For an OEM or machine builder, the installation partner you appoint travels to a site you do not control and represents you to your customer. Choose well and the machine starts cleanly and your reputation grows; choose on day-rate alone and a poor installation can void warranties, expose your know-how and damage a customer relationship you spent years building.
Start by defining what you are handing over. The full installation, alignment and commissioning scope, the acceptance criteria and sign-off, the timeline and customer-facing milestones, and a clear split of what you provide versus what the partner provides — tools, parts, drawings, consumables. Ambiguity here is where commissioning slips and blame circulates.
Verify capability against the work, not the brochure. Confirm mechanical, electrical and controls competencies on staff; metrology and precision-levelling capability; site-safety qualifications valid for the destination country; and references for similar machinery, sectors and complexity. Where your customers are international, check regional coverage and language so the crew can actually function on site.
Treat conduct as part of the specification. On site, the field crew represents your brand. Reporting standards, professionalism, appearance and communication with the customer matter as much as the technical work — your customer will judge you by them long after the machine is running.
Settle liability, warranty and IP before mobilisation, not after an incident. Confirm professional and public liability cover appropriate to the work, clarify responsibility for damage and for downtime if commissioning slips, and make sure the partner's work preserves rather than voids your machine warranty. Tie confidentiality and IP protection for your designs into the contract explicitly.
Then choose on accountability. A single point of contact for the whole engagement, a documented handover with as-built records and acceptance reports, and real-time visibility of progress and sign-off are what turn a field installation into something you can stand behind in front of your customer.
