What must a public tender ERP for construction include?

Non-negotiable minimums: native import and export of structured BoQ (Bill of Quantities) data, tender specification and deadline management, supplier RFQ workflow with comparatives, multi-scenario bid studies, bond and guarantee control, HSE and corporate compliance documentation, progress billing aligned with contractual schedules, and full traceability from estimate to award. dvproject Construction covers these points on top of Business Central.

What is the BC3 (BoQ) format and why is it critical?

BC3 (FIEBDC-3) is the standard exchange format for measurements and budgets in Spanish construction, equivalent to a structured BoQ. Public authorities require it in most tender packages. Any ERP serving the tender market must import and export BC3 without data loss, preserving 7 levels of chapters, breakdowns and work units. dvproject Construction supports BC3 natively, both to import tender documents and to export bids — and equivalent BoQ workflows for international projects.

How much can a specialist ERP save in the tender process?

Average bid preparation time for a mid-sized public works project (€3–15M) drops from 80–120 hours (estimating software + Excel + email) to 30–50 hours with an integrated ERP like dvproject Construction. Over 20 tenders a year that is ~1,000–1,500 hours saved — equivalent to one full estimating engineer. And, above all, bid quality improves: more rigorous supplier comparatives, fewer arithmetic errors, better risk control.

How does dvproject manage bonds and guarantees?

Every public tender has its own bond schedule: bid bond (at submission), performance bond (at award), additional bonds. dvproject Construction maintains the bond portfolio with amount, issuing bank, issue date, expiry and status (active, returned, called). Automatic alerts before expiry. Without this, contractors pay unnecessary bank fees on bonds that should already have been released.

Is it only for public tenders or also for private work?

Both. dvproject Construction manages the full project cycle (estimate → award → execution → progress billing → closeout) for public and private work alike. The operational difference comes from the client: public work demands structured BoQ exchange, rigid billing calendars, bond management and compliance documentation; private work is usually more flexible. dvproject supports both models in the same installation.

How does Business Central fit a small-to-medium contractor?

Business Central is Microsoft's ERP for SMEs (typically 10–250 employees). dvproject Construction plugs in on top as a vertical extension. The SME contractor gets in a single system: financials (with its usual accountant), treasury, procurement, sales and everything specific to construction. Davisa, Microsoft partner since 2003, deploys the suite scaled to the company's size and maturity.

dvproject Construction — ERP for construction companies in public tendering

Construction companies that live off public tenders (government bodies, public agencies, large prime contracts) operate at a different intensity. Every tender package is a project in itself — weeks of estimating, dozens of BoQ sheets, supplier RFQs, contractual scoring grids, bank bonds. And all of that to submit a bid that is won or lost by a decimal point.

A generic ERP will not cut it in this scenario. You need a system that speaks the language of the sector: BoQ structures, chapters, breakdowns, progress billing, bonds, retention. This article explains what a construction ERP for public tendering must offer, and why dvproject Construction on top of Microsoft Dynamics 365 Business Central is the answer Davisa has been deploying for more than two decades.

Context disclosure: Davisa has been a Microsoft Business Central partner since 2003 and develops dvproject. This article aims to be honest about what a public tender requires and where dvproject adds value — it is not a neutral comparison, but the criteria are.

The 7 capabilities a tender management ERP must have

1. Native BoQ import and export

The BC3 (FIEBDC-3) format is the sector’s exchange standard in Spain, and equivalent structured BoQ exchange (CSV, XML, IFC) is the norm internationally. Without native BoQ handling, you are not in the game. The ERP must:

Import the tender BoQ without data loss (7 levels of chapters, breakdowns, quantities, prices).
Allow the budget to be edited while keeping the structure.
Export the bid BoQ for submission.
Support format variations by authority (some require their own extensions).

2. Bid studies with multiple scenarios

A serious tender never has a single bid — it has scenarios: aggressive commercial offer, balanced technical offer, controlled abnormally-low offer. The ERP must let you keep several versions of the same study, compare them and archive the one submitted.

dvproject Construction manages unlimited versions of the study per project, with version comparison and BoQ export of the chosen one.

3. Supplier RFQ workflow

Before closing the bid price, you have to request prices from real suppliers and subcontractors (not estimate them). The ERP must let you launch bulk RFQs straight from the bid study, register responses and consolidate them in the comparative (see procurement comparatives).

4. Indirect cost and bid discount calculation

Contracting authorities publish discount scales and abnormally-low-bid mechanisms. The ERP must compute:

Direct cost by chapter.
Allocated indirect costs (overheads + industrial margin).
Bid price vs. tender price (discount %).
Alert if the discount enters the abnormally-low band per the tender rules.

5. Bond and guarantee control

Every public tender carries at least one bid bond (usually around 5% of the base budget) and, if awarded, a performance bond. dvproject keeps:

Full bond portfolio (bid bond, performance bond, additional bonds).
Amount, issuing bank, issue date, expiry.
Automatic alerts before expiry → claim back from the bank.
Return recorded when the client releases it.

Without this, contractors pay unnecessary bank fees on bonds that should already have been released.

6. Contractual progress billing

In public works, progress billings are monthly and rigid: cut-off date, project management approval deadline, payment deadline. The ERP must generate cumulative progress billings automatically from measurements and respect the contractual calendar.

dvproject Construction generates cumulative and net progress billings in one click — see progress billing in Business Central for the full workflow.

7. Up-to-date corporate and HSE documentation

Public works demand constant documentation: up-to-date tax and Social Security clearance certificates, valid liability insurance, health & safety plan, HSE training for site personnel. The ERP must manage this documentation with:

Expiry dates and automatic alerts.
Linkage to the resource (worker) and to the project.
Traceability for spot audits.

Why Business Central as the platform

Business Central is Microsoft’s ERP for SMEs. It brings to a contractor:

Standard financials, treasury, procurement, sales (compliant with local e-invoicing requirements).
Multi-company, multi-currency, multi-language if it grows internationally.
Native integration with Microsoft 365 (Excel, Teams, Outlook, SharePoint).
Continuous half-yearly updates guaranteed by Microsoft.
AL extension ecosystem — verticals like dvproject Construction plug in without touching the core.

The typical SME contractor that reaches Davisa moves from 4–6 disconnected tools (standalone estimating software + generic ERP + master Excel files + email-based CRM) to Business Central + dvproject Construction as a single backbone.

Commercial model — no surprises

dvproject Construction is offered as an annual licence plus implementation quoted to scope. Davisa tailors the scope to the size and maturity of the company: a contractor with 8 people and 4 concurrent projects does not need the same rollout as a group with 200 people and 30 projects.

To see a concrete proposal with your own data, the most efficient path is a diagnostic session — 30–45 minutes in which Davisa understands your project model and comes back with a proposal covering scope, timeline and firm price.

Closing — the ERP that understands the sector

Public tendering does not forgive generic tools. Every tender package is a complex commercial project that demands structured BoQ exchange, supplier comparatives, bonds, progress billing and current compliance documentation. An ERP that does not speak that language generates permanent friction — and, in too many cases, worse-calculated bids and worse-controlled projects.

dvproject Construction on Business Central has been Davisa’s bet for tender-driven construction companies for more than two decades. The reason is that it is built from the sector, for the sector — it is not a generic ERP with a construction module bolted on.
