Tarryall -Cline Ranch Planning, Design, and Construction Documents Response to Request for Proposal

INTRODUCTION

Thank you for the opportunity to submit this response to the Request for Proposal to provide Park County with planning, design, and construction documents for the historic Tarryall-Cline Ranch House. Given that the Ranch has been designated by Colorado Preservation, Inc, as one of Colorado’s Most Endangered Places since 2018, we are excited at the prospect of assisting Park County in making progress towards rehabilitating the House to its former historic character and giving it new life as a functional community asset.

The Ranch sits on the Cline Ranch State Wildlife Area within the larger South Park National Heritage Area, which is known for its abundance of historic and natural resources. Wiss, Janney, Elstner Associates Inc. (WJE) understands the Park County Department of Heritage and Tourism has worked with other community partners for many years to protect these resources and ensure the preservation and enjoyment of the rich agricultural and ranching history in this region. These efforts are represented in the Tarryall-Cline Ranch rehabilitation project. We believe our local WJE Denver team possesses an effective balance of technical expertise, practical repair approach, and individual passion for our work and community that will be beneficial to the sensitive and regionally significant work at the Tarryall-Cline Ranch. Our Denver office has a qualified interdisciplinary team of in-house Structural Engineers, Architects, and Geotechnical Engineers to address the intricacies of this project. Additionally, we have WJE’s national resources at our fingertips, including expertise from professionals at our thirty offices and Material Scientists at our materials and testing laboratory.

We have assembled an experienced team to demonstrate our unique qualifications. WJE and our subconsultants, 360 Engineering, enLighten Engineering, and ATC Group Services, look forward to the opportunity to assist Park County in the successful and rewarding completion of this project. Please review our attached submittal, and if there are any questions or you need any additional information, please feel free to contact us at your convenience.

PROJECT BACKGROUND

The historic Tarryall-Cline Ranch was acquired by Park County in 2010 in conjunction with Colorado Parks and Wildlife to establish the Cline Ranch State Wildlife Area. The previous owner placed the 1,635-acre property under a conservation easement, setting aside the 10-acre Ranch headquarters and surrounding area for use by Park County. The Ranch sits within the larger South Park National Heritage Area, which is managed by the South Park National Heritage Area Advisory Board. A Historic Structure Assessment (HSA) of the Ranch headquarters was conducted in 2011 and a Master Plan completed for the site in 2016 in conjunction with the South Park National Heritage Area. According to the HSA, the Ranch has been mostly unoccupied since about 2001.

The Tarryall-Cline Ranch Main House (the House) is one of several buildings comprising the Ranch headquarters area, located off of Highway 285 between Jefferson and Como, Colorado. The two-story, wood framed building was built in 1928. The House is an example of the Pueblo Revival style, with Spanish Eclectic influences, and was an unusual application for a working ranch in Colorado at the time. It has a concrete foundation with rubble masonry veneer, stucco cladding, and a flat roof with a distinctive

WJE No. 2021.1928 | APRIL 6, 2021 Page 1

Tarryall -Cline Ranch Planning, Design, and Construction Documents Response to Request for Proposal

parapet that was over framed with a shingled gable roof in the 1980’s. The main entrance is on the south facade, which has a prominent, full-width rubble masonry porch with a hipped roof. The interior layout is largely unchanged and features original wood flooring, rubble masonry fireplaces, finish carpentry, cabinetry, doors, and some original plaster work. Attempts have been made to modernize the building, but the plumbing and electrical are non-functioning and there is no mechanical heating, cooling, or ventilation system. Currently, the House does not meet accessibility standards. The House has severely deteriorated over the years from disuse and harsh weather, most notably the foundation, stucco, and original wood windows. Several tactics have been employed to stem the deterioration, such as temporary stabilization and polycarbonate window coverings.

WJE understands Park County wishes to move forward with repair work on the House, building off the design intent for the House given in the Master Plan, by having construction drawings prepared for use by a qualified contractor. The scope of the repair work, as laid out in the Request for Proposal, includes planning, design and construction documents for rehabilitation of the foundation, structure, building enclosure, and interior of the House only, as well as design for site drainage immediately around the House. Based on the Request for Proposal and preliminary discussion with Park County’s representative, Mr. Lockhart Borman, we recognize Park County’s goal is to protect as much of the historic fabric and context as possible, while providing a code compliant, functional space for public use on the first level. While use of the second level has not yet been determined, the Master Plan suggests a groundskeeper residence.

It is WJE’s understanding that the House has no formal historic designation, but the repair work will be governed by guidelines and regulations set forth by the conservation easements, Park County, the South Park National Heritage Area, and stakeholders. We reviewed the provided documents, including the HSA, Master Plan, Conservation Easements, and Hazardous Material Sampling Report and visited the site with Park County’s representative prior to completing this proposal.

PROJECT APPROACH

WJE is uniquely qualified to complete the majority of the required scope of this project with in-House resources, which is convenient for Park County and expedites communication. The design of the repairs will be approached with a clear understanding of the history, context, and current condition of the historic structure, gained through collaboration with Park County and initial thorough evaluation. Our repair solutions will be thoughtful and draw on our technical expertise to ensure a combination of durability and historic appropriateness. We will prepare technical specifications and repair details that address issues such as salvageability, suitable repair materials, sources of replica components, and abatement of potential hazards. Although not specified in the Request for Proposal, we typically perform construction phase services and observations to confirm that the restoration work is carried out consistent with the construction documents.

WJE No. 2021.1928 | APRIL 6, 2021 Page 2

Tarryall -Cline Ranch Planning, Design, and Construction Documents Response to Request for Proposal

Based on discussions with you and the provided documents, WJE’s main design approach will be governed by rehabilitation, with some areas of restoration and renovation, as described by the Secretary of the Interior’s Standards for the Treatment of Historic Properties. Although some aspects of the Tarryall- Cline Ranch project are unique, many of the issues to be addressed are common conditions resulting from the deterioration of existing structures. Whether unique or common, we are able to draw on our collective knowledge to confidently approach these repairs.

SCOPE OF SERVICES

The scope of services includes planning, design, and construction documents for rehabilitation of the foundation, structure, and building enclosure, and site drainage design immediately surrounding the site. It also includes planning, design, and construction documents for the rehabilitation and renovation of the interior for public use, with a potential second story groundskeeper residence and including mechanical, electrical, and plumbing. The design of concrete flatwork, such as sidewalks and driveways, and landscaping are not included in this proposal. Although the documents may plan for construction phasing, documents for the full scope of work will be issued at one time, within 6 months of Park County’s acceptance of the proposal. Based on our understanding of the project, as outlined above, the Request for Proposal documents provided, our experience with similar projects, and our preliminary discussions with you, we propose the following phased scope of services for the House. Pre-Design Phase Services

The project will kick off with an initial consultation and site walk with the project stake holders to discuss project goals, such as design intent and project phasing. While we have had the opportunity to review the previously prepared reports and documents, the building appears to have deteriorated beyond the recorded information based on the site visit. To capture the current conditions, WJE will perform an assessment to determine the extent of the salvageable materials and structure and inform the repairs. The building enclosure, interior, foundation, structural framing, and site drainage immediately around the House will be evaluated. WJE will prepare preliminary structural calculations to assess the existing structure for gravity and lateral loads and conduct a visual assessment of the soil conditions. An asbestos sampling report has already been completed for the House, but no lead paint sampling has been performed. Therefore, ATC Group Services will perform sampling at this time to determine if lead paint is present. This assessment will also include recommendations for additional material testing that are not included in this proposal, such as petrographic analysis, that cannot be anticipated at this time.

The results of this initial assessment will be reported in a summary memorandum. We anticipate 2 site visits in this phase to complete this work. Costs associated with a site survey, which is needed for accessibility design, have not been included in this proposal. If desired, WJE can revise our proposal to include these services.

WJE No. 2021.1928 | APRIL 6, 2021 Page 3

Tarryall -Cline Ranch Planning, Design, and Construction Documents Response to Request for Proposal

Design Phase Services

During the Design Phase, WJE will develop the documents necessary to delineate the full scope of the project. These documents will include, but are not limited to, plans, details, schedules, specifications, diagrams, and a cost estimate. We will perform up to one site visit per design phase listed below, if necessary, to verify and observe as-built conditions as they pertain to our design.

Schematic Design (SD): Draft SD Documents will be issued to Park County for review and comment. Feedback provided to WJE will be integrated into the repair documents as appropriate. Final SD documents will be issued at 100% for review, including a design concepts assessment, and a basis of design report. WJE is also including up to ten paint sample analyses to determine original paint colors. WJE will conduct a meeting with Park County to review comments and feedback on the 100% SD Drawings.

Design Development (DD): Feedback on the 100% SD Drawings will be incorporated into the DD Documents as appropriate. Draft DD Documents will include Division 1 Specifications and Division 2-49 Outline Specifications. They will also include a schedule of salvageable doors and windows. These DD Documents will be provided to Park County for review. WJE will then incorporate Park County’s comments, as appropriate, into the 100% DD Documents. The 100% DD Documents will be issued to Park County, along with the Division 1 Specifications, Division 2-49 Outline Specifications, and a product file. WJE will then conduct a meeting with Park County to review comments and feedback on the 100% DD Documents.

Construction Documents (CD): WJE will incorporate the 100% DD feedback into the CDs as appropriate. A Draft CD set will be provided for your review and comment. A cost estimate based on the Draft CDs will also be submitted for review at this time. Based on the feedback provided, WJE will incorporate appropriate modifications and finalize the documents. The 100% CDs will be issued, along with finalized Division 1-49 Specifications and cost estimate and a Statement of Structural Tests and Inspections. Note that general parameters and performance requirements for mechanical, electrical, and plumbing related work will be outlined within WJE’s documents, but design of these elements will be delegated to and provided by our subconsultants as outlined in the “Proposed Subcontractors” section of this proposal.

Presentation: WJE will prepare a presentation for the Park County Board of County Commissioners. Bid Phase Services

WJE typically provides support services during the bidding and contract negotiation process. As defined by the Request for Proposal, the following services are not included in our fees; however, WJE can provide a proposal for these additional services, if requested:

° Collaborate with the Park County to develop a list of approved bidders for the project. ° Conduct a pre-bid meeting at the project site with Park County and the selected bidders to walk- through the scope of work and discuss site logistics and other factors impacting implementation of the work. ° Respond to contractor questions during the bid phase and, if required, prepare an addendum prior to the bid due date to incorporate appropriate changes. ° Develop a bid summary and participate in one conference call with you to discuss the bids received.

Tarryall -Cline Ranch Planning, Design, and Construction Documents Response to Request for Proposal

Construction Phase Services

Taking a project from the pre-design stage through to the completion of construction is routine for WJE. Continuity of staff across project phases is enhanced by our collaborative work environment and team approach to working on projects, which allows for important information to be transferred effectively from the evaluation, to the design, and ultimately to the construction phases of the project. During implementation of the repair work, WJE typically provides construction phase services to evaluate whether the contractor’s work is in general conformance with the construction documents and help address unforeseen conditions uncovered during the construction process. As defined by the Request for Proposal, the following services are not included in our fees; however, WJE can provide a proposal for these additional services, if requested:

° According to the Request for Proposal and the Master Plan, repairs at the House will most likely occur in multiple phases. WJE recommends we attend one pre-construction meeting at the project site with the contractor and client prior to the start of work activity at each phase. ° Participate in regularly scheduled owner-architect-contractor (OAC) meetings intended to discuss the schedule and progress of the work, as well as construction or operational issues that require discussion and resolution. ° Conduct site observations of critical in-progress work, such as mock-ups and waterproofing or masonry repairs. ° Review product submittals and shop drawings, respond to Requests for Information (RFI’s), and provide necessary contractor support with respect to clarifications of the construction documents, historic requirements, and technical questions that arise as the work proceeds. ° Perform a final inspection of the contractor’s completed work at each phase and assist in identifying conditions and/or issues to be included on the contractor’s punch-list of items to be corrected before release of final payment. ° Issue a letter of substantial completion at the end of the project, which will establish the initiation date for the installer and material warranties. Please note that WJE’s involvement during the construction phase is required to issue a letter of substantial completion. Additional Services

While at this time we do not anticipate they will be necessary, additional conference calls, in-person meetings, or other requested services beyond those specifically outlined in the Scope of Services section above can be arranged at your discretion. These additional efforts will be considered Additional Services and will be billed on an hourly plus reimbursable expense basis using the hourly rates in effect at the time the services are provided.

Further, while adjustments to the design are anticipated to occur as a result of further refinement and coordination amongst consultants; substantial changes to the design and layout of the project or significant value-engineering of the project that requires substantive changes cannot be reasonably anticipated at this time. As such, responding to such changes will be viewed as Additional Services.

PROJECT PROFILE Old Santa Fe Trail Building WJE Investigation and Rehabilitation of the Exterior and Seismic Systems | Santa Fe, NM

CLIENT WJE was engaged to offer independent conceptual recommendations regarding Mills and Schnoering Architects, implementation of an exterior rehabilitation effort and potential seismic improvements. WJE LLC on behalf of the National Park advised NPS on the appropriate level of intervention and seismic retrofitting warranted by the Service (NPS) existing conditions and site-specific soil conditions. The goal of the review was to provide the building with historically compatible, technically appropriate, and long-lasting repairs. BACKGROUND The Old Santa Fe Trail Building (OSTB) in Santa Fe, New Mexico SOLUTION was built between 1937 and 1940 by the Civilian Conservation Corps To determine appropriate retrofitting and repairs, WJE reviewed and the Works Progress documents associated with the building from the time of original Administration to serve as the construction to the present and performed a seismic assessment. WJE headquarters for the NPS reviewed site seismicity and performed a geotechnical investigation to Southwest Regional Office. It was correctly characterize site soils. Nondestructive testing was undertaken designed by Architect Cecil J. Doty to determine if observed distress to the plaster finishes could be in the Spanish-Pueblo Revival style detected in the underlying adobe masonry. A survey of vigas (wood and is the largest adobe office beams that project through the walls to the exterior) and other wood

building in the United States. In elements was performed to identify recommended repairs. 1987, it was designated as a Based on research and investigation, WJE determined that the site was National Historic Landmark. It in an area of moderate seismic risk and developed historically sensitive currently serves as an seismic repairs appropriate to this risk level. In consultation with NPS administrative building for staff and the New Mexico SHPO, WJE recommended that the cracked, approximately seventy NPS multi-layer, cementitious plaster system be removed, and the plaster employees who work in supp ort of restored to its original thickness and profile. the Intermountain Region and the

National Trails System. WJE prepared comprehensive drawings and specifications for historically

appropriate seismic repairs and for complete exterior rehabilitation. WJE

also designed viga repairs and new roofing and flashing systems to integrate with the restored cementitious plasters. During construction, WJE provided construction administration services.

CLIENT During a spring blizzard, the central portion of the main barn’s roof collapsed; additionally, the Shea Homes framing for its lower roofs and for the roof of the south barn were badly damaged by the weight of the heavy snows. WJE was retained to investigate the cause of the collapse and structural distress BACKGROUND and to develop repair designs for the historic main barn and south barn. The Highlands Ranch Historical Barn and adjacent buildings were home to a ranching and dairy operation in the late 1800s. They remain part of a working ranch that SOLUTION is still in operation today and serves WJE engineers conducted a condition survey of the partially collapsed as a valuable piece of history, structure and evaluated the distress and distortion of the framing. Based reflecting the lifestyle of early on the inspection, WJE generated rough as-built drawings and developed settlers. Typical roof framing a shoring/demolition plan. Because certain original structural elements in consisted of heavy timber trusses the historic main barn did not satisfy current code provisions, the and rough sawn 2x6 rafters. engineers recommended the installation of unobtrusive sister members at each rafter location and designed new shear walls in the main barn to provide the lateral stability required by current code.

WJE also redesigned the original clerestory roof of the barn using truss members to eliminate horizontal thrust loads that contributed to the collapse and developed a jacking scheme and supplemental connection details to lift and stabilize the roof of the south barn. Finally, WJE provided construction observation services to ensure repairs were completed in accordance with the project specifications—a remedial plan that met current code requirements yet did not change the geometry or diminish the aesthetics of the barns’ original construction.
