Construction Company: Real-Time Site Dashboard

Construtora Vale do Sado (real case — data altered under NDA), a civil construction company in Leiria with 35 employees and 4 concurrent sites, only discovered that a site was exceeding its budget when it was already too late to correct course. Financial information arrived 3 to 4 weeks late, quantity surveys were done on paper and subcontractors communicated by phone call. After implementing a real-time site dashboard, digital quantity surveys and a subcontractor portal, budget overruns dropped from 18% to 5%, invoicing accelerated by 65% and the company gained the capacity to manage 6 concurrent sites without expanding the office team.

The Scenario Before: Building Without a Map

Civil construction is, historically, one of the sectors most resistant to digitalisation. At Construtora Vale do Sado, a family business with 28 years of operation, processes were the same as when the founder started the company. João, the current manager and the founder's son, knew he needed to change — but did not know where to begin.

The cost control process worked as follows: the site foreman recorded, in a notebook, materials received, labour hours and work completed by subcontractors. At the end of each week, he handed the notebook to Sandra, the accountant, who transcribed the data into an Excel spreadsheet. Sandra consolidated the 4 sites and delivered João a monthly cost report — typically in the second week of the following month.

The problem was obvious: by the time João saw that the residential building site in Marinha Grande was 12% over budget, 6 weeks had already passed since the overrun began. The opportunity to correct — renegotiate a supplier, substitute a material, adjust planning — was lost.

Quantity surveys — the process by which the contractor determines work completed for invoicing to the client — were another bottleneck. The project manager, engineer Rui, visited each site fortnightly, measured works with tape measure and notebook, returned to the office, entered the data into Excel, compared against the original bill of quantities and prepared the interim certificate. This process took 3 to 5 days per site. With 4 sites, Rui spent half the month on surveys and the other half preparing documents — with no time for actual management.

The Numbers Behind the Problem

• Average budget overrun: 18% — nearly one in every five euros spent was unplanned.
• 3–4 weeks delay in financial information per site.
• 3–5 days per survey per site — 12–20 days/month spent on surveys.
• Delayed invoicing: on average 22 days between work completion and invoice issue.
• Communication with subcontractors: exclusively by telephone and WhatsApp — no formal record.
• Maximum capacity: 4 concurrent sites — limited by the team's management capacity, not execution capacity.

The Solution: Site Management Platform

Phase 1 — Site Dashboard (Weeks 1–6)

We developed a dashboard that consolidates, in real time, all financial and operational information for each site. The dashboard has four main panels:

• Financial panel: total budget, accumulated cost, forecast final cost (based on current trend), variance in euros and percentage, and breakdown by chapter (foundations, structure, masonry, finishes, etc.).
• Planning panel: Gantt chart with actual vs. planned progress, critical path and forecast completion date.
• Resources panel: labour present per day (recorded via app on the foreman's phone), equipment on site and materials in transit.
• Quality panel: non-conformance reports, tests carried out and outstanding items to resolve.

Data input is simple: the foreman records daily, via a phone app, materials received (with photo of the delivery note), hours worked by each team and works completed. It takes 15 minutes per day — instead of the weekly hours with notebooks that then had to be transcribed.

João sees, every morning, an automatic email summary: status of each site, variance alerts and outstanding items. Without phoning anyone, without waiting for reports, without surprises.

Phase 2 — Digital Quantity Surveys (Weeks 4–8)

We replaced the manual survey process with an app that allows engineer Rui to carry out surveys directly on site, with a tablet. The app loads the original bill of quantities and allows Rui to mark completed works — by item, quantity and location. He can attach photographs as evidence.

The interim certificate is generated automatically in the format required by the client, with a comparison between contracted and executed quantities. What previously took 3–5 days per site now takes 2–3 hours — including the site visit. Rui went from "half the month on surveys" to "one day per site per month", freeing time for management, coordination and problem resolution.

Invoicing, which depended on surveys, accelerated proportionally. The average time between work execution and invoice issue dropped from 22 days to 8 days — significantly improving the company's cash flow.

Phase 3 — Subcontractor Portal (Weeks 6–10)

The company worked with 12 to 15 subcontractors simultaneously. Communication was by telephone and WhatsApp — no formal record, no traceability, no read confirmation. Misunderstandings were frequent: "I said Tuesday", "No, you said Thursday".

We created a simple web portal where each subcontractor has access to their own space: they see assigned tasks, deadlines, relevant drawings/plans and quantity survey records for their work. When the contractor assigns a task, the subcontractor receives a notification and confirms. All communication is recorded in the portal — replacing informal calls and messages.

The portal also allows subcontractors to submit quantity surveys for their work, which the contractor validates before processing payment. This process, which previously involved face-to-face meetings and paper documents, is now completed digitally within 24 hours.

The Results: Before vs. After

Twelve months after implementation:

• Average budget overrun: from 18% to 5% (−72%). Real-time visibility allows correcting variances while they are still small.
• Financial information delay: from 3–4 weeks to real time.
• Survey time per site: from 3–5 days to 2–3 hours (−90%).
• Invoicing timeline: from 22 days to 8 days (−64%). Significant improvement in cash flow.
• Management capacity: from 4 to 6 concurrent sites without expanding the office team.
• Disputes with subcontractors: 80% reduction — all communication is recorded and traceable.
• Manager's time on reactive management: from 60% to 20% — João shifted to business development instead of "firefighting".

The Financial Impact

The total investment — platform, site app, subcontractor portal, tablets and training — was €19,500. The direct return: reducing budget overruns from 18% to 5% on sites with an average value of €800,000 represents a saving of €104,000 per site. With 5 to 6 sites per year, the annual saving exceeds €500,000. The project's payback occurred before the first site was completed with the new system.

The capacity to manage 6 sites instead of 4, without additional overhead costs, represented a 50% increase in potential turnover — the equivalent of hiring an entire management team, without the associated cost.

Lessons for Other Construction Companies

1. Late information is almost as useless as no information. Knowing that a site exceeded its budget after it is already built is archaeology, not management. Real-time information is what enables proactive management.

2. Digital surveys free engineers for engineering. A site engineer who spends half the month transcribing surveys into Excel is an expensive resource doing administrative work. Digital surveys return the time for what truly matters.

3. The subcontractor portal reduces conflict. When everything is written, documented and accessible, misunderstandings disappear. The relationship with subcontractors improves — and better relationships mean better prices and greater commitment.

Conclusion

Civil construction does not need cutting-edge technology to digitise. It needs simple, affordable tools adapted to the reality of construction sites — where dust, rain and dirty hands are the norm. Construtora Vale do Sado proved that with a dashboard, digital surveys and a subcontractor portal, it is possible to radically transform how a site is managed. The result was not merely financial — it was a cultural shift, where decisions came to be based on data rather than intuition.
