I am putting together the full Bill of Quantities for a new residential building that is still in the planning stage and I need precise input from someone who can handle the numbers as confidently as the drawings. The BOQ is the priority, yet the assignment also covers cleaning up and updating the AutoCAD plans and then translating the quantified data into a clear cost estimate. Here is what I expect to land on my desk: • A structured, item-by-item BOQ in Excel (CSI or similar format) with measured quantities referenced back to the drawings. • The updated AutoCAD files (DWG) showing every take-off point and any revisions you had to make for accurate measurement. • A concise cost summary sheet tying each BOQ line to unit rates and a total project estimate, ready for fir...

I need an unpriced Bill of Quantities that covers wall works only and is produced directly in CostX. You will receive a full set of detailed design drawings; some of the wall materials are already noted, and where information is missing you may make reasonable, clearly-stated assumptions. The job is strictly limited to walls—no floors, ceilings, or ancillary items—so the take-off inside CostX should reflect that scope. I will review measurement sheets inside the native CostX file, so please keep all dimensions traceable and tag each wall type consistently. Deliverables • CostX project file with complete wall take-off • Excel or PDF export of the unpriced BOQ, structured by ANZSMM only. • Short assumption log specifying any materials or construction details ...

I need a complete structural package for a new residential building and I’m working against a tight deadline. Architectural floor plans are ready; what’s missing are the signed-off calculations and construction-ready drawings for the foundation, framing, lateral system, and roof. The site is in my local municipality, so the design must satisfy the standard building practices here—if you usually reference ASCE, ACI, Eurocode, or similar guides, that’s fine as long as the final submission can be stamped (or easily adapted) for local approval. If you have immediate availability and recent experience on residential projects, this should be a straightforward collaboration. Speed is critical—let me know how quickly you can complete the first draft and what softw...

I’m looking for a skilled pre-engineered building (PEB) designer who can take a commercial-use brief, turn it into clear AutoCAD drawings, and back every line with an accurate tonnage and material take-off. Each assignment will vary in footprint—from compact showrooms to multi-level retail hubs—so the steel weight, member sizing, and detailing must scale accordingly. Here’s how we’ll collaborate: • I’ll share the site data, functional layout, and any project-specific priorities (sometimes it’s energy efficiency, other times extra load capacity or a stronger aesthetic). • You translate that into GA drawings, connection details, and a bill of materials, then generate a concise tonnage summary that my procurement team can act on immedi...

Time is tight on a new project and I need the full AutoCAD and structural package turned around quickly. The core requirement is to prepare clean, accurate drawings in DWG that can go straight to the architect and the site team without further red-lining. Depending on how you prefer to work, the workflow may involve 2D drafting for plans and sections, 3D modelling for clash checks, blueprint sets for permitting, and the supporting structural calculations—analysis, load paths, and reinforcement notes—so let me know where you are strongest and we can prioritise the sequence. Please keep revision windows short; I need the first draft inside three days and the final package signed off no later than one week after that. Make sure your work aligns with the relevant local building co...

Hello, I am looking for a licensed New Jersey Professional Engineer to evaluate an inground vinyl pool wall collapse in South Jersey. The contractor drained all of the water out of my inground vinyl pool during work in 2025. The pool wall later collapsed, leaving the pool unusable and causing major damage. My homeowner’s insurance claim was denied, and the denial referenced poor workmanship. I am trying to determine whether fully draining the pool, improper workmanship, soil pressure, hydrostatic pressure, or failure to properly protect the pool structure contributed to the collapse. Because I am working with limited funds, I would like to start with the most cost-effective option first, such as an initial consultation, site inspection, or limited written opinion letter. If neede...

I’m building a covered outdoor seating area and want it to feel completely open, so I need a structural plan that relies on 10–11-inch steel beams and eliminates visible posts altogether. The overall aesthetic is modern and the ceiling finish will be exposed wooden planks (making maximum thickness 12 inches), so any detailing you provide should respect that clean, contemporary look. I already have the general footprint sketched, but I need you to turn it into fully engineered drawings and connection details that a local fabricator and my contractor can follow without guesswork. You’ll need to confirm span capability, size the beams, specify plates, bolts or welds, and show how the roof ties back into the house structure while staying flat on the underside for the wood pl...
