1.2CityofSanAntonio BuildingInformationModeling(BIM)LifeCycleVision

The City of San Antonio (CoSA) has determined that Building Information Modeling (BIM) represents both an

enhanced technologyandaprocesschange for thearchitectureengineeringconstructionfacilitiesmanagement

industry.CoSAiscommittedtomovingboththeCityanditsserviceproviderstoBIMaseffectivelyandefficiently

BIMPROJECTREQUIREMENTS,STANDARDS,

PERFORMANCECRITERIA,INFORMATIONINTEGRATION

2.1General

Thefollowingsectionestablishestheminimumrequirements,elements,and informationthatmustbecontained

inthe

BIM

model.

The

CoSA

BIM

Standards

will

include

requirements

for

development

of

the

3D

BIM

model

and

for the generation of the 2D design and construction document drawing sheets using standardized templates.

Mandatory BIM project requirements shall include the modeling, visualization, documentation, building

information content, and analytic processes of the building design and shall assist in validating the material

quantitiesandconstructioncostoftheproject.

Theprincipal objectiveof incorporating BIM is to improve thequalityof the design solutions and expedite the

sequenceofconstruction.TheCoSABIMStandardswillresult inprojectsachievingahigher levelofconsistency,

quality,accuracy,andcompleteness. Therequiredprojectinformationshallbekeptwithinasingledatabasefile.

CoSA will be using the OmniClass table structure to classify attributes of the model (i.e. Labeling / Identifying

Spaces, Work Results and Products, Phases and Disciplines). These categories are identified throughout this

standard.For

2.12.6SchedulingandSequencing

constraints such as procurement lead time/logistics, resources, spatial constraints, and weather among others.
