Project & Engineering Scope Overview
Design studios win prestigious competitions at Stage 2/3, yet technical documentation bottlenecks squeeze studio margins during Stage 4/CD production. SerMimar operates as your senior technical architecture arm—producing watertight, code-checked Construction Documentation straight from federated Revit.
Engineered to RIBA Stage 4 / AIA CD precision across a reference benchmark of 2,000 – 45,000 m² under RIBA Stage 4 · AIA Construction Docs · HOAI LP 5 · ISO 128, this canonical specification unifies spatial design, multidisciplinary clash resolution, and 5D cost certainty prior to site mobilization.
Architectural Layout, Structural Grid & Spatial Zoning
Structural Grid & Modular Alignment: Fully dimensioned 1:50 setting-out plans, masonry/drywall partition types, movement joints, and acoustic/fire wall tags.
Primary column grids, facade mullion subdivisions, and subterranean parking geometry are locked onto a unified datum—eliminating non-standard off-cuts and costly site framing adjustments.
Functional Area Program & Net-to-Gross Floor Plate Optimization
Spatial Program & Net-to-Gross Efficiency: Reflected Ceiling Plans (RCP), floor finish/screed junction plans, and tiling setting-out sheets synchronized with room data sheets.
Live parametric Revit area schedules track net usable/leasable floor area against vertical cores, MEP plantrooms, and envelope wall thickness at every design iteration.
Circulation Cores, Logistics Access & Life-Safety Egress
Vertical Cores, Logistics & Life-Safety Egress: 1:20 stair, elevator core, handrail anchorage, and accessible threshold waterproofing details.
Travel distances, pressurized stair cores, ADA/accessible routing, and heavy service/loading dock swept-path geometry are validated against NFPA, EN, and local building regulations.
Site Utilities, Stormwater Drainage & Wet-Shaft Engineering
Subsurface Utilities, Drainage & Wet Shafts: 1:20 commercial kitchen, bathroom pod, terrace membrane slope, and linear drain waterproofing cross-sections.
Gravity stormwater and foul drainage stacks are modeled with true 1.5%–2.0% invert slopes, locking structural beam web penetrations and acoustic riser sleeves before rebar detailing.
Plumbing, Fire Suppression (NFPA / EN) & Hydronic Piping BIM
Domestic Plumbing, NFPA/EN Sprinkler & Hydronics: Fire compartmentation plans showing EI30/EI60/EI120 rated walls, fire-stopping collars, smoke curtains, and escape signage.
Wet/dry sprinkler grids, fire hose cabinets, booster pump skids, and hydronic manifolds are spatially coordinated above ceiling plenums without compromising architectural clear heights.
HVAC Climatic Routing, Acoustic Control & Zero-Clash MEP
HVAC Routing, Acoustics & Zero-Clash Verification: Coordinated RCPs integrating lighting coves, linear HVAC slots, sprinkler rosettes, and acoustic access panels cleanly.
Automated Navisworks and Solibri rule-sets enforce ±3 mm hard-clash tolerances and 25–50 mm insulation/maintenance clearance zones, closing 100% of BCF issues prior to tender issue.
Structural Steel / RC Framing & Seismic Performance Analysis
Structural Framing & Seismic Engineering: Slab edge step-downs, balcony thermal-break connectors, recessed matwells, and stone cladding shelf-angles coordinated with structure.
Inter-story seismic drift ratios, ductile steel moment/braced connections, foundation punching shear, and secondary facade subframes are signed off by our senior structural engineering partners.
Facade Envelope, Roof Assembly & Hygrothermal U-Value Detailing
Building Envelope & Hygrothermal Physics: 1:5 window jamb/head/sill EPDM & vapor-control details, parapet copings, basement tanking transitions, and expansion joints.
2D/3D thermal-bridge condensation risk is audited per EN ISO 6946, pairing Class A1 mineral-wool insulation, vapor-permeable membranes, and slotted seismic facade brackets at 1:5 shop detail scale.
Georeferenced Site Plan & ISO 19650 Common Data Environment (CDE)
Georeferenced Masterplan & ISO 19650 CDE: 100% live sheet generation from Revit—zero disconnected 2D drafting overrides that contradict the 3D model.
All discipline models share true survey coordinates (UTM / National Grid) and progress through ISO 19650 WIP → Shared → Published gates inside the Common Data Environment.
BIM & Construction Document Deliverables (.RVT / .IFC4 / .NWD / .DWG)
Native BIM & Construction Documentation Package: Native Revit (.RVT) with sheet sets, clean layered AutoCAD (.DWG) exports, hyperlinked vector PDF binders, and NBS/CSI Outline Specs.
Clients receive unlocked native .RVT Source + Full 1:50 / 1:20 / 1:5 .DWG & Plotted PDF Set source files, plotted PDF/DWG construction sets, and signed zero-clash audit certificates.
5D Quantity Take-Off (BoQ), Studio Fee Band & Cost Benchmarks
5D Quantity Take-Off (BoQ) & Indicative Studio Fee: The indicative engineering & BIM fee band for this reference scope is $14,500 – $29,000 (for 5,000 m² full CD package) (with indicative construction CAPEX benchmark at Tender-Ready Construction Documentation Precision). Eliminates contractor ambiguity during tender, preventing expensive design-and-build quality dilution on site.
DfMA Prefabrication, 40HC Export Packaging & Execution Pathways
DfMA Prefabrication & Export Execution Pathways: Standardizes door sets, partition types, and bathroom pod layouts across multi-unit residential and hotel schemes.
Clients may tender the open BIM package to any local contractor or leverage our integrated group factories (SerBuild steel structures, SerMimar İskele EN 12810 scaffolding, SerMimar Şömine hearths, and SerSourcing 40HC consolidation).
International Building Codes, Green Certification & Grant Readiness
International Codes, Sustainability & Compliance: Tailored to UK Approved Documents (RIBA Stage 4), German HOAI LP 5 (1:50 Werkplanung), AIA CD (Imperial/Metric), or Turkish Application Standards.
Structured directly for LEED / BREEAM / RE2020 energy modeling, UK Building Safety Act Golden Thread compliance, Eurocode National Annexes, and institutional lender due diligence.
