DESIGN TEAM

This document is a Conceptual Design Summary which will serve as the starting point for the Basis of De-sign (BOD), a living document that will evolve through the duration of this project. This document was cre-ated starting from the following key elements of developmental discovery:

• Pre-Contract Meeting June 17, 2019

• Kickoff Meeting September 26, 2019

• Investigative Services September 27, 2019

It is not the BOD’s function or intent to document every element of this entire process as it is developed;

rather it is to perform as an organized summary of the key developments of the project process. In addi-tion to the BOD, total documentation of the design process consists of project minutes of meetings, nu-merous design studies and options presented for consideration.

In 2019, Bancroft AE was contracted to provide Architectural/Engineering design services for the St.

Petersburg VA Regional Office in St. Petersburg, FL. The main project focus is the renovation of 10 bathroom suites in building 46. The intent is to provide complete reconfiguration of the existing bathrooms based on the specifications of the bathrooms at building 47. The scope of design services include Schematic Design, Design Development, and Construction Documents.

The optimal solution will update the existing bathrooms to today’s standards including ADA and the VA

Barrier Free Design Standard. In addition, updating finishes and fixtures as the existing finishes are original to the building. The design will also address the issue of backups that occur within the plumbing system during peak times of use.

EXISTING CONDITIONS

In the wake of World War I, on January 5, 1929, Senator Duncan U. Fletcher introduced a bill that would appropriate funds for a Soldiers' Home to be constructed in Florida. Ultimately the bill’s word-ing was changed from "Florida" to "southeastern states," but it did pass and appropriate $2 million for a home.

Within Pinellas County, a campaign immediately began to rally support for construction in the area, namely at the Seminole Point site (although for some time Clearwater was also in the running). Semi-nole Point was chosen as the site on May 26, 1931 - an event which newspapers called the "glorious news" that will "bring Saint Petersburg back." However, only $900,000 in funds was appropriated, due to a decision to use the $2 million also to construct a hospital in Mississippi and an African-

American hospital in Tuskegee, Alabama.

Construction of the first three buildings (what are now buildings 1, 2, and 13), a gatehouse, and em-ployee living quarters (previously on the land given to St. Petersburg Junior College in 1973) were completed in 1933; the hospital by James I. Barnes Company from Indiana, and the living quarters by

J. M. Raymond Construction Company from Jacksonville. The main hospital, under the name

"National Home for Disabled Volunteer Soldiers," and the domiciliary unit opened on March 16, 1933.

Within days seventeen men joined the domiciliary, the first having been Pat Corr of St. Petersburg.

The hospital, however, did not treat its first patient, Charles Boone, the Veterans of Foreign Wars

State Commander from Miami, until March 19, 1933.

Construction continued, as plans were already in place for a Recreation Building (Building 20, com-pleted in 1935), an expanded domiciliary (completed in 1940), and convalescent homes, when the main building opened. Additionally, the VA Regional Office of Florida was moved to Bay Pines, which changed its name from Seminole Point in 1934, from Jacksonville, where they had been located in

1925. Until World War II, construction was non-stop: a 52-bed domiciliary for female veterans opened in 1937 (building 24), a new hospital wing increased bed capacity to 245, and a hydrotherapy treat-ment pavilion on Madeira Beach was constructed in 1934.

World War II brought a surge in patients for which initial construction could not have planned. To in-crease space, the Regional Offices were moved to the Don Ce-Sar, recently vacated by the Army Air

Corps., on Pass-a-Grille Beach and some offices, a brace shop, a chapel, and the library were moved to temporary Quonset-type huts.

But although building space was direly needed, Bay Pines had more than enough land and began to give away portions of the surplus land, beginning with 18 acres in 1955 for the construction of Madei-ra Beach School. Later issuances of land include 359 acres in 1966 to Pinellas County for War Me-morial Park, 60 acres in 1973 to St. Petersburg Junior College, and 17.6 acres in 1974 to the Florida

Department of Transportation.

Meanwhile, in September 1959, funds were approved for a much-needed 140 bed addition to be con-

Executive Summary 1 structed in 1963. Additionally a domiciliary building was converted to add 160 hospital beds, opening by October

8, 1961. The 1963 hospital, however, never surfaced: instead, a new VA Hospital was announced for Gainesville, Florida. Although the issue would resurface many times in the following 15 years, new hospital construction would not be announced again until the late 1970’s.

The next major construction project was the original Nursing Home Care Unit, opened in 1973. Then in 1976, fol-lowing the efforts of Congressman Bill Young and a visit by President Ford, $110 million in appropriations was announced for an addition to the Nursing Home Care Unit, a new domiciliary, the replacement hospital (Building

100) and renovations for Buildings 1 and 22. Prior to those projects, Building 23, the Clinical support Building opened on June 13, 1977.

The Nursing Home Care Unit addition and replacement Domiciliary were completed quickly - bids were accepted starting June 22, 1978 and both were dedicated October 21, 1980. The replacement hospital, however, was not completed until 1983 and dedicated on March 16, 1983. The restoration of Buildings 1 and 22 was not completed until July 1987.

In September 1998 the Regional Office returned to Bay Pines with the completion of a three-story, 125,000 square feet building on-site. Previously the Regional Office had moved from the Don Ce-Sar to a federal building on First Avenue in St. Petersburg in 1967.

Since its original construction in 1933, Bay Pines has continued to expand and adapt to meet the increasing needs of the veterans it serves.

CONSTRUCTION STRATEGIES

Renovating an existing structure while normal activity continues is a challenging task that must be met with advanced planning for phased implementation of the design during construction. The need for a multi-phased construction project becomes evident as clinical and facility operations must continue in existing occupied spaces during construction work without disruptions. During the early planning and design phases a process shall be developed to define the constructability from demolition to completion of construction with a compre-hensive look at the impact of each phase on the new and existing facility. To better anticipate difficulties be-fore plans are finalized and construction commences, project designers and hospital managers must carefully collaborate in developing drawings which document and detail each phase of the project. Several key goals to consider as follows:

1. Construction Phasing

• Project will be required to be phased as necessary to keep facility operational at all times.

• Refer to Phasing plans for outline of phases.

• Coordination with key personnel to develop a detailed phasing plan.

• Phasing to maximize efficiencies and minimize construction impact on the surrounding community.

• Determine construction phase activities that can potentially disrupt existing normal operations.

• Develop mitigation plan to allow operations to continue.

• Study the site and surrounding areas to designate lay-out areas and on-site trailer location.

• Define owner restrictions during construction.

2. Security

• Construction phasing plan to designate areas of construction isolated from secure perimeter of facility.

• Temporary construction fencing to be provided for safety and separation of construction site.

3. Utility Interruptions

• Determine any temporary utilities necessary for facility to remain operational at all times.

• Coordination required with facility management group to schedule any utility interruptions.

• Time and impact of any utility interruptions to be limited.

• Refer to Mechanical, Electrical and Plumbing Narratives contained in this document for additional de-tailed information regarding work related to required interruption of existing engineering systems.
