1.2. WORK ELEMENTS

1.2.A. The work shall include all planning, design work, coordination, permitting, labor, material, tools, equipment, construction, testing, inspection, commissioning, and all necessary general conditions, that may be reasonably inferred from the Contract Documents to provide for all work for the design and construction of a new turnkey metal building to accommodate a new emergency generator. The new metal building and generator will be installed adjacent to the existing Retamal Dam Substation, where the damaged generator is currently located. Retamal Dam is in Hidalgo County, Texas.

1.2.B. The work shall be broken out into 2 phases.

1. Phase 1 is the Design Phase.

The Design Phase includes, but is not limited to:

a. Site investigation

b. Site surveying

c. Any required geotechnical investigations, modeling, or testing.

d. Design

e. Production of construction documents (minimum of drawings and technical specifications)

f. Production of all project reports

g. Coordination with stakeholders

2. Phase 2 is the Construction Phase.

The Construction Phase includes, but is not limited to:

a. Site preparation

b. Construction

c. Disposal of debris and construction waste

d. Quality control testing

e. Commissioning

1.2.C. Each phase shall have a separate Notice to Proceed (NTP).

1.2.D. The final product shall be a 100% completed construction project (turnkey) in accordance with the Design-Build Contract, this Scope of Work, and the construction drawings and specifications.

1.3. SEQUENCE OF WORK/TIME FOR COMPLETION OF WORK

1.3.A. After receipt of the Notice to Proceed (NTP) the Design-Builder shall comply with all submittal requirements as covered under this Scope of Work.

1. No construction shall be started, until the Government compliance confirms the required premobilization submittals. Once the Government determines that construction may proceed, will mobilization be allowed.

2. The Government will not grant any time extension for any resubmittal required when, in the opinion of the CO, the initial submission failed to meet the minimum quality requirements as set forth in the Contract.

3. If the Government allows the Design-Builder to proceed with limited construction based on pending minor revisions to the reviewed submittals, no payment will be made for any in-place construction related to the pending revisions until they are completed, resubmitted and are satisfactory to the Government.

4. No payment will be made for any in-place construction until all submittals required for that portion of the work and/or required prior to the start of construction have been made, reviewed, and are satisfactory to the Government.

00.24.00.01-Page 4 USIBWC Solicitation 191BWC26Rxxxx

1.3.B. Unless otherwise agreed to with the COR, mobilization and sitework shall begin within 90 days of the issuance of the Construction Notice to Proceed (NTP).

1. Design-Builder and Construction Contractor shall expeditiously plan and prepare their premobilization submittals and any resubmittals as well as take into account the Government's review time to meet this requirement.

2. Surveying, photographing/videotaping site, and vibration condition survey do not constitute sitework for this requirement.

1.3.C. The work under this Contract shall be completed within the timeframe specified in the Contract Provisions. Time will only stop being counted once substantial completion is achieved (Section 01.78.36.01).

1.3.D. Where FAR 52.211-10 provides specific timeframes for completion of the design, construction, and revegetation, the following shall apply:

1. Design shall be completed within the timeframe noted in FAR 52.211-10.

2. If the design is completed prior to the timeframe noted in FAR 52.211-10, the remaining days shall be applied to the construction phase. For example, if the design is completed 20 days early, 20 days shall be added to the construction timeframe.

3. If the design is completed after the specified timeframe noted in FAR 52.211-10, then the Design-Builder is behind schedule and subject to any liquidated damages or other repercussions determined by the CO. The additional time required for completion of the design shall be subtracted from the allowed construction timeframe. For example, if the design is completed 20 days late, 20 days shall be subtracted from the construction timeframe.

4. Regardless of the design completion time and the construction completion time, the timeframe noted in FAR 52.211-10 for revegetation shall begin after substantial completion has been reached.

1.4. WORK UNDER OTHER CONTRACTS

Environmental Information February 24, 2026 00.31.24.01-Page 2 USIBWC Solicitation 191BWC26Rxxxx

1.5.B. These documents lists environmentally and culturally sensitive areas that need to be protected from any disturbances of construction activities. The environmentally and culturally sensitive areas that were identified on the document are identified below.

1. Environmentally Sensitive Areas

a. USIBWC will be responsible for compliance with National Environmental Policy Act (NEPA).

USIBWC may prepare NEPA documentation concurrent with this contract and/or solicitation. The Contractor must incorporate any environmental protection measures identified in the NEPA document

2. Culturally Sensitive Areas

a. Although this area has not been previously surveyed nor cleared archeologically, USIBWC has determined that the construction of a new building on this location would not result in adverse effects on cultural properties as no historic properties will be affected.

3. Biological Resources Work should be scheduled to occur outside of the bird breeding season whenever possible.

Migratory birds may be present within the project area; birds, nests, and eggs are to be protected and avoided during construction. The breeding and nesting season is identified in Section 01.57.19.01. If work continues into the bird breeding/nesting season the areas proposed for disturbance shall be surveyed in order to avoid the inadvertent destruction of nests and eggs.

4. Natural Resources Equipment cannot be parked, staged, or used under large, mature trees. Keeping equipment away from the large, mature trees will prevent incidental damage to the tree and prevent compression of the root ball.

5. Water Quality

a. The Contractor must ensure that construction will not adversely impact on the water quality of the Rio Grande during construction (per 01.57.19.01 Part 1.9.).

6. Fuel Tanks

a. Fuel storage tanks must comply with Texas Administrative Code (TAC) 30 TAC Chapter 334 Subchapter F for aboveground storage tanks, including secondary containment.

1.5.C. Further details of environmental requirements are in Sections 01.57.00.01 and 01.57.19.01.

1.6. PRESERVATION OF CULTURAL AND NATURAL RESOURCES AND THE ENVIRONMENT

1.6.A. If the Design-Builder initiates changes to the Contract and USIBWC approves the changes, the Design-Builder is responsible for obtaining clearances and coordinating with the appropriate regulatory agencies.

1.6.B. Culturally Sensitive Areas If a site, building, or location of historical, archaeological, educational, or scientific interest is discovered within the right of way, cease all work immediately, secure the site from further disturbance and possible vandalism, and notify USIBWC. The site, building, or location will be investigated and evaluated by

USIBWC.

1.7. OTHER CONSIDERATIONS

The Design-Builder is required to ensure that all Environmental Permits, Issues, and Comments (EPIC), which are included within the Contract Documents are followed and implemented to ensure potential impacts are avoided.

1.8. USE OF GEOLOGIC MATERIALS ON A FEDERALLY FUNDED PROJECT

1.8.A. To ensure preservation of historical and archaeological data, prior to use of any soil, rock, or gravel including aggregate in concrete, the source must first be compliance confirmed by the COR to ensure compliance with Section 106 of the National Historic Preservation Act (NHPA).

1.8.B. Take no action to use or alter the proposed location until written approval for site use is received from the

COR.

1.8.C. If the quarry or borrow site already provides materials for TxDOT, USACE, or other governmental agency, a copy of the environmental approvals from said agencies may be provided to the COR.

1.8.D. Include permission for Government access to any geological source locations.
