Title: Project AnalystDated: 12/21/2016

Received Date: 12/21/2016

Question 17.a:

17. In SCE-02, Vol. 9, at pages 15-16, SCE describes how pole replacement projects at various “gates” of the pole replacement process were treated in the queue for reassessment with the updated SPIDACalc version.

a. For each “gate” as described in Table II-6 of the testimony, please provide the number of poles that were at that “gate” as of September 1, 2015.

Response to Question 17.a:

Below is a table that provides the number of poles that were at each gate as of September 1, 2015.

17. In SCE-02, Vol. 9, at pages 15-16, SCE describes how pole replacement projects at various “gates” of the pole replacement process were treated in the queue for reassessment with the updated SPIDACalc version.

b. For each “gate” as described in Table II-6 of the testimony, of the number of poles at the gate as of September 1, 2015, please provide the number of poles that were reassessed with the updated SPIDACalc version after September 1, 2015.

Response to Question 17.b:

Below is a table that provides the number of poles, by gate, that were re-assessed with the updated SPIDACalc version after September 1, 2015. Please note that the number of reassessed poles in Gate 1 is less than the number of poles in Gate 1 shown in the response to TURN-SCE-022 Q17a. This is because poles were removed from scope and no longer needed to be replaced. As a result, they did not require reassessment.

DATA REQUEST SET TURN-SCE-022

To: TURNPrepared by: Debra Brooks

Title: Project ManagerDated: 12/21/2016

Received Date: 12/21/2016

Question 10.e:

10. In SCE-02, Vol. 9, at page 12, SCE states that through an RFP process it determined that SPIDACalc provided the best balance among accuracy, simplicity and conservatism.

e. Please identify by name and title the highest-ranking member of SCE’s management and executive teams that authorized the selection of the SPIDACalc software package. Please also provide all documentation provided to that person for his or her review prior to such authorization.

Response to Question 10.e:

SCE objects to the question to the extent that is is overbroad, as it requests "all documents provided to that person for his or her review prior to such authorization." Attached are the documents presented to management at the final stage of the evaluation process. The following is the list of names and title at the time of the decision of the highest-ranking member of SCE's management and executive teams that authorized the selection of the SPIDA Calc software package: Gregg Kludjian, Director Resource Planning and Performance Management (RPPM); Nestor Martinez, Director Central Design & Field Accounting (CD&FA); Tim Boucher, Acting Director Business Process and Technology Integration (BP&TI); Paul Joseph, Principal Manager BP&TI, Robert Francis LeMoine, Principal Manager T&D Maintenance and Inspection; James Harvey, Manager Transmission Design.

DATA REQUEST SET SED-SCE-Verbal-005

To: SEDPrepared by: Martin Collette

Title: Project ManagerDated: 12/19/2016

Received Date: 12/19/2016

Question 01:

Originator: Wendy Al-Mukdad

1. How was SpidaCalc benchmarked and the underlying calculation identified as being ‘best practice’?

Response to Question 01:

During the Proof of Concept (POC) evaluation effort, Engineering evaluated Power Line Systems (PLS), Osmose and SPIDA software packages. SCE had prior pole loading experience with an Access Database calculation program, but it was limited in its calculation ability for complex pole loading. SCE did not have experience with the specific program inputs and loading methodologies of the proposed software packages. For this reason, the software vendors were asked to present their program analysis for nine pole loading scenarios, and to present detailed hand calculations for comparison to the program results.

The pole loading scenarios selected were a mix of pole types that were representative of pole configurations on the SCE system, as well as a pole loading scenario to analyze the effect of decay. Each software package was scored based on the methodologies of the program, rather than on specific numerical results. The program results from each vendor were not compared to other vendors, as the initial program assumptions were not specified nor uniform (for example, specific pole modulus or load distribution on pole due to guys was not specified). The results of the evaluation indicated that all three programs were technically acceptable for SCE use. The PLS software was the most technically superior software, as it offered the most complete modelling capability and could utilize a non-linear methodology that was the most accurate, although not feasible to recreate with a hand calculation. Osmose and SPIDA had very similar, but acceptable, scores with minor deductions because both were not able to perform H-frame structure analysis and both had to perform secondary calculations with assumed factors to analyze pole buckling. The Osmose program had a slightly lower score than SPIDA because the SPIDA program was thought to have a better fiberglass pole analysis methodology.�

The attachment 'PoLAR_POC_BU_Orientation' summarizes the results after an RFP had been issued, and describes the planned Proof of Concept Evaluation of the three vendors selected. Descriptions of all 22 use cases considered in the RFP process are contained in the spreadsheets in the zip file "02_POC_UC_1_to_22.zip." The attachments, 'Osmose Proposal,' 'PLSi_poc_reports' and 'SPIDA HandCalc 1-9 and Methodology' provide detailed descriptions and results for the nine scenarios selected for more detailed engineering evaluation from each of the three vendors involved in the Proof of Concept Evaluation.

It should be noted that this technical evaluation was one component of the overall evaluation of the alternative software packages.

5 Proof of Concept Examples

5.1 Overview

The overall strategy of the following examples will be to demonstrate the accuracy of the SPIDACalc analysisengine. To achieve this we have attempted to provide hand calculations for structures we feel it is appropriate todo so. Some of these examples do not lend themselves particularly well to hand calculation comparisons primarilybecause of the assumptions that would have to be made to make them solvable. This particularly shows up instructures with more than guy wire. Pole structures, with guy wires present, force the assumption of some loaddistribution between the guy wires. These poles would be examples of over-determined systems. You can notknow how much force goes into each guy wire without taking the boundary conditions and material propertiesinto account, which is exactly what the finite model does. For simple examples with low number of guy wires,some assumptions can be made with reasonable accuracy to approximate the correct answer. However, evenwith simple examples we will see that those assumptions don’t always catch the worst case location of stress inthe pole, or properly account for the interplay of all the material properties, forces applied and geometry of thestructure.

5.2 Assumptions

Unless otherwise specified in any specific ”Proof of Concept” item documentation we have made the followingassumptions:

• The construction grade is A.

• The load case is GO95 Light.

• Final tension will be used.

6.2 Analysis

The first step in the loading percentage calculation is to determine all of the loading components. Because thisexample does not have a guy wire, the transverse forces can be used to find the sum of the moments at the polebase, which can be used along with the vertical forces to determine the maximum stress.

6.2.1 Transverse Loading

The transverse loading on the pole is the wind loading on the wires plus the wind loading on the pole. Theequation for the transverse force on a given wire is given in Equation 13.

Fwire = D ∗ pw ∗ l ∗ np (13)

Where D is the diameter of the wire with ice (ft), pw is the pressure of the wind (lb/ft2), l is the averagelength of the wire spans (ft), and np is the number of phases. In this calculation, the length of the wire isactually half of the span to the next pole, but since this example has an equal span of 100 feet next and previous,the final wire length is 100 feet. Where a line angle is present, the force acted upon by the tension in the wiresis calculated by the simple vector component in Equation 14.

FWireTension = T ∗ sin(θ) (14)

Where T is the wire tension, and θ is the line angle.To calculate the moment from any force take the force and multiply it by the distance from the point of

interest. In this case, the distance is the height from the ground to the attachment point of the wire. The windforce acting on the pole itself is also calculated.

To calculate the moment for the pole, the force on the pole is first calculated. This force is shown in Equation15

Fpole = A ∗ pw (15)

E-30

6 PROOF OF CONCEPT 1

Where A is the side area of the pole. The forces are calculated for the pole and for the wires in Table 1 andare shown in Table 16.

Fpw = 28.49ft.2 ∗ 8lb./ft.2 = 227.952lb.

Fww = 150ft. ∗ 4 ∗ 2.65lb./ft. = 159.2lb. (16)

Where Fpw is force of wind on pole and Fww is the force of wind on wire. Using these calculated transverseforces, the moments from the wires and pole are calculated by multiplying by the distance away from the baseof the pole. The resultant moments are displayed in Table 17. The moment arm of the pole is the height of thecentroid of the trapezoid formed by the side of the pole.

Mp = 227.952lb. ∗ 17.663ft. = 4026.285ft. · lb.Mw = 159.2lb. ∗ 38ft. = 6049.6ft. · lb. (17)

We then do an comparison between this value and that value calculated by SPIDACalc in Table 2.

Table 2: Groundline moment comparisons between SPIDACalc and hand calculations.

SPIDACalc 10076ft. · lb.Hand Calculations 10075.88ft. · lb.

6.2.2 Vertical Loading

The second type of loading to be calculated is the vertical loading component of the structure and its members.The vertical force generated by the wires is given in Equation 18.

Fv = (Vi ∗ ρ+ l ∗ ρlin) ∗ np (18)

For zones where ice is present, Vi is the volume of ice, ρ is the density of ice, and ρlin is the linear density ofthe wire This force is summed for each wire and then added to the weight force of the pole, which is the densityof the pole multiplied by its volume. These values are computed and shown in Table 19.

Fpv = 41.55ft.3 ∗ 31lb/ft.3 = 1288.24lb.

Fwv = 0.1451lb./ft. ∗ 150ft. ∗ 4 = 87.1lb. (19)

6.2.3 Longitudinal Loading

In this example the net longitudinal loading is equal to zero. The longitudinal loading is equal to zero becausethe next and previous spans are equal to each other and in line. However, the longitudinal force is calculatedbased on the tension of the wire and the formula is shown in Equation 20. It should also be noted that becauseof the change in temperature, ice weighting and wind loading on the wire, the tension could change from the

initial stringing tension given in Table 1. These tensions are calculated with an iterative process with well knownequations [3]. These calculations are not used here for simplicity, but are considered more accurate.

Fl = T ∗ cos(θ) (20)

Where T is the load case tension in the wire, and θ is the line angle if it exisits.

6.2.4 Stress Calculation

The stress is calculated in this example from a combination of vertical force and ground line moment. Theequation for stress in an un-guyed pole is found in Equation 21.

6.2.5 Results Comparison

Comparing the above calculated results to the calculated SPIDACalc results is done in Table 3, the safety factorscompare very closely.

DATA REQUEST SET TURN-SCE-022

To: TURNPrepared by: Martin Collette

Title: Principal AdvisorDated: 12/21/2016

Received Date: 12/21/2016

Question 06:

6. In SCE-02, Vol. 9, at page 9, SCE states that it began using SPIDACalc as an enterprise-wide tool in April of 2013, and that in December of 2014 SCE engineering identified some potential improvement areas in SPIDACalc’s safety factor calculation methodology. Please provide a copy of all documents, notes and memoranda, including electronic correspondence, from April of 2013 through December of 2014 that reflect SCE engineering identifying or communicating issues or concerns with SPIDACalc, or otherwise identifying potential improvement areas in SPIDACalc.

Response to Question 06:

SCE objects to the question to the extent that is is overbroad, as it requests "all documents, notes and memoranda" covering SCE's evaluation of the SPIDA Calc tool and software. The systematic evaluation of SPIDA Calc by SCE's Engineering group was carried out between July and December of 2014. SCE's Pole Loading Program employees responsible for conducting this engineering evaluation made reasonable searches of their documents in response to this document request.

As discussed in the testimony (see page 13), SCE planners at times noted that SPIDA Calc called for larger pole sizes than might have been expected to meet minimum safety requirements. However, SCE had also recently implemented higher wind loading specifications and expanded the boundaries of the high-wind areas throughout the service territory, which would have resulted in larger pole sizes. As a result, the concerns initially raised by the planners were not inconsistent with outcomes expected.

Given that the Pole Loading Program was new and extensive, a group consisting of field personnel and program management was set up to discuss the ongoing status of the program. Initial feedback from field personnel indicated SPIDACalc was producing results that, even accounting for the change in wind standards and high-wind areas, still seemed to run counter to historical experience. These were communicated to the Pole Loading Program management. Based on this feedback, it was a decided that an independent engineering analysis of SPIDACalc results would be prudent.

F-1

The independent evaluation was initiated upon the request from Mr. Ken Trainor, Director of the Pole Assessment and Remediation, on June 30, 2014. SCE Engineering prepared a proposal outlining the plan for this independent evaluation with key steps and a tentative schedule along with required resources to perform the independent evaluation. The initial draft plan was issued on July 18, 2014, and it included the following key steps in the initial plan:

1. Identify pole construction types for evaluation§ Select three samples for each of the following type:

i. Tangent pole with equal tensionii. Angle pole (bisector guyed pole)iii. Guyed pole/deadend pole (in-line guyed pole)iv. In-line span guyed polev. H-frame

2. Complete first pass of calculation§ Perform pole loading calculation of 15 samples on SPIDA and PLS Software

using SCE’s standard values/assumptions3. Complete second pass of calculation

§ Conduct field survey and perform pole loading calculation of 15 sample on SPIDA and PLS Software using field surveyed data

4. Complete evaluation and make recommendation.

Please refer to the attachment 'SPIDA Evaluation Proposed Plan 20140718'.

Engineering began the independent (separate and stand-alone effort independent of the Pole Loading Program evaluation of SPIDACalc) in late July 2014, after reaching agreement on the proposed evaluation plan. Along the way the team encountered a number of challenges such as overcoming the learning curve of independent engineers previously not involved in the pole loading program, matching the detailed modeling of the selected pole samples from SPIDA to PLS-CADD and PLS Pole, conversion of field sag measurements to usable tension inputs for modeling the pole samples with field surveyed tensions, the increase in scope on the actual number of poles assessed due to adding poles with queen posts and the need to include adjacent poles to correctly model field conditions, and the increase in scope of involving an outside entity as an additional validation measure in November of 2014. These challenges and scope changes shifted the completion date of this independent evaluation to December of 2014.

The Engineering team presented their findings to the PLP team on December 11, 2014. During the time from late July to early December, two major progress updates were given in September and November of 2014 to the working team of the Pole Loading Program. Please refer to the attachments 'SPIDA Evaluation Progress Updates - 20140908', 'SPIDA Evaluation Progress Updates - 20141120' and 'SPIDA Evaluation Progress Updates - 20141211'. SCE's preliminary research shows that Mr. Ken Trainor was briefed on these findings after the September and November updates to the working team. SCE is in the process of verifying this. Mr. Trainor was aware of the final results of the analysis in December, 2014. SPIDA management was also present at the December meeting and detailed discussion on the necessary changes to SPIDACalc were communicated by SCE to SPIDA.

F-2

Please note that SCE has not conducated a search of all documents, notes, memoranda, and electronic correspondence between April, 2013 and December, 2014 regarding SCE engineering identifying issues, identifying potential improvements, or communicating with SPIDACalc, but is providing the key documents that have resulted in updating SPIDACalc and implementation of the revised pole loading assessment.
