PMIS # 229016 Page 3

The Park will consider alternatives under the Value Engineering Clause of the solicitation documents.

Acceptance or rejection of value engineering is at the sole discretion of the Government.

Unforseen or differing site conditions will be address per the Clause 52.236-2, Differing Site Conditions.

3. Historical Requirements: All construction activities must be consistent with the Secretary of Interior’s “Standards for Treatment of Historic Properties” and the “Standards and Guidelines for Rehabilitation of Historical Buildings.” The Secretary of Interior’s Standards for the Treatment of Historic Properties, can be viewed at http://www.nps.gov/history/hps/tps/standguide/, and should be reviewed by bidders before submitting their proposals. Construction activities shall not adversely affect the integrity or the architectural characteristics of the building(s) in either its interior or exterior expression. Original materials are to be preserved to the maximum extent possible with any demolition, removal, etc., coordinated and approved in advance by the Park if not in accordance with the approved work plan.

4. Description of Work: The work consists of all labor, material, equipment and incidentals to analyze the Historic Structure Report (HSR), develop a work plan, document, and accomplish the required work as described below. NOTE: The Historical Structure Report (HSR) for the Mission San Jose Convento is a comprehensive look at current and future requirements for preserving and maintaining the Convento ruins. Only the portions of the HRS directly applicable to work described below shall be considered/utilized by the selected Contractor when developing their proposal and subsequent work plan.

The format of the work plan is up to the selected Contractor, but it must provide a clear, easily understood, and detailed description of the methodology, sequencing of work, techniques, materials, etc., intend to be used in accomplishing the required work. The work plan shall address all the major Contract Line Items, including Additives, i.e., the broken out “sub-items” under Contract Line Item #3 do not need to be addressed individually, unless there is a unique aspect or for consideration under a particular “sub-item.”

All work shall be documented via photographs and written descriptions of observations and repairs accomplished. Written descriptions shall be annotated on drawings (floor plans and elevations) to ensure clarity on the actual locations, extent of work, etc., etc. The selected Contractor can create their own drawings or use the rectified photos and plans from the HSR, perhaps by simply adding a layer to the existing AutoCAD drawings/files. The Park will provide the AutoCAD files to the selected Contractor.

As part of their work plan, the selected Contractor shall detail how they intend to accomplish this requirement.

The Park will provide access to their supply of tufa stones, sand stones, etc., for repairs/alterations.

Crack preparation (cleaning, etc.), repairs and repointing shall be accomplished in accordance with the HSR and utilize a limed-based mortar matching the existing mortar appearance as closely as possible in a given area. There are formulas for these lime-based mortars in the HSR. Mock-ups of the mixes the Contractor proposes using, shall be provided to the Park in order for them to make a final selection in

PMIS # 229016 Page 4 advance of any repointing occurring. Mock-ups shall include stones. Except for cracks associated with wall movements, all the cracks requiring repair and repoint are stable and won’t require any pinning, etc., to prevent further movement. There is no intent to do any pinning at any location as part of this project.

The cost for biological growth removal (cleaning) in support of specific line items shall be included in that specific line item. Contract Line Item 5 – Additive B for biological growth (cleaning) is for all other areas/surfaces in the Convento, i.e., surfaces not cleaned as part of a specific line item.

NOTE: Historic plasters, including “scratch” coat, whether mentioned or not in the various line items and paragraphs below, shall be protected from damage at all times when the possibility of damage exists from work associated with specific line items. Examples include, but are not limited to placing of a cement mortar cap above historic plasters or “scratch” coat, or removing (cleaning) biological growth adjacent to, above or near historic plasters or “scratch” coat. The selected Contractor shall clearly spell out in their work plan how they intend to protect these historic plasters and “scratch coat” during repair, repointing and other work, as well as how emergency repairs/stabilization will be accomplished if it becomes necessary. There may also be historic plasters and “scratch” coat in locations not previously identified.

The historic plasters and “scratch” coat are located primarily on the underside of the 9 arches that make up the lower section of the South wall, including the arches in the West and East corridors, and Rooms 203 A, C and D of the North Interior Spaces. There are also some small areas of historic plasters and “scratch” coat in Rooms 203 R and K that are not easily noticed/recognizable. See the ground floor plan below for location of referenced spaces.

See the HSR for more detail on the exact location and condition of historic plasters and “scratch” coat.

PMIS # 229016 Page 5

Convento Ground Floor Plan

4a. Contract Line Item 1: Repair/modify/repoint second floor of North wall, Northeast corner.

The specific area requiring work under this line item is the second floor of the North wall above Room 203 B, and a portion of the wall above Room 203 P. The intent of this line item is to stabilize/repair/ modify/ repoint in accordance with the guidelines in the HSR. In order to stabilize the wall, it is possible the selected Contractor will need to disassemble portions of the top of the wall in order to “tie” this section of the North wall into the traverse walls and prevent future movement; however, this will need to be determined by further on-site inspection because early renovation work may have already accomplished this. The final repairs shall accept a new cement mortar cap without any additional work.

Any biological growth removal (cleaning) required to accomplish this work shall be included in this work and not part of the separate line item for biological growth removal (cleaning). Reference the HSR for techniques, materials and methods for removing (cleaning) biological growth.

PMIS # 229016 Page 6

4b. Contract Line Item 2: Add/replace cement mortar caps throughout Convento. New cement mortar caps shall be placed/installed on all walls and “window sills” with the following exceptions:

- The top of the West wall “shared” with the church. This exception does not include the West wall of Room 203 S not “shared” with the church.

- The West “window” in Room 203 R.

The new cement mortar cap on the North wall shall slope outward, i.e., to the North. This is to ensure water runoff is away from the historic plasters and “scratch” coat on the interior of the North wall.

Cement mortar caps shall be sloped away from historic plasters and/or “scratch” coat when present. In all other locations without historic plasters and/or “scratch” coat, the cement mortar caps shall be slightly crowned to facilitate water runoff.

NOTE: Any replacement of stones, repair, repointing, etc., required to stabilize areas below or adjacent to the mortar caps and allow installation of the new cement mortar caps shall be included in this work and not as part of the line item to repair and repoint walls in general. This work shall be accomplished prior to installation of the caps.

NOTE: As mentioned throughout the scope of work, historic plasters and/or “scratch” coat shall be protected all work associated with installation of the cement mortar caps.

The HSR provides detailed information on the exact locations and condition of historic plasters and “scratch” coat.

The new cement mortar cap on the North wall shall be covered by a bituminous asphalt material in an appropriate color to help protect and extend the life of the cement mortar cap. The bituminous asphalt material shall not extend over the sides or otherwise be visible from the ground level. See photograph at the end of this paragraph of an example at Mission Concepcion. A possible alternative to the bituminous asphalt material would be a clear sealant, such as Geocel 2310 Tripolymer Brushable Repair Coating. This coating was used to seal sections of the Mission Espada parapet next to the new TPO roof with good results to date. Belzona Products may be another option.

In areas other than the North wall or lower “window sills”, the Park would like the Contractors to consider using a clear sealant as described above in lieu of the cement mortar cap, provided all necessary repairs were accomplished, there were no voids, and it was felt this solution would be more viable long-term than the cement mortar cap. Installing a clear coating/sealant on top of the cement mortar cap is another option if it is felt this provides a better overall solution. The main concern the Park has in all these cases is the long-term cracking and failure of the cement mortar caps. In any case, except as noted for the West “window” in Room 203 R, “window sills” at ground level shall have a cement mortar cap due to the potential wear and tear from visitors and Church patrons.

As noted above, any biological growth removal (cleaning) required to accomplish this work shall be included in this work and not part of the separate line item for biological growth removal (cleaning).

Reference the HSR for techniques, materials and methods for removing (cleaning) biological growth.

PMIS # 229016 Page 7

Bituminous Asphalt Material Cap at Mission Concepcion

4c. Contract Line Item 3: Repair and repoint walls, “window sills”, arches, buttresses, etc., as needed/required. It is estimated a total of 2,500 to 5,000 sq ft out of approximately 42,000 sq ft of wall surface will need/require repair and repointing. This line item does not include any repair and repointing accomplished as part of Line Items 1 and 2. This work does not include the exterior surface of the East church wall. Contractors shall verify the square footage of repair and repointing required before developing and submitting their proposals.

Except as noted elsewhere in this paragraph, all “window sills” shall receive a cement mortar cap, or alternative, in accordance with and as part of Contract Line Item #2.

NOTE: As mentioned throughout the scope of work, historic plasters and/or “scratch” coat shall be protected all work associated with installation of the cement mortar caps.

PMIS # 229016 Page 8

Other than a window in Room 203 O, Rooms 203 O and P are not accessible from ground level on the outside. As described in Contract Line Item 3a, the “window sill” in Room 203 O will receive a cement mortar cap, or alternative, in accordance with and as part of Contract Line Item #2.

The area below the West “window sill” in Room 203 R will require rebuilding/repair because it has been used as a means to climb up onto the window sill in the past. As described above, this “window sill” will not receive a cement mortar cap. Work plans shall include a proposal for protecting the masonry (stone) wall below the West window from future damage. This protection maybe as simple as cedar wood components assembled to create a screen in front of the wall in this area. Perhaps 2” diameter cedar “posts” tied together and anchored by two larger posts at the end with anchoring boards in between the “posts” at the top and bottom. The intent is for the solution to be something simple and un-intrusive, but not necessarily permanent.

There is a small fireplace/oven on the North wall of Room 203 K. Repair of the fireplace/oven or the wall areas immediately adjacent to it are not included in this project. These areas were repaired in the past 10 years or so. See the photograph below.

Rooms 203 R and K contain small, not easily notices/recognizable areas of historic plasters and “scratch” coat. The selected Contractor shall clearly spell out in their work plan how they intend to protect these historic plasters and “scratch coat” during repair, repointing and other work, as well as how emergency repairs/stabilization will be accomplished if it becomes necessary.

4d. Contract Line Item 4 – Additive A: Based on the Historic Structures Report, on-site observations and investigation, the selected Contractor shall develop and execute a plan for cleaning and preserving the historic plasters and “scratch coat” described in Paragraph 4 and elsewhere in the scope of work. If this additive line item is awarded it shall be appropriately sequenced with other work.

4e. Contract Line Item 5 – Additive B: The selected Contractor shall develop and execute a plan for removing/cleaning biological growth in areas not previously cleaned in support of other Contract Line Items. It is anticipated for this Contract Line Item, and other Contract Line Items requiring biological growth removal/cleaning, the selected Contractor will use a D/2 Biological Solution or a similar cleaner to remove the biological growth. Other products or methods can be utilized with the Park’s approval; however, the selected product or method of removing/cleaning the biological growth cannot damage the underlying masonry (stones) or historic plasters located nearby. Reference the HSR for details and information on techniques, materials and methods for removing (cleaning) biological growth. If this additive line item is awarded it shall be appropriately sequenced with other work.

5. Project Work Conditions and Weather Contingency Plan: The Contractor shall not accomplish any work during adverse weather (rain, sleet, high winds, low temperatures, etc.). Specifically, the selected Contractor shall:

- Not accomplish any work on the historic plasters if weather conditions (temperature, humidity, etc.) are not within “industry” standards, unless protective measures (subject to the Park’s approval) are utilized

- Not place mortar or lay masonry (stones) when the ambient temperature is below or predicted to fall below 40 degrees F within 72 hours, unless means are provided to protect work from cold and frost, and ensure that mortar will harden without freezing.

- Prevent mortar or mortar dust from staining the face of the masonry (stones).

- Protect mortar from excess drying due to sun, wind or high temperature.

- Not accomplish any work during rain, sleet or snow without approved protection. Follow industry approved standards for hot and cold weather procedures.

The Contractor shall provide a Weather Contingency Plan. The Weather Contingency Plan shall detail the steps the Contractor will take to protect ongoing work that could be affected by the adverse weather. The Weather Contingency Plan must be approved by the Park prior to the beginning of any construction work.

6. Quality Control: The quality of work shall be the responsibility of the Contractor. Inspect and/or test all work as needed to ensure the quality of materials, workmanship, construction, finish, and functional performance is in compliance with the statement of work, applicable codes and manufacturers’ instructions, and the approved work plan.

7. Safety: The Contractor shall meet established NIOSH and OSHA safety standards, and also take special care to reduce risk or exposure to the public. There is considerable pedestrian traffic in the general vicinity of the work and Parade Ground and care shall be taken to not impact the visitor’s

PMIS # 229016 Page 13 experience. Mechanisms and/or measures to protect visitors shall be installed prior to the start of and for the duration of work.

The Park’s Contractor Safety and Security Checklist is located at Attachment 3. The Contractor shall review and sign the checklist before the start of construction.

7a. Safety Plan: The Contractor shall provide a copy of their overall company safety plan prior to the issuance of the Notice-to-Proceed (NTP).

7b. Accident Prevention Plan: The Contractor shall provide an Accident Prevention Plan (APP) for the Park’s review and acceptance prior to the issuance of the NTP. The APP is different from the Safety Plan in that it describes how the company Safety Plan will be implemented for this particular project and how they will address/mitigate specific hazards, etc., associated with this particular project.

Fall protection and visitor safety shall be key components of the Accident Prevention Plan.

8. Product Handling: Storage of materials will be permitted only in areas designated by the Park.

Storage of materials shall be in a location safely away from visitor use areas, but as close as possible to the work site. A limited amount of material to facilitate daily work may be stored in the immediate vicinity of the work site. The Contractor shall haul off all trash and debris daily or place in the Park dumpster located nearby, leaving the work area clean unless otherwise authorized by the CO or COR. At the end of construction, and before final payment, the Contractor shall ensure the area is free of material and/or other debris. The Contractor shall comply with all legal load restrictions in the hauling of materials.

9. Recycling/Waste Management: Even though the opportunities to recycle may be limited, the selected Contractor shall employ processes that ensure the generation of as little waste as possible.

Minimize waste generation due to over-packaging, poor planning, breakage, mishandling, contamination, error or other factors. Of the waste generated, as much as is economically feasible shall be reused, salvaged or recycled. Waste disposal in landfills shall be minimized. All material unsuitable for recycling must be disposed of, in a legal manner, at public or private dumping areas outside the park.

Materials that may be recycled include but are not limited to the following:

• Cardboard, paper, packaging

• Clean dimensional wood, pallet wood

• Beverage containers
