8. Tie-down Anchors 16. Adjust asphalt quantities

and cost
to balance contract The reasons

for the changes ordered

are as fOllows: 

### l. The additional dtilling depth was required

to achieve

the required embedment depth
of 12'-6''

in native soil
as shown

on the plans. The additional drilling depth in native soil was dctctmincd

by the geotechnical inspector based
on the logs and observation

of the drilling operation. 2. The AC pavement

in the aircraft service area was low
in some spots and needed

to be repaired

to provide

a smooth grade transition prior

to applicatio11

of slurry seal. 3. The iJTigation lines were located where
the foundation

of the blast wall would

be constructed

and had to be relocated. 4. The drilling

of the foundation
piles had
to be stopped while the conduit
and electric wires were identified

and tagged
for ruturc repair. 5. The location

of aircraft tie-downs
next
to the hangars

on the soLtth apron shown

on the plan did not match field dimensions

and bad
to be revised. 6. 14 tie-downs needed

to be relocated because

of taxiway clearance requirements, which were not identified before
the tic-downs were installed.
The abandoned

**tic~** down cups had to be filled

to provide

a smooth surface

for application

of slurry seal. 7. The ·width
of the foundation

as shown

on the plan did not provide room for the anchor bolts and the concrete wall. 8. The existing ta-xiway striping

in the south tie-down
area was
in conflict with the new tie-down layout and taxiway striping. The conflicting striping was removed using

a wet sandblasting method.IllIllIll0HDIIIIDDDDDDD1II]9.Airportmanagementrequested12additionaltie-downsintheconcreteareasouthofAirportAvenueduetotheshortageoftic-downstalls.SinceBidItem8.TiedownAnchorsdidnotspecifyconcretecoringforinstallationthiswasconsideredextraworkandwasdoneontimeandmaterial.10.Numberingoftheaircrafttic-downstallswasnotspecifiedintheoriginalcontract.ThestripingSLJb-contractorproYidedareasonablecost,andAirportmanagementauthori£edthisadditionalwork.II.Theirrigationcontrollerconduitandwiringwasnotmarkedinthefieldorshownontheplans.Theyweredamagedduringthedrillingoperationandneededtoberepaired.12.Additionalstripingwasnecessarytoprovideaircraftaccesstosomeofthenewlyinstalledaircraftstalls,andtotheHelipadarea,whichwasaddedtotheslurrysealwork.13.Airportmanagementelectedtoprovidethechainsandhooks.TheContractorwasrequestedtoprovideacreditforthisdeletedrequirement.14,ARHMisnotsuitableforapplicationinlayersof1"orless.Partofthepavementrehabilitationinvolvedcompletereconstructionornewconstntctionofthefullasphaltpavementsection.Bothapplicationswerebettersuitedtoconventionalasphaltinstallation.TheContractorwasrequestedtopro\·idcacreditforswitchingtoconventionalasphalt.15.The<:1djustmcntstobiditemsreflectthechangebetweenbidquantitiesandactualmaterialquantitiesmeasuredinthefieldandnecessitatedbytheproject16.ARHMcostadjustmentwastobalancethecontractTheatljustcdcostwasincludedunderaseparatepavingcontract.ThischangeorderincreasedtheconstructioncontractamountbyS100.684.70ofwhich524,503.70waschargedtooffsiteworkduetothelimitedcontingencyamount.ConstructionManagementContractChangeOrderNo.1ConstructionManagementContractChangeOrderNo.1wasissuedtoprovideadditionalinspection,constmctionmanagement,andcoordinationservicesassociatedwithincreaseinscopeanddesignmodificationstotheconstructioncontract.Specifically,thefollowingchangeswereordered:1.Pro\·idcadditionalinspection,constructionmanagement,andcoordinationservicesassociatedwithincreaseinscopeandwith necessarydesignmodificationstotheconstructioncontract

The reasons

for the changes ordered
arc as follows: 

### 1. Additional services were needed

to coordinate changes

to the drilling
and construction

of blast wall foundation, modify
the anchor plate design, provide layout plan for the installation

of aircraft tie-downs,

and revisions

1 

### adjustments

to stripping layout

to accommodate

field conditions. This change order increased

the construction management contract amount

by 

### 55,000. 

### SuMMARY

OF CONTRACT ITD'IS This project \vas accomplished
under

a unit price contract with pay quantities measured

in

an inspection program

at the Airp011

to monitor pavement conditions.
Any damage

or defects, which show up, should

be promptly repaired. 2. Implement

a weed suppression

and abatement program

in the aircraft tie.down 

### areas. 3. Develop

a GIS
to manage aircraft tic-down leases and co-ordinate temporary relocations during constmction projects

as necessary

. 

### 4. Monitor surface drainage around
the blast wall fot1ndation

lo identify
and correct 

### potential problems. Submitted
