Four construction-site examples from real mandates

    High-rise Erfurt-South, 7-day night watch

    12 h × 30 days × €30

    approx. €10,800 / month

    A4 civil engineering, hybrid (personnel + 2 towers)

    10 h × 30 × €28 + 2 × €1,000 tower

Cost drivers

Four factors determine the construction price

  1. 01

    Construction phase and guarding period

    Shell-construction phases with high-value materials (copper, steel beams, tools) are theft-prone — typical guarding duration 2–8 months. Interior work often carries lower theft risk but vandalism concerns. We tier staffing strength and shift model by phase.

  2. 02

    Stationary vs. mobile patrol

    Stationary night watch (one person fixed on-site) costs more per hour than mobile patrol (one car services 4–8 sites per night) but is safer in acute theft phases. Mobile patrol from €280 per night per site, stationary from €1,500 per night.

  3. 03

    Tech integration with video towers

    Mobile AI video towers (autonomous, solar-powered or battery) detect persons and stream live video to our 24/7 monitoring centre. They replace 40–60% of personnel hours and on large outdoor areas (>1 ha) are typically more economical than pure personnel guarding.

  4. 04

    Guarding context (theft vs. vandalism)

    Theft protection typically needs one person with police radio contact plus photo documentation. Vandalism/activism protection (e.g. politically sensitive large projects) often requires two persons plus de-escalation training. Pay grade and headcount differ.

Frequent questions on construction-site security costs

What does construction-site security cost per night?
A 12-hour night watch (19:00–07:00) on a standard site in Greater Erfurt + 40 km costs between €320 and €420 per night — depending on qualification, weekend supplements and travel. Mobile patrol (4 checks per night) from €280 per night per site. For long phases >12 weeks, hourly rates drop 5–10% via recurring-mandate conditions.
What does construction-site security cost per month?
A 7-day night watch 12 hours daily sums to €10,000–€13,000 per month. Hybrid concept of personnel + 2 video towers typically runs €9,000–€11,000 per month — with the same security depth. Large sites with 24/7 full guarding and certified industrial security run €18,000–€25,000 per month. We deliver concrete numbers within 24 hours.
Is construction-site security economically worthwhile?
For construction projects with on-site assets from approximately €500,000 (materials, equipment, steel) professional guarding usually pays — average damage per theft incident in the industry is €8,000–€25,000, and unguarded sites typically register 3–6 incidents per quarter. Sekuris guarding reduces this in active mandates by 80–95%.
Stationary guarding or mobile patrol?
Stationary guarding pays where theft risk is acute (high-value materials, prior incidents, politically sensitive site) — but costs three to four times more per night. Mobile patrol with 4 checks per night reduces thefts comparably in many cases but is no replacement under active threat. For large areas (>1 ha) hybrid concepts with AI video tower are often the best choice.
What does an AI video tower cost?
An autonomous, solar- or battery-powered video tower with AI person detection and connection to our monitoring centre costs from €1,200 per month flat — including setup, dismantling, maintenance and alarm response by Sekuris staff within 8–15 minutes. On sites with large outdoor area, one tower often replaces 2–3 personnel hours per night.
Which insurance requirements does Sekuris meet?
Standard is BDSW-conformant business and professional liability insurance. For insurer-conformant guarding evidence we deliver shift documentation, photo patrol logs, incident reports — all audit-ready in our shift software. For large construction-insurance mandates we provide additional evidence such as fire-safety-watch qualifications or certified industrial security on request.
How quickly can Sekuris start in an acute case?
Standard construction guarding starts within 24–72 hours of inquiry — typical for theft incidents, short construction phases or transitions from a predecessor provider. For larger mandates requiring five or more guards we plan 5–10 working days for selection and onboarding. Mobile patrol or video tower is often deployable within 12 hours.
