Questions & Answers; PN 3918079; IGLOO DEMO

Can I please receive a copy of the Hazard Assessment survey for Building T-4301 completed by

Tetra Tech in 2018?

o Hazard Assessment survey for Building T-4301 completed by Tetra Tech in 2018. Also see attached from Environmental.

Hazards to be properly abated and disposed include the following:

Caulking, friable, 20 linear feet (LF)

Transite, Friable, 600 square feet (SF)

Window glazing, Friable, 5200 SF

Metal is painted and has Lead-based paint and must be scrapped

Contractor that does demolition must have on-call UXO construction support for munitions avoidance because it is on operational range and was a former munitions burning ground

Please confirm that this is a hub zone set aside o Yes, this is a confirmed small business hub zone set aside.

The SOW appeared to be mistaken. The building descriptions did not match the buildings we were shown in the field. Along with that, some of the building numbers differed from what was in the SOW. Please confirm the underground igloos we were shown today were the buildings to be demo’d o The buildings shown on the site visit are the correct structures, however the OB-001 listed in the SOW is incorrect and should be labeled 1602.

Is all the concrete to be removed from the site o The environmental department would like the concrete to be recycled, it can either be left onsite or removed from the site. (KMB)

Does the dirt have to be hauled off or can it just be mounded and left right where the building once stood o Clean spoil soil not used as part of a project will be retained onsite for future use by the

OHARNG unless identified for removal and off site recycle or disposal in the scope of work/contract. The Contractor is required to transport and stockpile the soil to a location designated by the OHARNG. The Contractor will install erosion and sediment controls and will seed and mulch the soil pile(s). (KMB)

Please confirm what seed mixes are to be used

The following information comes directly from the Environmental Procedures:

o Native seed mixes will be used where suitable and compatible with maintenance requirements. An appropriate turf grass mix will be used for high traffic and high maintenance areas. Annual ryegrass can be added to mixes to provide quick cover. For late season seeding, winter wheat/rye can be added to provide a quick cover.

Contractors will use the approved grass seed mixes listed below or propose alternative seed mixes. The OHARNG Environmental Office must approve all seed mixes. The seed mixes that will be used will be identified in the Storm Water Management, Sediment, and Erosion Controls section of the Environmental Work Plan.

o The following seed is approved for establishment of temporary cover. Species can be mixed if/as necessary for specific application.

o Annual Rye Grass (Lolium multiflorum), broadcast @ 40 lbs/acre, drilled at 30 lbs/acre, mulch with a minimum of 3 bales of straw per 1000 square feet. Use mulch netting or fiber mat on slopes greater than 6%. Grows quickly but of short duration. Good growth during hot summer period.

o Winter Rye (Secale cereal) broadcast @ 112 lbs/acre, drilled at 80 lbs/acre, mulch with a minimum of 3 bales of straw per 1000 square feet. Use mulch netting or fiber mat on slopes greater than 6%. Good for fall seeding. Select a hardy variety.

o Oats (Avena sativa) broadcast @ 80 lbs/acre, drilled at 65 lbs/acre, mulch with a minimum of 3 bales of straw per 1000 square feet. Use mulch netting or fiber mat on slopes greater than 6%. Best for spring seeding. Fall seeding will die when winter sets in.

o 40% Nodding Wild Rye (Elymus canadensis), 40% Virginia wild rye (Elymus virginicus), 15% Partridge Pea (Chamaecrista fasciculata), and 5% Black-eyed Susan (Rudbeckia hirta), broadcast @ 35 lbs/acre, drilled at 25 lbs/acre, mulch with a minimum of 3 bales of straw per 1000 square feet. Add 20 lbs/acre of Annual Rye Grass (Lolium multiflorum) to the broadcast mix and 15 lbs/acre to the drilled mix. Good for areas that will remain unfinished indefinitely.

o 23.5% Nodding Wild Rye (Elymus canadensis), 25% Virginia wild rye (Elymus virginicus), 18.75% Partridge Pea (Chamaecrista fasciculata), 1.5% Black-eyed Susan (Rudbeckia hirta), and 31.25% Little Bluestem (Schizachyrium scoparium), broadcast @ 25 lbs/acre, drilled at 18 lbs/acre), mulch with a minimum of 3 bales of straw per 1000 square feet.

Add 20 lbs/acre of Annual Rye Grass (Lolium multiflorum) to the broadcast mix and 15 lbs/acre to the drilled mix. Good for late season (after 15 September) quick temporary cover.

o The following seed is approved for establishment of permanent cover in areas that are not maintained as turf grass or high foot traffic areas such as range impact areas that are not regularly mowed, roadsides outside of cantonment areas, fence lines outside of cantonment areas, etc. Substitution with similar species is permitted but must be approved by the OHARNG Environmental Office.

o 23.5% Nodding Wild Rye (Elymus canadensis), 25% Virginia wild rye (Elymus virginicus), 22% Little Bluestem (Schizachyrium scoparium), 18.75% Partridge Pea (Chamaecrista fasciculata), 7.75% Thin-leaved Coneflower (Rudbeckia triloba), 1.5% Brown fox sedge

(Carex vulpinoidea), 1.5% Black-eyed Susan (Rudbeckia hirta), broadcast @ 18 lbs/acre, drilled at 12 lbs/acre, mulch with a minimum of 3 bales of straw per 1000 square feet.

Add 20 lbs/acre of Annual Rye Grass (Lolium multiflorum) to the broadcast mix and 15 lbs/acre to the drilled mix. This mix is for use in open areas that receive good sunlight.

o 31% Deertongue (Dichanthelium clandestinum), 25% Virginia wild rye (Elymus virginicus), 25% Nodding Wild Rye (Elymus canadensis), 10% Big Bluestem (Andropogon gerardii), and 9% Side-Oats Grama (Bouteloua curtipendula), broadcast @ 30 lbs/acre, drilled at 20 lbs/acre), mulch with a minimum of 3 bales of straw per 1000 square feet.

Add 20 lbs/acre of Annual Rye Grass (Lolium multiflorum) to the broadcast mix and 15 lbs/acre to the drilled mix. This mix is for use in shaded areas, partial sun, and openings in the forest canopy.

o Areas that are maintained with regular mowing during the growing season and receive heavy foot traffic will be seeded with an appropriate turf grass mix. Such areas include lawns in cantonment areas, parade fields, and range operational control areas (ROCAs).

Turf grass mixes of Kentucky blue grass, fine fescue, and perennial ryegrass using varieties appropriate for the specific application will be identified by the contractor and reviewed and approved by the OHARNG prior to application. Contractors will provide draught resistant varieties in seed mixes. A potential mix and varieties are as follows.

o 40% Kentucky Bluegrass (applicable varieties), 30% Perennial Ryegrasses (applicable varieties), 20% Hard Fescue (applicable varieties), and 10% Creeping Red Fescue icable varieties)

Igloo 1602 contained painted garage doors, painted concrete, and a painted wooden wall down the middle of the structure. Is the paint lead containing, and does CRJMTC have the results from any testing that was done o This is currently out to contract to be assessed. We do not have the results yet. (KMB)

Igloo 1602 also had some contents inside. Is that the responsibility of the contractor to remove o See environmental attachment.

Electric ran into the back of igloo 1602. Is the power dead? And how far are we to demo that line back to o The power is dead demo the line to the limit of disturbance.

What is to be done with the “membrane” called out to be adhered to the concrete on the exterior side buried underneath the dirt?

o Membrane is to be considered hazardous and treated as such.

Page four of the SOW references a Hazard Assessment for Building T-4301 that was completed by Tetra Tech in 2018. It was also suggested that these surveys should be utilized by bidding contractors to identify potential environmental hazards within the buildings that may require proper abatement and disposal during demolition. Can we please have a copy of this Hazard

Assessment?

o See answer to the first question in this RFI.

There is a significant cost-impact between providing UXO support for a "Low Probability Area" to a "Moderate to High Probability Area". Also, there is some ambiguity in the level and type of

UXO support the contractor will be required to provide. Section 3.1.1.1 states that "UXO construction support must be provided by the contractor", while Section 13.3.5 of the

Environmental Supplemental Conditions states "The OHARNG will investigate the discovery and coordinate with the appropriate UXO or Explosive Ordinance Division (EOD) support personnel."

Please clarify the contractor requirements for UXO construction support for this project.

o Low Probability

We would intend to use a 500 gallon trailer-mounted water tank for the demolition. Will there be a water supply point near the location to refill our tank when necessary?

o The government does not supply any water. If water is needed it will need to be brought in.

Should the contractor assume that the earth removed from the top and sides of the Igloos will be reusable for fill or will it need to be disposed of (contaminated) and new fill brought in?

o See environmental attachment.

There is no indication of the final grading of each site. Please clarify the required final grading requirements.

o Contractor to provide positive drainage when closing out the site. Which means to crown off the site to drain into existing drain areas.

Will a work week of four ten-hour days be acceptable for the project?

o Yes

What are the requirements of the Engineering Work Plan?

o Not applicable to this project.

Appendix J of the solicitation did not contain a picture. Is there a map that shows the distance between all project locations that can be made available?

o From the front gate to 1602-1603 is approximately 2.5 miles. Distance from the front gate to D0018 D0019 is approximately 6.5 miles.

Will the sign-in sheet for the September 11th site visit be made available?

o Yes, see attached.

Appendix J of the SOW does not include the mentioned map. Can this be provided so the contractor can locate the correct structures?

o Yes, see above answer.

Article 3 statement of work 3.1.1.1 earth covered magazines section 1 states that UXO construction support must be provided by the contractor during demolition activities and refers the environmental work plan. The environmental work plan states that “low potential” areas require UXO Support to be on call and “High Potential” areas require UXO support to be on-site during all activities. Is this a requirement of the project and if so what is the classification of

“potential” for the work areas?

o Low Probability

Section 3.1.25.1 of the scope of work requires the contractor to provide continuous coverage throughout the duration of the project. Will this coverage person need EM-385, SSHO, and

QC,QA training?

o Not applicable

Demolition of Igloo(s) 1602, 1603, D-0018, and D-0019 Scope of Work Environmental Comments

11 Sep 2018

Below are comments and questions from Tim Morgan, Environmental Supervisor concerning the above project that arose at the pre-bid on 11 Sep 2018. Comments in yellow highlight require answers/input from the OHARNG Camp Ravenna staff and/or project manager and the SOW then needs updated. Non-highlighted comments are ENV clarifications that can go directly to the contractors bidding on the project upon review and approval by our project manager and DPW.

Comments are numbered by SOW section.

1.2.1 Delete “Above Ground Powder Magazine Storage Igloos” and replace with “Earth Covered Magazines”.

The buildings are not above ground magazines.

2.1.1.1 The descriptions of 1602 and 1603 are incorrect. Both buildings are concrete, slab on grade earth covered magazines. They are not above ground magazines. Do not know what OB-001 is and why it is included. Delete it. These are specialty ECMs. 1603 was used to temporarily store donor material and/or material being burned. 1602 was used as a safety and observation shelter during burning operations and as an associated miscellaneous storage area. 1602 is 775 square feet according to the original real property data card. The real property card for 1602 is lost, but it is very small – maybe 10’ x 8’ floor space.

2.1.1.1 (the second 2.1.1.1) D-0018 and D-0019 are not above ground magazines. They are both earth cover magazines. The description that is given in the SOW is for an above ground magazine. Correct it so it accurately describes an ECM. Both are 1808 square feet and both have a 185 square foot concrete platform.

3.1 We have a mediocre hazard assessment for buildings 1602 and 1603. The assessment was done to determine the presence of lead, PCBs, and obvious asbestos, but not in a manner that enables characterization of the waste that will be generated during demolition.

3.1.1.1.1 For 1603 the steel door must be recycled as scrap metal. The paint on the steel door does contain lead. Recycle all metal as scrap metal. There is no asbestos or other hazards. No additional characterization / survey required.

We have a few plastic trash cans and pallets in 1603. These are owned by the OHARNG and need to be removed by Camp Ravenna prior to demo.

For 1602.

There are several old rusted drums and miscellaneous other item in the storage half of 1602. A fiber drum is marked contaminated. These items were associated with munitions open burning operations. These items need to be examined and removed by the OHARNG verses a demolition contractor prior to demolition.

1. Asbestos - There is 17 square feet of transite cement board around the garage door that must be abated.

The transite is painted with the same paint that’s on the exterior wood doors that is non-detect for PCBs but high in lead, so this needs to be assumed to be a mixed waste (asbestos + lead) for disposal purposes unless the contractor pays to have it further analyzed and characterized to show otherwise. The caulking around the doors (60 LF) was not sampled and analyzed for asbestos in the original survey. Caulking often contains asbestos. The OHARNG pulled a sample on 12 Sep 2018. Results will be available in 2 to 3 weeks. For bidding assume the caulking contains asbestos and must be abated.

2. White Painted Exterior Wood - The white painted exterior wood doors and trim are hazardous waste due to lead in the paint. Remove these and dispose of as lead hazardous waste.

3. Wood Painted Interior Walls - The paint contains both lead and PCBs. The white paint on the interior wood wall is greater than 50 ppm PCB. The lead is probably not high enough to make these walls hazardous waste, but we simply cannot say for certain based on the information we have. So, a core must be taken of the painted wood wall and a TCLP performed for lead to determine it is a hazardous waste due to lead. Assuming the lead is not an issue, dispose of the interior wood wall as PCB bulk product waste in a licensed landfill. This will require a 15-day notification to the landfill prior to shipping. If it is hazardous waste due to the lead, it will need to be disposed of as a mixed waste.

4. Interior Painted Concrete - A couple core samples of the interior painted concrete must be taken and a composite analyzed to determine if it is a hazardous waste due to lead. We do not think it will be but is must be sampled to confirm since the paint does contains lead. The PCB content is less than 50 ppm, so PCBs are not a factor for disposal.

3.1.5 The OHARNG does not have a pre-demolition environmental hazards assessment for D-0018 and D-0019.

We have historical knowledge regarding potential hazards.

We recently discovered that some of the ECM doors are asbestos filled. The doors on D-0018 and D-0019 look to be the type filled with asbestos. The Contractor is to assume the doors contain asbestos and/or may take a core sample to determine if they contain asbestos. The doors cannot be scrapped unless the asbestos is abated. The paint on the doors has not been sampled, but is assumed to contain lead based on samples of similar paint. If not abated and scrapped, the contractor is required to coordinate with the receiving landfill regarding waste characterization and disposal of the doors. The methodology and disposition must be approved by the OHARNG Environmental Office.

3.1.7 There is no basement to fill at the demo sites so how can the concrete be crushed and used on site as fill? We need to specify that the contractor will use enough subsoil covered with a minimum of 6 inches of top soil to provide positive drainage of the work site. For the extra fill at D-0018 and D-0019, we do need fill in a portion of an adjacent railroad bed filled for the construction of the CP/MPFQC. Extra spoil and crushed concrete from D-0018 and D-0019 could be used to fill this railroad bed, but its placement and compaction would need to be to specification – so probably NOT a good idea. The earth fill on the ECM on the MK-19 range, 1602 and 1603, cannot leave the range. We need to specify that the soil from these structures will be separated into top soil and subsoil piles, stabilized with a native grass stand, and left within the demo footprint. Contractors say there is not enough concrete to justify the expense of onsite crushing. Are contractors required to crush on site? If the concrete is hauled off site to be crushed is the contractor required to bring the crushed concrete back on site as seems to be indicated by the SOW – “any that may be left over will be places [sic] on site at a location determined by CRJMTC…”. We need to clarify this. The concrete from 1602 and 1603 can be taken offsite. Proper disposal / reuse of the painted concrete will depend upon analytical results.

Recommended language for the SOW:

The concrete suitable for recycling from both locations will be crushed into aggregate size 1’s. Crushing may be done on or off site. If done onsite, the material will hauled to a designated storage area on Camp Ravenna within 6 miles of the project site. If crushed off site, the contractor will provide the OHARNG with documents showing the concrete was crushed for recycling/reuse. Any contaminated concrete will be hauled off site and properly disposed.

Unexploded Ordinance (UXO) avoidance support is required when disturbing earth on and around 1602 and 1603. The UXO support will comply with existing Camp Ravenna protocols. Contractor activities will be closely coordinated with ongoing USACE operations. Items will be categorized as munitions debris / scrap with no explosive hazard and properly recycled or as items with a potential explosive hazard and blown in place if unsafe to move or taken to the Camp Ravenna buried explosion module (BEM) and detonated. Historically, most items found at Camp Ravenna are scrap or are safe to move.

At all project locations, the contractor will use enough subsoil covered with a minimum of 6 inches of top soil to provide positive drainage of the work site. Positive drainage means a crowned finish that allows drainage into the exiting natural drainage patter.

The soil cover removed from 1602 and 1603 will be segregated into subsoil and top soil and piles, stabilized with a native grass stand, and left within project footprint.

The soil cover removed from D-0018 and D-0019 will be segregated into subsoil and top soil and piles and will be transported to a designated storage area on Camp Ravenna within 6 miles of the project site. The piles will be stabilized with a suitable grass stand.

3.1.8 Same fill comment as 3.1.7.

3.1.10 Same fill comment as 3.1.7.

3.1.13 We have old ENV procedures in this SOW but they will work. I recommend not changing them out.

3.1.15 We need to state that, “The contractor is required to provide positive drainage when closing out the sites, which mean crowned to drain off the site into the surrounding, existing drainage pattern”.

6.2.3 This project should not disturb 1 or more contiguous acres and so a SWP3 and a construction storm water permit should not be needed. If the Contractor makes a mess and disturbs more than 1 acre, both will be required.

6.2.4 As long as less than 1 acre is disturbed, the contract must follow storm water BMPs and a formal E&S plan is not required.

6.2.8 There is a small wetland near D-0019 and within the railroad bed fill for the CP/MPFQC range. The contractor is permitted to fill these wetlands IAW NWP#18. The OHARNG ENV Office has already coordinated this with the USACE and the Ohio EPA.

6.3 See 3.1.1.1.1 discussion regarding waste characterization and management.

6.4.1 See 3.1.1.1.1 discussion regarding asbestos.

6.4.2.2.2 Include asbestos abatement plan in the environmental work plan.

6.5.2 Include lead abatement plan in the environmental work plan.

6.6.1.3 Seed the D-0018 and D-0019 sites with an OHARNG approved drought resistant turf grass mix. Seed the 1602 and 1603 sites with an OHARNG approved native seed mix.
