- Description
- This is a combined synopsis/solicitation for commercial items prepared in accordance with the format in Subpart 12.6, as supplemented with additional information included in this notice. THIS ANNOUNCEMENT CONSTITUTES THE ONLY SOLICITATION; QUOTATIONS ARE BEING REQUESTED AND A WRITTEN SOLICITATION WILL NOT BE ISSUED. This Request for Quotation (DTCG87-04-Q-643015) incorporates provisions and clauses in effect through Federal Acquisition Circular 2001-14 and is issued as a 100 percent small business set-aside. The contract will be awarded using simplified acquisition procedures in accordance with FAR Part 13.5. The procurement will be awarded as a firm-fixed-price contract. The intent of this project is to replace a damaged guy insulator 5-A-twr#3-2 and mount an FM antenna system on Tower #4 at LORSTA Tok. This sectionalized LORAN-C SLT antenna system consists of four identical cable panels supported by four 700-foot towers. The antenna wire array is directly energized by the Loran-C transmitter. Large voltage differences exist between array and ground or metallic devices within the electromagnetic (EM) field. Support towers, backstays, and electrical guys are insulated from the direct Loran-C transmitter voltage by the corner point insulators, but they nevertheless are at some voltage level above that of ground because of the EM field, and triboelectric effects caused by wind, snow, etc. Each galvanized steel tower has a 7-foot face width and is supported by three lanes of nine insulated guys. The insulator that needs to be replaced is on Guy Level 5, Lane A, second insulator from the top. The FM antenna system consists of (2) ERI 1105-2a antennas with radomes. The pair of antennas will be connected with a dipole approximately 10? in length. The antenna system shall be mounted between 170? and 140?. Maintenance Items: Rig a temporary structural guy and replace insulator on Tower #3, Guy Level 5, Lane A, second insulator from the top. Install FM antenna system on Tower # 4. Complete a written report summarizing all of the work. All inspections, adjustments to tower alignments and guy tensions shall be performed by a Registered Professional Civil or Structural Engineer or by a Professional meeting the following criteria: Minimum of five years experience erecting or inspecting towers and minimum of two years experience working on guyed towers of 500 feet or greater and minimum of two years as a supervisor of tower inspection and maintenance work and experience in measuring and correcting tower alignment, guy tensions, and twist. Reports shall be performed by a Registered Professional Civil or Structural Engineer. The same registered engineer shall be available to provide technical guidance to personnel performing the tower inspection, alignments and tensions. The contractor shall comply with all Coast Guard safety standards as described in COMDTINST M11000.4A, U.S. Coast Guard Tower Manual, 2002. Weather history at Tanacross as follows: Mean Daily Max/Min Temperature (October): 36?F/21?F. Mean Daily Max/Min Temperature (November): 10?F/-4?F. Work aloft shall not be carried out when the ground wind exceeds 20 mph, electrical storm activity is present, or fog obscures clear visibility between the ground and the top of the tower. A written notice of acceptance issued by the Contracting Officer will establish the completion of this contract. The COR will conduct a final inspection when the Contractor is finished with project work and will determine if all work satisfies the contract requirements. Discrepancies or omissions, if found, will be noted. Comply with all applicable federal, state and local laws and regulations concerning environmental pollution prevention, control, and abatement. Comply with all applicable provisions of the Corps of Engineers Manual, EM 385-1-1, entitled ?General Safety Requirements?, which are in effect on the date of solicitation. Quarters and Messing will not be provided. Any existing materials which are removed and not reused shall be retained on-site at a location designated by the COR. Scrap materials and debris shall be disposed of in a designated disposal area or removed from Government property, all at the Contractor?s expense. TEMPORARY SERVICES AND UTILITIES: Coordinate the use of temporary services and utilities with the COR. Potable Water and Electrical Power will be provided by the Coast Guard. The contractor shall provide all other temporary services, utilities, and equipment required to complete the work. The Contractor shall be fully responsible for the security of all stored material and equipment, and shall provide any security measures he deems necessary, at his expense. Prior to the commencement of work, submit to the COR a complete list of all employees, representatives, and subcontractors, including name, age, and address. MAINTENANCE: Measure initial alignment of Tower #3. Rig temporary structural guy at 5-A-twr#3 and tension appropriately. Replace insulator on Tower #3, lane A, guy level 5, second from the top. Adjust guy wire to appropriate tension and measure alignment. Mount an FM antenna system consisting of (2) ERI 1105-2a antennas with radomes on Tower #4, leg A. REPORT: Complete a written report summarizing all of the work and the alignment data. SUBMITTAL: Execution plan for replacing insulator. Rigging: Supply all materials, including temporary guy, blocks, harnesses and safety devices, and all other devices required for rigging. Haul Vehicle: Supply haul vehicle for evolution as needed. Camera Equipment: Supply cameras and all film needed to fulfill photo requirements. High-Powered Telescopic Viewing Equipment: Supply a Questar telescope or equivalent to inspect guy and insulators. Transit: Supply a transit to measure alignment. Transit must be calibrated within six months of project work. Submit a copy of the calibration certificate. Communications: Provide reliable radio communications. Continuous contact between the ground and inspection crew is required. Tensioning Equipment: Supply tensioning equipment. Dynamometer must be calibrated within six months of project work. Dynamometer may have a maximum reading capability of 15000 lbs with incremental measurements of not more than 100 lbs. TENSIONS AND ALIGNMENT: Tensions: Measure initial guy tension of 5-A-twr#3. Following tower maintenance set tension to appropriate level and record final tension according to below. Alignment: Measure and record tower alignment by the ?one leg? method. Following tower maintenance align the tower as necessary using tension adjustments described herein. If the alignment is within parameters it is not necessary to measure and record tensions on the entire tower. If the alignment of tower #3 is not within parameters, measure all tensions and adjust accordingly to bring tower alignment within parameters. GUY TENSIONS: Procedures: Measure and record initial guy tension. Guy tensions shall be measured using a dynamometer, hand winch and guy grip. Adjust the tension so that guy tension, alignment, turnbuckles, and twist are all set to design levels. If after final adjustment the turnbuckle does not afford at least 1.0 inch of adjustment, it shall be repositioned with a new PLP dead end guy-grip. Tolerances: No tensions outside of design tolerances will be permitted. Design tolerances are ?5% to +15% of the values in the Guy Tensions Temperature Correction Chart. Conditions: Gradual Corrections Required: If realignment is necessary, no guy level shall be pulled more than two inches out of alignment as compared with the guy levels immediately above and below the level being realigned. Wind: Ground wind speed must be less than 10 knots during tension measurements. ALIGNMENT MEASUREMENTS AND PLOTS: Three transit positions must be used. With respect to the tower, the positions are 60 degrees apart. (60 degrees between P1 and P2; 60 degrees between P2 and P3). Care must be taken to take readings on the correct leg at each position. After leveling the transit, sight the edge or center of the leg near the base of the tower and lock the horizontal motion. Estimate deflections at each guy level. (Leg diameters are listed on the alignment readings data sheet in Appendix B.) Invert scope and repeat. Average the readings. Repeat for each leg. Record and plot the readings. Ground wind speed must be less than 10 knots during alignment. Each set of averaged readings at a guy level shall be plotted to fix the position of the tower relative to true vertical. The fix is formed by the position lines of the three legs. Under ideal conditions, the plotted fix should be a point. If the fix instead results in a triangle and the triangle is plotted larger than 1? inches at plot scale in its greatest dimension, that particular level of shots shall be repeated and re-plotted. The distance from true vertical (zero along each axis) to the tower?s actual location (plotted) shall be calculated for each level and compared to the acceptable tolerances. After the tower is aligned and guys are tensioned correctly, final alignment readings shall be taken and recorded. The plot and all data shall be included with the final report. REPLACE GUY INSULATOR (5-A-twr#3-2): Following the measurement of initial tension of 5-A-twr#3 and alignment of tower #3, rig temporary guy and replace damaged insulator in accordance with the approved procedures. The procedures shall be stamped by a registered professional engineer and approved by the Coast Guard. The broken insulator is on Tower #3, Guy Level 5, Lane A, second from the top. It is located approximately 50? down the guy wire from the guy takeoff point. The Coast Guard will provide the replacement insulator and guy grip. Adjust guy wire to appropriate tension. Record the final tension and alignment data. If tower is not within alignment parameters, make the necessary adjustments to bring within tolerance. INSTALL FM ANTENNA: The FM antenna system consists of (2) ERI 1105-2a antennas with radomes. The pair of antennas will be connected with a dipole approximately 10? in length. The antenna system shall be mounted between 170? and 140? on leg A. The Coast Guard will furnish the antennas, radomes, and miscellaneous connecting hardware. Establish signal to the antenna system by installing ?? heliax cable from the junction at ground level to the base of the antenna. Connect ?? heliax to the antenna via the furnished flange. Ground the antenna system to the tower. The Coast Guard will provide the cable, tape, grounding hardware, and any miscellaneous materials needed to affix the cable to the tower. Replace the u-bolts on an identical antenna system mounted on leg C of the same tower between 170? and 140?. The Coast Guard will provide the u-bolts. Submit three (3) copies of the final report to the Contracting Officer within 15 working days after completing work at the site. Also submit one CD-Rom containing the report. All pages shall be bound in loose-leaf binders. All data and plots for alignment of tower #3 shall be submitted. Tension readings shall be recorded as necessary in lbs. after adjustments are made. All data shall include date, weather conditions, and instrument type. Include a summary of all work completed. Upon completion of the required maintenance all rigging shall be removed from the tower.
