steel_gauge_thickness | Look up sheet steel gauge thickness (gauges 3-28) in inches and mm with lb/ft², for plain, galvanized or stainless series. Published nominal values for estimating and orientation, not design guidance. params: gauge*, material |
steel_plate_weight | Compute carbon steel plate weight from thickness (decimal or fraction) and width/length in inches, with optional material cost via price_per_lb. Published nominal values for estimating and orientation, not design guidance. params: thickness_in*, width_in*, length_in*, price_per_lb |
steel_shape_weight | Look up an AISC shape designation (W, C, MC, L, HSS, PIPE) for lb/ft, depth and area, with optional piece weight. 14th-Edition-era data. Published nominal values for estimating and orientation, not design guidance. params: designation*, length_ft, qty |
steel_connection_reference | Describe a structural steel connection type (behaviour, use, what goes wrong) by name, alias or slug — or look up a structural bolt grade (A325, A490, A307). Published nominal values for estimating and orientation, not design guidance. params: name_or_slug* |
steel_bolt_pretension | RCSC minimum pretension for A325/A490 structural bolts by diameter, with the turn-of-the-nut rotation when a bolt length is given. Published nominal values for estimating and orientation, not design guidance. params: dia*, length_in |
steel_pipe_schedule | Steel pipe dimensions by NPS and schedule: OD, wall, inside diameter and lb/ft for schedules 5, 10, 40/STD, 80/XS, 160 and XXS. Omit the schedule to list them all. Published nominal values for estimating and orientation, not design guidance. params: nps*, schedule |
steel_section_weight | Weight of round bar, square bar, flat bar or round tube from dimensions in inches — lb/ft and optional piece weight, in carbon, stainless or aluminum. For AISC designations use steel_shape_weight; for plate use steel_plate_weight. Published nominal values for estimating and orientation, not design guidance. params: section*, dim1_in*, dim2_in, length_ft, material |
steel_mtr_check | Screen a mill cert's yield and tensile against the specified limits for A992, A572 Gr. 50 or A36 — a screening aid, not acceptance. Published nominal values for estimating and orientation, not design guidance. params: grade*, yield_ksi*, tensile_ksi* |
steel_takeoff_weight | Roll a member list (AISC designation, length in feet, piece count — up to 500 lines) into a bill-of-steel ledger: weight per line, total pounds and tons, piece and lineal-foot counts. Net weight only; unmatched designations are listed, not guessed. Published nominal values for estimating and orientation, not design guidance. params: members* |
steel_coating_area | Surface area to coat for an AISC shape: ft² per foot from the cross-section perimeter, piece/lot area with length and qty, optional interior faces for galvanized tubes and gallons at a supplied coverage rate. Published nominal values for estimating and orientation, not design guidance. params: designation*, length_ft, qty, include_inside_faces, coverage_sqft_per_gal |
steel_rfq_generate | Generate a vendor-ready Request for Quotation (.xlsx) from structured takeoff line items — grouped by material, with vendor pricing columns, totals and standard terms. You pass parsed line items and a company name; returns a download link that expires within ~48 hours. Nothing you submit is stored. params: company_name*, company_location, project_name*, project_location, date_issued, line_items*, nesting_rows, terms |
steel_pdf_markup | Add real Bluebeam-compatible annotation objects to a drawing PDF — counts, length/area measurements with live scales, RFI clouds, callouts — from a markups JSON you supply plus placement coordinates. Pass the PDF as an https URL or small base64; returns a marked PDF download link that expires within ~48 hours. Markups appear in Bluebeam Revu's Markups List. You decide placement; the tool guarantee params: pdf_url, pdf_base64, markups*, scale, page_scales, coordinate_space, author |
steel_rfi_generate | Generate a formal Request for Information PDF from structured fields — header, meta grid, subject, description, proposed solution, attachments, and a blank response block for the design team. You do the judgement (one issue per RFI, exact drawing references, a proposed path forward); the tool guarantees the format. Returns a download link that expires within ~48 hours. Nothing you submit is stored params: company_name*, company_location, rfi_number*, date*, project_name*, project_number, submitted_to*, submitted_by*, reason, drawing_refs, spec_refs, subject*, description*, proposed_solution, response_needed_by, attachments |
steel_ncr_generate | Generate a formal Nonconformance Report PDF: identification, description, the violated requirement, containment, root cause (prose or 5-Whys chain), disposition (accept-as-is/repair/rework/reject) with actions, and blank quality-review and sign-off blocks. Flags accept-as-is dispositions whose corrective action describes physical work. The disposition decision belongs to the responsible quality au params: company_name*, company_location, ncr_number*, date*, project_name*, project_number, raised_by*, trade_or_supplier, location, description*, requirement_violated*, containment, root_cause, root_cause_whys, resolution*, resolution_justification, corrective_action, preventive_action |
Entries describe changes in tool definitions. They are not statements about a server, its quality or its author. The grade measures how the tool definitions fit model providers (token cost, schema compatibility, confusable names) as scored by the ToolFit engine at the time of the listing. JSON: append .json.
