POTENTIAL CHANGE ORBER TITLE: Natural Gas Emission Testing
CHANGE REASON: Client Request
POTENTIAL CHANGE ORDER DESCRIPTION: (The Contract Is Changed As Follows)
CE #049 - PCO 26- Natural Gas Emissia stin
Scope: Per RFI #63 and multiple site visits with NH DES, the DES has requested that we add a natural gas test to the overall emission testing protocol.
After further raview of the specs, it does not call out a test of 2 different gases on each engine, just blended gas. If the city would like to test on both gas
mixes (natural gas and blended gas) the added cost is broken out below. As a result of the extra day worlh of work, MC requests that 2 days is added to
the overall construction schedule, MG Labor includes sequencing from blended gas to natural gas throughout the duration of the emission test. See
attached CK Environemntal Breakdown. Please note we will not proceed with testing until the executive change order Is approved.
