3 1.0 Introduction TELUS Communications Inc. ( TELUS ) has provided this document as a procedural and technical guide outlining the standards and methods required to deliver Voice, Data, and Television services to new Greenfield subdivisions within Alberta. This guideline is intended for use by: a) Joint Use Build Partners - Power, Gas, CATV b) Land Developers & Consultants c) Land Owners d) Municipalities Every effort has been made to keep the document as generic as possible. Local conditions in certain geographical locations may force a deviation from these standards; therefore, this document is to be used as a guideline only. TELUS is a federally regulated company governed by the rules and regulations set forth by the Canadian Electrical Code (CEC), Canadian Standards Association (CSA), Workers Compensation Board (WCB), Human Resources & Skills Development Canada (HRSDC) and the Canadian Radio-Television & Telecommunications Commission (CRTC). For specific geographical considerations or detailed CEC Electrical code requirements not covered in this document please contact your local TELUS Planning, Design Technicians, or Electrical Coordination personnel listed in the directory at the end of this document. TELUS recognizes that with ongoing technological advancement the standards for provisioning of service to new communities must be periodically reviewed. Suggestions for improvements are welcome at all times. Please forward comments or suggestions to ATOPS@telus.com or by calling (ATOP). Thank you from TELUS Page 3 of

4 2.0 Pre Planning TELUS requires specific detailed information from the land developers, and/or their engineering consultants in order to initiate the planning and engineering for placement of communications infrastructure. This information is common to all types of developments: 1. Residential Subdivision Developments 2. Multi Family a) Condominiums b) Row Housing c) Townhomes d) Trailer Parks 3. Commercial 4. Retail 3.0 Required Information TELUS requires information with a high degree of accuracy and detail as all information is placed on a global Geo Imaged based system. The information supplied by the developer and/or their consultant must therefore provide exact location information and other details for the tract of land to be serviced, approximations are not acceptable. Specifically, TELUS requires the following: 1. Tentative legal plan 2. Lot / unit / building civic addressing 3. Tentative deep utility placement including sidewalk, storm, sanitary, and water 4. A digital copy of the computer base plan in Micro-station (.DGN) format 5. The tentative construction schedule TELUS understands that (at the time of initial submission) it is common that some of the required information may not be available. Given this, it is critical that the land developer and their representatives engage in an ongoing dialogue and information exchange with the local TELUS area planner and Design Technician so that advance work can proceed based on detail in hand. It must, however, be understood that TELUS cannot finalize any design or start construction without all of the information in items 1-5 above. Please forward all applicable information to: Real-Estate Ave, Floor 01 Surrey, BC V3S 1X9 Tel: real.estate@telus.com Page 4 of

5 4.0 Shallow Utilities - Three or Four Party Joint Use Build In most geographical regions TELUS has build agreements with the other shallow utilities including Power (local power supplier), Natural Gas (local gas supplier) and Cable Television. The Joint Use design and build program is a mutually beneficial arrangement for all participants which is heavily dependent on collaboration and open communication to ensure a fair and equitable outcome for all utilities. Each geographical area generally has a Joint Use Committee with representation from all participants. TELUS requires a complete understanding of where Power facilities will be placed within the development and will not complete any design work without detailed drawings from the responsible Power supplier. Gas and CATV easements, placements, and servicing models are also a key consideration and must be known to TELUS. The coordination of Power and Communications facilities placement is, however, arguably the most critical aspect of subdivision servicing due to pad placement requirements, loop length criteria and stringent electrical code considerations which ensure safety. Upon receipt of the Power design, TELUS will complete its detailed design and submit for review and consideration by the developer and/or their consultant as well as the other Joint Use partners. This ensures that planned placement of TELUS facilities will not hinder, obstruct or impede any other shallow utility from placing their infrastructure in the development. At this stage, adjustments in design by TELUS and its build partners can be made to resolve any conflicts and ensure an equitable resolution. Detailed information pertaining to TELUS requirements will be covered in the remainder of this document. 4.1 Trenching Considerations Three (3) or four (4) Party trenching is defined as a common trench utilized by three (3) or four (4) individual utilities, for the common purpose of distributing their services throughout a residential subdivision. Regardless of participants, adherence to specific standards ensures that reliable, maintainable infrastructure is built by the participating entities: 1. 3 Party - Power, TELUS, and CATV 2. 4 Party - Power, TELUS, CATV, and Natural Gas The location, number and arrangement of conduits, service boxes, service vaults, manholes and other structures will be identified by the individual utility and communicated to the other utility companies to avoid interference with the placement or arrangement of any other structure, cable, or service junction point. Trenching requirements for TELUS are as follows: 1. Minimum Trench depth must be at least 1 meter (39 ). 2. Minimum coverage of any and all conduit or cable must be 900mm mm layer of sand will be placed in the bottom of the trench to act as padding mm, 50mm and/or 38mm conduit will be placed in the bottom of the Joint Use trench. 5. A minimum of 50mm sand padding must be placed on top of the conduit, before 20mm service conduit, Power, CATV and Gas services. 6. A 100mm layer of sand coverage must be placed on top of the 20mm service conduit, Power, CATV and Gas services before native soils are placed. 7. In four (4) party applications, a minimum of 300mm separation between TELUS Communications and Gas must be maintained. Page 5 of

7 5.0 Residential Subdivision Servicing TELUS incorporates three (3) distinctive methods of facility placement: 1. Conduit based Support Structure: Main-way feeder routes MDU, Commercial, and Retail Post 2009 Residential Greenfield Subdivision Servicing in Alberta s primary and secondary cities and towns o Airdrie, Beaumont, Calgary, Cochrane, Devon, Edmonton, Fort MacMurray, Fort Saskatchewan, Grande Prairie, Leduc, Lethbridge, Medicine Hat, Morinville, Okotoks, Red Deer, Sherwood Park, Spruce Grove, St. Albert, Stony Plain, Strathmore 2. Direct Buried Residential subdivision servicing in smaller towns Pre 2010 Residential Subdivision Servicing in primary and secondary cities and towns 3. Aerial Residential subdivision servicing in smaller towns, (Third Party Applicant) Commercial, Industrial Business Parks Conduit Based Support Structure Feeder and Distribution Figure 2 Typical Residential Subdivision Page 7 of

8 5.1 Feeder A Main-way feeder support structure is required to provide a continuous raceway from TELUS Central Office (CO) to its Distribution Servicing Area (DSA) locations. These structures are either: mm (4 ) EB1 conduit, encased in concrete located within the road allowance. All compaction in this installation will meet or exceed 98% Proctor density mm (4 ) DB2 or HDPE located within the Boulevard. If trenching is required all compaction in this installation will meet or exceed 95% Proctor density. Where conduit is directionally bored compaction is not required. 3. Typically these structures are located along primary traffic arteries in and out of the communities Temporary Feeder TELUS provides permanent feeder at no cost to the developer provided TELUS Design Technicians can establish permanent routing to the subject lands. Road improvements must be to grade, with deep utilities in place before TELUS will build permanent conduit structures to new developments. If TELUS cannot establish a permanent feeder route into the new development, a temporary feeder facility may need to be placed. Costs for the installation and subsequent removal of temporary infrastructure will be negotiated with the Developer. All agreed to costs will be paid in advance. Once a temporary facility is in place, modifications and or rearrangements to this facility caused by construction associated with the developing the subject lands will be at the developer s cost. Careful attention must be given to temporary facility routing to mitigate unnecessary costs. Vertical ground clearance must be maintained (assuming aerial cable is placed) therefore grade changes should be taken into consideration early on in the planning stage of temporary. 5.2 Telecommunication Easement ( TC ) The feeder conduit structure will service a registered Telecommunication Easement ( TC ). Depending on the equipment required these easements will vary in size between 3m x 3m to 5m x 7m and the space generally negotiated with the land developers engineering consultant.. The developer will grant the easement rights to TELUS. TELUS will then register these sites with the provincial land titles office and will place a caveat against the land title to ensure the space is not allocated for other use. An easement will also be required over common property of strata developments. The TC Easement will be strategically placed within a new subdivision and will host the required Digital Cabinets (DLC / DSLAM) and/or Fibre Distribution Hubs (FDH). In some instances, a Walk in Cabinet (WIC) may be required. WIC s are used as a remote hub site where we will be a servicing larger subdivision with a higher than normal residential density and, local commercial and retail sites. 5.3 Single Family Dwellings (SFD) Greenfield subdivision located in the cities and towns identified in Section 5.0 will be support structured based. The residential subdivision servicing is broken down into 5 distinctive parts: (Figure 2) 1. Primary Distribution - (TC Easement to Service Vault) 2. Service Vault 3. Secondary Distribution - Service Vault to Pedestal 4. Lot Servicing Pedestal to Property Line 5. Home servicing Property Line to Home Page 8 of

9 5.3.1 Primary Distribution 100mm (4 ) DB2 duct is placed in the Joint Use trench and will feed from the TC Easement to strategically placed service vaults located approximately 300 meters apart. This duct structure is utilized as a raceway to support our primary distribution fibre and copper cables that feed throughout the residential community. These cables are larger in size and feed directly back to our Digital Cabinet or FDH. The fibre cables will generally be between 24 to 288 fibre strand cables whereas the copper will generally be a 200 pair cable Service Vaults The Service Vaults are required as splice points for the fibre and copper (if required) secondary distribution cables and are strategically positioned to feed as many distribution pedestals as possible. TELUS has available two sizes that may be deployed depending on design requirements x 1016 x 914mm (40 L x 40 W x 36 D) x 1032 x 914mm (64.5 L x 40.5 W x 36 D) The Service Vault Specifications are as follows: a. Material: Polymer concrete b. Bottomless c. Lid: non skid with TELUS logo and locator d. Loading e. ANSI Tier 15 (15,000lbs) static load of 22,000lbs) f. Weight g. Vault 293kg (646lbs) h. Lid (2 pieces):160kg (353lbs), 80kg (176lbs) per side i. Grounded as per CSA Specifications Page 9 of

13 Figure 7 Ground Rod and # Secondary Distribution 38mm (1 ½ ) HDPE Ribbed continuous orange conduit is placed from the service vault to the TELUS pedestal locations via the Joint Use trench. The TELUS pedestals are placed at the same location as the power transformer and the CATV pedestal. This conduit is utilized as a raceway to support our secondary distribution fibre and copper cables. 1. Distance from service vault will be approximately 150 meters. If the duct route is relatively straight this distance may be increased up to 200 meters if required. 2. Each pedestal location will feed directly back to a service vault location and does not route from pedestal to pedestal. 3. In areas where Joint Use pedestals are not incorporated TELUS pedestals will be a MAH 1212 pedestal x 12 at the base and approximately 42 from fill line to the top of the lid (Figure 3). 5. In areas where a Joint Use pedestal is incorporated the same duct layout will apply. Page 13 of

14 Figure 8 MAH Lot Servicing - Pedestal to Property Line 20mm conduit will be placed from the pedestal location to the property line via the Joint Use trench and will be capped and tagged in the service box (service connection point). This conduit is utilized as a raceway to support our fibre and copper service drops. Fibre drops will be a 2 strand fibre dielectric cable and the copper will be a 2 pair 24 gauge. TELUS service conduit is orange in color and is marked every ½ meter with the company name and meter mark. The main distinction between TELUS and CATV duct is the ribbing inside the conduit. The 20mm stub will be capped and tagged with a contact number for the builder, excavator, or electrician to contact TELUS to have the conduit extended. Page 14 of

15 Figure 9 Service Connection Point In instances where the distance from the pedestal to the property line exceeds 90m and there are considerable bends TELUS may place a small Pull Box (PB) as an intermediate pull point. The PB specifications are as follows: Material: Fiberglass Dimensions o Outside 35.9 in L x 24 in W x 34.6 in D (914 x 610 x 880mm) o Inside: 35.9 in L x 22.4 in W x 36 in D (870 x 568 x 880mm) Bottom: Slots in bottom 6 inches x 12 inches wide Lid: Non skid with TELUS logo and locator Locking: Screw slots for locking Loading: 20,000lbs rolling load Weight: o Box 31kg (68lbs) o Lid 32kg (polymer-concrete) 70lbs Backfill to final Grade Page 15 of

17 5.3.5 Home Servicing - Property Line to home- Excavation, Foundation & Service Trench In newly constructed phased developments, TELUS will provide a 20mm (3/4 ) HDPE ribbed conduit stubbed at the property line. Upon excavation of the service connection point and associated trench TELUS will, at its cost and within 72 hrs, extend the 20mm conduit to the service entrance location at the side of the home. Builders are to contact TELUS to have this done by calling , or at @telus.com. Upon the builder contacting TELUS, our contractor will, free of charge, be dispatched within 72 hours. A continuous section of HDPE (High Density Poly Ethylene) SDR 13.5 ribbed orange service conduit will be extended to the side of the house. At the base of the foundation the HDPE will be fed through a TELUS supplied rigid sweeping 90 degree bend and extend up through the builder provided 1 ¼ rigid schedule 40 conduit to a height above the foundation wall. The internal HDPE pipe will be capped and the rope tied off Builder Requirements In order to accommodate the service drop or 20mm conduit, it is requested that the Builder/Owner do the following: 1. Provide a suitable pathway trench as specified by TELUS from the property line to the service entrance location at the side of the home. 2. The service trench is required to be free of all construction materials at a minimum depth of 900mm. Where communications and power service conductors are to be buried in a common trench, the jointly agreed upon joint use standards shall apply. 3. Where there is a grade change, the service trench is required to be sloped (Not Stepped) to avoid any pinching or constriction of the service conduit. 4. Supply and install a 1 ¼ STB and a 1 ¼ Schedule 40 conduit to a minimum of 300mm below finished grade. The 1 ¼ opening on the top of the STB must be capped. 5. On the side of the house a horizontal separation between Electrical and TELUS conduits must be a minimum 8" (200mm) and in addition a horizontal separation between TELUS and Cable TV must be a minimum 10" (250mm) apart. This will allow termination boxes to be placed at same height above grade and maintain box separation. 6. Upon excavation of the service trench the builder will notify TELUS by calling (no Area Code required, Toll Free). The service conduit will be extended within 72 hours free of charge (see Figure 1). The trench is not to be backfilled until conduit extension has been completed. 7. The TELUS contractor will extend the 20mm conduit up through the provided Schedule 40 and STB. In the event that the TELUS contractor completes the install prior to the home builder's installation of the Schedule 40 the builder will slide the 1 1/4' over the 20mm conduit leaving the top of the 20mm conduit accessible in the STB. 8. Before backfill ensure the service trench is free of construction material and the service conduit is placed so that kinking or pinching will be avoided. Only native loose pack fill is to be placed directly on the service conduit (avoid large rocks or frozen soil). Ensure there is 500mm of fill coverage before tamping - Do Not Tamp within 500mm of the conduit. Page 17 of

18 Figure 11 Property Line to Home *Depth of Trench and Minimum coverage may vary from region to region 6.0 Multi Dwelling Units (MDU) In new subdivisions there are several different types and styles of MDU projects requiring specific considerations. Depending on the type and style of the MDU property, TELUS reserves the right to provision the building as it sees fit. TELUS considers size, type and style: 1. High-Rise Or Large Condominium (over 48 units) 2. Townhouse or Row Housing (any size) 3. Bareland Strata vs. Registered Ownership 4. Number of Living Units 5. Attached Retail Page 18 of

19 6.1 High-Rise Developments Over 48 Units For developments exceeding 48 units within one (1) common building, i.e. High-Rise, Condominium etc., TELUS requires an unrestricted and continuous 100mm DB2 conduit raceway from the property line to the building's Main Equipment Room (MER). Upon acceptance from TELUS that an adequate raceway has been provided, TELUS will at their cost provide the distribution cable from the property line into the Main Equipment Room. The main distribution will be Fibre Optics; however the internal technological architecture, (ergo in-house wiring) will be decided at the consultation stage with the Owner / Developer. TELUS has several options that can be deployed to best serve the buildings requirements: 1. Ethernet To The Suite (ETTS) 2. In Premise Digital Subscriber Line Access Multiplexer (DSLAM) 3. Fibre-To-The-Suite (FTTS) TELUS will require a vertical easement within the MER and vertical riser. The TELUS easement will cover TELUS facilities in the Demarcation room as well as the vertical infrastructure that TELUS places. Adequate space inside the Main Equipment room for these types of buildings is essential, and access to 120vac may be required depending on the type of architecture. For these types of service deployment, it is strongly recommended that contact be made with either TELUS engineering department or a TELUS MDU Quality Assurance manager to discuss which servicing platform is best suited for the individual development. For contact information please refer to the directory at the end of this document. All the aforementioned technological architectures provide similar HSIA, Television and Phone capabilities and will be discussed with the Owner / Developer at time of design. Figure 12 MDU over 48 Units Page 19 of

20 6.2 Single Structure MDU Developments - up to 48 suites within one building For single structure developments up to 48 individual residential units which do not exceed four storeys in height requires an unrestricted and continuous 100mm DB2 conduit raceway from the property line to either the MER or adequate Weatherproof Cabinet (WPC). Upon acceptance from TELUS that an adequate raceway has been provided, TELUS will at their cost provide the distribution cable from the property line into the Main Equipment Room (MER). In new Greenfield subdivisions TELUS will serve these building via Fibre Optic Cables and the method of service delivery will be Fibre-To-The-Suite (FTTS). It is strongly recommended that contact be made with TELUS engineering department or a TELUS PM MDU Building Consultants to discuss the in-building standards required to deliver FTTS. A directory of applicable TELUS personal can be found at the end of this document. Figure 13 MDU Units 6.3 Townhouse or Row Housing (any size) Multi Dwelling Units consisting Townhouse, Row Housing, Condominium or like-styled buildings. TELUS requires either: a. An unrestricted and continuous 50mm or 100mm DB2 conduit HDPE raceway from a builder / developer provided Weather Proof Cabinet (WPC) to the property line (Figure 13a). These buildings will be fed via Fibre Optic Cables. A TELUS easement will be required over common property and on any units that TELUS may pass through to reach subsequent residential units. For example, if TELUS cables run through the basement slab of one unit to get to the next, TELUS will require an easement across the intermediate unit. Page 20 of

21 Figure 14a MDU Row Housing TELUS will consider the following as an adequate replacement to conduit and are examples of BIF that meet the ITU-T-G657 standards: a) Indoor/Outdoor (if any part of the route is below grade) Corning s Rugged ClearCurve 001U3F-A mm diameter, black jacket b) Indoor Pyrsmian s AllteraLink 4.8mm diameter, neutral jacket 0001RKHNTAHJRNF Corning s Rugged ClearCurve 4.8mm diameter, neutral jacket Corning s Rugged ClearCurve 4.8mm diameter, yellow jacket 001U31-A U31-A ***NOTE*** for a complete understanding of in-building wiring that will support TELUS Fibre-To-The- Suite, it is strongly recommended that contact be made with TELUS engineering department or a TELUS PM MDU Building Consultants Page 21 of

22 Figure 14b MDU Row Housing 6.4 Bareland Strata A Bareland Strata is defined as a single piece of private property that has not been divided into individual parcels, sections or properties. The builder / developer is responsible to furnish and install all applicable trenching, conduit, service vaults, pedestals and reasonable access to a Main Equipment Room (MER) or an Adequate Weather Proof Cabinet (WPC). Upon acceptance of the raceway and all of its components TELUS will, at its cost and discretion, provide fibre cabling to the demarcation point contained in the buildings Main Equipment Room or appropriate Weather Proof Cabinet. A TELUS easement will be required over common property. In the event TELUS cables run through the basement of one unit to get to the next, TELUS will require an easement across the intermediate unit(s). Page 22 of

23 Figure 15 Bareland 7.0 Demarcation & In-Home Raceway / Wiring Guidelines for Builders In Home Wiring Requirements to support Fibre-To-The-Home (FTTH): TELUS service entrance point to inside of home: 1.
