INVITATION TO BID
The Confederated Tribes of Grand Ronde (CTGR/owner) hereby extends an
invitation to general contractors to bid on the Route 312 Culvert Replacement
Project in Grand Ronde, Oregon.
Project Description
The Route 312 Culvert Replacement Project includes construction on Route
312 and Yoncalla Creek, and replacement of an existing culvert in Yoncalla
Creek, located in Grand Ronde, Oregon. Route 312 and Yoncalla Creek Road
are located in the timberlands of the Confederated Tribes of Grand Ronde.
Route 312 takes off from Yoncalla Creek Road and crosses Yoncalla Creek.
The Yoncalla Creek crossing consists of a corrugated metal pipe culvert that
stands in a crushed arch-pipe confi guration. This pipe is inadequately sized
and positioned to accommodate fi sh passage in Yoncalla Creek and is in dan-
ger of eroding away the roadway if not addressed.
The Route 312 Culvert Replacement Project will involve widening Yoncalla
Creek at the crossing and replacing the existing culvert with a larger, bottom-
less arch confi guration. In addition, a gravel overlay of the existing road will be
included in the project.
Construction proposed by the owner will include:
1. Mobilization and staging.
2. Construct, maintain and remove temporary work zone traffi c control mea-
sures.
3. Construct, maintain and remove erosion control measures.
4. Perform all removal of structures and obstruction, clearing and grubbing,
and earthwork operations.
5. Installation of new creek crossing structures including, but not limited to,
footings and culvert pipe materials. Culvert pipe materials will be provided by
owner and installed by contractor.
6. Construct roadway improvements including, but not limited to, aggregate
subbase and base, gravel wearing surfaces and gravel shoulders.
7. Roadside development including armored slopes, seeding and planting.
8. Follow all permit and funding requirements.
All associated information required to complete the construction are described
in the construction drawings and these contract documents.
