How to prepare a site-readiness checklist before the installation crew arrives ART-169

Establish the exact requirements baseline

The most dangerous mistake is to build the checklist from a series brochure or the previous machine's design. Even an identical model name does not guarantee identical transformers, chiller, automation, loading, filtration, gas options, masses or dimensions. Before checking, freeze the delivery identification:

• model, serial-number or order-specific configuration and documentation revision;
• source power, cutting-head type and auxiliary processes;
• loading, unloading, storage, conveyors and protective guarding scope;
• separate cabinets, chillers, compressors, filters, gas generators and other external modules;
• agreed layout with all connection points;
• date and author of every change affecting building or utility work.

One documentation owner maintains the revision register. If the electrician works from drawing R2, the builder from R3 and the installers arrive with R4, a formally completed checklist does not prove readiness.

Create a readiness record, not a yes/no list

Each checklist item must contain seven fields: requirement, requirement source, inspection point or area, acceptance criterion, evidence, responsible party and status. Useful statuses are `PASS`, `CONDITIONAL`, `BLOCKED`, `NOT_APPLICABLE`; the last requires written justification. A `PASS` without a document, measurement or inspection has little value.

Evidence may be an as-built drawing, measurement report, test record, photograph referenced to the plan, equipment data sheet, connection-point label or signed walkdown. Do not turn photographs into universal evidence: they show conditions at the time of capture but do not confirm concealed utilities, load-bearing capacity or electrical parameters.

Visually, the readiness record is conveniently divided into eight gates: documents, building work, logistics, electrical supply, gases and pneumatics, extraction and climate, digital interfaces, and safety and work organization. Mobilization is authorized when each gate's critical items are closed or have a temporary arrangement agreed in writing.

Gate 1: premises and base

Check more than the machine's rectangular footprint. Actual floor elevations, completed openings and embedded fixtures, access to anchoring points, and absence of conflicts with columns, gates, crane routes, cable channels and evacuation routes are needed. If the structural design specifies concrete curing, grouting or a separate foundation, the schedule must allow the required condition to be reached before installation.

The checklist includes:

• base geometry matching the approved plan;
• load-bearing capacity confirmed by a competent designer;
• flatness and local level differences against OEM criteria;
• readiness of pits, channels, penetrations and edge protection;
• dryness, cleanliness and no unfinished dust-generating work;
• clear service, logistics and emergency areas;
• future access to filters, tanks, cabinets and replaceable assemblies.

Do not accept “we will level it with the machine.” Mounting supports compensate only for what the manufacturer permits; they do not correct an unsuitable foundation or workshop geometry.

Gate 2: delivery route and rigging

Check the route from the site entrance to each module's final position. Compare transport dimensions and masses, not the assembled machine's operating appearance. Record gate width and height, turning radii, slopes, surface load-bearing capacity, channel covers, overhead obstructions and temporary storage locations.

Separately agree who provides the crane, forklift, slings, spreader beams, jacks, riggers and signaler. Lifting equipment must be suitable according to its documentation and local requirements; this article does not replace a lifting plan. OSHA 1910.176 is used here only as an official example of the principle of adequate aisles and safe material flow in the US jurisdiction, not as a Ukrainian regulation.

A practical test is to walk the route with the plan, a tape measure or survey data, and a mock-up of the largest transport package. If a fence or gate must be temporarily removed for passage, that work must be completed with safe reinstatement possible before the cargo arrives.

Gate 3: electrical supply and grounding

IEC 60204-1 publicly defines the machine's electrical equipment as beginning at the supply connection point. This is a useful responsibility boundary: customer infrastructure must bring verified power to the agreed interface, while connection and internal machine checks follow manufacturer documentation.

The readiness checklist checks the distribution board, disconnecting device, route, labeling, protective conductors, agreed connection points and access to them. Reports must reflect the actual condition of the prepared network. Voltage presence does not prove adequate capacity, power quality, protection selectivity or grounding compliance.

Do not connect the machine with a “temporary” cable without a written engineering decision. A temporary scheme often changes protection, routes, fire risk and responsibility, and tends to become permanent after startup.

Gate 4: gases, compressed air and cooling

For each medium, record the gas or liquid, connection point, permitted range, purity, peak flow, shutoff-valve condition, labeling and test report. A pressure-gauge reading without flow does not confirm dynamic capability. A gas certificate for the tank does not confirm purity after a long or contaminated main.

An oxygen line needs components and procedures suitable for oxygen service; ordinary pneumatics are not automatically acceptable. A competent party must accept the gas supply against the local design. If the chiller is external, check its location, electrical supply, pipe routes, permitted medium and serviceability. If it is integrated, do not invent external requirements absent from the package.

Gate 5: extraction, ventilation and microclimate

Extraction must be not merely installed but ready at the agreed interface: filters fitted, ductwork completed, power available, discharge or recirculation resolved by the design, and direction and operating mode checked. Assess capacity against the specific machine's and materials' requirements; a universal number from another model is unacceptable.

Assess temperature, humidity and dust conditions where the machine and external modules are located. If building work still generates abrasive dust, installation of optics and cabinets risks contamination. The checklist must define the transition from construction conditions to clean installation conditions.

Gate 6: networking, data and service access

Before the crew arrives, determine which network functions are actually needed for commissioning: licensing, program transfer, diagnostics, updates or remote support. Prepare the segment, addressing, access rules and responsible people, but do not open a permanent uncontrolled channel “to start faster.”

Backups of initial settings, an agreed file-transfer medium and a procedure for temporary supplier access are needed. This check does not duplicate the cybersecurity architecture in ART-163; it only confirms that an agreed interface is available on installation day.

Gate 7: safety and work organization

Before mobilization, define the customer coordinator, installation manager, authorization procedure, working hours, briefing language, emergency contacts, barrier zones and rules for simultaneous work. Installers must not share an area with builders without agreed risk controls.

ISO 12100 provides a general framework for risk assessment and reduction throughout the life cycle, but the standard's public page is not a ready-made risk assessment. Responsible parties prepare the actual safety plan for the specific equipment, rigging, energy sources and local requirements.

Check lighting, housekeeping, fire-access routes, packaging and waste areas, first aid, sanitary facilities and control of unauthorized access. Keys, permits, passes and an on-duty engineer's contact must be available from the first shift.

Gate 8: documents, people and resources

Installation can stop because a decision, not a part, is missing. Prepare the current layout, interface diagrams, utility as-built documents, test reports, nonconformity list, designers' contacts and authority for prompt approval. Define who will participate in training, acceptance and handover into operation.

Check equipment storage, security, unpacking space, packaging disposal, access to lifting equipment and consumables explicitly specified by the OEM. Do not buy arbitrary oils, gases or fittings “by analogy”: delivery documentation confirms compatibility.

Conduct a dry walkdown

A few days before mobilization, gather representatives of the customer, general contractor, electrical, gas, ventilation, IT and equipment supplier teams. Walk the physical route from unloading to every connection point. On site, verify the plan revision, labeling, coordinates, elevations, access and completion of work.

Enter every nonconformity in a punch list with a category:

• red — creates danger or blocks delivery, positioning or connection;
• yellow — does not block the entire installation but has a deadline, owner and agreed closure method;
• green — completed and confirmed by evidence;
• gray — not applicable, with explanation and approval.

Do not conceal a red item behind a plan to “solve it on site.” The cost of a specialist crew's downtime and remobilization is usually higher than an inconvenient but timely date change.

Mobilization decision

Document the final decision in a brief readiness certificate. State the configuration, requirements revision, walkdown date, closed gates, remaining items, access conditions, confirmed responsible people and a `GO` or `NO-GO` decision. A signature does not automatically transfer responsibility; it records a shared understanding of actual conditions.

`GO WITH CONDITIONS` is possible only when a condition creates no danger and does not interfere with the critical sequence. For example, cosmetic labeling may be completed later; an unconfirmed connection or blocked rigging route may not.

Bystronic describes preparation, delivery, installation and commissioning as sequential project phases. This is not a universal contractual procedure for every supplier, but it clearly shows the logic: site readiness has its own outcome and must not quietly be shifted into installation.

What to give the installation crew

Before arrival, send one controlled package: access map, coordinator contact, access rules, approved layout, transport-package list, the responsible party's rigging plan, connection points, readiness certificate and open punch list. Mark all changes after dispatch separately.

On the first day, conduct a brief joint inspection. If actual conditions differ from the package, pause work in the affected area and assess the change. The installation crew must not independently redesign the foundation, gas piping or electrical network to save the schedule.

Typical signs of false readiness

A site cannot be considered ready when there are only verbal confirmations, utilities end “somewhere nearby,” documents have different revisions, the route has not been checked against transport dimensions, extraction is untested and safety is left to installers after arrival. Another sign is one overall readiness percentage. Ninety-five percent says nothing if the remaining five includes a missing power supply or crane.

A good checklist makes blockers visible early. Its purpose is not paperwork protection, but a safe, predictable transition from workshop preparation to installation. After installation, the object of control changes: infrastructure must be accepted separately, and its evidence must not then be confused with tests of the machine itself. ART-170 addresses this boundary.

Minimum evidence set by gate

To avoid arguments about “ready,” agree the minimum evidence for each group in advance. For building work, this means an approved as-built drawing, designer confirmation and required measurement results. For the delivery route, a signed walkdown, dimensional check and confirmation of lifting-equipment suitability. For electrical supply, a single-line diagram, labeling, protective-measure verification reports and an agreed isolation point. For gases and air, a diagram, medium identification, test reports and confirmation of parameters at the point of use.

Extraction needs an up-to-date diagram, completed installation, serviceable filters and a functional-test result. IT needs agreed addressing, account roles, a temporary remote-access rule and a responsible administrator. Organizational readiness needs a list of people, authorizations, briefings, contacts and available resources. If a particular piece of evidence is not required by the OEM or local design, do not create it as a formality; state why the item does not apply.

Control changes after the GO decision

Site conditions can change between the walkdown and crew arrival. A contractor may block a gate, dismantle a duct section, de-energize a panel or store material in a service area. The readiness certificate therefore needs a validity period and a list of conditions that cannot change without rechecking.

One day before delivery, the coordinator performs a brief delta-check: route, unloading area, base, connection points, barriers, and access for people and equipment. Check changes specifically, rather than mechanically repeating the entire audit. A new nonconformity receives an owner and decision; a critical one automatically returns the status to `NO-GO`.

It is also useful to freeze the list of parallel work. Welding, painting, wall chasing, work at height or heavy-equipment movement near the installation may change dust, fire or logistics conditions. Either finish these before mobilization or separate them in space and time under an agreed safety plan.

Assess the checklist by decision quality

The number of rows is not a maturity indicator. A strong checklist answers four questions unambiguously: can the equipment be delivered safely, can it be positioned according to the current layout, are all agreed interfaces ready, and can the team manage a deviation without improvisation? If the answer requires a call to someone not involved in the decision, responsibility is not yet established.

After every installation, hold a brief lessons-learned review. Record which items actually prevented downtime, which evidence proved weak, which requirements arrived late and what should enter the next project's template. Update the structure, but do not transfer numerical parameters between machines: reuse the control method, not another machine's technical values.

Add a resource-availability check

An item may be technically closed but operationally unavailable on installation day. For example, a serviceable crane is booked by another department; an accepted electrical panel has its key held by an absent duty engineer; a network segment exists, but its administrator does not work the crew's shift. For critical resources, therefore specify not only compliance but a confirmed availability window, backup contact and response time.

Prepare a day-one resource sheet: lifting equipment, operators, rigging, gate access, keys, electrician, gas, ventilation, IT and security specialists, and a person authorized to approve deviations. Record the time, meeting location and authority boundary for each. This sheet does not replace permits or the work plan, but removes organizational delays.

Check backup arrangements only where they are safe and approved. If the crane is unavailable, a backup forklift does not automatically become suitable. If the main power supply is not ready, a portable generator is not an equivalent substitute. The backup must pass the same relevant criteria as the primary resource.

Close readiness for the entire configuration

The main frame is often ready before automation, the chiller, filter or gas module. Track readiness by transport package and system, not only by the central machine. If partial installation is permitted, record the sequence, temporary storage, component protection and transition criterion for the next phase.

In the final review, reconcile the packing list with the site: where each module goes and whether its route, base, resource and service access are ready. This is not checking delivery completeness on the supplier's behalf; it confirms that no known component lacks a prepared location.
