Pre-Sale Site Surveys for Paper Machinery: A 2026 Quotation Guide
In 2025, sales engineer Lucia Ferreira at a paper machinery builder in Sao Paulo, Brazil, closed a contract for a napkin converting line and then spent the next two months managing a problem that should never have existed. The machine was correct; the building was not ready for it. The existing ceiling beam sat 40 centimetres lower than the delivery path required, and the electrical supply at the wall was one phase short of the machine rating. Her team had relied on customer-supplied measurements rather than a site visit. The turning point came when the plant manager asked a simple question during the delay review: why had nobody stood in the hall before signing? What follows is the structured pre-sale survey we now treat as a condition of quotation.
Why a Quote Without a Site Survey Is a Guess
A paper machine quotation is a promise about a machine in a building. If the building is not measured, the promise rests on assumptions, and assumptions are where projects lose money. The most expensive assumptions are rarely about the machine; they are about the space around it and the services feeding it.
A pre-sale survey exists to convert assumptions into facts before the price is fixed. It protects both sides. The buyer gets a quotation that reflects reality, and the supplier avoids the margin erosion that comes from discovering a constraint after the contract is signed. The cost of a survey is trivial next to the cost of a machine that cannot be installed on schedule.
Machinery safety and risk assessment follow ISO 12100:2010, which requires that the intended use, the space, and the surrounding conditions be understood before risks are evaluated. In a pre-sale context, the same principle applies commercially: a machine cannot be assessed against its environment until that environment has been measured.
The Measurements That Decide Feasibility
A survey does not need to be elaborate, but it must cover the dimensions that decide whether the machine fits and runs. Missing one is enough to stop a project.
| Measurement | Why it decides feasibility | Typical risk if missed |
|---|---|---|
| Floor area and machine footprint | Whether the line physically fits | Line cannot be installed as quoted |
| Ceiling height and headroom | Whether the machine clears beams and ducts | Delivery or operation blocked |
| Foundation load capacity | Whether the floor carries the load | Structural reinforcement after order |
| Door and aisle clearance | Whether the machine can reach the hall | Crane or wall removal at cost |
| Power supply and phase | Whether the drive can start | Transformer or panel upgrade |
| Compressed air, water, drain | Whether the process can run | Utilities installed after machine arrives |
The lesson from Lucia's project is that a single under-measured dimension, in her case the ceiling beam, can outweigh every other detail that was checked. The survey is only as good as its weakest line, so the checklist must be complete even when it feels routine.
In surveyed machinery projects, headroom and delivery path clearance are the two measurements most often found short on the day of installation, and each can force a building modification whose cost can exceed a meaningful share of the machine price.
A quotation is a promise about a machine in a building; measure the building before you make the promise.
Utilities and Structural Checks
Utilities and structure are the quiet risks in a machinery project because they are invisible in the machine contract and expensive to change late. The survey should record the available supply values at the actual connection point, not at the plant boundary.
Compressed air is a common surprise. A line quoted on nominal plant pressure may need more flow and pressure than the existing compressor can deliver at the point of use, and the difference is a new compressor, not a new hose. Power is the other frequent surprise, because a drive rated for one phase configuration may not match the supply in the hall. Recording actual values with a meter, rather than asking for nominal values, is what makes the survey useful.
Quality management for quotation and contract processes follows ISO 9001:2015, which requires that requirements be determined and reviewed before a commitment is made. A recorded site survey is the evidence that the requirement review actually happened, and it protects the supplier in a dispute about whether the site conditions were disclosed.
Documenting the Survey into a Quotation
A survey creates value only if it enters the quotation. The document should state the measured facts, list any remaining assumptions explicitly, and connect each assumption to a price or schedule consequence.
The simplest format is a short table of facts, followed by a short table of assumptions, followed by the price. Every assumption should have a line that says who confirms it and by when. When the buyer signs, they sign the assumptions as well as the price, and the later conversation about a missing phase or a low beam becomes a change order rather than a dispute.
When the Site Cannot Be Visited
International orders sometimes must be quoted before a visit is possible. That is not a reason to skip the discipline; it is a reason to label the quotation clearly.
Issue a provisional quotation, mark every figure that depends on site data, and require either written confirmation from the buyer or a remote video survey with measurement checks. A remote survey is not a substitute for a physical one, but it catches the gross errors that cause the worst delays. Teams building the delivery plan after the survey should review our [paper machinery installation and commissioning checklist](https://yoco-group.com/blog/paper-machinery-installation-commissioning-checklist-guide-2026), which starts where the survey ends, and the export logistics side is covered in our [paper machinery export shipping guide](https://yoco-group.com/blog/paper-machinery-export-shipping-guide-2026).
Frequently Asked Questions
Can a paper machine be quoted without a site survey?
It can be quoted, but the quote will carry assumptions that shift cost and schedule later. A short structured survey before quotation removes most of that risk and usually costs a fraction of a single day of wrong installation.
What must a pre-sale site survey measure?
At minimum the available floor area, ceiling height and headroom over the machine path, foundation load capacity, the door and aisle clearances for delivery, and the available power, compressed air, water, and drain capacities at the connection point.
What happens if the site cannot be visited?
Industry practice is to issue a clearly labelled provisional quotation based on customer-supplied data, list every assumption, and require written confirmation or a remote video survey before the order is confirmed. The assumptions must be visible to the buyer.
Who should attend the survey?
A survey is most useful when the machine supplier and the customer's plant engineer attend together, because the supplier sees the machine requirement and the plant engineer sees the building constraint. A survey done by one side alone tends to miss the other side's limits.
