I need a meticulous quantity survey and cost estimate that I can hand straight to our fabricators and, ultimately, to the client as a firm quotation. Your task is to extract every length, fitting, transition and accessory from the plans, calculate sheet-metal areas and weights, apply labour factors, and produce a clear pricing workbook. I expect the file in Excel (or a comparable format) with sections for raw material, fabrication hours, installation hours, consumables and mark-ups so I can adjust numbers if needed before submitting the quote. Accuracy is critical; the totals must reconcile with the drawings and the gauge specified. If you normally use tools like AutoCAD, Revi...

I already have a set of layout drawings that mark out where the eleven axial fans should sit across the 37 m × 27 m footprint of Basement 1 and Basement 2. What I need now is your help turning those mark-ups into a fully detailed, code-compliant smoke–extraction package. The core of the assignment is straightforward: confirm the proposed fan positions, size the very small amount of ductwork those fans will connect to, and show all dimensions, offsets and clearances so the installer can fabricate and fix without coming back with questions. Because the space is tight, I prefer the duct dimensions to stay flexible—use whatever cross-section best fits each run once you have checked airflow and velocity, as long as you remain within standard sheet-metal sizes. You will recei...

I’m seeking a Los Angeles–licensed designer who can deliver a full set of permit-ready documents for a new 700 m² single-family residence. The very first milestone is to produce coordinated architectural, structural, HVAC, and complete water-and-electricity (MEP) drawings; later phases will follow as the build progresses, so I’m interested in a partner who can stay involved for several years. Scope of the initial package • Architectural and structural sheets stamped for LA jurisdiction • HVAC layout sized for local energy code compliance • Water supply, drainage, and fire-protection schematics • Electrical and low-voltage plans, panel schedules, and load calculations • Revision cycles until city approval What to include in your prop...
I will soon issue a full drawing package—over 10,000 m²—for a new development in the Republic of Congo and need every sheet professionally proof-read before it goes to the authorities and contractors. Of course, if you are a full-case designer or Agency who can undertake the construction drawings of building structures, HVAC, and electricity, you can also contact me directly. At present, the project is still in the concept design stage, and we will start drawing construction drawings soon. If you are interested, please send me your quote structure. What needs checking • Architectural, structural, HVAC, plumbing/water and electrical construction drawings. Key tasks • Spot and correct dimension errors, note inconsistencies, missing call-outs and c...
