# AI Solutions for Construction & Job Sites | Alher Tech > PPE detection, accident prevention, progress monitoring, subcontractor docs. Self-hosted AI infrastructure and bilingual support. - Canonical page: https://alhertech.com/en/services/ai-for-construction/ - Site: Alher Tech (custom software, AI agents and SEO engineering, https://alhertech.com/) - Contact: https://alhertech.com/en/contact/ --- AI for construction, pPE cameras, fall detection, restricted-zone alerts and subcontractor document OCR. Edge-only, so no footage leaves the site. ## What AI for Construction Can Do for Your Business - **PPE Compliance Detection**: A typical site deployment, edge-compute cameras at every access point and critical zone, trained to detect missing PPE (helmets, vests, harnesses, gloves), unauthorised entries to exclusion zones, near-misses with heavy machinery and falls. Events push instantly to the site manager's WhatsApp or Slack. Paired with document AI that ingests subcontractor certificates, risk assessments and delivery notes into your construction management tool. - **Exclusion-Zone & Fall Detection**: AI detects workers entering zones under crane load, excavation pits or elevator shafts, plus automatic fall detection that dispatches emergency alerts. - **Progress Monitoring**: Weekly drone or fixed-camera snapshots compared automatically against the BIM plan to measure progress and flag delays. - **Subcontractor Doc Automation**: AI reads the mountain of certificates, risk assessments, delivery notes and invoices that land in your office and extracts structured data into your system of record. - **100% Edge, nothing Leaves the Site**: Inference runs on a rugged Jetson or small GPU server in the site office. Only anonymised event metadata and still images of violations leave the site. - **Alerts in Any Language**: Our bilingual team ships English and Spanish content natively. Your AI agent speaks your customers' language without awkward translations. - **Site Cost Control**: Delivery notes, hours and machinery invoices assigned to the right cost centre, so the deviation against budget shows up weekly, not at the end. - **Progress Billing and Subcontractor Certificates**: Monthly certificates prepared from measured progress, and subcontractor invoices checked against what was actually certified. - **Site Payroll and Safety Records**: Clock-ins per site turned into payroll hours, with training and PPE records kept current for the inspection you did not know was coming. - **Margin per Project**: Certified progress against real costs, so a project that is drifting shows up while there is still time to react. - **Material and Plant Tracking**: Deliveries, stockpiles and machinery on site read from the same cameras, so what arrived and what is idle stops being a phone call. - **Your Own Chat, Not Only WhatsApp**: WhatsApp is one channel, not the plan. We build real-time chat straight into your own website or app, as we did for Boathous and ReservPark, and connect Instagram, web chat, email or the phone line to the same assistant, so the conversation lives where your customers already are. - **Fits the Tools You Already Run**: We plug into the software you already work with instead of asking you to migrate, your booking system, your ERP, your accounting, your spreadsheets if that is what you have. And when the piece you need does not exist in any product on the market, we build it to measure, because that is what we do the rest of the week. - **Prevention Beyond the Helmet**: Working at height without a harness, someone inside the radius of a moving machine, an unprotected edge, a blocked exit or a trench with no shoring. The camera watches for the situations that actually cause serious accidents, not just for the hard hat. - **Warning in the Moment, Not in the Report**: The site manager gets the alert on the phone while there is still time to stop the work. A weekly report that says what happened on Tuesday prevents nothing, so the point is the seconds, not the statistics. - **The Paper Trail an Inspection Asks For**: Our bilingual team ships English and Spanish content natively. Your AI agent speaks your customers' language without awkward translations. ## How We Build Your AI for Construction - **Site Walkthrough**: We visit the site in your business, identify critical zones and optimal camera placements. - **Camera & Edge Install**: PoE cameras and one Jetson edge device in the site office (no cloud required). - **Detection Training**: We train on your exact PPE standards and site-specific exclusion zones with labeled footage. - **Alert Channels**: WhatsApp group for the site manager, email digest for PRL, dashboard for HQ. - **Document Pipeline**: OCR + LLM pipeline that ingests subcontractor paperwork into your construction management software. - **PRL Reports**: Monthly PRL-compliant reports generated automatically with evidence snapshots. ## AI Technologies We Use From self-hosted open-source models to cloud APIs, we choose the right tool for each ai for construction use case. ## Related services Neighbouring problems we also solve, in case the one that brought you here is not the first to tackle. - [Computer Vision](https://alhertech.com/en/services/ai-computer-vision/) - [AI Task Automation](https://alhertech.com/en/services/ai-task-automation/) - [Custom Software Development](https://alhertech.com/en/services/custom-software-development/) - [All our services](https://alhertech.com/en/services/): The full catalogue, from web and mobile to AI, data and maintenance. ## AI for Construction: FAQ ### How do cameras cope with dust, rain and low light? We deploy IP66-rated cameras with IR for night, and the detection model is trained on real site footage including adverse conditions. Accuracy on PPE stays above 92% in normal conditions and drops only marginally at dawn/dusk. ### Is it compliant with data protection for workers? Yes. We avoid face recognition entirely. Detections operate at the level of 'worker on zone X without helmet', never 'worker John Doe'. We provide signage, DPIA support and consult with your PRL and DPO before deployment. ### Can it integrate with my construction management software? Yes, any construction-management tool with an API or email export. Our preferred setup is a custom-coded dashboard for the site manager hosted on your cloud (AWS, Azure or GCP) with alerts piped into Slack or WhatsApp. If you already run a specific tool we connect, but the core logic stays in your code. ### Can the cameras also detect theft after hours? Yes, off-hours activity detection is an easy add-on once the infrastructure is in place. Alerts go straight to the site manager's phone and optionally to security companies. ### How much does it cost? It depends on how many cameras and edge devices the site needs and whether you add progress monitoring and document automation on top of PPE detection. We always audit the site first, and the audit is what produces the number. ### Do you work with businesses across Spain and internationally remotely? Yes. We work fully remotely with clients across Spain, Europe, the US and LATAM. We run video calls, live demos and collaborative documentation for every milestone, and we're available in your time zone.
