Data-centre engineering infrastructure and operation

A data centre from first discussion to commissioning

We write the functional requirements and the brief, run pre-design and design, check and accept equipment, prove the system in testing and put the site into operation.

Situations

When you need us

At the very start

The client knows they need a data centre but not what for. There are no functional requirements, no brief and no preliminary calculations.

A site for AI load

An investor or developer is designing a site for high rack density and liquid cooling.

A design in hand

The general designer lacks data-centre expertise and requirements for future operation.

Commissioning soon

The site is close to commissioning, but there is no team, no procedures and no tested failure scenarios.

Work

What we do

Control at every stage: from the first document to signed commissioning acts.

01
Requirements and FR

Functional requirements, pre-design and design briefs, capacity, reliability, phasing, room schedule.

Documents the client approves, hands to the designer and uses to request technical conditions (TU)

02
Pre-design

Site, energy balance, redundancy, layout options, budget based on comparable sites, roadmap under GOST R 58811-2020.

Parameters used to approve the budget and meet the technical conditions (TU)

03
Design

Design support: assignments for related sections, control of decisions at the design and working-documentation stages, preparation for expert review.

A design that accounts for acceptance and future operation

04
Design review

Uninterruptible and guaranteed power systems, UPS and gensets, 0.4 kV switchgear, points of failure, switching logic, maintenance without shutdown.

A risk register and comments that go into the design, not onto the site

05
Equipment procurement and acceptance

Specification, supplier pre-qualification, lead times, spares and service, FAT, SAT and SAP programmes in the supply contract.

The cost of operation, not just the price of supply and start-up

06
Construction and testing

Technical supervision during installation and start-up, loss of external power, failure of an uninterruptible power or cooling branch, partial automation, alarms.

L4 and L5/IST test reports, a closed punch list

07
Commissioning

Chief engineer and shift engineers, SOP, MOP and EOP, drills, SLA and KPI, incident reviews, preventive maintenance and spares.

At commissioning the site, the people and the processes are ready

First step

The first stage takes up to 20 working days

No documents yet

We start with requirements: client goals, site, functional requirements, pre-design brief.

You have FR, a brief or a design

We review the inputs. If you have both the brief and the FR, send both: discrepancies only show when the pair is reconciled.

Counted from receipt of the materials. Scope and price are set after we review the inputs.

Deliverables

  • Register of technical and operational risks
  • Comments on design decisions
  • Equipment requirements before the order is placed
  • Monitoring and automation requirements
  • Requirements for future operation
  • Testing and acceptance scope

Acceptance

A data centre is tested as a system

Integrated testing proves how the system behaves, not that all the equipment is in place.

Loss of both feeds

Loss of both utility feeds: the load holds on UPS, the gensets start, the site returns to the grid without a dip.

Pre-design calculation for a 6 MW AI data centre

The first phase is mixed: colocation sells from day one, the AI zone grows in blocks for a confirmed customer.

  • Energy balance with battery recharge and a check for degraded EER
  • Three risks before design: density growth, cluster power spikes, redundancy on a hot day
Composition

Platform

Our tm.hub platform

We keep requirements, test results and records in our own platform: the same documents give the same result, and checks follow formalised rules.

Requirements register

The brief and FR are reconciled with each other and with design documents; changes are visible in the history.

Test trail

Programme, result, punch list and re-test are stored together.

Operations history

Procedures, incidents and reviews build up in the site’s knowledge base.

Reports from 1C

Stock, purchases, receivables and shipments right in the chat — during equipment procurement you can see what is paid for and what has arrived.

Questions

In short

At what stage do you start?

Any: from the first discussion and functional requirements, on a finished design, before equipment procurement or before commissioning. The earlier, the cheaper it is to fix what we find.

Do you replace the general designer?

No. The general designer issues the documentation and goes through expert review. We are responsible for requirements, review of design decisions, equipment procurement and acceptance, and the site’s readiness for operation.

How long does it take and how much does it cost?

The first stage takes up to 20 working days from receiving the materials. We price the work from your brief: having built and run data centres for 15+ years, we see where a project will lose money and reliability and design that in from the first document.

What should we send to start?

Any inputs: functional requirements, brief, concept, design, specifications, technical conditions. If there are no documents, we start with a conversation about your goals and the site.

Do you work with AI data centres?

Yes. Densities up to 140 kW per rack and above, liquid cooling, different redundancy schemes for the AI loop and the core, cluster power spikes and genset load steps.

Where do you work?

Russia and neighbouring countries. We run projects in Saint Petersburg, Sochi, the Leningrad Region, Moscow and other regions.
