GOVERNING STANDARDS: ALL WORK SHALL CONFORM TO THE LATEST EDITIONS OF THE HARRIS COUNTY ENGINEERING DEPARTMENT'S STANDARD SPECIFICATIONS FOR CONSTRUCTION OF HIGHWAYS, STREETS, AND BRIDGES, THE CITY OF HOUSTON'S STANDARD SPECIFICATIONS FOR PUBLIC WORKS CONSTRUCTION (IF APPLICABLE), AND ALL APPLICABLE LOCAL, STATE, AND FEDERAL REGULATIONS. IN CASE OF CONFLICT, THE MOST STRINGENT REQUIREMENTS SHALL GOVERN. B. THE DRILLED SHAFT FOR SOLAR LIGHT POLES WERE DESIGNED FOR A BASIC WIND SPEED OF 134 MPH. THE MAXIMUM HEIGHT OF THE POLE WAS CONSIDERED TO BE 30 FEET HAVING A MAXIMUM LENGHT OF MAST ARM OF 8 FEET. C. THE SOIL TYPE AT THE PROJECT SITE WAS ASSUMED TO BE BASICALLY A MEDIUM TO LOW PLASTIC CLAY TYPE WITH A MINIMUM VALUE OF TEXAS CONE PENETRATION (TCP) NUMBER OF 10. CONTRACTORS OR OTHER STOCKHOLDERS SHALL CAREFULLY REVIEW THE SUBSURFACE CONDITIONS ENSURING THIS MINIMUM CRITERIA TO BE MET AT THE PROJECT SITE. ANY VARIATIONS ENCOUNTERED DURING CONSTRUCTION THAT DIFFER FROM THIS ASSUMED SOIL CONDITION SHALL BE IMMEDIATELY BROUGHT TO THE ATTENTION OF THE ENGINEER. D. THE CONTRACTOR IS RESPONSIBLE FOR OBTAINING ALL NECESSARY PERMITS AND APPROVALS FROM HARRIS COUNTY AND ANY OTHER RELEVANT AUTHORITIES PRIOR TO COMMENCING WORK. E. THE LOCATION AND DIMENSIONS OF THE DRILLED SHAFT SHALL BE AS SHOWN ON THE PLANS. ANY FIELD ADJUSTMENTS MUST BE APPROVED IN WRITING BY THE ENGINEER. VERIFY ALL DIMENSIONS AND ELEVATIONS PRIOR TO DRILLING. F. DRILLING SHALL BE PERFORMED USING EQUIPMENT AND METHODS THAT WILL MINIMIZE DISTURBANCE TO THE SURROUNDING SOIL. THE CONTRACTOR SHALL TAKE NECESSARY PRECAUTIONS TO PREVENT CAVING, SLOUGHING, AND NECKING OF THE SHAFT. G. TEMPORARY CASING MAY BE REQUIRED DEPENDING ON SUBSURFACE CONDITIONS. IF USED, THE CASING SHALL BE INSTALLED AND REMOVED IN A MANNER THAT DOES NOT DISTURB THE SURROUNDING SOIL OR THE CONCRETE PLACEMENT. THE CONTRACTOR SHALL SUBMIT A DETAILED PLAN FOR CASING INSTALLATION AND REMOVAL FOR THE ENGINEER'S APPROVAL. H. CONCRETE SHALL BE PLACED IN A CONTINUOUS OPERATION FROM THE BOTTOM OF THE SHAFT TO THE TOP. CONCRETE SHALL BE PLACED USING A TREMIE PIPE OR OTHER APPROVED METHOD TO PREVENT SEGREGATION AND ENSURE PROPER CONSOLIDATION. FREE-FALL PLACEMENT WILL NOT BE PERMITTED UNLESS SPECIFICALLY APPROVED BY THE ENGINEER FOR DRY, STABLE HOLES. I. CONCRETE MIX DESIGN: CONCRETE SHALL CONFORM TO THE REQUIREMENTS SPECIFIED IN ITEM 416 OF THE HARRIS COUNTY ENGINEERING DISTRICT'S STANDARD SPECIFICATIONS. THE MINIMUM COMPRESSIVE STRENGTH AT 28 DAYS SHALL BE 4000 PSI. J. REINFORCING STEEL SHALL CONFORM TO ASTM A615, GRADE 60, UNLESS OTHERWISE SPECIFIED. REINFORCEMENT SHALL BE INSTALLED AS SHOWN ON THE PLANS AND SECURELY TIED TO MAINTAIN PROPER POSITION DURING CONCRETE PLACEMENT. MINIMUM CONCRETE COVER SHALL BE MAINTAINED AS SPECIFIED ON THE PLANS. K. ANCHOR BOLTS FOR THE LIGHT POLE SHALL BE SET ACCURATELY AND SECURELY IN ACCORDANCE WITH THE LIGHT POLE MANUFACTURER'S RECOMMENDATIONS AND AS DETAILED ON THE PLANS. A TEMPLATE SHALL BE USED TO ENSURE PROPER BOLT ALIGNMENT AND SPACING. THE TOP PROJECTION OF THE ANCHOR BOLTS SHALL BE AS SPECIFIED ON THE PLANS. L. THE ENGINEER OR THEIR REPRESENTATIVE SHALL BE PRESENT DURING DRILLING, REINFORCEMENT PLACEMENT, AND CONCRETE PLACEMENT. THE CONTRACTOR SHALL NOTIFY THE ENGINEER AT LEAST 24 HOURS PRIOR TO EACH OF THESE CRITICAL OPERATIONS. M. THE CONTRACTOR SHALL BE SOLELY RESPONSIBLE FOR MAINTAINING A SAFE WORK ENVIRONMENT IN ACCORDANCE WITH ALL APPLICABLE SAFETY REGULATIONS. N. UPON COMPLETION OF THE WORK, THE CONTRACTOR SHALL REMOVE ALL DEBRIS AND RESTORE THE SITE TO ITS ORIGINAL OR BETTER CONDITION. O. ALL DIMENSIONS RELATING TO REINFORCING STEEL ARE TO CENTERS OF BARS.
