My goal is to take several upcoming Mechanical, Electrical and Plumbing scopes from the first sketch straight through commissioning and hand-over. I therefore need seasoned, end-to-end guidance that covers every decision point—concept design, detailed calculations, drawings, equipment selection, code compliance, procurement, installation sequencing, testing, and final close-out. The assignment spans all three disciplines, so I will rely on you to align ductwork, power distribution and piping layouts into one fully coordinated package, flag clashes early, and help optimise energy, water and maintenance costs. Because this is an A-to-Z brief, I expect practical advice on site logistics, contractor coordination, scheduling and quality checks in addition to the core engineering work. T...

I have a set of mechanical-ventilation drawings that call for rectangular ductwork in 20-gauge galvanized steel. 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...
