    Introduction to Guideline Specifications

    The LPS Guideline Specifications provide general direction to Architects and other Consultants forthe design and specification of District facilities and facility improvements. They also identify forprospective vendors and contractors products and equipment pre-approved for conformance to

    District standards and expectations. They are intended to promote consistent quality and reasonablecontinuity in products, materials, systems and workmanship for all District facilities; they are notintended to limit creative design or functional problem-solving. The Guidelines are not sufficientlycomplete to serve as buildable technical specifications, but any proposed deviation from them willrequire consultation with and acceptance by the LPS Operations and Maintenance Department.Consultants also will be responsible for informing the District of any conflict found between theGuidelines and current codes, standards or best practices.

    Introduction to Model Specifications & Technology Standards

    The LPS Model Specifications provide more detailed definition of District construction standards andprocedures for consultants and contractors, based upon cumulative District experience with facilitydesign, maintenance and operations. Each section is intended to serve as a model for buildabletechnical specifications, typically requiring customization to address conditions, needs andapplications for specific projects at particular facilities through detailed collaboration betweenconsultants and LPS managers, technicians and users. Identification of technical requirements orprohibitions, pre-approved manufacturers, and preferred products or models is intended to optimizelong-term value to the District and its facilities, balancing innovation and competitive first-cost withmanageable standardization and sustainable life-cycle costing.

    The LPS Technology Standards provide definitive goals, design and installation mandates anddetailed specifications for District facilities infrastructure and devices supporting InformationTechnology, Domestic and Emergency Communications, Smoke/Fire Detection and Alarm, and

    Building Access and Security. The Standards identify professional certifications for designengineers, manufacturer certifications for installers, and relevant experience required for both.Proprietary platforms are identified for each major system, along with pre-approved providers ofmutually compatible component devices. Deviation from any provision in these Standards isprohibited except for unique circumstances and only following exhaustive review and sign-off by theLPS Operations and Maintenance Department, Information and Technology Services and/or Securityand Emergency Planning, as appropriate.

     A. Membrane Adhesive:

    1. Sarnacol 2170 - Adhesive shall be applied by roller. Roller applied adhesive shallutilize a solvent resistant ¾” nap roller, spreading the adhesive to insure a smooth,even 100% coverage of the substrate and membrane. Ensure first layer ofSarnacol 2170 is fully dry before second layer is applied to the back of themembrane for proper reactivation. The membrane shall be pressed firmly into the

    adhesive layer with a water-filled, foam-covered lawn roller by frequent rolling intwo directions.

    Notes:a. Do not install when air temperature is within 5º F of dew point. Solvent

    evaporation time increases significantly when temperatures drop.b. No adhesive shall be applied in seam areas. All membrane shall be

    applied in the same manner.

    2. FTR 190 Adhesive - Apply a 100% continuos coat of bonding adhesive to theexposed bottom side of the membrane and a mirrored area of the substrate.a. Adhesive may be applied by roller or spraying. Roller applied adhesive

    shall utilize a solvent resistant ¾” nap roller, spreading the adhesive toinsure a smooth, even 100% coverage of the substrate and membrane.

    Spray applied adhesive must be spread out by roller to insure a smooth,even 100% of the substrate and membrane with no holidays, globs,puddles or similar irregularities.

    b. Allow the adhesive to dry to a point of being tacky, but not stringy to thetouch. Do not allow adhesive to “dry out” completely. 

    c. When sufficiently dry, carefully maneuver the glued portion of themembrane onto the glued substrate surface, avoiding any wrinkles or airpockets.

    d. The membrane shall be pressed firmly into the adhesive layer with awater-filled, foam-covered lawn roller by frequent rolling in two directions.

    e. No adhesive shall be applied to the lap “seam” areas of the membrane. 

    3. Versico - VersiFlex PVC Low-Voc Bonding Adhesive - Application shall becontinuous and uniform, avoiding globs or puddles.

    a. After thorough stirring (min 5 minutes), apply PVC Low-VOC Bonding Adhesive to substrate and membrane using a 9" (229 mm) medium naproller. PVC Low-VOC Bonding Adhesive must be allowed to dry until itdoes not string or stick to a dry finger touch. The membrane and substratewill be dry (non-tacky) to the finger touch. Any coated area which hasbeen exposed to rain should be allowed to dry and then recoated. Do notapply adhesive to splice areas to be hot-air welded.

    b. Roll the membrane onto the adhesive-coated substrate while avoidingwrinkles. Immediately brush down the bonded portion of the sheet with asoft-bristle push broom or a clean dry roller applicator to achievemaximum contact.

    4. Carlisle SureFlex - PVC Low-Voc Bonding Adhesive - Application shall becontinuous and uniform, avoiding globs or puddles.a. After thorough stirring (min 5 minutes), apply PVC Low-VOC Bonding

     Adhesive to substrate and membrane using a 9" (229 mm) medium naproller. PVC Low-VOC Bonding Adhesive must be allowed to dry until itdoes not string or stick to a dry finger touch.

     A. General

    1. All seams shall be hot-air welded. All field seams exceeding 10 feet in length shall

    be welded with an approved automatic welder. Seam overlaps should be 3 incheswide when automatic machine-welding and 4 inches wide when hand-welding,except for certain details.

    2. Welding equipment shall be provided by or approved by the manufacturer. Allmechanics intending to use the equipment shall have successfully completed atraining course provided by the manufacturer Technical Representative prior towelding.

    3. All membrane to be welded shall be clean and dry.

    B. Hand-Welding - Hand-welded seams shall be completed in two stages. Hot-air weldingequipment shall be allowed to warm up for at least one minute prior to welding.

    1. The back edge of the seam shall be welded with a narrow but continuous weld to

    prevent loss of hot air during the final welding.2. The nozzle shall be inserted into the seam at a 45 degree angle to the edge of the

    membrane. Once the proper welding temperature has been reached and themembrane begins to "flow," the hand roller is positioned perpendicular to thenozzle and pressed lightly. For straight seams, the 1½ inch wide nozzle isrecommended for use. For corners and compound connections, the ¾ inch widenozzle shall be used.

    C. Machine Welding

    1. Machine welded seams are achieved by the use of the manufacturer's automaticwelding equipment.

Dedicated circuit house power or a dedicated portable

    generator is recommended. No other equipment shall be operated off thegenerator.

    2. Metal tracks may be used over the deck membrane and under the machinewelder to minimize or eliminate wrinkles.

    D. Quality Control of Welded Seams

    1. The Applicator shall check all welded seams for continuity using a roundedscrewdriver. Visible evidence that welding is proceeding correctly is smoke duringthe welding operation, shiny membrane surfaces, and an uninterrupted flow ofdark grey material from the underside of the top membrane. On-site evaluation ofwelded seams shall be made daily by the Applicator to locations as directed by theOwner's Representative or the manufacturer's representative. One inch widecross-section samples of welded seams shall be taken at least three times a day.Correct welds display failure from shearing of the membrane prior to separation ofthe weld. Each test cut shall be patched by the Applicator at no extra cost to theOwner.

    3.9 MEMBRANE FLASHINGS - All flashings shall be installed concurrently with the roof membrane asthe job progresses.
