BID TITLE: Operation, Maintenance and Repairs for Heavy Vehicle Simulators (HVS)

OPENING DATE/TIME: October 31, 2023 at 2:00 pm (LOCAL TIME)

Notice is hereby given of the following changes to the above-referenced SOLICITATION:

• Questions and Answers provided below:

QUESTION 1

We understand that lighting strikes are a concern for the operation of the HVSs. Is there a plan in motion for the DOT to install a system to help mitigate this risk? In the case that it is still an unresolved issue, could the DOT provide a list of parts that most frequently are needed to repair damages due to lighting strikes?

ANSWER 1

While lightning strikes have historically been a problem and have damaged parts on both machines, we do not have any plans for the installation of other lightning-mitigating equipment. We do, however, turn off all equipment when we have nearby lightning strikes, and this appears to have mostly solved the issue. Both machines are equipped with grounding cables that attach to the shore power grounding rods, though these are only partially effective. The parts that have historically failed due to lightning strikes on the machines are as follows:

HVS Mk6: (Watlow RMAF-A3AB-AAAA, RMHF-11CC-AAAA, RMSF- RRJC-AAAA, RMLF-55JJ-AAAA) HVS Mk4: (National Instruments 9214 heater modules)

QUESTION 2

Please indicate what is the average duration for each experiment on each machine?

ANSWER 2

The average duration of HVS tests is as follows:

Rutting Test with Heaters at 50°C: Approximately 15 Days for the application of 100,000 HVS passes.

Cracking Test with Ambient Temperature 27°C to 35°C: Approximately 40 days for preconditioning the test section using the Accelerated Pavement Aging System (APAS) and 40 days for the application of 400,000 HVS passes.

QUESTION 3

Are the HVS monitoring technicians working full time in between experiments or only during the duration of an active experiment for any of both machines?

ANSWER 3

The HVS monitors are required to work during the duration of an active experiment for any of the HVS machines. The duration of the active experiment includes pre-conditioning of the test sections (Heating and APSA aging).

QUESTION 4

Are there any spare parts available to be used on the next operation, maintenance and repairs agreement? Could you please list those?

ANSWER 4 See the attached “HVS Parts List” below.

QUESTION 5

Is the DOT able and willing to store the inventory of spare parts that are needed to ensure the required optimal operation of the HVSs?

ANSWER 5

Yes, DOT allows storing spare parts under the following restrictions.

• The lead time of the spare part must be longer than 2 weeks.

• It is recommended the total annual cost for the part purchases (both HVS’s) cannot exceed 120% of the cost of the previous year.

QUESTION 6

Is there an established protocol for parts storage and inventory for the operations consultant to use and restock parts?

ANSWER 6

No documented protocol is available. DOT provides a 40 ft Shipping Container as the spare part storage.

QUESTION 7

Can the DOT provide a list of parts that are deemed discontinued or not available for the HVS Mk IV+?

ANSWER 7 HVS Mk 4 Drive wheel hydrostatic calzones, main hydraulic motor.

QUESTION 8

Is the HVS drive wheel motor the only part that is included in Exhibit A Section 2.4?

ANSWER 8

Yes, the HVS drive wheel motor is the only part that is included in Exhibit A section 2.4.

QUESTION 9

Are both HVSs operating 24/7 or is there a combination of operating hours and days?

ANSWER 9

Both HVSs should be operating 24/7. Delays due to the limited site conditions (test track construction, limited space, safety concerns, and limited power sources) can be excused from the operation hour calculation upon the project manager’s approval.

QUESTION 10

Exhibit A Section 6.7 indicates that work hours for all staff will not qualify for overtime, however on Section 3.3 it is stated that the on-site technicians need to monitor the HVS during holidays which is turn is included in the calculation of MPH. Can the DOT clarify if holidays are included as part of the expected HVS operations? If so, how can additional pay to the consultant staff be quantified?

ANSWER 10

The state holidays are taken by the HVS Chief operator and one or more of the HVS monitoring technicians will cover any absent shift. The HVS monitoring technicians are limited to 32 hours per week during standard non-holiday weeks. Coverage of the missing shift(s) during holidays are the only times the HVS monitoring technicians are allowed to go over 32 hours but not more than 40 hours. Work hours during holidays or more than 40 hours per week will not qualify for overtime.

QUESTION 11

It is our understanding that the consultant will be paid for network services to maintain and operate the HVSs. Can the DOT provide more information regarding what network services will be paid for?

ANSWER 11

There is an independent network used for the HVS operations. The current network provider is Star link satellite internet, which includes a wireless router as well. This network is required for the HVS(s) computers since TeamViewer is for fixing problems remotely.

QUESTION 12

Purchasing, inventory, shipping and receiving parts will require an admin support person to dedicate time to the project. Can Administrative Support be added to Exhibit C under Personnel Classification and Billing Rate table?

ANSWER 12

Purchasing, inventory, shipping, and receiving are currently performed by the HVS Chief Operator.

QUESTION 13

Can a column indicating the number of hours on the contract period be included in the table presented on Exhibit C in order to calculate the maximum amount of labor?

ANSWER 13

The vendor should only provide unit rates as specified in Exhibit C.

Additional information can be provided in a separate document.

QUESTION 14

It is our understanding that an allowance for needed spare parts cost is needed to be included as part of our response. Could you please indicate in which section of the proposal we will need to include this cost?

ANSWER 14

As part of Section C, Technical Plan, the Consultant should address an operation plan for the contract period. The operation plan should include staff/workforce management, long-lead parts inventory management, and preventive and corrective maintenance to satisfy the performance requirement of 60% Percent of Operation (PO).

QUESTION 15

Can the DOT provide a list of parts that are historically being used more frequently for maintenance and repair for each HVS?

ANSWER 15 See the attached “FREQUENTLY FAILED PARTS FOR HVS” list below.

QUESTION 16

Can the DOT allow a submittal due date extension in order for the consultants to obtain accurate and up-to-date pricing on needed parts for both HVS machines?

ANSWER 16

Considering the expiration date of the current contract, DOT does not allow any due date extension.
