PROJECT DETAILS: CO ER 43(1), Larimer County Road 43

The Government intends to use a competitively bid Single Award Task Order Contract (SATOC) with possible Construction Manager (CM) services integrated to perform repairs to Larimer County Road 43 caused by the September, 2013 floods. It is assumed that there will be a base or seed contract (Schedule A), and 3 Task Orders comprised of Option X, CM/GC Services, and Option Y. Schedule A focuses on roadway segments within US Forest Service (USFS) property, which is estimated to be 2.1 miles in length. Task Order 1 (Option X) and Task Order 3(Option Y) includes (8) drainage crossings and the structural section of the entire 10 mile project. Task Order 2 (CM/GC services) would be needed for constructability reviews of the remaining 7.9 miles of roadway, specifically the logistical approach for reconstruction and phasing.

Mile post reference within this report assumes Drake as mile post (MP) 0.0, Glen Haven as MP 7.8, and the end of project at West Creek as MP 10.0. No Work is planned for (MP10-MP15): this section of roadway is in good condition and no work is planned at this time.

SCHEDULE A- Base Contract (MP 3.9-4.4 & 5.8-7.4): Schedule A will include major roadway plan and profile reconstruction of 2.1 miles of roadway within USFS property. Major construction scope will include excavation, embankment, roadway cross drainage and armoring within the 2.1 mile segment. Additionally, production of aggregates, fill, and armoring material will be initiated during this phase from on-site excavated materials. These materials will be produced for this segment of road, as well as areas outside of the segment and within project boundaries. The preliminary construction estimate for this work is $9-13.0M. Major construction item quantities are as follows:
Item Quantity Comments
Excavation/rock cut 100,000 CY Avg. 20' shift in-board; Schedule A limits only.
Embankment 10,000 CY Schedule A limits only.
Pulverize 30,000 SY Pulverize existing 4-inch and re-use for temp surface and/or yellow top.
Aggregate Base (Production) 30,000 CY Assumes 6-inch section; volume for entire route
Riprap (Class 5) Grouted 20,000 CY Class to be verified; volume for Schedule A
Riprap (Class 5) (Production) 40,000 CY Class to be verified. Volume is total remaining for route; outside of Schedule A.
24-inch Pipe Culvert 5,000 LNFT Cross drainage every 500 LNFT of roadway; entire route
Clearing and Grubbing 20 ACRE Schedule A limits only.

Task Order 1 (OPTION X): - Drainage Crossings (8 Locations): A construction option advertised for pricing for (8) 18-foot span x 10-foot rise box culverts at 50 lineal feet each or 400 lineal feet total. Actual sizing will be confirmed through hydraulic analysis.

Task Order 2 (CM/GC Services): This option will be priced for the CM services only. CM services will be based on the anticipated major roadway plan and profile construction for all work not included in Schedule A. Major construction scope will include excavation, embankment, roadway cross drainage and armoring within for over 7.4 miles of roadway. It is the Government's expectation that the construction manager participates in alternatives evaluation and provides support on pricing in collaboration with the owner and designer. This will require involvement by key sub-consultants, suppliers, and other member of the contractor's team. The Government expects the CM to participate in the following tasks but not limited to: Review Project information; Attend Project Kick-off Meeting; Attend Necessary Filed Reviews; Provide Updated Documents Based on Field Reviews, Review Plans and Specifications as Part of all necessary Field Reviews and Provide Miscellaneous Design Support and Collaboration.

Task Order 3 (OPTION Y): - This option will be for construction pricing for surfacing of the entire 10 mile project. Major construction scope will include aggregate base placement and hot-mix asphalt. The preliminary construction estimate for this work is $7-9.0M. Major construction item quantities are as follows:
Item Quantity Comments
Aggregate Base (Placement) 30,000 CY
HACP 35,000 TON Assumes 4-inch section, 2 lifts
