Before you dig
Values are minimum working dimensions for typical conditions. Depth of bury, soil type, groundwater, traffic control, and shoring or trench box requirements may all demand a larger excavation. Confirm with A&A Drilling before excavating, and follow OSHA 29 CFR 1926 Subpart P for any excavation 5 ft or deeper.
