Two 30” RCP sewer interceptors ran parallel through the project limits, tying into one 30” MWRA owned andoperated system. The point of tie-in occurred in SMH 102. BSI Engineering, Inc. inspected the aforementioned sanitarysewer system and the eight associated sewer manholes. A site plan can be found attached detailing manhole numbers,location and configuration of the system. All manholes inspected will be referenced using the numbering system providedto BSI engineering found in attached site plan.Investigation Results1. SMH-104 to SMH-105 to SMH-109Utility: 30” RCP Sanitary SewerVideo: Disc 1, Title: Woburn IPLEX SMH 104-109Comments: This pipe inspection was performed upstream due to limited accessibility. Video inspection begins in SMH104 and heads north, travelling through SMH 105 and continuing to SMH 109.The pipe inspected is deemed to be in fullyoperational condition. No cracks, slipped joints or root infiltrations were discovered.Figure 1.0 SMH 105 – Top viewFigure 2.0 – SMH 105 Interior ViewClient: Haley & AldridgeJob # 13-283011/18/2013Page 1 of 4 *623707*SEMS Doc ID 623707

2. SMH-104 to SMH-102Video: Disc 1, Title: Woburn IPLEX SMH 104-102Utility: 30” RCP Sanitary SewerComments: The pipe inspected is the 30” RCP connecting the reading sewer line to the MWRA sewer line. This shortrun connects SMH 104 to SMH 102. A dye test was performed to confirm the connectivity of these two systems.Midway through the pipe a substantial amount of debris was encountered; due to flow levels the debris could not beidentified. The disruption of flow due to the debris can be seen below in figure 4.0.Figure 3.0 – SMH 104 Top ViewNote:DebrisFigure 4.0 – Debris EncounteredTable 1.0 – Notable CCTV Results (SMH 104 - SMH102)Distance:Clock face Orientation:4’6:003.

This inspection travels downstream (South), through SMH 108 and concludes in SMH 110. With the exceptionof possible debris build-up (figure 7.0) the pipe is fully operational. No cracks, slipped joints or root infiltrations werediscovered.Figure 5.0 – SMH 110 Top ViewFigure 6.0 – SMH 102 Top ViewClient: Haley & AldridgeJob # 13-283011/18/2013Page 2 of 4

A buried manhole wasdiscovered approximately 18’ from SMH 106. This structure was survey located by BSI. Minor debris was encountered(figure 10.0); otherwise this section of pipe has no noticeable cracks, slipped joints or root infiltration. The pipe is fullyoperational.Figure 9.0 - SMH 106 – Top ViewFigure 10.0 – Debris encounteredFigure 11.0 – Buried Structure FoundFigure 11.0 – Buried Structure locatedClient: Haley & AldridgeJob # 13-283011/18/2013Page 3 of 4

Certain utilities shown have been traced on the ground using electronic designation techniques.Designation, or electronic utility location, is defined as the surface location of a utility line basedon electronic geophysical prospecting techniques and is approximate in relation to the actuallocation of the possible utility.2. Certain utilities shown have been taken from available record information. These utilities maynot have been verified. (See Note #4 below.)3. All existing designated utilities near proposed construction should be exactly located usingNon-Destructive Air-Vacuum Excavation, if not already located by Air-Vacuum Excavation (SeeQuality Level A above).4. Unless Non-Destructive Air-Vacuum Excavation is utilized at a particular location, BSIE doesnot guarantee the existence or non-existance of utility lines5. At locations, where BSIE is directed to perform Non-Destructive Air-Vacuum Excavation, thetest hole is advanced until a condition of practical refusal for Air-Vacuum Excavation is reachedor hole is advanced to a depth of 8.0' (eight feet). Practical refusal being defined as encounteringa utility, bedrock, water table, large rocks/ cobbles, suspected hazardous materials or a conditionof hole instability.6. Where BSIE is directed to perform Non-Destructive Air-Vacuum Excavation to confirm thenon-existance of utilities, BSIE will only report non-existance of utilities within the visible limitsof the excavation. BSIE is not responsible for ensuring that work by others is performed at thesame location as the Air-Vacuum Excavation Hole.7. Below ground structures unless otherwise depicted are symbolic only.8. Prior to any excavating, BSIE recommends that all utility owners should review this drawingfor accuracy and completeness.SEWER FACILITIESDCCATCH BASIN ROUNDSSEWER MANHOLELDRAIN LEACHING BASINELECTRICAL FACILITIESEHHEMPEC BOXELHSCCCROSS CUTGeneral Project Notes:DHDRILL HOLEIPIRON PIPELPLEAD PLUG W/ BRASS TAC1.
