11/20/2024 Updated: 11/22/2024 City of Belgrade Public Works City of Belgrade – Cameron Ave Improvements – Question and Answer (Q&A) Document The following are the questions the City of Belgrade Public Works Department has received regarding the SS4A Safety Action Plan RFP. Responses to these questions are in bold following each question. 1) Regarding the 18” storm pipe on this project, item no. 111 on schedule of bid items, what types of pipes will be allowed? RCP, PVC, HDPE or PP? The In accordance with COB Design Standards and COB Modifications to RCP and PVC pipe may be used. Recently, we have approved the use of PP pipe that meets ASTM F2881. The City may approve other pipe materials on a case-by-case basis. 2) Is there an Engineer’s Estimate we can use for bid bond purposes? The City will not be sharing the engineer’s estimate until bid opening since we use it as a comparison tool. 3) Are the design files available for this project? If so, can they be e-mailed over? The City will provide the design files used during development of this project on its Bid Webpage along with the amended plan set. Reasonable efforts have been made to ensure the completeness and accuracy of this data. However, the Contractor is responsible for field verification. Use of differing software, equipment, or settings may affect this data. The City of Belgrade does not accept responsibility for these alterations. 4) Current plans do not show any existing contours and/or existing features (i.e. existing asphalt edge, flatwork, approaches etc.). Can we get this information if the design files do not contain this information? An amended plan set will be issued after the pre-bid conference. These feature lines will be turned on and included in the amended plan set. 5) Are the removals, asphalt saw cutting and excavation incidental? Or will bid items be added to cover this work? All the removals, asphalt saw cutting, and excavation are incidental to other bid items and should be included in the unit prices bid for the associated bid items for the work. All sidewalk removal should be included in the unit bid price for Concrete Sidewalks. All asphalt saw cutting should be included in the unit bid price for Combined Concrete Curb and Gutter. Excavation associated with the Underground CMP Storage bid items should be included in those bid items. Excavation associated with the 18-IN Storm ---PAGE BREAK--- City of Belgrade – Cameron Ave Improvements – Question and Answer (Q&A) Document Pipe bid item should be included in that bid item. 6) Can the bid date be pushed until after Thanksgiving week? Due to funding availability, the City is not able to move the bid date. 7) How will landscaping and irrigation system work be paid? What will be required to be sod versus seed? Per the Project Manual (Division 2, Section 02930 and 02940), landscaping is to be paid as lump sum. After all curb and gutter and sidewalk work is completed, the Contractor is to replace all landscaping, vegetation, lawn, etc. to preconstruction condition. For example, if the preconstruction condition is lawn, the Contractor will be expected to replace with sod. Per the Project Manual (Division 2, Section 02940), irrigation repair shall be paid as the Contractor’s Fee in accordance with paragraph 11.07.C of the Standard General Conditions (C-700) of the Construction Contract. 8) Will the Contractor be allowed to substitute all types of underground storage systems? No, the City of Belgrade wants to use a CMP system specifically in order to compare these systems with other underground stormwater storage systems. 9) When is the Notice to Proceed? Is there any flexibility with the set date? The Notice to Proceed (NTP) is revised to May 26, 2025. Please see Addendum 1. This is not a flexible NTP. However, the Contractor may request an adverse weather shutdown as allowed in the Project Manual. 10) Is the Contractor expected to complete the final curb and gutter and sidewalk design as it pertains to setting final grades? The Contractor is required to set final grades of curb and gutter and sidewalk in coordination with the Engineer. In general, curb and gutter and sidewalk elevations should be set to be “straight-graded” to the extent possible in order to provide appropriate drainage along the roadway to adjacent roads and to storm drain structures. The Contractor will be required to match all existing curb and gutter, pavement, approach, and sidewalk elevations at tie-in points. 11) What type of traffic control measures will be allowed? Will the Contractor be allowed to close the road? Division 1, Section 01570 has been revised to include additional traffic control requirements. Please see Addendum 1. Alternative traffic controls may be considered, but all traffic control plans shall be approved by the Engineer prior to implementation. 12) When will be the last day for pre-bid questions? The last day for pre-bid questions will be November 22nd at 5pm. An updated Q&A document will be issued as necessary. As a reminder, the bid opening will be at 3pm on November 26th. 13) Regarding Section 00200, Article 3, what information should be provided by the contractor? Please see the provided template for the required information. Please also note that per the Belgrade City Code 2-1-1, all businesses (including Contractors) operating or conducting within the City of Belgrade shall obtain a business license from the City of Belgrade. 14) Can the bid due date be postponed to a later date? ---PAGE BREAK--- City of Belgrade – Cameron Ave Improvements – Question and Answer (Q&A) Document Due to project funding requirements, the bid due date will remain at 3:00 p.m. on Tuesday, November 26, 2024. 15) Will the street name signs (D-3 signs) be 9” (as called out in the Project Manual or 10” tall (as called out in the Plans)? The signs will be 9” tall. An amended plan set will be issued to add this modification. 16) The standard spec for City of Belgrade has 3” gravel under sidewalk, but the Cameron Ave. typical shows 6” under sidewalk. Can you clarify which one controls, since it’s paid for incidental to sidewalk. The COB spec also shows 4” base under the driveway concrete. It seems inconsistent to add 6” under sidewalk and 4” under concrete driveway. For this project, we will utilize 6” of base under all sidewalks and driveways. The only exception to this is over the CMP storage structure – this section needs to have 8” of base to fulfill cover requirements. 17) No elevations for the Underground CMP Storage Units are provided, for the bottom of the CMP and where the separator piping connects to it. Can you provide elevations or depths that we will be excavating for these structures? We typically use ¾” screened rock on these projects. Is that acceptable backfill material for this CMP structure? The excavation depths will be based on pipe diameter, the backfill depth under each pipe currently proposed), and the required pipe cover (which is typically 12” min). The final design will be verified with the Contractor’s selected manufacturer and approved by the Engineer. The backfill should meet the manufacturer’s specifications – the main consideration for most storage systems is that the backfill has a minimum void ratio of 40% (this void ratio is typical for crushed/screened rock, but the Contractor must verify). 18) No design grades are contained within the provided CAD files, and they only contain the existing TIN surface. There also doesn’t appear to be any design and/or existing contours on the updated plan set. Can additional information be provided? Due to relatively flat character of the project and the observed tie-in elevations, the CIty elected to not develop the design contours. Since we are matching existing pavement elevations, earthwork quantities are expected to be minimal. 19) Can the City confirm that all inlets are to be 48” manholes; they are drawn as 96” manholes. Yes, the inlet manholes will be 48” manholes. 20) How does the gravel base underneath and behind the curb get paid? It appears you only have enough gravel quantity to cover the asphalt patching area(s). The gravel under the cub is incidental to curb, and the gravel under sidewalk is incidental to sidewalk. 21) It appears that there is going to be a gas line conflict with storm inlet I-1 @ Hoffaman/ Cameron and a fiber line conflict with the storm system @ Cameron/Broadway. Are those utilities scheduled to be relocated? From reading section 1010 1.06A it appears that maybe it hasn’t been scheduled and will be the responsibility of the contractor to schedule / coordinate / pay for this, but the owner will re-imburse the contractor for relocation costs? Typically, the owner would handle all utility relocates. ---PAGE BREAK--- City of Belgrade – Cameron Ave Improvements – Question and Answer (Q&A) Document For these two likely conflicts, the City will coordinate with the utility companies to schedule a higher-level locate and have the utilities moved if needed before the NTP. During construction, the Contractor will still be responsible for calling in all utility locates and coordinating with the utility companies as explained in the Project Manual.
