U.S. DEPARTMENT OF TRANSPORTATION

MARITIME ADMINISTRATION

BACKGROUND

The United States Merchant Martine Academy (USMMA) is an agency of the Maritime Administration (MARAD) managed by the United States Department of Transportation.

The USMMA is listed on the National Register of Historic Places. Therefore, all work shall be consistent with the Secretary of the Interior's Standards for the Treatment of Historic Properties (36 CFR part 68) http://www.nps.gov/tps/standards/four-treatments/treatment-guidelines.pdf.

All work shall meet or exceed the standards provided in the Secretary of the Interior’s Standards for Rehabilitation and guidelines for applying the standards published by the National Park Service, U.S. Department of the Interior 36 CFR 67.7 - Standards for rehabilitation.

OBJECTIVE

The USMMA seeks the restoration of the Academy greenhouse.

SCOPE

The USMMA is looking for a qualified, licensed and insured contractor to provide labor, material, transportation, tools, equipment and supervision to restore the Academy greenhouse.

The greenhouse consists of two (2) William H. Lutton structures joined together with the use of a valley. The main house is divided into three (3) 8’3”bays with four (4)- 24-3/4” centerline sections. The structure is approximately 25 in length and approximately is approximately 9’ 6- 1/2” tall. It has two (2) gable ends with a door at each gable. The greenhouse has both roof and side sashes which are all manually operated. The main room has canopy over front door but not over the back door. The smaller greenhouse structure is approximately 12 X 12’ with an egress door and canopy. Outside of the greenhouse there are several cold frames.

The selected contractor will be responsible for the following tasks:

Greenhouse

1. The paint on the greenhouse and surrounding masonry contains lead. The Contractor shall hire a certified lead abatement company to remove the loose paint chips and encapsulate all surfaced that contain lead. Note that this work must be performed by hand since power-washing is not acceptable.

2. The Contractor shall examine the brickwork on the inside and outside of the greenhouse and replace all broken bricks and reset all loose bricks. All masonry work will be brought up to original condition.

3. All outside brick work will be painted using a high grade exterior paint.

4. All glazing substrates are to be removed and discarded. Care must be given to gingerly remove all nails (mostly galvanized cut nails) and all bedding to reveal cypress. After removing all caulk, wire brushing is required to finely remove excess. All wood that cannot be restored must be replaced with red gulf clear heart cypress. All fastening screws should be stainless steel, 1/8” Phillips-head screws by 5/8” or ¾” depending on locations

5. All wood sashes on both roof and sides are to be inspected and either repaired or replaced in kind. Generally speaking, the roof has the greatest amount of degradation. If sashes are removed to be milled, take note that all intermediate muntins that divide the sections require mortise and tenon connections with steel pins inserted. NOTE: Old sashes often have trouble holding paint.

Therefore, the Contractor must insure that all the mildew and algae has been carefully removed from the cypress sash prior to painting. Note: Any milling of wood requires careful replication and maintaining of tolerances. Wood must be red gulf clear heart cypress.

6. A Benjamin Moore Super Spec oil based paint, or approved equivalent for metal and wood applications (color to be chosen to match) shall be used both as a primer and top coat for all sashes, gable rafters, ridge poles and finials. On V-bar inlays, a careful light coat of paint is to be applied. Painting without build-up is important.

7. Contractor shall replace all the glass on the greenhouse, including the glass in the valleys and missing glass, with new tempered glass. Contractor shall use double sided 1/8” butyl tape, or approved equivalent, as bedding for the glass to help prevent slippage (wood will have previously been primed to receive this tape). All glass needs to be lapped up the slope holding 3/8” to 1/2” laps. Bar caps must have a configuration that laps over one another to serve as a counter flash and assist in preventing water leakage, slippage and to reduce heat loss.

8. Contractor shall seal all the glass edges with gun grade oil based continental caulk #303 or approved equivalent before applying aluminum glazing caps to all glazing bars. Bar caps must have a configuration that laps over one another to serve as a counter flash and assist in preventing water leakage, slippage and to reduce heat loss.

9. Contractor shall remove and store the brass roof pulleys that were designed for exterior roll shades made of redwood at the ridge. Contractor will then install a sheet metal ridge cap made of .040 aluminum flashing and then re-install the brass roof pulleys. This will give the ridge pole longevity and at same time add a counter flash for top sashes.

10. Contractor shall restore\replace all the hardware that functions to hold open the sashes.

11. All mechanical knuckles and hand wheels shall be repaired, cleaned and greased for smooth operation of the manual systems.

12. Contractor shall clean all the gutters/leaders on inside and outside. Missing pipes shall be replaced in kind so as to make the cistern watering system functional. Bolt connections shall be inspected for integrity of fasteners and prepared for paint.

13. The two (2) awnings/canopy shall be stripped, sanded, painted, and re-glazed with 1/8” tempered glazing.

14. Contractor shall refurbish all three (3) exterior and (1) interior doors and door frames. Doors will then be re-hung and made fully operational. Contractor shall be responsible for restoring all hardware and providing any missing parts including galvanized hinges, door knobs, strike plates, screws, etc.

15. Contractor shall completely upgrade the electrical system to meet today’s standards including GFI outlets with rain covers. Contractor shall provide a minimum of ten (10) outlets in the large room and six (6) in the small room. Lighting fixtures must consider historical accuracy and will be confirmed by USMMA.

17. Contractor shall provide and install a complete new steam heating system, including valves and temperature controls, with new perimeter piping. The size of the heating unit shall be a minimum of 100,000 BTU output. A similarly sized electrical back-up system shall also be provided along with a high and low temperature alarms.

18. Contractor shall provide and install two (2) suspended 24”Horizontal Air-Flow Fans and controllers in the large room. Each of these fans shall be 1/2 HP, 115/230 Volt, 5/2.5 Amp, 7784

CFM

18. Contractor shall provide and install (1) one suspended 12” Horizontal Air Flow Fan and controller in the small room. This fan shall be 1/10 HP, 115/230 Volt, .9/.45 Amp, 1554 CFM.

19. Contractor shall provide a hot and cold water source (including mixing valve) for each greenhouse room. Piping must be insulated. Contractor must submit a piping diagram for approval.
