BIM is a processAnd the process needs to be planned and documentedDon’t blame the software if you don’t

COLLABORATION NEEDS SMART PEOPLE

•Define your key people

•Make sure key roles have backup

•Exchange knowledge and ideas early

•Don’t make rules and procedures up as you go

•Have a set of documents defining them ready to share

You’ve got your preliminary BIM Project planning do neNow you need to get started in Revit

Project Setup (Linking) Schematic Plan (PowerPoint or similar so its easy to amend)

If you are the model manager the makeup of your model linking

structure and coordinate propagation layout may be obvious.

What is happening when you are not in the office, how will your consultants know?

Create a schematic model structure to

reveal the linked project relationships.

Start early and update as changes

happen. Planning and

setup mistakes are the base of most

BIM project hardships.

SETUP WORK SHARING AVOID THE PITFALLS

The Schematic Model Structure

Document is also a good reference

for file naming and your work-set

naming .

Make sure your work-set naming is

aligned with all Consultants

Avoid too many work-sets they will

only create unproductive work.

But make sure all links are on a

separate Link_workset

WORKING WITH STRUCTURAL CONSULTANTS

Golden Rules:

ALL TEAMS SHOULD BE ON THE SAME VERSION AND BUILD OF REVIT.

•Filenames should remain always consistent

•As per Project Setup Schematic Plan

•RVT project files should be archived for each Major Model Revision providing a history of issued RVT files

•All Structural and MEP Models should be linked origin to origin

•All models should have the shared coordinate system applied but should not be used for linking.

WORKING WITH STRUCTURAL CONSULTANTS

Team Process:Basic

•The ARCH team creates a grid*, levels, columns, slabs and walls

•The STR team starts by linking the ARCH file origin to origin

•The STR team then pins the linked ARCH Project

•The STR team copy monitor levels from ARCH Model

•The STR team deletes any redundant remaining levels from the original file

•The STR team checks Project_ Level 00_ is 0,00 (Project/ Elevation Base) (or check with the ARCH team if an

exception is found). Level 00 is the Base level and should never be moved.

•The STR team sets Levels to Shared (Elevation Base)

•The STR team acquire coordinates from ARCH model

This Grid may not be based on the structural layout of the building, but has been positioned temporarily by the

architect to provide a starting point.

Experience on 40+ collaboration projects has shown that copy monitor of levels and grids with structural consultants

is sufficient. Copy Monitor of floors, walls and columns is generally fraught with problems.

See next page.

COPY-MONITOR STRUCTURE

There are various rules that must be

considered for the above categories

that determine whether the

monitor will flag a change or not

these are as follows:

Monitor Rules

Monitor flags change?

Monitoring in Revit

Revit Structure is limited to monitoring 5 categories these are;

• Levels

• Grids

• Columns

• Walls

• Floors

*Yes for core component of the wall

** Yes for width of slab

WORKING WITH MEP CONSULTANTSTeam Process:Basic

•The MEP team starts by linking the ARCH file origin to origin

•The MEP team then pins the linked ARCH Project

•The MEP team copy monitor levels from ARCH Model

•The MEP team deletes any redundant remaining levels from the original file

•The MEP team checks Project_ Level 00_ is 0,00 (Project/ Elevation Base) (or check with the ARCH team if an

exception is found). Level 00 is the Base level and should never be moved.

•The MEP team sets Levels to Shared (Elevation Base)

•The MEP team acquires coordinates from the ARCH model

•Grids may or may not be transferred depending on workflow

•The ARC team has set up Linked Views as backgrounds for the MEP consultants

•Early communication on what views and what model information is needed is invaluable

Team Process:Advanced

•To align fixture positions with the architectural model and keep it up to date, the mechanical engineer can use

Copy/Monitor to copy fixtures to the MEP project. If the architect adds, removes, or changes fixtures, Revit

MEP notifies the mechanical engineers of the changes. They can then update the MEP project, as appropriate.

COORDINATING VIA COPY MONITOR WITH MEP CONSULTANTS

But this is not as easy as it looks

This is where

In a Revit MEP project,

you can copy and monitor the following types of MEP elements from an architectural project:

•Air terminals

•Communication Devices

•Data Devices

•Electrical Equipment

•Electrical Fixtures

•Fire Alarm Devices

•Lighting Devices

•Lighting fixtures

•Mechanical equipment

•Nurse Call Devices

•Plumbing fixtures

•Security Devices

•Sprinklers

•Telephone Devices

CollaborationCoordinationCommunication Is a must

For Architects •A GPO, Light Switch, Fire Alarm Button is all an Electrical Fixture (We kind of guess it is not Equipment)

Electrical Fixture

•HSL-Call Emergency-3D

•HSL-Call-Intercom WM-3D

•HSL-Data-Outlet-3D

•HSL-DCO_3D

•HSL-LightSwitch-3D

COMMUNICATION VIA COPY MONITOR

For Electrical Engineers Its more something like this

NURSE CALL DEVICES

•HSL-Detail-Nurse Call Light

•HSL-Call Emergency-3D

•HSL-Call-NurseAssist-3D

•HSL-Call-PatientHandset-3D

•HSL-Call-PatientStaff-3D

•HSL-Call-Intercom WM-3D

DATA DEVICES

•HSL-Data-Outlet-3D

•HSL-DCO_3D

LIGHTING FIXTURES

•HSL-LightSwitch-3D

COPY MONITOR WITH MEP CONSULTANTS

But this is not the end

See what we get when the consultant copy-monitors

On top of this some consultants work differently from others.

So we need to talk to our consultant how they divide their fixtures and devices into categories

Architects link before copy monitor

Consultants link after copy monitor

MEP COPY MONITOR

Don’t use level based or work plane based

families with an offset parameter for

monitored MEP fixtures

Use face based families with no offset

parameter

WORKING WITH MEP CONSULTANTS

Got it!!
