Explanation
§ These contracts provide for pre-blasting surveys of nearby structures to document conditions before and after any blasting activities, and blast monitoring to ensure projects meet construction plans and specifications requirements.
§ During the construction of water and sanitary sewer projects, rock is sometimes discovered that impedes the progress of the project. At times, the only effective method for the removal of this rock is through blasting. When blasting is required, nearby structures can be affected by the seismic waves transmitted through the ground.
§ On October 22, 2018, the City issued a Request for Proposals (RFP); three proposals were received.
§ The companies selected best meet the City’s needs in terms of demonstrated competence and qualification of professional services in response to the RFP requirements.
§ Expenditures for all contracts are estimated to be $400,000 annually.
