BIM Services in New York
In New York City, much of the work ahead is on existing buildings, not new towers. Local Law 97 puts carbon limits on most large buildings, and the limits tighten from 2030. Replacing boilers with heat pumps, rerouting risers and adding rooftop plant all start with knowing exactly what’s already there. Optimar Precon provides BIM services in New York for engineers, MEP contractors and owners’ teams working on those upgrades.
- Existing buildings modeled from laser scans
- New MEP systems coordinated inside occupied buildings
- Phased models for floor-by-floor retrofit work
New York BIM Enquiry
Building size and use, the systems being replaced, and whether you have scan data.
Fixed quote within 24 working hours, depending on complexity. NDA available on request.
Thousands of Buildings, One Deadline
The city’s emissions law is turning existing buildings into retrofit projects, and each one needs an accurate model before new systems can be designed.
Boiler to heat pump
Central plant replaced with heat pumps, with new refrigerant and power routes through the building.
Riser and shaft rework
New risers threaded through shafts that rarely match the drawings on file.
Rooftop plant
New rooftop units and dunnage placed around existing structure and bulkheads.
Electrical upgrades
Larger electrical services and distribution to carry new electric heating loads.
Old Drawings Don’t Show What’s in the Walls
Many New York buildings have been altered for decades, and the drawings on file rarely match what’s in the shafts and ceilings. Designing new heat pumps, ductwork and electrical service from those drawings leads to surprises during demolition. We model the building as it really is, then coordinate the new systems against it.
As-is conditions
Shafts, mechanical rooms and roofs modeled from point clouds.
Electrification routes
New heat pump, refrigerant and power routes checked against structure.
Occupied phasing
Work split into phases so tenants stay in place.
BIM for Existing and New Buildings
Most of it in occupied buildings across the five boroughs.
Scan to BIM
Point clouds turned into Revit models of existing floors, shafts and plant.
Point cloud to BIM →MEP retrofit models
New heating, cooling and electrical systems modeled against existing conditions.
MEP BIM →Clash detection
New routes checked against structure and services that stay.
Clash detection →Roof and plant rooms
Rooftop units, cooling towers and dunnage coordinated in tight spaces.
BIM coordination →High-rise new build
Typical floors, risers and mechanical floors for new towers.
BIM modeling →Structural models
Steel and concrete frames modeled for openings and new loads.
Structural BIM →What Retrofit Teams Receive
For engineers, MEP contractors and owners’ representatives.
Existing-conditions model
The building as it stands, by floor and system.
Retrofit design model
New systems placed in the existing model.
Demolition plans
What comes out, shown floor by floor.
Clash reports
Conflicts between new and retained work.
Phasing views
Model views for each stage of occupied work.
As-built handover
Final model updated for the owner’s records.
We model from your engineers’ design. Emissions calculations, filings and stamped drawings stay with your registered design professionals.

BIM Services in New York: FAQs
Can you model an existing New York building from a laser scan?
Yes. We turn point clouds into Revit models of floors, shafts, mechanical rooms and roofs, at the level of detail your retrofit design needs. We do not carry out site scanning ourselves.
Do you calculate Local Law 97 emissions or file reports?
No. Emissions calculations and filings stay with your registered design professionals and energy consultants. We provide the models and drawings for the retrofit work.
Can you coordinate work in an occupied building?
Yes. We split models into phases by floor or zone so new systems can be installed while tenants stay in place.
Do you also work on new towers?
Yes. We model and coordinate typical floors, risers and mechanical floors for new high-rise buildings.
How is a New York BIM project priced?
As a fixed fee based on building size, systems and level of detail. Send your scope and you’ll receive a fixed quote within 24 working hours.
