But Lassiter Excavation was so good that I couldn't continue to be lazy.  For context, I was replacing an old 35,000-gallon swimming pool with a skinnier lap pool. Lassiter started by completely removing the massive 1975 pool, including every scrap of concrete and piping.  Then they backfilled and compacted. Working to my soils engineer's specifications, they imported and compacted 18 truckloads of quarry fines in carefully controlled 8-inch lifts through the full 12-foot depth of the deep end, all the way to finished grade. They used multiple pieces of equipment, including jumping jacks, a Bobcat, and a vibratory sheepsfoot roller (which I had to look up), and they coordinated compaction testing throughout the process.  When they were done, it looked like a pool had never been there. The site was fully prepared for the new excavation, which Lassiter then completed flawlessly.  I measured their forms with a laser level and laser tape measure, and length, width, diagonals, position and elevations were all within 1/8 inch. That's impressive considering the new lap pool is nearly 60 feet long. When they were finished digging, the walls and floor were razor straight and right on their marks. The crews were outstanding -- friendly, hardworking, detail-oriented, and consistently professional. They maintained an exceptionally clean jobsite throughout the project and even helped me reclaim some old redwood decking.  Special thanks to Santana, Ricardo, Daniel, Jose and team for answering all my questions and caring so much about the end result. If you're considering any excavation work, I highly recommend reaching out to Lassiter Excavation and talking with Bob. They exceeded my expectations in every respect.

Everything went well and very smoothly. Each step of project was approved and signed by city representative. During entire project Jose was there and monitoring the progress very closely. His crew and team are great, very polite and knowledgeable. I want specifically thank his plumber "Pablo" which did great job with plumbing system, sewage, connecting drainage system and making sure drainage running as planned with no blockage.

Due to the difficulty and risk involved for excavation, it was hard to find a contractor to take on the job but from my initial consult with Victor, him and his team noted their experience with these scenarios and he was confident they can do it in less than a day. On excavation day they brought the necessary equipment and tools and were very cautious about the gas pipe. They ended up finishing the job in less than a half day! To follow up, we realized we needed more excavation at the apron of the driveway and Victor again came to the rescue and excavated that for us a week later. I sincerely appreciate the time efficiency and skill that Victor and his team have in getting our excavation needs completed. I highly recommend Victor and his team and will always reach out to him first when we need more excavation for future projects. Thanks Victor!
