DIVISION 2 –

Earthwork See File 7-ConstructionMinMtsReqTestFreq Construction Minimum Materials Requirements and Testing Frequencies

Excavation and Fill

1. All borrow or spoil operations shall be off Government controlled property at the responsibility and expense of the Contractor. Fill will be placed in (1) one foot lifts and compacted with a minimum of two passes of a soil compactor to achieve a minimum of 85% compaction. The Contractor shall test for compaction as directed by the Contracting Officer’s Representative. Minimum testing is anticipated pending satisfactory performance. Clean fill is any material classified as a satisfactory material but cannot contain roots and other organic matter. Concrete and asphalt rubble void of reinforcing steel, and rocks and stones no larger than (4) four inches in diameter. Clean fill shall not contain more than 100 parts per million (PPM) of total petroleum hydrocarbons (TPH) and not more than 10 PPM of the sum of benzene, toluene, ethyl benzene, and xylene (BTEX).

Section 02050 Demolition - Any hand receipted items shall always be salvaged and turned over to the Defense Reutilization and Marketing Office (DRMO), located in Building 4195.

Sections 02051, 02080, 02091- General Hazardous Material Disposal procedures:

Standard procedures are as follows: Environmental Office will sign manifests for all material disposed off post. Materials of different types cannot be mixed in the same container. While in use for collection at demo sites, waste containers must be properly marked, and closed and secured at all times when sites are not manned. It is suggested that no storage for over a week be allowed. The Contractor shall pay all landfill and disposal fees. The Contractor will pay asbestos removal charges to state. A survey will always be required for rehab or any projects involving building demo. Usually a building survey is done (upon start of a project) by the Fort Worth District team, 502ND CES in-house forces, or an AE team. The survey and its results should be discussed with Environmental Management Office project manager during the concept design conference and all succeeding conferences, to ensure a clear scope of work and a clear understanding as to how all wastes are removed and disposed of. Disposal sites for clean debris (including uncontaminated concrete, soil, masonry and rubble) may be designated by 502nd CES on large projects such as barracks rebuild. On any project with large amounts of waste soil, contact 502nd CES for a disposal site. Building alteration specs and especially Division 2 specs such as Section 02051 should be carefully edited.

The following specific items are addressed:

1. Asbestos Containing Material (ACM)

a. All ACM waste being disposed of will be the Contractor’s responsibility, 502nd CES Environmental will sign manifests as has been standard procedure. In total demolition of buildings, mastic and floor tile (non-friable) must be disposed of properly by the Contractor.

b. All notifications of asbestos removal to the state shall be signed by Chief, 502nd CES Environmental Compliance Office.

2. All lead-based paint waste being disposed off post is the Contractor’s responsibility.

3. CPS Energy will check electrical equipment for polychlorinated biphenyls (PCB’s) on an as needed basis. Any equipment, including light ballasts, found to contain PCB’s will be disposed of by the 502nd CES Environmental Office, Bldg. 4196. If ballasts are unmarked, they will have to be considered PCB contaminated and also turned over to the 502nd CES Environmental Office.

4. Light bulbs containing mercury (including most fluorescent) will be disposed of by the Contractor. Every effort must be made to keep from breaking - packing boxes are available which will help. The same will apply to thermostats containing mercury.

5. Regulated refrigerants in old refrigerators, compressors, etc. will be purged in accordance with state regulations and the refrigerant turned in to 502nd CES Supply. Pre-arrangement for delivery of the refrigerant is required. Contact 502nd CES Environmental Compliance Office for instructions.

6. If the presence of any unusual items such as tritium powered exit lights, cesium element smoke detectors, etc. is confirmed, contact 502nd CES Environmental Compliance Office for instructions.

502nd CES Environmental Compliance Office POC – Chief David Walker, phone (210) 221- 4967.

Section 02222 Excavation, Trenching, and Backfilling for Utilities Systems

1. A tracer wire and warning marking tape shall be installed with all water, force main, and gas utilities service and distribution lines. Tracer wire shall be #10 direct burial solid copper. Tracer wires shall be installed below pipe and bedding, so wire is not disturbed during repairs. The tracer wire shall be continuous between valves, handholds, and manholes. The tracer wire shall surface at each manhole, handhold, and valve box. A coil of at least one foot of wire shall be left in each manhole, and valve box. The tracer wire shall be tested and proved continuous prior to final inspection with 502nd CES. Warning marking tape shall be color coded, installed 12" below grade, no foil or conductive backing. Comply with Encl. 4 for typical detail.

2. Grade 5 and Grade 6 crushed rock backfill may be used for backfill provided this material is installed in no more than 1 foot lifts and compacted with a vibrating plate. All backfill around manholes and valves shall be cohesive type. The cohesive material will allow any leakage of defective valves or joints to surface so they can be identified for repair.

Section 02225 Earthwork

1. Do not allow stockpiling of any material or parking vehicles or equipment within tree drip lines. Provide for temporary fencing along outside perimeter of drip line, not 5’-0" from trunk.

Section 02660 Water Lines Water Meter Installation Requirements

A water meter will be required at each building or facility. Water meters will be equipped with electronic or radio frequency (RF) transmitters for remote monitoring. The method of remote monitoring via RF transmitters must be coordinated with the installation UMCS/EMCS system. Remote monitoring will be coordinated with the individual installation. To have all water meters reading back to a central location would be expensive and is not justified. The designer will consider the placing of selected or zoned water meters in the UMCS/EMCS system. The above guidance will be interpreted as meaning remote reading to a nearby location as in the case of water meters located within buildings, basements, or generally inaccessible areas. Such installations will provide remote reading capabilities to a convenient location outside the building or structure to simplify the reading of the meter.

Also see Specification 01 35 13 – SPECIAL PROJECT PROCEDURES FOR FORT SAM HOUSTON. Include FSH water metering instructions for the contractor.

Use of Reclaimed/Recycled Water

Water Purveyor: San Antonio Water Systems (SAWS) is the regulatory body governing the use of Reclaimed/Recycled Water. The recycled water definition applies to reclaimed, reuse, and non-potable water.

http://www.saws.org/Our Water/recycling/handbook/index.shtml

All facilities designed for the use of Reclaimed/Recycled Water System shall follow Texas Commission of Environmental Quality (TCEQ) rules and regulations, Chapter 210 for the Use of Reclaimed Water, and Chapter 290 Rules and Regulations for Public Water Systems.

Additionally all facilities requiring the user of Reclaimed/Recycled Water will follow all rules and regulations set forth by the Water Purveyor (SAWS) as described in the San Antonio Water Systems Recycled Water User Handbook, and San Antonio Water Systems Cross Connection Control and Backflow Protection Program. To obtain current SAWS Backflow documents go to http://www.saws.org/business center/specs/

SAWS Reclaimed Water POC: Pablo Martinez 233-3673.

Section 02685 Gas Distribution System

1. Provide a gas pressure regulator and meter detail. All buildings served, except family housing units, shall be metered. The meter shall have a valved bypass so if the meter is removed for servicing, the building can still be supplied with gas. Provide three quarter inch plugged taps on each side of the pressure regulator so the pressure regulator can be checked for proper operation.

2. Provide Poly valves in lieu of metal for underground gas valves.

3. CPS Energy will make the determination whether or not the distribution pressure gas service is sufficient to serve the proposed project. CPS Energy will indicate the location where the distribution pressure gas will be tapped.

4. A tracer wire and marking tape shall be installed with all gas service and distribution lines. Tracer wire shall be #10 insulated solid copper. Tracer wires shall be installed below pipe and bedding, so wire is not disturbed furring repairs. The tracer wire shall be continuous between valves, handholds and manholes. The tracer wire shall surface at each manhole, handhold, and valve box. A coil of at least one foot of wire shall be left in each handhold and valve box. Tracer wire shall come up at regulator 18 inches and wrap around riser for access. The tracer wire shall be tested and proved continuous prior to final inspection with CPS Energy. Warning marking tape shall be color coded, installed 12" below grade, foil backing is not necessary.

5. Provide anodeless riser to regulator.

6. Lines to regulators shall be not less than one inch.

7. Use PE rather than ferrous metal underground when feasible, to avoid requirement for cathodic protection. PE valves are available up to 8 inches – try to limit gas valves to 8 inch. Ensure valve boxes are at least 6 inches or larger to provide access for wrench.

8. Comply with Specification 01 35 13 – SPECIAL PROJECT PROCEDURES FOR FORT SAM HOUSTON. Include permanent site natural gas and CPS Energy requirements.

CPS Energy Gas POC: Mr. Daniel Davila (210)353-5845 drdavila@cpsenergy.com.

Section 02720 Storm Drainage System

The minimum size culvert pipe under roads and entrances shall be 24 inches in diameter. 502nd CES has determined that the smaller diameters are too difficult to clean when silted up.

Section 02730 Sanitary Sewers

1. Minimize the use of sewer lift stations. If lift stations are required, provide a packaged unit assembled of coated metals that do not easily corrode. Provide an audible and visible alarm in case of a malfunction. In remote areas an FM signal shall be sent to 502nd CES - coordinate with existing electronic systems. Make sure that the location of the lift station is accessible for 502nd CES service trucks. If the location is remote and away from the main roads, provide a gravel surfaced road to the lift station.

2. If a drop manhole is needed, detail same on the bid documents. Use a drop manhole if the elevation change is more than 18 inches (per standard criteria).

3. Provide exact coordinates to an accuracy of six inches and invert elevation to an accuracy of one tenth foot for the sewer connection to the building. Provide this information on both the plumbing and civil drawings so the plumber and utility contractors are forced to talk to each other.

4. Use SDR-26 PVC pipe for sewer piping. Use PVC rather than ferrous metal underground, to avoid requirement for cathodic protection. Waiver required

5. Minimum size sewer main is 8 inches. Variance of 6” sewer will be allowed if existing sewer pipe tie-in line is 6”.

6. Minimum 6 inch sewer connection to buildings so the maintenance personnel can jet rather than rod a plugged sewer line.

7. Provide two way cleanouts every 150 feet along a sewer branch connection from a building.

8. Provide two way cleanouts at the sewer building connection.

9. Provide a manhole at every change of direction of the sewer line and every 400 feet.

10. A tracer wire is not required with a sewer pipe system.

11. All sewer lines under buildings shall be PVC, SDR-26 in lieu of cast iron.

12. Master Planner Sanitary Sewer POC: Mr. Robert “Bobby” Mengden (210) 233-3679 rmengden@saws.org.

Final stabilization is established at the disturbed site when all soil disturbing activities at the site have been completed and a uniform perennial vegetative cover with a density of 70% of the native background vegetative cover for the area has been established on all unpaved areas and areas not covered by permanent structures, or other stabilization measures (such as riprap, gabions, or geotextile)

4. The turfing work shall be accomplished only when satisfactory results can be expected during PLANTING SEASON periods indicated. When conditions such as drought, excessive moisture, high winds, or other factors prevail to such an extent that satisfactory results are not likely to be obtained, the Contracting Officer may, at his own discretion, stop any phase of the work. The work shall be resumed only when, in the opinion of the Contracting Officer, the desired results are likely to be obtained. All turfing operations shall be conducted across the slope. Establishment of turf shall be accomplished on all unpaved, graded, and disturbed areas that are the result of the Contractor's operations and as specified herein.

5. MAINTENANCE OF TURFING WORK. The Contractor shall maintain all planted areas during the planting period and for an additional period of not less than 120 calendar days following the final acceptance of an acceptable stand of turf, but no earlier than 120 calendar days following the completion of PLANTING SEASON and/or replanting operations if required.

Maintenance shall consist of watering, replanting, mowing, maintaining existing grades, and repair of erosion damage.

6. Stand

A stand shall be defined as the planted area achieving a uniform live grass coverage having a density where the total bare spots do not exceed 2 percent of the total turfed area, bare spots are not larger than 6 inches square, and the grass is of a height sufficient to be capable of being mowed as specified in the mowing requirements contained in this contract.

7. Replanting

If, after the typical period a successful germination of a potential stand of grass is not present, the area shall be reseeded prior to the end of the planting season, or within the next 7 days after the 14-day germination period if after the plant season as specified.

8. Maintenance of Grades and Repair of Erosion Damage

It shall be the responsibility of the Contractor to maintain the original grades of the planted turf areas after commencement of planting operations and during the specified maintenance period. Any damage to the finished surface from Contractor's operations shall be promptly repaired.
