1.0 PROJECT DESCRIPTION

The purpose of this solicitation is to provide the design documents for two seed projects to be used as part of the Roofing Multiple Award Construction Contact (MACC). These projects include the partial roof replacement of Building 328 and various roof repairs at Building 7260, both located at Naval Station Great Lakes, Illinois.

328:

Building 328 was built in 1987, and over the course of 32-years, portions of the existing ballasted EPDM roof system have failed. The failure of the roofing system has allowed water to infiltrate the building, causing damage to the ceiling located above the trainer housed inside.

The project includes the removal of an existing and the installation of a new ballasted EPDM (single-ply) roofing system on the upper south roof area (above the trainer) of Building 328; totaling approximately 4,964 SF. Existing stone ballast, EPDM roofing, and insulating roof fill must be removed down to the top of the existing structural steel roof deck. Stone ballast must be salvaged for re-use.

7260:

Portions of the existing standing seam metal roofing system located on the northeast corner of Building 7260, above room 211 (legal offices) and an area in the corridor south of room 206, are prone to leaking.

Identify the cause of the leak(s) and implement the necessary corrective actions to repair the deficiencies.

This includes, but is not limited to: open seams, open penetration flashings, oxidation, fastener backout, open ridge/headwall flashing, loose counterflashing, improper installation methods, panel damage. Any interior damage, caused by leaks, must also be repaired (ACT, GWB, etc.). Damaged interior materials must be replaced in kind.

2.0 PROJECT OBJECTIVES

2.1 Mission Statement

328:

The Surface Warfare Officers School Command Unit’s (SWOSU) mission is to provide a continuum of professional education and training in support of the surface Navy’s requirements that prepare enlisted Sailors to serve at sea.

Masonry-Leak #2 Water drains onto this masonry paraper wall. Mortar joint is open.

OBSERVATIONS:

· Leak #1

· Leak occuring at the valley/roof to wall transition.

· Many repairs have previously been performed at this location with sealant at the seams and a sheet metal pan installed over the masonry wall/sill. Leaking still continues.

· There does not appear to be any recent damage to the roof that would be the cause of the leaking.

· Many of the transitions from the roof to the wall, roof to the sill, valley/end cap we're poorly designed and poorly installed.

· Leak #2

· Leak occuring at the valley/roof to wall transition.

· No prior repairs have been performed at this location.

· There does not appear to be any recent damage to the roof that would be the cause of the leaking.

· Many of the transitions from the roof to the wall, roof to the sill, valley/end cap we're poorly designed and poorly installed.

RECOMMENDATIONS:

· We believe that the source of the leaking at both Leak #1 and Leak #2 is due to the improper design of the roof/sill transition and the improper installation of the sheet metal panels, valley transition to the lower roof, and the end cap at the sill. Removal and reinstallation of new panels and transition flashings is needed for a long term repair to these areas. The issues at both leaks are caused by exactly the same conditions. Recommended work scope applies to both locations.

· WORK SCOPE (Permanent repair):

· Remove all roof panels and associated flashings to 4' above sill or to nearest ridge line on both sides of the valley.

· Remove 10' of "W" valley.

· Remove 1 panel at the roof to wall transition that is below the valley.

· Remove counter flashings at the roof to wall transition that is below the valley.

· Replace deteriorated decking with matching steel/wood decking.

· Cover all areas with Grace Ultra ice and water shield.

· Install 1 new panel and counter flashings at the roof to wall transition that is below the valley.

· Install new sill cover panel and welded/soldered end caps over the masonry sill.

· Install new "W" style valley with hem for locking roof panels into.

· Install new drip edge with hem over the sill cover.

· Install new roof panels locked into the hem on the drip edge and properly seamed into any existing roof panels.

· Install new roof panels locked into the hem on the "W" valley and properly seamed into any existing roof panels.

· WORK SCOPE (Temporary repair):

· Clean and prime transitions and seams in the valley, sill, and sill end caps surrounding the leak location.

· Apply uncured EPDM pressure sensitive flashing to all seams, transitions and deficiencies found on the metal roof and sky joints of the masonry sill and parapet wall surrounding the leak location.

· Apply urethane sealant to deficiencies found on the mortar joints surrounding the leak location.

Pressure-Sensitive Elastoform Flashing®

Overview

Carlisle’s Sure-Seal EPDM Pressure-Sensitive (PS) Elastoform Flashing is a nominal 60-mil-thick (1.5 mm) uncured EPDM membrane, laminated to a nominal 30-mil-thick (0.75 mm), fully cured PS adhesive. This product is available in 6" x 100', 9" x 50', and 12" x 50' rolls and is easily malleable and highly adaptable to irregular shapes and surfaces. PS Elastoform Flashing is self-curing and can be used to fl ash pipes and scuppers, as well as other rooftop structures and penetrations. The clear poly release liner on the 12"-wide product is pre-slit down the center, allowing the applicator to partially remove the liner for ease of installation.

Features and Benefi ts

» Available in 6" x 100', 9" x 50', and 12" x 50' rolls

» Adaptable to irregular shapes and surfaces

» Self-curing membrane

» Labor and cost savings in fi eld applications

Installation

1. The entire surface where the PS Elastoform Flashing will be applied must be clean. The adhesive on the back of the PS Elastoform Flashing will not adhere to dusted or dirty surfaces. Any residual contamination will be detrimental to the bond strength of the adhesive.

2. Remove all foreign material.

a. Remove excess mica dust by brooming or wiping with a clean, dry rag or Carlisle HP Splice Wipe.

b. The use of Weathered Membrane Cleaner may be necessary.

This process is essential on membrane that has been exposed for a number of weeks.

Note: Permeation-resistant gloves (that meet ANSI/ISEA 105- 2005) are required for hand protection when cleaners or primers are being used.

c. Allow the membrane to dry thoroughly before proceeding.

3. Apply HP-250 or Low-VOC Primer per instructions on respective product data sheets. Review Carlisle specifi cations and details for complete installation information.

Note: The use of excessive amounts of primer will not signifi cantly enhance the adhesion of the PS Elastoform Flashing to the EPDM membrane. Use only the amount necessary to obtain 100% coverage of the area where the PS Elastoform Flashing will be applied.

4. Allow the primer to fl ash-off until it does not transfer to a dry fi nger touch yet remains tacky. Install the pressure-sensitive product immediately after the primer has fl ashed-off to promote adhesion and avoid contamination.

5. Position the fl ashing over the area to be covered and press down the exposed tape adhesive using fi rm, even hand pressure across the entire area. Install the elongated diamond pattern parallel to the deck when fl ashing corners around vertical pipe wraps.

6. Immediately roll the PS Elastoform Flashing with a 2"-wide (50 mm) roller, using positive pressure. Roll across the fl ashing edge, not parallel to it.

7. To achieve proper adhesion of the PS Elastoform Flashing when jobsite temperatures fall below 40°F (4°C), heat the primed area of the membrane with a hot-air gun as the fl ashing is applied and pressed into place.

8. PS Elastoform Flashing is used to fl ash many different roofi ng system structures and penetrations. The specifi c method of applying the fl ashing for each individual situation is different. The appropriate Carlisle specifi cation and/or detail must be consulted prior to application.

Review Carlisle specifi cations and details for complete installation information.

Precautions

» Avoid prolonged contact with skin. In case of contact with skin, thoroughly wash affected area with soap and water.

» Prolonged jobsite storage temperatures in excess of 90°F (32°C) will shorten product shelf life.

» In warm, sunny weather, keep PS Elastoform Flashing rolls in their box and in a shaded area until ready to use.

» Storage and use of PS Elastoform Flashing at temperatures below 40°F (4°C) will result in a loss of adhesive tack and, in extreme cases, will result in no bond to the substrate. Overnight storage must be available to keep the temperature of the PS Elastoform Flashing at a minimum of 60°F (15°C). Hot boxes for jobsite storage must be provided to maintain a minimum product temperature of 40°F (4°C).

» PS Elastoform Flashing must be stored in a dry area. It is recommended to store the fl ashing below 80°F (27°C) to ensure maximum formability and shelf life.

» Due to solvent fl ash-off, condensation may form on applied primer when the ambient temperature is near the dew point. If condensation develops, the application of primer and PS Elastoform Flashing must be discontinued as proper adhesion will not be achieved. Allow the surface to dry and reapply primer to the previously coated surface. Apply PS Elastoform Flashing when conditions allow.

» Do not allow waste products (petroleum, grease, oil, solvents, vegetable or mineral oils, animal fats, etc.) or direct steam venting to come in contact with the PS Elastoform Flashing.

» A heat gun is required when forming PS Elastoform Flashing in colder temperatures as outlined in the specifi cation.

» KEEP OUT OF THE REACH OF CHILDREN.

How to Apply Joint Preparation

1. The number of joints and the joint width should be designed for a maximum of ±25% movement.

2. The depth of the sealant should be 1/2 the width of the joint. The maximum depth is 1/2” (13 mm) and the minimum is 1/4” (6 mm). Refer to Table 1.

3. In deep joints, the sealant depth must be controlled by Closed-Cell Backer-Rod or Soft Backer- Rod. Where the joint depth does not permit the use of backer-rod, a bondbreaker (polyethylene strip) must be used to prevent three-point bonding.

4. To maintain the recommended sealant depth, install backer-rod by compressing and rolling it into the joint channel without stretching it lengthwise.

Closed-Cell Backer-Rod should be about 1/8" (3

mm) larger in diameter than the width of the joint to allow for compression. Soft Backer-Rod should be approximately 25% larger in diameter than the joint width. The sealant does not adhere to it, and no separate bondbreaker is required. Do not prime or puncture the backer-rod.

Surface Preparation

Surfaces must be structurally sound, fully cured, dry, clean, free of dirt, moisture, loose particles, oil, grease, asphalt, tar, paint, wax, rust, waterproofing or curing and parting compounds, and membrane materials.

CONCRETE, STONE, AND OTHER MASONRY

Clean by grinding, sandblasting, or wire brushing to expose a sound surface free of contamination and laitance.

WOOD

New and weathered wood must be clean and sound.

Scrape away loose paint to bare wood.

Any coating that cannot be removed must be tested to verify adhesion of sealant or to to determine an appropriate primer.

METAL

Remove scale, rust, and coatings from metal to expose a bright white surface. Remove protective coatings as well as any chemical residue or film.

Aluminum window frames are frequently coated with a clear lacquer that must be removed before the application of NP 1™. Any coating that cannot be removed must be tested to verify adhesion of sealant or determine an appropriate primer.
