Write the red line first. A surveyor cannot price “the site” if the site is a moving rumour. Then write the quality levels by zone: QL-D everywhere, QL-B on the working area, QL-A on named crossings. That paragraph is the difference between a comparable tender and a beauty contest.
Add access. Night possessions, live carriageways, cover-lifting rules and confined chambers control duration more than hectare-age. If you do not know those constraints yet, say so; do not pretend the plot is a Sunday morning car park.
Name the methodology type if you have a view, or ask the surveyor to propose one. M1 on a city-centre slab is a category error. M4P on an empty field is how fees inflate. The CICES client guide exists for this conversation.
Name the files. CAD grid, GIS yes or no, chamber cards, residual-risk note. If several designers will share the model, say that once. Then attach the topographic survey so nobody invents a second coordinate system.
Finally, put HSG47 in the same pack so the principal contractor sees detection as part of the safe system, not as a consultant luxury. Commission the PAS 128 survey early enough that the drawing exists before the first excavation permit. City pages such as London and Birmingham describe local density; the planning logic does not change.
Invite residual risk in the brief. If you punish bad news, you will receive a tidy drawing and a surprise in the trench. Ask the surveyor to list services expected but not found, and ground that defeated the method.
Align the survey with the topographic survey. Two grids are how clashes hide. If the topo does not exist yet, say whether the utility survey must wait or can establish control.
Think about the people who will hold the file after issue. If that list includes an asset owner, buy GIS now. If it includes only a civils modeller, CAD may be enough. Decide once.
Then put a date on the wall: drawing needed before the first permit, not the week of the first excavation. PAS 128 is pre-construction information. Treating it as a same-week add-on is how it arrives after the bucket.
Assign an owner inside the client team. Surveys that “everyone” owns are surveys that nobody chases when a statutory return is late.
Hold a fifteen-minute readout when the drawing is issued. Point at the residual-risk crossings. Point at the assumed routes. Then stop talking. The file should do the rest.
If the design changes after issue, budget a revision. Planning a survey is not only the first instruction. It is the decision to keep the information alive until the ground is closed.
A planned survey is a date, a boundary, a quality-level mix and a named owner. Everything else is commentary. Write those four facts first and the rest of the PAS conversation becomes a checklist rather than a debate.
Take this into the brief
Put a date on the wall: drawing needed before the first permit. Assign a client-side owner who will chase late returns. Hold a fifteen-minute readout at issue and point at assumed routes. Those three calendar acts are planning. Everything else is commentary.
If the design moves, budget a revision. A planned survey that is allowed to rot is not planned. PAS 128 is pre-construction information. Treat it that way and the rest of the specification conversation becomes a checklist.
