Room requirements include a general storage area consisting of 3 cage storage areas with storage racks, overhead door access, and work benches (by others), and toilet room.

Civil scope

DESIGN CRITERIA

The following criteria references shall be used in the design of this project where they apply to the required scope of work:

1. Project RFP

2. UFC 3-201-01 - Civil Engineering

3. AASHTO Assoc. of State Highway & Transportation Officials

4. NCDOT North Carolina Department of Transportation

5. NCDEQ Sedimentation and Erosion Control Manual

Existing Site Conditions

The project site is located north of Anchor Road between Rifle Range Rd on the west and Globe Rd on the east. The site fronts on an existing large, paved parking and access area with existing catch basins. The MRSG building is located directly south of three existing warehouse buildings of similar size and is situated inside of a fenced compound. The site is grassed and the surrounding area to the east is mostly open with grass and tree cover, and several storm ponds.

Demolition will include clearing and grubbing the turfed area, and chain-link fence removal and relocation around the MRSG building to include it within the fenced compound.

Proposed Site and Utility Features

A heavy-duty concrete apron will be provided for vehicular access from the existing paved parking and access area to the building. The concrete apron will consist of a rigid pavement section of 6” of

650 psi flexural concrete with WWF mesh and 6” NCDOT aggregate base course over an approved subgrade. Pavement and sidewalk patches will match existing sections and be performed in a neat manner.

To assist drainage at the impervious areas, a trench drain will be provided along the full width of the loading apron, daylighting to graded swale south of the new building. The building site will be graded to fall towards the naturally sloping undeveloped areas east of the building.

Protective bollards will be utilized at building service doors where vehicular damage could occur.

An existing water distribution line runs in the east-west direction to the south of the site and a new water service and fire service line will be installed to serve the new building. An existing sanitary sewer collection line runs to the north of the building site in the east-west direction and a new sanitary sewer service line will connect to this main and terminate with a clean-out approximately

5-feet outside the building. These service lines are tapping existing utility mains and NCDEQ water and sanitary sewer permits are not required.

An existing overhead electric line passing over the building site will be relocated by providing a new power pole southeast of the building site. A pad mounted transformer will be provided on site with underground primary provided from the overhead service at the relocated power pole, with underground secondary from the transformer to the building. An existing communication manhole located south of the site will provide communication lines extended to an existing comm handhole near the northeast corner of the building.

All disturbed areas will be sodded.

Stormwater and Erosion Control

The existing drainage patterns on site will be maintained to the maximum extent possible with building downspouts discharging via concrete splash blocks to grade and sheet flowing across the site.

Erosion and sedimentation control measures will be utilized during construction to prevent sediment from leaving the site.

Disturbance on site is limited to less than the required threshold, therefore no environmental permits are expected to be required for this project.

Plumbing scope

DESIGN CRITERIA

UFC 3-420-01 Plumbing Systems (UFC)

PLUMBING SYSTEMS

The plumbing systems within the facilities will consist of the following plumbing fixtures:

• Water Closet

• Lavatory

• Service Sink

• Bi-level Water Cooler

• Wall Hydrant

DOMESTIC WATER CALCULATIONS

14 Water Supply Fixture Units (WSFU)

30 GPM, 1-1/4” Dia. Main

SANITARY SEWER CALCULATIONS

11 Drainage Fixture Units (DFSU)

This equates to a 4” sanitary sewer main @ 1/8” per foot slope

HOT WATER CALCULATIONS

Mixed Water Temperature Equation: P = (Tm – Tc) / (Th-Tc)

Th = Supply hot water temperature

Tc = Inlet cold water temperature

Tm = Desired mixed water temperature

P is the hot water multiplier, which is expressed as a percentage.

P = (122 – 60) / (140 – 60)

P = 62 / 80 = .78

1.75 GPM (shower demand per head) x .78 = 1.37 GPM

1 shower x 1.37 x 60 minutes = 82.2 GPH

Additional fixtures:

(1) Lavatory x 6 GPH = 6 GPH

Subtotal – 6 GPH x .3 (Demand Factor) = 1.8 GPH

Total – 82.2 + 1.8 = 84 GPH Peak Demand (1 hour)

The water heater specified is 80 gallon (64 gallons available total) with 4.5 kW input and recover a total of 21 GPH at 90-degree rise. Therefore, 85 gallons is available to meet the one-hour peak demand.

FIXTURES AND EQUIPMENT

Water closet will be floor mounted, bottom outlet, dual flush valve, elongated bowl with open front seat less cover. Water usage will be 1.6 / 1.1 gallons per flush.

DESIGN ANALYSIS

Building Description

The MRSG DST Storage Facility consists of a 6,000-sf one-story building. The primary use of the facility includes storage and support spaces (e.g., toilets). The building will be a pre-engineered metal building. The facility will be equipped with automatic sprinkler protection throughout the building. Code allowances for fully-sprinklered buildings will be applied.

Occupancy

1. The primary use of the building will be for storage.

2. For IBC compliance the facility will be classified as a Group S-1, Moderate Hazard Storage [IBC

§311.2] occupancy.

3. For LSC compliance, the facility will be classified as a storage [LSC Chapter 42] occupancy [LSC

§6.1.13.1 & LSC §42.1.5].

4. Special hazard areas including any mechanical, utility, and electrical areas are considered incidental to the main occupancy. These areas are required to be protected in accordance with

LSC Section 8.7.1.

Construction Requirements

1. The minimum construction type of a structure is required to comply with the fire resistance requirements and fire area limitations in UFC 3-600-01 and the IBC. The minimum construction type of a building is typically based on the height, area, occupancy, open street frontage, and automatic sprinkler protection provided in the building.

2. In accordance with IBC Chapter 5, the building will be constructed to be Type IIB construction.

The height and area limitations in Table 3.1 apply to the building for confirming the minimum required construction type.

c Not less than the fire resistance required by other section of the code.

5. The roof coverings and roof deck assemblies must be in accordance with UFC 3-600-01 Sections

15-1 and 15-2.

Exterior Fire Exposure

1. The requirements for providing fire resistance-rated exterior walls and openings are based on the fire separation distances (FSD) between buildings and the occupancy groups within the buildings.

2. The fire separation distance is defined as the distance measured from the building face to the closest interior lot line, to the centerline of a street or public way, or to an imaginary line between two buildings on the same lot [IBC §602].

3. The fire separation distance is a measure of the separation to a point along a line between buildings, not the actual distance between buildings. The fire separation distance is measured at right angles from the face of the wall.

4. Once the location of the lot line is established, all future provisions must be based on this lot line and applied to both buildings. Where the lot line is not parallel to the exterior wall of a building, the required fire resistance rating may vary along the building side.

5. For building sides not fronted by a street, the fire separation distance is measured to an imaginary line between the buildings assuming the buildings are located on the same property

(i.e., an interior lot line).

6. Where a new building is erected on the same lot as an existing building, the code requires the assumed property line to be located such that the existing building complies with exterior wall and opening protection criteria [IBC §605.3].

7. The fire-resistance rating of exterior walls with a fire separation distance of 10-ft or less shall be rated for exposure to fire from both sides [IBC §705.5].

8. The exterior walls are required to extend the full height of the building and be constructed to remain in place for the duration of time indicated by the required fire-resistance rating

[IBC §705.6].

9. The code requirements for the fire-resistance rating and exterior wall openings are provided in

Table 3.3.

10. The Storage Facility is at least 40-ft from the adjacent buildings and any other structure on all sides. This provides a FSD of at least 30-ft from the adjacent buildings to an imaginary lot line and at least 10-ft from the imaginary lot line to the Storage Facility. The exterior wall of the building is not required to have a fire-resistance rating and there is no limit on the area of openings [IBC §705.8.1 Exception 2].

11. Openings in the exterior wall are required to be in accordance with IBC Section 705.8.3.

HVAC Systems

1. Air handling, HVAC, and exhaust systems, including fire/smoke dampers, are required to comply with NFPA 90A except as modified by UFC [UFC 3-600-01 §28-1].

2. Fire dampers are required in ductwork or air transfer openings that penetrate fire resistance rated assemblies. NFPA 90A permits the deletion of fire dampers in fully ducted penetrations of

1-hour fire resistance-rated partitions.

3. The installation of duct detectors is required to comply with NFPA 90A. Smoke detectors listed for use in air distribution systems shall be located downstream of the air filters and ahead of any branch connections in air supply systems having a capacity greater than 2,000-cfm [NFPA 90A

§11.4.2.1 (1)].

4. Plenum spaces may be used as part of an air handling system where the plenums comply with

NFPA 90A [UFC 3-600-01 §28-1.2]. Rooms or areas that form a plenum space or that are used as a plenum must not be occupied for any purpose except during repairs and maintenance operations to the air-handling equipment [UFC 3-600-01 §28-1.2].

Interior Finish Materials

1. Interior walls and ceiling finishes are required to comply with UFC 3-600-01 Section 8-1 which requires wall and ceiling finishes, and movable partitions to conform to the requirements of the

LSC. The LSC restricts the use of certain materials as interior finishes on walls and ceilings based on the flame spread rating and smoke development rating of the material. Interior wall and ceiling finishes shall be classified in accordance with ASTM E-84.

2. The interior finish materials shall be grouped in the following classes, based on their flame spread rating and smoke developed rating [LSC §10.2.3.4]:

Class A – Flame spread 0-25, smoke developed 0-450

Class B – Flame spread 26-75, smoke developed 0-450

Class C – Flame spread 76-200, smoke developed 0-450

3. Table 3.5 summarizes the interior finish requirements for the Storage Facility [LSC Table A.10.2.2 note (6)].

Table 3.5: Minimum Interior Finish Requirements

Note: Automatic sprinkler protection allowances have been applied.

4. The codes also specify requirements for interior floor finish and floor covering materials. Floor coverings other than carpet shall have a minimum critical radiant flux of 0.1 W/cm2 [LSC

§10.2.7.2]. Interior floor finish materials shall be classified in accordance with NFPA 253, Standard Method of Test for Critical Radiant Flux for Floor Covering Systems Using a Radiant

Heat Energy Source as follows [LSC §10.2.7.4]:

Class I – Critical radiant heat flux ≥ 0.45 W/cm2

Class II – Critical radiant heat flux ≥ 0.22 W/cm2

5. There are no additional requirements for floor finish in all areas for storage occupancies [LSC

Table A-10.2.2, Note 6].

Means of Egress

Means of egress are required to comply with the LSC except as modified by the UFC [UFC 3-600-01

§10-

1.1]. Where egress elements serve multiple occupancies, the most restrictive requirements apply.

Occupant Load
