BIM Unit 4

Coordination Model

A Building Information Model that is developed from a completed design. The creation of the model is an interpretation of a design as opposed to creation of a design.

Cost Model

A breakdown of constriction and project budget into detailed "cost targets". The construction budget is developed in both a detailed , component(S) based formats and CSI- based format to reflect the project's goals, detailed program, and performance requirements. The integrated team develops cost targets, collaboratively prior to commencing the conceptualization phase of the project process. The structure provides the benchmark for the team ot support continuous cost management as the project progresses to ensure that it will be completed within the targeted budget.

Selection Set

A collection of objects of any number or type that are desired to be viewed and/or manipulated collectively rather than individually. This set can be identified and preserved with a single nam`e.

United States Army Corps of Engineers

A leader in using BIM to improve delivery and management Systems.

Line of Balance Scheduling

A location based scheduling technique that graphically represents the planned and actual completion of activities based on site locations. The main benefits of the line of balance scheduling technique include easy identification of spatial scheduling conflicts and conflicts caused by unbalanced productivity rates in work crews.

Value Engineering

A process undertaken during the design phase in which elements or components of the design are evaluated for ease of constructability, and incorporate design features that provide comparable performance at better cost or schedule savings.

I Room (Smart Room )

A room that is set up for the purpose of facilitating quick and efficient interaction between project participants for planning, designing, and/or coordinating a project. These rooms typically have audiovisual devices installed that allow project participants to review models and make decisions.

Reverse Phase Scheduling

A scheduling technique that develops a schedule by working backward from a target completion date. This technique ensures that the schedule is sound and the project is constructible from a sequencing perspective. Also know as Pull driven scheduling or pull scheduling

Disruptive

A term used in business and technology literature to describe innovations that improve a product or service in ways that the market does no expect, typically lowering price or designing for a different set of consumers.

Design Assist

An approach to pre-construction where select subcontractors are engaged in consulting capacity to assist with providing design and/review services. The design assist subcontractors may or may not be selected for the actual construction of the project.

Cost Driver

An element that can have high variable costs depending on design decisions.

General Service Administration

An independent agency of the US government established in 1949 to help manage and support the basic functioning of federal agencies. The GSA supplies products and basic communications for U.S. Government offices, providers transportation and office space to federal employees, and develops government wide cost minimizing policies, among other management tasks.

Charrette

An intensive design review that involves the collaboration of all project stakeholders at the beginning of a project to develop a comprehensive plan or model.

Construction Coordination

An intensive process that involves the collaboration of all project stakeholders at the beginning of a project to develop a comprehensive plan or design.

Selection

An isolated object identified for the purpose of visualizing, clarifying, analyzing, transforming, or updating within the model environment.

Rendering Software

Applications that can provide a 3D interactive rendering of the project ( sketch up, autodesk 3ds Max, and power point)

Greenfield

Construction projects located on newly developed land. Because the land has not previously been developed, demolition of decontamination or other make ready projects is not required.

Co-opetition

Cooperative Competition. Occurs when companies work together to support part of their business where they do not believe they have a competitive advantage and believe they can share common costs.

Object families

Libraries of cut and paste templates for common design elements included in most BIM software. These libraries include common design features such as walls, roofs, windows, doors, and trim, stairs, railings, ramps, cabinets, landscaping, and light fixtures.

Parametric modeling system

Parametric models are object based rather than line based. This allows all of the objects in a model to be adapted simply by changing the reference file for that object, which allows all of the views to be changed automatically when one is changed.

Rendering

Photo realistic digital image with lighting conditions, material, textures, reflectivity, and shadows. ( Rendering is used for presentation, visualization, understanding, consensus, sales, marketing, and funding, etc. )

Building Information Modeling Process

The collaborative approach to executing a project where all parties work in a model-based environment with agreed up roles, responsibilities and vision. the process includes defined actions to facilitate a streamlined approach to delivering the project to the owner

Integration

The coming together of primary participants (which could include owner, designer, constructor, design consultants, trade contractors, key systems suppliers, etc ) at the beginning of a project for the purpose of designing and constructing the project as a team.

Designer

The design professional on the project responsible for performing and overseeing overall project design.

Roundtripping

The electronic exchange of model data from one party to another and then back to the first party. If interoperability has not been addressed, data maybe lost or modified inappropriately during the process.

Sustainability

The idea of sustainability, or ecological design, is to ensure that our actions and decisions today do not inhibit the opportunities of future generations.

Construction Plan(construction Planning)

The practice of identifying project objectives and necessary resources (eg personnel, materials, equipment, capital) then allocating them to maximum efficiency to execute a successful project. An actual construction plan document may or may not be created but the output of a construction plan is normally a schedule driven by cost resources and time

Forensic Modeling

The practice of using or creating a model of various levels of detail for the purpose of recreating a visual Representation of of actual events (usually of the onsite construction and installation activities)

Design Coordination

The process of ensuring that the various elements of the design )eg architectural, structural, electrical, etc) fit together and complement one another.

Synchronization

The process of updating the schedule and/or the model and updating the 4D model with new information.

Design Consultant

The professional Consultant on the project responsible for performing and overseeing design in specific areas of the work (eg structural, mechanical, landscape, electrical,civil,etc)

Adoption

To take up and practice or use

Process

Typically describes the act of taking something through an established and usually routine set of procedures to convert it from one form to another as a manufacturing or administrative procedure, such as converting computer data form to another.

Construction Manager with Pre-Construction Service

a CM engaged by an owner to assist before the engagement of subcontractors and start of construction to provide construction expertise to guide the design process and facilitate effective and efficient procurement of the project. Pre Construction services often consist of estimating scheduling constructability review, scoping, and buyout of the project.

Digital Data

is defined as information, communications, drawings, or designs created or stored for the project in digital form, which may be read on a computer.

Return on Investment

the amount of profit, before tax and after deprecation, resulting from an investment made, usually expressed as a percentage of the original cost invested. In the BIM environment profit is frequently reported as real dollars saved because of executing model based coordination and is measured against anticipated costs in the traditional process.
