The provided section includes typical combined service trench arrangements, specifying marker tape placement above water mains and tracer wires, warning strip offsets from surfaces, and clearances to other services. It also defines trench fill and embedment materials, geotextile filter and overlay requirements, bedding depth to prevent joint contact, and key installation notes for compaction, support types, and
