BOULDER COUNTY LEFTHAND CANYON DRIVE

20401-0000 Roadway Excavation. Actual volume of excess material may vary, depending on the processing, sizing and placement of excess material in the available stockpile areas. The computed excess material volume assumes material is stockpiled at 95-percent density.

If imported materials are used for embankment or riprap, excess excavation volumes will increase.

Increases in excess excavation as a result of the Contractor’s discretion in material handling or utilization of import material will result in no increased cost to the Government.

Payment

204.17 Add the following:

Payment for Item 20401 is limited to ten percent of the plan quantity of excavation in the cut until the slope rounding in that cut is completed.

Section 205. – ROCK BLASTING

Description

205.01 Add the following:

Controlled pre-split blasting will be required for all excavated slopes where rock blasting is expected.

205.07 Add the following:

205.07 A test blast of up to 400 cubic yards (300 cubic meters) may be allowed with CO approval.

205.08 Delete the first sentence in fourth paragraph

205.08 (b) Add the following to the seventh paragraph:

Lifts may be offset 36 inches (900 millimeters) for drill clearance.

205.08 (b)(1) Delete first sentence

Measurement

205.11 Delete the text and substitute the following:

205.11 Measure the Section 205 items listed in the bid schedule according to Subsection 109.02 and the following as applicable:

Do not measure controlled blasting or production blast holes. Controlled and Production blasting is considered subsidiary to pay item 20401-0000 Roadway Excavation.

Payment

205.12 Add the following:

Amendment A003 October 14, 2015

E-35

Controlled blasting and production blasting is considered subsidiary to pay item 20401-0000 Roadway Excavation.

Section 251. — RIPRAP

Delete this section and substitute the following:

Description

251.01 This work consists of furnishing and placing riprap for bank protection, slope protection, drainage structures, and erosion control.

It is intended that rock excavated from the roadway prism will be conserved and used for pay items 25110-2800 Grouted Riprap, Method B, Class 8 and 25110-2800 Grouted Riprap, Method B, Class 8 (Bridge Foundation).

It is assumed that 15% grout by volume will be utilized for 25110-2800 Grouted Riprap, Method B, Class 8.

It is assumed that 25% grout by volume will be utilized for 25110-2800 Grouted Riprap, Method B, Class 8 (Bridge Foundation).

Geotextile filters are designated according to Table 714-1.

Material

251.02 Conform to the following Subsections:

Geotextile 714.01 Minor Concrete 601 Riprap 705.02

Construction Requirements

251.03 General. Perform the work under Section 209. Dress the slope to produce a smooth surface. If geotextile filter is required, place according to Section 207. Provide a concrete mix design for grouting that conforms to Section 601

251.04 Placed Riprap. Placed riprap is rock placed on a prepared surface to form a well-graded mass.

Place riprap to its full thickness in one operation to avoid displacing the underlying material. Do not place riprap material by methods that cause segregation or damage to the prepared surface. Place or rearrange individual rocks by mechanical or hand methods to obtain a dense uniform blanket with a reasonably smooth surface.

251.05 Keyed Riprap. Keyed riprap is rock placed on a prepared surface and set into place by impact pressure.

E-36

Place rock for keyed riprap according to Subsection 251.04. Set the riprap into place by exerting impact pressure with a hydraulic-powered bucket or an approximate 5000-pound (2000-kilogram) flat-faced mass.

Repeated impacts should be made until the rock is firmly seated and forms a reasonably uniform surface without reducing the effective sizes of the rocks. Do not use impact pressure on riprap below the water surface.

251.06 Grouted Riprap. Grouted riprap is rock placed or keyed on a prepared surface with the voids filled or partially filled with concrete grout.

Place rock for grouted riprap according to Subsection 251.04 or 251.05. Do not place concrete grout unless the air temperature is at or above 35 °F (1 °C) within the near-surface voids of the riprap. Place the grout in a manner to prevent segregation. Protect grout from freezing for at least 7 days after grouting.

251.07 Acceptance. See Table 251-1 for sampling, testing, and acceptance requirements.

Rock for riprap will be evaluated under Subsections 106.02 and 106.04. Perform acceptance testing for grading at stockpile at the source.

Concrete grout mix design will be evaluated under Section 601.

Material for concrete grout will be evaluated under Subsections 106.02 and 106.03.

Acceptance Method A riprap construction will be evaluated under Subsection 106.02.

Acceptance Method B riprap construction will be evaluated under Subsections 106.02 and 106.04.

Placing grout will be evaluated under Subsection 106.02.

Geotextile filters will be evaluated under Section 207.

Structure excavation and backfill will be evaluated under Section 209.

Measurement

251.08 Measure the Section 251 pay items listed in the bid schedule according to Subsection 109.02 and the following as applicable:

When measuring riprap by the cubic yard (cubic meter), measure in place.

Concrete grout will not be measured for payment and is considered subsidiary to 25110-2800 Grouted Riprap, Method B, Class 8 and 25110-2800 Grouted Riprap, Method B, Class 8 (Bridge Foundation).

Payment

251.09 The accepted quantities will be paid at the contract price per unit of measurement for the Section 251 pay items listed in the bid schedule. Payment will be full compensation for the work prescribed in this Section. See Subsection 109.05.
