BIM Specialist — Cost-Optimized Full Coordination “Digital Twin” (Revit + Navisworks)

Company: Urban Perch / Nest Homes (Central Florida)Project Type: ~10 single-family homes per year (starting with one pilot ~6,000 sf)Engagement: Fixed price per home + hourly for out-of-scope revisions Objective Create a fully coordinated BIM model of our single-family homes (Architecture / Structure / MEP), run house-wide clash detection, and deliver actionable issue logs and exports we can use for preconstruction, shop-drawing checks, and estimating. We already have plans; we need coordination excellence, not just drafting. Scope & Deliverables (Standard, Cost-Optimized) Modeling (Revit, LOD 300–350 where it impacts coordination) Architecture: walls/partitions, floors/ceilings, roofs, stairs, soffits/chases, equipment closets, major openings. Structure: foundations (schematic), bearing walls, beams/headers, columns, joists/trusses (schematic depth/zones), major penetrations. MEP: Mechanical: AHUs/FAUs, returns, trunks + primary branches, key diffusers/registers in all rooms. Plumbing: stacks/vents, hot/cold trunks, fixture carriers where relevant, dryer/hood/chimney routes. Electrical: main panels, feeders, primary conduits in conflict zones; fixture placeholders on RCPs for coordination (not full lighting design/circuiting). Clash Detection (Navisworks Manage) Search sets + rulesets (hard/soft clashes; clearance zones for AHUs, panels, cleanouts). Two passes: full house clash run + one coordination re-test. Issue Register (CSV + PDF): element IDs, location, screenshots, severity, responsible trade, recommended fix. Sheets & Views Whole-house RCPs (coordination-grade, not polished for permit). Sections through corridors, stairs, mechanical rooms, over-garage rooms, kitchens, laundry, and any flagged tight zones. Saved viewpoints in NWD/NWC. Exports & Handover Revit (.rvt) with clean worksets/naming; IFC, NWC/NWD, DWG, PDFs. Quantity schedules (CSV) for major systems/elements (coordination-grade counts/lengths). 15–20 min Loom walkthrough (model organization, clash sets, key resolutions). Inputs We Provide Latest architectural, structural, and MEP PDFs + DWGs. Equipment cut sheets (AHUs, ERVs, water heaters, panels, major fixtures). Our naming/workset standard (or adopt yours—must be consistent). Target dates and a weekly coordination window. Quality Bar (How we’ll judge success) No unresolved hard clashes after re-test; soft-clash risks noted with clear fix options. Practical thresholds (e.g., ~¾" hard clash; manufacturer clearance zones). Readable, prioritized issue register (cost/schedule impact). Clean model hygiene (families, parameters, worksets, view templates). Cost Controls (Please adhere) To keep this cost-effective without losing quality: Use stock/generic families unless a clash hotspot demands custom. Reuse your templates, Dynamo QA scripts, view creation automation, and search sets. Two iterations only (clash pass + re-test) included. No option sets or alternates in the pilot. Sheet output is coordination-grade, not a permit set. If a decision would push budget, propose the leanest acceptable alternative first. Timeline Pilot: 2–3 weeks from kickoff to final handover (we’ll flex for genuine complexity). Weekly 30-min check-in during active work. Budget & Milestones Bid as a fixed fee for ~6,000 sf full coordination with two clash cycles. We prioritize efficient teams who can meet the above at a sharp price (please include your best cost-optimized number and any volume discount for 3+ homes). Milestones: 30% – Revit A/S/MEP base + initial views/search sets ready 40% – Full clash pass + Issue Register + NWD with saved viewpoints 30% – Re-test + finalized exports + Loom walkthrough Also include your hourly rate for out-of-scope revisions (design changes, added options). How to Apply (attach all three) Relevant Samples: one residential project showing your clash workflow and issue log format (screens/video OK). Process Brief (8–12 bullets): modeling standards, rulesets, QA checks, any Dynamo/automation you use to keep costs down. Pricing: fixed fee for ~6,000 sf (as scoped), hourly rate, typical turnaround, and volume discounts. Screening Questions Which LOD do you use for reliable residential coordination, and why? Your default clash thresholds for S/M/E and how you handle soft clashes/clearances? How do you ensure service access (AHUs, panels, cleanouts) is respected in the model? Share a specific coordination win (problem → your fix → cost/schedule impact). Can you provide Revit templates/view templates you’ll use to speed delivery?
