Accurate . . . so that there is good communication between all your team members. Stakeholders, subcontractors, builders – they all need detailed drawings that they can depend on. From bidding the project, all the way through construction, accurate drawings will mean a superior project.
SOLUTION: Using Revit and BIM methods will introduce several tools that provide “checkpoints” for accuracy.
- Reference planes allow you to “lock” objects and dimensions, so that you are warned when they change or move.
- Dimensions are always “true”, because they are inherently tied to their reference. No “faking” dimensions any more.
- Section tags and other references are directly referenced to where they are cut, and the sheet where they are placed. When you move or renumber a tag, its reference is changed in every other location. So you don’t have to check every sheet to make sure everything is up to date.
Integrated . . . Construction projects are complicated, especially when you have many people working on the same project. This leads to errors and omissions when changes are made. It is time consuming to check all the drawings to make sure the proper changes are made throughout the entire set.
SOLUTION: The primary component of Revit is that it is fully parametric. This means that any changes you make to the model are coordinated throughout the entire project.
- Move an exterior door in the plan? Its new location is automatically updated in every other view that contains it. Change the door’s style or size. That is also updated on the schedule.
- Major changes often happen during the course of a building project. Maybe the height changes from floor to floor. In a standard drawing set this means spending a lot of time changing things, and create a huge risk that something would be missed. If you have tied things together correctly, with Revit many items (walls, doors, floors) and their associated dimensions would move automatically with one change to the height.
Coordinated with other team players . . . One of the challenges in our industry is making sure all the players are on the same page. How many times has a project been held up or went over budget because the documents were confusing, or lacked the proper coordination?
SOLUTION: Using Revit on a project can assist with the coordination of the entire project.
- Revit provides a tool called “worksharing” that allows all your internal team members to access the model at the same time. The project is being constantly updated – everyone can see the changes in real time. No more “silo” work that has to be combined at the last minute.
- You can also team up with other disciplines involved in the project (Structural Engineers, MEP, etc.) – either by using a “live” model that everyone can access, or combining all the work in one model. Either way, the coordination is valuable because you can identify problems early in the process before they become more intrusive and expensive.
Created and coordinated by an expert . . . There is a big difference between “pretty” schematic drawings, and accurate drawings that can be used to build the project. While schematic drawings are useful for obtaining the project and its funding, it takes a different set of skills to put together a cohesive set of CDs that communicate the project’s intent well and accurately. Someone who has years of experience with this type of drawing and communication, and can also apply all of the above advantages over the course of your project.
