Project Overview

The intent of the Project is the elimination of the sanitary crossing underneath the runway from IX Center

to NASA.

This shall be accomplished by the installation of a new gravity sanitary sewer from Point A to the south

along the western edge of the western IX Center parking lot. The new sewer would connect to the existing

public gravity sewer along Aerospace Parkway near Point G. The depth of the new gravity sewer will vary

from 10 feet to 20 feet deep along the route as shown in Figure A-8.

The existing sewer system near Point G is owned by the local municipality (The City of Brook Park). This

connection will need to be coordinated with and approved by the City of Brook Park. The capacity of the

existing sanitary sewer NEORSD system on Sheldon Ave may need to be investigated as part of final

design.

Quantities Assumed:

15 @ 6-foot diameter manholes

1200 feet of 8-inch diameter sanitary sewer approximately 15’ deep

3,700 feet of 24-inch diameter gravity sewer installed at a depth ranging from 6-20 feet by open

cut

3 @ connections to existing structures

Flow fill of existing pipes and structures that are called for abandonment. The diameter and lengths

of pipe are 15-inch – 2300 feet, 12-inch – 2900 feet, and 6-inch – 500 feet. The sewer vault

interior dimensions are 50 feet by 10 feet by 6 feet.

Allowances to be included in the proposals, invoicing as needed on a force account ‘time and material’

basis with 15% markup allowed:

1,000 cubic yards of contaminated soils excavation, handling, and disposal, $50,000

All permit fees, $75,000

Unknown utility coordination and restoration, $100,000

Preparation of easement descriptions, $10,000

Scope of Services

1. Pre-design Work

1.1. Survey – The Design-Builder shall perform or acquire a topographic survey that will generally

describe the project area. This survey shall be used as the base-mapping for the sanitary sewer

design drawings. The survey should also show the I-X Center lease limits. As part of the

previously completed study, topographic survey of the receiving sanitary sewer system was

completed and is available with this RFP.

1.2. Geotech – The Design-Builder shall perform or acquire a geotechnical investigation to determine

the characteristics of the soils in the project area. The geotechnical investigation shall be

conducted at six (6) locations along the sewer route as follows:

Page 3: IX Center Sanitary Sewer

1.2.1. 6” diameter soil cores Drilling in Overburden with standard Soil Sampling to a depth of 30

feet

1.2.2. Particle-Size Analysis of Soils in accordance with ASTM C 136 and C 117.

1.2.3. Particle-Size Analysis of Soils (Hydrometer Analysis) in accordance with ASTM D 422.

1.2.4. Natural Moisture Content in accordance with ASTM D 2216 (Method A). Sample obtained

from test pits at a depth of 1.5 feet, unless otherwise specified.

1.2.5. Specific Gravity of Soils in accordance with ASTM D 854.

1.2.6. Liquid Limit, Plastic Limit and Plasticity Index of Soils in accordance with ASTM D 4318

1.2.7. Moisture-Density Relationship of Soils Test in accordance with ASTM D 1557 (Modified

Proctor)

1.3. Flow Monitoring – The Design-Builder shall conduct flow monitoring in the sanitary sewer

downstream of the I-X Center during a peak event chosen by the I-X Center. The results of this

flow monitoring will be used to design the diameter of the new sanitary sewer. Flow monitoring

should be conducted for a period of not less than 36 hours during an event at the I-X Center. The

peak design flow identified during the flow monitoring shall be added to the expected future sewer

flow from new buildings. The sum will be the design flow for the new sewer.

1.4. Soil Constituent Testing – Design-Builder shall enlist a geotechnical firm to test soils every 1000’

along proposed pipe route, depth of testing shall be a minimum 2’ below pipe. Report shall be

submitted to the Owner prior to start of construction.

1.5. Identification of Required Easements – The proposed sewer alignment will likely cross the lease

limits of the I-X Center and may cross other legal property easements. The Design-Builder shall:

1.5.1. Identify any and all entities from which easements will be required to construct the new sewer

1.5.2. Prepare metes-and-bounds descriptions of any and all required easements

1.6. Identification of Potential Utility Conflicts – the Design-Builder shall coordinate with DPC staff

as well as other public and private utility owners to identify potential infrastructure conflicts with

the new sewer. The Design-Builder shall identify the party responsible for any necessary utility

relocations.

2. Permitting – The Design-Builder shall coordinate with all authorities having jurisdiction over the new

sewer project. The Design-Builder shall identify entities, identify fees, prepare applications, submit

applications, revise applications, and secure permits as required to construct the project. The permitting

entities include:

2.1. City of Brook Park

2.2. NorthEast Ohio Regional Sewer District (NEORSD)

2.3. Ohio EPA (PTI, NPDES)

Page 4: IX Center Sanitary Sewer

2.4. City of Cleveland Building and Housing (SWP3 review)

2.5. FAA (Form 7460-1)

2.6. Others as needed

3. Design – the Design-Builder shall prepare design drawings and specifications as needed to construct

the project. Drawings and specifications shall be prepared by an engineer licensed to perform work in

the State of Ohio and stamped and sealed accordingly.

3.1. Sanitary Sewer – a new sanitary sewer shall be designed in general conformance to the sketches

included in this RFP. The new sanitary sewer shall be capable of safely conveying the design flow

described above.

3.1.1. Sewer Infrastructure Requirements – all infrastructure shall meet all applicable codes

3.1.2. Materials – all materials shall meet the applicable codes of the authority having jurisdiction

3.1.3. 10-State Standards – all new infrastructure shall meet or exceed 10-State Standards

3.2. Abandonment of Infrastructure – the Design-Builder shall prepare plans to abandon the existing

sanitary sewer and related infrastructure downstream of the point of connection of the new sewer

and upstream of the first sanitary sewer manhole outside (northwest of) the AOA. It should be

noted that an abandoned structure similar to a septic tank is among this infrastructure. It should

also be noted that the Design-Builder shall prepare a CSPP (See 7.2) prior to entering the AOA.
