MEP drafting & coordination
Architectural – Partitions: Our first step is to draw the partitions of the building. We work from PDF files that we convert and raise the walls up by half of their sizes, so we easily see all the trades in Navisworks™ without having walls blocking our point of view.
Architectural – Reflected ceiling: To ensure the coordination above ceiling heights, we also draw the ceilings. We draw ceiling tiles and exact lights locations, making sure to avoid any potential clash with recessed lights and allowing for enough access behind them.
Structural – Beams, joists, columns, slabs: After the layout of the floor, we carefully analyse the structure from the contract drawings and draw slabs, beams, joists and columns in 3D as well. This will allow us to make sure that all trades are clash-free with any structural element.
Trades – MEP, FP : Once done with the building layout, we start drawing the trades from the latest drawings received. We keep our trades as flat as possible and give a general elevation that we will edit during the coordination process. We coordinate:
- HVAC piping;
- Fire protection;
We assign a general elevation for each trade and try to keep all trade as flat as possible to reduce the cost of materials to our customers. Our goal is to coordinate and resolve all clashes prior to the contractors sending their costly crew on the field.
Clash detection: When responsible for all the MEP trades, we draw and clash-detect our work in our own self-proprietary software. This allows us to quickly see issues and edit our files during the clash detection. As a final step of our coordination process, we model the trades and can visually confirm that the design work.
BIM (Building Information Modeling): To ensure and easily visualize that the coordination proposed works, we model all our work: structure, architecture and trades. We add all those 3D models together into a Navisworks™ file document that we share to our customers. When working with other parties responsible for other trades, we add their models into our general model and clash-detect their work with ours.
RFI (Request For Information): In case of a design issue or a lack of space in the ceiling, we send RFI drawings to the Architect and Engineers for review, including suggestion(s) to fix the issue shown. We send those RFIs as soon as possible in the coordination process, in order to avoid any disruption in the field.
We provide our drawings in PDF formats and DWG formats (AutoCAD). To make it easy for the installation in the field, we provide all the necessary information on our plots:
- Equipment per approved submittals, which show proper access for maintenance;
- Sizes of each component of the trades;
- Exact dimensions from grids or walls to each component of the trades;
- Top, bottom and/or center elevation of the trades, offsets elevations;
- Length of each ductwork section, to allow mechanical contractors to pre-fabricate the ductwork (TDC, slip & drive);
- Reflected ceiling plans with ceiling heights elevations and lights locations;
- Structural beams and joists: sizes, elevations and slopes;
- Sleeves elevations and sizes;
- RFIs (Request For Information) sent in the form of a drawing with textual description of the issue, to request additional component information or report architectural design flaws, such as a lack of ceiling space to run the MEP trades.
Our as-built are included for free at the end of the project.
