FAX (978) 774-1885 STRUCTURAL AFFIDAVIT Project: Installation of a Roof Mounted Solar Panel Array System Location: East Mill, North Andover, Massachusetts Owner: RCG LLC Owner's Address: 21 High Street, North Andover, Massachusetts Date: September 10, 2008 As the Structural Engineer -of -Record (SER) for the addition of a roof mounted, solar panel array system at the above referenced project, I hereby acknowledge the following: To the best of my knowledge and belief, the design and construction for the roof mounted Photovoltaic Hardware System has been satisfactorily completed. The additional roof loads imposed by this installation, were investigated and reported by BMC Engineering, in our building at No. 21 High Street Roof Loading Assessment Report, dated June 13, 2008. This report was prepared for our client, NexAmp Inc. and submitted with the Application for a Building Permit to the Town of North Andover. The findings of this report concluded that in the majority of the roof area the additional loads imposed by this installation can be safely supported by the existing roof structure. All structural evaluations were completed in compliance with the provisions of the Massachusetts State Building Code (MBC), Sixth Edition. The PV panels were installed in the areas dictated by the Roof Assessment report. This affidavit does not relieve the Contractor or its subcontractors of the responsibilities and obligations for quality control of the work, for any design work which is included in their scope of services, and in full compliance with the requirements of the Construction Documents. Furthermore, the detection of, or the failure to detect, deficiencies or defects in the work during the construction, does not relieve the Contractor or subcontractors of their responsibility to correct all deficiencies or defects, whether detected or undetected, in all parts of the work, and to otherwise comply with all requirements of the Construction Documents.

PROJECT DESCRIPTION Introduction This Roof Assessment Report has been commissioned by NexAmp Inc., to determine the capacity of the existing structure to support the addition of a roof mounted Photovoltaic (PV) Array System. The proposed roof mounted system is to be located on the roof of the Building at 21 High Street (see attached roof layout plan). The property is currently owned and managed by RCG LLC. Building Description/History The existing Mill was originally known as the Davis & Furber Machine Shop. Located in North Andover's historic Machine Shop Village district, just five minutes from Interstate 495, East Mill includes over 200,000 square feet of brick & beam space set around the existing mill pond. The building is partly occupied with ongoing renovations for use as space for office, retail, or residential use.

SCOPE OF WORK Structural Engineering Evaluations Our scope of work has been defined as three engineering tasks defined herein: Task A -Preliminary Site Visit BMC Engineering conducted a site visit on May 22, 2008, to record data on the existing roof and building construction. No existing as -built construction drawings were available for this building. We also noted other important in-situ conditions, such as the loading from piping and equipment supports hung from beneath the roof structure, any damage or deteriorations to structural members, evidence of structural modifications or repairs, and any other condition that would influence the loading or capacity of the existing roof framing. Task B- Structural Analysis BMC structural engineers conducted a structural analysis to determine the state of stress and deflection for all roof members to be affected by the proposed loading from the PV Array System. This analysis used Allowable Stress Design (ASD) procedures for the analysis of all structural steel members. Task C- Report Preparation This report provides written documentation of our investigations and conclusions regarding the capacity of the roof to support the installation of the proposed PV Array System. All applicable code requirements, design criteria, photo documentation and structural design calculations prepared for this project are included for record. Limitations This report is solely for use by our client, NexAmp Inc., expressly for his purposes in obtaining a Building Permit from the Town of North Andover to erect the proposed PV Array System. It is not to be used by any other party for any other purpose. The inspection of the existing structure is limited to visual observations. No roofing cores were taken to confirm roofing thickness. III. SITE INVESTIGATIONS Existing Structure At the time of the inspection, the existing roof was comprised of EPDM membrane roofing over rigid insulation, hardboard and 3" nominal thickness Tongue & Groove Oak planking. The area where the PV arrays are intended to be installed is over two different structural framing types described as follows: - Roof Structure Type A: The roof framing consists of either 8" wide by 14" deep or 8 1/2" wide by 12" deep timber beams at 8'-0" on center. The beams have a small slope of approximately 3 degrees to form the roof pitch. The beams have a maximum span of 24 feet and are supported at the ends by the exterior brick walls and by either 8" square or 8" diameter timber columns at interior locations. The overall distance between the load-bearing brick walls is 48 feet. The posts span from floor in this multi story building. The Tongue & Groove Oak Roof Loading Assessment June 2008 Page 4 of 11 planking spans from beam to beam in the east -west direction. The approximate building plan area is 50 feet by 450 feet. Approximately one third of this roof structure has a Clerestory above, located over the ridge line. The clerestory is 10 feet wide with lights on each side. Roof Structure Type B: A smaller portion of the total PV arrays will be installed on this roof structure. The roof framing consists of 18" deep structural steel "I" beams at 8'-0" on center. The beams have no slope; however the roof insulation is tapered to form the roof pitch. The beams have a clear span of 40 feet and are supported at the ends by the exterior brick walls and by 9" square timber columns at interior locations. There is a 2 foot beam cantilever over the posts. The Tongue & Groove Oak planking spans from beam to beam in the north - south direction. According to the NexAmp Inc., the PV Array System will be installed as indicated on the attached roof layout plan. This report is limited to those areas. Conditions/Observations At the time of the inspection the air temperature was approximately 70°F and it was sunny. In the proposed area to be used for the PV Array System, no visible signs of water damage or degradation were observed on the underside of the roof framing members. The timber and steel framing appeared to be performing adequately with no signs of excessive deflection. The EPDM roofing had no visible signs of degradation and all roof drains appeared to be working adequately. No signs of significant ponding were visible on the roof. It should be noted that there is no need for a backup drainage system or a secondary drainage system as failure of the primary drainage systems (i.e. the roof drains) will not lead to ponding as there are no parapets on the roof and water will drain over the eaves of the building. IV. STRUCTURAL ANALYSIS Design Criteria Massachusetts State Building Code 780CMR, Chapter 16 and 34 American Institute of Steel Construction, AISC, ASD Manual, 9th edition Timber Design - National Design Specifications; ANSI/AF&PA NDS -1997 Roof Loadings The Existing dead loads for the roof were calculated based on the Weights of Building Materials Table in the ASD Manual, page 6-9 as well as reference data from specific manufacturers. A Hung load of 3 pounds per square foot was estimated based on the expected ductwork, lighting and electrical components that will be installed when the building is renovated and changed into condominiums. A snow load of 30 pounds per square foot was used based on the Massachusetts State Building Code 780CMR, Chapter 16, Figure 1610.1B, Zone 2. According to NexAmp, the Proposed PV Array System load is 7 pounds per square foot in the immediate area under the panels at Roof Structure Type A and 5 PSF at Roof Structure Type B. Roof Loading Assessment June 2008 Page 5 of 11 Stresses & Deflections All roof framing members in the proposed PV Array area were analyzed for all existing loads together with the proposed new loads. The results of the analysis are included in Appendix B attached. The timber used at the time of construction is assumed to have equivalent properties to "Northern Red Oak No. 1" with an allowable bending stress of 1,350 psi for beams and 1,000 psi for decking. Young's modulus is assumed to be 1,300,000 psi for the rafters, beams and the planking. The allowable stress for the wrought iron beams is assumed to be 12 ksi. The analysis uses loads in accordance with the current building code and was checked against the timber stresses indicated above. V. FINDINGS/CONCLUSIONS The addition of the Solar Collector Racking System caused the roof loads to increase by approx. 11% in the immediate area under the arrays. All timber planking was found to be adequate for the additional loads. In Roof Structure Type A, the 8" wide by 14" deep timber beams were found to adequately support the proposed new loads for both stress and deflection. The 8 1/2" wide by 12" deep timber beams were found to be overstressed under the proposed additional loads and PV modules will not be located in areas supported by the 12" deep beams. In Roof Structure Type B, the 18" deep wrought iron beams were found to adequately support the proposed new loads for both stress and deflection. Based on the structural analysis carried out and based on the loading information and locations provided by the client, the existing roof and roof framing can safely carry the additional PV Array System loads.
