QUESTIONS & ANSWERS
Questions & Answers (Responses to RFIs received via email after Amendment 0008)
1. Amendment 0008, Section 01 11 04, para. 1.3.11.1 added language that states the intent is to use “standard bar joist or cold-formed metal roof spaced at approximately 4’ on center with metal deck, as indicated in Table C-5 Conventional Construction Parameters”. UFC 4-010-01, Table C-5 specifically states that only “K and LH joists with Metal Deck” are considered conventional construction. The use of cold-formed metal would require SBEDS analysis as added in Amendment 0007. Please clarify the use of K or LH joists
vs. cold-formed metal framing and applicability of UFC 4-010-01 Table C-5.
a. Please refer to Amendment 0009.
2. Amendment 0008, Section 01 11 01, para. 1.1.2 added the following “For bidding purposes, the measured standoff distance between the conceptual location of the CDC building and the installation perimeter is 494 feet per UFC 4-010-01 paragraph 3-2”. Please clarify if this should be the standoff distance used for UFC 4-010-01, para. B-2.1. The distances in para. 3-2 are not dependent on an explosive charge.
a. Bid as shown.
3. Amendment 0008, Section 01 11 01, para. 1.1.2 added the following “For bidding purposes, the measured standoff distance between the conceptual location of the CDC building and the installation perimeter is 494 feet per UFC 4-010-01 paragraph 3-2”. This contradicts drawings CS103 through CS106 which show a 75’ and 82’ setback per UFC 4-010-01 and FC 4-740-14F. Please clarify the setback distance.
4. Again, please confirm the distances that the ATFP cases in RFP Section 01 11 04, para. 1.3.11.1 are to be considered at: 75-feet/82-feet or 494-feet.
5. Per 01 42 00, 1.1 Order of Precedent, and paragraph 3.3.6 of 01 11 02, Lockers are not part of this contract. However, in Amendment 8, you indicate that the cost for the Staff Lockers should be included in Option 1. If you want something other than the design of the lockers included in this contract, you will need to change paragraphs 3.3.6 of 01 11 02 and paragraph 3-3.3.1.10 of the Facilities Criteria, which state respectively: “Lockers are not included in this contract” and “Lockers are considered to be non-RPIE and cannot be included as part of the MILCON contract.” Please reference Projnet questions 0933030 and 9821083 addressing this same issue.

1.1.5.5 Pavement Engineering and Traffic Estimates
1.1.5.5.1 Pavement Design
Pavement must be designed by the Contractor's Geotechnical Engineer to accommodate the design vehicle and the heaviest fire truck, which is 81,000 pounds. The Contractor's Geotechnical Report must contain flexible and rigid pavement design(s) including design CBR and modulus of subgrade reaction and the required compaction effort for subgrades. Information must be offered on the types of base course materials available in the area and design strengths. Pavement designs must be included in the report and should have a design life in accordance with UFC 4-740-14F.
Pavement designs shall be in accordance with UFC 3-250-01 dated 14 November 2016, which requires the use of PCASE software. Regardless of the pavement design, a minimum flexible pavement section shall consist of
3.5 inches of asphalt (1.5 inches of surface course and 2 inches of base course) and 8 inches of aggregate subbase and/or base. Regardless of the pavement design, a minimum rigid pavement section shall consist of 6 inches of concrete and 8 inches of aggregate subbase and/or base. The minimum subbase/base can be neglected if the subgrade has a CBR greater than 30 inches. For basis of rigid pavement design for bid, a CBR of 6 and a subgrade modulus of 100 pci have been estimated for this project.
SECTION 01 11 01 Page 14
Subsurface Drainage associated with pavements shall be in accordance with the UFC 3-250-01 dated 14 November 2016.
Plans and specifications shall detail all of the specific aggregates proposed in the pavement design per state DOT designations and gradations including the aggregate used to choke off drainage layer aggregates to accommodate paving equipment.
Pavement Designs must be in accordance with UFC 3-201-01 Civil Engineering, the latest version. The use of the Pavement-Transportation Computer Assisted Structural Engineering (PCASE) software is also an acceptable design method. The design must address seasonal frost conditions per State
DOT.
This paragraph is presented to warn the DB contractor of possible inappropriate results when evaluating binder grades for SuperPave designed pavements. It is USACE experience that binder grades for parking lots have been improperly chosen resulting in easily rutting unacceptable pavements.
The common characteristic has been that the state DOT standard specification was used resulting in the usage of lower grade binder. This is an inappropriate standard since the DOT recommended binder grades are intended for use in pavements with high speed traffic. It is highly recommended that the LTPPBind program (Located at https://infopave.fhwa.dot.gov/Tools/LTPPBindOnline) be used when determining the proper binder grade with the standard selections of Desired Reliability" = 98% and "Traffic Speed" = STANDING for parking lots, and SLOW for entrances, and low-traffic roads.
For bidding purposes, the contractor must perform their design of the pavement under the provisions of this RFP (as the basis for their bid) using a subgrade CBR value of 10% at 0.1 inch and the following traffic loading for a design service life of 20 years. Vehicle criteria and weight estimates for the planned pavements are assumptions. It is estimated that 50% of the POV vehicles will be trucks with gross weight of 5,500 lbs and 50% mid-size cars with gross weight of 3,000 lbs. The number of passes per day for the POV parking lots must be estimated utilizing the number of parking spaces and the percentage of vehicles expected to arrive and leave throughout the day. It is assumed 100% of the staff parking spaces will be occupied in the morning, 25% of the vehicles will leave for lunch, 25% of vehicles will return from lunch, and 100% of the vehicles will leave for the day. It is estimated that 4 passes per week for tandem axle trucks weighing 30,000 lbs (garbage trucks, delivery vehicles, etc.) will travel the entrance and service drive. It is estimated 4 passes per day for school buses through the entrance drive, the top lane of the staff parking and the bus loop. It is estimated 400 passes per day for POV through the parent loop and top lane of the staff parking. It is estimated that 2 passes each week through the entrance drive, the top lane of the staff parking and the bus loop for the heaviest fire truck of 81,000 lbs.
Should this design result in a pavement section less than the minimums required by applicable criteria, the contractor must bid the minimum.
During design, the Contractor must verify with the user the type of vehicles and pavement loading frequencies for the pavement design.
Subgrade conditions for pavement design (including design CBR value) must be verified by the contractor's geotechnical report.
1.1.5.6 Traffic Signage and Pavement Markings
Install stop signs at all parking lot exits onto adjacent streets. Erect
SECTION 01 11 01 Page 15 signs to designate handicapped accessible spaces, van accessible spaces.
Striping for parking lot spaces must be white. Provide a signage plan as part of the design submittals after award. For placement and appearance of all signs, comply with standards recommended in the latest edition of the Manual on Uniform Traffic Control Devices (MUTCD).
