Frequently asked questions
Thursday, 2 p.m.: A civil engineering contractor sends the complete bill of quantities (BoQ) for a sewer rehabilitation with 380 line items and asks for material prices by Monday, because the bid deadline is Tuesday. Perhaps 120 of the line items are material; the rest are earthworks, dewatering and surfaces. In civil engineering supply, exactly this task decides the order: spotting material line items quickly, matching them correctly and pricing them in time. AI can take over most of this preparatory work, and inside sales reviews and approves.
Key takeaways
Civil engineering distributors often receive complete construction BoQs in which material and labor are mixed; the material is frequently hidden in the long text ("supply and install").
The time pressure comes from the customer's bid deadline: whoever answers too late is not considered in the customer's calculation.
Many line items need project prices from the manufacturer, such as manhole structures, road gullies or larger pipe quantities.
AI software like Mercura reads GAEB and PDF BoQs, separates material from labor, matches line items to the range and creates manufacturer price requests.
At the civil engineering specialist distributor Muffenrohr, 100% of requests are processed with Mercura, up to 60% faster.
What is civil engineering supply and what does it deliver?
Civil engineering supply is the specialist wholesale trade for material installed below or on the ground surface: sewer pipes and manholes for drainage, pipes and valves for water and gas supply, cable protection for power and telecommunications, as well as drainage and surface material in road construction. Customers are mainly civil engineering and pipeline construction companies, utilities and municipalities. Many distributors cover the entire civil engineering segment with a broad range, often including bulk materials such as gravel, crushed stone and chippings as well as products for road and path construction such as curbs and paving.
For comparison: civil engineering covers all structures at or below ground level, such as sewers, pipelines, roads and foundations. Civil engineering building materials are accordingly heavy, bulky and often project-specific. The civil engineering specialist distributor Muffenrohr, for example, divides its range into supply, drainage, surface and steel and stainless steel, and according to its own information is present at 47 locations (muffenrohr.de).
How does a request arrive at a civil engineering distributor?
A typical request in civil engineering supply starts with a public tender: an engineering office creates a BoQ on behalf of a municipality or a utility, civil engineering contractors calculate their bid and ask one or more distributors for material prices. The BoQ arrives as a GAEB file, as a PDF or as an Excel excerpt, often complete and not only with the material line items.
Three peculiarities follow from this:
The deadline belongs to the customer. The civil engineering contractor has a fixed bid deadline. The distributor must deliver before it, otherwise the customer calculates with a different price.
Many distributors, one order. Construction companies often ask in parallel. Whoever answers faster and more completely has better chances.
After the award come call-offs. If the customer wins the tender, the material is called off to the construction site in partial deliveries over weeks or months.
Why does a civil engineering BoQ take so long in inside sales?
A civil engineering BoQ takes long because inside sales first has to separate material from pure labor, then read the material specifications from the long text and finally get project prices from the manufacturer for structures without stock articles. Every one of these stages is manual work, and all of them must be done before the customer's bid deadline.
Line item type | Example from a sewer BoQ | What the distributor has to do | Can AI automate it |
|---|---|---|---|
Pure labor | Excavate pipe trench, dewatering | Recognize and sort out | Yes, the relevance filter flags line items outside your range |
Material with labor | Sewer pipe PP DN 300 SN 10 "supply and install" | Read material from the long text, match article | Yes, matching including long text |
Fittings and accessories | Elbows, branches, transitions, sealing rings | Hit the right dimension and system | Yes, with a check against product data |
Structures | Precast manhole DN 1000 with channel, cone, cover class D 400 | Clarify configuration, request manufacturer price | Partly: price request is created, reply is read back |
Optional and as-needed items | House connection with tapping saddle, only if needed | Mark, price separately | Yes, the marking is preserved |
How a BoQ is structured is described in Bill of quantities (BoQ).
What has AI achieved in civil engineering supply so far?
At the civil engineering specialist distributor Muffenrohr, with 650 employees and more than $92 million in revenue, 100% of incoming requests are processed with Mercura, and processing is up to 60% faster. Mario Hinz, Managing Director of Muffenrohr, says: "This AI will change Muffenrohr."
According to the case study, the requests at Muffenrohr consist of many line items from different product categories that have to be checked, matched to the right products and put together into a complete quote. The software takes over this preparatory work, and the sales team gains time for customer advice. The full story: Muffenrohr success story.
Where does AI have limits in civil engineering supply?
AI has limits in civil engineering supply with special structures, with project prices that still have to be negotiated and with technical questions that belong in planning. It prepares, but it decides neither on conditions nor on the suitability of a system for a specific construction project.
Special structures: Stormwater retention basins, pumping stations or custom-made manholes need coordination with the manufacturer and the planner. The software can create the request, not resolve the design.
Project conditions: Whether a manufacturer gives a special price for a project is a matter of negotiation. The software reads replies back but does not negotiate.
Incomplete BoQs: If details such as load class or material are missing, the line item is flagged. Inside sales makes the assumption.
Little BoQ business: Those who mostly do stock sales at the counter and have few project requests benefit less.
How does a civil engineering distributor get started?
A civil engineering distributor starts with a technical test on its own BoQs and its own item master, usually within two working days; first workflows typically go live in less than four weeks. No upfront training is needed, and incomplete product data is supplemented by data sheets and catalog texts.
The ERP remains the leading system, including pricing. Connected systems include SAP S/4HANA, SAP ECC, SAP Business One, Microsoft Dynamics 365, Salesforce, proALPHA and UniTrade, among others, and other systems via an API or SFTP (Integrations). GAEB, PDF, Excel, scans and emails are read. Mercura is certified to ISO/IEC 27001 and hosts in Europe. More under Quotes and tenders and Solutions for distributors.

Conclusion
In civil engineering supply, whoever delivers a complete, correctly priced material quote before the customer's bid deadline wins. The effort lies in separating material from labor, in reading the long texts and in the manufacturer price requests for structures. These are exactly the steps that AI can largely prepare, while conditions and approval stay with inside sales. Muffenrohr shows that all incoming requests can be processed this way.

Frequently asked questions
What is civil engineering supply? Civil engineering supply is a specialist wholesale trade for sewer, supply, cable protection and drainage material. It mainly supplies civil engineering and pipeline construction companies, utilities and municipalities.
What does civil engineering include? Civil engineering includes structures at or below ground level, such as sewer systems, water and gas pipelines, cable routes, roads and foundations. Civil engineering supply delivers the material for these trades.
Can AI read GAEB files from civil engineering tenders? Yes, GAEB files are read, the line items including long texts are matched to the range, and the result can be exported as GAEB or PDF. The format is explained in the article The GAEB format explained.
Does AI recognize which BoQ line items are pure labor? Yes. A relevance filter flags line items outside your range, such as earthworks or dewatering. Your team reviews the selection. If material is hidden in the long text of a labor line item, it is read out and matched.
How does AI handle manholes and structures that are not in stock? For such line items, the software creates a price request to the manufacturer and reads its reply back. Inside sales still clarifies the configuration of the structure with the manufacturer.
How quickly can you test with your own civil engineering BoQs? A technical test on your own data is usually possible within two working days. First workflows typically go live in less than four weeks.
