How to Create a Manufacturing Data Book | Step-by-Step MDB Workflow

STEP 01

Define the document index

Start with a structured index that lists every chapter the MDB must contain. The exact list depends on your contract and applicable codes (ASME, PED, EN 1090, NORSOK), but a typical pressure-vessel or skid MDB has 8 to 12 main chapters: project information, materials, welding, NDT, dimensional inspection, pressure / leak test, drawings, certificates, and as-built documentation. Each chapter needs sub-sections, owners and revision status. Without a clear index up front, every document review later becomes a search.

STEP 02

Assign chapter owners

An MDB is a multi-author document. Welding records come from the welding engineer, NDT reports from the inspection company, MTRs from the material supplier, drawings from engineering. Assigning each chapter or sub-chapter to a named owner — internal team member or external supplier — turns the MDB from a single person's burden into a coordinated workflow. This is also the moment where you decide which chapters will be filled by suppliers and what evidence each supplier needs to deliver.

STEP 03

Collect documents and track delivery

Each chapter owner uploads the required PDFs as the project progresses. The hardest part is tracking what has been delivered, what is missing, and which version is current. Quality teams traditionally do this with an Excel tracker plus shared folders. The result is well-known: lost emails, conflicting versions, WeTransfer links that expired, and the document controller spending the last week of the project chasing missing files.

STEP 04

Manage revisions: IFR, IFA, Approved

Engineering documents move through a formal revision workflow: Issued for Review (IFR), Issued for Approval (IFA) and finally Approved. Each transition is a transmittal — a formal hand-over with a document list, revision numbers and a date. In a manual workflow this is a separate Excel sheet. In a purpose-built MDB platform every upload is automatically tagged with revision status and the transmittal is generated from the live document list, with no double bookkeeping.

STEP 05

Compile the final bookmarked PDF

Once every chapter is complete and approved, the documents need to be assembled into one final delivery PDF. That PDF must contain a cover page with project metadata, a clickable table of contents, bookmarks for every chapter and sub-chapter, and consistent page numbering. Doing this manually with Adobe Acrobat or a PDF merger for a 300- to 1,500-page MDB typically takes several hours per project — often four to sixteen, depending on document count and revision frequency — and the work is repeated for every minor revision.

STEP 06

Submit for client review and approval

The final MDB goes to the client for formal approval. Traditional workflows use email and WeTransfer, with comments returned by markup or in a separate Excel sheet. A modern workflow gives the client a secure online link, lets them comment in-context per chapter and returns a formal approval signal that closes the project — and unlocks the final payment milestone.

The MDB Builder by BizzBit replaces the Excel tracker, the Adobe Acrobat assembly job and the WeTransfer chase — in one tool. It generates the structure in three minutes, tracks supplier deliveries in real time, and compiles the final bookmarked PDF for you. Launching Q3 2026. Join the waitlist for free early access.

Frequently asked questions.

How long does it take to create a Manufacturing Data Book?

It depends on project size and how the workflow is set up. Building the structure is typically a one-day exercise. Collecting certificates and reports happens over the lifetime of the project, in parallel with manufacturing. Compiling the final bookmarked PDF and getting client approval traditionally takes between one and three weeks for a typical mid-size project — most of that time is spent chasing missing documents and rebuilding the PDF after every revision. With a purpose-built MDB platform, the structure and final PDF assembly drop to minutes.

Who is responsible for creating the MDB?

Responsibility usually sits with the Quality Manager or Document Controller of the manufacturing or fabrication contractor. On larger EPC projects there is often a dedicated MDB Coordinator. The actual content comes from many roles — welders, inspectors, designers, suppliers — but a single owner is needed to coordinate and to deliver one consistent document to the client.

What documents go into a Manufacturing Data Book?

The exact list depends on the contract and applicable codes. A typical MDB contains: project information and scope, material certificates (MTRs / EN 10204 3.1), welding documentation (WPS, PQR, welder qualifications, weld maps), non-destructive testing reports (RT, UT, MT, PT, VT), dimensional inspection records, pressure or leak test reports, drawings (engineering and as-built), heat treatment records, calibration certificates, surface treatment and painting records, and a Declaration of Conformity or Certificate of Compliance.

Can a supplier upload directly into the Manufacturing Data Book?

Yes — but only if the workflow supports it. In a manual Excel-and-WeTransfer workflow, suppliers email PDFs and the document controller manually files them. In a purpose-built MDB platform, the supplier receives a secure link to upload the chapters they own. They do not need an account. The platform records exactly what was delivered, when, and by whom, and the receiving team monitors progress and approves or rejects in real time.

What is the difference between an MDB and a transmittal?

A Manufacturing Data Book is the complete quality documentation package handed over at the end of a project. A transmittal is a formal cover note that accompanies the delivery of one or more documents at any stage of the project — for example, sending a batch of welding documents for client review during fabrication. The MDB is the destination; transmittals are the steps along the way.
