EIR, BEP, MIDP and TIDP Explained: The ISO 19650 Information Delivery Chain for Pune BIM Managers

Ask a roomful of Pune BIM engineers what an EIR, a BEP, an MIDP and a TIDP are, and most will give you a vague answer. These four acronyms sit at the heart of ISO 19650, the international standard for managing information on BIM projects, and they are exactly what separates someone who can model from someone who can manage a project's information. If you want to move from coordinator to BIM manager in Pune, this is the chain you must understand.

The good news: the framework is far simpler than the jargon makes it sound. Think of it as a conversation between a client and a delivery team, written down properly.

EIR — the client asks the question

Everything starts with the Exchange Information Requirements (EIR). This is the client's document. It states what information they need from the project, in what format, to what level of detail, and at which milestones — and, crucially, why they need it. A developer might need accurate room data for facilities management; a public authority might need asset information for maintenance. The EIR turns those needs into clear requirements before any modelling begins.

If you have read our guide to the ISO 19650 standard for Indian engineers, the EIR is where that standard becomes practical: it is the trigger for the whole information process.

BEP — the delivery team answers

The BIM Execution Plan (BEP) is the delivery team's response to the EIR. Where the EIR asks, the BEP answers: here is how we will meet your requirements, here are the standards and software we will use, here is our common data environment, here is the federation strategy, and here are the people responsible. A BEP is produced at tender stage (the pre-appointment BEP, a pitch) and then confirmed and detailed after the team is appointed.

Many Pune engineers first meet the BEP on its own and assume it is the whole story. It is not — it is one half of a question-and-answer pair. Our dedicated guide on what a BEP contains goes deeper on its structure.

TIDP — each task team commits to a plan

Once the team knows what it must deliver, the work is broken down. Each task team — the architects, the structural engineers, the MEP team — produces a Task Information Delivery Plan (TIDP). The TIDP is simply a list: which information containers (models, drawings, schedules, documents) that team will deliver, who is responsible, and the dates each is due. It connects deliverables to people and to the programme.

MIDP — the master plan that ties it together

Individually, the TIDPs are useful but fragmented. The Master Information Delivery Plan (MIDP) combines every task team's TIDP into one master schedule of information for the entire project. It is the single document that tells the lead appointed party — and the client — exactly what information is being delivered, by whom, and when, across the whole job. The MIDP is what a BIM manager lives by.

The chain in one sentence

Put simply: the client writes the EIR (what we need), the delivery team responds with the BEP (how we will deliver it), each task team writes its TIDP (what I will deliver and when), and all the TIDPs roll up into the MIDP (the master delivery programme). Underpinning all of it is the Common Data Environment (CDE), where every information container is shared, checked and approved with proper status codes.

Why this matters for a Pune career

Modelling skills get you into BIM. Understanding the information delivery chain is what gets you promoted. As Pune becomes a delivery hub for UK, Middle East and Australian projects — all of which mandate ISO 19650 — firms desperately need people who can write a BEP, build a TIDP, assemble an MIDP and run a CDE. Those are BIM manager and information manager roles, and they pay accordingly. An engineer who can speak this language fluently is far more than a modeller; they are someone a firm can put in front of an international client.

Learning it the practical way

These documents are best learned by producing them, not memorising definitions. At ABC Trainings in Pune we take engineers through a realistic scenario — a client EIR, a team BEP in response, task-team TIDPs and a consolidated MIDP — so the chain stops being four confusing acronyms and becomes a workflow you can actually run on a project.

Frequently asked questions

What is the difference between an EIR and a BEP?

The EIR (Exchange Information Requirements) is written by the client and says what information they need and why. The BEP (BIM Execution Plan) is the delivery team's answer, explaining how they will meet those requirements. EIR is the question; BEP is the response.

What do MIDP and TIDP mean?

The TIDP (Task Information Delivery Plan) lists what each task team will deliver and when. The MIDP (Master Information Delivery Plan) combines all the TIDPs into one master programme of information deliverables for the whole project.

Do Pune projects really use ISO 19650?

International projects delivered from Pune almost always do, and Indian public and private clients are adopting it gradually. Even where it is not contractually required, understanding the framework makes an engineer far more employable with global AEC firms.

Do I need to be a BIM manager to learn this?

No, but it is essential for anyone who wants to become one. Even modellers and coordinators benefit from understanding where their deliverables sit in the information chain, because it explains why naming, status codes and the CDE matter.
