya Mahadevan carried out the structural engineering work at our property in north London. She was attentive, listening carefully to our requirements, produced designs speedily to our specification and saw the project through to completion, coordinating effectively with the contractor and steering it through planning controls at Haringey council. She always made herself available, responded to queries, even late into the evening, and acted promptly and decisively to revise plans where necessary. I would wholeheartedly recommend her for similar engineering projects.

    Prompt, transparent feedback

    Posted 01 February

    Sandhya was prompt in his response, he was detailed and transparent. After a few text messages, he said my proposal to remove a chimney breast was not going to work easily and advise me to ponder it against other options. Very grateful for the honesty, which saved me time and probably money.

    Excellent job

    Posted 28 January

    We had an excellent experience working with Sandhya. She was professional, knowledgeable, and incredibly thorough from start to finish. Everything was explained clearly, and she took the time to answer all our questions with patience and confidence. The work was completed on schedule and gave us total peace of mind. Highly recommend her to anyone looking for reliable, top-quality structural engineering services.
