RFQ #9155 – CONSTRUCTION MATERIALS TESTING AND

GEOTECHNICAL INVESTIGATION FOR THE CITY OF DENTON

SCOPE OF WORK

1. PURPOSE

The purpose of the RFQ is to award a professional services contract for construction material testing and geotechnical services on capital projects and other construction projects. It is the intention of the City of Denton to award the contract for three (3) years, with the option to renew from the date of award for an additional two (2) one-year periods

2. SCOPE OF SERVICES

The scope of work outlined in this RFQ is preliminary, and a final scope will be negotiated with the selected firm and modified as needed. The consultant hereby agrees to perform the services as described herein, the Standard Details, and within the final agreed upon proposal in connection with this project.

The scope of work includes, but not be limited to the following:

A. Asphaltic Concrete/ Bituminous Materials Observation/Testing

• Asphaltic concrete mix designs

• Confirmation of mix design

• Observations/sampling at batch plant or jobsite

• Rolling pattern field nuclear density test

• Asphaltic concrete coring

• Laboratory density of pavement cores

B. Portland Cement Concrete and Aggregates Observation/Testing

• Portland cement concrete mix design

• Confirmation mix design test cylinders

• Confirmation mix design test beams

• Gradation (ASTM C-136)

• Sieve analysis

• Sulphate Soundness

• Concrete Coring

• Compressive strength test

SCOPE OF WORK

C. Soil Observation/Testing Continuous observation and testing of earthwork

• In-place moisture-density

• Moisture density relationship

• Moisture density relationship with lime or cement

• Strength and durability of cement stabilization

• Provide recommendation for soil stabilization

D. Geotechnical Investigations/Drilling Services

• Geotechnical Investigations and Contract Drilling Services

• Drilling Services

• Laboratory Testing

• Professional/ Technical Service

• Comprehensive report with site conditions and recommendations

E. Observation/ Testing of Structural Steel/ Welding

• Visual Inspection and Reporting of steel reinforcing bar

• High strength bolt tension testing

• Inspection of welds

3. PERFORMANCE SPECIFICATIONS

The City of Denton will provide a list of locations and or streets for geo-technical investigation and provide stabilization recommendations in the reports. The testing firm will follow the prioritized list provided by City of Denton unless a change order is requested in writing and approved.

Provide report and recommendations within 4 weeks of the request. This includes the following:

1. Utility line locates when taking core samples

2. Samples must be taken at a minimum depth of 36 inches for Street Department Projects

3. Provide a soil stabilization recommendation as part of the report

Testing firm will respond to request for material sampling within 24 hours.

Geotechnical engineering services in support of DME substation, transmission line, and distribution line projects. Services will include, but are not limited to, the following:

1. Soil Borings – Boring locations will be identified for substations, transmission structures, and distribution line facilities as required.

SCOPE OF WORK

2. Sampling depths will be determined on a project basis. Typical depths may extend to 50-

60 feet or deeper, depending on anticipated foundation pier requirements and subsurface condition.

3. Comprehensive report documentation including subsurface conditions, soil resistivity, potential vertical movement (PVM), groundwater observations, and design recommendations for earthwork, structural foundations, and other project needs.

4. Other tasks may include traffic control measures, backfill, pavement replacement, or other means to safely perform work and return the site to existing conditions.

4. CORE SUBMITTAL REQUIREMENTS

Sealed qualification submittals will be accepted either electronically in Ionwave or hard copy as outlined within the solicitation in Ionwave. The responding firms shall provide all documents necessary to support their qualifications and include them in their submittal.

Please include at a minimum the following:

• Identify the location of the office your firm proposes to provide these services from, and number of staff (by position) in that office.

• Identify the municipal clients in Texas your firm has provided material testing, special inspections and geotechnical engineering services, and years that municipality has used your firm’s services. Include at least 3 references with contact information for each reference.

B. Qualifications of the Team

• Provide the resumes of the team your firm proposes to provide services to the City, and an organizational chart showing their relationships.

• Include the Registered Professional Engineer (and their Texas Registration #) who will be overseeing the work, and at least two Engineering Technicians (or similar title) that will be observing the work in the field.

• Provide the resume of the individual(s) who will be managing the operations of testing laboratory for these services.

• Each resume should include, at a minimum, years of industry experience; years with the present firm; and key educational and other unique qualifications.

C. Quality and Information Management

• Provide a brief narrative of how this team will ensure the quality of materials testing services is provided at the highest level.

SCOPE OF WORK

• Explain how test results, reports and other deliverables are stored, managed, and distributed to the project teams your firm works with. Pay special attention to how failed test results are tracked through the correction and verification process, and any unique tracking systems used for this process.

• Provide examples of geotechnical report and construction material testing reports including boring logs, concrete, field density, etc.

D. Available Services

• An Excel spreadsheet with a list of common materials testing, special inspection and geotechnical engineering services has been provided as Attachment 1 –

Services Available.

o Within the Excel attachment, identify what services your firm does (and does not) provide, along with any comments.

o A section has been provided at the end of the attachment for your firm to add any other services you believe the City may find useful but are not outlined with the list of services provided.
