This prohibition does not apply when the interest is represented by ownership of stock in a corporation involved, provided such stock ownership amounts to less than one percent (1 %) of the corporation stock. Any violation of this prohibition will constitute malfeasance in "- office. Any officer or employee of the City found guilty thereof should thereby forfeit his office or position.

ITEM 1.58 - STATE AND LOCAL SALES AND USE TAXES SC -1.58 Delete Item 1.58 and substitute the following in lieu thereof: 1.58 Recent legislation has removed the sales tax exemption previously provided by Section 151.311 of the Tax Code covering tangible personal property purchased by a contractor for use in the performance of a contract for the improvement of City-owned realty. It is still possible, however, for a contractor to make tax -free purchase of tangible personal property, which will be incorporated into and become part of a City construction project through the use of a "separated contract" with the City. A "separated contract" is one, which separates charges for materials from charges for labor. Under such a contract, the contractor becomes a "seller" of those materials, which are incorporated into the project, such as bricks, lumber, concrete, paint, etc. The contractor issues a resale certificate in lieu of paying the sales tax at the time such items are purchased. The contractor then receives an exemption certificate from the city for those materials. (This procedure may not be used, however, for materials, which do not become a part of the finished product. For example, equipment rentals, form materials, etc. are not considered as becoming "incorporated" into the project). 3 -7 Standard Specifications Supplementary Conditions Utilization of this "separated contract" approach eliminates the need for bidders to figure in sales tax for materials, which are to be incorporated into the project. The successful bidder's bid form will be used to develop the "separated contract" and will determine the extent of the tax exemption. Upon execution of the construction contract, the contractor shall furnish a breakdown (per item) of 1) materials incorporated into the project; and 2) labor, equipment, supervision and materials not incorporated into the project.

(b) Earth Bedding: Add the following sentence at the beginning of this paragraph: "Barth bedding will not be permitted without written approval of the Engineer." ITEM 2.2.2 - CHEMICAL ADMIXTURES (d) Mineral Admixtures. Delete paragraph (d) in its entirety.

PART III DIVISION 4 - SUBBASE AND BASE COURSES ITEM 4.8.4 - CONSTRUCTION METHODS (b) Compaction Amend the last sentence of the first paragraph, by striking the words: "90 percent of the maximum dry density of such material." and replace with the words "95 percent of the _ maximum dry density of such material, or as directed by Engineer. PART III DIVISION 5 - PAVEMENT /SURFACE COURSES ITEM 5.8.2 - (e) Joints (1) Expansion Joints: Delete the first paragraph and replace with the following: "Expansion joints shall be installed perpendicularly to the surface and centerline of the pavement. Expansion Joint material shall be redwood boards, 3/4 -inch in width, and extended through curbs. Expansion joints are to be installed at each end of radius at street intersections. Expansion joints shall be equally spaced between intersections with not less than one every 200 linear feet of pavement, unless otherwise specified on the Plans or directed by the Engineer. 3 -9 Standard Specifications Supplementary Conditions (C) Proximity to Existing Structures: Add to end of sentence, "or as directed by the Engineer ". (2) Contraction Joints. Delete the first sentence of the first paragraph and insert the _ following: "Contraction or dummy joints shall be sawed to 1 -1/4 inches in depth, and 1/4 inch in width, and installed every 20 linear feet of pavement, and extend through curb, unless otherwise directed by the Engineer." (h) Finishing. (1) Machine.

The display may be scrolled or paged down to display the next eight phase bank, additional intervals, or related information. 2.7.2.3 The controller unit shall have a copy mode, allowing the user to easily copy programmed interval information into remaining phases. 2.7.2.4 In addition to TS 2 Section 3 requirements, the following modes shall be available on a per phase basis: 1) Conditional Re- service 2) 3) 4) 5) 6) 7) Walk Clearance through Yellow Skip Red Interval if no call in Yellow Red Rest Max II Allow conflicting phases, 2 entries per phase Next Phase if power up in the Yellow Interval 2.7.2.5 The following configurations, as a minimum, shall be programmed within the controller unit and be user selectable: 1) User Mode defined by the operator 2) 8 Phase NEMA 3) 8 Phase Sequential 4) NEMA phasing to the left of barrier, sequential phasing to the right of barrier (Quad Sequential). 5) 4 Phase Diamond Interchange 6) 3 Phase Diamond Interchange 7) Separate Intersection — (2) four -phase intersections 2.7.2.6 The controller shall have a configuration which allows a minimum of 4 user programmable rings (compatibility lines, reference points to assure there shall be no concurrent selection and timing of conflicting phases). 2.7.2.7 The controller shall have programmable conflicting phase settings where simultaneous operation of compatible phases is not allowed. 6-18 Technical Specy7catlons & Description of Pay Items 2.7.2.8 A Phase Dynamic Maximum operation which increments the current maximum in -- programmable steps (Dynamic Max Step) in seconds to a maximum limit (Dynamic Max Limit) in seconds shall be provided. The operation shall function as defined by TS 3.5 §2.2.2.18. 2.7.2.9 The TBC shall select and coordinate reversible left turn sequence operations (dual leading, leading and lagging, or lagging and leading left turns). It shall be possible to transfer operation from one sequence to another at a preprogrammed time. Transfer shall take place at To during coordination (see paragraph 2.7.4.2). 2.7.3 Coordination _ 2.7.3.1 A minimum of 64 timing patterns, each with a unique cycle length and offset combination, shall be available. Each of the 64 timing patterns will select one of the 16 possible split plans. Cycle length selections are to be each changeable from 30 to 255 seconds, in one - second increments. Phase split times and offset selections are to be adjustable from 0 to 254, in 1- second increments. 2.7.3.2 The coordinator shall reference a system -wide reference cycle timer (system cycle timer). The term To shall refer to the point in the local cycle timer when the first coordinated phase (or leading coordinated phase if a pair of coordinated phases was selected by the user) is scheduled on for the first time. Note, this may not be the beginning of Green in the case of early return. The offset shall be the time in seconds that the local cycle timer lags the system cycle timer. For example, if the offset is +10 seconds, To (the point at which the local cycle timer is at 0) will occur when the system cycle timer is at 10 seconds. 2.7.3.3 An entry shall be provided that will allow the automatic modes of coordination to reference either the beginning of the coordinated phase to local cycle zero or reference the end of the coordinated phase to local cycle zero. 2.7.3.4 The controller shall contain the two modes of automatic coordination programming, _ fixed and floating force off modes, as required by TS -3.5 §2.5 / NTCIP entries. The following information shall be all that is required from the user to establish a pattern: 1) Basic NEMA controller timing 2) Cycle length in seconds 3) Desired phase sequence for the particular pattern _- 4) Total seconds of the cycle that a phase is to be active, including green, amber and red clearance times when there is constant demand on all input detectors 5) The coordinated phase or phases (from section 2.7.4.9 below). 6) The offset of the first coordinated phase serviced in the sequence from the reference clock's To in seconds. 6-19 Technical Specolcadons & Description of Pay Items 2.7.3.5 Using the above information in fixed force -off mode, the coordinator must perform the -- following functions for each pattern. 1) Guarantee the coordinated phase(s) programmed time will be serviced in their entirety to achieve coordination between intersections (when not correcting). The programmed time of the first coordinated phase in the phase sequence shall start at To. 2) Calculate each phase's force off point (the point at which a phase's Green must terminate, in order to not violate the following phases' programmed times). 3) Calculate the beginning of each phase's permissive window (the point in the cycle — when the coordinated phase is allowed to yield to each corresponding phase). 4) Calculate the end of each phase's vehicle permissive window (the point proceeding _ a phase's force off point by its minimum time and the prior phase's clearance time). Any phase receiving a vehicle call before the end of vehicle permissive window will be serviced during the current cycle. 5) Calculate the end of each phase's pedestrian permissive window (the point preceding a phase's force off point by pedestrian Walk and pedestrian clearance times and the prior phase's clearance time). Any pedestrian call received by a phase before the end of pedestrian permissive window will be serviced during the current cycle up to the beginning of the phase vehicle green. 6) Guarantee that each phase's programmed time is serviced in full if a call was received before the beginning of permissive window, and the phase does not terminate due to Gap out. 2.7.3.6 Using the same information in floating force -off mode, the coordinator must operate in the same manner as fixed force -off mode, except that if a non - coordinated phase is entered early, it will remain active only for the time programmed in the split time. Automatically setting the max timer in each split to accomplish this function is acceptable. 2.7.3.7 Once the user - selectable data for phase service is entered, the controller unit shall test the plan to insure that the plan does not violate any minimum times based on the _ specified numbers and cycle length. If a faulty plan is detected, the controller unit shall show an error code indicating the problem. If the error is not corrected, the controller unit shall run in free operation mode whenever the erroneous plan is selected. If _ actuated pedestrian movements are programmed, the coordinator shall ignore errors detected due to the pedestrian Walk and clearance times violating the phase split time for any actuated pedestrian. The controller must have a diagnostic screen that lists any of the TS 3.5, §2.5.11 status reasons for free mode operation and must also have a diagnostic status screen. The diagnostic screen shall include all relevant information about the failure that resulted in free mode operation. As an example, if the cycle length does not equal to the sum of the splits, then the indication would be cycle failure and the sum of the splits would be displayed. 6-20 Technical Specifications do Description of Pay Item 2.7.3.8 The coordinator shall be programmable to seek offsets by short -way (lengthening or shortening the cycle lengths). Shorting will have a 0 to 25% entry and lengthening will allow for a 0 to 50% entry. The controller will also contain a dwell method of coordination which will allow the controller to stop at local cycle zero until the offset entry is satisfied. A dwell time entry will also be available which will limit the amount of time the controller stops at local zero. 2.7.3.9 The controller unit coordination program shall be designed to be programmed from the front panel to emulate the operation of a pre -timed controller by recall for applications where no vehicle detection is provided. 2.7.3.10 In additional to the two NTCIP modes of coordination defined in TS -3.5 §2.5, these seven (7) additional modes of coordination are required to be present in the controller: 1) Yield and force -off operation, in which each phase is provided a vehicle and pedestrian yield point and each phase is provided two force -off points. 2) "Easy Coordination' mode, which allows standard NTCIP auto modes, but the Yield points are calculated at a 6% increment for each phase following the coordinated phase. 3) "N.J." mode, which allows a single permissive interval to yield to all phases from the coordinated phase. 4) "Permissive fixed ", which allows three (3) permissive periods to be defined, as well as a force -off for each phase. 5) "Permissive floating ", in which three (3) permissive periods can be defined and a — split time is defined for each phase. The split time defines the maximum time a phase can have during that cycle. 6) "Permissive fixed percent ", where the force -offs are defined as a percent of the — cycle. 7) "Permissive floating percent ", where the split times are defined as a percent of the cycle. 2.7.3.11 For each configuration, a coordinated phase must be selected from Ring 1. A coordinated phase must also be selected from other rings if a compatible phase with the Ring 1 coordinated phase exists. The coordinated phase, or phase pair, shall be selectable from one of the individual phases or phase pairs shown in this table: CONFIGURATION Coordinated 8 Phase Quad 8 Phase 4� Diamond Phase(s) NEMA dual Sequential Sequential ring and 3 Diamond Individual -- 4 or 8 2, 4, 6, or 8 Pairs 2 & 6 or4 2 &6 -- 2 &5,4 &5, &8 1 1 1 1 &6,orl &8 6-21 Technical Sped lcations do Descripdon of Pay !tuns If lead lag operation is selected, then during normal (8) phase operation only one phase -- needs to be selected as the coordinated phase. Compatible phase pairs shall not be forced to begin simultaneously. 2.7.3.12 When establishing its offset from the reference point for external coordination, the coordinator shall reference only the leading edge of the sync pulse, regardless of its width. 2.7.3.13 The internal coordination and upload/download programs shall not interfere with normal intersection operation except when changing ring structure in the controller or active phases. These operations (changing ring structure and active phases) shall require a confirmation and put the controller in a flash condition and a restart sequence. The implementation of revised timing parameters loaded into the timer shall be programmed to occur only at points in the controller coordination cycles which do not alter the controller phase sequence. The controller unit may temporarily drop out of synchronization during the upload/download, but must continue to operate. 2.7.4 Time -Based Coordinator (TBC) 2.7.4.1 The TBC shall allow the features and operations specified in 2.6.7.2 under time of day (T.O.D.) control. 2.7.4.2 The internal reference sync pulse, from which the local offset is calculated, shall resync at midnight, or the resync shall be user programmable with a default to midnight.

The conduit must be continuous, reasonably dry, completely free of debris, and without any sharp projections, edges, or short bends. The conductors shall be installed in such manner and by such methods as to insure against harmful stretching of the conductor or damage to the insulation and shall conform to the recommendations of the cable manufacturer. The Contractor 6-54 Technical Specifications & Description of Pay Items shall furnish, at the request of the Engineer, at least two copies of the manufacturer's recommendations, including methods of attaching pulling tension per conductor size and per radius of conduit bend, and the type of lubricant to be used. _ 11.1.2 All cables in a given conduit run shall be pulled at the same time and the conductors shall be assembled to form one loop in such a manner that the pulling tension is distributed to all the cables. Long, hard pulls will necessitate the use of pulling eyes. For short runs, the cables may be gripped directly by the conductors by forming them into a loop to which the pull wire or rope can be attached. The insulation on each conductor shall be removed before the loop is formed. The method used will depend on the anticipated maximum pulling tension in each case. 11.1.3 In many instances, existing conduits which contain signal cable are to be used for the installation of new cables. In such locations, the existing cable(s) may be used to pull in the new cables. Should the Contractor desire to install new cables without removing the existing cables, the new installation shall be done in such a way as to prevent damage to the existing and/or new cables. In the event of damage, the Contractor shall bear the responsibility of replacement of defective cables. 11.1.4 The manufacturer's recommended maximum pulling tensions shall not be exceeded under any circumstances. If so required by the Engineer, the Contractor shall insert a dynamometer in the pull wire as the cables are being pulled into the conduit to demonstrate that the maximum tensions are not being exceeded. The cable shall be fed freely off the reel into the conduit without making a reverse curve. At the pulling end, the pull wire and or other suitable devices shall be used as required to reduce any hazards to the cable during installation. The cables shall be adequately lubricated to reduce friction and further minimize possible damage. Such lubricants shall not be the grease or oil type used on lead sheathed cables but shall be one of several commercially available wire pulling compounds that are suitable for these kinds of cables. They shall consist of soap, talc, mica, or similar materials and shall be designed to have no deleterious effect on the cables being used. 11.1.5 The cables shall be neatly trained to their destinations in manholes, cabinets, pole bases, pullboxes, and all other terminations. The cable manufacturer's recommended values for the minimum bending radii to which cables may be bent for permanent training during installation shall be adhered to. These limits do not apply to conduit bends, sheaves or other curved surfaces around which these cables may be pulled under tension while being installed. Larger radius bends are required for such conditions. 11.2 Wire and Cable 11.2.1 All wire and cable shall conform to the requirements shown on the plans, except wire and cable specifically covered by other items of this contract.
