Mr. ANDREWS. We will turn over to expansion of facilities, Capito Power Plant.
On page 92 of the bill there is a new item of $250,000 for furthe expansion work at the Capitol Power Plant, which I guess isn't really a powerplant any more.
Will you tell us about this request !
Mr. HENLOCK. Public Law 85–895, 85th Congress, approved Ser tember 2, 1958, authorized and directed the Architect of the Capita under the direction of the House Office Building Commission, to effei changes, improvements, and expansion in the facilities of the Capiti Power Plant and its steam and chilled water distribution system necessary to provide steam and chilled water for the Rayburn Hou Office Building, and for other improvements and projects then unde way or proposed, and authorized the appropriation of a total amou of $6,500,000 for such purpose.
At that time, six new construction projects were contemplated or in progress: The Rayburn House Office Building, the cafeteria in the courtyard of the Longworth House Office Building, the garage in the courtyard of the Cannon House Office Building, the new Senate subway transportation system, the House subway transportation system, and extension of the east-central front of the Capitol and other changes and improvements authorized under the Extension of the Capitol project. There was also contemplated replacement of the 60-year-old heating system in the main library of Congress Building with a new heating and air-conditioning system. Most of these improvements have Dow been completed.
In effecting the changes, improvements, and expansion in the Capitol Power Plant and its steam and chilled water distribution systems, it has been necessary to gear the same to the timetable under which the new projects have been accomplished. The Capitol Power Plant program has been geared accordingly and 85 percent of the work authorized by Public Law 85–895 has now been completed or placed under contract. As of March 1, 1967, the total obligated under Public Law 85–895
$5,161,412. It is estimated that during the period March 1, 1967– June 30, 1968, it will be necessary to obligate an additional $1,255,588, or a total obligation of $6,417,000. As of March 1, 1967, a total of 4.566,493 has been disbursed. During the period March 1, 1967-June
1. 1968, it is estimated it will be necessary to disburse an additional $1,433,507, or a total of $6 million. As the total appropriated to date umounts to $5,750,000, it is necessary to request an appropriation of $250,000 for the fiscal year 1968 in order to have available sufficient finds to liquidate obligations.
We have prepared detailed tables of obligations and expenses if you
Mr. HENLOCK. We show in our financial statement, that, to date, for boiler plant expansion, we have actually obligated $1,719,664; for refrigeration plant expansion, $1,785,022; for distribution system expansion, $743,170. The main obligations to be incurred in 1968 is $813,121 to complete the expansion of the distribution systems, and $255,000 to complete the auxiliary equipment, pipe and electrical work under the boiler plant expansion program.
IMPROVEMENTS AND CHANGES TO DATE On pages 145–148 there is a detailed account of everything that has been done under the project to date, showing what expansions have been effected and how such expansions have increased the capacity of the plant. I can read it or just insert it in the record, as you wish.
Mr. ANDREWS. We can just insert it in the record there. (The pages follow :) Improvements and changes effected, to date, have included the following: Two 1100-ton refrigeration machines, complete with geared drives and 1250 horsepower electric motors, and two 2200-ton refrigeration machines, complete with geared drives and 2500 horsepower electric motors, have been installed at the Capitol Power Plant's refrigeration plant. Installation of these four machines has increased the capacity of the refrigeration plant from a total of 8,800 tons to 15,400 tons.
As an adjunct to these installations, a 3-cell cooling tower having a capacity equivalent to the condensing requirements of three 2200-ton refrigeration machines was constructed on the Capitol Power Plant grounds.
An additional chilled water pump of 9800 gallons per minute capacity, having hydraulic characteristics identical with those of three existing chilled water pumps, was installed at the plant. The four pumps now have a total pumping capacity of 39,200 gallons per minute at an imposed head of 245 feet of water.
A dual piping system, consisting of one chilled water supply main and one return main, was installed from the southeast corner of the Old Senate Office Building to the Senate Terrace of the Capitol Building. This new section of chilled water piping established a physical connection between previously separate east and west distribution systems, thus providing a complete loop circuit from and to the Capitol Power Plant. This loop circuit has made possible a sucCessful redistribution of the chilled water supply to all buildings connected to the system-a compelling requirement brought about by the construction of the Rayburn House Office Building.
A new railroad siding has been constructed on the Virginia Avenue side of the Capitol Power Plant Grounds. The new track system is designed to accommodate storage for eight 70-ton coal cars, while 8 additional cars of like capacity can be delivered to or removed from the plant grounds. This new siding has substantially expedited the coal-handling process and has eliminated the frequent car derailments and other hazards experienced with the old track system.
Four oil-fire steam generators, each having a capacity to produce 50,000 pounds of steam every hour, were installed at the plant. The addition of these oil-fired steam generators has increased the installed steam generating capacity of the Capítol Power Plant from 330,000 pounds per hour to 530,000 pounds per hour.
Oil storage facilities, installed at the plant, include two 10,000-gallon underground steel tanks connected by a concrete tunnel to an underground concrete storage tank with sufficient capacity to store 200,000 gallons of fuel oil.
The antiquated coal-handling system, placed in operation in 1910 and designed to alternately deliver coal from the storage yard or track hopper to the coal bonkers within the plant, was removed from service in the spring of 1965 ; was demolished, and replaced by a modern system of hoppers, inclined belt conveyors, oil-fired car-thawing devices and a mechanical car shaker. The new system is capable of delivering variable quantities of coal up to approximately 200 tons maximum each hour from either a track hopper where coal is dumped from the cars, or from a coal-yard hopper in the storage yard; so that coal can now be conveyed from the track hopper to the bunkers, from the track hopper to the storage yard, or from the storage yard to the bunkers through separate systems of inclined conveyor belts.
A contract was awarded in the fall of 1966 for accomplishing modifications and extensions to the portion of the west steam distribution system located under
South Capitol Street, extending from Canal Street to Independence Avenue. Work under this contract is now in progress.
A contract was awarded in March, 1967, for the manufacture and delivery of a new water treatment plant, to be installed in the east side of the north boiler room under a contract yet to be awarded. Completion of this installation is scheduled for January, 1968.
In addition to the contract for installation of the new water treatment plant, the principal improvements yet to be contracted are the modifications and extensions to the existing steam distribution systems authorized by Public Law 85–895, including new steam service facilities and connections to the Capitol Building, via the west front grounds, and modifications to the piping systems serving the Government Printing Office and the City Post Office; also, replacement of the deteriorated cork insulation on the 24-inch pipes in the chilled water tunnel under South Capitol Street, and rehabilitation of the structural steel frames supporting the pipes in this tunnel.
Mr. ANDREWS. Will this $250,000 wind up this improvement ?
Mr. HENLOCK. No, sir, we will still need the balance of the authorization, $500,000, to complete the project and meet all the obligations we show projected on the sheets we just gave you.
Mr. ANDREWS. Public Law 85–895, 85th Congress, approved September 2, 1958. That is the law you operate under?
Mr. HENLOCK. Yes, sir, and we have had to gear the expansion program to the timetable under which each of the new projects has been accomplished.
Mr. *ANDREWS. That authorization was for $6,500,000.
Mr. ANDREWS. As against the $6,500,000, how much has been appropriated?
Mr. HENLOCK. $5,750,000.
Mr. ANDREWS. And this $250,000 would be the remaining approprition request.
Mr. HENLOCK. The $250,000 will bring the appropriation up to $6 million and will then leave $500,000 more to be appropriated to liquidate final obligations in the fiscal year 1969.
Mr. ANDREWS. Do you say how much has been appropriated as against that?
Mr. HENLOCK. $5,750,000.
Mr. HENLOCK. $750,000. $750,000 is the unappropriated contract authority right at the present time. If you give us the $250,000, it will leave for the fiscal year 1969 $500,000 necessary to complete liquidating the contract authority.
Mr. ANDREWS. As of June 30, 1968, you would have an outstanding total obligation of $6,417,000 ?
Mr. HENLOCK. Our obligations are expected to total $6,417,000 by June 30, 1968, and by that date we expect to have liquidated $6 million of those obligations.
Mr. ANDREWS. All except $417,000 ?
Mr. ANDREWS. Would you seek that appropriation in the 1969 fiscal year budget ?
Mr. HENLOCK. Yes, sir. In fact, we would actually seek the full $500,000. There would be an additional obligation of $83,000 for inspection and supervision of the work in the final year.
Mr. ANDREWS. In other words, that would get all that you were authorized under Public Law 85–895–
