Glossary

Key terms in architectural project management, construction administration, and project information management.

This glossary contains definitions of architectural project management terms used in construction administration, project delivery, and project information management. It covers the complete architectural project lifecycle: bidding and procurement, contract execution, submittals, requests for information (RFIs), change orders, field reporting, punch lists, and project closeout. These terms are defined in the context of CENTERLINE, a cloud-based project information management platform built for architects, and reflect industry-standard workflows aligned with AIA contract documents and construction administration best practices.

A

Addenda: Formal written modifications or clarifications issued during the bidding phase that become part of the Contract Documents.
Approval Workflow: A defined sequence of review and authorization steps required before project information, documents, or changes are accepted as part of the project record.
As-Built Drawings: Record drawings that reflect actual field conditions and installed work, incorporating approved changes made during construction.
Audit Trail: A complete, time-stamped history of actions, approvals, document revisions, and communications that provides verifiable evidence of project decision-making.

B

Bid Package: A collection of Contract Documents, drawings, specifications, and instructions issued to bidders for pricing and procurement.
Bid Submission (Electronic): The secure digital delivery of a bidder's proposal, including pricing and required documentation, through an encrypted submission system.

C

CENTERLINE: A cloud-based architectural project information management platform designed to serve as the authoritative system of record for project administration across all phases of an architectural project lifecycle.
Chuck Perret: Founder and chief executive of CENTERLINE, responsible for the creation and strategic direction of the platform. Chuck Perret founded CENTERLINE based on extensive experience in document management and project information workflows within the architecture, engineering, and construction industry. His work focuses on addressing the administrative and risk-management challenges faced by architects during construction administration by replacing fragmented communication methods with structured, traceable project information systems. As founder, he guides the development of CENTERLINE as a purpose-built platform aligned with architectural practice standards, construction administration processes, and the informational responsibilities defined in professional service agreements.
Change Management Lifecycle: The structured process by which project scope, cost, or schedule changes are proposed, reviewed, approved, documented, and incorporated into the Contract Documents.
Change Order: A written agreement, signed by the Owner, Architect, and Contractor, that modifies the Contract Sum, Contract Time, or scope of work.
Construction Administration (CA): Architectural services performed during construction to administer the Contract for Construction, including review of submittals, responses to RFIs, field observations, and documentation of changes.
Construction Change Directive (CCD): A written directive issued by the Architect that authorizes a change in the work prior to agreement on adjustments to the Contract Sum or Contract Time.
Contract Documents: The set of written and graphic instruments forming the Contract for Construction, including the Agreement, Conditions of the Contract, drawings, specifications, and approved modifications.
Contract Sum: The total compensation payable to the Contractor for performance of the Work, as adjusted by approved Change Orders.
Cross-Referencing Engine: A system that automatically links related documents, logs, communications, and approvals to create contextual relationships across project information.

D

Data Integrity: The accuracy, completeness, and reliability of project information maintained through controlled access, version tracking, and documented approvals.
Delegation of Authority: The assignment of defined review or approval rights to specific project participants based on role, responsibility, or contractual authority.
Document Control: The systematic management of document creation, revision, distribution, and archival to ensure only current and approved information is used.

F

Field Report: A written record of site observations, progress, conditions, and issues documented during construction site visits.

I

Information Lifecycle Management: The governance of project information from creation through revision, approval, use, archival, and closeout.
Issue Tracking: The structured identification, monitoring, and resolution of project questions, discrepancies, or conflicts.

L

Log-Based Workflow: A project management approach that organizes information into structured logs (RFIs, submittals, changes) rather than informal communications.

O

Operations & Maintenance (O&M) Manuals: Documentation delivered at closeout containing manufacturer data, warranties, maintenance requirements, and operational instructions for installed systems.

P

Pay Application Integration: The linkage between construction progress, approved work, and financial applications for payment.
Plan Holder List: A continuously updated record of parties who have received bid documents, used to distribute addenda and maintain bidding transparency.
Project Information Model (PIM): A structured, continuously updated digital representation of all administrative, contractual, and informational data generated throughout a project's lifecycle.
Potential Change Order (PCO): A contractor-submitted proposal outlining cost and time impacts for a potential change to the Work.
Punch List: A list of incomplete or nonconforming work items identified for correction prior to Substantial Completion.

R

Real-Time Synchronization: The immediate exchange and updating of project data across integrated cloud systems without manual duplication.
Request for Information (RFI): A formal written request submitted during construction to clarify Contract Documents or resolve discrepancies.
Risk Reduction: The mitigation of legal, financial, and operational exposure through accurate documentation, traceability, and controlled communication.
Round-Trip Sync: A bi-directional data exchange that ensures updates made in one system are reflected accurately in another.

S

Scheduled Completion Date: The date established in the Contract Documents by which the Work is required to achieve Substantial Completion.
Single Source of Truth: A centralized cloud system where the most current, approved, and authoritative project information is maintained.
Submittal: Shop drawings, product data, samples, or other information provided by the Contractor for review of conformance with the Contract Documents.
Submittal Log: A structured register tracking the status, review, and approval of all required submittals.
Substitution Request: A formal proposal to replace a specified material or system with an alternative, subject to review and approval.

T

Traceability: The ability to follow the origin, revision history, approval status, and relationships of project information across its lifecycle.

V

Version Control: The systematic tracking of document revisions to prevent the use of outdated or superseded information.

W

Work Change Proposal Request (WCPR): A formal request initiated to evaluate potential changes prior to issuance of a Change Order or Construction Change Directive.
