15211

dividing the total actual score by the total possible score. The contractor with the lowest proposed Base Proposal price plus selected Alternates and an evaluation grade of 80% or better will be ranked as the number one firm with each of the higher priced contractors (with a score of 80% or higher) given ranking of 2nd, 3rd, 4th, etc. In the event that no contractor receives a grade of 80% or better, the district at its option, will lower the minimum grade required in increments of 5% points as they deem to be needed and negotiate with those contractors in rank order of price. 2. The Owner may make such investigations as he deems necessary and request additional information from the contractor to determine the ability of the proposer to perform the Work. The Proposer shall furnish all such information and data for the purpose as may be requested. The Owner reserves the right to reject any proposal if the evidence submitted by, or investigation of, such proposer fails to satisfy the Owner that such proposer is properly qualified to carry out the obligations of the Contract and to complete the Work contemplated above. 3. A committee consisting of Bryan ISD administrators, the Engineer, and other staff will make an initial evaluation of the proposals to determine the number one ranked firm. Its recommendation will be considered by the Bryan ISD Board of Trustees (“Board”). The district reserves the right to review the recommendation with the Board of Trustees Facilities Committee prior to review by the entire Board of Trustees. The final decisionmaking authority has not been delegated to any person or entity other than the Board. 4. By submitting a proposal, each proposer agrees to waive any claim it has or may have against the Owner, the Architect/Engineer, and their respective employees, arising out or in connection with the administration, evaluation, or recommendation of any proposal; waiver of any requirements under the Proposal Documents or the Contract Documents; acceptance or rejection of any proposals; and award of the Contract. 1.21

USE OF ASBESTOS FREE MATERIALS, PRODUCTS AND SYSTEMS A.

1.22

The Offeror is reminded to refer to the Paragraph above for requirements during the Proposal period and the following requirements during performance of the Work regarding the use of asbestos free materials, products and systems in the Project. 1. Since many materials, products and systems are proprietary, it is not possible to know all of the materials or components which go into producing such material, product or system without the manufacturer divulging trade secrets or patent information. Every effort has been made to specify materials, products or systems, which either as an "off the shelf" material, product or system or as a custom material, product or system do not contain asbestos. 2. It is the Contractor’s responsibility to submit an affidavit from the manufacturer to ascertain that every material, product or system used in the Project does not contain asbestos. In the event the material, product or system is found to contain asbestos, the Contractor shall offer for the Architect’s consideration a substitution which he knows does not contain asbestos. 3. Even though a material, product or system is specified or a specification is based on a particular material, product or system, the Contractor will not be relieved from the responsibility to ascertain that materials, products and systems used in the Project do not contain asbestos. Under no circumstances shall a material, product or system which is known, suspected or found to contain asbestos be used on the Project. 4. If a material, product or system containing asbestos is used, the Contractor shall remove and replace the material, product or system with one which is asbestos free at no additional expense to the Owner, including removal and replacement of other materials affected by the removal of the asbestos bearing material, product or system, i.e. gypsum wallboard removed, replaced, and repainted on account of insulation being removed, etc.

If any part of Contractor’s work depends for proper execution or proper results on the work of any other separate contractor, Contractor shall inspect and promptly report in writing to the A/E any discrepancies or defects he may find in such other work that render it unsuitable for such proper execution and results. Failure of Contractor to so inspect and report shall constitute acceptance of the other contractor’s work as fit and proper to receive his work, except as to defects which may develop in the other separate contractor’s work after the execution of Contactor’s work.

C.

Should Contractor cause delay or cause damage to the work or property of any separate contractor on the Project, Contractor shall, upon due notice, endeavor to settle with such other contractor by agreement.

D.

The Contractor shall afford the Owner and separate contractors reasonable opportunity for introduction and storage of their materials and equipment and performance of their activities and shall connect and coordinate the Contractor’s construction and operations with theirs as required by the Contract Documents.

GENERAL A.

It is the responsibility of the Contractor to utilize whatever techniques are necessary to address erosion problems as they occur during construction.

B.

Siltation control and sediment trapping devices shall be installed prior to site clearing, grading or utility construction operations. All devices should be positioned so as to effectively remove silt from storm water before it leaves the site. Of particular concern, are gravel or stone blankets placed at construction traffic exits and entrances. These controls should be closely monitored to see that they trap sediment before it reaches the existing street and drainage system.

C.

Construction activities should be phased to expose a minimum of graded area at one time. Earth exposed by the construction process shall be re-vegetated every two weeks until vegetation is established. Re-vegetation shall require seeding, hydromulching or sodding. Fresh growth of vegetation shall eliminate the need for additional re-vegetation but does not constitute stabilization.

D.

Should a construction process remove any portion of the perimeter controls, the controls should be replaced in accordance with the TCEQ guidelines. Prior to the completion of the project, all bare areas shall be re-vegetated with a cellulose fiber hydromulch seeding process or sodded.

E.

Siltation control devices placed at storm drain inlets and culverts shall be removed by the Contractor once the site has been stabilized.

MAINTENANCE AND INSPECTION A.

The contractor shall familiarize himself with the erosion control requirements of TCEQ. The site superintendent, or his representative, shall make a visual inspection of all structural and/or natural controls and newly stabilized areas as required by TCEQ, especially after a rainfall to insure that all controls are maintained and properly functioning. Any damaged controls shall be repaired prior to the end of the work day, including re-seeding and mulching or re-sodding if necessary. All inspections shall be documented with a written report. Reports shall include the effectiveness of erosion control measures, construction activities conducted since the last report and their location. Reports shall be maintained by the Contractor along with the Erosion Control Plan per the TCEQ guidelines.

B.

The contractor is responsible for the ECP. The contractor shall continuously update the plan with all changes. Areas already stabilized shall be noted on the plan. All sediment trapping devices shall be installed as soon as practical after the area has been disturbed (never more than 14 days). All sediment trapping devices shall be cleaned when the sediment level reaches 25% capacity. Sediment shall be disposed of by spreading on site or hauling away if not suitable for fill. 2

Section 31 25 13 Erosion and Sedimentation Control

C.

The Contractor shall be responsible for any and all materials, improvements, and maintenance activities necessary to keep dust, silt, and mud from leaving the work zone, including being tracked by vehicles traveling throughout the zone.

D.

Should, in the opinion of the Owner, the Contractor fail to prevent the escape of dust or contain silt and mud within the project, after due notification by the City Representative, Owner forces will be used to clean up those affected areas, and the cost of same will be deducted from the contract.

E.

Prior to Substantial Completion, the Contractor shall verify that no dust, silt, or mud exists within the work zone in deposits deeper than two inches (2”) as a result of the contractor’s containment procedures. Should the Contractor claim final completion without removing such deposits, they will be removed by Owner forces and the cost of which shall be deducted from the contract.

Surfaces shall be crowned or sloped per plans to provide adequate drainage. 3. Curbs and gutters: Construct as detailed on drawings. 4. Paving Drive approaches: Construct as detailed on drawings. 5. Refer to drawings for any miscellaneous items and construct as detailed. B. Reinforcement 1. Install all reinforcing to meet the details on the drawings. 2. Minimum reinforcement at paving, parking and flatwork shall be #4 bars at 16” on center each way, unless noted otherwise on the drawings. C. Concrete: 1. Place concrete to meet the requirements of the drawings. 2. Place concrete in accordance with ACI 301 and 304. Deposit concrete so that specified slab thickness will be obtained after vibrating and finishing operations. Minimize handling to prevent segregation. Consolidate concrete by suitable means to prevent formation of voids or honeycombs. Exercise care to prevent disturbance of forms and reinforcing and damage to vapor retarder. Place concrete to lines and levels shown, properly sloped to drain into adjacent yard areas and drainage structures. 3. Hot Weather Placement: ACI 305. 4. Cold Weather Placement: ACI 306. 5. Ensure reinforcement, inserts, embedded parts, and formed joints are not disturbed during concrete placement. 6. Place concrete continuously between predetermined construction joints. Do not break or interrupt successive pours such that cold joints occur. D. Expansion Joints 1. Locate expansion joint around fixed objects within or abutting concrete, and as shown on the plans along drive and parking areas. 2. Install Preformed filler with top edge approximately ¼” below the finished concrete surface to a neat, straight joint. 3. Joints shall be ¾” to 1” wide unless detailed otherwise on the drawings. All joint edges shall be rounded with an edging tool to provide an acceptable finished appearance. 4. There shall be no connection by reinforcement or keyway across expansion joints. Joints shall be held in alignment with sleeved, smooth dowels where required. E. Scoring: 1. Saw cut walks, approaches, and paving using and abrasive or diamond blade. Cut joint width shall be ½” and depth shall be ¼” deep at walks and ¼ total slab thickness, unless detailed otherwise on the drawings, at approaches, drives and paving. Cutting of joints shall be done as soon as the concrete surface is firm and will not be damaged by the blade (4-12 hours of finish) and before shrinkage cracks have the ability to form in the concrete slab. 2. Score walks at approximately 5’-0” intervals in each direction unless specified otherwise on the drawings. Where walks abut curbs, control joint cuts shall align. CONCRETE PAVING 32 13 13 - 2
