AI & Construction Glossary

Official modifications to bid documents issued before bid opening. Addenda can change scope, clarify requirements, or modify contract terms. Must be acknowledged in bid submission. AI can help compare revisions.

Drawings and documentation that reflect actual installed conditions, including any deviations from original design. Required for project closeout and essential for future maintenance and renovations.

A formal document that modifies the original contract scope, schedule, or price. Results from design changes, unforeseen conditions, or owner requests. Proper documentation is critical for getting paid for extra work.

The general requirements section of construction specifications covering administrative and procedural requirements that apply to all trades. Includes submittal procedures, quality requirements, and project coordination.

Contract provisions that pass obligations from the prime contract down to subcontractors. Can include schedule requirements, insurance, indemnification, and dispute resolution terms. Critical to review before signing.

Clear statements in a bid or proposal defining what work is and is not included in the price. Critical for avoiding scope disputes and ensuring accurate bid comparison.

A formal solicitation from an owner or general contractor inviting subcontractors to submit pricing for a defined scope of work. The starting point for the bid process.

A systematic process for identifying potential hazards associated with specific tasks and determining controls to eliminate or reduce risks. Required for many construction activities, especially high-risk MEP work.

Pre-determined monetary penalties specified in contracts for failing to meet deadlines or other requirements. Important contract term that subcontractors should identify and understand during bid review.

The three major building systems that specialty contractors install and maintain. MEP subcontractors handle HVAC, electrical wiring, plumbing, fire protection, and related systems. A significant portion of construction project costs.

Documentation package provided at project completion that includes equipment specifications, maintenance schedules, warranty information, and operating procedures. Required for MEP systems closeout.

The phase of a construction project before physical work begins, encompassing bid review, estimating, scope development, value engineering, and contract negotiation. AI accelerates preconstruction by automating document review, requirement extraction, and deliverable generation.

A list of incomplete or defective work items that must be corrected before final project acceptance. Created during final walkthrough. AI can help create consistent, detailed punch lists.

Systematic processes for ensuring work meets specifications and standards. QA focuses on preventing defects through process controls. QC focuses on identifying defects through inspection and testing.

A formal document used during construction to clarify design intent, resolve conflicts in documents, or address unforeseen conditions. AI can help draft RFIs that get answered quickly by referencing relevant spec sections.

Gradual expansion of project scope beyond original contract requirements without corresponding adjustments to time or cost. Often results from unclear specifications or informal direction. Must be documented and addressed promptly.

Written requirements that describe materials, products, and workmanship standards for a construction project. Organized by CSI divisions. AI can help quickly find relevant requirements within lengthy spec documents.

Documentation submitted by contractors to demonstrate that proposed materials, equipment, or methods comply with contract requirements. Includes shop drawings, product data, and samples. AI can help build complete submittal packages faster.

The process of verifying that a contractor's proposed materials, equipment, and methods comply with the contract specifications and drawings. AI-powered submittal review automates requirement extraction and compliance checking, reducing the review cycle from days to minutes.

A contract or billing method where the contractor is paid for actual labor hours and materials used, plus markup. Common for change orders and work where scope cannot be precisely defined in advance.

The process of measuring and quantifying materials, labor, and equipment needed for a construction project by analyzing drawings and specifications. AI can accelerate takeoffs by extracting quantities from digital plans.

Brief safety meetings held at job sites, typically at the start of a shift, to discuss specific hazards and safety procedures. Required by many safety programs and OSHA compliance.

A systematic method for improving the value of a project by analyzing functions and identifying alternatives that reduce cost while maintaining or improving performance. In construction, value engineering evaluates materials, methods, and systems against project requirements to find savings without compromising quality.
