1 Moonlight Architecture, Inc. Architecture Interior Design Site Planning 22 May Mr. Michael J. Petit de Mange, County Administrator Kent County Levy Court 555 Bay Road Dover, DE RE: Facilities Study & Evaluation for an Existing Structure to be converted to a New Emergency Medical Services Facility. Dear Mr. Petit de Mange; This study was performed for the Kent County Levy Court in order to determine the adaptability and structural stability of an existing structure for the conversion to a future Kent County EMS Facility to help service the western side of the district and reduce response time for the EMS service. The structure is approximately 1,800 square feet and is located west of town at 2490 Forest Avenue, Dover, Delaware. The building s original construction date is uncertain but is estimated to have been constructed over 40 years ago and has had several additions that have been added to the structure. The structure is a single story building made of multiple types of construction. The main part of the structure is constructed of CMU block walls with wood trusses. One of the later additions is constructed of the same CMU block and trusses while the other addition was constructed of conventional wood framing for the walls and the roof structure. The entire structure s floor system is constructed of concrete slab on grade, and it is assumed at this point until further investigation, that the footing system is a typical spread footing. The exterior finish of the building has an Exterior Insulation Finish System (EIFS) over the CMU block for most of the structure and the rear of the building, which is the later addition, has a vertical vinyl siding on wood sheathing. There are 2 large aluminum storefront windows and 2 aluminum storefront doors on the front and side of the building with a single flush metal door at the rear of the building. The roof of the building is a pitched roof with asphalt shingles over the entire roof.

2 The building plan consist of a large open retail area with walk-in coolers at the rear of the space, a bathroom which conforms to the ADA requirements and has a single toilet and sink, a Food Prep area, a Storage/Utility Room with a mop sink, and electrical and phone panels for the building. The interior finishes of the building are as follows. The walls have a painted drywalls with ceramic tile in the Food Prep area, and FRP in the Bathroom and Storage/Utility Room. The ceiling is a lay-in acoustical ceiling tile set into suspended metal grid for the entire building. Field Survey Findings: On May 16 th representatives from Moonlight Architecture and MacIntosh along with Mr. Petit de Mange, County Administrator, and Mr. Falkner, Director of Public Safety met at the Site to survey the existing conditions. After a careful survey of the existing structure the following issues were discovered along with our recommendations for a possible solution for repairing the issues: 1. Upon first arriving to the site we noticed that the structure and the site are almost at the same elevation and that there isn t a lot of slope to drain water away from the structure although there is some slope. In addition, there appears to be a negative slope at the single door at the front of the building causing water to drain back to the building and under the door into the building. The site grading needs to be reworked to allow for better drainage away from the building. 2. The overall exterior walls of the structure appears to be in good shape, and does not require any immediate action at this point in time, but there are some areas of concern if the County moves forward with this project. a. There is some patching of holes in the EIFS that needs to be patched around the structure. Over the main entry, where signage use to be, needs to be patched and to the left of the entry the EIFS is crushed and needs to be patched. b. At the east side of the structure, near the lower left corner of the window, the EIFS is detaching from the wall and needs to be secured. c. At the rear of the structure along the lower edge of the wall the wood framing appears to be soft and starting to deteriorate and, eventually, the wall will need to be replaced. This is due in part, possibly, from the grading around the structure which should be resolved with site work in the event the County moves forward with the purchase of the building. 3. The metal door at the rear of the structure leading to the storage room is rusting and warped and should be replaced. Most likely the door would be changed or the location reconfigured in the building renovations.

3 4. Moving to the interior, the structure appears to be in good shape with the exception of a leak in the ceiling over the large open area. In addition, the roof sheathing at the area of water infiltration is deteriorating and covered with mold. We were unable to determine at this time whether the roof trusses have any significant water damage to the top chords and whether they can be fixed or if they need to be replaced. In any event, it would not be a major task to repair this item. The roof sheathing in this area should be removed and replaced with new sheathing. 5. There is some insect infestation of some sort along the window sill of the front window of the structure. It is our recommendation that a Termite Inspection be done on the entire structure to verify the type of infestation and to determine whether the insect problem extends beyond the front window sill of the structure or if it is an isolated condition. 6. Last, although the existing floor is a slab on grade and is in good shape there are a number of differential floor heights and uneven spots in the structure. This can be resolved by applying a new thin coat of concrete or leveling compound over the existing concrete slab. If the County decides to move forward with the purchase and renovations of this building it is our recommendation that they remove the EIFS and vinyl siding from the entire structure and in the design process install a new and alternate type of finish for the exterior of the building. In addition, the entire roof finish of the structure should be removed and replaced with a new roof finish along with replacement of the deteriorated roof sheathing. We have included a copy of a MacIntosh Engineers findings for additional information regarding the structural stability of the structure along with their recommendation for resolving any issue mentioned in their report. With respect to the adaptability of the existing structure for the intended use as an EMS facility we offer this information. The existing structure, consisting of trusses and exterior bearing walls, is constructed in a manner which allows for a large open area inside of the exterior bearing walls allowing a lot of flexibility in the interior room layout. There is a large steel beam over the existing window opening at the front of the structure which would allow for Garage doors to be installed at the front of the building without having to modify the structure at all. The EMS facility has a requirement for a Garage with exhaust system to house 2 EMS vehicles, an Office, 2 Bathrooms with space for showers and lockers, a Bunk Room to sleep up to 4 people, Lounge area, lockable Storage Room, Utility Room, a small Decontamination Room, a possible Conference Room for up to 8 people, and a possible area for a Public Walk-in Clinic. This program would constitute approximately 2,000 to 2,200 square feet of area to fit the program. Based on the program for the EMS facility and the fact that the existing structure is Moonlight Architecture, Inc Lewes-Georgetown Highway Lewes Delaware DE (302) MD (410) Fax (302) moonlightarch.com

4 only approximately 1,800 square foot we feel that it would be difficult to fit the proposed EMS program into the existing footprint of the structure. But, if the County were to put an addition on the existing structure, provided the site could support the additional square footage of the structure, the existing structure would be suitable for the proposed intended use as an EMS facility. In conclusion, based on our field survey and examination of the existing structure, it is our recommendation that the existing structure located at 2490 Forest Avenue, Dover, Delaware is structurally sound for future habitation and is suitable and adaptable for the future use as an EMS facility.

5 MEMORANDUM TO: FREDDY BADA FROM: MARK NAUMAN SUBJECT: 2490 FOREST AVENUE SURVEY DATE: MAY 17, 2018 CLIENT#: As per your request, we visited the above referenced site on the morning of Wednesday, May 16, 2018 to observe the existing building and assess the condition of the existing structural elements. The existing single story building is constructed of wood roof trusses bearing on CMU walls in the front with wood rafters bearing on wood walls. The whole building has a concrete slab on grade. The existing CMU walls and concrete slab appear to be in good condition. There are some minor, non-structural cracks in the slab and walls. There are some areas of uneven slab surfaces that could be addressed with a top skim coat. The existing wood trusses and wood rafters appear to be in generally good condition. There are two items in the wood framing that should be addressed: 1) There is a large area of water damage at the high truss roof level. It appears that the water damage extends only through the roof sheathing and does not affect the truss members below. If so, the wood roof sheathing at this area would need to be replaced but all trusses could remain. 2) The wood bearing walls at the rear of the building were covered and could not be fully assessed. They appear to be bearing at a low elevation close to the top of slab and top of exterior grade. If so, these walls should be evaluated for any moisture or insect damage prior to completing any renovations. If you have any questions or concerns, please don t hesitate to contact our office.
