All other cable buried directly in the L108-6 ZT~h L-108 1-Iv'STAIJ~ATION OF UNDE'3i GROUND CABLE FOR P_ZRPORTS (e) Taped Splices. A taped splice shall be made in the following manner: Bring the cables to their final position and cut so that the conductors will butt. Remove insulation and jacket allowing for bare conductor of proper length to fit compression sleeve cwm ector with 1/4 inch of bare conductor on each side of the connector. Use a sharp knife to pencil insulation and jacket at approximately the same angle as a pencil point. Care must be taken to avoid ni.eking or injuring the conductor during r•etnoval_pf_ insulation ,or penciling. Do not use emery paper on splicing operation since it contains metallic particles. The copper conductors shall be thoroughly cleaned. Join the conductors by inserting them equidistant into the com- pression connection sleeve. Crimp conductors firmly in place with crimping tool that requires a complete crimp before tool can be removed. Test the crimped connection by pulling on the cable. Scrape the insulation to assure that the entire surface over which the tape will be applied"(plus 3 inches on ea eh end) is clean. After scraping wipe the entire area with a clean lint-free c]oth. Do not use solvents. Apply high-voltage rubber tape one-'ralf lapped over bare conductor. This tape should be tensioned as recommended by the manufacturer. Voids in the cormeetor area may be eliminated by highly elongating the tape stretching it just short of its breaking point. Throughout the rest of the splice less tension should be used. Always attempt to exactly half-lap to produce a uniform buildup. Continue buildup to 1 1/2 times cable diameter over the body of the splice with ends tapered a distance of approximately 1 inch over the original jacket. Cover rubber tape with two layers of vinyl pressure-sensitive tape one-half lapped. Do not use glyptol or laceuer over vinyl tape as they react as solvents to the tape. TJO further cable covering. or splice boxes are required. if shielded cable is to be spliced, prepare cable as for a regular taped splice, except that the neoprene jacket shall be removed a distance not less than 5 inches from the beginning of the penciled portion. Carefully unwrap the shielding tape from that portion where jacket has teen removed and cut off so that it extends about 1 inch from end of the jacket. Proceed with the taped splice as described above and tape up to 1/4 inch from the shield on both ends. Build up rubber tare to a thickness equal to the insulation thicker ess or 5/16 inch over connector.

The contractor shall not install slab markers where cable lies in straight lines between obstruction light poles which are spaced 300 feet apart, or less. Cable markers shall be installed immediately above the cable. TSie contractor shall impress the word "CABLE" and directional arrows on each cable marking slab.- The letters shall be approximately Ik inches high and 3 inches wide, with width of stroke 1/2 inch and 1/4 inch deep. The location of each underground cable connection, except at lighting units or insulating transformers, 'shall be ma r'_+,ed by a concrete marker slab placed above the connection. The contractor shall impress the word "SPLICE" on each s]ab. He also shall impress additional circuit identifica- tion symbols on each slab if so desired by the engineer. 108-3.8 SPLICING. Connections of the type shown in the plans shall be made by e~7~erienced persornel regularly engaged in this type of work and shall be made as follows: (a) _Cast Splices.

The following is a recap of the conference held in Y.errville, Texas, on November 20, 1978, for prospective bidders of the Kerrville Airport Improvement construction package. Those items enclosed in parentheses denote comments of clarification from the Engineer or the Owner. 1. Organizations and agencies present: City of Y.errville - John Clanton, Director of Public Works Texas Aeronautics Commission - Bill Schneer, Area Engineer Bovay Engineers, Inc. - John Machado, Project Engineer Cloud Corp. - San Antonio Construction Service Co. - Kerrville Y.elly Construction Co. - San Antonia Olmos Construction Co. - Austin Olmos Equipment Co. - San Antonio O.E. Schwartz Construction Co. - Kerrville Waggoner Construction - Austin 2. Proceedings -- Mr. Machado introduced himself as representative of the ENGINEER, Mr. Clanton as representative of the OWNER, and Mr. Schneer as representative of the Texas Aeronautics Commission, who will act as an official construction observer. -- Mr. Machado asked the BIDDERS if there were any questions regarding the plans or specifications. No response. -- Mr. Machado said that bids would be accepted for a lump sum price based on unit cost prices, with the lowest responsive bidder of the base bid and any combination of alternates being selected by the OWNER for this construction. Payment for work will be based on quantities of work and material accomplished, based on unit costs listed in the Bidding Schedule, P-5 to P-8 of the Contract Documents. (The BIDDERS should carefully read Measurement and Payment items of each section of the Technical Specifications. Payment shall be made only for those items shown on the Bidding Schedule; other costs will be considered incidental to construction and should be accounted for within the unit costs.) -- Mr. Machado said that 120 working days will be allowed for construction, unless a compromise schedule would be required by the BIDDERS to complete the project on time. There was no response; therefore 120 working days will becane the construction time limit for page SF-} of the Contract Documents. Minutes -- Kerrville Airport Nov. 21, 1978 -- A question was raised regarding surveying. Mr. Machado said all surveying will be the responsibility of and paid for by the Contractor. -- Mr. Machado briefly went through the drawings with the BIDDERS. A question was raised regarding water sources. Mr. Clanton said a hydrant is available for Contractor use, but water will not be paid for by the OWNER. 4Jater will be purchased by the Contractor at the rate of $1.00/1000 gallons. -- Mr. Machado mentioned that in all cases where 4" asphalt surface is shown, the BIDDERS will only consider 2" for this construction. Another 2" will be placed in the future under a separate contract. -- Regarding clearing and grubbing, Mr. Clanton said that there are no underground utilities or power lines in the area of construction; this should simplify operations. Regarding wasting and spoil, Mr. Clanton said an abandoned gravel pit at the north end of RW 2/20 will be available for stripped and wasted materials. -- A question was raised regarding striping of the taxiway and Note 3 on Drawing 7; striping must be minimum 6" wide, not thick, as indicated. -- A question was raised regarding the seal coat for the apron, whether or not aggregate is required or optional. The BIDDERS will include a unit cost and carry-out for both emulsion and aggregate. (The aggregate provides a rougher textured seal coat and is therefore more skid resistant. Emulsion and aggregate will be required for aircraft safety.) -- A question was raised regarding final elevations, whether the elevations were for the final 4" asphalt surface or proposed 2" surface under this contract. Mr. Machado said that the elevations are set for the 2" surface and that a 2" overlay will be placed over all runways, taxiways and apron area at some time in the future. -- A question was raised regarding the Contractors provision of a desk and telephone for the ENGINEER; the Contractor will not be required to provide a desk or telephone. -- A question was raised regarding insurance amounts of $1 million/accident, $2.5 million/occurance. This amount remains as shown. -- The conference was moved to the actual airport site for observation. There were no further comments, and the conference was adjourned on the site. 3. (The BIDDERS are cautioned that modifications to the Technical Specifi- cations are contained in section SP20 of the Contract Documents, and should be read over carefully prior to bidding.)
