CARNEGIE LIBRARY · PITTSBURGH, PA

Carnegie Free Library

Pointknown provided reality capture and existing-conditions modeling services for the historic Carnegie Free Library of Allegheny as part of its transformation into MuseumLab, an extension of the Children’s Museum of Pittsburgh created for older youth focused on art, technology, and creative exploration. The project required accurate documentation of a 45,000-square-foot historic structure to support adaptive reuse planning and future design work.

Planning, Coordination & Reprogramming
Measured once. Delivered ready for design.
The Challenge
Adaptive reuse projects demand more than field measurements. They require a clear understanding of how an existing building is actually put together. For this project, the building’s historic fabric, large-volume spaces, and varied conditions called for a capture strategy that balanced speed, coverage, and precision. The design team needed a model they could actually design from — not just a cloud of data, but an organized existing-conditions foundation that supported planning, coordination, and reprogramming.
What was documented
Our team documented the building’s interior and exterior conditions using a combination of terrestrial laser scanning and SLAM-based mobile capture technologies. Heavy masonry construction, Romanesque Revival architectural details, arched openings, towers, stair systems, roof forms, and complex multi-level interior spaces were captured and organized into a unified dataset suitable for downstream modeling and design.
What was delivered
Pointknown delivered a coordinated Revit existing-conditions model developed from registered point cloud data. Supporting outputs included organized point cloud datasets along with plans and sections generated from the model to assist architectural planning, coordination, and adaptive reuse design workflows.
Why it matters
When a historic building is being carefully reimagined, the design team needs dependable existing-conditions information from the start. On projects like this, Pointknown helps teams move from complex existing conditions to practical design intelligence — a clearer basis for planning, coordination, renovation, and adaptive reuse. This is one of our favorite types of work: a grand old building, documented carefully, so it can be given a new life in service of the public.
Allegheny Square Context

Capture that supports the building and the site around it.

For adaptive reuse work, the building is only part of the story. Access, entries, surrounding grades, sidewalks, and site context all shape how a project moves forward.

OUR APPROACH

Terrestrial + SLAM capture, working together

Pointknown used a combination of high-definition terrestrial laser scanning and SLAM-based mobile scanning to document the building efficiently and thoroughly. Terrestrial scans were used to capture key exterior and interior conditions with precision. SLAM scanning helped cover the full interior more efficiently. The datasets were then registered into a unified point cloud and used to build the Revit existing conditions model.

Exterior + key interior scan coverage for high-confidence geometry.
SLAM capture for efficient interior documentation.
Useful for renovation planning, consultant coordination, and campus-wide reference.
Unified point cloud organized for modeling and coordination.
Revit existing conditions model delivered for design use.

Then + Now

A Civic Building with another chapter ahead

The former Carnegie library became MuseumLab — a place for older youth to keep creating, experimenting, and learning.

GRAND OLD BUILDING

Measured for a new public life

Some projects stand out because the work goes beyond documentation. This was one of them.

The former Carnegie Free Library of Allegheny was being transformed into MuseumLab, an extension of the Children’s Museum of Pittsburgh created for older youth to explore art, technology, making, and creative learning.

Pointknown was brought in to document the building and create a reliable Revit model of the existing conditions so the design team could move confidently into planning and design.

Historic buildings are full of surprises. Good design decisions start with accurate information.
PROJECT HIGHLIGHTS

A complete existing conditions package, from reality capture to usable deliverables.

This project combined high-definition terrestrial scanning and SLAM capture workflows to balance precision and efficiency. Terrestrial scans documented key architectural elements with a high degree of detail, while mobile scanning accelerated broader interior coverage. Together, the datasets created a coordinated representation of the building that enabled architects and planners to move from documentation directly into design.

WHY POINTKNOWN

The value is not in the scan itself. It is in what your team can do next.

Design-ready deliverables

Measured information is structured into clean Revit and CAD outputs so architects, owners, and developers can move quickly.

Clear communication

Pointknown focuses on clarity. The process stays in the background. The usable result stays front and center.

One source of truth

A single field effort supports visualization, planning, modeling, and documentation—without repeated site visits or fragmented information.
