Timberline Road & Kechter Road Right Turn Lanes 5 SUMMARY OF WORK PART 1 GENERAL 1.25 Modifications to Time of Completion in the Approved Schedule A. The date of beginning and the time for completion of the work are essential conditions of the Contract Documents and the work embraced shall be commenced on a date specified in the Notice to Proceed. The Contractor will proceed with the work at such rate of progress to ensure full completion within the contract time. It is expressly understood and agreed, by and between the Contractor and the Owner that the contract time for the completion of the work described herein is a reasonable time, taking into consideration the climatic and other factors prevailing in the locality of the work. Every effort shall be made by the Contractor to complete the project within the "Contract Time" shown in the proposal. The "Contract Time" anticipates "Normal" weather and climate conditions in and around the vicinity of the Project site during the times of year that the construction will be carried out. Extensions of time based upon weather conditions shall be granted only if the Contractor demonstrates clearly that such conditions were "unusually severe," would not have been reasonably anticipated, and that such conditions adversely affected the Contractor’s work and thus required additional time to complete the work. The following specifies the procedure for the determination of time extensions for unusually severe weather. The listing below defines the anticipated number of calendar days lost to adverse weather for each month and is based upon National Oceanic and Atmospheric Administration (NOAA) or similar data for the geographic location of the project. Monthly Anticipated Calendar Days Lost to Adverse Weather Conditions JAN FEB MAR APR MAY JUN JUL AUG SEP OCT NOV DEC (7) (4) (4) (4) (6) (3) (4) (2) (3) (3) (2) (5) The above schedule of anticipated adverse weather will constitute the base line for monthly (or portion thereof) weather time evaluations. Upon acknowledgment of the Notice to Proceed and continuing throughout the contract on a monthly basis, actual adverse weather days and the impact of adverse weather days that delay the work will be recorded on a day- to-day basis. It is assumed that the work will be carried out Mondays through Fridays (holidays excepted) unless an approved construction schedule or written authorization from the Owner indicates otherwise. The number of days of delayed work due to adverse weather or the impact thereof will then be compared to the monthly adverse weather schedule above. An actual adverse weather day must prevent work for 50 percent or more of the Contractor’s workday, delay work critical to the timely completion of the project, and be documented by the Contractor. The City Representative observing the construction shall determine on a daily basis whether or not work can proceed or if work is delayed due to adverse weather or the effects thereof. The Contractor shall notify the Engineer in writing of Timberline Road & Kechter Road Right Turn Lanes 6 any disagreement as to whether or not work can proceed on a given date, within 2 calendar days of that date. The Owner will use the above written notification in determining the number of working days for which work was delayed during each month. At the end of each month, if the number of working days for which work was delayed due to adverse weather exceeds that shown in the above schedule, a Change Order will be executed which increases the Contract Time. The number of work days delayed due to adverse weather or the impact thereof will then be converted to Calendar Days based on the contract completion day and date. This conversion assumes a 5-day work week, Mondays through Fridays, holidays excepted; should the Contractor have authorization to work weekends and/or holidays, then the method of conversion of workdays to calendar days would take this into consideration. The contract time period will then be increased by the number of calendar days calculated above and a new contract completion day and date will be set. The Contractor’s schedule must reflect the above-anticipated adverse weather delays on all weather-dependent activities. While extensions of time shall be granted for "unusually severe" weather or climate conditions, the Owner shall make no monetary compensation for any costs to the Contractor arising out of such delays. The Contractor shall comply with the portions of the Contract Documents relating to his project schedule and amendments thereto which result from the "unusually severe" weather condition. Breakdowns in equipment or lack of performance by the Contractor will not be considered justification for an extension of time. Liquidated damages will be assessed as delineated elsewhere. The Contractor shall not be charged with liquidated damages or any excess cost when the delay in completion of the work is due to the following, and the Contractor has promptly given written notice of such delay to the Owner or Engineer. 1. To any preference, priority, or allocation order duly issued by the Owner. 2. To unforeseeable causes beyond the control and without the fault or negligence of the Contractor, including but not restricted to, acts of God, or of the public enemy, acts of the Owner, acts of another Contractor in the performance of a contract with the Owner, fires, floods, epidemics, quarantine restrictions, strikes, freight embargoes, and abnormal and unforeseeable weather as provided above; and 3. To any delays of Subcontractors occasioned by any of the causes specified in paragraphs 1 and 2, above.

Subsection 207.03, paragraph 3 shall include: Per City Code, soil shall be loosened to a depth of not less than eight (8) inches. The Engineer shall be notified if this cannot occur due to existing conditions. Subsection 207.04 is hereby revised to include the following: Topsoil will not be remeasured, but payment shall be based on the quantity identified in the bid tabulation, unless the quantity of Topsoil is significantly changed during construction by an approved Change Order. Bid tabulation quantity is based on final in-place topsoil required to complete the construction. Haul required to redistribute stockpiled topsoil uniformly throughout the project limits shall not be measured and paid for separately, but shall be included in the work. Subsection 207.05 is hereby revised to include the following: The contract unit price for topsoil shall be full compensation for all work necessary to complete the item including removing existing on-site topsoil material, stockpiling the existing topsoil material, haul, redistributing the existing topsoil material onto the re-graded slopes.

Do not cut main lateral tree roots or taproots; cut only smaller roots that interfere with installation of utilities. Cut roots as required for root pruning. Redirect roots in backfill areas where possible. If encountering large, main lateral roots, expose roots beyond excavation limits as required to bend and redirect them without breaking. If encountered immediately adjacent to location of new construction and redirection is not practical, cut roots approximately 3 inches back from new construction and as required for root pruning. Do not allow exposed roots to dry out before placing permanent backfill. Provide temporary earth cover or pack with peat moss and wrap with burlap. Water and maintain in a moist condition. Temporarily support and protect roots from damage until they are permanently relocated and covered with soil. G. ROOT PRUNING Prune roots that are affected by temporary and permanent construction. Prune roots as shown on Drawings and as follows: 1. Cut roots manually by digging a trench and cutting exposed roots with sharp pruning instruments; do not break, tear, chop, or slant the cuts. Do not use a backhoe or other equipment that rips, tears, or pulls roots. 3. Cut Ends: Coat cut ends of roots more than 1-1/2 inches in diameter with an emulsified asphalt or other coating formulated for use on damaged plant tissues and that is acceptable to landscape architect. 4. Temporarily support and protect roots from damage until they are permanently redirected and covered with soil. 5. Cover exposed roots with burlap and water regularly. 6. Backfill as soon as possible according to requirements in Section 200 Earth Work. Root Pruning at Edge of Protection Zone: Prune roots 12 inches outside of the protection zone, by cleanly cutting all roots to the depth of the required excavation. H. CROWN PRUNING Prune branches that are affected by temporary and permanent construction. Prune branches as shown on Drawings and as follows: 1. Pruning Standards: Prune trees according to ANSI A300 (Part 1) Timberline Road & Kechter Road Right Turn Lanes 14 I. REGRADING Lowering Grade: Where new finish grade is indicated below existing grade around trees, slope grade beyond the protection zone. Maintain existing grades within the protection zone. Raising Grade: Where new finish grade is indicated above existing grade around trees, slope grade beyond the protection zone. Maintain existing grades within the protection zone. J. REPAIR AND REPLACEMENT General: Repair or replace trees, shrubs, and other vegetation indicated to remain or be relocated that are damaged by construction operations, in a manner approved by Architect. 1. Submit details of proposed root cutting and tree and shrub repairs. 2. Treat damaged trunks, limbs, and roots according to arborist's written instructions. 3. Perform repairs within 24 hours. 4. Replace vegetation that cannot be repaired and restored to full-growth status, as determined by Landscape Architect. Trees: Remove and replace trees indicated to remain that are more than 25 percent dead or in an unhealthy condition before the end of the corrections period or are damaged during construction operations that Landscape Architect determines are incapable of restoring to normal growth pattern. 1. Provide new trees of same size and species as those being replaced for each tree that measures 6 inches or smaller in caliper size. K. DISPOSAL OF SURPLUS AND WASTE MATERIALS Disposal: Remove excess excavated material, displaced trees, trash and debris, and legally dispose of them off Owner's property.
