Questions and Answers

Why is there no geotechnical sheets?

Will 4” durable tape be accepted in lieu of the specified 6” durable tape?

Where does the 4" sewer line go?

Does this need correction, the pipe going under Ky 122 is a 24" RCP not a 48" at the type C manhole?

In regards to the Asymmetrical Wall Section shown on Sheet 116 of the plans.  If the 14” width at the top of the Median Barrier Wall TY 14C MOD is maintained, will the owner allow the contractor to slope each side of the wall at the 10.8 degrees shown and eliminate the short vertical piece on the low side?  The wall will then be approximately 1.5” wider on the bottom of the low side.  It is assumed the contractor would cover the cost of the additional concrete and use this as an option to assist with constructability.  Note that this is only an issue in areas with a super-elevated curve.   

On page R145 it is stated that on NB & SB from the I-471/275 interchange to the south end of the project. work is to be completed when NKU is out of the spring and fall semester.  The I-275 interchange is very long, could a specific station be stated to determine how much work will be effected?

Regarding the island integral curb which is called for in several locations on the JPC Pavement Shoulders,  clarify what the overall width of the shoulders are when they have island integral curb.  An example of this is Memorial Parkway Ramp D.  The typical sections show Memorial Parkway Ramp D has a 6’ outside shoulder.  Sheet R71 calls out specific sections of this ramp that has island integral curb.  Where this curb is to be installed along the shoulders, is there 6’ including the integral curb, or is there 6’ plus the width of the integral curb (the curb is 7” wide).   Please also clarify if the pavement that the curb is attached to is paid to face of integral curb, or to back of integral curb. 

Do weekday holidays (July 4th on a Wednesday) count as a weekday in the “B” portion of the contract?

The pavement section for the permanent asphalt shoulder, phase 1,  in the JPC alternate is considerably thinner than the permanent asphalt section for the same shoulder in the asphalt alternate.  Is this correct? 

Will the Department please provide more detail concerning the maintenance of traffic pay items.  There are no details on when the temporary paint is used versus temporary tape.  There is no detail about the temporary pavement markers; are they used just in the transition areas or transition and tangent areas?  Please provide a breakdown of all maintenance of traffic items by each phase. 

Can the LandXML files be provided?

Should there be a pay item for removal of Raised pavement Markers Type V?

Does the prohibition of cold joints, per General Note for Final Surfacing on Plan Sheet R2g, apply to the outside shoulder?

Plan page R191 shows permanent paving being built at the north end of ramp A in phase 1.  This pavement is 4’-6’ wide.  There is a constructability issue here.  How will the cement stabilization equipment fit into this narrow area?

This job has a quantity of Asphalt Pave Milling & Texturing set up but the typical drawing doesn’t show it.  Is the quantity of 120 ton of  Asphalt Pave Milling & Texturing for edge keys? 

Regarding the General Note for Final Surfacing  on Plan Sheet R2g, how is a cold joint defined?

Please clarify the maintenance of traffic note on page 41 in the proposal. Will lane closures be allowed to complete the replacement of the finger expansion joints?

Are the time component unit prices correct as a fixed price?

Since a previous pre-bid question was answered that excavated material removed from job [concrete and dirt] could not be wasted on site, may recycled concrete be used for producing any aggregate required for project such as: Dense Graded Aggregate Base [DGA], Crushed Stone Base [CSB], JPC Pavement Drainage Blanket, and #57 Aggregate for Concrete?

On page 63 in the proposal, the last paragraph states that traffic shall be switched during night hours. The Southbound lane restriction will be scheduled by the hour with hourly penalties. Can traffic be switched at anytime? If not will the penalties stop until the nighttime hours? 

Why did the partial depth patching (bid item line no 0400) have such a large increase from the original project?  Can you explain where this quantity is anticipated to be used? 

How will inclement weather be handled with regard to the extremely excessive liquidated damages of up to $ 720,000 per day for any lane closure.  For example, on a week night lane closure from 7:00 pm to 5:00 am the milling-refill paving operation gets caught in a rain event that prevents the completion of that lane to be opened to traffic and work cannot be resumed for several days at $ 720,000.00 per day?

Please clarify the MOT requirements on Sheet R34 of plans for the work to be performed in Phase V, as well as the time allowed to complete Phase V.  Can contractor install asphalt plug joints during the entire months of August and September using lane restriction schedule shown in first column?  Phase V note states “contractor can only have lane closures from 12am-5am on the following dates: August 2-5, 2012 and August 16-26, 2012.”

For the Full Depth Replacement , should there be a pay item for “Relocate Temporary Concrete Barrier” and “Relocate Crash Cushion”?

There is a very large area south of I-275 between Northbound I-471 and Southbound I-471 where a concrete plant is currently located.  The concrete plant is located south of a crossing from SB I-471 to NB I-471.  There is approximately 8 acres south of this cross road.  There is an additional 8 acres north of this cross road.  We assume that the contractor for the I-471 project will be permitted to use the area north of the crossing for their concrete plant.  Is this correct?

In the special note for full depth concrete pavement repair (page 16 of 98  in the proposal ), section 2.1 JPC Pavement states that the concrete must achieve 3,000 PSI in accordance with Section 4.4 of this note. However, there is not section 4.4 of this note.  Please advise.

The proposal note for subgrade stabilization on sheet 172 of 321 specifies that a 48 hour curing period is required before constructing the aggregate base layer.  Within the areas of accelerated construction, where the contractor has 9 days or 16 days to complete all the work, virtually ¼ to ½ of the time will be used waiting on cure.  Will the Department modify the current special note for subgrade stabilization?

Since the diamond grinding is going to be eliminated, should the pavement markers also be eliminated?

The MOT typical sections for Phase IIIc (Middle Strip Closure – 3-Lane) imply that Phase IIIc must be completed during periods when only 1 lane of traffic per direction is allowed. Is this correct?

The Standard Specifications for 501 JPC Pavement, Base, and Shoulders does not address, nor prohibit, the use of a Dowel Bar Inserter [DBI] Machine.  If the contractor can demonstrate conformance to proper alignment, depth, spacing, and consolidation around the dowel bars, will the contractor be permitted to use a DBI machine? 

Is Asphalt Pavement Ride Quality specified for this project?

The work time restrictions shown on plan sheet R34 is difficult to understand because of all the am to am times.  Can this table be redone using 11:59 pm as the end of the day and 12:00 am as the beginning of the day?

Is the additional partial depth quantity intended to be used to cover the entire bridge deck surface area of the Kennedy Bridge with class m concrete, per note 3 on page 33?

Will the median barrier portion of the concrete median barrier box inlet modified shown on sheets R24 & R25 be paid as part of the bid item for the concrete median barrier box inlet items (Line No. 800 & 810) or will it be measured and paid as per Note 1 of Sheet R20 as part of Line No. 780, Single Slope Concrete Median Barrier-50?

Since the contractor is not permitted to do any work in the southbound lanes in 2012, is it correct that the contractor’s maintenance responsibilities will be limited to northbound lanes only in 2012, and southbound lanes only in 2013?

Plan sheet R2at includes a note on MAINTENANCE OF EXISTING PAVEMENT which states that current pavement maintenance costs are incidental to the Maintain and Control Traffic bid item. Because the scope of this work is completely unknown and could potentially be quite extensive, could there be separate pay items to cover these costs?

Should prevailing wages apply to this project? 

Is the existing concrete pavement that gets removed reinforced (mesh or rebar) or plain?

After doing a takeoff of the temporary concrete barrier wall, the sum of the quantities of bid items line nos. 1140 and 1410 seem low.  Has the Department taken in to account all of the barrier wall to close the ramp openings for the allowed closure times, opening the ramps after the closure times, and tapers in and out of the accelerated areas after completion?

The detail sheets for bridges B00052L (proposal pg 78) and B00052R (proposal pg 85) show installing new armored edges at both Abutments 1 and 2.  The installation of new armored edges at Abutment 1 seems to conflict with the notes for replacing the joint seals at each of these locations.  Please clarify if new armored edges are to be installed at Abutment 1 for each of these bridges.

Will the contractor be required to provide wrecker service on the Southbound lanes and ramps in 2012, and the Northbound lanes in 2013, since we will not be permitted to work in those areas during these time frames?

Bid item line nos. 2120 and 2130 are for the sealing of cracks on bridges B00056L and B00056R.  Additionally, Bid item line nos. 2140 and 2150 are for sealing the decks on bridges B00056L and B00056R.  Each of these items is set up on a lump sum basis.  Currently, the proposal states, “The approximate total length of cracks in 17,000 ft but the contractor is responsible for determining quantities for bidding.”  The proposal also states, “The approximate deck area to be cleaned and sealed is 225,000 sf but the contractor is responsible for determining quantities for bidding.”  With the size of the bridges and the heavy traffic crossing the bridges, it is infeasible for the contractor to field verify these quantities.  Will the department please change the units for each these items from lump sum to either linear feet or square feet? 

In section 606.03.17 of your specifications, Paragraph A, note 1 – “Pre-wetting and Grout-Bond Coat” requires a grout prior to the latex overlay placement.  This project requires the deck surface to be prepared using hydrodemolition and the area latex modified concrete suppliers are recommending the deck not be grouted, only pre-wetted prior to the overlay material.  Similar projects in Campbell County did not require this grouting procedure for decks prepared using hydrodemolition.  Will the grout bonding coat be required on this project prior to the placement of the latex modified concrete?

The Note for “Asphalt Pavement Drain” on Plan Sheet R32 states that the proposed locations are noted in the plans. However, I cannot find any reference to these in the plan sheets. Where will these be installed?

Is the contractor to paint only those bearings where the masonry plate is replaced?

Plan sheet R2, note 4, indicates that outside shoulders to be replaced during phase 1 will be bid per square yard and is to include all pavement and base layers necessary to construct the shoulder.  Plan sheet R2ag, Pavement Summary, seems to include either the Drainage Blanket or Crushed Stone Base under these Shoulders.  Is the base layer under the shoulder to be considered incidental to the shoulder or will the base layer be paid separately as either Crushed Stone Base or Drainage Blanket?

Because of the high traffic volume and complex phasing requirements on this project, there will be a significant need for Law Enforcement Officers (probably in excess of 1500 hours) to ensure the safety of the traveling public and our workforce while implementing permitted lane closures. Would KYTC please consider adding a separate pay item to cover Law Enforcement Officers and Patrol Cars?

Currently, the Class M concrete to be poured in the replacement sections for the expansion joint elimination and removal items shall be in accordance with section 601 of the Standard Specifications.  Will the Department allow the contractor to use a high early strength and/or fast set modified mix that will permit earlier removal of forms, and opening to traffic, provided the 28-day compressive strength requirements of Standard Specification Sections 601.03.14 and 601.03.15 are met?

The permanent striping on this project is being specified as Durable Waterborne and Thermoplastic Pavement Markings.  All striping contractors are required to purchase these Durable Striping Materials from a manufacturer that is on KYTC’s Approved Prequalified Material Supplier Lists, whose own internal specs., for proper application of these materials and even KYTC’s own “Section 714 – Durable Pavement Striping” specs., require a minimum air and pavement temperature of 50̊ before these materials can be applied.  Is it KYTC’s intent, as on similar past projects, to accelerate the Prime Contractor schedule even more in order to have the specified Durable Pavement Markings properly installed by mid to late October each year?  Will the Department consider applying temporary pavement markings through the winter for each construction season and then have the permanent Durable Markings installed the following year in late spring?

What type of material is to used for Bid Item 200, Backfilling Undercut?

Do the existing pier footings on I-275 bridge over three mile road bear on piling? 

Will plywood false decking be required to protect roadways beneath the hydrodemolition structures?

In reference to the temporary barrier wall for 12-1002, it was stated that, “The Cabinet will consider for approval the use of temporary barrier wall alternatives that are comparable to the performance of 9T wall (including deflection distances).”  Can you please provide the deflection distances and any other comparable performance requirements of the temporary barrier wall?

Please refer to plan page R145 the notes for Accelerated Construction in the middle column of the page. Specifically referring to the last & 3rd from last paragraphs, that talk about restrictions to traffic and lane closures in these areas. Contract work on span #8 is going to require a significant amount of under deck temporary access & safety work to prepare for joint removals and replacements plus cleaning of the lower chords of the arches. There is virtually no access under this span by any method other than working over the sides of the deck surface. If this preparatory work could be accomplished before & after the contract repair work to the deck surface (outside the 32 day time period allowed for each direction of traffic) by working with lane closures at night during period of minimal traffic there is a much greater chance the requested completion durations for accelerated construction on span #8 can be accomplished. Will the departments - both Ohio & Kentucky - allow nightly lane closures on & approaching span #8 so the preparatory work under the deck can be installed & removed outside of the 32 day accelerated time period for each direction of travel?  

Note 6 on sheet T04 states that “All existing sheeting signs…are to be removed… and replaced, as shown on the signing plans, unless otherwise specified.”  This note continues to state “In addition to replacing all existing signs, all signs shown on the signing plans must be installed.”  This note appears to contradict itself, as the first sentence refers to the 5 sheeting signs shown on sheet T22, however, it continues to say replace all the signs as well as the signs shown on sheet T22.  Also on sheet T04, notes 3, 4 and 11 put additional constraints on what signs should or should not be disturbed, removed, and/or replaced, further complicating the interpretation of note 6.  Will all sheeting signs on the project need to be replaced, as constrained by notes 3, 4, and 11, regardless of whether they are shown on the plans?  If so, what are the limits for sign replacement?  For example, if a sign is in the median, but the only work being performed on the road is on the outside shoulder (as is the case on I-275) will the median sign need to be replaced?  Because the interpretation of this could be quite open ended, please supply a list of all signs with quantities, final disposition, and method of payment for this project.

Plan sheet R2at includes a note on CEMENT STABILIZED ROADBED which requires the top 12 inches of the roadbed to be stabilized with Portland cement using “selected soils with a minimum CBR value of 2”.  In the event existing in-situ soils have a CBR value less than 2,  will the contractor be required to remove and replace this material? If so, where does the contractor get paid for removal and replacement? Also, is the contractor required to test the soil for CBR values, and if so who is responsible for testing costs?

In response to the answer for the question concerning southbound single lane restriction traffic switch during daytime hours, if the bidders schedule for the project has the projected traffic switch occurring during peak hours and the state delays switching traffic until the off peak hours should the contractor allow for these extra hours in the C portion of the bid?

Is it possible to arrange with District 5 to get a lane closure prior to bid to get a closer look at median barrier wall removal and the drainage boxes under the median wall?

The widening of I-275 bridge over three mile road will require removal of portions of the barrier wall and curb & gutter due to pier footer excavation.  There is a note on Sheet No. S3 Dwg No. 26788 that says “Existing roadway curbs & pavement are to be protected from any damage during construction of this project.”  Is the work to remove and re-build the wall, curb and gutter incidental to the excavation?

The proposal for bridges 13 & 14 call for new 5.5" expansion joints to be installed in the decks at pier #6. The existing bridge plans indicate the existing joints at pier #6 are modular joints supported by significant steel components. It appears these modular joints will need to be removed entirely to allow the new joints to be installed. Is it going to be possible to install the new 5.5" joints as detailed on pages 153 & 163 of the proposal without modifying the structural support steel below to properly provide support for the new deck and joint as specified?

Does the Bid Bond amount have to be 5% of the total bid including A+B or does it have to be just the A component?

On page 12 of the proposal for the above referenced project, it states that if utilities are required to be relocated/adjusted it is the responsibility of the contractor.  It is common that we would have to coordinate with the utility companies for them to do their relocations. However, it is uncommon that we would have the pay the utility company to perform a relocation.   Can you clarify which party will be  responsible for paying the utility companies if it necessary to relocate utilities, the Contractor or KYTC?

If the contractor chooses to construct the cement stabilized JPC Pavement Drainage Blanket, how will the Department pay for this item?  Will you measure the area placed and use the factor of 100 lb/sy-in to calculate the tons to be paid?  

If ambient weather conditions prevent the installation of the markings prior to the December completion date, and the contractor installs the final pavement markings during “non-peak” hours once weather permits, will the contractor be charged disincentive fees for work beyond the days bid during the installation of the permanent markings?

Supplemental specification 105.12 states the payment for electrical service is the contractors responsibility.  Is the Department’s intent to have the contractor pay the bills for the newly installed electrical service?  If so, can you provide the cost history of the existing lighting, so we can determine what to put in the bid?

On Page 11 of the proposal, the bituminous asphalt specified is CL4 ASPH SURF 0.38A PG76-22.  Is this the mix that should be specified for 50 foot and 100 foot patches on bridge ends on rural roads that have CL2 ASPH SURF 0.38D PG64-22 currently adjacent to the bridges?

In response to Addendum #4, regarding the new note on Acceleration Construction, are we correct in our assumption that the contractor will be charged a maximum of one (1) B day per calendar day on the project? In other words, if a contractor has traffic restricted to two (2) lanes between 85+00 and the Ohio River, and at the same time he also has a 2-lane restriction in one of the mainline Acceleration Construction areas, will the contractor be charged one (1) B day or two (2) B days?

For bid item line no. 0130, item 06427, the description is “Trenching”. What does the work for this item consist of?

Sheet R41J indicates that if footings are embedded into rock 2' no  paved flowline is necessary.  However, it appears from the geotechnical notes that rock on a good portion of the eastern footing is several feet below footer elevation.  There are options to extend to bedrock below the culvert footer using granular material or mass concrete.  If one of these options is used, does one have to install the paved flowline for the width of the culvert?  If so, that means the rock (>10') on the western side will have to be excavated to allow construction of the flowline as well as much of the existing stream bank on the eastern side, and in the steam also.  Assuming that to be correct, will the rock removed be paid as Structural Excavation - Solid Rock or will it be part of Foundation Preparation?  If the granular material or mass concrete is extended to 2' below top of rock does that mean the flowline will not have to be paved?  If the flowline does not have to be paved, what about the removal of the material inside the barrel of the culvert?  Is it paid as Structural Excavation - Solid Rock or will it be part of Foundation Preparation?  Or can it be left in place?  If the footers are keyed into rock 2' (or it's allowable to extend the granular material or mass concrete 2' into rock) and the flowline paving is not required and the material inside the barrel is left, will the Department pay for removal of the rock necessary (especially on the western side) to set the 3-sided structure as it appears that more rock will have to be removed to install the structure than is necessary to construct the footers (it appears that the haunch of the structure could be partially in solid rock)? If it will be paid, will it be paid as Structure Excavation – Solid Rock or will it be part of Foundation Preparation?

It is noted that a disincentive amount of $100,000 per hour shall be assessed in quarter hour intervals for any time after the 6 am that all lanes are not open to traffic. The amount of the disincentive is substantial.  Is this dollar amount correct?

Are all service drops limited to 35 Ft Wooden Pole the service & control cabinet is on? (Meaning- there is no long runs and or extension to bring power feeders to this 35 Ft Wooden Pole?)

With having to clear for utilities drops as stated in proposal, would this call for a bid item, “CLEAR & GRUBBING”?

These questions are for Line 0140 Item 04899 Electrical Service 20 each and Line 0150 04901 Telephone Service 20 each. In the Material, Installation, and Bid Item Notes for Permanent Traffic Data Acquisition Stations portion of the proposal; section 3.5 Electrical Service paragraph 3 it indicates that “Contractor shall obtain electrical inspections, memberships, meter base, service disconnect and any other requirements by the utility serving the installation and pay all fees as required.” section 4.3 Electrical Service indicates that “Electrical Service shall include furnishing and installing all necessary materials and payment of all fees toward the complete installation of an electrical service which has passed all required inspections.” section 4.16 Telephone Service indicates that “Telephone Services shall include furnishing and installing all necessary materials and payment of all fees toward the complete installation of a telephone service, which has passed all required inspections.” Are the charges from the individual utility companies for their portions of work billed to and paid for by the state or are these charges included under the umbrella of “fees” as mentioned in the above paragraph? If these charges are included as “fees” does the state have a listing of the individual utilities and contacts for each of the locations so that contractors can contact them for the cost of their services?

Typically, when there are 35Ft-Wooden Poles as a Bid Unit, there is always a call for “ANCHOR GUYS” or “ANCHORS”. Would this bid item be added?

Section 3.9 and 4.6 refer to Install Pad Mount Enclosure but the Figure sheets do not show pad mounted enclosures. If these are used, where are they being used?

Concerning Items: Signs, Arrow Panel, Portable CMS & Truck Mounted Attenuator, the quantities for these items appear to be set up for working one location at a time.

Will LWC be furnishing the pre-stressed concrete transition fittings for connection to existing concrete water mains?

Can the contractor use Life Rings attached to life lines in lieu of a skiff due to no boat ramp, low summer water levels, and the fact that the stream is not monitored regularly by the Coast Guard, and low height from deck to water level? Also the lack of Navigation Lights on the structure indicates this may not be a navigable waterway.

On pg. 159 (ITS-20), it is stated that “The initial evaluation should include micro-simulation (VISSIM) of the selected system. The micro-simulation should utilize a “hardware-in-the-loop” or similar system.” Does the micro-simulation specified in the RFP include construction of the original VISSIM file in addition to running the simulation and measuring the results?

What amount of funding is designated for the adaptive portion of this project?

On pg. 161 (ITS-22), it is stated that “The system shall be compatible with the existing local controller hardware/firmware and the KYTC’s TransPHAT system along with Louisville Jefferson County Metro Government’s Advanced Traffic Management System (CENTRACS). The reconstructed traffic signals will continue to operate with TransPHAT and it is envisioned that this group of signals will eventually be under CENTRACS control and monitoring.” Do the intersections have separate system detectors aside from vehicle detectors so that the CENTRACS system can operate side-by-side and still be able to monitor all operations?

In light of the issue concerning Electrical and Telephone "fees", would the Department consider letting this project at a later date to allow sufficient time to investigate and consult with the individual utility companies involved?

At which of the five intersections (if any) is Jefferson County currently using or planning to use in the next 12 months emergency vehicle preemption (EVP), transit system priority (TSP), or any other form of preemption or signal priority?

Please clarify the identity of the “system provider” and “system supplier” mentioned beginning on page 158 (ITS–19). Specifically, is the prime contractor or the adaptive traffic signal system provider responsible for the adaptive micro-simulation and before-and-after study?

In how many instances will there be a cable run greater than 320 feet between the traffic cabinet and a camera at that same intersection?

On pg. 161 (ITS-22), it is stated that “The system shall be compatible with the existing local controller hardware/firmware and the KYTC’s TransPHAT system along with Louisville Jefferson County Metro Government’s Advanced Traffic Management System (CENTRACS).

The proposal states that “The system shall provide capability for the operator to establish a manual override function for signal changes or to revert to programmed time-of-day and day-of-week schedules programmed into the local controller.” It also states, “The system should have the ability to run a fixed time of day pattern if necessary.”  InSync works by placing detector calls into the controller which is in free mode. The controller recognizes InSync as a detection system. InSync only submits detector calls for up to one pair of concurrently permissible phases. In this way, the controller does exactly what InSync wants it to do. In order for the controller to run its programmed timing plans, it of course must stop running in free mode. The way to remotely command the controller to stop running in free mode and start running its coordination plans is by associating such a command with a configurable 24V pin. What this means is when that 24V pin is actuated, the controller ceases running free and instead runs its programmed plans. Does the existing firmware allow a command like this to be associated with a 24V input/output pin? is there at least one free pin available for this function?

Would it be possible to use the State Certified material,  Crafco Poly-Fiber Type 3 for this project?

The above referenced bid is out for an Adaptive control system to be installed at 5 new controllers along Hurstbourne Pkwy. The specification requires us to use the 170E controller with WAPITI software. Econolite has an Adaptive module for Centracs that interfaces directly with an ASC3 (NEMA, 2070 or rackmount) controller. The Adaptive module does not interface with WAPITI.  Would the Department consider a proposal from PMI and Econolite that would replace the 170 controllers with an ASC3 Rackmount  controller or 2070 with ASC3 Software with full adaptive capabilities?
