Since the Time Team people have come and gone we tend to see archaeology as a fair bit of fun to be had on a Sunday afternoon. Sadly, the reality of the excavations is long hard work. The dig itself is not a simple case of having a go at the earth with a shovel. Much of it is being sat in a trench, regardless of the weather, slowly, very slowly, scraping away at the earth until you uncover something.
At least now the archaeologist has something mobile that they can use to store finds. A wheeled set of Linbins from https://www.rackzone.ie/storage-kits-5/bin-racks make a great way for the find cleaners to document and categorise what is found.
It is actually quite unusually for an excavation to take place. Most sites, such as Stonehenge and Avebury, have already been picked clean of anything useful that would add to our knowledge of the site. Almost all excavations happen under the need of rescue archaeology. When a site is discovered during building work it is the law to report it. The archaeologists go in and excavate the site and collect the finds. It is very unlikely that the site will stop the build. Covering up the site is the best protection for it.
