1. Project Title: Las Cruces Federal Courthouse Optional Stucco Replacement Design – Polymer Based Finish System on Cement Fiber Panel

2. Project Location: Las Cruces Federal Courthouse 100 North Church Street Las Cruces, NM 88001 Building # NM0061ZZ

3. Description of Work for Optional Stucco System

3.1 Las Cruces Courthouse Stucco Design Guidelines: The Project shall be designed to remove and replace the stucco wall systems.

3.1.1 Refer to all project drawings and other related sections of this specification to determine the type and extent of the work.

3.1.2 This optional stucco method including the specification section represents an alternative stucco replacement solution in lieu of the base bid three part stucco replacement solution. Just like the base solution, this Polymer-Based Exterior Finish System Over Cement Board solution includes removal of the stucco, lathe, and Tyvek membrane. This proposed stucco replacement solution, however, includes leaving the existing sheathing in place as much as possible. Price the work assuming 20% of the sheathing shall need to be replaced due to damage during the stucco removal. This solution requires installation of the waterproofing system specified herein over the existing (and patched) sheathing prior to the installation of the cement board and polymer based exterior finish system. This work is to be priced in the same two phases as the base solution. If this solution is accepted for award, the work will be done leaving all windows in place, except for the windows at the sloped stucco exterior walls, that will be replaced.

3.1.3 Refer to attached Stucco Board detail sheet drawings for stucco panel installation and existing stucco criteria related to this optional method.

3.1.4 Refer to attached option specification: Section 072423 – Polymer-Based Exterior Finish System Over Cement Board.

3.1.5 Cement Board Stucco wall system: composite wall system consisting of air/water resistive barrier, Base Coat, Reinforcing Mesh, and Finish Coat.

3.1.6 Products are listed in the specification to establish a standard of quality.

BASF Senergy is the basis of design. The following cement board based systems are considered acceptable alternates: Parex; Dryvit; and Sto.

Substitutions to the specified systems shall be submitted to and receive approval from the Architect at least ten days before bidding. Proof of equality shall be borne by the submitter.

3.1.7 The Basis of Design (BOD) shall be Senergy Cement Board Stucco (CBS) 1000 wall system as manufactured by BASF Wall Systems, Statement of Work - Option 2 Stucco Replacement Project

July 17, 2019

Shakopee, Minnesota.

3.2 The assumption is that Bidders shall be allowed to remove the landscaping immediately adjacent to the building in order to install scaffolding to complete the stucco replacement. The landscaping will be replaced under a separate contract and are NIC for this stucco replacement scope.

3.3 Assumption is that only a maximum of two trees will need to be removed for the scaffolding to be placed for the work.

3.4 The current opening in the security bollard layout, at the building east side, will be left in place along with the “pad” for a crane for the purpose of the stucco replacement. The successful stucco contractor will be responsible for removing the dirt pad back to match the adjoining grades and uncover any sidewalk that was covered by the dirt pad.

3.5 A second security bollard opening at the paving on the west side of the building will be created during the current roofing work to allow access to the site for the purpose of the stucco replacement. This opening will remain for the work of the stucco replacement. A “jersey barrier” will be placed appropriately to maintain security containment as a part of the roofing rework and left in place for the successful stucco contractor to use.

3.6 New bollards to replace the bollards removed shall be provided under a separate contract and are NIC for this stucco replacement scope.

3.7 Bidders shall assume that one lane of the adjoining Campos Street may be shut down during the work.

3.8 The successful contractor shall be responsible for protection of the newly installed roofing during the stucco replacement. They shall retain the manufacturer for the new roof to monitor the work so that the warranty is maintained. Their contact information is xxxx. As a minimum, the successful contractor shall install 3” of polystyrene directly on the new roof with two layers of ¾” plywood on top as a platform for scaffolding and foot traffic.

Reinforcing Mesh: FLEXGUARD 4 INTERMEDIATE 6 and

INTERMEDIATE 12:

1. Install Reinforcing Mesh where indicated on drawings.

2. Apply mixed Base Coat to entire surface of the cement board with a stainless-steel trowel to embed the reinforcing mesh.

3. Immediately place Reinforcing Mesh against wet base coat and embed the reinforcing mesh into the base coat by troweling from the center to the edges.

4. Lap reinforcing mesh 2 ½" (64 mm) minimum at edges.

5. Ensure reinforcing mesh is continuous at corners, void of wrinkles and embedded in base coat so that no reinforcing mesh color is visible.

6. If required, apply a second layer of base coat to achieve total nominal base coat/reinforcing mesh thickness of 1/16" (1.6 mm).

7. Allow base coat with embedded reinforcing mesh to dry hard (normally 8 to

10 hours).

I. TINTED PRIMER:

1. Apply TINTED PRIMER to the base coat/reinforcing mesh with a sprayer, ⅜" (10 mm) nap roller, or good quality latex paint brush at a rate of approximately 150 - 250 ft² per gallon (3.6 - 6.1m² per liter).

2. TINTED PRIMER shall be dry to the touch before proceeding to the Finish coat application.

J. Finish Coat: SENERFLEX, SENERFLEX TERSUS

1. Apply Finish directly to the base coat with a clean, stainless steel trowel.

2. Apply and level Finish during the same operation to minimum obtainable thickness consistent with uniform coverage.

3. Maintain a wet edge on Finish by applying and texturing continually over the wall surface.

4. Work Finish to corners, joints or other natural breaks and do not allow material to set up within an uninterrupted wall area.

5. Float Finish to achieve final texture.
