Per Section 409.10 Application requires the surface to be fog with water in front of the spreader. To require the surface to be fogged with water in front of the spreader could have an adverse effect on the material and not necessary in certain applications. I would suggest changing the wording to when needed.

SCR section 703 aggregate page G-3.

Use only one type if aggregate on the surface treatment.

Use either OKDOT or TXDOT material specification regardless of the park location in Oklahoma or Texas.

Please clarify the following.

-Is this SCR for this RFP require using one or the other aggregate specified for the surface treatment per park location or the entire project

-The OKDOT and TXDOT specifications do not coincide with the specifications on page G-3 (a) or (b).

-Gradation table 703-5-page G-4, the grading designations do not line up with OKDOT or TXDOT gradation specifications and grading C on this table indicates No. 200-sieve specification is 1.0 to 1.0.

-TXDOT gradation table does not specify a 200-sieve gradation for chip seal aggregate. OKDOT has a 200 sieve that is 0.0 to 2.0.

-OKDOT specification does not contain AASHTO T 104 sodium soundness test.

-TXDOT specification does not contain flat & elongated particles, but a flakiness index, soundness test is magnesium sulfate, not sodium soundness, does not contain an AASHTO T 112 test. A Tex-460-A part I for angularity not ASTM D5821

Contractor may utilize aggregates meeting

TXDOT specifications, ODOT specifications or FP-24 Section 703 Specifications per park location –

It is confusing to request aggregate prices from suppliers that mix and match specifications from FP-24 and local

DOT specifications. To eliminate this the specification for the scrub seal and chip seal aggregate should be either

OKDOT or TXDOT specification as it is written in their standard specifications or the FHWA FP-24 specification type 1C.

Intent is to provide some flexibility to contractors and suppliers to match local supply processes and material availability.

Contractor may utilize aggregates meeting

TXDOT specifications, ODOT specifications or FP-24 Section 703 Specifications.

Contractor must use the same material at each park

Section 153 – Contractor Quality Control Page E-30 Please clarify the following.

-Since this project is in two states and four locations, does this specification require a separate QCM in each state and in each location. Will one (1) QCM for the entire project meet the requirement in FP-24 & the SCR of this task order or will the contractor be required to have two (2) QCM in each state.

-Will a separate QCM technician be required at each location to inspect every phase of work separately, (crack seal, HMA, FDR, chip seal, fog seal, micro surfacing) etc., meaning three phases of work are going on in the same park, how many QCM technicians will be required to satisfy this specification.

Per subsection 153.01 a QCM will be required to “ensure work conforms to the contract requirements”. The contractor’s schedule and phasing of work will dictate how many QCM’s are required. Also see subsection 153.03.

Section 635 Temporary Traffic Control

Will the contractor be paid for two (2) separate traffic control supervisors when working in two separate locations or states and will one traffic control supervisor be sufficient working in one area with multiple phases of work being constructed at the same time? Will this require more than one traffic control supervisor and if so, will the contractor be paid for two traffic supervisors or only one based on this scenario.

A TCS will be required to cover every phase of work requiring traffic control. The contractor’s schedule and phasing of work will dictate how many TCS’s are required.

When work requires active Traffic Control and the presence of a qualified Traffic

Control Supervisor in separate parks, each

TCS will be paid per day. See 635.24.

In Lake Meredith, the preparation prior to placing the surface treatment will require a tremendous amount of sweeping, cleaning and removing vegetation etc. Please clarify the following.

1. Is the contractor required to remove the overgrown vegetation from the shoulder of the roadway that will interfere with the application of the surface treatment on the edge of the asphalt or will the park clean the shoulders prior to surface treatment.

2. There is going to be a large amount of loose aggregate that will need to be swept up prior to additional cleaning required. Can the existing aggregate be swept to the shoulders of the roadway and left as shoulder dressings or will this need to be vacuum broomed and disposed of. If this issue requires vacuum sweeping and disposal, does each park location have a site within the park to dispose of or will this need to be hauled of site and disposed of outside the park boundaries.

3. Will the cracks on the scrub seal roadways need to be cleaned with air, water or other method prior to placing surface treatment or will sweeping the existing surface only be sufficient.

1. Trimming of overhanging vegetation that interferes with the application of the surface treatment is the responsibility of the park.

2. See Section 407.06 and 409.07. Vacuum sweepers and disposal of waste materials offsite is required.

3. Vacuum sweeping is sufficient to clean roads with a scrub seal surface treatment.

Numerous parking areas throughout this project have parking stops in the parking lots. The surfacing tabulations identify situations where some of these wheel stops are to be removed and replaced with new stops, while others state to remove and rest the wheel stops. Some parking areas don’t identify what to do with the existing wheel stops. Examples of these areas are WABA 0900 and CHIC

0914. Please clarify quantities and how the wheel stops are to be handled in areas not identified on the plans?

In routes where wheel stops are not identified in Remarks to “Remove and place new wheel stops”, or “Remove and reset wheel stops”, the contractor can place surfacing around existing wheel stops that are encountered.
