13.1 EDUCATIONAL PROGRAM ASSESSMENT

Gilbert Architects Inc. (GAI) conducted an educational program assessment of Wilde Lake High School during the months of August and September, 2007. This included an interview with Restia Whitaker, Principal, and Tammy Foyles, Assistant Principal, on August 15, 2007 (copies of minutes are included in Section 13.7); a survey of the existing building on August 24, 2007 utilizing the Council of Educational Facility Planners International (CEFPI) Guide for School Facility Appraisal for High Schools; and a review of original design and existing floor plans to compare program utilization with the current High School Educational Specifications for HCPSS. This building has a total net program area of 155,231 sf versus the educational specification standard of 171,841 sf, or a net deficiency of -16,610 sf (9.7%). There are a few programs that are oversized in this building, including student support (+288 sf), CR&D (+297 sf), and auditorium (+2,468 sf). The space allocated to the auditorium includes the mini-theater (+2,920 sf) that was built as a joint venture with the Howard County Arts Council. Several programs are undersized, some significantly, including art (-1,561 sf), tech. ed. (-1,091 sf), mathematics (-2,965 sf) and social studies (-2,637 sf). It is estimated that a building addition of between 27,000 and 33,000 gsf would be required to increase the size of all program areas to meet current ed. specs. It should be noted that the amount of space not dedicated to ed. spec. program at this school is greater (on a percentage basis) than any other Howard County Public High School (37%). It should also be noted that this school does not currently provide a regional program for JROTC or a regional program for Special Ed. Emotional Disturbances. If these programs are not added to Wilde Lake High School, the estimated gross sf of required building additions listed above could be reduced by approximately 5,000 gsf.

Wilde Lake High School had an enrollment of 1,376 students at the time of our survey with 72 total teaching stations. Four of these teaching stations were originally intended to be used as technical resource rooms. Enrollment projections indicate decreases at this school for the next several years.

Overall, Wilde Lake High School received a score of 833 points out of 1,000 on the CEFPI Appraisal Guide, equating to a “good” rating. This is an indication that there are areas of improvement that could be implemented to raise the score to a high “good” or “excellent”. A copy of the detailed CEFPI assessment is included in Section 13.3.

The manner in which spaces are actually being utilized may vary from the original design based on the discretion of the school’s administrators.

Building Program Variances

Based on the space requirements identified on the Educational Specification Comparison Chart following this section of the report, original design drawings and on our interviews and field surveys, we have identified the following primary building program variances at Wilde Lake High School (Note: variances less than 5% will not be discussed here – all data is available on a summary chart on pages 13.1-4 thru 13.1-7):

Administration is undersized by -401 sf (12.4%) and is missing a 4th_{assistant principal’s}

office. A security vestibule should be provided with control by the administration reception area.

April, 2008 Site Variances

Based on the site requirements identified on the Educational Specification Comparison Chart following this report, and on our interviews and field surveys, we have identified the following primary site variances at Wilde Lake High School:

Wilde Lake High School is located on a site of 31.3 acres. The minimum size

recommended for a high school is 30 acres plus 1 acre for each 100 students, or 43 acres. Preferred acreage is 53. Wilde Lake lacks nearly 22 acres to meet ed. spec. requirements.

There is a distinction between bus and parent drop-off/pick-up sites, however, parents drop off their students on the main road to avoid pulling into the parent drop-off area. Students then need to walk through bus traffic and parking areas to reach the building.

There is parking for 370 cars, 150 less than program.

The stadium turf is in fair condition. All fields are heavily used by the community causing additional wear. The all weather track was resurfaced recently and is in good condition. There are 6 lanes, 4 less than called for in the ed. spec. Bleachers and concession are in very good condition. Concession stand is original to the first school at this site (1971) and is in need of updating. Home bleacher capacity is approximately 1,500 seats (not ADA accessible) versus ed. spec. capacity of 1,500. Visitor capacity is approximately 500 seats (not ADA accessible) versus ed. spec. capacity of 1,000. There are permanent restrooms at in the stadium area.

Ed. spec. calls for two multi-purpose play fields and this school has one. Two football practice fields are required and there are none.

There are no exterior basketball courts.

There is one baseball fields compared to two required by program.

There are no softball fields at the high school versus the three programmed in the ed. spec.

There is no hockey field as required.

There is no fitness path running around the perimeter of the site. No outdoor amphitheater with stage.

13.4.3 Structural Summary

The structural system(s) for the building consisted of concrete footings and piers with structural steel columns and concrete masonry block (CMU) walls. Floors are concrete slabs on grade.

No structural deficiencies were noted involving foundations or structural members.

13.4.4 Exterior Elements Summary

Exterior walls: The exterior walls of the school generally consisted of brick masonry façade. The brick masonry appeared to be in good condition with only minor areas of damage or deterioration. The damage and deterioration consisted of broken and missing bricks and loose mortar at various locations throughout the walls. The mechanical penthouse walls were enclosed with an EIFS system. The EIFS wall generally appeared to be in good condition. Minor areas of damage were observed at various locations throughout the wall. The finish coat on the EIFS was in good condition, but faded and stained. According to on-site personnel the front portion of the EIFS walls was recoated this year.

Vertical masonry sealant joints observed throughout the building exterior were generally in fair to poor condition. The sealant joints were starting to exhibit signs of surface cracking and deterioration. Some separation of the sealant from the masonry

(25)

April, 2008

interfaces was also observed at various locations throughout the building exterior. At a few locations on the east side of the building (roof level) it appeared that the sealant had never been install in the joints.

Exterior windows: Windows at the building generally consisted of aluminum frame thermal pane unit and storefronts. The window style varied throughout the building. Most windows units had an operable top hinged dual light with four fixed lights. Sealants associated with the window units appeared to be in poor conditions. The sealant joints were exhibiting signs of surface cracking and deterioration.

Exterior doors: Exterior doors at storefronts were metal with glass windows. Other doors were insulated, painted metal doors in metal frames. Doors were observed to be in good condition, and should be painted on the regular painting schedule.

Exterior walls: Masonry tuck-pointing in 2008 (4,000 SF).

Exterior walls: Replace the exterior flexible sealants, including all building sealants in 2008 (2,750 LF).

Exterior windows: Replace sealant at the exterior windows in 2008 (1,750 LF). Exterior painting: Repaint exterior metal in 2008 and then on a 6 year cycle.

Exterior wall: Recoat EIFS walls starting in 2010 (15,500 SF). Minor repairs to EIFS should be performed prior to or during recoating (10 SF).

Masonry sealants: Continue replacement of masonry and window sealants on a ten year cycle.

13.4.5 Roof System Summary

The roof system primarily consisted of a low-sloped fully gravel surfaced built-up roof system. The flashing consisted of granular surfaced modified bitumen roof membrane. The built-up roof membrane appeared to generally be in good condition with only minor defects in the form of wind scour and exposed felts. The flashings were generally in good condition with some minor surface deterioration. Drainage was provided by interior roof drains. Roof access was provide by roof hatches and by wall mounted ladders for access to the remaining roof sections. The following issues were observed:

Built-up roofing (BUR) sections: The built-up roof membrane appeared to generally be in good condition with only minor defects in the form of wind scour and exposed felts. The flashings were generally in good condition with some minor amounts of surface deterioration. The remaining useful life for this roof is expected to be approximately 14 years if well maintained. The modified bitumen flashings, although generally in good condition, should be coated with an aluminized coating to prolong their service life.

(26)

April, 2008

Replace sealants: Replace in 2008 and every five years through the life of the roof system.

Aluminized coating to modified bitumen flashing: Apply in 2008 (1,750 Square Feet (SF). Reapply every five years through the life of the roof system.

Built-up roof membrane repairs: Replace in 2009 (500 Square Feet (SF).

Built-up roof membrane: Replace in 2021 (138,000 Square Feet (SF).

13.4.6 Mechanical Systems Summary

Description

The facility had a central chilled/hot water plant that included two screw compressor water chillers having approximately 260 tons cooling capacity each, a cooling tower, five gas-fired sectional cast-iron boilers having a total heating capacity of 13,565,000 Btu/hr. and 13 pumps ranging in size from 1½-hp to 60-hp that provided the cooling and heating water for the 13 variable-air-volume (VAV) and constant-volume penthouse air handling units all of which having return-air fans typically integrated in a return-air fan section with the exception of AHU no. 2 (Auditorium) that had an external duct-mounted in-line return-air fan.

Heating water only was also provided to the two heating and ventilation units, approximately 14 unit heaters, and 136 reheat coils (all but four of which are integrated in VAV terminal boxes). Gas-fired heating was provided by three packaged rooftop heating and ventilation units, one of which provided heated exhaust make-up air for the kitchen. Direct expansion (DX) only cooling was provided by eight split-system ductless air conditioners. We noted 72 various exhaust fans that provided general building and fume-hood exhaust and were located throughout the building roof. Building system controls were typically pneumatic relay-logic controls through automatic temperature control (ATC) panels that were integrated into a building automation system based on the Johnson Controls Metasys control components. Packaged equipment had integral electronic automatic temperature control systems.

A duplex 7½-hp tank-mounted compressor and Hankinson Dryer provided main air for the automatic temperature controls.

Condition

It was generally observed that the mechanical systems in the building appeared well maintained with observable evidence of ongoing maintenance with replacement components noted such as motor-operated control valves and damper actuators, lubricated shaft bearings, clean air filters, clean heat-transfer coils, and a general overall appearance of diligence. The range of condition seemed due mostly to age and equipment appearance ranging from fair to good except for the cooling tower catwalk steel supports. The catwalk

(27)

April, 2008

supporting steel had severe rust corrosion and was overdue for refinishing. The three-way condensing water diverter valve was being replaced and the cooling tower water filter was partially disassembled during a repair effort.

All of the equipment dates back to the 1996 original construction except for the cooling tower that was a replacement installed in 2007. The original cooling tower, reported to be a BAC Ejector tower, had to be replaced due to premature failure because of deterioration of the high-pressure spray system. We noted that the cooling tower drain line was not routed out to a roof drain, and that the overflow outlet discharged directly onto the roof membrane causing premature deterioration of the roofing material.

There were reported issues regarding the HVAC systems in terms of comfort and perceived cooling capacity especially in the third floor classrooms. Different theories were reported with the main concern being return-air restrictions and stratified heat in the Atrium creating excessive heat load at the top level directly affecting the third floor classrooms. We noted that six air-handling units contributed to the air-conditioning of the Atrium area through 14 VAV terminal boxes returning to a common ceiling plenum through 177 return-air grilles with volume dampers specified to be set at 565 cfm each. None of the volume boxes serving the Atrium area share with other areas except for the air-handling units feeding the boxes. However, the locations of VAV-terminal thermostats in the Atrium area were such that they were being influenced by direct air-flow from the supply-air grilles. Also, the classroom thermostats were specified and placed near doorways instead of near return-air grilles or areas of the classrooms that would provide a sampling of the room condition. Typically, the room thermostats were in direct line with the supply-air discharge from nearby supply-air grilles. Further study is recommended to assess the existing conditions with the goal of determining alternate thermostat locations to better control the Atrium and classroom environments.

Also, today’s standards (ASHRAE 62.1-2004, Ventilation for Acceptable Indoor Air Quality) require a range of about .06 to .18 cfm/sq.ft. of occupied space in a typical educational facility; or approximately 7½ to 10 cfm of outside air per person. The building receives outside air ventilation through the central station air-handling units, and packaged rooftop heating and ventilation units. Therefore, the ASHRAE requirement of outside air for the occupied areas of the building is approximately 44,618 cfm based on the maximum recommended .18 cfm/sq.ft. which is somewhat less than the 93,515 cfm outside-air provided by the specified and/or presumed settings of the equipment outside air dampers. We believe that under current utilization, based on a reported student population of 1,394 the fresh air introduced into the building by the HVAC systems is more than sufficient.

We recommend cleaning and refinishing the cooling tower catwalk supporting steel to help prevent further rust corrosion. We also recommend routing the cooling tower drain and overflow though pipe to exit at a roof drain rather than discharge onto the roof membrane. Replace seven small heating water pumps in 2008.

The 20-year study period from 2008 to 2027 will require replacement of some HVAC equipment with the possible exception of the cast-iron boilers that have an expected useful life of about 45 years or more, the cooling tower installed in 2007, the chillers, and air-handling units that have an expected useful life of about 25 to 35 years. The equipment is

Pneumatic ATC and Johnson Metasys BAS systems are presumed replaced with a current technology building automation system (BAS) and integrated into local packaged control systems.

13.4.7 Electrical Systems Summary

Description

A pad-mounted transformer provided 277/480-volt secondary service to the building. The 4,000-amp. 277/480-volt 3-phase, 4-wire service provided the main electrical service entrance, and was located in the main electrical room. The service was sourced through a four-section switchboard with circuit-breaker disconnects ranging in size from 100 amps. to 800 amps., and served such equipment as the HVAC equipment, main distribution panelboards (MDPs), general distribution panelboards, and lighting.

General distribution panelboards were located in corridors or electrical rooms serving such equipment as fans, lighting, and general use distribution. The general distribution circuit-breaker panelboards fed either, 277/480-volt power for equipment and lighting, or 120/208-volt power for general use. The building was provided general-use 120/208-120/208-volts, 3-phase power through approximately 16 step-down, dry-type transformers ranging in size from 9 kVA to 300 kVA. These transformers provided a total of 1,344 kVA of 120/208-volt power to general distribution panelboards located throughout those areas of the facility. Emergency power was provided by a natural-gas-fueled engine-powered 230-kW generator and emergency power was sourced through a 400-amp. automatic transfer switch and 16 general distribution panelboards.

Wiring was noted to be a combination of copper wire with thermoplastic insulation inside electrical metallic tubing (EMT), armored cable (BX), and flexible metallic tubing (Greenfield).

(29)

April, 2008

Lighting was typically fluorescent fixtures throughout with incandescent illumination in certain areas such as the auditorium and metal halide illumination in areas such as the Atrium.

Condition

The electric service equipment appeared to be in good operating condition throughout the building with no reported or observable problems.

Depending on the lamp type, fluorescent lamp life varies between 10,000 and 20,000 hours. Lamp life for incandescent lamps ranges from 750 to 2,000 hours. Intervals for re-lamping will depend on the operating times in the different areas. Re-lamping is generally addressed as a maintenance issue. The fixtures will typically last the life of the building. Architectural changes often result in fixture changes for aesthetics before the fixtures need replacement.

Ferro-magnetic fluorescent ballasts have an estimated life of 20 to 30 years. Electronic ballasts similar to those used in compact fluorescent fixtures and those used with F32T8 lamps have an estimated service of about 15 years.

No identified repair needs were determined at this time for electrical systems other than initiating a PM program.

A preventive maintenance program of checking and inspection of all switchgear, panelboards and connections, cleaning (where required) and re-torquing electrical equipment connections should be instituted and performed every three to five years by a licensed electrician. The over-current devices should be checked for smooth operation, cleaned and lubricated as required. Fusible switch units should be checked to ensure all fuses within the switch unit are from the same manufacturer and are of the same class and rating. (It is important to note that arcing failures occur where connections have loosened as a result of thermal cycling.) Our opinion of cost for preventive maintenance every five years is $19,000.

13.4.8 Plumbing Systems Summary

Description

The domestic water service entrance fed distribution through the building via copper piping believed to be type L.

Three storage-tank type gas-fired domestic water heaters, each rated at 800,000 Btu/hr. provided domestic hot water for the restrooms, janitor sinks, and showers. The main two water heaters had 400-gallons storage capacity each and the heater dedicated to showers had 600 gallons storage capacity. A ¾-hp in-line pump provided general circulation to the building, and a ½-hp in-line pump provided circulation to the showers.

(30)

April, 2008 Toilets and urinals were typically vitreous china flush-valve types. Lavatories were noted to be floor mounted and cantilevered porcelain cast-iron.

Sanitary piping and vents and storm water piping was noted to be cast-iron and a duplex 1-hp sump assisted with storm water removal.

Condition

Overall, the domestic water systems in the building appeared to be in fair to good condition. No leaks or other problems were observed or reported. The observable piping appeared to be in good condition with no evidence of leaks or reported problems except for the main circulation pump that appeared to be in poor condition with evidence of past leaks that appear to be stopped by mineral solids.

No identified repair needs were determined at this time for the plumbing systems except for the possible replacement of the domestic hot water circulation pumps.

The domestic water piping and drainage system has a life cycle of about 40 to 50 years. Future repairs should be manageable by the maintenance staff over the near term and no major expenditures beyond routine maintenance are expected except for the circulation pump.

The domestic hot water circulation pump appears to be overdue for replacement and should be scheduled for 2008. Our opinion of cost to replace the hot water circulation pump is

$1,200.

The domestic water heaters will reach the limit of their 15-year expected useful life by the year 2011 and should be scheduled for replacement. Our opinion of cost to replace the domestic hot water systems is $35,000.

13.4.9 Conveying Systems Summary

Vertical transportation was provided by two Otis oil/hydraulic elevators located at strategic areas of the facility. Each elevator was powered by an electric-motor-powered hydraulic pump system with an electronic/electrical/mechanical relay control system. The main elevator made three stops and had a rated lift capacity of 3,500 pounds. The penthouse elevator made five stops and had a rated lift capacity of 3,000 pounds.

Each elevator car had stainless-steel pocket doors with an interior stainless-steel finish and an exterior painted finish. The Penthouse elevator car had both front and rear doors. The elevator cars each had decorative laminated paneled walls with stainless-steel trim and fluorescent ceiling lights. Floor finishes were vinyl composition tile (VCT). Each car was equipped with multi-beam, infrared proximity detectors, a passenger telephone, illuminated

(31)

April, 2008

push-button control panels with Braille labeling, in-car direction lanterns and visual and audible car position indicators.

The elevator lobby call stations were the illuminated push-button types. No issues were reported with the proper operation of the elevators.

Condition

The elevators were original to the building construction and appeared to be in good overall condition. The elevator machine rooms appeared to be well maintained and all equipment appeared to be in good condition. The elevators are reportedly under a full maintenance contract with Schindler Elevator. According to data in the machine rooms, the elevators were last inspected by Schindler Elevator on July 10, 2007.

No identified repair needs were determined at this time for conveying systems.

The drive machinery and controls have an expected useful life of about 20 years, and the hydraulic piston and leveling equipment has an expected useful life of about 25 years. We expect that the elevators will require complete renovation within the study period including replacement of major components. The work would include replacement of the hydraulic cylinders, re-drilling the well holes, replacement of the pumping and control systems, replacement of the door operators, locks, hangers, closers and tracks. Our opinion of cost to renovate both elevators in 2021 is $200,000.

13.4.10 Fire & Life Safety Issues

The applicable building code referenced in this evaluation is the Maryland State Fire Prevention Code, 2007 Edition, which incorporates by reference NFPA 1 Uniform Fire Code (2006 Edition), NFPA 101 Life Safety Code (2006 Edition) and certain requirements of the International Building Code (IBC). Additionally, the 2006 Howard County Amendments to the Maryland Building Performance Standards (MBPS), as prescribed in COMAR .05.02.07.01 thru .09, include the 2006 International Building Code, again with state amendments.

In general, existing conditions are grandfathered pending any new rulings by the Authority Having Jurisdiction (AHJ), usually the Fire Marshall. A change could be directed if a degree of hazard develops that would make it prudent to upgrade or extend an existing system. Any future additions would normally not trigger a requirement to upgrade fire protection systems in existing spaces if firewalls were installed or already in place between the existing spaces and the new addition.

A detailed list of observed Fire/Life Safety topic deficiencies and locations has been provided to HCPSS School Facilities under separate cover.

(32)

April, 2008 Description

The school building is for the most part protected throughout with a wet pipe automatic sprinkler system. There are a few small areas within the building however that lack code compliant sprinkler coverage.

Observations

As stated above, the automatic sprinkler system is for the most part installed throughout the entire building. There are numerous areas that have been identified as lacking code-compliant sprinkler coverage and a detailed list was provided under separate cover. A number of sprinklers were identified as being excessively dirty to the point that the

glass bulb actuating element may be delayed in its operation in the event of a fire. Other sprinklers were observed as having debris hanging from them. Still others had tape on them from painting work in the immediate vicinity. Lastly, other sprinklers simply had their escutcheons either missing or partially off. These sprinklers should be cleared of the debris, the dirt removed (carefully), and/or the escutcheon reinstalled appropriately. A detailed list of locations of dirty sprinklers was provided under separate cover.

A number of sprinklers were observed with paint on either the deflector, the glass bulb actuating element, or on the soldered link & lever fusible link. These sprinklers must be replaced with new. These sprinkler locations were provided under separate cover.

There were auxiliary drains for low point drainage of the system that were found but were not properly labeled as such.

First floor, across from elevator #1 (nearest auditorium); glass in door of fire extinguisher cabinet is broken.

Auditorium sound booth/room; fire extinguisher not properly mounted on wall or inside listed fire extinguisher cabinet.

Fire Protection: Standpipes

With the exception of the stage area within the auditorium which contains a modified standpipe/hose connection system of two outlets, a standpipe system is not present in the building.

Fire Protection: Alarms Description

The building is provided with an addressable fire alarm detection and signaling system. For the most part, the system appears to be functional and code compliant with the following exceptions:

Observations

The existing addressable building-wide fire alarm system is currently performing satisfactorily and is in good working condition with no trouble signals present.

Fire Protection: Structural Description

The building is considered to be a Mixed Use Group Occupancy with Educational Use Group (E) being the primary occupancy with Assembly Use Group (A) being secondary. The building construction type appeared to be of Type IA construction, which was characterized

(33)

April, 2008

by protected steel and concrete construction. As such, the building height and area limitations were based on the more restrictive of Use Groups E with Type 1A construction. Based on the applicable codes the building is considered code compliant for height and area. Observations

In general, the structural components of the building appeared to meet fire protection code requirements for a building of its height and use. There were no major issues identified with regard to the building’s existing structural fire protection features. Minor issues have been identified and are included below in this section.

Penthouse, south side, center (above pumps); spray-applied structural fireproofing damaged and/or missing.

2nd floor, stair #3 (northwest corner); spray-applied fireproofing on structural steel members in stairwell appears to be damaged and in the process of being worn off by building occupants over time.

Room C-173 (near auditorium); significant amounts of spray-applied structural fireproofing damaged and/or missing.

Elevator #2 machine room, basement floor; significant amount of spray-applied structural fireproofing damaged and/or missing.

Fire Protection: Means of Egress Description

The building’s overall means of egress implementation is considered code compliant. There were a few items worthy of noting which in and of themselves are not considered major, but within the entire building egress design they are critical. These items included the following: Observations

There were no major issues identified with regard to the building’s existing means of egress arrangement. Other issues besides those below have been identified and provided under separate cover.

On roof, south of penthouse; ladder from upper to lower roof greater than 20-ft without a cage to enclose ladder.

Carpentry area/prop construction (across from mini-theatre), west and south wall; accessible area used for storage not properly safeguarded with railings and/or a ladder. Inside the mini-theatre on the north wall, an accessible area up off of the floor used for

storage is not properly safeguarded with railings and/or a ladder. Exit sign is not working in/near the stairwell closest to the mini-theatre.

On the 2nd_{floor immediately outside the auditorium on the east side (the south door)}

there should be an exit sign directing occupants toward the stair to the south of that point. Fire Protection: Smoke Control

A smoke control system by definition is not present in the building. However, there exists a rather unique method of smoke exhaust from the atrium. Fans in the penthouse mechanical room dedicated solely to exhaust operate upon beam and/or spot-type smoke detector actuation in any area contiguous to the atrium. Makeup air is achieved via automatic opening of the main doors to the building. The main air handling units are

(34)

April, 2008 equipped with duct smoke detectors in either or both the supply and return ducts which activate to initiate fan shutdown.

The general storage in the penthouse must be removed and/or relocated to an appropriate location so as to ensure unimpeded exit access for occupants in the space. (NFPA 101, Chapter 7) Approximate cost is $1,000 which includes related moving expenses.

Add automatic sprinkler coverage inside the media office on the 2nd floor above the window facing the open atrium area to sheet the window with water in the event of a fire. This will help to maintain the required separation of the atrium from adjoining spaces. (IBC 705) Approximate cost to add one sprinkler over the window is $1,500. Replace painted sprinklers with new. All sprinklers should be in proper working

order. Paint on the fusible element of a sprinkler will prevent the sprinkler from operating as it was designed. All sprinklers identified as being painted should be replaced. (NFPA 13, Chapter 8). Approximate cost to replace all identified painted sprinklers is $4,000.

Install new and repair and relocate existing exit signs as described above. (NFPA 101; 7.10.1.2) Approximate cost is $1,200.

Replace fusible link on roll-up fire door. The roll-up fire rated door should be restored to proper working order. This will result in the replacement of the currently painted fusible link on the stage side of this door (above the door opening). The door should be able to close automatically in the event of a fire and provide the code required separation of the auditorium from the adjacent school areas. (IBC Chapter 7). Approximate cost is $500.00.

Repair spray-applied structural fireproofing. To ensure the building remains classified as Type IB, non-combustible, protected, fully sprinklered, all areas identified in this survey with missing, damaged or incomplete fire proofing should be repaired. (IBC Section 714 and Table 601) Approximate cost is $5,000.

Repair, replace and provide new handrails and ladders. (NFPA 101; 7.2.2.4.1) Approximate cost is $4,500.

Clean and replace as necessary all other sprinkler system related items identified above. This includes all dirty sprinklers, sprinklers with debris and/or tape on them, etc. The automatic sprinkler system shall be maintained in proper working order. (NFPA 13, Chapter 8) Approximate cost is $7,500.

Remount/hang fire extinguisher in the auditorium sound room and repair the fire extinguisher cabinet identified. (NFPA 10, Chapter 7) Approximate cost is $100. Ensure adequate emergency lighting levels along the corridor to the rear of the

auditorium stage area. Currently the blue colored paper filters the lights that are on the emergency circuits. (NFPA 101; 7.9) Approximate cost: $0. Simply remove the blue paper.

13.4.11 Interior Finishes Summary

Floor coverings: The interior consisted mainly of vinyl floor tile in hallways and classrooms, and carpeting in classrooms and offices. Floor conditions were generally good. Vinyl floor tile is in good condition, carpet is in fair to good condition. Restrooms floors were almost exclusively ceramic tile.

Wall coverings: Interior walls were painted CMU block and painted drywall. Restroom walls had combinations of CMU block and ceramic tile. Paint conditions were good and the atrium was being repainted during this assessment.

Ceiling systems: The majority of interior ceiling systems are suspended grids with either 2 x 2 or 2x 4 foot drop in tiles. Some drywall ceilings exist in restrooms and locker rooms. Music rooms and the auditorium have acoustical features and tiles. Ceiling tiles were generally in fair to good condition with some areas of stained tiles. Interior lighting: Interior lighting is almost exclusively fluorescent lighting fixtures of

either 2 x4 or 1 x4 sizes.

Interior doors: Interior doors were in fair to good condition.

No immediate major repairs are required at this time to interiors.

Repaint Interior. Repaint interior wall surfaces throughout school in 2008 (scheduled HCPSS effort).

Replace carpets. Replace carpets in phases beginning in 2008 (34,000 SF per cycle)

Replace Floor Tile. Replace partial floor tile in 2013 (20,000 SF). Refinish gym floor. Refinish gym floor in 2010 and then every 7 years.

Replace ceiling tile. Replace partial ceiling tiles in phases every five years beginning in 2015 (20,000 SF per cycle).

13.4.12 Accessibility Issues

Only a cursory review of ADA issues was included in this effort. Any significant ADA items noted during assessments were included in their specific system sections. ADA signage was one wide-spread issue that could be improved at most schools. This would require a subsequent review and signage upgrade. Another issue is a limited number of accessible restrooms in older schools. Attempts have been made to provide ADA restroom accommodations in select locations at all schools, but the original construction of some schools has imposed physical limitations on the ability to install large enough restroom stalls to be fully-compliant. Newer schools buildings and additions with restrooms are being provided with accessible facilities.
