Questions Answers

1 What is the intended plan for the excess ROADWAY

EXCAVATION Material?

Will FHWA supply a dump site within the project limits for this material?

Is the intent to use for the excess material to be utilized as

EMBANKMENT?

If the proposed use for the excess material to be used as

Embankment, will an Embankment bid item be added to the Bid Schedule?

Excess material on the project is noted as Waste (Item 20441-0000) on the grading summary (Sheet B3), and will be paid for accordingly. The Waste material will be disposed of legally outside the boundaries of the Forest. No areas within the project limits have been designated for waste.

2 Will the contractor be allowed to pump water from Bonito Creek for construction water?

The City of Alamogordo owns the reservoir downstream of the project site.

The contractor will be responsible for determining any water rights issues/payments associated with pumping water from Bonito Creek.

3 On the bid form item no. A0360 placed rip rap method a class 3:

Does the quantity listed on this line item include all of the rip rap on the project including all the rip rap shown on the box Culverts?

The drainage summary on Sheet B3 quantifies the riprap at individual sites and the total quantity includes riprap placed at box culvert and pipe culvert locations.

4 On sheet number B3 it states underneath the Grading Summary that “ roadway excavation includes excavation of bedrock at STA.

110+58 box culvert.” Is there any quantity of estimated bedrock excavation that will need to be accomplished at this location?

We estimate the rock excavation to be approximately 40 CUYD at the

STA. 110+58 box culvert.

5 Sheet Numbers D1, D2,D3 all show Class 3 Rip Rap and Granular

Rock Backdrain material going completely through all of the box culverts. Is this correct?

Yes, this is correct. The culverts are intended to serve as Aquatic

Organism Passage and the material within the culvert is intended to mimic upstream and downstream of the structures. As noted on sheets D1, D2, and D3, the granular rock backdrain is not a separate pay item and is considered subsidiary to the box culvert item.

1 Section 153.02 requires that a full-time,QCM be onsite. Section

153.02 also describes the education and work experience requirements for the onsite QCM. Can you waive the education requirements and can we substitute it with more work experience?

Can the jobsite Superintendent also be the QCM?

The requirements of Section 153.02 will not be modified. As stated in

Section 153.02, the QCM will have no responsibilities for performing testing and inspection, managing the project, or performing other operations other than managing quality control. Therefore, the

Superintendent cannot also serve as the QCM.

2 Section 154.04b requires that the contractor furnish an onsite laboratory equipped with all the testing equipment necessary to satisfy the requirements of the contract. Can you waive this requirement and can we use a commercial testing lab outside the project? The project site is in a very remote area and doesn’t have the existing utilities to run an onsite lab.

Section 154.04b states that a commercial laboratory meeting or exceeding the requirements described in Section 154 can be used.

1 Does the design expect any type of imported fill or does all of the excavation equal out as far as cut and fill across the complete project?

Based on the grading summary on Sheet B3 of the plans, the roadway excavation will generate a sufficient quantity of embankment material for this project, based on various assumptions. Approximately 358 CUYD of excavated material will be wasted outside the project limits and boundaries of the National Forest. Therefore, the design plans don’t require imported fill for embankment construction.

2 Can the QCM be allowed to operate equipment if necessary? Per Section 153 of the FP-14, “Provide a QCM with no responsibilities for performing testing and inspection, managing the project, or performing operations other than managing quality control.” Therefore, the QCM will not be allowed to operate equipment.

3 Is the QCM required to be at the jobsite each day? Can an alternate/assistant QCM be used at the jobsite full-time and the

QCM be part-time?

A QCM is required to be onsite. The proposed arrangement can be used provided that both individuals meet the requirements of Section 153 for

QCMs. The Quality Control Plan will have to address this scenario and specific roles and responsibilities.

4 Regarding the tie-ins for the cast-in-place wingwalls, do you know if having one foot of exposed box cage is acceptable? For

TXDOT projects, what we do is leave a foot of the box uncast, exposing the cage so the contractor can tie in rebar and cast in place the wingwalls, headwall, and toewalls. Please see attachments

Having one foot of exposed box cage is acceptable provided the entire system accommodates proposed wingwalls, headwalls, and toewalls.
