We engineer the power, security, fire and automation layers that hold a business together — so downtime, loss and life-safety risk stop being your problem to manage. One assessment. One accountable engineering partner. One system that keeps working.
Every DopCellar engagement starts with the operational risk you're trying to remove — not a shopping list of hardware.
Integrated CCTV, access control and perimeter systems — evidence-grade footage and real-time alerts.
Solar-hybrid, inverter and switchgear engineering built for continuous business operations.
Certified fire detection, suppression and alarm systems — engineered before an incident becomes a disaster.
Load audits, right-sized hybrid systems and metering that turns energy from a bill into a managed asset.
MEP upgrades, structured cabling and BMS-ready electrical backbones — one integrated platform.
Most Nigerian operators treat security, power, and fire as separate problems. That's why they fail together. We built DopCellar because they don't have to.
Security, power, fire safety, network and building systems — engineered as one platform, not stitched together from separate vendors.
Every project runs against documented standards, structured commissioning and traceable acceptance records — the same rigor Tier-1 clients expect.
SLA-backed preventive maintenance keeps systems operational long after installation — no orphaned deployments.
Fire, electrical and security work executed to relevant Nigerian regulatory codes with the documentation auditors and insurers require.
Head office in Ibadan, branch in Port Harcourt, and mobilisation capability across Nigeria's commercial corridors.
Direct engineering escalation — not a call centre. Mission-critical sites get engineer-led response, not a ticket queue.
We are deliberate about not decorating this website with logos we haven't earned or numbers we can't evidence. Instead, judge us on the things you can verify before you commit a naira.
Every engagement produces drawings, load calculations, specifications and a commissioning record. You can hand our documentation to an independent consultant before you sign anything.
Assessment scheduled within 48 hours. Escalation reaches the engineer on your account — not a queue. Response tiers are written into the agreement, not implied.
Preventive schedules, condition reports and spare-parts planning are designed in from day one. Systems that are maintained are systems that stay operational.
DopCellar Merit was formed by engineers from the Cellar Brothers network — carrying forward established field discipline, supplier relationships and installation standards into an integrated infrastructure practice.
Costed engineering pathways with line-item scope. No hidden change orders, no vague allowances. If a variation is needed, it is raised, priced and approved in writing.
We are building a national integrated infrastructure practice — which means our incentive is your system performing in year five, not the invoice in month one.
Ask us for a reference design, a commissioning checklist or a maintenance schedule template before you engage us. Firms that hide their method rarely have one.
Most operators buy security, power and fire from different vendors. When something fails, no one owns the outcome. We built DopCellar as one platform so accountability, data and control live in one place.
One engineering team, one drawing set.
One handover, one acceptance record.
One SLA covering every discipline.
Every sector below reflects a specific operational-continuity brief we've engineered against — not a generic service list.
Continuity for lean teams.
Regulator-grade branch uptime.
Zero-tolerance life-safety.
Safe, monitored learning environments.
Guest-experience-grade reliability.
Measurable plant uptime.
Compliance and lifecycle accountability.
Tenant-ready on day one.
These are our design blueprints — the engineering logic we apply per environment. Every one of them is discussed openly with your team before a single cable is pulled.
Load-audited hybrid power with automatic changeover, evidence-grade camera coverage over cash points, and audited door control — designed so a grid failure never becomes a service failure.
Zoned detection and alarm design, emergency supply for critical circuits, and a commissioning pack that gives clinical leadership documented proof that each zone was tested.
A single integrated electrical and cabling backbone with labelled, as-built documentation — so landlords hand tenants an infrastructure pack instead of a mystery.
Switchgear and distribution engineered around process criticality, perimeter coverage on the routes that actually matter, and a preventive schedule tied to plant run-hours.
Every engagement follows the same discipline — from first site visit to lifecycle support — so operations leads know exactly what happens next.
Engineer-led survey, load analysis and operational risk review — signed off before a single line item is quoted.
Costed engineering pathway with drawings, specifications and integration plan — reviewable by your own consultants.
Certified engineers, sequenced delivery, structured commissioning and acceptance testing with documented handover.
Preventive service schedule, response SLA and long-horizon support so systems keep performing years after go-live.
Practical guides, compliance whitepapers and short insights from the DopCellar engineering team.
How to calculate branch load profile, battery autonomy and PV array size for regulator-grade uptime.
The specific documentation, drawings and certifications insurers and regulators demand at hand-over.
When CCTV, access control and alarms live with different vendors, the seams — not the cameras — are where losses happen.
The questions operations leads, procurement teams and CFOs ask us before signing.
Because we will not publish credibility we have not earned. DopCellar Merit is a young integrated practice built by experienced field engineers, and we would rather you judge us on our engineering method, documentation and response commitments — all of which you can inspect before you engage us — than on numbers you cannot verify.
Still weighing it up? Put the question to an engineer — no obligation attached.
A senior engineer walks your site, maps where continuity actually breaks, and returns a documented pathway you can hand to your own consultants. There is no cost and no commitment attached to it.

You share the site and the operational risk that worries you.
An engineer visits, surveys and documents what is actually there.
You receive a costed engineering pathway — yours to review, keep or decline.
