Voyansi what we build
What an AEC software development company actually does.
Architects, engineers, and contractors have the design tools. The gap is everything around them: integrations, automations, viewers, and data flow between systems that were never meant to talk. That is the work.
Revit plugins and CAD extensions
Extensions that pick up where the native toolset stops. Built by engineers who have shipped them before.
Field-to-office data pipelines
BIM data flowing from the model into BI, ERPs, and field tools. No manual exports, no spreadsheets in the middle.
Custom 2D and 3D web viewers
Three.js and WebGL viewers tailored to the workflow: overlays, custom properties, scan ingestion, status colorization.
who we work with
Built for AEC, MEP, and Real Estate.
Our AEC software developers carry domain context into the first conversation. That changes how fast the team gets to a working system.
AEC
Architecture, Engineering, Construction
AEC software developers who already know your stack: Revit, Navisworks, Civil 3D, AutoCAD, APS, BIM 360, Autodesk Construction Cloud.
MEP
Mechanical, Electrical, Plumbing
Systems coordination, clash detection tooling, and model-based QA / QC software built for the way MEP engineers actually work.
RE
Real Estate and Property Tech
Portfolio platforms, investor-facing dashboards, and underwriting tools. The business case carries through to production.
from idea to production
Selected AEC software work.
AEC · MEP
HVAC modeling platform · DCNE
What started as an Autodesk Forge Viewer proof of concept grew into DCNE’s own modeling tool for floor plans and HVAC systems. Their engineers design inside software shaped around how they work.
AEC · AI
Revit export plugin · generative AI design platform
A generative AI design platform needed its output to land directly as an Autodesk Revit file. Architects who use it now open something familiar on day one, and the platform keeps users inside its own product.
AEC
Autodesk Construction Cloud portal · AEC firm
An AEC firm’s project archiving used to take thirty minutes of manual searching. Lagarsoft built a portal connected to Autodesk Construction Cloud that surfaces the information on demand. The workflow now takes seconds.
how we engage
Every phase of the lifecycle.
The first meeting is the Build Audit. From there, the work runs as an Embedded Pod: scoped, adjusted as it unfolds, and shaped by what is actually shipping.

why us
Why pick Lagarsoft as your AEC software development company.
Domain depth, not generalists
Ten years of AEC custom software development. Founders out of WeWork and CASE Inc. Autodesk Platform Services Partner.
Production from day one
Boring databases. Boring queues. Boring caches. The systems we ship hold up under real production load.
Security is structural
Auth, secrets handling, dependency hygiene, and audit trails as baseline. Present before the first user touches the system.
Releases are uneventful
CI, observability, and a rollback path in place before the first deploy. Shipping should be the boring part.
faqs
Common questions.
What does an AEC software development company do?
An AEC software development company builds custom software for Architecture, Engineering, and Construction firms. The work spans BIM and Forge / APS integrations, Revit plugins, custom 2D and 3D web viewers, field-to-office data pipelines, and internal platforms that automate the parts of the workflow Revit, AutoCAD, Navisworks, or Autodesk Construction Cloud do not cover out of the box.
How is AEC custom software development different from generic SaaS development?
The domain matters as much as the code. AEC software developers have to read floor plans, understand clash detection, know how Revit families behave, and ship inside the constraints of APS, BIM 360, and the file formats the industry actually uses. A generic SaaS team can write the CRUD; the AEC parts are where projects stall.
Do you work with Autodesk Platform Services and Autodesk Forge?
Yes. Lagarsoft is an Autodesk Platform Services Partner. We ship Viewer integrations, Model Derivative pipelines, Data Exchange flows, Design Automation jobs, and AEC Data Model queries in production. Revit plugins too.
Do you serve MEP and real estate clients in addition to AEC?
Yes. AEC is the centre of gravity, and MEP and real estate / property tech share enough of the workflow that the same engineering bench covers both. Systems coordination, clash detection tooling, portfolio platforms, and investor dashboards are all on the menu.
What does an engagement with Lagarsoft look like?
Every engagement starts with a Build Audit: a forty-five-minute working session with senior engineers, followed by a one-page memo signed and dated within forty-eight hours. The memo is yours to keep. From there, work continues as an Embedded Pod: senior engineers on a sprint cadence, scoped work, transparent management.
Where is Lagarsoft based, and who do you work with?
US company, Uruguay-based, globally distributed. We work with AEC firms, MEP consultancies, real estate operators, and AEC software founders across North America, Latin America, and Europe.
