Interface management software for rail, metro and multi-contract projectsEvery interface under control, from definition to handover
InterfacePass follows each interface between contracts through design, construction, testing and handover, so complex multi-contract projects hold fewer surprises for contractors, clients and lenders.
No card needed. We set the trial up with you on your own project exports.Swipe the map to follow the line.
An invented line, for illustration. Brackets show which contract builds what; each dot is an interface between contracts, coloured by the state of the RFIs raised on it.
Three exports go in, one register comes out
The information already exists. It sits in three systems that don't talk to each other, and in the spreadsheets people keep to bridge them.
See it on a project
These screens come from the product, loaded with an invented project: two civil works contractors, one systems contractor and an engineer.
One interface, three phases to pass
Every interface has to pass each phase: defined and designed, built as agreed, then tested and handed over. InterfacePass keeps one record of it from start to finish.
Answered is not closed
People who track RFIs in project mail systems describe the same three traps in their reviews.
InterfacePass gives every RFI one of five states, and always shows who must act next.
Who it is for
- Interface and integration managers
- Design managers and engineering leads
- Civil works contractors and joint ventures
- Systems and track contractors
- Engineers and project management consultants
- Client and owner teams
- Project directors and package managers
- Technical advisers to lenders
The problems it solves
- Hidden open questions. Answers nobody has accepted sit inside "responded".
- Three versions of the truth. The mail system, the register and each party's spreadsheet disagree.
- Meetings without a record. Actions live in minutes nobody rereads.
- Design built on unsettled interfaces. An ICD is issued while its questions are still open.
- Late surprises at handover. What was agreed on paper was not checked on site.
Definition and designAvailable
Built for the interface meeting. Open one screen, filter by party, contract or design stage, and go down the list. Each RFI says who it is waiting on and for how long.
An RFI that has been answered is not finished. InterfacePass separates answered from closed, so the pile of answers nobody has accepted stops hiding inside "done".
RFIs as threads
Mails are grouped by project reference, typos included. One RFI shows every request and response with its date and organisation.
Interfaces linked to RFIs
Each register entry shows the RFIs raised against it. Suggested links come from similar wording; you confirm each one.
ICD maturity you can defend
Progress per ICD counts closed RFIs only, by design stage, so 95% on paper means 95% settled.
A check list after every import
Unmatched mails, RFIs without a reference, and differences between trackers are listed for you to settle.
Meetings that write their own minutes
Pick the parties attending and the agenda builds itself. Record decisions and actions as you go, then download the minutes in Word.
A progress report in one tap
Slides on RFI and ICD status by design stage, shown in the workspace and downloadable as PowerPoint or PDF.
Your entries survive each import
Upload a fresh export every week. Closures, links, notes and meeting actions you recorded stay in place.
Everything out to Excel
RFIs with their description and latest status, interfaces, ICDs, meetings and actions, one sheet each.
Design stage on every RFI
Filter by 60%, 95% or 100% design, and see which questions still hold up the stage you are about to submit.
ConstructionFirst version
What was agreed in the ICDs has to be built. This phase follows the civil works that track and systems depend on, together with worksite sharing, delivery routes, access and temporary works.
Site requirements per interface
Permanent works, temporary services, access routes and shared worksites, each with a provider, a needed-by date and a status.
Site issues to closure
Non-conformances and snags raised from site, each with an owner, a due date and closure evidence.
Progress along the line
One bar per asset, by chainage, showing what is built, what is verified and what is late. Photo capture and letters come next.
Testing and handoverFirst version
An interface is finished only when it has been tested and the asset has changed hands. This phase shows readiness, test results and handover on one line per asset.
Readiness per asset
Permanent provisions built, temporary services live, access route open and defects closed, checked together before access is given.
Interface tests with evidence
Each interface ends with its integration test result and closure evidence, in the handover sequence from civil works to track and systems.
A record both sides sign off
Each handover keeps its evidence and open reservations, so later claims start from an agreed record.
How it works
Upload your exports
The Aconex mail export, your Excel tracker and the ComplyPro register. File types are recognised on their own, with no column mapping.
Settle what the import found
Go through the check list once: the few mails that could not be matched and the statuses that disagree.
Run the meeting from it
Mark answers, close with an outcome, log actions. Upload a fresh export each week and your own entries are kept.
The pilot programme: five projects
We are opening InterfacePass to five multi-contract projects. It runs as a service first, so your team sees results before anyone learns a new tool.
What you send
- Your mail register export, RFI tracker and interface register
- One contact who knows the interfaces
- A confidentiality agreement, signed both ways
What you get
- Your register loaded and checked within 48 hours
- A first progress report as slides
- The list of answers nobody has closed, and who holds each one
- A 30-minute review call
What we ask
- Your corrections, so the product learns your project
- A debrief after 60 days
- If it helped, a sentence we may quote
Why it exists
Every interface meeting I have run on metro and high-speed rail projects began with the same question: who owes the answer? The information was always there, spread over a mail system, a register and three spreadsheets. InterfacePass puts it on one screen.The founder, interface and integration manager on rail systems projects

Questions people ask first
What is interface management on a multi-contract project?
It is the work of identifying where the scopes of different contractors meet, agreeing who provides what and by when, and following each of those interfaces until it is built, tested and handed over. On a rail project that means, for example, the cable routes, earthing, foundations and equipment rooms that civil works must provide for track and systems.
What is an interface register?
A list of every interface between contracts, each with an identifier, the party who needs it resolved, the party who must provide it, and its status. InterfacePass reads your register and links each interface to the RFIs raised about it.
What is an interface control document, or ICD?
The document two parties sign to record what they have agreed at an interface. ICDs are usually issued at each design stage, for example 60%, 95% and 100%. InterfacePass shows how many ICDs are signed, closed, in progress or not started at each stage.
Why is an answered RFI not a closed RFI?
Because an answer still has to be accepted by the party who asked, and its consequence recorded in the design or the ICD. Until then the work may proceed on the old assumption. InterfacePass keeps the two apart, and does not count a request for clarification as an answer.
Does it replace Aconex or ComplyPro?
No. They remain the official systems. InterfacePass reads their exports and shows what neither shows alone. Nothing is sent back to them.
How long does it take to learn?
It is built to need no training. You upload the exports your project already produces, and the first screen shows what is overdue and who holds it.
Where is our data kept?
Hosting in the EU or the UAE is agreed with you before any project data is loaded. Only organisation names are stored from mail exports, not the names of individual senders.
What if our reference format is different?
Reference patterns are set per project during onboarding. Send a sample export and we confirm the match rate before you commit.
How do we sign in during the pilot?
Pilot workspaces are opened by invitation. Request a trial, and we set up your workspace and send access to the people you name. Self-service accounts come with the hosted release.
