Responses to Written Questions

Note: See Pre-Bid Conference Record for additional questions and answers. Some written questions received to date may not be included in this Addendum, and are being evaluated for a response. All written questions received by July 6, 2020 will be responded to by July 8, 2020.

1. Question: Will cad files be available?

Answer: We are not providing CAD files during bidding phase. Some but not necessarily all CAD files, such as the site base, will be provided to the awarded Contractor (with signed CAD release agreements as appropriate). This will be coordinated further after Contract Award.

2. Question: The NON-PARTICIPATING ITEMS on the Bid Form that involve MLGW really need to be an allowance as MLGW will not give the cost to a contractor until the contractor has an executed contract in hand with the owner. There also does not seem to be much rhyme or reason to how they figure their costs, as each connection is figured separately.

Answer: See Clarifications and Modifications to Bid Documents, ITEM 5.

3. Question: Going thru the Bid Form and making an excel version, I have come across several ITEMS that require “colored” concrete. Has the actual color to be used been selected?

Answer: This information is included in the construction drawings on various L-sheets including (but not limited to) L500, L510, L511, L512, L513, etc. Also refer to specification section 02515.

4. Question: on Sheet S001, Note G under Foundations refers to Capacity of Helical Micropiles

50 kips compression, 15 Kip Tension

We need to know if these loads are working loads or ultimate loads?

Example: Live load + Dead Load = Working Load

Working Load x Safety Factor of 2 = Ultimate Load

We install to Ultimate Loads. So basically we need to know if are we installing to 50 kips or 100 kips. This is important because it is 2 different materials.

Answer: The loads shown are working loads.


5. Question: Regarding the “prequalification questionnaire packet to TDOT at least 14 days prior to bid opening”. Are the referenced 14 days, working days or calendar days?

Answer: It is 14 business days, but it could take longer due to TDOT personnel working remotely, and this timeframe does not include any changes that may have to be made.

6. Question: Bid Item #31 on sheet G001, states “See Keynote C on sheets L102 & L103” concerning 240 SF of concrete pavers @ crosswalks. No keynote C is given. No work appears on either the demolition drawings or hardscape site layout drawings regarding concrete pavers @ existing crosswalks. Please clarify.

Answer: See Clarifications and Modifications to Bid Documents, ITEM 7.

I. PRE-BID CONFERENCE

A. Welcome & Opening Remarks

Jim Reeder (JR) with Memphis River Parks Partnership welcomed all attendees to the non-

mandatory Pre-Bid Conference and thanked them for their interest in the project. He asked

attendees to legibly fill out the sign-in sheet with their name, firm name, telephone number and

email address. Contractors/subcontractors were advised that they needed to sign in, so they could

receive an official copy of the Pre-bid Conference Record. The sign-in sheets are attached.

JR reviewed the recommended procedures related to COVID-19 and asked that everyone maintain

6-foot social distancing during the meeting and site visit. Lee Wilson (LW) also advised that face

masks and alcohol hand sanitizer was available to the attendees, as well as bottled water.

B. Introduction of Project Team

JR introduced the project team present:

City of Memphis - Mike Lemm, Project Manager


Tetra Tech - Lee Wilson, Senior Civil Engineer

Ritchie Smith Associates - Ritchie Smith and Looja Shakya, Landscape Architects.

JR advised that Pan American Consultants (not present) will be performing archaeological and

historical preservation activities during construction, under contract with Tetra Tech. JR advised

that the Tennessee Department of Transportation (TDOT), not present, would provide a significant

role in the project.

C. Project Overview

The main purpose of the project is to restore the existing Cobblestone Landing due to its current

degraded condition.

JR advised that the project was funded in large part from Federal Highway Administration funds,

administered by the TDOT, in a grant agreement with the City of Memphis. JR advised that the

project Bid Documents were based on TDOT standards, and this is not a typical City of Memphis

solicitation. JR advised all attendees to carefully review all of the Bid Documents.

The Construction Contract Duration is 730 calendar days (2 years) from the date of the Notice to

Proceed.

D. Meeting Guidelines

JR advised that any statements made by project team members at the meeting were meant to be

advisory for contractors interested in bidding on the project and/or subcontractors who may be

working with the prime contractors. However, if any statements made by project team members

appear to be in conflict with the Bid Documents (Proposal contract, construction drawings,

specifications, etc.); or if any attendee believed they heard project team members making any

comment in conflict with the Bid Documents, then the Bid Documents shall govern and those

statements shall be disregarded.

JR informed attendees that if they had questions on the Bid Documents or needed clarification, to

submit those questions/clarifications in writing to Tetra Tech. Official responses will be provided in

writing. JR advised that Lee Wilson would also discuss this process later in the meeting.

E. Project Description and Scope of Work

LW described the project scope which involves restoration of the historic Memphis Cobblestone

Landing and related site improvements. The project site is located between Wolf River Harbor and

Riverside Drive, north of Beale Street Landing and south of Mississippi River Park. The scope of

work includes, but is not limited to the following:

1. Bank stabilization with placement of open-cell and closed-cell articulating concrete block

(ACB) revetment mat systems, and limited riprap placement;

2. Removal of silt, vegetation, concrete and asphalt from the cobblestone field;

3. Filling of eroded and depressed areas of the cobblestones;


4. Installation of salvaged historic cobblestones and new tumbled concrete cobbles;

5. Repairing and restoring the historic mooring rings and the river gage;

6. Construction of an accessible walkway connecting to the cobblestone field between the

Monroe Avenue overlook area and the Court Avenue entrance;

7. Installation of two pedestrian overlooks with stairs and interpretive plaques at Union

Avenue and Monroe Avenue overlooks;

8. Installation of a decorative fountain and pedestrian lighting at the Union Avenue overlook;

9. Installation of two 10-foot color concrete bands which run east/west along the southern and

northern edge of the historic cobblestone field; and two 8-foot concrete utility corridors

which are oriented east/west at the Union and Monroe Avenue overlooks;

10. Removal of above-ground utilities in the cobblestone field area;

11. Installation of underground electrical and potable water facilities, from the MLGW points of

connection to the utility corridor located west of the Union Avenue overlook;

12. Installation of a utility room beneath the Union overlook for electrical and plumbing

equipment and piping;

13. Installation of bored piles (helical pulldown micropiles) to support the Union Avenue

overlook structure; and

14. Limited landscape plantings.

F. Historical Background

Ritchie Smith (RS) discussed the historical significance of the project. The Cobblestone Landing, also

referred to as the Memphis Landing, dates to the founding of Memphis in 1819. At that time, the

Riverfront Promenade was established as a continuous band of public land along the riverfront to

accommodate a future river landing and public buildings along the bluff top. The Promenade was a

bold civic gesture and extended from the river shoreline east up the bluff and to Front Street. The

street grid pattern for Memphis also included four public squares, the most prominent being Court

Square.

The Memphis Landing was established in 1838 and is a nationally significant inland river port. At

over 7 acres, it is the largest remaining cobblestone landing in the U.S. It is a national historic

landmark; and in 2011, was listed in the National Register of Historic Places. The Cobblestone

Landing is also part of the Cotton Row Historic District, listed in the National Register in 1978.

Memphis Landing was generally unpaved until 1859 when cobblestones were laid on a 7:1 gradient

to stabilize the slope and accommodate rapidly growing riverboat traffic. The cobblestones were

installed in three periods: 1859-1861; 1866-1868; and 1880-1881. When completed the

cobblestones extended from Court Street south to Beale Street, and from the harbor’s edge east to

the railroad tracks. In the 1930s, Riverside Drive was built over the east edge of the cobblestones.

The Memphis Landing includes approximately 90 cast iron mooring rings used by riverboats in the


past, and an historic iron gauge near the south end. The cobblestones themselves include granite

and other rock types, mostly of igneous origin, from the Upper Midwest. Riverboats carried these

stones downriver as ballast. The stones were laid on compacted earth with sand joints.

Due to the historic significance of the Memphis Landing, and in compliance with Section 106 of the

National Historic Preservation Act of 1966, the contractor must exercise extreme care during

construction of the project. In the construction drawing set, the X-sheet drawings include detailed

procedures for restoring various areas of the cobblestone field, while preserving other areas

including the cobblestones, mooring rings, and river gauge. Most of the cobblestone field is in good

condition with little work required, but other areas have settled or missing cobblestones, or those

overlaid with sediment, gravel, asphalt or concrete. The Contractor will be responsible for repairing,

at their expense, any alteration or damage to historic features which are designated to be

preserved.

G. Permits and Special Project Requirements

JR discussed permitting and special project requirements related to construction of the project.

1. Environmental Permitting / Restrictions

The project site is subject to flooding from the Mississippi River and the Wolf River Harbor.

The contractor would be able to perform work when river stages are favorable. Refer to

Specification Section 01315 - River Stages in Volume I - Proposal Contract; and to the

Historical River Stages Section in Volume II - Appendices for more detailed information

regarding river stages. The current construction contract duration is 730 calendar days, and

if favorable river stages do not occur during this contract period, the contractor may be

eligible for a time extension.

The Contractor will be prohibited from undertaking any construction activities that involve in-stream work during the period of April 1st through June 30th of any calendar year during the construction contract duration. This requirement is for the protection of the spawning period of the Pallid Sturgeon and the Blue Sucker.

The project required a Tennessee Department of Environment and Conservation (TDEC) Water Quality Division ARAP Permit/Section 401 Water Quality Certification, and U.S. Army Corps of Engineers’ Section 404/10 Permit and Section 408 Permit The project construction activities shall follow any stipulation and/or provisions contained in these permits. The bidders should carefully review these permits to ensure their construction activities will comply.

Prior to construction, the contractor will be required to execute the project’s Notice of Intent (NOI) and Contractor Certifications for General NPDES Permit for Stormwater Discharges from Construction Activities.

Copies of the above-referenced permits were included in the Proposal Contract with SP107FP (Special Provision Regarding Water Quality and Storm Water Permits).

2. Railroad Coordination


The project design includes electrical work within the right-of-way of Canadian

National Illinois Central (CNIC) Railroad, and the Contractor shall coordinate

fully with the CNIC Railroad for this work. Refer to Special Provision SP105C in

the Proposal Contract for specific railroad coordination requirements. LW

stated there were also notes on the construction drawing (E162) related to this

railroad coordination.

3. Local Agency Permitting

The project’s construction drawings have been reviewed by the

Memphis/Shelby County Construction Code Enforcement Office. The

Contractor will have to pull the Building, Electrical, and Plumbing permits

required for the project. (Note: At the meeting the project team stated that

the drawings were approved by Code Enforcement. While this is mostly

accurate, there are some additional documents such as shop drawings that

need to be submitted by Contractor before the permit can be obtained. This

will be further clarified by Addendum.)

The contractor must obtain a City of Memphis Street Cut Permit for the project.

LW stated that this is required for construction in the Riverside Drive Right-of-

Way and public drainage infrastructure near the north end of the project. A

separate set of 24”x36” drawings were reviewed and approved by City of

Memphis Engineering Department; but the awarded Contractor will have to

pull the permit from City Engineering. The construction information on the

24”x36” drawings is also shown on the 30”x42” drawings issued for bid

(although the plan scales are different for some sheets).

J. Miscellaneous

JR reviewed the City of Memphis requirement for additional contractor’s liability

insurance requirements which exceed TDOT’s requirements. The City’s additional

insurance requirements are specified in the Proposal Contract’s Supplemental

Conditions, Part I – Additional Contractor’s Liability Insurance. The Contractor shall not

commence work until it has obtained and provided to the City of Memphis proof of all

of the additional insurance requirements.

LW stated that the prime General Contractor is required to self-perform at least 30% of

the work, per TDOT requirements.

LW stated that there is a City of Memphis standard specification in the Proposal

Contract bid book, regarding which Inclement weather delays. Specification Section

01310 establishes a baseline in days, which if exceeded can be considered for time

extensions due to weather; but not due to river stages.

LW stated that working hour limitations are 6 AM to 6 PM unless otherwise directed by

the City. The construction site is expected to be accessible at all times, but during

special events such as Memphis in May there could be some traffic congestion in the

area.

LW described the MLG&W utility connections which are proposed for the project,

including potable water and electrical services. There is an existing 400-amp

electrical service to the riverboat facilities at the landing, which will be modified from

an overhead to underground system. A new 125-amp service for the new fountain and


utility room lights/outlets will also be installed (note: this may have been mistakenly

stated as 110-amp service at the meeting. Please disregard). Pay items for the work

to be performed by MLG&W for these connections are included in the bid form. An

Addendum will be issued regarding the amounts to be used by all bidders on these

items.

K. Adjournment

The pre-bid conference at Fourth Bluff Park was adjourned at approximately 11 AM

CST; and attendees were directed to the non-mandatory site visit immediately

following at Cobblestone Landing. A separate sign-in sheet or attendee list for the site

visit was not prepared by the project team.

II. SITE VISIT

The site visit began at the north end of the Cobblestone Landing at Riverside Drive and

Court Avenue, immediately south of the River Garden at Mississippi River Park. RS led the

group on a site walk south to Union Avenue and described a number of key features in the

project scope.

Pedestrian enhancements at the north end include new steps going down to the

cobblestones at Court Avenue, connecting to a concrete edge band that will stabilize and

contain the north edge of cobblestone field. The same edge band will occur on the south

end of the cobblestones. These edge bands and all concrete paving within the cobblestone

field will be a special concrete mix with gray color admixture and sandblasted finish.

Another feature in this area will be an approximately 600-foot long accessible walkway

along the east edge of the cobblestones, extending from the north ramp at the Monroe

Overlook area to the Court Avenue Entrance.

RS described the improvements at Monroe Overlook including removal of all asphalt paving

and replacement with historic stone cobbles salvaged from this project. The metal

guardrail along the west edge of the two vehicular ramps will be enhanced with steel pipe

rail. An interpretive area with a mooring ring exhibit and plaque will be in this area at the

top of steps. At the Monroe Overlook area, RS led the group for a walk on the

cobblestones to review various restoration conditions in the scope of work. RS noted that

historic stone cobbles salvaged from this project will be used for infill and restoration

within the historic field. Beyond the historic field to the west, tumbled concrete cobbles

will be used if the supply of stone cobbles is depleted.

The site walk concluded at the location of the proposed Union Avenue Overlook. RS

described the plaza that will extend west beyond the current retaining wall. LW noted that

the top portion of this retaining wall will be removed to accommodate the plaza. Grand

stairs will descend to the cobblestones from the north and south ends of the plaza. The

focal point of the plaza is a fountain, with fountain elements and perimeter seat walls

constructed of granite. The plaza will include Cotton Row post lights and interpretive

plaques along the west railing. Below the plaza is a utility room containing piping, conduits


and equipment related to the electrical and plumbing services. Most of the fountain

equipment will be in a prefabricated vault which will be at the Riverside Drive west

sidewalk, south of the overlook plaza.

West of the Union Avenue Overlook, and also west of the Monroe Overlook, color concrete

paving bands will extend to the west edge of the cobblestone field. Beneath the paving

band at Union area will be a corridor for the new underground utilities. LW noted that all

overhead utilities, power poles, wires etc. in the cobblestone field will be removed as part

of the project.

JR discussed the open- and closed-celled articulating concrete block (ACB) revetment

system that will be installed along on the west edge of the project. This will provide

protection against erosion and bank scouring. Over the decades, bank erosion and scouring

resulted in cobblestones being displaced and lost in the harbor. JR and RS noted that the

ACB material is similar to that used at Beale Street Landing, immediately south of the

Cobblestone Landing.

JR noted that the ACB revetment will have a gentler slope on the northern end of the

project to provide a landing and launch area for small boats such as canoes and kayaks.

JR pointed out the existing electrical cabinet on west side of Riverside Drive, which will

serve as the power source for the permanent electrical services.

JR also noted that the Contractor will have to provide safe access for the employees of the

Memphis Riverboats across the construction site, to their floating dock facility (string out)

which is located along the Cobblestone Landing water’s edge in the Wolf River Harbor. JR

also stated that the Memphis Riverboats would be required to move their facility north and

or south along the Harbor to accommodate construction.

The site visit was adjourned at approximately 12 PM CST (noon).

III. QUESTIONS AND ANSWERS

This section includes oral questions asked during the Pre-Bid Conference and Site Visit on July 17, 2020.

Any oral statements at the July 17 event in response to said questions are non-binding; but the answers

below are to be considered official responses.

Other questions received in writing will be responded to by Addendum to all official Plan Holders.

1. Question: Will the Memphis Riverboats string out be removed during

construction?

Answer: The Memphis Riverboats string out (floating dock facility) will remain in

the Wolf River Harbor adjacent to the Cobblestone Landing; but will be required to

move north or south along the harbor as required to accommodate construction. It

should be noted that the Memphis Riverboats boards and deboards passengers on

their vessels from the Beale Street Landing facility and not at the Cobblestone


Landing. The contractor will also be required to provide daily access for Memphis

Riverboats employees from Riverside Drive to the floating dock facility. See

paragraph 1.3 of Section 01140 - Work Restrictions for more information.

2. Question: Do subcontractors have to be prequalified with TDOT?

Answer: Yes, a prospective subcontractor must be prequalified by TDOT and in good standing with TDOT prior to being approved as a subcontractor during the contract award phase. However, unlike prime contractors, subcontractors do not have to be prequalified by the date of Bid Opening. For additional information, refer to the paragraphs "Prequalification of Bidders” and "Licensing Requirements" in the Instructions to Bidders section of the Proposal Contract.

3. Question: How will the contractor be paid for the removal of debris, tree limbs and sediment from the project site?

Answer: The Contractor will be paid a lump sum for clearing and grubbing (Pay Item No. 201-01). This will include all debris and sediment removal on the project site at the time construction commences. Any additional removal of disposal of trash and debris will be paid for by the cubic yard per Pay Item No. 202-01.04, and the removal of sediment will be paid for by the cubic yard per Pay item No. 209-05. Refer to the pay item footnotes on drawings for additional information.

4. Question: What was the gauge reading at the Memphis Gauge on Wednesday June 17, 2020,

the day of the pre-bid conference?

Answer: The gauge reading as recorded at 6:00 AM on 6/17/2020 at the Memphis Gauge was

17.6 feet.

5. Question: Can the gauge readings at the Memphis Gauge be used to approximate the water

surface elevations at the Cobblestones?

Answer: Yes, the Memphis Gauge readings can be used to approximate the water surface

elevations at the Cobblestone Landing. Zero reading at the Memphis Gauge is 183.9 feet

NGVD. All else being equal, there is approximately a 1.1-foot rise in river water surface

elevation from the location of the Memphis Gauge further south, to the location of the

Cobblestone Landing at Wolf River Harbor. Therefore add 1.1 foot to the water surface

elevation at the Memphis Gauge to determine an approximate water surface elevation at the

Cobblestone Landing. For example, if you have a Memphis Gauge reading of 5 feet, the

approximate water surface elevation at Cobblestone Landing would be 183.9 + 5 + 1.1 = 190.0

Feet, NGVD. This computation is further described in the SECTION 01315 – RIVER STAGES.

6. Question: Will the cobblestones at the Monroe Avenue ramps need to be grouted?

Answer: In accordance with Site Layout Plan 1/L403 in the construction drawings, cobblestones


will have grout joints only at and near the top of Monroe Landing, at and near the elevation of

Riverside Drive. Refer to the hatch pattern on 1/L403. Refer also to Sheet X103 and Detail

2/X500.
