The Contractor should have qualifications and knowledge in all facets of the Project.

3.2.

BID EVALUATION. Cost to the Corporation is a material factor, but not the sole or necessarily the determining factor in proposal evaluation. The Corporation may, in its sole discretion, award a contract resulting from this RFP to a person or entity other than the responsible and qualified bidder submitting the lowest price. The contract will be awarded to the bidder whose proposal the Corporation determines, in its sole discretion, is the most advantageous to the Corporation and in the Corporation's best interest.

The Corporation, in its sole discretion, may, but shall not be required to, reject without further consideration the proposal of any bidder that has not demonstrated, in the Corporation’s sole judgment, that it satisfies the qualifications criteria provided in the RFP. The Corporation reserves the right, in its sole discretion and without notice to bidders, to modify this evaluation procedure as it may deem to be in the DRWC’s interest.

C.

Qualifications of personnel will be measured by experience and education, with particular reference to experience in services similar to that described in the RFP. Particular emphasis is placed on the qualifications of the project manager.

D.

SOUNDNESS OF APPROACH: Emphasis here is on the techniques, sequence and relationships of major steps, and methods for managing the service. Of equal importance is whether the technical approach is completely responsive to all written specifications and requirements contained in the RFP and if it meets the Corporation’s objectives.

E.

AVAILABLE RESOURCES: This refers to the Contractor’s financial ability, physical presence, manpower and other resources available to support the Project.

F.

M/W/DSBE PARTICIPATION. Meeting or exceeding the Corporation’s goals for equal opportunity participation as prime contractors, subcontractors or joint venture partners in bidder’s proposal, workforce diversity and use of M/W/DSBEs as vendors.

Compact until surface elevations are within tolerances specified herein and to a uniform density within range of 90 to 92 percent at optimum moisture content. Hand tamp near edges of adjoining material to avoid damage to

adjoining curbs, lawns, edge materials, and other work. Do not compact over root balls of trees and shrubs under any circumstance.

First Compaction Operation: While the stone fines mix is still thoroughly moist, roll with a heavy lawn type roller (minimum 225 pounds and maximum 30 inch width), to achieve finish grade and initial compaction. Hand tamp at edges as specified.

Second Compaction Operation: Use a heavy (1 ton minimum) small rider equipment type roller, after having initially used the lawn roller, to obtain the desired final dense, smooth, uniform texture.

Do not use wackers or vibratory rollers.

The final paving surface level shall not deviate from the design levels by more than plus or minus 1/16 inch. The surface level of the paving immediately adjacent to drainage outlets, gutter, and channels shall not deviate by more than 3/16 inch.

11. Protection: Protect the paving against traffic, injury or defacement, or damage by rain during curing period and subsequent construction operations until Final Acceptance. Keep all areas of work clean, neat and orderly at all times. Keep all adjacent planting areas clean during paving operations. After completion do not allow any traffic of any kind on the finished surface course until it is completely dried through. Curing period is dependent on weather conditions. The Contractor shall expect a period up to two weeks. The stabilized crushed stone paving must completely dry out one time before it can be put into service. e) Repairs 1. Loose gravel on the surface, or unconsolidated crushed aggregate screenings below the surface, is evidence of improper bonding due to poor mixing or insufficient watering. Test the loose material for adequate stabilizer by wetting, then tamping, and allowing it to dry. If the material is still unconsolidated, stabilizer did not get mixed adequately throughout the crushed aggregate screenings. If the material is now solid, initial watering was insufficient.

Excavate damaged area to the depth of the stabilized decomposed granite and square off sidewalls. If area is dry, moisten damaged portion lightly. Pre-blend the dry required amount of stabilizer powder with the proper amount of aggregate in a concrete mixer. Compact with an 8â&#x20AC;? to 10â&#x20AC;? hand tamp or 250 to 300 pound roller.

Keep traffic off areas for 12 to 48 hours after repair has been completed.

Any significant irregularities shall be smoothed out prior to final acceptance of work.

Smoothing shall be accomplished by rewetting/saturating rough areas thoroughly,

and then rolling the paving again with a heavy roller (2000 lbs, minimum) powered walk-behind or small rider. Wackers are not recommended. f) Acceptance 1. Finished surface of pathway shall be smooth, uniform and solid. There shall be no evidence of chipping or cracking. Dried, cured, compacted pathway shall be firm throughout profile with no spongy areas. Loose material shall not be present on the surface initially. Any significant irregularities in path surface shall be repaired to the uniformity of entire installation. e) Demonstration & Training 1. Provide demonstration and training to the Owner in the method for repairing Stone Fine Walkway.

MAINTENANCE a) Remove debris, such as paper, grass clippings, leaves or other organic material by mechanically blowing or hand raking the surface as needed. Any plowing program required during winter months shall involve the use of a rubber baffle on the plow blade or wheels on the plow that lifts the blade 1/4" off the paving surface. b) If cracking occurs, simply sweep fines into the cracks, water thoroughly and hand tamp with an 8” – 10” hand tamp plate. c) The Contractor shall monitor the site during the maintenance period and redistribute loose material, water thoroughly to a depth of 1” and re-compact with a power roller of no less than 1000 lbs. d) Warranty & Maintenance 1. Submit a written warranty executed by the installer agreeing to repair or replace components of stabilized surfacing that fail in materials or workmanship within the specified warranty period. Failures include, but are not limited to, the following: a. Premature wear and tear, provided the material is maintained in accordance with manufacturer’s written maintenance instructions. b. Improper drainage. c. Failure of system to meet performance requirements.

Cracking or sponginess is evidence of excessive organic stabilizer in the mix.

Unconsolidated areas shall be dug out, and shall be replaced with new crushed aggregate screenings with a high proportion of fines meeting the grading requirements as specified and, pre-blended to specified proportions. Patch areas then shall be wetted thoroughly and rolled smooth as specified for installations.

the definition of hazardous material or hazardous waste is not included.

3.

Debris: Non-hazardous solid material generated during the construction, demolition, or renovation of a structure which exceeds 2.5 inch particle size that is: a manufactured object; plant or animal matter; or natural geologic material (e.g. cobbles and boulders), broken or removed concrete, masonry, and rock asphalt paving; ceramics; roofing paper and shingles. Inert materials may be reinforced with or contain ferrous wire, rods, accessories and weldments. A mixture of debris and other material such as soil or sludge is also subject to regulation as debris if the mixture is comprised primarily of debris by volume, based on visual inspection.

4.

Wood: Dimension and non-dimension lumber, plywood, chipboard, hardboard. Treated and/or painted wood that meets the definition of lead contaminated or lead based contaminated paint is not included.

5.

Scrap metal: Scrap and excess ferrous and non-ferrous metals such as reinforcing steel, structural shapes, pipe and wire that are recovered or collected and disposed of as scrap.Scrap metal meeting the definition of hazardous material or hazardous waste is not included.

7.

Recyclables: Materials, equipment and assemblies such as doors, windows, door and window frames, plumbing fixtures, glazing and mirrors that are recovered and sold as recyclable. Metal meeting the definition of lead contaminated or lead based paint contaminated may be included as recyclable if sold to a scrap metal company.

Paint cans may not be included as recyclable if sold to a scrap metal company.

8.

Hazardous Waste: By definition, to be a hazardous waste a material must first meet the definition of a solid waste. Hazardous waste and hazardous debris are special cases of solid waste. They have additional regulatory controls and must be handled separately. They are thus defined separately in this document.

Material not regulated as solid waste are: nuclear source or byproduct materials regulated under the Federal Atomic Energy Act of 1954 as amended; suspended or dissolved materials in domestic sewage effluent or irrigation return flows, or other regulated point source discharges; regulated air emissions; and fluids or wastes associated with natural gas or crude oil exploration or production.

C.

015719 Page 4

E.

Garbage: Refuse and scraps resulting from preparation, cooking, dispensing, and consumption of food.

F.

Hazardous Waste: Any discarded material, liquid, solid, or gas, which meets the definition of hazardous material or is designated hazardous waste by the Environmental Protection Agency or State Hazardous Control Authority as defined in 40 CFR 260, 40 CFR 261, 40 CFR 262, 40 CFR 263, 40 CFR 264, 40 CFR 265, 40 CFR 266, 40 CFR 268, 40 CFR 270, 40 CFR 271, 40 CFR 272, 40 CFR 273, 40 CFR 279, and 40 CFR 280.

G.

Hazardous Materials: Hazardous materials as defined in 49 CFR 171 and listed in 49 CFR 172. Hazardous material is any material that: 1.

Is regulated as a hazardous material per 49 CFR 173, or

2.

Requires a Material Safety Data Sheet (MSDS) per 29 CFR 1910.120, or

3.

During end use, treatment, handling, packaging, storage, transpiration, or disposal meets or has components that meet or have potential to meet the definition of a hazardous waste as defined by 40 CFR 261 Subparts A, B, C, or D.

Designation of a material by this definition, when separately regulated or controlled by other instructions or directives, does not eliminate the need for adherence to that hazard-specific guidance which takes precedence over this instruction for "control" purposes. Such material include ammunition, weapons, explosive actuated devices, propellants, pyrotechnics, chemical and biological warfare materials, medical and pharmaceutical supplies, medical waste and infectious materials, bulk fuels, radioactive materials, and other materials such as asbestos, mercury, and polychlorinated biphenyls (PCBs).

Nonetheless, the exposure may occur incident to manufacture, storage, use and demilitarization of these items.

H.

Waste Hazardous Material (WHM): Any waste material which because of its quantity, concentration, or physical, chemical, or infectious characteristics may pose a substantial hazard to human health or the environment and which has been so designated. Used oil not containing any hazardous waste, as defined above, falls under this definition.

I.

Oily Waste: Those materials which are, or were, mixed with used oil and have become separated from that used oil. Oily wastes also means materials, including wastewaters, centrifuge solids, filter residues or sludges, bottom sediments, tank bottoms, and sorbents which have come into contact with and have been contaminated by, used oil and may be appropriately tested and discarded in a manner which is in compliance with other State and local requirements.

This definition includes materials such as oily rags, "kitty litter" sorbent clay and organic sorbent material. These materials may be land filled provided that: 1.

It is not prohibited in other State regulations or local ordinances

2.

The amount generated is "de minimus" (a small amount)

completed within 4 to 12 hours after concrete placement. Protect joints from intrusion of foreign matter.

3.3

BATCHING, MEASURING, MIXING, AND TRANSPORTING CONCRETE

ASTM C 94/C 94M, ACI 301, and ACI 304R, except as modified herein. Batching equipment shall be such that the concrete ingredients are consistently measured within the following tolerances: 1 percent for cement and water, 2 percent for aggregate, and 3 percent for admixtures. Furnish mandatory batch tickets imprinted with mix identification, batch size, batch design and measured weights, moisture in the aggregates, and time batched for each load of ready mix concrete. When a pozzolan is batched cumulatively with the cement, it shall be batched after the cement has entered the weight hopper.

A.

Measuring Make measurements at intervals as specified in paragraphs entitled "Sampling" and "Testing."

Adjust batch proportions to replicate the mixture design using methods provided in the approved quality assurance plan. Base the adjustments on results of tests of materials at the batch plant for use in the work. Maintain a full record of adjustments and the basis for each.

B.

Mixing ASTM C 94/C 94M and ACI 301. Machine mix concrete. Begin mixing within 30 minutes after the cement has been added to the aggregates. Place concrete within 90 minutes of either addition of mixing water to cement and aggregates or addition of cement to aggregates if the air temperature is less than 85 degrees F. Reduce mixing time and place concrete within 60 minutes if the air temperature is greater than 85 degrees F except as follows: if set retarding admixture is used and slump requirements can be met, limit for placing concrete may remain at 90 minutes. Additional water may be added, if both the specified maximum slump and water-cementitious material ratio are not exceeded. When water is added, an additional 30 revolutions of the mixer at mixing speed is required. If time of discharge exceeds time required by ASTM C 94/C 94M, submit a request along with description of precautions to be taken. If the entrained air content falls below the specified limit, add a sufficient quantity of admixture to bring the entrained air content within the specified limits. Dissolve admixtures in the mixing water and mix in the drum to uniformly distribute the admixture throughout the batch.

C.

Transporting Transport concrete from the mixer to the forms as rapidly as practicable. Prevent segregation or loss of ingredients. Clean transporting equipment thoroughly before each batch. Do not use aluminum pipe or chutes. Remove concrete which has segregated in transporting and dispose of as directed.

3.4

PLACING CONCRETE

Delaware River Trail Pier 70 to Washington Avenue Bulkhead Specifications

033129

Page 43

Place concrete as soon as practicable after the forms and the reinforcement have been inspected and approved. Do not place concrete when weather conditions prevent proper placement and consolidation; in uncovered areas during periods of precipitation; or in standing water. Prior to placing concrete, remove dirt, construction debris, water, snow, and ice from within the forms. Deposit concrete as close as practicable to the final position in the forms. Do not exceed a free vertical drop of 3 feet from the point of discharge. Place concrete in one continuous operation from one end of the structure towards the other or lifts for vertical construction.

A.

Vibration Comply with the requirements of ACI 309R and ASTM A 934/A 934M using vibrators with a minimum frequency of 9000 vibrations per minute (VPM). Use only high cycle or high frequency vibrators. Motor-in-head 60 cycle vibrators may not be used. Provide a spare vibrator at the casting site whenever concrete is placed. Place concrete in 18 inch maximum vertical lifts. Insert and withdraw vibrators approximately 18 inches apart. Penetrate at least 8 inches into the previously placed lift with the vibrator when more than one lift is required. Extract the vibrator using a series of up and down motions to drive the trapped air out of the concrete and from between the concrete and the forms.

For slab construction use vibrating screeds designed to consolidate the full depth of the concrete. Do not vibrate concrete placed with anti-washout admixtures. Vibrators shall be equipped with rubber vibrator heads.

B.

Application of Epoxy Bonding Compound Apply a thin coat of compound to dry, clean surfaces. Scrub compound into the surface with a stiff-bristle brush. Place concrete while compound is tacky. Do not permit compound to harden prior to concrete placement. Follow manufacturer's instructions regarding safety and health precautions when working with epoxy resins.

C.

Pumping ACI 304R and ACI 304.2R. Pumping shall not result in separation or loss of materials nor cause interruptions sufficient to permit loss of plasticity between successive increments. Loss of slump in pumping equipment shall not exceed 2 inches. Do not use pipe made of aluminum or aluminum alloy. Avoid rapid changes in pipe sizes. Limit maximum size of coarse aggregate to 33 percent of the diameter of the pipe. Maximum size of well rounded aggregate shall be limited to 40 percent of the pipe diameter. Take samples for testing at both the point of delivery to the pump and at the discharge end.

D.

Cold Weather ACI 306.1. Do not allow concrete temperature to decrease below 50 degrees F. Obtain approval prior to placing concrete when ambient temperature is below 40

Delaware River Trail Pier 70 to Washington Avenue Bulkhead Specifications

033129

Page 44

degrees F or when concrete is likely to be subjected to freezing temperatures within 24 hours. Cover concrete and provide sufficient heat to maintain 50 degrees F minimum adjacent to both the formwork and the structure while curing.

Limit the rate of cooling to 5 degrees F in any one hour and 50 degrees F per 24 hours after heat application.

E.

Hot Weather ACI 305R. Maintain required concrete temperature using Figure 2.1.5, "Effect of Concrete Temperatures, Relative Humidity, and Wind Velocity on the Rate of Evaporation of Surface Moisture From Concrete" in ACI 305R to prevent the evaporation rate from exceeding 0.2 pound of water per square foot of exposed concrete per hour. Cool ingredients before mixing or use other suitable means to control concrete temperature and prevent rapid drying of newly placed concrete. Shade the fresh concrete as soon as possible after placing. Start curing when the surface of the fresh concrete is sufficiently hard to permit curing without damage. If the evaporation rate exceeds 0.1 pounds per square foot per hour, fog spray the exposed concrete surfaces until active moist curing is applied. Provide water hoses, pipes, spraying equipment, and water hauling equipment, where job site is remote to water source, to maintain a moist concrete surface throughout the curing period. Provide burlap cover or other suitable, permeable material with fog spray or continuous wetting of the concrete when weather conditions prevent the use of either liquid membrane curing compound or impervious sheets. For vertical surfaces, protect forms from direct sunlight and add water to top of structure once concrete is set.

Internal concrete temperatures at any time during the construction shall not exceed 70 degrees C.

3.5 A.

SURFACE FINISHES EXCEPT SLAB AND PAVEMENT Defects Repair formed surfaces by removing minor honeycombs, pits greater than one square inch surface area or 0.25 inch maximum depth, or otherwise defective areas. Provide edges perpendicular to the surface and patch with nonshrink grout. Patch tie holes and defects when the forms are removed. Concrete with extensive honeycomb including exposed steel reinforcement, cold joints, entrapped debris, separated aggregate, or other defects which affect the serviceability or structural strength will be rejected, unless correction of defects is approved. Obtain approval of corrective action prior to repair. The surface of the concrete shall not vary more than the allowable tolerances of ACI 347R. Exposed surfaces shall be uniform in appearance and finished to a smooth form finish unless otherwise indicated.

E.

Topsoil Natural, friable soil representative of productive, well-drained soils in the area, free of subsoil, stumps, rocks larger than one inch diameter, brush, weeds, toxic substances, and other material detrimental to plant growth. Amend topsoil pH range to obtain a pH of 5.5 to 7.

2.2

BULKHEAD BACKFILL AND PLACEMENT See Geotechnical Report, Specification Section 01 80 00 "Reports". Suitable structural fill material should consist of sand or gravel containing less than 20 percent by weight of fines (SP, SM, SW, GP, GW), having a liquid limit less than 20 and plastic limit less than 6, and should be free of rubble, organics, clay, debris and other unsuitable material.

All structural fill and/or backfill should be compacted to a dry density of at least 98 percent of the Standard Proctor maximum dry density (ASTM D698). In general, the compaction should be accomplished by placing the fill in maximum 10-inch loose lifts and mechanically compacting each lift to at least the specified minimum dry density.

Backfill material in utility trenches within the construction areas as well as within the excavation area for the bulkhead should consist of structural fill (as described above), and should be compacted to at least 98 percent of ASTM D698. This fill should be placed in 4 to 6 inch loose lifts when hand compaction equipment is used.

Care should be used when operating the compactors near existing structures to avoid transmission of the vibrations that could cause settlement damage or disturb occupants. In this regard, it is recommended that the vibratory roller remain at least 15 feet away from existing structures; these areas should be compacted with small, hand-operated compaction equipment.

Soil Types GW, GP, SW, and SP are included in this class as specified in ASTM D 2487.

SUSTAINABILITY OF ON-SITE SOILS

2.4

See Geotechnical Report, Specification Section 01 80 00 "Reports".

The majority of the shallow subsurface soils encountered at the boring locations from the existing site grade elevations to an average depth of about 5 feet do not appear to meet the criteria recommended in this report for reuse as “structural fill”.

However, in the event that the construction areas are to remain as “green areas” and provided that the excavated soils can be properly dried, placed, and compacted, the encountered “Fill” soils (SAND; SM, SC) are anticipated to be suitable for re-use as backfill. Additionally, it is anticipated that any soils excavated on-site and proposed to be re-used as backfill, will require stockpiling and air drying in order to establish a moisture content suitable for compaction.

Soil deposits excavated at the site and noted to contain significant amounts of debris (concrete, stone, brick, etc.) should not be used as fill and/or backfill within the proposed construction areas.

2.5

BORROW Obtain borrow materials required in excess of those furnished from excavations from sources outside of the property. Dispose of materials from clearing and grubbing operations off the property.

SECTION 31 23 23.33 - FLOWABLE FILL PART 1 - GENERAL

1.1 A.

1.2

INTRODUCTION Flowable fill refers to a cementitious slurry consisting of a mixture of fine aggregate or filler, water, and cementitious material(s), which is used as a fill or backfill in lieu of compacted earth. This mixture is capable of filling all voids in irregular excavations and hard to reach places (such as under undercuts of existing slabs), is self-leveling, and hardens in a matter of a few hours without the need for compaction in layers.

Flowable fill is sometimes referred to as controlled density fill (CDF), controlled low strength material (CLSM), lean concrete slurry, and unshrinkable fill.

DESCRIPTION Furnish and place flowable fill in a fluid condition, that sets within the required time and, after curing, obtains the desired strength properties as evidenced by the laboratory testing of the specific mix design, at locations shown on the plans. This section specifies flowable fill for use as structural fill to remain permanently .

1.3 A.

1.4 A.

RELATED WORK Materials testing and inspection during construction: Section 01 45 29, TESTING LABORATORY SERVICES. DEFINITIONS Flowable fill - Ready-mix Controlled Low Strength Material used as an alternative to compacted soil, and is also known as controlled density fill, and several other names, some of which are trademark names of material suppliers. Flowable fill (Controlled Low Strength Material) differs from portland cement concrete as it contains a low cementitious content to reduce strength development for possible future removal.

Unless specifically approved otherwise, by the Engineer, flowable fill shall be designed as a permanent material, not designed for future removal. Design strength for this permanent type flowable fill shall be a compressive strength of 2.1 MPa (300 psi) minimum at 28 days. Chemical admixtures may also be used in flowable fill to modify performance properties of strength, flow, set and permeability.

Steel helmets shall fit snugly into the butt of the pile.

Placing and Driving 1.

Placing - Any excavation required within the area where sheet pilings are to be installed shall be completed prior to placing sheet pilings. Pilings shall be carefully located as shown on the contract drawings and per the reviewed detail drawings. All piles shall be installed to the minimum tip elevations specified on the plans. Pilings shall be placed plumb with out-of-plumbness not exceeding 1/8 inch per foot of length and true to line. Temporary wales, templates, or guide structures shall be provided to insure that the pilings are placed and driven to the correct alignment. At least two templates shall be used in placing each piling and the maximum spacing of templates shall not exceed 20 feet. Pilings properly placed and driven shall be interlocked throughout their length with adjacent pilings to form a continuous diaphragm throughout the length or run of piling wall. Combi-wall system king piles shall be installed in sequence recommended by the manufacturer. See manufacturerâ&#x20AC;&#x2122;s literature for driving sequence recommendations

2.

Driving â&#x20AC;&#x201C; Pilings shall be driven with the proper size hammer and by reviewed methods so as not to subject the pilings to damage and to ensure proper interlocking throughout their lengths. Driving hammers shall be maintained in proper alignment during driving operations by use of leads or guides attached to the hammer. Caution shall be taken in the sustained use of vibratory hammers when a hard driving condition is encountered to avoid interlock-melt or damages. A protecting cap shall be employed in driving when using impact hammers to prevent damage to the tops of pilings. Pilings damaged during driving or driven out of interlock shall be removed and replaced at the Contractor's expense. Pilings shall be driven without the aid of a water jet.

Adequate precautions shall be taken to insure that pilings are driven plumb. If at any time the forward or leading edge of the piling wall is found to be out-ofplumb in the plane of the wall the piling being driven shall be driven to the required depth and tapered pilings shall be provided and driven to interlock with the out-of-plumb leading edge or other reviewed corrective measures shall be taken to insure the plumbness of succeeding pilings. The maximum permissible taper for any tapered piling shall be 1/8 inch per foot of length. Pilings in each run or continuous length of piling wall shall be driven alternately in increments of depth to the required depth or elevation. No piling shall be driven to a lower elevation than those behind it in the same run except when the pilings behind it cannot be driven deeper. If the piling next to the one being driven tends to follow

Delaware River Trail Pier 70 to Washington Avenue Bulkhead Specifications

02456 Page 91

below final elevation it may be pinned to the next adjacent piling. If obstructions restrict driving a piling to the specified penetration the obstructions shall be removed or penetrated with a chisel beam. Pilings shall be driven to depths shown on the contract drawings and shall extend up to the elevation indicated on the contract drawings for the top of pilings.

C.

Cutting-Off and Splicing - Pilings driven to refusal or to the point where additional penetration cannot be attained and are extending above the required top elevation in excess of the specified tolerance shall be cut off to the required elevation. A tolerance of 1/4 inch above or below the indicated top elevation will be permitted. Splicing of pilings is not permitted. The tops of pilings excessively battered during driving shall be trimmed when directed at no cost to the Owner. Piling cut-offs shall become the property of the Contractor and shall be removed from the site. The Contractor shall cut holes in pilings for bolts, rods, drains or utilities as shown or as directed. All cutting shall be done in a neat and workmanlike manner. A straight edge shall be used in cuts made by burning to avoid abrupt nicks. All welding shall be performed in accordance with the Structural Welding Code of the American Welding Society, (AWS D1.1).

DELAWARE RIVER WATERFRONT CORPORATION CONFLICT OF INTEREST DISCLOSURE CERTIFICATION

The Delaware River Waterfront Corporation ( “DRWC ”) exists to promote redevelopment along the Delaware River waterfront to benefit the City of Philadelphia and all of its citizens, regardless of race or economic status.

To effectively carry out this mission, the DRWC and its Directors, Officers, and Employees have an absolute obligation to uphold the public trust. In connection with its operations and activities, the DRWC is open, transparent and accountable to the public and to the City of Philadelphia. It strives to earn a reputation for honesty, fairness, and judicious use of public and private funds.

To that end, DRWC requests that the respondent/bidder certify that it does not have any professional engagements (including, but not limited to contracts or grants), relationships (including, but not limited to fiduciary, familial, marital, property or any other relationship that might result in a conflict of interest), conflicts of interest, or potential conflicts of interest with any DRWC Director, Officer, or Employee.

If the respondent/bidder is uncertain whether or not a relationship could be considered to be a conflict of interest or potential conflict of interest, the matter in question should be disclosed.

Disclosure of a conflict of interest or potential conflict of interest will not necessarily preclude the respondent/bidder from consideration.

To the best of our knowledge, no conflict of interest or potential conflict of interest exists that would impact our involvement in this project.

A conflict of interest or potential conflict of interest is disclosed and more fully reported in the proposal/bid under the “Disclosure Statement ” section.
