EXECUTIVE SUMMARY
The Alderfer Barn is an important architecture feature of the Evergreen area. It has been modified and added to over the years, but has remained an iconic fixture and gathering place for the community. Evergreen Parks and Recreaction District currently utilizes the space for various actives. The building does not currently have a Certificate of Occupancy (CO) and J.F. Sato and Associates and D2C Architects were contracted to explore the existing conditions and what would be required to obtain a CO. There were four main items to be addressed in this report.
Document the existing conditions of the structure and architecture using photographs from a December, 2015 site visit and as-built plan sheets based on measurements taken at the site.
Evaluate the existing conditions and identify all modifications recommended for continued maintenance as well as for a Certificate of Occupancy from Jefferson County. This is based on several different occupant criteria as determined by Evergreen Parks and Recreation District.
Evaluate basic structure to identify major deficiencies and provide general assumptions for improvements. Calculations and load path analysis to be provided with repair project.
Provide probable construction cost estimates information for repairs and modifications recommended from the evaluations. These cost opinions are based on 2015 RS Means construction assemblies and past project information. Cost estimates are limited as to what is included and is described further in Appendix C.
Low End Estimate High End Estimate Required Improvements $19,200 $26,800 Recommended Improvements $29,400 $49,000 Fire Suppression System $80,570 $95,570
*all costs are additive
The focus of this report is on maintaining the barn for use by Evergreen Parks and Recreation District. It also provides information on what the limitations of use are currently and what modifications would be needed to provide expanded use.

INTRODUCTION
The Alderfer Barn started as a small log barn built in the 1850s as part of the Hester Homestead located near present day Evergreen, Colorado. A timber frame addition was added in 1900 and again expanded in the 1970s. The barn was obtained from the Alderfer family by Jefferson County Open Spaces in 1985 and is currently operated by Evergreen Park and Recreation District.
The barn consists of multiple levels and is accessed by several different stair systems and doors located around the perimeter. As-built drawings showing these different levels are provided in Appendix B. For the purposes of this report, the different levels will be identified as the Basement (Elevation 91’-9”), Shop (Elevation 95’-0”), First Floor (Elevation 100’-0”), Gathering (Elevation 104’-1”), Mezzanine 2 (Elevation 108’-1”), Second Floor (Elevation 114’-3”), and Attic (Elevation 124’-0”). See Appendix A for documentation drawings.
The barn is located in the Alderfer/Three Sisters Park which provides hiking, mountain biking, and horseback trails, climbing, and picnicking opportunities. Previously, the Alderfer Ranch raised cattle, horses, and foxes. Hay was cut from the adjacent meadow and an operational sawmill was located nearby. Some of the boards for the barn came from that sawmill.
Over the years, the barn has served many purposes. In the past few years, the barn has been the location for several events including weddings and a music venue for Boogie at the Barn. J.F. Sato and Associates (JFSA) was contacted by Evergreen Park and Recreation District to provide a report to summarize modifications and probable construction cost opinions to obtain a Certificate of Occupancy. The purpose of this Certificate of Occupancy would be so that Evergreen Park and
Recreation District could offer more program opportunities within the barn. To this end, JFSA teamed up with D2C Architects to provide documentation of existing conditions, modification recommendations, and probable construction cost opinions. The following report describes JFSA’s findings based on the evaluation of the structure and site visit, and retrofit recommendations.

OBSERVATIONS AND EVALUATION Architectural Observations and Evaluation REQUIREMENTS Code Analysis Building Current Codes:
2015 International Building Code 2015 International Fuel Gas Code 2015 International Mechanical Code 2015 International Plumbing Code 2015 International Existing Building Code 2009 International Energy Conservation Code 2014 National Electrical Code
Occupancy | Use Mixed Use: Assembly (A-3) + Storage
▫ “Club” (With Alcohol Potentially, Baseline – No Alcohol)
Zoning: C-O: Conservation Zone Parking Requirements: Exempt
o Minimal Parking on site exists, and will need to be addressed on a per use basis for the barn.
The existing building is not in conformance with the current or even recent codes for the intended and desired uses, which will require numerous modifications. The recommendation to meet current codes and ensure an Occupancy Certificate will be based on fiscal feasibility and shaping the District’s expectations for how the facility is used. Simple facility management techniques, such as the type of storage in the building and the access to storage space to avoid user/visitor confusion.
Fire Department
The Life Safety aspects will be reviewed and managed by Evergreen Fire Rescue and must conform to the current NFPA codes (2016).
Key Requirements that need to be addressed through a renovation project:
Exit Signage Emergency Lighting Fire Extinguishers Fire Sprinkler System (if occupancy is desired to be over 300 or
over 100 with alcohol served) ▫ May not be fiscally feasible
Posted Occupancy Maximums
5
Zoning Parking Requirements may be exempt with the facility on government land. The Jefferson County Zoning and Planning Department will provide necessary assistance with parking and road safety management. The District will need to coordinate events.
Health Department The existing building does not have plumbing for permanent restroom/ toilet facilities that would be required, typically, of a building which is occupied by the public. With the existing and pseudo-historic function of the barn facility as a storage building that is being used for limited event activities, the Health Department will allow the District to augment the permanent facility with setup of temporary facilities (chemical toilets) during public use. The requirements will be to work with Health Services to apply for use permits and facilities (toilets and wash units). Health Services has confirmed that the number of toilets and wash facilities are based on the occupancy of the event and also that they do not regulate the chemical toilets and frequency, which means that the District has complete flexibility to request/provide as many necessary for any event they plan (no limitations to extent of days). Handicap facilities may also be required for certain events and should be coordinated with Health Services when permitting for public events.
BUILDING EVALUATION Roof
The Barn Roofs, primarily covered with a standing seam metal are in good condition with serviceable life (estimated 10 – 20 years) left, if maintained (includes paint/patch damaged areas, replace nails, repair flashing, etc.). The current roof is understood to be about 15 years old (2001 install) with a warranty still in place (estimated as a 30 year roof) and the roof will likely outlast the warranty. When the time comes to replace the roof; a similar panel/finish will cost between $6 and $7 per SF (current day pricing, including materials, labor, and contractor profit and overhead) plus inflation. Budgeting for $38,000 - $43,000 (includes inflation to 2030) is recommended. It appears replacing the roof in 2030-2035 with a new roof would be appropriate.
6
The structure appears to need some reinforcement on the large expanses that are showing some sagging. Walls
The Exterior Walls of the barn are log and wood sided with minimal or no insulation. The walls could use some patching and tightening up to keep snow/ rain out and to ensure a more air/ weathertight enclosure. If/ when the barn is re-sided, it would be recommended to add sheathing/ weather barrier/ rigid insulation as underlayment to enhance the performance and meet current or future energy codes, which will also extend the life of the structure.
Doors and Windows
Safety Glazing is required in doors and in windows adjacent to doors or within close proximity to the floor or stairs. The current building is nearly compliant with this requirement but the window near the main Entry should be repaired. Existing windows are single pane in-place constructed, fixed. Insulated glazing could help enhance the overall comfort of the building but would be considered as an upgrade. With the use of the building as a non-occupied regularly, building, with existing fenestration and no plan for an overhaul it is not a requirement at this time. Trimming out existing windows will go a long way toward sealing up the envelope and bettering performance.
Door Hardware is mostly non-existent on exterior doors as the structure is set up as for barn/ storage use. Manual locking latches, as existing, should be allowed so long as during use the exit doors are open and accessible. It will be required to have proper push/pull and mounting heights for any doors that the public needs to access.
Floors
Floors are constructed of sawn lumber and have a historic value to the barn. For the most part the floors are in solid shape but overall need to be maintenance to ensure extended life. Replacing, failing units, fasteners, and addressing ADA issues needs to be done in a renovation project.
7
Fire Protection
Fire Extinguishers are in place throughout the Assembly area. The extinguishers need to be signed and mounted to meet current codes and the overall quantity needs to be addressed and illustrated on a Code/ Evacuation plan along with Egress paths.
Sprinkler Requirements for the Barn are based on use/ type of Assembly:
Alcohol Served 100 Occupants Max – Sprinkler Required No-Alcohol Served 300 Occupants Max – Sprinkler Required
ADA Requirements
The primary shortcomings of the barn structure are the conformance to the Accessibility Code (ADA); the building was just never designed for Assembly and the design/ construction dates were far prior to development and intentions of the Accessibility Act. The primary challenges can all be remedied:
Egress/ Ramps + Stairs
The ramp from the exterior through the large barn door needs to be flattened out to be 1:20 sloped floor rather than a ramp to avoid handrails and other material changes.
The ramp inside the main entry area that accesses the lower “Dance Floor” needs to be rotated and extended to meet 1:12 slop and a handrail needs to be added.
The main stair area appears to conform, but the risers should be closed to ensure safety.
8
An additional stair should be added from the “Stage” to the upper “Dance Floor” to allow a 2nd accessible exit.
Handrails
Stair and Ramp handrails need to have conforming handrails with extensions (currently missing) to meet the accessibility code.
Guardrails
The guardrails at the upper “Dance Floor” and Mezzanine overlook do not meet code. There is a requirement for the openness of the rail to “not exceed” and the “Top” is of a rough wood/ tree material which has knots, knobs, cracks, and other unsafe features. The top can have character but receive treatment to ensure code is met.
Obstructions
Head knockers (low overhead obstructions) in the form of structural bracing should be adjusted and dealt with.
9
Trip Hazards
The flooring, where failing, or “character” from knots and splinters missing, needs to be repaired, by replacing planks and sanded in areas to ensure a floor within the change tolerances necessary to meet code.
Heating/ Ventilation
The barn is not heated currently and although events are not currently planned for winter months, it would be a benefit to the longevity of the structure to have minimal heating to assist with maintaining a more stable temperature, especially with the deep freezing. In addition to shoring up the structure for snow loading, and tightening up the envelope, so does including an HVAC system of some kind to temper the space and extend the buildings life and also usability.
Electrical
The existing Electrical Service appears to be minimal but is probably adequate overall for the building as it currently operates. Upgrade to the service with many additional circuits would be required to more efficiently and effective use of the building as an Event venue. The power in the basement that was used for numerous shop activities is unnecessary and an engineer should be consulted to see if the distribution could be shifted to the stage and assembly areas and/ or determine the additional requirements/ loads that should be accommodated. The conduits, boxes, and wiring need to be fully evaluated by an engineer to determine code conformance and recommendations for renovation. The barn does not contain any data wiring for telephone, internet, or cable/ satellite TV. The district shall determine and advise the design engineers, at the appropriate time in a renovation design project, needs and desires they have.
Use Discussion Health Department:
What will be your source of water? N/A, there used to be a pump to get water from the Caretaker house. We are at a loss currently on whether it is recommended, required, or feasible to get water.
How will water be provided to participants? Drinking Water in the past was handed out in bottle form from a Tent outside the barn
10
How many events do you anticipate? Let’s ballpark 10 per year but need to understand requirements up and down from there so Evergreen can make informed planning decisions.
How many people do you think will participate in an event? I would expect from 50-200 per event, but this is a currently a guess; I have put in a request to Evergreen to see if they know a Boogie at the Barn participant level.
What is the maximum occupancy this building could have? We are projecting with the Assembly Occupancy right around 250. If the client wants to cater alcohol they’ll need to limit occupancy to less than 100, as sprinklering the building is not going to be feasible. Past “Boogie at the Barn” events have been attended by 250 – 300 participants.
What do you mean when you say it will be used on a “limited basis”? The Facility is NOT heated and so the client only intends to use in summer months and has only expressed the desire to use a handful of times for Boogie at the Barn and other line dance events. Not being part of their organization and knowing exactly what they might do, I would expect that a process agreement for use and a number of uses may need to be designated.
Are there any restroom facilities available now? Correct, no waste piping available. I assume not, but thought I would ask.
What would be your provision in the way of portable toilets and hand washing facilities? I’m looking to inform the client as to what requirements they should follow. Adding permanent plumbing may not or is most likely not feasible because of maintenance, first cost, and anticipated, limited use.
What type of community events do you see this structure to be used for? Music and Dancing is really as far as they have defined. Boogie at the Barn for instance is the past, on-going event that is held 3-times a year and if Evergreen can get a CO they would like to had another handful of event opportunities. Truthfully, they are looking to know what they can do and then work on a plan from there.
Summary shared with Building, Planning/ Zoning, Health, and Fire:
Alderfer Barn Project Synopsis
Client: Evergreen Parks and Recreation District
Goals:
1. To gain a Certificate of Occupancy for Assembly Use [Boogie at the Barn, Small Band Assemblies, Line Dancing, Community Events]
- Ensure a Safe Event Venue for Limited Use [Main Levels only - Basement, Ancillary facilities, and Attics used for appropriate storage, only]
- Ensure Modifications bring the facility amenities up to the necessary needs for envisioned events/ use.
11
- Ensure Rules, Regulations, and Agreements can be created [Restrooms, Parking, Catering, Etc.]
2. The District has prioritized their needs and hopes for the building use and fiscally they will proceed to achieve the High Priority/ Lower Occupancy/ Lowest Cost of Construction and work their way toward accommodating larger events in the future.
USE PRIORITIES [for the District] High Priority [Use during summer and fall months]
1. General Recreation Programs – Examples: Dancing, Outdoor Camps, Trail Education Classes or Running Programs, Outdoor Education Classes or Skills Days, Fitness (yoga), Jr Mountain Bike, Cultural Arts (Photography Class or Painting Classes).
2. Small Venue Events – Rentals (up to 75 participants) to align with our Park Permit Request and tables & chairs available. Birthday or Family Gatherings (Reunions, Wedding Rehearsal, Community Gatherings, “like concert in the park.”
a. Occupancy over 49 participants will require a 2nd Exit from the main assembly space.
Medium Priority
1. Events for 99 or less attendees (Daily and Hourly Rentals - No alcohol permitted) a. Requires adhering to health department use permitting.
Low Priority
1. Large Special Events (+100 with alcohol), Limit to 3 times a year – example Barn Dancing with Music. Use Permits will be required with the Health Department in addition to coordinating with the Fire Department to ensure life safety measures are adhered to.
a. Occupancy over 100 participants with alcohol served will require the barn be fully sprinklered if the events are held within the barn. Events may be held outside the barn without a sprinkler and would need to be coordinated with the Fire Department.
Key AHJ Reviews:
▫ JeffCo Building Department [Building Approval - Code Compliance]
▫ JeffCo Planning and Zoning [Site Approval]
▫ JeffCo Health Department [Restroom Facilities]
▫ Evergreen Fire [Life Safety]
12
The Architect and Engineering team (JF SATO and D2C) have been hired to conduct an initial study for Evergreen P+R to investigate the facility's structure, code compliance issues, condition of materials within the interior and exterior envelope, and to ultimately determine within the requirements for gaining a C.O. what is required for a construction project and to outline for the District a plan and series of requirements and options. The 4+ level Barn is set up for activity on the main level and raised viewing area, primarily in an open space that is roughly 2000 SF and is supported above by 2 levels (Attics) and a basement totaling about 4000 SF of storage. The Exterior condition of the building is fair, considering it is an un-insulated barn, but the interior will require some upgrades to meet accessibility and safety requirements of the code. Some Structural stabilization will be recommended, and upgrade to the overall electrical service and infrastructure is recommended. No site changes are currently proposed, although it is conceivable that if Evergreen can come to an agreement with JeffCo Open Space regarding parking use for events, that a walking path should be coordinated.

Structural Observations and Evaluation The information listed below is based on observations from a site visit performed on 12-16-15 by JFSA personnel Crystal Backhaus and Ake Boonlert. The full log of photographs is located in Appendix A. Roof The whole exterior roof was a standing seam metal roof and appeared to be in good condition. The roof was only observed from the ground, but no rust areas, bent metal, or other blemishes to the metal were observed. The roof above the second floor on the south side visually appeared to have a large amount of deflection. A portion of the roof to the East was covered by snow and could not be observed at the time of site visit.
The underside of the roof appeared to have water stains from previous weather, presumably prior to the installation of the metal roof system. It was observed on the second level that original roof material was left in place and the addition built on top.
Insulation was also visible through the original roofing material. It was unclear from the site visit what thickness and final extents.
Deflection Area
Water damage, warped, long span
Previous Construction
Existing joists and wood singles
Attic Addition
Visible Insulation
14
Support of the upper roof (visible from the second floor) is questionable.
Walls The walls appear to be mainly all original. In locations all around the structure, the exterior boards have warped, checked, have several air gaps, and been weather damaged at the lower portion of the building. Some repairs should be made although the appearance is part of the structures ambiance.
15
Plexiglas windows were observed and appear to be in good condition. Other windows appeared to be boarded over.
At the first floor and mezzanines, the walls were covered on the interior with plastic, wood panel, and plaster.
Doors located around the perimeter appeared to be warped in some locations, but operational.
Floors and Joists The floor boards appear to be in good condition structurally. No loose boards were observed. Boards did show signs of wear and made noises when walked on.
16
Joists supporting the floor system also appeared to be in good condition. A few locations need further analysis, minor repair, or additional support. (Photo 23, 82, 54)
No blocking was observed in the joists and some connections appear to be missing.
There is a small storage loft located off the Mezzanine 2 level that had some modified joists. It appeared that the bottom of the joists was planned off to provide head clearance and some checking and rolling of the support beam was observed.
Cracked JoistDiscontinuous
Joist Support Missing
Minor Damage
17
Posts and Supports Several repairs and/or analysis of connections should be done located throughout the structure.
Some connections need to be check to confirm that load transfer is adequate. Connections and straps were not observed, so shear transfer through the connections need to be verified.
Checking at Base of Column
Checking in Column
18
The attic space stairs support column does not continue down to the foundation, but is instead supported by the floor boards and then into the joists. There doesn’t appear to be distress.
Foundation
The foundation appeared to be founded on bedrock. In several locations within the basement, rock protrusions were observed. Because of this, no settlement problems were observed with the structure.
Stair posts located in the basement were supported by the concrete floor. Some posts showed discoloration and ckecking located near the base.
A sump pit was observed in the basement and it was noted by Evergreen Parks and Recreation staff that water is often observed several inches deep on the floor.

APPENDIX C
COST ESTIMATE INFO
SUMMARY OF COST – Architectural, Electrical, Fire Suppression The team has identified cost opinions (ranges) for construction modifications, both required and recommended for the best of the long-term facility vision, taking into account the function and use expected in the barn. Note the costs in this appendix do not include Contractor or Architect fees or expected ancillary costs for the project(s) for permitting, insurance, and general overhead that will or may be required. A complete budgetary estimate can be assembled once the scope of project(s) can be identified. The cost estimates listed below are additive. (Total cost for optional/recommended improvements would be the listed costs below “Required” + “Optional/Recommended”. For purposes of estimating, the General Contractor costs for management, procurement, profit and overhead, etc. can be estimated as approximately 10-15% of the costs below. Some possible cost savings could be achieved by owner management. Required = $19,200 - $26,800 Optional/ Recommended = $29,400 - $49,000 + $80,570 - $95,570 to have a Fire Suppression System [Required for Higher Assembly Occupancy and Alcohol provision] COST ESTIMATING – ARCHITECTURAL New Stair w/ Railing – required if going to higher occupancy than 49 Required 2nd egress path if Assembly use exceeds 49 from the gathering space above the dance floor. A new accessible stair from the upper Assembly Space on the main level that is use for patron seating and potentially dancing. A structural Brace requires re-positioning. $750 - $1000 New Exterior Exit – required if going to higher occupancy than 49 Required 2nd egress exit out to the West if Assembly use exceeds 49. A new accessible stair and exit from or next to the platform would serve to split the exits from public use spaces. $3000 - $3500 Floor Repair – required to optional Required repair of the wood floors on the main levels to take care of trip hazards where planks have heaved or have major holes. $1000 - $2000
Optional to refinish floors (maintain a rustic appearance) but overall enhance the image of the facility and lengthen the maintenance life of the floors. $9000 Entrance – 250 sf, Dance Floor – 500 sf, Platform – 155 sf, Stair – 60 sf,
Mezzanine 1 – 760 sf.
Guardrail – required Openings in the guardrail above the main dance floor are not acceptable for public spaces for raised floors more than 30.” The top rail/ plank of the guardrail is rough and could be deemed unsafe. $1500 – $2500 Mezzanine 1 – 36 lf, Mezzanine 2 – 13 lf. Ramp #1 and Railing – required Access to the main dance floor from the entry foyer is currently accommodated by a ramp that does not meet current accessibility codes. The ramp should be rotated and extended to meet requirements and a railing will be required. Can be constructed of plywood and simple metal pipe railing. $900 - $1200 Ramp #2/ Sloped Floor – required At the mouth of the large barn door entrance there is a steep ramp which creates a trip/fall hazard and does not meet accessibility codes for an entrance. The recommendation is to color (paint) safety yellow or orange to denote the hazard. A 1:20 ramp is not feasible here. An additional exit on the West Side of the dance floor is required to avoid this area being required for exiting. The small floor brace shall also be painted. $300 Fire Extinguisher Cabinets – required Fire Extinguisher placement, housing (i.e. cabinets and/or hooks) and signage will need to be addressed based on occupancy and type. $800 Currently there are four fire extinguishers around the main areas of
congregation. Allowance for 8 total fire extinguishers. Signage – required Code required signage to include “posted occupancy,” “Do Not Enter,” Way-Finding for “Restrooms” (in other locations), and Electric operated Exit/ Egress Signage will be required for meeting code and gaining a certificate of occupancy. Emergency Egress lighting will be required and can be done so in combination with Exit Signs or separately to ensure path of egress is lit by battery backup in the instance of power failure.
Securing the Stairs to ensure “No Public Access” above and below the main assembly areas will be required. $1250 - $1500 Lighting Upgrade – optional The building is dimly lit. Depending on the use requirements and desired events it is recommended to add additional (permanent) lighting to storage and assembly areas appropriate to the functions of each space to provide more flexibility and longevity for the facility. $11,500 - $17,100 Electrical – required to optional Minimal increase in loads to get power up to the recommendations for better flexibility for running equipment and lighting interior and exterior of the barn are recommended. By code the service or sub panel may be required replacement to increase in size (load or amperage) but it is also expected that an upgrade is required just to run the minimum equipment foreseen in the main assembly areas in addition to lighting requirements and enhancements. Add 400 Amp Service, wiring and additional outlets. $6000 - $8000 Bracing [Head Knocker] Obstruction – required Column, overhead braces which extend to columns lower than 80” from the floor represents a head knocker condition. Reworking the column bracing is required; refer to structural for description. $750 - $1000 (3) overhead braces and two floor level (trip hazard) braces. Siding/ Windows/ Trim – optional Tightening up the building envelope is highly recommended. Replace or repair bad siding, seal up holes and major cracks, seal windows by adding trim and sealant. $500 - $3000 Hardware and Locks – required to optional Door hardware on accessible doors is required to meet codes for latch/ release, hinges, closers and types of locks. Currently there is just the main entrance that will require installing new hardware and potentially the sliding barn door; 7 openings. $3000 - $5000
Barn Door Operation – optional Currently the operation of the barn door is limited. The Door should be evaluated and corrected to more easily use. Repair of the door sliding mechanism, hardware, and cladding can be expected. $2500 - $5000 Fire Sprinkler – required to optional To comply with life safety codes for an occupancy higher than 100 with alcohol service, the facility would be required to have a fire sprinkler (Dry Pipe Type). The facility would need a large reserve water tank and pump to provide any system or require a new service line with booster pump to be installed. With no viable water source with enough pressure, having a fire sprinkler is not economically feasible. $80,270 - $82,570 (Tank System) $93,570 - $95,570 (New Water Line) COST ESTIMATING – STRUCTURAL Roof joists – required to optional The roof joists are deflecting significantly and the unbraced length is large. This is not an immediate repair, but for longevity additional support should be added. Additional joists can be added between existing to provide stiffness. $1000 - $5000 Floor joists – required to optional Several locations were identified that have cracked joists, missing support, or other minor damage. These minor repairs located throughout the structure should be done to ensure no further damage. $200 - $2000 Mezzanine Loft Storage – required The bottom of joists were planned and the support beam appears to have rotated and checked. This support beam must be monitored to confirm that additional rotation and signs of distress do not occur. $0
Attic Stair – required to optional The attic stair support does not track down to a main support. Additional framing should be placed under this stair if the space is intended to be used for storage. $200 - $500 Basement Columns – required to optional Due to the amount of moisture the basement typically sees and the discoloration of the posts in this area, it is recommended that the wood posts be checked on a regular basis for deterioration. A protective coating may also be beneficial for longevity of the structure. $0 - $500 Load Path Analysis – required to optional This report focused on visible observations and is provided as a summary of these findings. Due to the multiple additional to this barn, various levels and coverings, the load path for this barn is extremely complicated. If the district does decide to utilize the structure for groups greater than 49 persons and undertake renovations, these load paths should be confirmed. This will require a more extensive structural review of tracking all loads into the foundation. This will also be required if bracing (head knocker) obstruction must be moved. If a brace must be moved, the loading to each brace must be known to determine how much it can be moved, how it can be moved, and what needs to be replaced. $5000 - $10000
