2 6/10/2014 We’re seeking some information regarding the CAD file used for the grading design.

We typically pull this file into our quantity takeoff software, in order for us to better calculate our cuts & fills for the grading operation. It just makes the whole estimating process faster and more accurate. Anyway, I was hoping that you would release this file to the public for this exact use. Is this something I need to request through you, or should I contact the engineer direct?

NPS does not release CAD drawings in native format to bidders. These drawings may be pprovided upon contract award. All bidders have access to all drawings and Specifications in .pdf format only.

27 6/24/2014 The Specifications read all main line needs to be C900 PVC Pipe. This needs to be changed to SDR21 200# PVC for several reasons.

#1 Harco does not make a Ductile Iron Fitting for C900 PVC Pipe the just make DI Fittings for SDR21 200# PVC.

#2 C900 sizing stops at 4". There is a lot of main line piping on this project that is smaller than 4".

#3 No transition gaskets allowed. The only way you can go from C900 PVC to the smaller main line is by using transition gaskets.

C900 Main Line is changed to SDR21 Main Line in revised specs dated 6‐25‐14

#1 Agreed. Harco and LEEMCO do, however, make ‘transition gaskets’ for their ductile iron couplings and fittings, which should be used when connecting to existing ductile iron pipe. This is addressed in revised specs dated 6-25-14.

#2 The specifications (2.4, A, 1) describe C900 pipe in 4”-12” diameters. Any 3” pipe (mainline or lateral) would be gasketed SDR21 Class 200 PVC. This is addressed in revised specs dated 6-25-14, where now all new pipe will be SDR21 Class 200 PVC.

#3 Agreed; that statement will be omitted from the spec. This is addressed in revised specs dated 6-25-14.

C900 Main Line is changed to SDR21 Main Line in revised specs dated 6-25-14

29 6/23/2014 In the 29 page RFP_Proposal_Submission_Pkg document, section 4 of the template Small Business Subcontracting Plan notes an SB Plan flow down threshold of $500,000. FAR 52.219-9(d)(9), however, indicates an SB Plan flow down threshold of $650,000 ($1.5 million for construction of any public facility). These two thresholds conflict. Confirm the SB Plan flow down threshold is $650,000 ($1.5 million for construction of any public facility) pursuant to FAR 52.219-9(d)(9).

Confirmed. Update was made in Amendment No. 5.

41 6/30/2014 The 30” wide strip of paving at the base of the fixed security bollards is called out to be AC1 paving on L941. AC1 is an exposed aggregate pavement which will match the bike path pavement finish. Currently the existing 30” wide strip of paving at the bollards is broom finished concrete. The new exposed aggregate finish will not match the existing broom finish area where it ties together at bollards to remain. Should this new 30” wide strip be standard broom finish concrete to match the existing conditions?

The 30” wide strip shall be AC1 exposed aggregate pavement as specified

7/3/2014

42 6/30/2014 Sub-Factor E of the Technical Capability Section of the Technical Proposal asks us to identify subcontractors and their qualifications, personnel, etc., with our proposal. As it is not always feasible to get all of this information prior to bid submission, can we submit multiple possibilities and confirm upon project award?

You may list possibilites as requested. The review panel will review the qualifications of key-subcontractors. As stated in Sub-Factor E, Element 3 "Offeror whose proposed organization chart clearly identifies Key Personnel positions, lines of authority, and Key Subcontractors will be rated more favorably."

43 6/27/2014 I am looking at the erosion control plan and sheet C452 says matchline: see sheet C452. There is no C452 that I can find, page 71 is C451 and page 72 is C453?

The erosion and sediment control plan was originally prepared as a comprehensive plan for the entire arch grounds, which was later split with the associated contract areas. As a result, only sheets C450 and C451 apply to the Contract 2 project area, and sheet C452 was omitted from this package.

7/3/2014

44 6/27/2014 On drawing E301 they show lighting control system one-line, but on the electrical drawings they just call out for empty conduits with quazite boxes, I am not really sure what are the locations of the Lighting control system rack, and also all the devices that are being fed from HH-2G, HH2-c, HH2-E, HH2-b, HH2-D, and how many cables are going to each device?

52 6/30/2014 Detail 3 on sheet L941 for the fixed security bollard shows overexcavation for the grade beam and does not show the 6 feet of rock backfill for the “protected” side of the grade beam. Detail 3 on sheet S103 is reversed showing the 6 feet of rock backfill for the “protected” side of the grade beam but it does not show any rock under the grade beam. All of the various details and cross-sections on the structural plans are consistent and show the 6 feet of rock backfill and do not indicate any overexcavation of the grade beams. Addendum 1 of the soils report states “that fill remediation is not required below the bollard wall foundations.” Which details should take precedence in determining structural excavation and backfill for the grade beam associated with the fixed security bollards?
