2.2 CIVIL

2.2.1 Site Grading and Storm Drainage

7 | P a g e

Current parking area in its existing condition does not contain adequate slopes for storm water to sheet off for drainage. Slope remediation required for the removal of water pooling areas and erosion from foundation.

- Perform a topographic survey to verify the condition of existing grade elevation and ground level then adding in a 2% slope of grading leading from buildings foundation outward to perimeter fence into sewer lines.

- Storm gutters on roof need to be extended to prevent excess water build-up on roof and proper drainage from roof to lower level away from the building.

- Foundation slope needs to also be added around outdoor electrical transformer foundation to prevent erosion to transformers foundation.

Verify all previous construction is matching previous construction plans from last contractor before improvements begin. Manholes for water and sewer lines need to be inspected and cleaned. Some have been left open and consist of debris and some have been closed shut since last contractor attended site causing difficulty when opening. All openings to the environment should be covered to prevent any further debris and/or animal entry until proper

8 | P a g e windows and/or louvers can be installed.

2.3 STRUCTURAL

2.3.1 Exterior Recommendations

Multiple areas around the exterior, load-bearing walls have clear indications of water ponding that are likely compromising the foundation. The original site development and preparation are unknown, however, the ponding areas observed align with interior masonry cracks which are indicative of differential settlement and foundation rotation. There are also cracks on the roof along the plant room wall on the perimeter of the structure. Some cracks are badly damaged and show a clear break through the entire structure depth. Other cracks aligned parallel to the base of the plant room along the structural perimeter wall. Slab seems to be floating and foundational footers are unknown.

Required Actions

Filling of erosion areas with the proper foundation repair such as soil fill or polyurethane foam to close openings. Excavate ponded areas to foundation and backfill in compacted lifts. If any areas under the foundation is found to be scoured or cracked, additional investigation should be performed to determine if underpinning is needed for strengthening the foundation to prevent further settlement. In addition, it is the perimeter of the facility be scarified and backfilled with additional fill to provide a compacted, 2% slope away from the facility to prevent any additional/future water intrusion. Roof cracks need to be filled in with proper cement and bonding agents to prevent spreading of cracks.

Testing done for the bearing capacity of the soil for the spread footers shall be in in accordance with ASTM D1194 and provided to the COR prior and post remediation

2.3.2 Interior Recommendations

Multiple interior cracks are displayed throughout the interior of the building within the hallways, kitchen, bathrooms and office areas. Major interior cracks align with outside ponding areas which shows evidence of foundation settlement. Vertical and horizontal cracks should be exposed back to the masonry infill to determine if they are cosmetic (stucco/plaster) or structural.

Concrete blocks (CMU) are not braced to concrete moment frame above and need proper bracing attachments.

Slab is in unknown condition and cracks as well as sinkage indicate major structural failure of the slab.

Entrance doors do not close properly and lack weatherstrip and is allowing water to drain into facility.

Required Actions

After foundation repairs are complete, all finishes that are cracked need to be removed and epoxy injections are recommended to prevent further issues. Cracks should be cut out to determine the severity of the crack, after foundation investigation and repair is complete to determine scale of damage. Stucco/plaster are to be reapplied and repaired to all internal walls at a depth specified in IBC code requirements.

Review design criteria for seismic calculations to determine which CMU walls are participating elements and braced accordingly. Cover all openings to the facility that allow environmental elements and animals to enter.

CMU wall at the end of the firing range on the west side of the building needs to be brought up to the ceiling and properly tied in with sound proofing and ballistic resistance in accordance with (Unified Facility Criteria) UFC 4-179-02. Sound proofing shall also be installed in the weapons cleaning room.

10 | P a g e

Test, install and remediate issues with the targeting system to ensure it operates correctly and in accordance with UFC 04-179-02. The system must be controlled from the main control station, with all side panels functioning. Remediate any issues found during testing.

2.8 ENVIRONMENTAL

2.8.1 Vegetation

Remove all weeds, vegetation, and leftover debris from previous construction. Ensure the site is cleared before the final project turnover.

2.9 FIRE SURPRESSION

2.9.1 Fire Alarm Replacement

Fire alarm systems have been installed, few are misplaced on the exterior of building and need to be removed and reinstalled on interior. Exit signs need to be replaced or confirmed that the currently installed signs are functional. Water system for fire protection needs to inspect and tested for pressure and functionality.

- Installation of Fire alarm systems must be in compliance with the NFPA 72 and in the locations required in the drawings.

- A material submittal and fire alarm plan must be submitted to COR prior to the start of work.

2.9.2 Fire Suppression System Installation

Fire Suppression system is not installed in the building. A fire suppression sprinkler system will need to be installed in the building that covers all rooms. This includes a fire pump, risers, and a water study to ensure adequate water pressure. A detailed plan for the water

18 | P a g e suppression system needs to be created and approved by COR prior to installation.

- Detailed engineered plan that adheres to National Fire Protection Association (NFPA) 13 and other applicable NFPA standards, will be needed to be submitted and approved by the COR prior to work on this section commencing.

- System must be tested and meet the standards of the NFPA 13 and NFPA 4.

Testing includes flow tests, and functions testing.

- Additional water calculations need to be done for a fire sprinkler system and adequate water pressure on site must be achieved.
