Project Overview

A. Bozeman Sourdough Water Transmission Main

a. All topsoil will need to be stripped from surface, stockpiled, and returned to existing

depths. All areas need to be restored to original condition and elevations.

F:\ADMIN\RPA STANDARDS\FORMS\PREBID AGENDA.doc Rev. 9/22

b. No rocks larger than 1 ½” left on the surface. Contractor required to reseed and

provide weed control for 2-year warranty period.

c. Fencing removal and replacement is required.

d. Traffic Control needs to be approved by Gallatin County.

e. Excavation/shoring/sheet piling/dewatering/creek bypass pumping for installation

of piping, valves, and blow offs.

f. Stay on public property or within 1957 easement (30’-0” wide) shown. The 1917

easement may not be used for this project. OSHA approved excavation is

required.

g. Existing 18” water mains shown are approximate in location. Any spoils or existing

piping or valves exposed during excavation will need to be removed and disposed

of by the contractor at no additional cost. There are two existing 18” lines in the

field currently which are abandoned on two separate easements. One of them is

on the same easement which the new 48” line will be placed, it is the contractor’s

responsibility to remove and dispose of any of the abandoned existing 18” which

conflicts with the installation of the new line. The existing 30” will remain in service

and it runs in Nash and Sourdough. Only the 1957 easement indicated on the

plans for placement of the new line is available for use. It was brought up by one of

the contractors that putting a 48” pipe in the middle of a 30’ wide easement is un-

constructible. The 30’ easement is all that is available from the city and if additional

work area is needed it is up to the contractor to work out his own deal with the

individual land owners.

h. Any bypass pumping of Nichols Creek around construction site is the contractor’s

responsibility. Pipe will be installed minimum of 5’-0” under creek. Line Nichols

Creek with bentonite soil mixture 2’-0” thick x width of trench per trench plug detail.

i. Megalug or approved restrained joint systems are required on all fittings. Concrete

thrust blocks shown must be installed in addition to restrained joints or megalugs.

j. Type II bedding is shown from Nichols Creek to the Sourdough tie-in per the

Geotech Report. Type I bedding is required under pipe to spring line.

k. Insulation is required on all pipe with less than 6’-6” of cover.

l. Trench plugs locations are shown on the drawings.

m. Utility markers are required at bends and valve in field and creek crossing. City to

supply markers and contractor will install.

n. Piping tie-ins to existing water at Nash & Sourdough is 30” Cement Coated/Lined

Steel Pipe. John Alston with the city shop said he has a pipe of the existing 30”

cement coated pipe in the yard if anyone would like to inspect it for size.

o. Maintenance of Flows, transmission main downtime without water, 8-hour max.

Eric said depending on the time of year more or less time may be available. If done

in the fall more time would probably be available.

p. Haul and dispose of native spoil material from site. Follow Gallatin County

requirements for hauling. Haul Roads - The Contractor must meet all City,

County, MDT, and Federal Regulations and Load requirements. During spring

thaw Nash Road and other county roads may not hold up to heavy haul trucks.

The County may impose stricter load restrictions during spring thaw or may not

allow any haul trucks to operate at all during the spring thaw time period. If Nash

Road or any other County road used as a haul route begins to fail, the contractor

will be responsible for all repair and project delay costs should they occur. Bidders

F:\ADMIN\RPA STANDARDS\FORMS\PREBID AGENDA.doc Rev. 9/22

shall contact the Gallatin County Road Department to satisfy themselves of any

constraints that may be placed on them that would affect the progress and cost of

the project. If needed the Contractor may apply for a project shut-down or later

start for the spring thaw time period. Chris said Bill Brownell is the contact for the

County.

q. Asphalt will be replaced in two 2” lifts.

Engineer's Cost Estimate - $2.1 Million

8. City of Bozeman Comments – Eric nor Bob and any comments.

Questions and Discussion

It was asked by one of the contractors – “Will flows be down in the fall, will that still be the case if

Pear is under construction”? Eric said yes and Limon will be down as well.

It was asked what cathodic protection we wanted? Chris said it will be answered in the addenda.

It was asked about the bonded joints in the piping, Does it need to be strap jumpered or wedges?

Chris said it either bonded straps or wedges could be used.

It was asked if fabricated tees for the blow offs would be accepted. Chris said they would be allowed

if done by an approved fitting supply company and they need to be submitted for approval in the

normal submittal process.

It was asked if the pipe was the same as that which was used on the last project by the treatment

plant. Yes, the pipe is the same.

It was asked if the new pipe could be offset in the easement to gain working room and Bob said no.

It was asked if the property owners were easy to work with – Bob said their dealings had been good

so far, the owner’s major concern was to get the restoration done correctly with not rocks left lying

around and no weeds. It was also asked if the spec for the reseeding was correct. Bob and Chris said

yes, they had a consultant review the seed spec.

It was asked if the hay would be cut before the project starts – Hay is normally cut in July and the

lead time for the pipe may be out past that. The city is responsible to pay the crop damage only on

the 30’ wide easement.

It was asked if there would be leniency on start time based on availability of materials – Yes.

Chris said that if the contractor puts together a deal with the property owners to use land outside the

easement they need to provide a copy of it in writing.

Chris will provide contact information in the addenda for the land owners.

Meeting was adjourned to the site for those who want to view it at 11:25.

10. Site Tour

Tie-in was discussed pointing out locate paint on pavement, existing valve box and blow-off.

One of the contractors asked if CDF (flowable fill) would be allowed for trench plugs. Flowable fill will

not me allowed in leu of bentonite trench plugs.
