Gentlemen:
On February 15,1974,Change Order No.1 was executed providing
for a special construction method andaddition?.!work to install
a portion of the subject contract behind the Gulf Coast liorrpital.
Prior to this construction unstable soil conditions wore also
encountered on the r.ranscov.b Tract and the special construction
iuetiiod v.ras used in this area.
When construction was begun behindGulf Coast Ho$?iial and across
'die East fork of C-ooso Creek,conventional construction r.othods
were used.However,after approximately tv/o weeks of construction,
during which constant observations were made of the installation,
a structural failure occurred between Saturday,June 29 and
Monday,July 1,during a period of high tide.Construction ceased
and an internal inspection of the pipo was made.Pipe was exam
ined and photographed for a distance of approximately 2400 foot
upstream from the damaged section including the special construc
tion on tho Brans comb Tract.No pipe upstream from the danced
section shoved any movement or structural failure.An attempt
was made to inspect a 360 foot,section of 36 inch gravity sewer
installed in October and November of 19 73 but this could not be
inspected internally as silt and mud had filled the pipe.
Change Order No.2,as recoranonded,establishes prices and quan
tities to complete the construction by the specialconstruction
method (established in Change Order No.1)behind Gulf Coast
Hospital,and to install 56-inch ductilo ironby the special

construction method in tho event the 36-inch in place,between
Gulf Coast Hospital and Spur 201,that could not be internally
inspected has been damaged or moved by unstable soil,
The contractor will clean tho 36-inch sever in place and an
internal inspection-will be made.Cleaning tho"lino will re
quire four to sixweeks.V,'c recommend that the contractor immedi
ately place on order the 24-inch ductile iron and the 36-inch
ductile iron as delivery tir.e on these itews is approximately 120
ydays.If the 36-inch pipe in place is satisfactory the 36-inch
ductile iron pipe order can he cancelled.Considering material
delivery time and construction tine,anticipated project comple
tion is March,1975.
The contractor has requested,and wo would rcconmend,a reduction
in retainac;C to 2%on all acceptable workwhich is not contingent
on Change Order No.2.iiov/over,so^e finish up and clean wo workjbUJJwillberequiredpriortoarecommendationforreductionin'rc-
