Porch Steps Permit Engineering Drawing

I need a set of stamped engineering drawings for a small project: replacing seven existing wooden porch steps with concrete steps finished with bluestone pavers. The steps will sit atop two new cinder-block cheek walls. Washington, DC permit reviewers seem focused on the foundation, so the drawing must make that aspect crystal clear. Here’s what I can give you right away: current photos, porch measurements, and a rough sketch showing the proposed layout. You’ll also have direct access to my contractor for any field dimensions or construction details you need. Your plan must address: • Foundation design that meets DC code (depth, width, frost line) • Concrete and bluestone material specifications, including reinforcement, mix strength, and paver thickness • Structural support for the cheek walls and the stair slab, showing rebar, connections, and bearing points I’ll handle all conversations with the permit office myself, but I may ask you to clarify a detail if they raise a technical question. Turnaround is important—we’d like to submit within the next week if possible. Deliverable: a sealed PDF drawing set (plan, section, and details) suitable for immediate permit submission in Washington, DC.
