TG 08710 v06.08

Summary of Changes:

 

Portions of the specifer instructions have changed and a specification section has been added.

 

Reason For Changes:  

 

·        Tech Guide provided because a local vendor complained that consultants are providing specifications with features which are proprietary, then disapproving substitution requests for competing vendor’s door hardware which does not have the same features or were made of anodized aluminum in-lieu of the specified stainless steel.

·        Specifies the acceptable brands/model of door hardware to DAGS. Products which are equal or better than the specified brands/models will be    considered for substitution after the contract award. For the top tier locks we have specified Sargent, Schlage and Best.

·        The Consultant is instructed to:

o       Avoid listing hardware make/model with features which are proprietary or limit competition. Examples are requiring door closers with pressure relief valves or specifying panic exit devices made of anodized aluminum as unacceptable.

o       Avoid requiring the consultant to justify reasons for disapproving door hardware substitution request.

o       Confirm that door hardware specifications are not proprietary by consulting with door hardware vendors and manufacturer representatives. Ensure the specified door hardware devices can be competitively supplied by at least 2 local vendors.

·        We require specifications include:

o       Manufacturer’s standard warranties for their top tier door hardware:

§         Locks 5 years

§         Door Closers 10 years

§         Panic Exit Devices 5 years.

·        Defective hardware, including manufacturer warranted hardware, shall be replaced within 36 hours after notification.

·        Existing Sargent lock master keying cannot be matched by Schlage locks. To increase competition, we are allowing the contractor the option to replace existing Sargent cylinders to match the type of new locks being provided, thereby obtaining a new master key system.

 

 

Changes in TG 08710 Finish Hardware, noted below:

 

 

1.         COORDINATION ISSUES:

 

1.1        Coordinate finish hardware with other technical sections, details, and project requirements.[REF1] 

 

1.2        When disapproval of a finish hardware substitution is necessary, the A/E must provide specific reasons for the disapproval. Obtain DAGS Inspection Branch or District Office concurrence before recommending disapproval of a contractor’s[EL2]  hardware submittal.  If substitutions are allowed disallowed during the bidding, phase immediately provide specific justification reasons for the disapproval to the DAGS Project Management Branch Project Coordinator.

[REF3] 

2.         DESIGN ISSUES:

 

2.1        Problem:

 

2.1.1     The astragals on a double door can conflict with the active leaf lockset strike lip.

 

2.1.2     Overhead door coordinators on double doors with astragals can conflict with the closer housing/mounting plate on either leaf.

 

2.2        Recommendations:

 

2.2.1     In consultation with the specified hardware supplier assure that the strike and closer mounting plate are designed for application to a double door with astragal and coordinator.

 

2.2.2     Avoid the following:          AVOID:[EL4] 

2.2.2.1  Specifying a proprietary hardware manufacturer and model . which is proprietary.  Preferably the product must be provided byd available from by 3 manufacturers [EL5] suppliers, but at least 2.  When this is not possible, get obtain DAGS Project Coordinator’s prior acceptance and approval of what will be a sole source restrictive specification; DAGS to complete SPO Form-14, Request for Restrictive Specification.

 

2.2.2.2  Disapproving the Contractor’s door hardware substitution request when the substitute device is equal or better than the hardware brand and model listed in the contract specifications  [Larry – not sure is something was left off here ]

 

 

2.2.2.3  Limiting competition by listing hardware brands in the specifications which are all owned by the same parent company.  For example: Schlage, Falcon, Monarch, etc brands are owned by Ingersoll Rand.  Sargent, Yale, Corbin Russwin, etc. brands are owned by Assa Abloy.  Ensure hardware competition exists for the listed brands among the local hardware suppliers.

 

2.2.2.4  Providing de-facto proprietary specifications when the existing lockset master keying can only be matched by one lockset brand. (If only one brand can match the existing master key system, notify the Project Coordinator. A proprietary product waiver Approval for a Sole Source procurement  (SPO Form-1)[EL6]  may be required from the State Procurement Officer).

 

2.2.2.5  Requiring salient hardware features which cannot be provided by at least 2 local suppliers.

 

2.2.2.6  Requiring features which are not salient to the device’s function.  The following features are not considered required features:

            a.   Door closers: With or without pressure relief valves.

            b.   Panic exit devices: With all stainless steel or optional aluminum base metal construction.

[REF7] 

[REF8] 

 

2.3        For new projects expected to be constructed in phases, confirm with DAGS Quality Control Branch if any requirements are required for the lock manufacturer of the initial phase to provide unit pricing for future phases.2.3 Proprietary or Restrictive Specifications: To avoid inadvertently specifying proprietary hardware devices, consult with at least 2 of the local hardware manufacturer’s representatives or suppliers to ensure that open competition exists.

[REF9] 

3.         DRAWING NOTES: (Not Used)

 

4.         STANDARD DRAWINGS: (Not Used)

 

5.         SPECIFICATION NOTES:

 

5.1              Due to recurring maintenance and security problems involving door hardware (on both CIP and Repair and Maintenance projects), the consultant shall address the following items in preparing the contract documents:

 

5.2  Existing lockset hardware manufacturer.

 

5.2.1     The manufacturer of the existing lockset shall be listed in the project specifications. Where there is more than one manufacturer's lockset installed at the facility, verify with the DAGS Project Coordinator which manufacturer should be listed for master-keying of new locks.

 

5.23                  Condition of the existing doors, door frames and hardware to remain.

 

5.23.1   Where patching is necessary, patching compounds shall not be used. The patch shall consist of wood plugs secured with permanent adhesives.

 

5.23.2   Where existing hardware is to be retained and installed on new doors, ensure that the hardware is in proper operating condition and are properly installed so that the operation of the door is not adversely affected.

 

5.34                  Hardware:

 

5.34.1   Exterior doors shall have locks classified with free-wheeling levers which are multiple times Grade 1 standardsas Grade 1, "heavy duty" with six-pin tumblers.

 

5.34.2   The latest manufacturer's product data shall be used to ensure that the latest up-to-date models are used. Be sure not to mix-up model numbers between the various manufacturers.

 

5.34.3   Products which are not locally stocked or serviced, or which must be "special ordered" are not acceptable for typical hardware items.

 

5.4.4     Exit device vertical rods shall be one-piece construction. No splicing shall be allowed.[REF10] 

 

5.4.5     Where panic hardware is to be installed on hollow-metal or fiberglass reinforced polyester doors, they shall be mounted with theft resistant through bolts.

 

5.4.6     Clothing can get caught on strikes which excessively protrude from the face of the jamb and they are also easily kicked loose by vandals. Therefore, the type of strike required and its length (center-line of strike to the lip edge) shall be specified.

 

5...34.47     Floor mounted bumpers and stops are easily kicked loose and are a potential tripping hazard. Where door bumpers/stops are used, they should be wall mounted where practical. Where use of floor mounted bumpers is unavoidable address the maintenance and hazard issues in the design and placement of bumpers.

 

5.34.58 Where floor mounted door stops / bumpers are provided, they shall be secured to the substrate using fasteners as noted in Item No. F.3. or stainless steel inserts shall be installed onto which the stop / bumper can be secured to using theft-resistant fasteners. The top plate of the insert shall be flush with the top of the floor finish.

 

5.4  5    Keying:

 

5.45.1         Identify which locks are to be "keyed-alike". (Coordinate requirements with the user through the Pproject Ccoordinator.)

 

5.45.1.1      Multiple doors leading into the same room shall be keyed-alike.

 

5.45.1.2      Secondary rooms within a larger room shall be keyed-alike.

 

5.45.1.3      In matching existing keyways, use of the original manufacturer's cylinders will be required[REF11] . "Off-brand" cylinders or keys shall not be used.

 

5.45.2   Identify which locks are to be keyed separately. (Coordinate requirements with the user through the Pproject Ccoordinator.)

 

5.4.3     Depending on the existing door lock brand, some lock brands cannot match the existing master key.  Therefore, requiring a match of the existing master key system may result in limiting competition.  Seek, if practical, means to open competition by specifying the following on projects where the new keys are an extension of a single key system:

5.4.3.1  Allow the Contractor the option of replacing the cylinders of the existing locksets, at no cost to the State, in order to provide one master key system.  This will allow for more open competition.

[REF12] 

5.6  Installation:

 

5.6.1     Call for a "pre-installation" meeting between the contractor, hardware installer, hardware manufacturer's representative or supplier and the State Contracting Officer to review the hardware installation instructions and installation conditions.

 

5.6.2     Call for the hardware manufacturer's representative or supplier to verify the installation and operation of the hardware prior to final acceptance.

 

5.6.2.1  All keys cut for the project shall be tested to ensure proper operation.

 

5.6.2.2  The manufacturer's representative shall also instruct the user's staff on the hardware's maintenance procedures (type of lubricant needed and frequency of maintenance).

 

5.6.3     Hardware shall be provided with appropriate fasteners properly installed to suit substrate conditions. (e.g. Expansion shields securing hardware such as door stops/holders to concrete or solid grouted masonry substrates should completely fill the depth and diameter of drilled holes. Shimming of the shields or the use of plastic shields is not acceptable.) The fasteners which are provided by the hardware manufacturer as "standard" items should also be checked to ensure this criteria is satisfied.

 

5.6.3.1  Fasteners exposed to the weather shall be of non-ferrous metal or stainless steel.

 

5.6.4     Specify recessed floor strikes.

 

5.57            Substitutions: When evaluating proposed hardware substitutions, make sure that the physical and operational characteristics, construction, performance requirements, etc. of the proposed product is equivalent to or exceeds those of the specified product. Where necessary, request submittal of actual samples so a visual comparison can be made. Examples of items to check are as follows:

 

5.57.1   Diameter of the door stop "stem" supporting the rubber bumper.

 

5.57.2   Accessibility of closer adjustment valves.

 

5.57.3   Thickness and width of closer arms.

 

5.5.4     Thickness of threshold extrusions

 

5.5.5     Contractor’s Substitution Request:  Obtain concurrence from the DAGS Project Coordinator/Contracting Officer prior to recommending disapproval of a door hardware substitution request.

 

5.6        Hardware Types:  The TG specification contains materials typically used in DAGS projects.  Delete items not used in project for which the section will be used.  Add paragraphs for items such as:

5.6.1     Electrified locks and latches.

 

5.6.2     Power-Assist closers.

 

5.6.3     Sliding door hardware.

 

5.6.4     Folding door hardware.

 

5.6.5     Pivots.

 

5.6.6     Closer holder release devices.

 

5.5. ,6.7      Key control systems.

 

5.7.4     Cylindrical door locksets: The manufacturer's of door hardware each have several locksets, of varying quality, which satisfy the ASTM 156.2 Series 1000, Grade 1 criteria established by the Builders Hardware Manufacturer's Association (BHMA). Because of their "varying quality", they cannot all be considered as "equal" products. Therefore, the following locksets will be considered as being "equal":

 

Sargent 10-line = Schlage "D" Series = Yale 5400L = Corbin Russwin CL3400 = Best 9-Line.[REF13] 

 

6.         GUIDE SPECIFICATION: (Not Used)

 

6.6.1          Section 08710 Finish Hardware.
