The original base bid requirement for the project required the contractor to remove the following debris/sludge/grit material from the several structures including the existing Influent Lift Station,and had included an extra work item for additional grit solids removal. The contractor began removal of the contents of the existing lift station and encountered a much different material than expected.After several days of removal operations,the City was notified of this condition.The material was not grit but rather a grease material that would require enhanced removal and disposal techniques including more stringent safety equipment.The City elected to have the contractor continue with the grease removal operations and track the costs on a time and material basis to be assured of actual costs,due to this work effort being necessary and dependent on the Influent Lift Station work progressing on schedule.The changed condition at the existing lift station could have possibly been the result of the extreme flooding in Pearland due to Hurricane Harvey.The excessive amount of grease that was encountered was not anticipated by the City or Design Engineer at the time of design. The final summary of contents removed from the lift station and disposed of at the Republic landfill site: 49,880 Gallons Grease;45.46 Tons of Solids;28 Containers used during the removal operation.

The original base bid requirement for the project was for the contractor to remove the following debris/sludge/grit material from the following existing structures: 1. Existing Lift Station 10 tons 2. Existing SBR 115 tons 3. Existing ASHT 30 tons Total of 155 tons for the entire project. B. An extra debris/sludge/grit removal item #32 was also part of the contract. Total 60 tons. The contractor began removal of the contents of the existing lift station and encountered a much different material than expected. After several days of removal operations, the City was notified of this condition. The material was not grit but rather a grease material that would require enhanced removal and disposal techniques including more stringent safety equipment. The City elected to have the contractor continue with the grease removal operations and track the costs. The changed condition at the existing lift station could have possibly been the result of the extreme flooding in Pearland due to Hurricane Harvey. The excessive amount of grease that was encountered was not anticipated by the City or Design Engineer at the time of design. The brief summary of contents removed from the lift station and disposed of at the Republic landfill site: • 49,880 Gallons Grease • 45.46 Tons of Solids and • Total of 28 Containers used during this operation This changed condition dictated that the removal & disposal operation was to be accomplished on a T&M basis versus the originally planned base bid lump sum approach.
