Engineering Hub: System Design, Drawings & BOQ
Enter the duty, or describe any requirement and attach the drawing. AutoCAD, PDF, a spreadsheet or a photograph is accepted. The desk sizes what it can from NBC 2016 Part 4, IS 15105, IS 3844, IS 13039, TAC, NFPA 13, NFPA 20, IS 732, IS 3043, IS 2189, ISHRAE and ASHRAE 62.1, draws the P&ID or single-line diagram, the scaled plan, both elevations, section A-A and the isometric, and writes the bill. A PEB shed takes length, width, eave, bay, slope, basic wind speed, crane and cladding, and draws the framing plan, the anchor bolt plan, both elevations, section A-A and a rotatable 3D model. Fire suppression and fire detection sit under Fire protection, not as a separate project type. A mark you add on the sheet is saved with the download. A licensed engineer still stamps the issue.
Choose project type
Fittings and steel is selected. The subcategories for this type are under this list. The drawing and the bill further down are the existing type page. A catalogue price is used when it matches. Otherwise a published Indian rate plus 20% is shown with its source. Erection is 10% of that system's materials, testing 2%, and transport 3%.
Subcategories
Each subcategory has its own design basis, calculation, drawings, bill and quotation.

- 2,000 m² is the area of one floor, 2 floors, 8 m height. Sprinkler heads, sprinkler branch pipe and smoke detectors are that floor counted again on every floor. The sprinkler pump stays on the remote design area.
- Prices on the quotation are ex-GST. A catalogue match is used first. Where the catalogue has no price, a published Indian rate plus 20% is used and the source is on the line. GST at 18% is added on every material line. A price the source already quoted including GST is converted to the ex-GST rate and 18% is shown separately. Erection and installation labour is 10% of that system's material subtotal, testing and commissioning 2%, and transport 3%. GST 18% is added on those allowances.

Statutory
- This is an enquiry BOQ, not a sanctioned design. A licensed consultant stamps the drawing before construction.
- The pipe rack is a structure. A structural engineer designs it to IS 800 and IS 875 and stamps the GA before fabrication.

Supply is the material and the transport. Installation is erection, testing and commissioning, and the other site services. Each section has its own ex-GST subtotal. GST and the grand total follow. A catalogue match is used when the catalogue has a price. Where it does not, the rate is a published Indian marketplace or maker price plus 20%, and the source is on the line. Every material rate is ex-GST, and GST at 18% is added on it. A published price that already included GST is converted to the ex-GST figure and 18% is shown separately. Erection and installation labour is 10% of that system's material subtotal, testing and commissioning 2%, and transport 3%, with GST at 18% on those allowances.
