About the client

The client is a national interdisciplinary design and engineering firm that provides planning, architecture, engineering, and consulting services for complex facilities across healthcare, government, and community sectors. The organization employs more than 1,000 professionals and delivers projects ranging from large healthcare campuses to public infrastructure and institutional facilities.

As part of their architectural and facility assessment services, the firm performs extensive building inspections and space programming analysis to understand how existing facilities are used and how they can be improved or redesigned.

Business challenges

A key component of facility analysis involves documenting existing building conditions. During inspections, teams capture large sequences of photographs covering each space, including room numbers, layouts, and installed equipment.

However, the analysis process was largely manual and time-consuming.

Typical workflows required teams to:

Walk through facilities and capture hundreds or thousands of photographs
Review image sequences and manually determine where one room ends and another begins
Identify and record room numbers from signage
Classify each space by type and subtype (e.g., office, lab, auditorium, mechanical room)
Document all equipment and objects present in the room

Processing this information manually created several challenges:

Slow audit workflows that could take weeks to complete
High labor costs due to manual image review and data entry
Inconsistent classification depending on individual reviewers
Limited scalability when projects involved large facilities with thousands of rooms

The client wanted to modernize the workflow using AI while preserving the existing field inspection process used by their teams.

Goals set to Achievion

Achievion was engaged to design and develop an AI-powered system capable of automatically interpreting inspection photo sequences and transforming them into structured building information.

Key objectives included:

Automatically separate chronological photo streams into distinct rooms
Detect and extract room numbers from signage using computer vision and OCR
Classify rooms by type and subtype based on visual characteristics
Identify equipment and objects within each space
Deliver results through an easy-to-use interface integrated with the client’s cloud environment

The ultimate goal was to significantly reduce manual processing effort while improving consistency and accuracy in building inspection documentation.

Solution

Achievion designed and implemented an AI-powered computer vision platform that automates the analysis of building inspection photographs and converts visual documentation into structured facility data.

The system combines several AI models—each responsible for a specific task—into a unified pipeline that processes inspection photo sequences and extracts meaningful information about rooms, signage, and equipment.

Key features of the product in detail

Photo Sequence Segmentation

The first stage of the pipeline analyzes chronological photo sequences captured during facility walkthroughs.

An image classification model identifies room signage within the sequence and uses these markers to determine where one room ends and another begins. This allows the system to automatically group photos belonging to the same space without requiring manual sorting.

Room Number Detection

Once room label images are detected, the system extracts the room number from the signage.

Optical character recognition models convert the text visible on room labels into structured identifiers. These identifiers are then associated with the corresponding set of room images in the inspection dataset.

This step allows each detected space to be automatically labeled with its correct room number.

Room Type Classification

After identifying a room, the system analyzes images of the space to determine its functional type.

The AI models evaluate visual features from multiple photos of the same room and classify the space into predefined categories such as offices, laboratories, auditoriums, or technical rooms.

Predictions from multiple images are aggregated to improve classification reliability and reduce the impact of ambiguous or incomplete views.

Equipment and Asset Detection

In addition to room classification, the system identifies equipment and infrastructure elements visible in each space.

Computer vision models detect objects within the images and return their location and category. This allows the system to automatically document equipment such as technical installations, workstations, or specialized infrastructure components.

Detected objects are stored as structured records linked to the room where they appear, creating a detailed digital inventory of building spaces.

Unified Workflow and Interface

All AI capabilities were integrated into a single workflow accessible through a web-based interface.

The system automatically processes photo sequences stored in the client’s cloud environment and returns structured results, including:

Room boundaries and room numbers
Room classifications
Detected equipment and assets

The results are presented through an interactive interface that allows teams to review inspection outcomes and export structured datasets for further analysis.

The platform was deployed in the client’s private cloud environment to ensure compatibility with existing workflows and security requirements.

Business outcome

Achievion delivered an AI-powered inspection analysis pipeline that converts building photo documentation into structured facility insights.

Key outcomes:

Inspection analysis reduced from weeks to minutes
Lower operational costs by eliminating large portions of manual image review
More consistent and reliable classification of rooms and equipment
Scalable automated workflow capable of processing large inspection datasets

The solution preserved the client’s existing field inspection process while dramatically accelerating the analysis phase and improving the reliability of building documentation.
