Introduction
Project information that stops going missing
A building project moves thousands of files between many organisations. When each party keeps its own copy in email, on a hard drive or in a chat group, nobody can be sure which one is current. Codexa puts everything in one shared store that records who can see what, which version is latest and who approved it, and when.
- Files leave the project team only after they are checked and approved
- Reads the PDF and DWG drawings and Revit and IFC models that every party already works with
- File names are checked automatically against the project coding convention
- Issues, technical queries, site photos and schedules attach directly to drawings and models
Features
Nine feature groups in Codexa
Each group handles a familiar part of project work, and the data in every group can be connected to the others.
File naming codes
Define the naming structure once for the project. Files that do not fit are queued for correction instead of being turned away.
Version tracking
Look back over every update to a file and set two versions side by side to spot the differences, on drawings and models alike.
Drawing issues
Group drawings by dated issue, so you can tell which sheets were added, dropped or revised since the previous one.
Approval and handover
Set up review steps for each kind of document, give a decision on every file, then produce a handover record for the recipient.
Issues and technical queries (RFIs)
Mark a problem at its exact spot on a drawing or model, turn it into a question for the designers and follow it until it is answered.
Site imagery
Keep site photos and videos in albums, then browse them by position on a drawing or on a map.
Construction schedule
Bring in schedules built in MS Project, see what has shifted between updates and plan the coming week with site teams.
Registers and notifications
The whole project shares one register of zones and work items, and each person is notified only about their own work.
Connections
Every piece of information has context
A single site photo can be tied to the related issue, technical query, drawing and schedule task. Open any of them and the others are right there, so when a work item falls behind, the reason sits next to it.
- Discuss and call on the person responsible inside each item
- Tidy detail views, with fields not yet filled in folded away
- Time-consuming jobs run in the background and send an email when they finish
File formats
Which software files can Codexa open?
Project parties do not need to convert their files before uploading. These are the formats common in construction that Codexa can read.
BIM models and coordination
Revit models and family libraries, IFC files for exchange between BIM tools, and combined Navisworks files used for clash checking.
- RVT
- RFA
- IFC
- IFCZIP
- NWD
Drawings and CAD files
Issued PDF drawings, AutoCAD and Civil 3D files, DWF review sets, and MicroStation files common on transport and infrastructure projects.
- DWG
- DXF
- DWF
- DWFX
- DGN
Architectural massing and visualisation
Massing studies built in Rhino, ACIS solids exported from Revit, scenes made in 3ds Max and the 3D mesh formats used for presentation.
- 3DM
- SAT
- SAB
- FBX
- OBJ
- 3DS
- DAE
- GLTF
- GLB
Equipment and prefabricated parts
Machinery and MEP equipment models from manufacturers, steel details and prefabricated parts shared in neutral formats.
- STEP
- STP
- IGES
- IGS
For projects in Vietnam
Fits the way documents are handled in Vietnam
- Vietnamese interface and statuses Project administrators name the review outcomes in the words their teams already use.
- New status without renaming Status and revision are kept alongside the file rather than inside its name.
- Makes use of time-stamped photos When a photo has lost its original metadata, Codexa reads back the date and location stamped on it.
- Sheet numbers from file names No guessing from title blocks, which are easily misread on drawings with Vietnamese diacritics.
- Dependable schedule comparison Tasks are matched by their own codes, so adding new work in the middle does not skew the comparison.
- No mix-ups between old and new Upload a file whose name already exists and Codexa asks whether it is an update or a different file, and why it changed.
FAQ
Common questions about Codexa
What is a CDE?
CDE stands for Common Data Environment: the shared information store of a project. Every party reads and updates information from the same source, under version control and approval. ISO 19650 treats the CDE as the foundation of BIM information management.
Which file types can Codexa open?
PDF, DWG, DXF and DGN drawings; Revit (RVT, RFA), IFC and Navisworks (NWD) models; Rhino, FBX and OBJ geometry, and STEP or IGES equipment models. The full list is in the File formats section. Codexa also takes MS Project schedules and site photos and videos, and issues export to BCF for Revit or Navisworks users.
Who on a project uses Codexa?
Owners, design consultants, supervision consultants and contractors. Each person is given the right role in each feature group, and one person can take on several roles.
Does the Institute help bring Codexa into a project?
Yes. The Institute's BIM office SBIM helps set up the folder structure, file coding convention and approval steps, and trains the project team.
