The appropriate blanks in Section A below must be filled out by all out-of-state or non-resident bidders in order for your bid to meet specifications. The failure of out-of-state or non-resident contractors to do so will automatically disqualify that bidder. Resident bidders must check the blank in Section B. A.

CI - 1 INSURANCE REQUIREMENTS AND WORKERS’ COMPENSATION REQUIREMENTS Respondent’s attention is directed to the insurance requirements below. It is highly recommended that respondents confer with their respective insurance carriers or brokers to determine in advance of Proposal/Bid submission the availability of insurance certificates and endorsements as prescribed and provided herein. If an apparent low respondent fails to comply strictly with the insurance requirements, that respondent may be disqualified from award of the contract. Upon contract award, all insurance requirements shall become contractual obligations, which the successful contractor shall have a duty to maintain throughout the course of this contract.

As soon as practicable after notification of bid award, Contractor shall file with the Purchasing Department satisfactory certificates of insurance including any applicable addendum or endorsements, containing the bid number and title of the project. Contractor may, upon written request to the Purchasing Department, ask for clarification of any insurance requirements at any time; however, Contractors are strongly advised to make such requests prior to proposal/bid opening, since the insurance requirements may not be modified or waived after proposal/bid opening unless a written exception has been submitted with the proposal/bid.

All insurance policies proposed or obtained in satisfaction of these requirements shall comply with the following general specifications, and shall be maintained in compliance with these general specifications throughout the duration of the Contract, or longer, if so noted: • Each policy shall be issued by a company authorized to do business in the State of Texas with an A.M.

The inclusion of more than one insured shall not operate to increase the insurer's limit of liability. • All policies shall be endorsed to read: “Cancellation: City requires 30 day written notice should any of the policies described on the certificate be canceled or materially changed before the expiration date.” • Should any of the required insurance be provided under a claims-made form, Contractor shall maintain such coverage continuously throughout the term of this contract and, without lapse, for a period of three years beyond the contract expiration, such that occurrences arising during the contract term which give rise to claims made after expiration of the contract shall be covered. • Should any of the required insurance be provided under a form of coverage that includes a general annual aggregate limit providing for claims investigation or legal defense costs to be included in the general annual aggregate limit, the Contractor shall either double the occurrence limits or obtain Owners and Contractors Protective Liability Insurance. • Should any required insurance lapse during the contract term, requests for payments originating after such lapse shall not be processed until the City receives satisfactory evidence of reinstated coverage as required by this contract, effective as of the lapse date.

TIME ALLOTTED FOR COMPLETION The number of days for the Base Bid for this project is shown on the Bid Tabulation Sheets to be nine hundred (900) calendar Days for substantial completion. Substantial completion is defined as all roadway lanes paved and open to traffic (with temporary tabs) and all sidewalks and ramps open for pedestrian use. The project is to be complete in nine hundred thirty (930) consecutive calendar days from start of construction for all manners of construction and project documentation. The Contractor is permitted to work every weekday which is not a Federal, State or Local holiday from 7:00 am to 6:00 pm. Work requiring City inspection oversight must be restricted to the hours between 8:00 am to 5:00 pm unless arrangements are made with the City beforehand. The Contractor will not be allowed to work on Saturdays unless prior arrangements are made with the City. The Contractor will not be allowed to prosecute the work on Sundays without written permission by the City due to the noise ordinance. Exceptions to the noise ordinance require approval by City Council and will require careful coordination and planning between the Contractor and City. A Work Order shall be submitted by the City to the Contractor prior to the beginning of construction. A Work Order shall consist of a written request by the City Engineer for the Contractor to proceed with the construction of the project. The Work Order shall specify the starting and ending date of the G-3 project construction.

MATERIAL SAMPLING AND TESTING Unless otherwise stipulated in the contract documents, initial testing of all materials, construction items or products incorporated in the work shall be performed at the direction of the City Engineer and expense of the City, including initial compaction and density tests deemed necessary. In the event materials, construction items or products incorporated in the work fail to satisfy the minimum requirements of the initial test, appropriate prove-out test shall be made as directed by the City Engineer to determine the extent of the failure and to verify that the corrective measures have brought the item up to specification requirements. The cost of all testing necessary to determine the extent of the failure and the adequacy of the corrective measures shall be the responsibility of the Contractor. The failure of the City Engineer to direct the City to make any tests of materials shall in no way relieve the Contractor of his responsibility of furnishing materials conforming to the contract documents. Tests, unless otherwise specified, shall be made in accordance with the latest methods of the American Society for Testing and Materials. The Contractor shall provide such facilities as the City Engineer or City may require for collecting and forwarding samples and shall not use the materials represented by the samples until tests have been made.

G-7 The inspections and tests made by the city shall ordinarily be made without cost to the Contractor unless otherwise expressly specified in the contract documents. The Contractor shall furnish without additional cost to the City Engineer or City such materials for testing as may be reasonably necessary. Retesting after failure to pass tests shall be at the expense of the Contractor.

Containing small cavities, usually lined with a mineral of different composition from that of the surrounding rock. Containing numerous small, unlined cavities, formed by expansion of gas bubbles or steam during solidification of the rock. Containing pores, interstices, or other openings which may or may not interconnect. Containing cavities or caverns, sometimes quite large. Most frequent in limestones and dolomites. Void Cavities Vuggy Vesicular Porous Cavernous Very Close CloseMedium Close Wide <2" 2"-12" 12"-3'>3' SPACING SOLUTION AND VOID CONDITIONS Highly Weathered Limestone Weathered Limestone Limestone Dolomite ROCK TYPES Weathered Shale Shale Slightly Moderately Highly Completely Residual Soil Discoloration indicates weathering of rock material and discontinuity surfaces. Less than half of the rock material is decomposed or disintegrated to a soil. More than half of the rock material is decomposed or disintegrated to a soil. All rock material is decomposed and/or disintegrated into soil. The original mass structure is still largely intact. All rock material is converted to soil. The mass structure and material fabric are destroyed.
