FACILITIES MODEL USE - VGG – DESIGN AND COORDINATION
As-builts for the VGG project showing MEPF, Framing, Structure, Civil and Architecture models. All edited per COBIE standards
COBIE REQUIREMENTS FROM CLIENT - VGG
Top: Required fields from LACCD COBIE standards. COBIE is a method of exchanging data in BIM models. Bottom: Fields listed in Revit models. (to be completed). Each piece of installed equipment will have this field filled in the model.
REQUIREMENTS - VGG - SPACES
Top: Space plans from model. Spaces will establish schedule boundaries for generating in-place equipment information. Bottom: Section showing height clearance for space in a room. Each space needs to be fully enclosed to function properly.
REQUIREMENTS - VGG - SCHEDULES
Schedules created in spreadsheet format from model to provide equipment data. Each space or room will be in a schedule per trade showing all the equipment available as a sort of index. The schedules will be used as a reference to quickly sort through the availability of equipment and warranties in the model instead of a hard copy.
APPLICATION -VGG - EQUIPMENT
Facilities technicians can navigate the equipment in their buildings based on the provided model and data using tablets and software like Bentley Projectwise
SITE LOGISTICS PLAN - FIFTH & OLIVE
Site logistic plans are used in the construction industry to demonstrate the intent of the builder’s use of the project area. Explanation of excavation plan - these plans are submitted to the client and city to show how we meet construction operation guidelines
SITE LOGISTICS PLAN - FIFTH & OLIVE
Explanation of foundation plan - Construction equipment and street closures are depicted for city planning review
SITE LOGISTICS PLAN - FIFTH & OLIVE

John Anson Ford Theatre 30,000 SF, 1200 seat performance venue. $66 Million Renovation and Expansion. John Anson Ford Theatre renovation and expansion required modeling and coordinating a building about a hundred years old with many potential site issues. Modeling of project including the new building then Navisworks coordination reduced RFI.

NAVISWORKS COORDINATION - THE EDITION
Rendering of completed building.
Navisworks composite model.
The Edition - West Hollywood 300,000 SF, 13 floors and 148 hotel rooms. $300 Million New Construction. The Edition is built on a challenging site along Sunset boulevard. The tight constraints require constant coordination to make sure the building will be free of time consuming review meetings.
NAVISWORKS COORDINATION - THE EDITION
Typical hallway condition and equipment above and below.
Level 4 of the building. The section is an example of all the systems that are coordinated on the horizontal and vertical planes week to week.
Clash between a beam and HVAC equipment.
NAVISWORKS COORDINATION - THE EDITION
Clash between Mechanical and Electrical equipment. The building is still being coordinated and expected to meet a 2018 completion.

NAVISWORKS COORDINATION - KAISER MURRIETA
Kaiser Murrieta MOB had a 12 month completion time and coordination was vital. Section displaying building systems and equipment under roof.

NAVISWORKS COORDINATION - KAISER MURRIETA - MEPF
Combined MEPF model for the entire building - fully coordinated. Tolerances within half an inch are common throughout the tightly packed building. All of the structural, architectural, MEPF and interior systems were fully coordinated before construction.

After all the models were coordinated less than two dozen RFI’s reported during construction.
REALITY CAPTURE - EQUIPMENT
Scanner unit, Carrying case, Portable PC, Memory card Faro Focus 3D system is used together with Scene software to create 3D point clouds that record the existing environment of a given space. These point clouds can then be used to coordinate with a new set of changes with enhanced accuracy compared to traditional surveying methods.
REALITY CAPTURE IN OPERATIONS – CITY NATIONAL PLAZA NORTH TOWER (PAUL HASTINGS TOWER) Owner needed as-built survey to study sizing for new passenger elevator. Recorded levels 50-52 with Faro Scanner in 1 day.
Point Cloud Section of Composite scan from levels 50-52 in CNP North building.

3D MODEL OF THE SCAN IN NAVISWORKS SUPERIMPOSED ON CONCRETE MODEL TO BE USED AS A REFERENCE IN COORDINATION
SAME AREA AS ABOVE VIEWED IN 3D POINT CLOUD ENVIRONMENT
As an additional QA/QC measure to go above and beyond standard practices to make sure key areas were thoroughly coordinated. A 3D scan beneath the stage of OS2 was created. This allowed us to accurately locate openings for key MEPFS systems during coordination saving both time and money by allowing us to route systems to the correct locations and elevations per the scan.
REALITY CAPTURE – FORD THEATRE – AS-BUILT RECORDS
Left: Post-pour scan point cloud overlaid on Navisworks model. Aligning the point cloud and models accurately is essential to accurate coordination. Right: Equipment as modeled compared to as-built scan showing a clash between the concrete and pipes. Finding issues like these would be difficult without a point cloud of the existing conditions.
REALITY CAPTURE – FORD THEATRE – INFORMING MODELS
Left: Clash between modeled ducts and actual position of as-built catwalk supports compared to modeled supports. Modeled supports from design documents are shown to be inaccurate compared to the actual condition. Issue was noted and resolved before installation of large ducts. Right: Beam shown was added in after point cloud indicated where it should be. Prior to this there was no beam or it was assumed to be lower. Finding this issue early led to design revisions instead of waiting until installation was underway.
REALITY CAPTURE – FORD THEATRE – TOPOGRAPHIC DATA
South and North elevations of proposed sound wall compared to existing hillside captured from scan. These scans along with the model can help coordinate the project in areas of limited access.
IMPROVING CONCRETE FINISH RESULTS AT KAISER MURRIETA - SCAN SETUP Situation: Client requested an improved process from contractors showing floor flatness results. The solution was using point clouds and third-party apps to create a heat map of the concrete for easy readability.
3D scan capture of column with target. These targets are essential for aligning the scans to the elevation. The elevation is needed for accurate topographic results.
Photo from scanner displaying ground level. The scanner can take photos as well as 3D data. These photos are useful reference documents.
REALITY CAPTURE CONCRETE – PLANNING STAGES Next step is to plan out the scanning process. This scan takes place as the concrete is poured so timing is crucial.
Step 1 – Establish concrete pour plans
Step 2 – Create path of pour for crews
Step 3 – Create line of travel with scanner following pour path
Step 4 – Scan slabs for floor flatness and process results
REALITY CAPTURE - FINISHED CONCRETE - RESULTS
Heat map created with SCENE & Rithm App displaying concrete floor highs in red and lows in blue based on As-builts. Effort required: 4-8 hrs. Now the client has a complete topographic map of the concrete floor flatness of this project for ease of study. Kaiser was very satisfied with the results.
