Cyclical Maintenance

Renovation to Publication Distribution Service, Longworth Building..

The Publication Distribution Service Division of The Doorkeeper has
recently upgraded and expanded its capabilities which included the
installation of new equipment. Extensive modifications to the
facilities are required to adequately accommodate this equipment and
provide a satisfactory work environment for Publications Distribution
Service employees. Due to the broad scope of the changes in the
Division's function, work is required in most of the areas assigned to
the Division.

..$ 437,000

These funds are requested to perform these renovations. The work
will be performed by skilled temporary personnel supervised by in-house
staff. The requested funds have been adjusted from previous requests
to account for preliminary work which has been completed by in-house
forces with maintenance funds. This request also includes funds for
areas added to the scope since the original request. This project was
requested and denied in fiscal years 1993 and 1994. Approval to
request funds in the fiscal year 1995 budget for this project has been
sought from the House Office Building Commission.

Structural Study, Cannon Building Garage Floors.

The Cannon Building garage floor slab is deteriorating due to the
water and salts which are deposited on the slab by automobiles.
Concrete pan construction, and its structural integrity, are
dramatically affected by this type of deterioration. There is already
visible evidence. Small hairline cracks have allowed water-borne
chlorides to penetrate the deck and attack the reinforcing bars.

force to cause the concrete to spall and delaminate. This destructive
action, if allowed to continue, could lead to severe structural damage.

Expansion Joint Replacement, Rayburn Building (continued)

This condition exists in the center and west courtyards of the
Rayburn House Office Building. In fiscal year 1992, $150,000 was
appropriated which allowed the repair of the east courtyard. With this
request the west courtyard will be waterproofed in fiscal year 1995.
The funds will be left in the budget base for fiscal year 1996 to
accommodate the repairs in the center courtyard. Approval to request
funds in the fiscal year 1995 budget for this project has been sought
from the House Office Building Commission. This project was requested
and denied in fiscal year 1994.

Modernization of Longworth Toilets and Anterooms.

$ 299,000

In response to a long standing need to maximize the efficient use of existing space within the House Office Buildings, a proposal was developed to convert certain toilet area anterooms to office space

The men's and women's restrooms on the north end of floors four through seven of the Longworth House office Buildings can

be
reconfigured to provide additional office space. These anterooms were
originally built to provide passageway and lounge areas for the toilet
rooms. Present day use patterns indicate that these areas are not
utilized at all, and thus the space is available for other, higher
priority, uses such as conversion to office space. When the conversion
is completed, approximately 300 square feet of usable office space will
be achieved on each floor. At the same time, four sets of the
restrooms will be renovated to comply with the recent ADA accessibility
standards. Approval to request funds in the fiscal year 1995 budget for
this project has been sought from the House Office Building Commission.
This project was requested and denied in fiscal year 1994.

Four of the six escalators between the Rayburn and the Longworth Buildings have been modernized. The two remaining escalators were requested to be modernized with reprogrammed funds during fiscal year 1994 due to serious safety concerns. If the reprogramming is not approved, full funding for their replacement is included in this request. The balance of the escalators in the Rayburn Building, twenty three in all, should have their safety features and controls updated. Several of these escalators have suffered a high level of wear and could become hazardous if the situation is ignored. These escalators receive a high level of maintenance but their continued degradation requires attention.

of

Escalator technology has advanced dramatically in the area safety and motion sensor and controls since 1958. Escalators have recently been the focus of many litigations involving personal injury and death. The primary factors in most of these incidents were age of the equipment and lack of modern safety sensors.

This request is to support the continued implementation of a phased modernization and improvement program. As stated before, if the two remaining escalators between the Rayburn and Longworth Buildings cannot be replaced with reprogrammed funds, then they will be replaced with funds in this request. The balance would then be used to upgrade five of the remaining 23 escalators in the Rayburn Building. Should

Escalator Modernization, Longworth and Rayburn Buildings.

The House Office Buildings have thirty-one escalators all of which
have been in service since occupancy of the Rayburn Building beginning
in 1964. Since this equipment's installation there have been many
industry safety and design improvements. Some changes have been made
but substantial control and equipment modification are still required.
