Structural Design Check Required- URGENT

I need a structural engineer to review initial designs and provide confirmation they are suitable. If not suitable, I need an alternative design/ideas.

Single Storey Side Extension in Wirral, Merseyside, UK (must comply with Building Regulations).

Foundation design- urgent must be verified within 12 hours- sooner if possible.
Calculations & design details required to confirm this (within 24-48 hours).

Steel beam design- verify existing design and provide calculations.

See attached design scope and drawings.

Please send your proposal and I will confirm & pay the deposit at 12pm tomorrow 30/06/2025 (UK time)
