QUESTION RESPONSE

Can you confirm that no Minority Business

(MBE) Participation is needed?

This is a TOTAL SMALL BUSINESS SET

ASIDE procurement. Small Business

Subcontracting Plan are not required from small business concerns. Hence, there are no requirements for socio-economic goals.

Will the road that is being used for access need to be re-paved after construction is complete?

Roads that are outside the LOD will not require re-paving after construction. The asphalt path leading to the downstream stockpile/access area may require repaving after construction at the discretion of GSA dependent on observed conditions.

3 The stone size chart on the plans only goes up to Class 3 Stone but the details for the stone structures calls for imbricated boulders. Which of these shall be used for the single rock steps, double rock steps and rock & roll cascades?

See detail 1/18 “Boulder Sizing” Sheet 18 for requirements of imbricated boulders for use in single rock steps, double rock steps, and rock and roll cascades.

4 The temporary bridge at the top of the site is supposed to be a temporary wooden bridge but after visiting the site it appears that the span may be more than 40’ which would make it impossible to use a wooden bridge. Therefore, should the contractors use a temporary steel bridge for crossing the stream in this location?

The methods used for stream crossing are at the discretion of the contractor.

5 The site is supposed to be an imported fill site but the survey is not very recent and stream erosion has most likely occurred since the initial survey. How will this line item be paid if more fill is required than what is calculated from the plans?

A cut/fill estimate is to be provided by the bidder. The topo date is June 2014

6 Will onsite material be suitable for re-use in the fill areas?

See requirements for fill material sheet 18 of 27.

Is there any invasive species control needed for this contract?

Clearing and grubbing in the LOD area is described in sheet 18 of 27. No other invasive species control is required.

RFI LOG (08/25/16)

8a

What procedure will be used for truck deliveries of materials needed?

Truck Deliveries: Security will work with a

GSA designated POC of the Prime

Contractor in reference to scheduling delivery trucks for visits and/or badges.

However, Security will require the Prime

Contractor to submit that information prior their arrival. What Security recommends for deliveries, is that the contractor submit a list of individuals that might visit the campus for the next 120 days. Security will clear that list, and put them in for 120 day visit requests. Every 120 days (4 months) the Prime would need to resubmit the list of delivery drivers to be re-validated for the next 120 days. Security does not usually provide permanent IDs to delivery drivers due to the infrequent visits, as well as the high turn over rate. It is more economical to place them in for long term visits, which allows them to have visitor badges only for the duration in which they are on Campus.

8b

What procedure will be used for approval on on-site personnel?

On-Site Personnel: The Prime Contractor will appoint a POC to submit the appropriate paperwork to Campus Security for all construction and site personnel.

Security will clear and approve badge issuance. Badges may be renewed every

120 days for the duration of the project.

Is the past performance questionnaire needed for all bids or just the apparent low bidder?

(2) comparable projects substantially completed within the last five (5) years.

11 Will the contractor, in concert with GSA and the designer, be able to modify the access road location to ensure safe passage over the channel on the upper section of the restoration area?

DOEE. The location of bridge crossings within the LOD may be modified to accommodate existing conditions.

12 How will handle GSA handle the difference in material used on the project?

Contractors will calculate volumes of materials based on the plans, however, field conditions will have changed since the baseline survey data was collected and the volumes will subsequently vary.

Current cut/fill estimate is 2065 cubic yards cut and 1321 cubic yards fill. The net cut is 744 cubic yards. The condition of this material is unknown but assumed suitable for fill. Additional quantities shall be paid for at an agreed upon price to be determined following award.
