(2) Unit cost of $64.91 is an average cost that is not fixed. Actual cost per conversion
will be determined by field conditions encountered at each meter location. Work includes
changing of meter box, adjusting meter box, installing an inverted riser, installing a riser,
changing out shut-off valve and installation of fittings.
Note : All quantities listed are best estimates at the time of the change order. Actual quantities
will be determined by field conditions encountered at each meter location.
(3)
Round meter pit lids
The standard process will be to take out the round meter pit, replace the water meter, convert the account
to AMR, reset the pre-existing round meter pit, perform any required infrastructure work, and replace
the metal lid with a 10.5" or 11.375" composite lid.
(4)
Special Pit Lid Solution # 2 - (non-traffic, non-road rated installation)
A 10.5" diameter hole would be cut to mount up to two MTUs underneath the composite lid. Around donut
frame will be welded to the underside of the mild steel lid to support a locking, RF transparent composite lid.
Incases where pits or vaults contain more than four meters, additional holes may need to be cut into the
metal lid.
(5)
Special Pit Lid Solution #3 - (road rated installation)
A 10.5" diameter hole would be cut to mount up to two MTUs underneath the composite lid. Around donut frame would
be welded to the underside of the mild steel lid to support the locking, RF transparent composite lid. An additional support
bracket will be welded on the underside of the metal lid in traffic areas to reinforce its structural integrity. In cases where
pits or vaults contain more than four meters, additional holes may need to be cut into the metal lid. Note that this is the same
solution as Solution #2 except for the added support bracket welded under the lid which has been proposed to add structural
integrity for traffic areas.
Additional Terms
During [he course of work in Corpus Christi, numerous meter pits have been identified with lids of odd sizes
and/or shapes that fall outside of the standard size lids and are to be addressed and priced separately.
Northrop Grumman is offering two (2) approaches for different scenarios [hat may be encountered in the Field.
Upon approval of these approaches, those meters that were skipped because no solution was previously
available will be revisited and completed with the appropriate approach. Going forward, the appropriate
approach will be employed as necessary.
The City shall be responsible for inspecting and approving all aspects of work performed by Northrop
Grumman to ensure it meets safety, reliability, and quality standards for the city. The City will notify Northrop
Grumman within thirty (30) calendar days of installation, as it relates to, any issues or defects foe immediate
correction, otherwise the implemented solution will be deemed accepted and City assumes responsibility.
Any additional labor, materials, and all costs that are required, outside of costs necessary to address supplier
defects, that were not originally contemplated by Northrop Grumman will be priced and presented [o the City
separately and are not contained in this change order.
Composite lid pricing for items 2, 3 & 4 above is dependent on the price of oil.
Should the barrel price of oil exceed $120.00 per barrel, Northrop Grumman reserve the right
to renegotiate pricing to reflect added cost of material content.
