The program shall include water analysis,chemicals,testing,equipment, <br />consulting and service for the following systems <br />B.Chemicals shall be suitable for pipe material,fluid medium,and intended treatment. <br />C.Provide initial chemical treatment and equipment for all systems based on complete system fluid <br />analysis including makeup water prior to installation. <br />D.Initial supply of chemicals for treatment of each system shall be sufficient for start up and testing <br />period,for the time the systems are operated by the Contractor for temporary heating and cooling, <br />and for one year after start-up of system. <br />1.07 STORAGE <br />A.Store materials and equipment raised off the floor on pallets and protected with coverings to <br />prevent damage due to weather and construction activities. Store in areas that prevent damage <br />due to freezing and extreme temperatures or sunlight. Arrange coverings to provide air circulation <br />to avoid damage from condensation or chemical build-up. Protect from damage,dirt and debris at <br />all times. <br />B.Store chemicals in curb protected area.Such secondary containment areas must have the <br />capacity to hold the volume of the largest container or 10%of the combined containers,whichever <br />larger. If room has no floor drains,then the room itself may be considered sufficient secondary <br />containment. If the room is considered the secondary containment ensure there is a lip at the door <br />so no liquids can exit the room in the event of a leak.Verify field conditions before storing any <br />chemicals <br />1.Provide temporary containment areas when permanent containment areas do not exist. <br />Remove temporary containment at the end of construction. <br />PART 2 PRODUCTS <br />2.01 MANUFACTURERS <br />A.AmSolv-Amrep,Inc​​ <br />Docusign Envelope ID: D4F3B98E-0756-4A0C-A3AD-05AA32D39F1C
