RFI QUESTIONS AND ANSWERS

W911SG-18-R-ARROYO

RFI QUESTIONS AND ANSWERS

1. Are surface mount guardrails being specified? No, install guardrails as per NMDOT Standard Drawing 606-GR31-16/20, “Drainage Structure Protection System” with W-beam guardrail attached to parapet wall of headwall when above culvert.

2. Is there a more detailed drawing on the waterbars? Water bar detail on sheet 4 and called for in specification Section 33 40 00, 2.2.2.

3. Is there a more in depth on the Guardrail install? Install guardrails as per NMDOT Standard Drawing 606-GR31-16/20, “Drainage Structure Protection System” with W-beam guardrail attached to parapet wall of headwall when above culvert.

4. Due to there being multiple projects bidding at the same time from multiple KO’s and some of them are due on the same day and will possibly be starting at the same time. If a contractor is awarded multiple projects will that contractor be able to stagger the contracts for their available construction crews?? When you are submitting bids/ proposals on multiple projects you are assuming the risk at that point.

5. On the plan sheets the box culvert dimensions do not seem accurate with what is shown on the plan view, cross section and the call out for the New Mexico Standard Drawings 511-2 series. On sheet 4 of the plans, the plan view calls out for a distance of 30’ for the overall width of the proposed culverts. This is not accurate as the clear span on each proposed culvert is 6’, without including wall thickness, this puts the overall width at 36’. With the 7” wall thickness, it should be 40’ – 1”. Is this what is intended? Yes, this was a typo, drawing sheet 4 is revised.

6. Clear and grub dimensions area. The plans do not give a scale for the given dimensions. Can we get an accurate assessment of the area that is intended for clearing and grubbing? Dimensions are provided to calculate area for clearing and grubbing. See revised drawing sheet 3, Demolition Plan labeling the Limits of Construction to clarify the project area.

7. In general, almost all of the dimensions shown are contradictory to what is or should be the actual measurement Use dimensions provided; see revised drawings.

8. The design of the culvert is generally based on the NMDOT standard specification. The standard spec only covers culverts up to 4 barrels. The proposed culvert is 6 barrels, is there any engineering documentation or certification that this 6 barrel culvert would not require different layout, thickness, concrete strength for the culverts and the attached wing walls and aprons? New Mexico DOT Standard Drawing 511- 59-1/2 covers the configuration of concrete box culverts (CBC) with more than 4 barrels, see specification Section 33 40 00, 2.1.3.

9. The culvert appears to be covered under the provided storm water specification. In that specification there is a reference to Section 03 30 00 Cast in Place Concrete but no such specification for this project is provided. Is it intended that these culverts are to be cast in place, if so will the intended CIP specification be provided? Yes.

10. Is precast an option? Not for bidding purposes.

11. What is the intended depth of the lowered water line? (42” to top of pipe?) See revised sheet 4, Site Plan, lowering waterline, for final cover of the proposed waterline to be 42” to the top of pipe.

12. Will the specifications for the connection materials needed for the waterline be provided? The materials for the waterline connections are as per industry standard, see attached Las Cruces Water Line Lowering.

13. Blow off valve. There does not appear to be any specifications, details or responsibility for connection of the proposed blow off valve? See revised drawings for correction: the existing blow off assembly is not a blow off valve. A Mueller gate valve is connected to the main 12” waterline with a ductile iron spool then rises up to above ground elevation with a 45-degree fitting and DI spool; once above ground there is a 90-degree bend fitting with a flap (Mueller) to direct discharge into the arroyo.

14. What is the communication line made up of (fiber optic, CAT type, Coax, etc..)? What is the minimum depth? Who is responsible for the communication line and conduit connections? Is there any conduit currently? If so, what type? The existing duct contains the following: 1 each 100 pair copper; 1 each 50 pair copper; 1 each 48 strand fiber optic cable. The contractor shall remove and replace both copper lines as necessary to accommodate the proposed vertical relocation, min. 2 ft depth.

No splicing will be acceptable. Provide concrete encasement as per the 13A Standard.

15. Will the governments Hydraulic Analysis for this drainage be provided? No

16. Existing topography and Design Elevations No question

17. Since no site survey or topography information is given and is required to be performed by the contractor, is there any relief language in the contract indemnifying the contractor of liability for project performance? For instance, without existing elevations, what certification is given that the proposed culverts will receive proper cover depth of the fill material, base and pavement? The contractor is responsible for construction of the project as per contract documents (scope of work, drawings, and specifications). At any time, the contractor has the right to notify the KO of any discrepancies with the project requirements upon new survey information. With the example given, the proper cover depth of the fill material, base and pavement required is certified because there are there are already 3 existing culverts with no problem.

18. With the considerable widening of the culverts at the roadway and the drainage ditch narrowing back to existing width approximately 300’ downstream, will the contractor be responsible for erosion control and bank scouring at this tapered point during construction and during the 1 year performance period? No;

the widening of the arroyo will actually dissipate the velocity and energy of the flows through the existing arroyo; thus, reducing its vulnerability to erosion and scouring.

19. Will there be relief/negotiation for any changes that are necessary from what is currently shown on plans and what will be mapped and checked after surveying is complete? No; there will be no changes to this project.

20. There is a call out for proposed guardrail on the plan sheets. How will the guardrail posts be installed over the proposed culverts? Install guardrails as per NMDOT Standard Drawing 606-GR31-16/20, “Drainage Structure Protection System” with W-beam guardrail attached to parapet wall of headwall when above culvert.

21. Does this proposed bypass road need to be paved? Yes, see Amendment 1, Bypass Road.

22. Is there a minimum storm water runoff volume requirement for culverts on this bypass? The contractor shall replace existing culverts with 6 new culverts.

23. Can the bypass simply divert down to the existing flowline of the ditch without utilizing culverts? No, the contractor shall construct the bypass road as per Amendment 1.

24. Does the Government have any estimated quantities for this project? The contractor can calculate quantities from dimensions given.

25. It does not appear that there is enough existing gabions to be removed and replaced to cover what is shown on the proposed plans. Do the existing gabions match what is being specified in the Technical Specifications for the proposed gabions? Correct, the existing gabions are shown on sheet 3, Demolition Plan with dimensions; subtract them from the proposed gabions shown on sheet 4, Site Plan to calculate the required amount of new gabions. Provide new gabions to meet specification Section 31 36 00, Wire Mesh Gabions.

26. Has the State of New Mexico and the New Mexico Society of Professional Land Surveyors been contacted in regards to removing and replacing the existing survey monument? This question is “N/A” since they do not have any jurisdiction in WSMR. We have our own National Geospatial-Intelligence Agency Support Branch; they have been notified of the project disturbing the survey monument and they are willing to coordinate with the contractor to reset the monument as per key note 6.

27. Based on the plans, it does not appear as though the proposed apron of the box culverts will extend far enough to encompass the existing location of the survey monument. Will there be any necessary considerations made to extend the apron to the location of the survey monument or considerations made to the construction of the apron to ensure that the monument does not move, settle or shift after construction? A 7.62’ x 5’ extension to the concrete apron is shown on the Site Plan for the survey monument, keyed note 6. See revised drawing for clarification of the monument’s concrete base.
