ours did the exact same thing. They should be keeping it somewhat tidy, it is a construction site, but there is no need for pure chaos.That may be typical. Ours got cleaned maybe twice. Every day I went to the "trash pile" to see if they threw away something I needed. That's where I got the manuals for the pumps, filter, heater, etc. Also scavenged some unused parts. Later, I recovered the leftover stone from the coping. Broke it into manageable pieces and used them for freeform stepping stones from the decking to the equipment pad. At the end of the job, a cleanup crew came in and picked up the trash pile, added some fill dirt, and pretty much smoothed everything out. For months I found small items they found it easier to cover than pick up.
