Prepare a monthly client report with AI in project management

The monthly report of project management consists for the most part of material you already have: meeting minutes, programme, cost status, correspondence. With AI, a draft can be prepared from this that pulls together dates, costs and open points. What the situation means and what you recommend to the client is written by the project lead.

Reporting in project management

The AHO publication series, issue 9 (“Projektmanagement in der Bau- und Immobilienwirtschaft, Standards für Leistungen und Vergütung”), describes the service profile of project management. The publisher is the AHO, the German committee of engineers’ and architects’ associations and chambers on fee matters. According to its press release on the 2020 edition (as at March 2020), the profile has five fields of action: (A) organisation, information, coordination and documentation, (B) quality and quantities, (C) costs and financing, (D) dates, capacities and logistics, and (E) contracts and insurance.

The AHO now lists the issue on its website as at May 2025. A software vendor calls the 2025 edition the sixth edition in a blog post and describes the same five fields of action. That is a secondary source. According to the AHO website the publication costs 48.80 euros and I do not have it, so I have not checked the new edition against the original. I therefore mention the issue only as a reference and do not reproduce any further content.

How often you report and what the report must contain is governed by your contract. The structure along costs, dates, quality and contracts roughly matches the fields of the 2020 edition. Your client may ask for a different structure.

Structure of a monthly report

I propose this structure, which follows no standard: a summary for the client with status and need for decision, then the chapters Dates, Costs, Quality, and Contracts and variations, followed by the list of open decisions and the appendices. The chapters can be prepared from sources. The project lead writes the summary last, because it does more than summarise: it sets priorities.

1. SourcesMinutes, programme, cost status, correspondence, frozen at the cut-off date
2. Draft (AI)Structure, text and tables, every figure with source and status
3. Assessment (you)Judgement, recommendation and signature of the project lead

• Layer 2 from the bottom: Draft (AI), Structure, text and tables, every figure with source and status
• Layer 3 from the bottom: Assessment (you), Judgement, recommendation and signature of the project lead

The sources

Every statement in the report should point to something that already exists. The table assigns chapter, source and division of tasks:

Chapter	Source	The AI prepares	Stays with you
Dates	Programme, minutes	Compile deviations and stated causes	Assess the effect on the handover date
Costs	Cost status, checked invoices, variations	Fill the table, describe the development	Assess the forecast and reserves
Contracts	Correspondence, instructions, notices of hindrance	List with date and status	Position and recommendation
Open points	Minutes	Open decisions with the persons responsible	Weighting, what the client must decide

How a meeting becomes minutes that work as a source is described in Meeting minutes with AI: from recording to sign-off.

Set a cut-off date on which the sources are frozen for the report, and state it in the report. Otherwise the draft contains Monday’s programme next to Friday’s cost status.

The HOAI (German fee regulations for architects and engineers) also lists programme, cost control and cost determination as basic services of site supervision in work stage 8 (Annex 10 no. 10.1, letters d, i and j, for buildings and interiors, in the version as at November 2026). So the building blocks of a report arise at points where documentation takes place anyway. The better the minutes and the cost status are maintained, the less has to be researched again for the report.

The draft

The AI reads the sources, assigns them to the chapters, summarises them and writes paragraphs in your template. It can fill tables with programme deviations and open points. An example with invented data:

The programme (as at 28 February) shows a deviation of two weeks against the baseline programme for the shell construction. Cause according to the minutes of 12 February: delayed delivery of the precast elements.

The sentence names source, status and cause. It does not say whether the handover date is at risk.

Figures only from checked sources

A language model produces text and does not calculate reliably, and it can produce values that sound plausible and are wrong. In its guidance on AI applications involving personal data, the Data Protection Conference (DSK) notes that providers of language models often state themselves that their texts make no claim to accuracy and should always be questioned. For the report this means: the software copies figures from the source file into the table, and the model writes only the text around them. Every figure carries a source and a status, as described for AI answers in general in Why AI answers need a source reference. A cost status that nobody has checked yet is marked as provisional in the report, or not used at all.

Before sending, you reconcile. A spot check is not enough if a figure has consequences: check every figure that the client uses for a decision against its source. The person who writes the report should not be the only one to check. A second person compares the figures with the sources, because your own text reads too smoothly.

A fixed template also helps the client. If dates, costs and open decisions are in the same place every month, changes are easier to spot. The draft must therefore always deliver the same chapters in the same order, even if a chapter occasionally contains only “no change”.

Checking steps before sending

The draft goes to the client only after these steps. The order is my suggestion:

1. Cut-off date and status of the sources: does the same status apply to all chapters, and is it stated in the report?
2. Figures: every figure that the client uses for a decision is checked against the source by a second person.
3. Statements without a source: a sentence for which no source can be named is deleted or substantiated by the project lead.
4. Consistency: does the summary match the chapters, for example on the date and on the cost status?
5. Assessment and recommendation: the project lead writes both and signs.

How much time the draft saves

A monthly report in project management takes about 5 hours today. That is a figure from the author’s practice in project management and has not been measured. For the saving, the range that this website uses for reports and draft texts applies: 16 to 28 per cent. It covers only gathering the material and the draft. Checking and release stay with you.

The calculation: 5 hours are 300 minutes. 16 per cent of that is 48 minutes, 28 per cent is 84 minutes. A report then no longer takes 5 hours but 4.2 to 3.6 hours. The shorter figure of 2 hours per text in this website’s calculator stands for shorter reports and draft texts; a project management monthly report takes longer.

Testing a draft

The simplest test uses your last report. Assemble the sources from the cut-off date at the time, have a draft produced and lay it next to your report. Then check where the draft deviates: are points missing? Do figures differ? Has the AI added something that is in no source? Every deviation shows where the template, the sources or the checking rule need improving. As a rule of thumb that I cannot substantiate: only when three reports in a row run through cleanly is it worth using it in a live project.

What stays with you

The assessment is the core of the report. Whether a deviation is a problem, how seriously to take a variation, which measure you propose and what the client needs to know first depends on the project, the contract and the relationship. An AI knows none of that. You also decide the tone in case of delay or dispute.

A sentence that only you can write (example with invented data): “The deviation in the shell construction does not endanger the handover date as long as the precast elements are delivered by the end of March. We recommend having the delivery commitment confirmed in writing.” It contains a judgement and a recommendation. Both presuppose that someone knows the supplier, the construction time and the contract.

The Federal Chamber of Engineers (Bundesingenieurkammer) writes on the use of AI: “When AI tools are used, it is always engineers who in the end take personal responsibility” (my translation). The sentence refers to AI-based services in engineering in general. In spirit it carries over to the monthly report, because the report goes out under your name.

Project data belongs on platforms that can be operated in line with the GDPR, that is in the EU or locally and with a data processing agreement. What matters in that agreement is covered in Data processing agreements for AI services: what to check. Consumer chat services are not a route for project data. Also check whether your contract with the client restricts passing on project documents. Your lawyer clarifies that, and your data protection officer clarifies the data protection questions.

What you can do now

1. Mark every paragraph of your last report: source or assessment? The share shows what can be prepared.
2. Decide which sources, with which status, may go into the report, and who releases them.
3. Build a fixed template with unchanging chapters. Without one, every draft turns out different.
4. Write down a checking rule for figures: which figure is reconciled against which source, and by whom?
