Questions about the Site Investigation poster
- What’s on the Site Investigation poster?
- 6 numbered steps. The cheapest money on a project, and the most often cut. Desk study — Geology maps, old plans, mining records and historic land use.; Walkover survey — Ground conditions, water, access, neighbours and existing structures.; Preliminary boreholes — Enough to see the profile and target the main investigation.; Main investigation — Boreholes, trial pits, in-situ tests and sampling to a written p…; Laboratory testing — Classification, strength, consolidation and chemical suites.; Factual, then interpretive — Report the data first, then the parameters drawn from it..

- Who is the Site Investigation poster for?
- Site Investigation belongs to the Civil Engineering section rather than to a school year, because engineering is not something one grade owns. Anyone learning geotechnical can pin it up — a beginner, a student mid-course, or someone revising years later.
- When should you use the Site Investigation poster?
- At the start of any project on ground you have not seen before. A wall chart earns its place by being glanceable from where the work is happening, so Site Investigation belongs on the wall where that engineering work actually happens, within glancing distance, rather than filed away.
- What other posters go with Site Investigation?
- Atterberg Limits, Bearing Capacity and Compaction Control sit alongside Site Investigation in the Civil Engineering section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Atterberg LimitsBearing CapacityCompaction Control
- Is the Site Investigation poster free to download and print?
- Yes. Site Investigation downloads as a free PDF with no account, no email and no watermark, like everything else in the Civil Engineering section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
- What size does the Site Investigation poster print at?
- Site Investigation is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Site Investigation loses nothing.Printing guide
