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

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.

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 - 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.

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.

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.
