AEFINTYR LLC Fused. Tested. Lossless.

Six trays. One practice. Every joint proven.

AEFINTYR LLC is a systems design consultancy for connected operations, working from its laboratory at 2227 3rd Ave SW, Rochester - 55902-2307, United States (US). This page sets out the six disciplines we hold on the bench. They can be engaged separately, but they are strongest when a single engineer keeps them joined from survey to acceptance.

The six trays

What each discipline contains

Each tray below opens a full account of the work. Read the whole wall if you are planning a new facility. Read one tray if a single problem is keeping you up at night.

Systems Architecture

Systems architecture is the discipline of deciding what a connected operation is made of before anyone buys a device. We begin with the operational brief, not the product catalog. What must the facility do on an ordinary Tuesday, what must it do during a utility failure, and what must never happen under any condition. Those three questions generate the failure domains, the redundancy level and the boundaries between subsystems.

From there we produce a layered architecture: the physical layer of rooms, racks, pathways and power, the network layer of addressing, segmentation and routing, the integration layer of controllers and data models, and the supervisory layer of monitoring and reporting. Each layer names its dependencies openly so that a client can see where a single point of failure has been accepted on purpose and where it has been removed at cost.

The deliverable is a reference document with drawings, a device schedule and a written statement of what the system will and will not do. It becomes the arbitration point for every later trade, which is exactly why we insist on finishing it before procurement starts. A system designed in this order does not need to be explained later, because the explanation already exists as the design.

Network and Cabling Design

Cabling is the part of a system that is hardest to change and easiest to get wrong. We design structured cabling with the same care a structural engineer applies to steel. Cable categories, jacket ratings, bend radii, tray fill, separation from power and the routing of every run are resolved on paper so the installation is a build rather than a negotiation.

Our network design covers topology, addressing, virtual segmentation and wireless coverage. We model where the access points must sit for the actual materials in the walls, not for an open plan that does not exist. We plan the uplinks and the power over ethernet budget per closet, then verify that the switch schedule can carry the load with room to grow.

Everything is documented in a patch schedule that maps each port to its destination and its purpose. When the project closes, a technician can trace any fault from a wall outlet to a switch port without opening a single drawing roll. That single habit removes hours from every future move, add and change on the site.

TR-03 / Service 03

Integration Engineering

Integration engineering is the craft of making separate vendor systems behave as one. A building rarely fails because a camera is bad. It fails because the camera system, the access system and the alarm panel each hold a different idea of who is in the building. Our engineers define a common data model and an interface contract, then hold every vendor to it.

We work across the protocols that matter in modern facilities, from building automation and industrial control to application programming interfaces and message queues. Every interface is tested against real traffic in a staging environment before it is allowed into production. A interface that only works in a demonstration is not an interface, and we do not accept one.

The output is a map of every integration point, its owner, its data shape and its failure behaviour. When a vendor changes a firmware version, the map tells the client exactly which contracts need retesting. Integration stops being a mystery and becomes a maintained asset with a known surface.

Monitoring and Observability

Monitoring and observability answer a simple question: how does the system tell us it is unwell. We start by deciding which assets deserve telemetry and at what granularity, because collecting everything produces noise and collecting nothing produces blindness. Each monitored point is chosen because an operator can act on it.

We define thresholds with the client in the language of consequence, not raw engineering units. A temperature alert matters because a room will overheat in forty minutes, so the alarm is set and worded to say exactly that. Dashboards are designed for the person on call, with the most consequential reading nearest the top and the drill down path obvious.

Alarms are tied to runbooks so that every alert has a documented first response. We also design the health of the monitoring system itself, because an alarm platform that fails silently is worse than no platform at all. After handover we tune thresholds against real data, which is the step most integrations skip and most operators wish they had not.

Documentation and Compliance

Documentation is where a system becomes permanent. We produce as built drawings that reflect what was actually installed, an asset register with serial numbers and warranty dates, a structured cabling test record and a maintenance schedule with tasks and intervals. These are living documents, delivered in editable formats, not a one time folder.

When a client carries regulatory or accreditation duties, we map the installed evidence to the clause it satisfies. That mapping turns an audit from a scramble into a lookup. We are careful and honest about scope here: we prepare and organise evidence, and we work alongside the client compliance advisors rather than replacing them.

We also write the operational runbooks that a new technician will need on their first night shift: how to isolate a subsystem, how to restart a controller in the correct order, who to call and when. A well documented system survives staff turnover. A poorly documented one becomes a mystery that grows more expensive every year.

TR-06 / Service 06

Technical Project Management

Technical project management is the discipline that keeps design intent alive through delivery. Integration projects rarely fail because the drawing was wrong. They fail because the sequence drifted, a trade worked around a blocked pathway, or a test was signed off on a verbal assurance. Our manager holds the schedule, the interfaces and the gate criteria.

We run a risk register that is reviewed with the client at a fixed cadence, and we report readiness in plain terms rather than percent complete. A room is either ready for commissioning or it is not, and our reporting says which, with the outstanding items named. That clarity is what allows an owner to make a real decision about opening a building.

We also witness the tests that matter: cable certification, interface acceptance and failover drills. The manager on your project is technical enough to challenge a result and independent enough to stop a handover that is not ready. The go live gate is a formal step, and it is never waived to protect a date that was optimistic from the beginning.

AEFINTYR LLC opens its winter advisory calendar for new Rochester clients, and bundled scopes of three or more services receive priority bench time.

Process

How an engagement runs

Whichever services you engage, the work moves through the same four stations. The sequence protects the client from expensive rework and protects the design from being diluted during construction.

Station 01

Survey and brief

Site walk, operator interviews, records review and a written brief with declared unknowns. Fixed fee, deliverable in hand before design begins.

Station 02

Design and schedule

Architecture, cabling, integration and monitoring resolved together, plus a device schedule and costed scope a contractor can price directly.

Station 03

Build witnessing

Requests for information answered, installations inspected and deviations caught early, with interface tests run in staging before production.

Station 04

Test and handover

Certification, acceptance tests, failover drills, as built records, training and a stabilisation window with the named engineer reachable.

Engagement shapes

Three ways to bring us in

Design only

You have a contractor and a build date. We deliver the architecture, the drawings, the schedules and the acceptance criteria, then hand the package over for construction. Ideal when the client has strong delivery capability but wants an independent design authority.

Design and witness

We hold the design and stay through construction to inspect, answer requests for information and witness the tests. This is our most common shape because it keeps the design intent intact to the end of the job.

Recovery

A system was delivered and nobody can explain it. We rebuild the documentation from what is installed, re measure the links, map the integration points and hand back a system with a truthful record and a plan to correct what is wrong.

Tell us what has to stay running

Every engagement starts with a short conversation about the operation you are protecting. Give us the site and the constraint, and we will tell you which trays of the bench the work will touch.
