Porcupine Mountains Wilderness State Park

Scope of work for historic service area building renovations

October 8, 2020

NOTE REGARDING PRIORITIES: Priorities are listed in order for each building. Buildings are also listed in order by priority.

I. The following buildings are the National Register of Historic Places: Staff quarters and Lodge

II. Staff quarters (AKA bunkhouse/triplex):

1. Provide plans for LARA plan review, if necessary/required.

2. Roof related.

a. Provide analysis which investigates the installation and ventilation of the Staff Quarters attic space. The investigation should consider volumes and material types of existing insulating materials, the presence of hazardous materials, and the effectiveness of existing ventilation. Recommendations should consider the project budget in finding solutions to ensuring improved insulation and ventilation associated with the proposed roofing systems.

b. Replacement of asphalt shingle roofing system. Design of system is to require enhanced installation requirements to provide high wind warranty.

c. Repoint and re-flash chimneys as needed (2).

d. Provide chimney cricket to north chimney.

e. Replace flashings for through roof vent pipes.

f. Repair / replace fascia where required.

g. Replace drip edge and all flashings.

h. Repair / replace sidewall siding where roof interacts with siding.

i. Minor quantities of sheathing replacement and rafter repair are anticipated around the north chimney.

j. Replace gutters with commercial gutters.

3. Repair foundation (concrete masonry unit) in NW corner of building (west wall of northern most basement)

a. Remove 10 courses of block x 22’ 9 ½” in length.

b. Utility relocations or remove and replace may be required for the following utilities:

i. Remove and replace supply plumbing.

ii. Remove and replace waste plumbing.

iii. Remove and replace electrical wiring.

iv. Furnace duct work may require removal and replacement.

c. Replace 1 basement window: Measures 2’ 8 ½” x 14 ¼”.

d. Provide temporary shoring recommendations.

4. Perform hazardous materials survey (and per PSC recommendations abatement).

5. Upgrade / replace electrical system in building

a. Review service panel and 3 sub-panels (1 sub-panel for each the north, middle, and south unit). Ensure that main service panel and sub-panel are adequately sized and are properly grounded.

b. Review conductors in all units and on all floors (Attic, 2nd floor, 1st floor, and basement).

There are many circuits that have 2 prong receptacles with no ground and/or have 3 prong receptacles with an open ground. There are some (limited) circuits with 3 prong receptacles where a ground wire is present. The PSC is to recommend replacement or modification to existing conductors.

c. Review receptacles

i. Ensure GFI or ARC fault receptacles are installed where needed.

ii. Ensure receptacles with grounding is present where needed.

iii. Work with DNR to identify where additional receptacles are needed or could be easily placed (both interior, exterior, and basement).

d. Review appliance(s) supply wiring.

iv. Stove, Refrigerator, water heater, furnace/boiler, washer, dryer, etc – in all 3 units.

e. Address any additional electrical hazards or non-code compliant issues identified (connections, j-boxes, overloaded circuits, grounding, etc.).

6. Plumbing

a. Supply plumbing

a. Provide supply plumbing to the following elements in the south unit:

i. Water heater

ii. Basement boiler

iii. 2nd floor boiler

iv. Kitchen sink

v. Downstairs bathroom (sink, shower, toilet)

vi. Upstairs shower

b. Replace all galvanized supply plumbing.

c. Retain all copper supply plumbing unless discovered by PSC to be undersized.

d. Provide shut offs to isolate fixtures for maintenance and repair.

e. Provide blow offs for winterization.

b. Waste plumbing

a. Replace all galvanized waste plumbing in North, Middle, and south unit.

b. Provide new waste plumbing to south unit (sink, shower, and toilet).

7. Mechanical:

a. North Unit:

a. Replace water heater

b. Replace furnace

b. South unit

a. Design hook up of boilers both upstairs (2nd floor) and basement.

b. Specify replacement water heater that is compatible with boiler.

8. Provide Phase 100 analysis with investigating ADA accessibility to the Middle and South Unit. Review existing floor plans and structural details for determining if these two units can efficiently be combined to allow for 1st floor level accessibility to a studio apartment style dormitory offering accessible living quarters including bathroom facilities. A conceptual floor plans shall be developed by the PSC as part of the Phase 100 analysis. Floor plan, structural, plumbing, mechanical, and electrical review is required to determine concept options and feasibility.

III. Lodge:

1. Provide plans for LARA plan review, if necessary / required.

2. Roof related

a. Provide analysis which investigates the installation and ventilation of the Lodge’s attic space. The investigation should consider volumes and material types of existing insulating materials, the presence of hazardous materials, and the effectiveness of existing ventilation. Recommendations should consider the project budget in finding solutions to ensuring improved insulation and ventilation associated with the proposed roofing systems

b. Replacement of asphalt shingle roofing system. Design of system is to require enhanced installation requirements to provide high wind warranty.

c. Repoint (as required) and re-flash chimney (1).

d. Repair chimney flue and replace missing cap.

e. Replace flashings for through roof vent pipes.

f. Repair / replace fascia where required.

g. Replace drip edge and all flashings.

h. Repair / replace sidewall siding where roof interacts with siding.

i. Replace gutters with commercial gutters.

3. Perform hazardous materials survey (and per PSC recommendations abatement).

4. Upgrade / replace electrical system in building

a. Review service panel and service panel grounding for adequacy.

b. Review circuits for loading and design electrical system to properly meet demand and code requirements.

c. Review conductors (existing is 2 prong with no ground), recommend replacement or modification to existing conductors.

d. Review receptacles

i. Ensure GFI or ARC fault receptacles are installed where needed.

ii. Ensure receptacles with grounding is present where needed.

iii. Work with DNR to identify where additional receptacles are needed or could be easily placed (both interior, exterior, and basement).

e. Review appliance(s) supply wiring.

f. Address any additional electrical hazards or non-code compliant issues identified

(connections, j-boxes, grounding, etc.).

5. Plumbing

b. Waste plumbing

a. Replace all galvanized waste plumbing in North, Middle, and south unit.

b. Provide new waste plumbing to south unit (sink, shower, and toilet).

6. Replace boiler.

Fire barn (AKA equipment storage shed):

1. Phase 100 analysis: Review foundation failure, conceptualize and cost estimate potential repairs. Conceptual review of the Fire Barn’s footing to determine the limits of the footing’s deterioration. The conceptual analysis may include phased excavations to determine the extent of the footing failure and feasibility of repair or reconstruction. Should footing repair or replacement be determined feasible – conceptual (Phase 100) plans, details, and cost estimates are required.
