Hillsborough Elementary Mebane 336-227-2031 Renovation Capital Project Ordinance PURPOSE: To approve a capital project ordinance for Hillsborough Elementary School renovations. BACKGROUND: Hillsborough Elementary School is the only year-round school in Orange County. The campus, originally constructed and developed during a ten-year timeframe from 1952 to 1962, consists of six freestanding buildings interconnected by covered walkways. Over the years, the campus has served as a high school, a middle school, and now an elementary school. The most recent renovations were completed in 1996 when the OCS Board of Education elected to offer a year-round elementary program to students and parents. Attachment 1 of this abstract outlines a basic map of the Hillsborough Elementary Campus. During the Capital Needs Advisory Task Force process in spring 2001, the Orange County Board of Education identified Hillsborough Elementary renovations as one of its top priorities for the November 2001 bond referendum. As originally presented to the Capital Needs Advisory Task Force, this project involved constructing an addition'to the Board of Education Building located on Cameron Street in Hillsborough. The additional space would allow the relocation of Central Office staff who were housed in the 300 Building at the Hillsborough Elementary Campus to the Board of Education Building. The vacated space in the 300 building would then be reconfigured and renovated to provide additional classroom space for Hillsborough Elementary. The total projected cost of that particular scenario was in the neighborhood of $3 million. The Board of Education identified funding sources for the project as 2001 bond funds, alternative financing such as a private placement loan and School Construction Impact Fees. It is important to note that the focus of this project has changed since it was first presented to the Capital Needs Advisory Task Force in spring 2001. Since the original proposal in spring 2 2001, the Board of Education has reassessed its need fo create additional space at the Central Office located on Cameron Street in HHlsborough. As an alternative, the Board of Education has identified other temporary office spaces at existing schools to relocate the Central Office staff, thereby postponing the immediate need to construct additional office space for administrative staff. The solution includes relocating.the staff to space at Orange High School, Cedar Ridge High School, and mobile units at Cameron Park Elementary School and the Board of Education building on Cameron Street. This reassignment solution is only temporary because as student membership increases, the space being used by central office staff will need to be reclaimed for classroom space. The immediate result in cost savings by postponing this construction is $1.650 million. On September 3, 2002, the Commissioners reviewed a proposed six-year plan for issuing 2001 Bonds and Alternative Financing that would allow for the temporary reassignment of Central Office staff outlined above while immediately addressing needs at Hillsborough Elementary in fiscal year 2002-03. The proposal also outlined that the County would issue alternative financing, for $1.650 million, in fiscal year 2004-05 to address space needs for Central Office Staff. This alternative would allow the Board of Education to proceed with plans to increase the square footage of the current square footage of the Board of Education building located on Cameron Street in Hillsborough. In August 2002, the Orange County Board of Education awarded a professional services contract to the architect firm of Corley, Redfoot, Zack, Inc. regarding the planned renovations. The contract calls for architectural, engineering and design services as well as construction management services from the firm. Attachment 2 of this abstract is a preliminary report from Corley, Redfoot, Zack, Inc. regarding Hillsborough Elementary School. In summary, the potential renovations for the school could include:, • Addition of six new classrooms to increase capacity by 100 students • Correct mold, mildew and air quality problems • Renovate and upgrade restroom facilities ' • Replace floor covering with an "earth friendly"the floor system • Install new doors, door hardware and lighting, as needed • Upgrade electrical system, as needed • Repaint interior walls • Addition of gutters and downspouts and roof repairs, as needed In accordance with the Board of Commissioners Policy on School Planning and Funding School Capital Projects, renovations at Hillsborough Elementary School, is a Level 1 project — one that involves a relatively small scope of work -- thereby allowing the Commissioners to approve the entire project ordinance at one time. The recently approved contract with Corley, Redfoot, and Zack, Inc. totaled $1.440 million. The breakdown of the contract is outlined in the following table: 3 Architect/Engirneering Design Fees (Including Testing, Surveying and Reimbursables) $125,000 Building and Site Construction $1,271,800 Project Contingency (3% of total budget) $43,200 Total Proposed Budget $1,440,000 FINANCIAL IMPACT: Funding sources identified for the renovation project includes 2001 voter approved bond funds ($900,000) and School Construction Impact Fees ($540,000). Upon completion of the project, staff will bring back a final accounting that will outline how actual expenditures relate to the budget: RECOMMENDATION (S): The Manager recommends that the Board approve the Hillsborough Elementary School Renovations Capital Project Ordinance. 500 Building (Gymitorium) c a� E 300 Building cc� (Renovation <t 400 Building (Leased to Private plans include 6 Pre-School New Classrooms Program) for 100 students} a 600 Building Covered Walkway Cafeteria MD 0 � U m 100 Building o 200 Building (Classrooms, U (Classrooms) Media Center, Covered Walkway School Office Staff) Hillsborough Elementary Campus Map Not drawn to scale A44dc.hrneni- 2 5 Corley Redfoot Zack, Inc. Preliminary Report on Existing Facilities Thursday, July 25,2002 Page 1 School: Hillsborough Eementary School Location: Hillsborough,North Carolina Owner: Orange County Schools Hillsborough Elementary School(HM)has served the citizens of Orange County well for over 50 years, first as a high school,next as a middle school and currently as an elementary school. It has reached a point in its useful life when:some major modernizations,upgrades,repairs aad proamm enhancements are in order. The purpose of this report is to provide preliminary,investigative information regarding the existing facilities to assist in determining the scope of the renovations to be performed. HES is an open campus of six freestanding buildings interconnected by a network of covered walkways. The 100 Building and 200 Building are basic classroom buildings. The 300 Building was designed as a classroom building,but is currently used as office space by the Orange County School's Support Services Department. The 400 Building(previous Shop Building) is currently leased to a:private organization that runs a private pre-school program on the campus. The Soo Building consists of a Gymitorium (combination gymnasium and auditorium), and associated spaces that are currently housing the art classroom, academically-gifted program and faculty offices. The 600 Building houses the Cafeteria. All six buildings were constructed between 1952 and 1962,a time period when quickly built, inexpensive school facilities were the rule due to the expanding student populations after WWII. Some of the general characteristics of construction from that period of time include light structural frames, little(if any) thermal insulation, and simple heating and ventilation systems with no provision for air conditioning. The 100 Building opened in 1962. It was built to replace an existing building that bumed. A portion of the original building(the boiler room)was retained and became the boiler room for thw current building. The 100 Building exhibits the following features: . • A two-story,concrete structural frame including concrete floor and roof structure., • An exterior wall consisting of a 10°thick infill and aluminum windows that span between exposed concrete columns and beams. The walls are made up of a 4"concrete masonry unit, a 2" air space and a 4"exterior brick. The original windows were replaced in about 1990 with a thermally unbroken aluminum window system. During site investigation,it was noted that the weepholes (holes that allow the air cavity to release water) in the exterior walls were small holes (about the diameter of a pencil)and could be clogged easily. • A roof that has reached its useful life and needs to be replaced. The single-ply membrane roof was replaced in 1987(15 years old). Many small blemishes are forming due to its age that could create small leaks in the future. The original roof deck was truly flat with internal 6 Hillsborough Elementary School Renovations •7/25/2002 Preliminary Report on Existing Facilities Page 2 E drainage. Tapered insulation and large,galvanized steel gutters were added during the reroofing to provide minimal slope and to collect the rainwater and divert it to the grade. According to The Garland Co..,a roofing consultant that assessed the condition of the roof earlier this year, the existing single-ply roofing membrane and the roof insulation needs to be replaced and the perimeter flashing needs major repairs. • An interior that has not changed significantly in 40 years. Metal lockers line the corridors. Some of the existing home economics cabinetry is still in use. • A building program that includes classroom space.for grade two through five, the school's media center, the school's administrative offices and the data distribution room. The building serves the program adequately,but does not meet NCDPI guidelines for school construction. A computer lab located near the media center works well,and a campus television studio which is prized by school staff. • Interior partitions that are primarily 8"concrete masonry. The doors and door frames are predominately original. The floors are mostly vinyl composition tile(some placed over vinyl asbestos tile) in corridors and storage rooms and carpet in the classrooms, offices and media center. An elevator with a first floor machine room was added in 1990. • Odors emanate from various rooms around the building. More than likely,these smells are caused by water penetration from the roof,walls, windows or other source,and mold. • A lack of ventilation. When the air conditioning was provided.in 1990,no ventilation vents were created for the unit ventilators in the classrooms or offices. The HVAC system consists of a two-pipe heating system and a two-pipe cooling system that feeds unit ventilators located on the floor in each room The boiler is located in the old boiler room. • A rodent problem. Rodents from the boiler room travel along the pipe chase along the north side of the First floor. The 200 Building opened in 1952. The 200 Building exhibits the following features: • A one-story, lightweight,structural steel flame with a concrete slab floor and a"Cemesto Insulation Roof Deck". • An exterior wall consisting of 12"thick masonry end walls,8 W'thick masonry walls below window sills and aluminum windows that extend the length of the building. The walls at the ends of the building are made up of a 8"concrete masonry unit and a 4"exterior brick and, the walls under the sills are made up of a 4r concrete masonry unit,a rh"air space and a 4" exterior brick. The original windows were replaced in about 1990 with an aluminum window system that allows heat to transfer through the window frames. During site investigation, it was noted that the weepholes(holes that allow the air cavity to release water) i.. .he Lxtrerior walls were small holes(about the diameter of a pencil) and could beclogged easily. •, A rooPthat has reached its useful life and needs to be replaced. A four-ply,coal tar built-up roof that was replaced in 1984(18 years old). The origins!roof deck was truly flat and has no gutters or other internal drains,so the rainwater drains off the edge of the roof onto the ground. According to The Garland Co.,a roofing consultant that assessed the condition of the roof earlier this year,the existing built-up roofing and the roof insulation needs to be replaced and the perimeter flashing needs minor repairs. According to the consultant's report,there are two roof layers that must be removed prior to reroofing of the building.

Acoustical tile ceilings anc r,Pr:c wire installed in all the classrooms. Cabinetry is inconsistent through the building. A data closet was introduced onto the corridor cutting into one of the larger classrooms. • A building program that includes classroom space for kindergarten and first grades, the school's music classroom,and a Reading Recovery room. Two of the three kindergarten classrooms are adequately sized. One of the three kindergarten classrooms and all three first grade classrooms are very small and do not meet NCDPI guidelines for primary classrooms. • Interior partitions that are primarily 4"concrete masonry. The doors and door frames are predominately original. The floors are mostly viayl composition file(some placed over vinyl asbestos tile)in corridors,and a mix of carpet and vinyl composition tile in the classrooms. Quarry tile is used in the group toilet rooms. • Odors emanate from various rooms around the building. More than likely,these smells are caused by water penetration from the walls, windows or other source,and mold. • A lack of ventilation. When the air conditioning was provided in 1990,no ventilation vents were created for the unit ventilators in the classrooms. The HVAC system consists of a two- pipe,hot water heating system that emanates from the boiler room located below the cafeteria. Insulated and jacketed hearing pipes,that replaced the ruptured,underground steam pipes in 1997,travel across the existing covered walkways and enter the building on the west end of the building. The cold water cooling system begins in the cooling tower located north of the building, is pumped from a mechanical room in the 300 building and circulates through unit ventilators located on the floor of each classroom The 300 Building opened in 1959. The original floor plan appears to have been designed for primary classrooms. The Orange County School's Support Services Department is currently using the building for office and storage space. The 300 Building exhibits the following features: • A one-story, lightweight,structural steel forme with a concrete slab floor and a "Camesto Insulation Roof Deck". • An exterior wall consisting of 12"thick masonry end walls, 8 W thick masonry walls below window sills and aluminum windows that extend the length of the building. The walls at the ends of the building are made up of a 8"concrete masonry unit and a 4"exterior brick and the windows under the sills are made up of a 4"concrete masonry unit,a W' air space and a 4"exterior brick. The original windows were replaced in about 1990 with a thermally unbroken aluminum window system. During site investigation,it was noted that the weepholes(holes that allow the air cavity to release water)in the exterior walls were small holes(about the diameter of a pencil)and could be clogged easily. • A roof that is serviceable. It appears to be a modified bitumen roof with a granular cap sheet, and according to school system records, it was replaced in 1994(8 years old). The original roof deck was truly flat and has no gutters or other internal drains, so the rainwater drains off the edge of the roof onto the ground • An interior that has been renovated piecemeal over the past 12 years ago.

Insulated and jacketed steam heating pipes,that replaced ruptured,underground steam pipes in 1997,travel across the existing covered walkways and enter the building on the south end of the building, Air conditioning is provided by individual window air conditioning units. The cooling tower (mentioned above)appears to be sized to provide air conditioning to the 300 Building in the future. The Cafeteria Building opened in 1952. The Cafeteria Building exhibits the following features: • A one-story, lightweight,structural steel frame with a concrete slab floor and a"Cemesto Insulation Roof Deck". • An exterior wall consisting of 12"thick masonry walls and aluminum windows. The walls are made up of an 8"concrete masonry unit and a 4"exterior brick. The original windows were replaced in about 1990 with a thermally unbroken aluminum window system. • A roof that has reached its useful life and needs to be replaced.

According to The Garland Co.,a roofing consultant that assessed the condition of the roof earlier this year,the existing single-ply roofing membrane and the roof insulation needs m be replaced and the periineter flashing needs major repairs. • Floors that are mostly vinyl composition file(some placed over vinyl asbestos tile) in the dining area,and quarry the in the kitchen. • A heating system consisting of unit heaters located near the ceiling and an cooling system consisting of(2)floor-mounted package air conditioning units. The Gymnasium Building opened in 1959. The Gymnasium Building exhibits the following features: • Two separate structural systems. The gymnasium area is a steel,long-span structural system with steel trusses and purlins. The locker area is a one-story,poured-in-place concrete structure. • An exterior wall consisting of 12"to 16"thick masonry walls with original metal windows. • A roof that is serviceable. It appears the curved gymnasium roof is a modified bitumen roof with a granular cap sheet(similar to 300 Building), and according id'school system records, it was replaced in 1988(14 years old). The flat,locker area roof appears to be a four-ply built- up roof,and according to school system records,was replaced in 2001..During site investigation, ponding water was noted on the locker area roof. • Finishes are all original. The wood flooring in the gymnasium and stage area is maple flooring and has been renovated recently. The lobby,toilet rooms,offices and locker areas are all in original condition. • A building program that includes physical education, art,and miscellaneous (919) 1.)42-8586 Telephone R051602existingfacilities.doc (919)929-4802 Fax 9 Hillsborough Elementary School Renovations -7/25/2002 Preliminary Report on Existing Facilities Page 5 • A heating system consisting of a two-pipe,hot water heating with a boiler room located to the West. A cooling system consisting of a two-pipe loop with a cooling tower and air handling units. The locker area cooling system consists of(2) through-the-wall air conditioning units. Following is a list of potential renovations to each building: Building 100 • Add group,toilets on the first floor of the building. This would require changes to the Floor that could affect some of the classrooms or office space located there. • Address the mold and mildew problems. • Remove all unit ventilators for thorough cleaning and maintenance • Provide new exterior vents in exterior brick wall for all unit ventilators and rework unit ventilators to provide fresh air into the classrooms. • Remove all carpet from the classrooms as this may be a significant habitat for mold. Removing the carpet and vinyl composition the may require asbestos abatement of the existing vinyl asbestos tile. Install earth-friendly floor tile system similar to other installations in the school district. 6 Reroof the building including new insulation and edge flashing • Rework the exterior drainage system to insure rainwater is being drained away from the building. • Provide new standardized casework in all classrooms with an emphasis on storage of classroom materials. • Determine whether new lighting fixtures are wan-anted. Verify the condition of acoustical ceilings and replace as necessary. • Provide new doors and door hardware into each room. Try to reuse the existing door frames. • Address the rodent problem by permanently sealing all penetrations from the boiler room into the building. • Address the heat build-up in the south-facing classrooms by providing perforated window shades so the heat is abated,but the view is not totally blocked. • Repaint the entire building on the interior. • Dete*ne if any electrical upgrades are required or desired by the school. t Building 200 • In the final build-out,the classrooms may need to reconfigured to morn closely meet NCDPI guidelines for primary grade classrooms. In order to achieve this,three of the classrooms may need to be merged into two larger classrooms. • Renovate the group toilet facilities.

Relocae the existing data closet so that it does not impact academic areas. Building 300 • This building requires major renovations in order to transform it from its current use as office space to classroom space for elementary education. Depending on the final programmatic requirements agreed to,all rooms will probably need to be completely renovated including, but not limited to,flooring,ceilings,lighting fixtures, markerboards,tackboards,casework. • Whether the group toilet facilities will need to be renovated is up to the final program. • The beating and cooling systems will need to be upgraded. The Beating system should be rewo`rked to use hot water in lieu of the current steam system. This would require running new piping from the existing boiler room under the Cafeteria or creating a separate small boiler for this building. By replacing the steam beat with hot water, the condensate lines that run throughout the building may be abandoned. A new cooling system should be provided utilizing the existing cooling tower located to the west of the building and the pumps located adjacent to the girls' toilet. A new HVAC system could be designed that would accommodate both heating and cooling functions in one air handling unit.
