<br />GENERAL NOTES
<br />(APPLIES TO ALL SHEETS)
<br />1. THE INFORMATION SHOWN ON THESE DRAWINGS CONCERNING TYPE AND LOCATION OF UNDERGROUND AND OTHER UTILITIES IS NOT GUARANTEED
<br />TO BE ACCURATE OR ALL INCLUSIVE. THE CONTRACTOR IS RESPONSIBLE FOR MAKING HIS OWN DETERMINATIONS AS TO THE TYPE AND
<br />LOCATION OF UNDERGROUND AND OTHER UTILITIES AS MAY BE NECESSARY TO AVOID DAMAGE THERETO. THE CONTRACTORS SHALL NOTIFY THE

<br />2. THE CONTRACTOR SHALL VERIFY LOCATIONS OF ALL EXISTING UTILITIES AND REPORT FINDINGS TO THE LAFARGE PRIOR TO PROCEEDING WITH
<br />RELATED CONSTRUCTION. IT SHALL BE THE CONTRACTORS RESPONSIBILITY TO SATISFY HIMSELF THAT ALL EXISTING UTILITIES, WHETHER
<br />SHOWN ON THESE PLANS OR NOT, HAVE BEEN PROPERLY LOCATED. THE CONTRACTOR SHALL ASSUME FULL RESPONSIBILITY FOR THE PROTECTION

<br />UTILITY COMPANY AND THE COORDINATION OF ALL WORK IN THE PROXIMITY OF THE UTILITIES.
<br />3, IN ADVANCE OF NEW UTILITY CONSTRUCTION, THE CONTRACTOR IS REQUIRED TO POTHOLE ALL UTILITIES TO WHICH THE NEW UTILITIES ARE
<br />TO BE CONNECTED, AND ALL UTILITIES WHICH ARE GOING TO BE CROSSED, ONCE EXPOSED, THE CONTRACTOR SHALL VERIFY THE VERTICAL
<br />AND HORIZONTAL LOCATION OF ALL EXISTING UTILITIES. THE CONTRACTOR SHALL NOTIFY THE LAFARGE OF ANY DIFFERENCES BETWEEN ACTUAL
<br />LOCATIONS AND LOCATIONS GIVEN ON THESE PLANS. NO CONTRACTOR CLAIMS FOR EXTRA COMPENSATION WILL BE GRANTED FOR PROJECT
<br />DELAYS ASSOCIATED WITH REDESIGN NECESSITATED BY CHANGES IN ACTUAL LOCATIONS BASED ON FIELD VERIFICATION. IF THE CONTRACTOR
<br />HAS TO REDO CONSTRUCTION TO AVOID UTILITY CONFLICTS DUE TO HIS FAILURE TO POTHOLE EXISTING STRUCTURES IN ADVANCE OF NEW
<br />UTILITY CONSTRUCTION, NO EXTRA COMPENSATION WALL BE GRANTED.
<br />C THE CONTRACTOR SHALL BE RESPONSIBLE FOR RESTORING ALL SURFACES AND RELATED STRUCTURES SUCH AS DRIVEWAYS, CURBS, GUTTERS,
<br />WALKS, AND BITUMINOUS PAVEMENTS TO ORIGINAL CONDITIONS (OR BETTER) AND GRADES, UNLESS DESIGNATED OTHERWISE ON THE DRAWINGS.
<br />THE LAFARGE OR LAFARGE'S REPRESENTATIVE AND THE CONTRACTOR SHALL TOGETHER COORDINATE THE DOCUMENTATION OF EXISTING GRADES AND
<br />OTHER INFORMATION PRIOR TO ALL CONSTRUCTION ACTIVITIES.
<br />5. THE CONTRACTOR SHALL CONTACT THE UTILITY NOTIFICATION CENTER OF COLORADO (PHONE 1 -500- 922 -1987) FOR THE MARKING OF UNDERGROUND
<br />UTILITIES AT LEAST 48 HOURS PRIOR TO CONSTRUCTION. THE CONTRACTOR SHALL TAKE PRECAUTIONARY MEASURES TO PROTECT ALL UTILITY
<br />LINES SHOWN AND OTHER UTILITY LINES OTHERWISE LOCATED
<br />6. THE LAFARGE- DEVELOPER SHALL PROVIDE THE CONTRACTOR WITH A COMPLETE AND UPDATED SET OF ENGINEERING CONSTRUCTION DRAWINGS.
<br />THESE DRAWINGS, AND ANY REQUIRED PERMITS, SHALL BE AT THE PROJECT SITE AT ALL TIMES. IF NO PLANS APPEAR ON THE PROJECT SITE,
<br />CONSTRUCTION ACTIVITIES MAY BE HALTED AT THE DISCRETION OF THE LAFARGE.
<br />7, BEFORE WORK BEGINS, THE CONTRACTOR SHALL OBTAIN ALL NECESSARY PERMITS AND MUST NOTIFY THE REQUIRED PARTIES AT LEAST 24 HOURS
<br />IN ADVANCE OF COMMENCING CONSTRUCTION ACTIVITIES.
<br />8. THE CONTRACTOR SHALL COMPLY WITH THE PROVISIONS OF THE ATSSA GUIDE FOR WORK AREA TKAFFIC CONTROL AND THE MANUAL OF UNIFORM
<br />TRAFFIC CONTROL DEVICES FOR CONSTRUCTION SIGNAGE.
<br />9. ALL SURPLUS MATERIAL, TOOLS, AND TEMPORARY STRUCTURES, FURNISHED BY THE CONTRACTOR, SHALL BE REMOVED FROM THE PROJECT SITE
<br />BY THE CONTRACTOR. ALL DEBRIS AND RUBBISH CAUSED BY THE OPERATIONS OF THE CONTRACTOR SHALL BE REMOVED, AND THE AREA
<br />OCCUPIED DURING CONSTRUCTION ACTIVITIES SHALL BE RESTORED TO ITS ORIGINAL CONDITION, WITHIN 48 HOURS OF PROJECT COMPLETION.
<br />10. THE CONTRACTOR IS RESPONSIBLE FOR COORDINATION OF INSTALLATION BETWEEN ALL UTILITIES, INCLUDING BUT NOT LIMITED TO WATER
<br />LINES, SPRINKLER LINES. UNDERDRAIN, STORM SEWER, SANITARY SEWER, TELEPHONE, ELECTRIC, SPRINKLER CONTROL WIRING, GAS, FIRE
<br />LINES, AND WATER AND SEWER SERVICE LINES. COORDINATION INCLUDES DETERMINING THE SCHEDULING OF WHICH UTILITIES ARE
<br />INSTALLED WHEN
<br />11. ALL WORK SHALL BE PERFORMED IN ACCORDANCE WITH THE "DESIGN STANDARDS AND CONSTRUCTION SPECIFICATIONS" OF THE COLORADO
<br />DEPARTMENT OF TRANSPORTATION.
<br />12. ALL FILL AREAS AND SUBGRADES SHALL BE BACKFILLED AND COMPACTED TO A MINIMUM OF 95% OF MAXIMUM DENSITY, AS DETERMINED BY ASTM D698.
<br />EXISTING IN PLACE SOILS THAT ARE TO BE USED FOR SUBGRADE SHALL BE SCARIFIED TO A DEPTH OF 6" (INCHES) AND THEN SHALL BE RECOMPACTED
<br />TO THE ABOVE REFERENCED DENSITY. ALL EXISTING VEGETATION AND TOPSOIL MUST BE STRIPPED PRIOR TO SUBGRADE SCARIFICATION AND RECOMPACTION.
<br />13. ALL CONNECTIONS TO THE EXISTING DITCHES SHALL BE DONE IN A WAY SO AS TO MINIMIZE DISRUPTION IN SERVICE TO EXISTING USERS.
<br />14. ALL LENGTHS SHOWN ARE FROM CENTER TO CENTER OF STRUCTURES TO END OF FLARED END SECTIONS.
<br />15. THESE CIVIL DRAWINGS ARE BASED ON THE TOPOGRAPHIC SURVEY BY LAFARGE NORTH AMERICA, DATED OCTOBER 16, 2003. ADDITIONAL SURVEY
<br />INFORMATION IS BASED ON THE TOPOGRAPHIC SURVEY BY SCOTT, COX & ASSOCIATES, INC. DATED MARCH 8, 2004.
<br />16. EXISTING UTILITY AND ELEVATION INFORMATION WAS BASED ON INFORMATION PROVIDED BY LAFARGE NORTH AMERICA, FIELD VERIFICATION IS REQUIRED
<br />FOR ALL EXISTING UTILITIES AND &TIE FEATURES PRIOR TO CONSTRUCTION.
<br />17. CONCRETE USED FOR THE CHANNEL SHALL CONFORM TO THE FOLLOWING SPECIFICATIONS:
<br />A. COMPRESSIVE STRENGTH: MINIMUM 3,500 PSI COMPRESSIVE STRENGTH AT 28 DAYS.
<br />B. SHALL INCORPORATE THE USE OF SYNTHETIC FIBROUS CONCRETE REINFORCEMENT. SEE NOTE 18
<br />C. CEMENT: TYPE I OR II.
<br />D. FINE AGGREGATE: SAND CONFORMING TO ASTM C -33.
<br />E. COARSE AGGREGATE: CRUSHED GRAVEL CONFORMING TO ASTM C -33. MAXIMUM 3/4" SIZE.
<br />F. ENTRAINED AIR: 6% ( +/- 2R).
<br />G. WATER- CEMENT RATIO: 0.45 MAXIMUM.
<br />H. SLUMP: 4" TO 6".
<br />I. CHANNEL SHALL BE FORMED WITH DRESSED LUMBER OR PLYWOOD. THE CONTRACTOR MAY UTILIZE SLIP FORMS PER THE LAFARGE'S APPROVAL.
<br />J. ALL WORK SHALL BE IN ACCORDANCE WITH ACI 301 -89 'SPECIFICATIONS FOR STRUCTURAL CONCRETE FOR BUILDINGS" AND THE COLORADO
<br />DEPARTMENT OF TRANSPORTATION STANDARD SPECIFICATIONS,

<br />19. CONCRETE MIX DESIGN AND FIBROUS REINFORCING SPECIFICATION SHALL BE SUBMITTED TO LAFAR3E FOR REVIEW AND APPROVAL PRIOR TO CONSTRUCTION.
<br />20, CONSTRUCTION OF THE PROPOSED CONCRETE LINED DITCH MAY BE ACCOMPLISHED DURING THE IPRIGATION SEASON (MARCH THROUGH NOVEMBER), AS
<br />LONG AS THE WORK DOES NOT NEGATIVELY AFFECT THE MAINTENANCE AND /OR OPERATIONS OF THE EXISTING SMITH & EMMONS DITCH. ANY WORK
<br />RELATED TO THE EXISTING DITCH, INCLUDING CONNECTIONS TO THE EXISTING DITCH, MOOIFICATIO16 TO THE EXISTING DIVERSION STRUCTURES
<br />AND FILLING OF THE EXISTING DITCH, WALL OCCUR DURING THE NON- IRRIGATION SEASON. THE LArARGE WILL TAKE ALL PRECAUTIONS TO ENSURE
<br />THAT WATER DELIVERY DURING THE IRRIGATION SEASON WILL NOT BE AFFECTED BY THIS WORK.
