Design-Build¶

Project delivery method where a single entity holds contracts for both design and construction. Intended to reduce project risk and delivery time by fostering collaboration.

Edge Computing¶

Processing data near the source of generation rather than in centralized cloud servers. In construction, enables real-time jobsite analytics even with limited connectivity.

Embedding¶

Numerical representation of text, images, or other data in a high-dimensional vector space where semantically similar items are located near each other. Enables AI to understand meaning and context.

Fine-Tuning¶

Process of training a pre-existing AI model on domain-specific data to improve performance on specialized tasks. In construction, might involve training on project documentation, specifications, or technical standards.

GC (General Contractor)¶

Prime contractor responsible for overall construction project execution. Manages subcontractors, schedule, budget, and coordination between all trades.

Hot Aisle / Cold Aisle¶

See Cold Aisle / Hot Aisle.

Hyperscaler¶

Companies operating massive-scale data centers and cloud computing platforms (e.g., Amazon AWS, Microsoft Azure, Google Cloud). Major drivers of data center construction demand.

IBC (International Building Code)¶

Model building code addressing structural and fire safety for all building types. Adopted by most US jurisdictions as basis for local building codes.

IFC (Industry Foundation Classes)¶

Open, vendor-neutral data format for exchanging BIM information between different software platforms. Enables interoperability across the construction technology ecosystem.

Immersion Cooling¶

Data center cooling method where servers are submerged in thermally conductive dielectric liquid. Enables much higher rack densities than air cooling.

IPD (Integrated Project Delivery)¶

Collaborative project delivery approach where owner, architect, and contractor share risk and reward. Incentivizes whole-project optimization rather than party-specific goals.

Knowledge Graph¶

Structured representation of information as entities and their relationships. Enables AI to understand connections between concepts, projects, people, and processes across an organization.

Lean Construction¶

Application of lean manufacturing principles to construction. Focuses on maximizing value and minimizing waste through collaborative planning and continuous improvement.

Liquid Cooling¶

Data center cooling using liquid instead of air to remove heat from servers. Includes direct-to-chip cooling and immersion cooling, enabling much higher power densities.

LLM (Large Language Model)¶

AI model trained on vast amounts of text data to understand and generate human language. Examples include GPT-4, Claude, and Gemini. Can be applied to construction document analysis, specification writing, and knowledge management.

MasterFormat¶

Standardized system for organizing construction specifications and cost data. Divides work into divisions (e.g., Division 03 Concrete, Division 23 HVAC) with hierarchical numbering.

MEP (Mechanical, Electrical, Plumbing)¶

Building systems including HVAC, electrical power and lighting, plumbing, fire protection, and controls. Represents significant coordination complexity in construction projects.

AI systems that can process and integrate multiple types of input (text, images, audio, video). In construction, enables analysis of drawings, photos, specifications, and reports simultaneously.

NFPA (National Fire Protection Association)¶

Organization publishing codes and standards for fire prevention and life safety, including NFPA 70 (National Electrical Code) and NFPA 101 (Life Safety Code).

NLP (Natural Language Processing)¶

AI techniques for understanding, interpreting, and generating human language. Used in construction for analyzing project documents, specifications, and communications.

PDU (Power Distribution Unit)¶

Device that distributes electrical power to servers and equipment in data centers. Provides power monitoring, remote control, and backup power integration.
