Start with these
Building information modelling (BIM)
The use of a shared digital representation of a built asset — its geometry, properties and related documents — to support design, construction and operation decisions with reliable information.
Clash detection
The automated checking of a federated model to find places where elements conflict physically, violate required clearances or conflict in time.
Federated model
A combined model assembled from separate discipline or package models, each of which remains owned and maintained by its author.
Operation and maintenance manual (O&M manual)
The handover documentation that tells the owner how to operate, maintain and repair the building's systems and equipment, including product data, maintenance schedules, warranties and contacts.
Principal-in-charge (PIC)
The senior partner or principal of a consulting firm — typically architecture or engineering — who carries overall accountability for the firm's performance on a project and is the client's top-level contact.
Request for information (RFI)
A formal written question from the contractor to the design consultant asking for clarification of the contract documents — typically about design intent, an apparent omission or a conflict.
Shop drawing
A drawing, diagram or set of details prepared by a contractor, trade or supplier to show exactly how a specific part of the work will be fabricated and installed.
Trade contractor
A specialist firm that performs one part of the work — such as mechanical, electrical, masonry or curtain wall — under a contract with a general contractor, construction manager or owner.
Going further
Commissioning (Cx)
A quality-focused process that verifies and documents that a building's systems are designed, installed, tested and able to operate as the owner requires, and that operators are trained to run them.
Level of development (LOD)
A numbered scale (LOD 100–400, plus 500 in some frameworks) describing how far a model element's geometry and information have been developed — and therefore how much other team members can rely on it.
Level of information need
A framework for specifying the extent and granularity of information required for a purpose — covering geometry, alphanumeric data and documentation — so that no more and no less is delivered than is needed.
Task information delivery plan (TIDP)
A task team's schedule of the information containers it will produce, with responsibilities and delivery dates, for one appointment.
