The actual amounts requested by municipalities will be based on funding and other factors related to the work. This is a unit price contract and the contract will be awarded to the contractor with the lowest bid based on all the listed items as calculated in the total cost line item. The quantity numbers in the bid form are only for bidder comparison to determine the lowest bidder. It is understood that the contractor will provide the quantities actually required by the municipalities. Because these services are procured on an as-needed basis, contractors will be required to provide a written estimate of the project cost based on the bid pricing when requested to provide a specific service for a municipality.

INVESTIGATION OF CONDITIONS

Bidders are expected to visit the locality of the work and acquaint themselves with all available information concerning local conditions. They are also expected to make their own estimates of the facilities needed and difficulties attending the execution of the proposed Contract including local conditions, availability of labor, uncertainties of weather and other contingencies. In no event will the municipalities take any responsibility whatsoever for any interpretation, deduction or conclusion drawn from the inspection of the work site. Failure to acquaint oneself with all available information concerning these conditions will not relieve the successful bidder from responsibility for estimating the difference and costs of successfully performing the complete work.

Questions regarding site specific work in a municipality should be addressed to the appropriate contact person in that municipality, as identified in this bid package.

Any bidder finding ambiguity, inconsistency, or error shall promptly notify the SERSG Procurement Officer of such.

AWARD CRITERIA

The Board of Directors of the Southeastern Regional Services Group will recommend to the Awarding Authorities of each City or Town participating in this procurement award to the lowest responsible and eligible bidder for each Item of Work. Bids will be rejected that fail to provide prices for all work included in one Item. Alternative or conditional bids will not be considered nor will bids that are not the same for all municipalities for an Item, except for items that are priced by Zone. A contract will be awarded to the lowest responsible and eligible bidder for each Item of Work by each participating municipality, as defined in DETERMINATION OF LOWEST BID below.

Bidders may bid on one or more items of Work and contracts may be awarded to one or more bidders based on a determination that said bidder or bidders are the lowest responsible and eligible bidder for each item of Work.

Each bid on each item of Work will be addressed separately, and bidders are not required to bid on all items.

Bidders who submit unrealistically low bids may be deemed not responsible and may result in a bidder being unresponsible and ineligible for that item.

The SERSG Board of Directors reserves the right to waive any informality or reject any or all bids.

BRAND NAME or EQUAL

Unless otherwise specified in this IFB, any reference to a particular trademark, trade name, patent, design, type, specification, producer or supplier is not intended to restrict this IFB to any manufacturer or proprietor or to constitute an endorsement of any commodity or service, and the department may consider clearly identified offers of substantially equivalent commodities and services submitted in response to such reference.

DETERMINATION OF LOWEST BID PRICE

The lowest bid shall be determined on the basis of the total price for which the entire Work in each Item will be performed. Prices quoted in Appendix A should include all materials and services specified in this IFB. The participating municipalities are exempt from the payment of taxes and no taxes should be included in the bid price. Bidders may bid on any number of Items. The lowest responsible and eligible bidder will be determined separately for each Item of Work. Contractors must bid for all the sub-items of work included in one Item of Work.

The estimated quantities for each sub-item will be multiplied by the unit price to achieve a total amount for that sub-item. Then, the total amounts for all the sub-items will be totaled to reach a total bid price for each Item of Work. Each contractor’s total bid price for the same Item of Work will be compared to the other bidders' total bid prices to determine which is lowest.

For Item One Pavement Reclamation and Item Twenty-Eight Sidewalks, the lowest bidder for each municipality will be determined by multiplying each municipality’s quantities of items and sub-items by the prices bid for those items. Contractors with the lowest total price for each municipality will be awarded that municipality’s contract.

For Item Seventeen, Structure Work, the lowest bid will be determined by calculating the average cost of each of the categories of work, as outlined in this item’s Specification. The bidder with the lowest average price will be deemed to be low bidder.

Bidding one penny on a sub-item of work is only allowed when such bidding does not render the bid unbalanced.

An unbalanced bid is defined as one containing an abnormally low price for one item and an abnormally high price for another item in order to recoup losses from the abnormally low price. Contractors who bid one penny will be fully expected to perform the sub-item of work for that price.

REJECTION OF BIDS

Bids that fail to meet the requirements of the Invitation may be rejected. Bids that the Procurement Officer, in his sole discretion, determines to be incomplete, conditional or obscure, or which contain additions not called for, erasures, alterations or irregularities of any kind, may be rejected. Bids in which errors occur, or which contain abnormally high or abnormally low prices for any Total Bid Price for any Item of Work shall be declared non-responsive. If the Procurement Officer deems it to be in the best public interest, the SERSG Board may waive any or all informalities as to form. Informalities as to substance, however, shall not be waived. In cases of ambiguity of bid prices, the unit price will prevail over the total price listed.

METHOD TO BE USED TO AWARD A CONTRACT WITH TIE BIDS

Should there be two or more low bids for the Contract to be awarded which are identical and where the bidders are determined to both be responsible and eligible in accordance with M.G.L. Chapter 30, Section 39, the following procedure shall be used to award the Contract:

a. The Contract will be awarded to that bidder with its office located within the SERSG region.

b. If there is no bidder with its office located within the SERSG region or if there are two or more bidders with offices located within the SERSG region, the award of the Contract shall be determined by a toss of a coin. Such a toss shall be done in the presence of the respective bidders.

c. If there are more than two bidders with identical bids, the coin toss method shall be used by selecting the first two bidders in alphabetical order and eliminating one with a coin toss. This process shall be continued until such time as there remains one bidder.

PREVAILING WAGE

The Department of Labor Standards established county wage tables provided in this document. These wage rates must be paid to all workers employed on the Contract and are the minimum rate of wages allowable for payment to workers on this contract throughout the terms of the Contract.

Beginning with new contracts resulting from this 2027 bid, Prevailing Wage Tables are provided for each county and must be paid for all towns/cities within that county. A list of SERSG-member towns by county is provided in Attachment 3: Prevailing Wage Rates.

The Contractor shall not have any claim for extra compensation from if the actual wages paid to employees on the Contract exceeds the rates listed on the schedule. The Contractor shall cause a copy of said Schedule to be kept in a conspicuous place at the Project site during the term of the Contract. (See M.G.L. c.149 §27).

WAGE RATE CHANGES

The Director of the Department of Labor and Workforce Development has established the wage rates established for this contract for a one (1) year period. On the option years of this contract, if extended pursuant to a contract extension, new wage rates shall be established pursuant to a new requirement of said department. If additional contract years are exercised by Awarding Authorities the new changes (difference) will be allowed in bid price for contract extension. The difference is the increase only in the updated prevailing wages from the previous year. No other costs will be allowed.

LABOR AND MATERIALS PAYMENT BOND

Within ten days of receipt of notification of the start of work, the bidder awarded a contract must pay for and furnish each Awarding Authority with a Labor and Materials Payment Bond in the sum of fifty percent (50%) of the estimated contract value. Such bonds must be issued by a surety company incorporated pursuant to section 105 of Chapter 175 of the M.G.L. or by a surety company authorized to do business in the Commonwealth under the provisions of section 106 of Chapter 175 of the M.G.L. and be approved by the U.S. Department of the Treasury and be acceptable as a surety and reinsurer on Federal bonds under Title 31 of the United States Code, Sections 9304 to 9308. Payment bonds issued by foreign companies must be counter-signed by the lawfully constituted and licensed resident agent of the company in the Commonwealth. These bonds shall list each Awarding Authority separately on its face. These bonds must be maintained in force until one year after the completion of the Contract Term.

The Contractor shall be required, as work totaling more than the estimated contract value has been assigned, to increase the amount of the payment bond in a manner such that the total amount of the payment bond shall be equal to at least fifty percent (50%) of the total dollar value of the Contract to date.

LIQUIDATED DAMAGES

Failure or refusal of the successful bidder to execute and deliver a signed contract, Certificate of Insurance and Labor and Materials Payment Bond acceptable to the Procurement Officer within ten days after notice of contract award will result in forfeiture of the Bid Bond as liquidated damages.

HEALTH AND SAFETY

The successful contractor shall fully comply with Chapter 306 of the Acts of 2004. This act is relative to the health and safety on public construction projects and work.

PRICE ADJUSTMENTS

The index for all price adjustments can be found at https://www.mass.gov/service-details/massdot-current-contract-price-adjustments . All adjustments will be made based on the December 2023 price posted for each of the following products.

DIESEL FUEL PRICE ADJUSTMENT

Adjustments due to changes in cost of diesel fuel will be calculated as follows. The adjustment is to be based on the increase or decrease of diesel fuel cost, as measured by the U.S. Department of Energy, Energy Information Administration baseline cost of diesel fuel determined on the date of the bid. The increase or decrease, as determined above, will be applied to the volume of fuel used which will be determined based on fuel consumption agreed on by each municipality. Adjustments will be made monthly, based on the cost of diesel for the month used. It shall be the contractor’s responsibility to provide each municipality with full documentation prior to fuel adjustments being accepted.

LIQUID ASPHALT PRICE ADJUSTMENT

This adjustment will provide for either additional compensation to the Contractor or repayment to the municipality depending on an increase or decrease in the average price of liquid asphalt. This provision applies to all products containing liquid asphalt. The Base Price of Liquid Asphalt on the project will be a fixed price determined on the date of the bid. The price adjustment will be based on the variance in price for the Liquid Asphalt component only from the Base Price to the Period Price. It shall not include transportation or other charges. The Period Price for any products including liquid asphalt for a 30-day period will be determined and published by the Massachusetts Highway Department by averaging the prices posted at the beginning, middle, and end of each two-month period by two or more suppliers.

The Contract Price of the product will be paid under the respective item in the contract. The price adjustment, as herein provided, upward and downward, will be made as work is performed, using the most recent previous price adjustment Item until the applicable Period Price is established. The asphalt content for each item is set forth in the specifications.

The Price Adjustment will be a separate payment item. It will be determined by multiplying the number of tons of product placed during each previous 30-day period by asphalt content percentage times the variance in price between Base Price and Period Price of asphalt. Contractors must include price adjustment documentation with every invoice. No price adjustment will be allowed beyond the completion date of the contract, unless there is an approved extension of time by the municipality.

PORTLAND CEMEMT PRICE ADJUSTMENT

The municipality will use the Massachusetts Department of Transportation, Highway Division procedure for price adjustment for Portland cement as outlined in Document 00814, "Special Provisions: Price Adjustment for Portland Cement Concrete Mixes," January 12, 2009. The price adjustment will be based on the variance in price for Portland cement from the base price to the period price.

ITEM TWO: COLD IN-PLACE RECYCLING

PART 1 – CORE SAMPLING

1. DESCRIPTION

Core sampling and mix design are required to determine a road(s) viability for the Cold In-place Recycling process.

It is also an optional process to assess existing road conditions.

Whenever core sampling is done, a report of findings shall be provided to the awarding authority prior to invoicing for any work under this item.

Cores shall be obtained using a pattern that results in a representative sample of the pavement to be recycled including at or near lane lines, within and between wheel paths, at the pavement edge, and within shoulders, if shoulders are to be recycled. The roadway shall be sampled in accordance with staggered or offset sampling (as illustrated in Diagram 1a) or crossroad sampling with no offset (as illustrated in Diagram 1b).

Core samples shall be obtained to the underlying base or subgrade soil. If a core breaks off prior to penetrating the underlying materials, coring shall continue to the bottom of the pavement for thickness measurement purposes.

On retrieval, each core shall be measured to the nearest 1/8th inch, and then placed in a separate container and labeled. A coring log summarizing the date, station, offset, and core thickness shall be recorded for each core location and provided to the mix design laboratory.

D – 1 mile maximum L – 0.5 mile maximum

a) At least 15% of the cores shall be in the shoulder, if the shoulder is getting recycled.

b) At least 25% of the cores shall be on or within 3 feet of centerline.

Arterial and Industrial Streets

D – 2,000 feet maximum L – 1,000 feet maximum

a) At least 25% of the cores shall be in the shoulder, if it is getting recycled, or within 3 feet of gutter.

b) At least 25% of the cores shall be on or within 3 feet of centerline.

Residential Streets

a) For streets less than 250 feet long, a minimum of one core when grouped with other streets to obtain the quantity of material required for mix design.

b) For streets 250 feet to 500 feet long, a minimum of two cores when grouped with other streets to obtain the quantity of material required for mix design (one within 3 feet of gutter, and the other within 3 feet of centerline).

c) For streets over 500 feet long, a minimum of three cores when grouped with other streets to obtain the quantity of material required for mix design (one within 3 feet of gutter, one within 3 feet of centerline, and the third between the two).

2. FILLING SAMPLE HOLES

a) Each sample hole shall be filled in accordance with the procedures described below. After sampling and filling the holes, the roadway shall be cleaned of all loose debris.

b) A high quality cold patch material shall be used to fill core or milling holes. The cold mix shall be compacted flush with a tamping rod, sledge or Marshall hammer. Approximately the same amount of cold patch (350lbs) will be required to fill the holes as is required for each mix design.

3. MEASURE AND PAYMENT

a) Under the unit bid price, the Payment for Core Sampling shall be per each day of Core Sampling regardless of how many samples are required in an 8 hour day. More than one street may be included in the eight hour day described.

b) Core Sampling will not be paid without a written report to the Owner detailing the amount of samples collected, the locations of the samples and the results of the sampling.

5) Construct control strips using equipment and methods representative of the operations to be used for constructing the CIR layer.

6) After compacting the control strip with a minimum of 2 passes, mark and take density measurements at 3 random locations, at least 1½ feet from the edge of the CIR layer. Take subsequent density measurements at the same 3 locations.

7) After each subsequent pass of compaction equipment over the entirety of the control strip, take density measurements at the 3 marked locations. Continue compacting and testing until the increase in density measurements is less than 2.0 lb/cubic feet, or the density measurements begin to decrease.

8) Upon completion of control strip compaction, take 10 randomly located density measurements within the limits of the control strip, at least 1½ feet from the edge of the base. The final measurements recorded at the 3 locations under paragraph (6) of this section may be included as 3 of the 10 measurements.
