The assumption
[Write the misconception here, in the words clients use. Two or three paragraphs. Do not defend yet — just state the belief and note what it costs: the fee expectation it sets, the timeline it implies, and the assessments that never get commissioned because access looks hard.]
What the documents establish
[This is the load-bearing section and the proof of competence. Name the documents specifically — datasheets, line lists, P&IDs, PFDs, plot plans, GA drawings, material take-offs, vendor data books, design basis. For each, say what it pins down. Specificity is the entire argument.]
[Show one short chain of inference. A datasheet gives design pressure and material spec → that fixes the piping class → that fixes a rate per metre → applied to the line list length.]
[Invent the numbers. No real asset, no real client, no figure traceable to an engagement.]
What a visit adds
[Draw the boundary honestly — this is what makes the piece credible rather than promotional. Condition. Undocumented modifications. Congestion and access affecting reinstatement labour and lift plans. As-built drift from as-designed. Be specific about when a visit stops being optional.]
Why the boundary matters
[Land the commercial consequence. Restricted-access sites. Operating assets that cannot be walked freely. Mobilisation cost and time. Assessments that are feasible when the constraint is understood correctly, and refused when it isn't.]
The actual bottleneck
[Close on the harder observation — that obtaining the document set is the real constraint, not physical access. What a client can do to shorten that. This is the most original thing you have; give it room.]
