Wisconsin WisDOT Standard Specifications (within FDM) — Section 649

Effective with the December 2018 Letting 461 2019 Standard Spec ifications Section 649 Temporary Pavement Marking

649.1Description

(1)This section describes providing and removing temporary paveme nt marking.

649.2Materials

(1)Furnish pavement marking materials conforming to 646.2 .

649.3Construction

(1)Construct conforming to the following:

General mar king ............................................... ..................................................................................... 646.3.1.1 Long line ..................................................... ........................................................................................... 646.3.1.2 Removing ma rking .............................................. ................................................................................... 646.3.1.4

(2)Do not groove in temporary marking.

(3)Apply liquid marking and glass beads across the line at or exc eeding the following:

LIQUID MARKING THICKNESS BEAD APPLICATION

(mils)(pounds per gallon)

Paint 12 4 - 5 Epoxy 16 12 - 15

(4)If installing raised pavement mar kers at a new location, use n ew markers. If installing replacement

markers, the contractor may ins tall used markers in like-new co ndition.

(5)For pavements open to all traffi c, apply centerline and no-passing barrier line markings as follows:

- On intermediate layers, includi ng milled surfaces, on the same day the pavement i s placed or milled. - On the upper layer, on the sa me day the pavement is placed un less the contractor a pplies permanent marking on the same day the pavement is placed. - If weather conditions preclude same-day application, delineat e the travel lanes and provide no-passing signing as the engineer directs . Apply centerlines and no-passi ng barrier lines as soon as conditions allow. The engineer may restrict operations until these markings are c ompleted.

(6)If required to apply no passing zone temporary pavement markin g, reference the beginning and end of

existing no-passing barrier lines . Apply temporary no-passing b arrier lines at those existing locations. If the contract contains the Locating No-Passing Zones bid item , relocate permanent no-passing zones as specified in 648.

(7)Protect freshly applied paint marking until dry enough to prevent pickup under traffic. Replace

temporary marking, including ra ised markers, that deteriorates or fails to adhere to the extent that the roadway is not adequately delineated.

(8)Inspect and maintain temporary marking, including raised marke rs, as specified in 643.3.1(5) .

649.4Measurement

(1)The department will measure the EACH bid items under this section as each individual unit acceptably

completed and the LF bid items under this section by the linear foot of line acceptably completed.

649.5Payment

(1)The department will pay for measured quantities at the contrac t unit price under the following bid

items: ITEM NUMBER DESCRIPTION UNIT

649.0100 - 0299 Temporary Marking Line (material/type) (width) LF

649.0500 - 0599 Temporary Marking Arrow (material) EACH

649.0600 - 0699 Temporary Marking Word (material) EACH

649.0700 - 0799 Temporary Marki ng Raised Pavement Marker (type) EACH

649.0800 - 0899 Temporary Marki ng Stop Line (material) 18-Inch LF

649.0900 - 0959 Temporary Marking Diagonal (material) 12-Inch LF

60 - 0970 Temporary Marking Removable Mask Out Tape (widt h) LF

Revise 649.5(2) to restore language making temporary marking placed under the contractor's same day option incidental.

(2)Payment for the Temporary Marking bid items is full compensati on for providing the marking or

marker; for maintaining, and for removing the marking or marker . Placing and removing temporary markings applied under the 646 contractor option for same-day marking are incidental to the associated permanent pavement marking bid item.

Effective with the December 2018 Letting 462 2019 Standard Spec ifications Section 650 Construction Staking

650.1Description

(1)This section describes the cont ractor-performed construction staking required under individual contract

bid items to establish the horizontal and vertical position for the following: Storm sewer Subgrade Base Curb, gutter, and curb & gutter Pipe culver ts Structure layout Concrete pavement Concrete ba rrier Resurfacing reference Electrical installations Supple mental Control Slope Stakes Curb Ramps 650.2 (Vacant)

650.3Construction

650.3.1 General

(1)Department and contractor respon sibilities for construction st aking are specified in 105.6 . Conform to

105.6 and the additional requirements specified here in 650.3 for th e individual contractor-staking bid items the contract includes.

(2)Protect and preserve known prop erty and survey marks and land monuments as specified in 107.11.3 .

The contract may require related work under the 621 bid items.

(3)Obtain or calculate benchmark data, grades, and alignment from plan information. The engineer will

furnish data for the horizontal and vertical control points, co ntrol point ties, horizontal alignments, profiles, and elevations. Reestablish, set additional, and maintain the horizontal and vertical control points and control point ties, as needed for bid items. Furnish , set, reference, and maintain stakes and markings necessary to establish the alignment, location, benchmarks, elevations, and continuous profile-grades for road and stru cture work as needed for bid it ems. Supervise and coordinate construction staking.

(4)Check horizontal and vertical information including but not li mited to alignments, locations, elevations,

and dimensions, that either the pl ans show or the engineer prov ides, for compatibility with existing field conditions. Conduct similar compat ibility checks and accuracy checks of horizontal and vertical positions either the department o r the contractor establishes in the field.

(5)Perform survey work using conventional methods, or where the c ontract allows, GPS machine

guidance. The contractor may employ global positioning technolo gy, robotic total station systems, laser systems, conventional met hods, or other engineer-approved methods the engineer deems capable of achieving the specif ied horizontal and vertical tole rances for the work in question. Establish additional benchmarks and contro l points as necessary to suppor t the method of operation.

(6)Maintain neat, orderly, and comp lete survey notes, drawings, a nd computations used in establishing

the lines and grades. Make the su rvey notes and computations available to the engineer within 24 hours, upon request, as th e work progresses.

(7)Furnish surveying equipment, sta kes, flags, pins, lath, whiske rs, and other materials necessary to

perform this work, subject to the engineer’s approval. 650.3.2 Storm Sewer

(1)Set and maintain construction st akes or marks as necessary to achieve the required accuracy and to

support the method of operations . Locate pipe, inlet, catch bas in, manhole, and endwall construction stakes to within 0.02 feet horiz ontally and establish the elevations to within 0.01 feet vertically. Determine that the final elevati ons of storm sewer pipe outfalls and inlets match the existing field elevations, and provide this information to the engineer at a mutually agreed upon date or least 14 calendar days before ordering in lets, catch basins, manholes, endwalls, and storm sewer pipe. 650.3.3 Subgrade 650.3.3.1 General

(1)Under the Construction Staking Subgrade bid item the contracto r may substitute global positioning

system (GPS) machine guidance fo r conventional subgrade staking on all or part of the work. The engineer may require the contra ctor to revert to conventionals ubgrade staking methods for all or part of the work at any point during construction if, in the enginee r's opinion, the GPS machine guidance is producing unacceptable results. 650.3.3.2 Subgrade Staking

(1)Set construction stakes or ma rks at intervals of 100 feet, or more frequently, for rural sections and at

intervals of 50 feet, or more frequently, for urban sections. Include additional stakes at each cross-
