ADDENDUM NO. 5 – QUESTIONS AND ANSWERS

1. QUESTION: In the GDR and GBR, “Hardness” is reported in psi. It appears that the Hardness Number measured by the Schmidt Hammer has been correlated to estimate Unconfined Compressive Strength in psi. The basis for the correlation is not provided. Please provide the correlation curve relating Hardness Number and Unconfined Compressive Strength. ANSWER: The correlation for all the hardness testing used was the manufacturer’s chart provided by Humboldt, please see Figure 4 below, which is copied from page 5 of the Product Manual for the Humboldt H-2987 Concrete Rebound Hammer. All testing was performed with the hammer in the vertical (downward) orientation, using curve “A.” Please note that Schmidt hammer results are intended only to provide comparative hardness of materials, not a measure of compressive strength. Uniaxial testing was performed for compressive strength, and the results of said uniaxial tests are presented in the GDR and GBR.


2. QUESTION: The Geotechnical Data Report (GDR), Section 3.4, on Page 3‐8 states the following: “Rock classifications were made in accordance with the International Society for Rock Mechanics Commission on Standardization of Laboratory and Field Tests (1981). The primary components of rock classification system are shown on the boring log legend in Appendix A.” Appendix A, however, contains no legend to provide this information. Please provide the described legend information, defining terms and ranges for terms used on the boring logs including degree of fracturing (or fracture spacing), roughness, aperture, fracture fill material, and degree of weathering. ANSWER: A legend of terminology used for the rock mass and rock discontinuity descriptions is included with Addendum 2 to the GDR, which is part of this Addendum #5. (Addendum #5 p-32 to p-34)

3. QUESTION: Would the Owner please consider adding a standard aggregate and delay damages liability cap to the Contract? ANSWER: No, there is no cap on aggregate and delay damages liability.

4. QUESTION: In Addendum No. 2, Page 10, under Contractor’s Safety Record, it states “The BIDDER must provide safety records and Experience Modifier Rate (EMR) from the local OSHA office in which the firm is located.” Are Bidders required to submit any additional safety information In addition to Safety Record Affidavit Form? If so, please specify. ANSWER: The only safety information required to be submitted with the Bid is a completed Form 8 for the Prime contractor only, or for a Joint Venture, a completed Form 8 for each member of the Joint Venture.

5. QUESTION: Aside from the experience and safety sections, no specific instructions were provided in the specs on how to submit as a Joint Venture. Please clarify how a Joint Venture firm should submit the proposal forms. ANSWER: A Joint Venture is a single entity with whom the City of Dallas would enter a contract if they are the successful bidder. The Proposal Forms are to be filled out as a single package irrespective of which Joint Venture partner, subcontractor, or supplier is doing the work. Experience presented must be the experience of the Joint Venture partner that will perform the work if the Joint Venture is the successful bidder, but no further information is required with the Bid.

6. QUESTION: Tunnel Boring Machine (TBM) Mobilization is paid under Item 110Z, which is limited to the acquisition, transportation, setup, TBM spare parts, and any component that is mounted directly onto the TBM. Please clarify which Pay Item covers the disassembly and de-mobilization of the TBM Machine. ANSWER: Demobilization of the TBM shall be incidental to Item No. 147, Tunnel Type A, B, C and D – TBM Excavation and Rock Dowel Support.

7. QUESTION: Section 02950 Item 4.2.A.1 describes that payment for the TBM Excavation and the rock dowels for Tunnel Types A, B, C and D will be paid under item 147. This bid item’s quantities include the entire length of the Tunnel excavation. Section 02950 Item 4.2.A.3 describes Bid Item 149 payment that includes the TBM excavation for Tunnel Types E and F. Please clarify the duplication of excavation quantities between Bid Items 147 and 149. ANSWER: Payment for Tunnel Types E and F include excavation. There is no plan quantity for Item No. 149; this item and a quantity of 80 Linear Feet is included to establish a unit price in the event that steel rib initial support is required. Bid items will be paid on installed quantities verified in the field.


8. QUESTION: There appears to be an error in the payment section of Section 02991. Bid Items 192E through 192H are for Grout Time; however, the payment paragraphs 4.2.E through 4.2.H describe payment for mobilization. Please clarify. ANSWER: A revision to Section 02991 is included with this Addendum #5 to correct the descriptions for payment of Bid Items 192E through 192H. (Addendum No. 5 p-15 and p-16)

9. QUESTION: Will requests for product substitutions be approved during the bid process? ANSWER: Substitution requests from the Contractor will only be considered after contract award and in accordance with the contract provisions.

10. QUESTION: Where is Detail 5 shown on Sheet MD-401 located? What is the pay item for the 3” Lueder Limestone Cap shown on the top of the retaining wall? Where is the stone veneer wall located on Sheet LD-101? ANSWER: Detail 5 shown on Sheet MD-401 is for the stone veneer retaining wall shown on Sheet A4CD-306. Payment for the 3” Lueder Limestone Cap shall be at the unit price bid for Item 4009B, Stone Veneer. There is no stone veneer wall on Sheet LD-101; the stone veneer and cast stone cap are for the drop shaft; refer to Detail 3 on Sheet MD-401. (Refer to Addendum No. 3 and this Addendum No. 5 for additional information.)

11. QUESTION: Section 15060, paragraph 2.1.G requires approval by a nationally recognized testing agency such as U.L. or F.M. Can this requirement be removed for the pumps? ANSWER: No; the pumps must be approved by a nationally recognized testing agency in accordance with Section 15060, Dewatering Pumps and Accessories.

12. QUESTION: After consultation with the McCommas Landfill as suggested by the bid documents, we were informed that the tipping fee for clean soil at McCommas is $21.50 per ton, and that at this time there are no special rates for materials from this project. Will the City of Dallas consider negotiating a special rate for this project in order to reduce such costs? ANSWER: Surplus excavated material, trash, and debris emanating from the Project shall become property of the CONTRACTOR, and CONTRACTOR shall properly and legally dispose of said material offsite. There is no requirement to dispose of materials at the McCommas Bluff Landfill, and there is currently no plan to negotiate a special rate to dispose of materials at the McCommas Bluff Landfill.

13. QUESTION: Is a permit required on the total project or just the dewatering pump station? ANSWER: A building permit is required only for the Dewatering Station building, not for the entire project.

Rock Mass General Terminology

Rock Continuity Extremely Fractured – Majority of core

segments < 1 in long Moderately Fractured – Majority of core

segments 1 to 4 in long Slightly Fractured – Majority of core

segments 4 to 8 in long Sound – Majority of core segments > 8 in long

Field Hardness

Very hard – Cannot be scratched with knife Hard – Can be scratched with knife with

difficulty Medium Hard – Can readily be scratched with

knife Soft – Can be gouged with knife Very Soft – Can be grooved with fingernail

Weathering

Fresh – Rock mass and discontinuities are unstained

Slightly Weathered – Discontinuities only show some staining

Moderately Weathered – Discontinuity surfaces stained, some discoloration into rock

Highly Weathered – Rock fragments are stained, some rock is altered or decomposed

Severely Weathered – Majority has decomposed to a soil like consistency

Texture

Fine Grained – Grains barely visible up to 1/16 in

Medium Grained – 1/16 to 3/16 in Coarse Grained – 3/16 to 1/4 in Very Coarse Grained – grains > 1/4 in

Bedding/ Foliation

Laminated – less than 0.5 in Very thin – 0.5 to 2 in Thin – 2 in to 1 ft Medium – 1 to 3 ft Thick – 3 to 10 ft Massive – greater than 10 ft

Joint Spacing

Very Close – Average spacing 0.5 to 2 in Close – Average spacing 2 in to 1 ft Moderately Close – Average spacing 1 to 3 ft Wide – Average spacing 3 to 10 ft Very Wide – Average spacing >10 ft

Rock Discontinuity General Terms Type

Joint – No noticeable displacement between faces

Shear - Discontinuity has undergone displacement between faces

Fault – Major fracture(s) which have undergone large displacement

Angle Measured from the horizontal as noted as the perpendicular to the long axis of the core.

Horizontal – 0 to 5 degrees Low angle – 5 to 30 degrees Moderate angle – 30 to 60 degrees High angle – 60 to 85 degrees Vertical – 85 to 90 degrees

Weathering

Fresh – No visible weathering Discolored – Some staining of joint face Decomposed – Portions of face are

decomposed to soil Disintegrated – Rock at discontinuity has fully

weathered to soil Roughness Large Scale Appearance

Stepped – Joint exhibits small singular steps Planar – joint lies largely within a single plane

across core Undulating – Joint exhibits a curved profile

Small Scale Appearance

Rough – Joint surface is rough to the touch Smooth – Joint surface is largely smooth Slickensided – Joint surface is very smooth

and appears polished Aperture

Tight – Less than 0.02 in Open – Between 0.02 and 0.1 in Wide – Greater than 0.1 in
