Collect available site information
Gather surveys, plans, utility information, geotechnical material where relevant, drainage history, known fill, prior construction records, and photographs. Mark which information has been verified and which is approximate.
Plan excavation logistics
Review equipment route, clearance, ground protection, demolition, temporary fencing, material storage, truck access, spoil destination, noise, dust, neighboring conditions, weather, and restoration.
Agree how discoveries are managed
Rock, groundwater, unsuitable soil, undocumented services, buried structures, or contamination can change the work. The contract should describe notification, evidence, options, pricing, authorization, and schedule treatment.
Pool excavation and site conditions: common questions
Can every underground condition be known before excavation?+
No. Investigation can reduce uncertainty, but the project documents should also explain how unforeseen conditions are handled.
Who identifies utilities?+
Confirm responsibilities for utility records, locating services, private systems, potholing where needed, and protection before work begins.
What happens to excavated material?+
The proposal should describe expected reuse or removal, testing if relevant, haulage assumptions, disposal, and site restoration.
