Efficient Solutions

Because Duro-Last holds the contract with TIPS, authorized contractors work directly with Duro-Last to develop and submit comprehensive proposals for consideration. Public agencies save significant time and money by accessing a contract that has been awarded by a lead government agency. The ability to purchase direct off of a contract saves many of the costs associated with the traditional bid process.
