October 2015

Special Instructions to Designers  
4.6 – Utilities for University Provided 
Revisions have been thoroughly vetted bu the UPE Tunnel Dept., the AEC Utilities Group and various mech tech teams.

      • Title changed – now addresses all utilities, not just those provide by U-M
      • Minor corrections/ clarification to utility temperatures/ pressures.
      • Minor format corrections on cross-referenced section, changed “Project Coordinator” reference to “Design Manger” etc.
      • Added cross reference to DG 5.9 regarding use of PRVs for back-up.
      • Added requirement for flash tanks on high pressure condensate. Though new in this DG, this requirement was routinely enforced but occasionally overlooked by outside AE’s not familiar with best practice. AS such, we expect this change will actually lower costs because flash tanks will be less likely to be overlooked and added via CCD.
      • Added reference to have AEs check with AEC on required backpressure on pumped condensate. In addressing past condensate pumping issues, A&E developed a flow model of the pumped condensate system throughout the tunnels. By checking with A&E, we can ensure properly sized pumps are installed upfront, thereby lower capital and maintenance costs associated with installing sub-optimal pumps.
      •  Added minor correction to backflow prevention for domestic HW.
      • Reference to a “chilled water tap fee” was removed. While this fee may still apply in some cases, it has not been uniformly applied in the past. We feel its best to negotiate that within AEC, rather than confusing outside AEs. No cost impact.
      • New articles were added on “non-university provided utilities (gas, storm, sewer, water), Utility Corridors and Easements. None of these are expected to directly impact cost, but may reduce redesign delays.
      • Clarifications were added to “metering” article. Little or no cost impact with these changes.

Special Building Areas
DG 5.9 Tunnels
Revisions have been thoroughly vetted bu the UPE Tunnel Dept., the AEC Utilities Group and various mech tech teams.

      • Minor formatting adjustments – no cost impact.
      • Added clarification on design pressure versus operating pressure for LPS and HPS. No cost Impact.
      • Changed design temperature to be used for LPS and HPS during an excursion due to desuperheater failure from 600F to 450F. This is a major change that could have significant cost savings on future tunnel projects, and potentially reduce maintenance costs as well, by eliminating the need for some expansion joints. This change was made after extensive analysis by AEC and UPE.
      • Added guidance on the application and sizing of backup pressure reducing valves. This could provide cost savings on some projects. More importantly, it provides consistent direction to be used for future projects.
      • Added requirement for domestic HW valves to be 316 stainless, rather than 304 stainless. Though this will add additional cost on some tunnel projects, additional cost appears warranted considering continuing corrosion issues associated with City of Ann Arbor water.
      • Changed tunnel ventilation requirements, increasing maximum allowable tunnel temperature to 115F (had been 100F). This change will reduce cost of some future projects. However, several sections of the tunnel system do not even meet this less stringent requirement.

5.10 Gender Inclusive Toilet/ Locker Room

237323  Custom Air Handling Units

Revised to indicate when coil vents and drains are to be extended to the OUTSIDE of the casing, per HVAC MTT. (This revision was approved by the HVAC MTT last year but it was mistakenly not sent for posting.)

265100 Interior Lighting 
We have updated the Interior Lighting Specification (the Interdepartmental Electrical Team has already had an opportunity to review and discuss).  Please upload these to our web site (refer to the PDF and DOCX attachments).

Significant updates include:

      1. Added a “night lights” definition in section 1.2.  Consultants and contractors too often confuse night lights with emergency lights, leading to unnecessary RFIs or improper installations.
      2. Added 1.3 Submittals section and a 1.4 Quality Assurance section.  Some of the quality assurance information was reorganized and moved from “PART 2 – PRODUCTS” of the previous version.  LED binning is a new item to ensure a level of LED color consistency.
      3. Added 1.5 Warranty section.  This is essentially a reorganization of items moved from “PART 2 – PRODUCTS” of the previous version.
      4. Added 2.1.A.1, identifying that DLC, LED Lighting Facts, and ENERGY STAR listings/labels are preferred manufacturers to tie in with the previous PML revision.
      5. In 2.1.C, added a designer note regarding that “throw-away” LED fixtures are not preferred.  In general, this should not be an issue with everyday general LED lighting.  However, accent and specialty LED lighting may often have “throw-away” fixtures specified still.  The general industry tends to find this acceptable yet, as accent and specialty lighting can depreciate to 50% or less light output and still be considered effective for their intended use.  If “throw-away” LED fixtures are specified, the lighting designers should discuss this with the project team to receive approval on a project-by-project basis.
      6. In 2.2, added a designer note stating a preference for T8 lamping over T5 lamping, unless the T5 lamping strategy demonstrates a reduction in overall fixture quantities.
      7. In 2.2.A, revised average fluorescent lamp life from “24,000 hours” to “24,000 hours minimum”.  The lamp market seems to be approaching a cross-over in lamp prices.  If longer life lamps are produced in larger quantities, then perhaps they may eventually become cheaper than 24,000 hour lamps.  Let’s get longer lamp life when market forces allow.
      8. In 2.2.B, added a designer note stating a preference of LED fixtures over compact fluorescent fixtures.  LED fixtures are generally cost-competitive with compact fluorescent types, and they have the added advantages of dimming, instant on, longer life, broader operating temperature range, and color quality.
      9. In 2.3.D, added an LED driver qualification of 85% minimum efficiency.
      10. In 2.3.E, added that dimmable LED drivers should be 0-10V type.

230920 Lab Terminal Air Flow Units & Controls
June 2015: added requirement for valve calibration certificate under submittals, added post submittals article.  improved description of valve operation under 2.3.A to require that characterized valve position be the primary means of achieving air volume setpoint, added that additional or fewer air valves are the RESPONSIBILITY of the contractor to provide if a MANUFACTURER other than the design basis is supplied since flow range v. valve DIAMETER varies between mfr.s, required that +/-5% valve accuracy be over the entire cataloged volumetric operating range of the ltau. Strengthened requirement that LTAU INDICATED air volume not to be adjusted based upon field measurements (Art. 3.2). d. karle per hvac mtt.

caution: analog style ltaus typically not AVAILABLE or used for CURRENT projects so this SPECIFICATION should not normally be used, instead use DDC version (230910).  in the unusual condition that this spec is used, edit carefully to make project specific.

230910 Lab Air Flow Controls-DDC
June 2015: Revised to require reheat coil be provided by lcc, added reheat coil spec. added requirement for valve calibration certificate under submittals, added post submittals article.  improved description of valve operation under 2.3.A to require that characterized valve position be the primary means of achieving air volume setpoint, added that additional or fewer air valves are the RESPONSIBILITY of the contractor to provide if a MANUFACTURER other than the design basis is supplied since flow range v. valve DIAMETER varies between mfr.s, required that +/-5% valve accuracy be over the entire cataloged volumetric operating range of the ltau, required fume hood monitors be provided with a common ALARM silence button since some mfr.s were providing multiple silence buttons.  Revised building automation interface requirements to require phoenix macro server and siemens pxc. Strengthened requirement that LTAU INDICATED air volume not to be adjusted based upon field measurements (Art. 3.2). d. karle per hvac mtt.

Preferred Manufacturers List
Revised Electrical PML.  The following revisions have been made:

      1. Under 261100 Unit Substations, the KWHR/Demand Meters have been revised to Schneider Electric PowerLogic ION8650.  This revision now coordinates with the previous specification revision.
      2. Under 265100 Interior Lighting, we have added requirements to preferred LED lighting manufacturers.  LED fixtures that have a DesignLights Consortium listing, a US Department of Energy “LED Lighting Facts” label, or a US Environmental Protection Agency ENERGY STAR label will be considered as preferred.  These organizations vet the manufacturer data sheets to ensure that LED products live up to their literature.  There are over 143,000 listed or labelled LED lighting fixtures between these three organizations.  By adopting these preferred manufacturers, we hope to slow down the “fly-by-night” LED product offerings.  It is understood that low-volume LED products, such as accent or decorative lighting, may not have these listings or labels, so UM project teams will have to accept them on a case-by-case basis.
      3. Under Section 283100 Fire Detection & Alarm Systems, Notifier fire alarms was added for NCRC buildings and a typo for VESDA was corrected.

Special Building Areas
Revised 5.11 Fire Command Center

The changes in the design guideline are due to the following reasons:

      • Clarified that safety-related equipment in the room shall be on emergency power, not outside equipment like HVAC serving the room.
      • Changed the requirement for a control switch to simultaneously unlock stairway doors except exit discharge doors to the outside that are locked by the card access control system to match the current MBC.
      • Specified the room interior door to be keyed for a BA key and the exterior door to have a card reader and be keyed for a ZE key.
      • Changed “Fire Alarm Control Panel” to “Fire Alarm Control Unit” (FACU) to match the change in fire alarm code language.
      • Added that if the building has emergency responder radio coverage (ERRC), the FACU shall monitor it.
      • Added that if the building has emergency responder radio coverage (ERRC), do not provide a fire department two-way communications system.
      • Clarified the generator “AUTO-RUN” switch shall be maintained contact, not spring return to center.

Revised:  Revise stainless pipe description to allow 316L only for cold domestic and condenser water due to concern with chlorides in city water corroding 304L.

New 230905 Mechanical Systems Controls (Hospital Projects)
New mastespec was based on the campus AEC MS 230900.  We have heavily edited Part 1 and Part 3 of the campus masterspec.  Much of the Part 2 Products section remains the same, with relatively minor additions/ modifications to reflect work specific to UMH.

Here’s a summary of what this new masterspec is allowing us to do:

UMHHC owns and maintains a unified Mechanical Control System (MCS) frontend called Siemens Desigo CC.  This frontend is the single and only frontend used to monitor, control, alarm and trend DDC points reporting from a variety of DDC systems used in UMHHC facilities, including Johnson Controls, Siemens, Honeywell & ASI.

      • The design A/E shall utilize UMHHC’s masterspec MS230905 “Mechanical Systems Controls (Hospital Projects)” for all work on hospital funded projects that are to be maintained and monitored by the UMHHC BMS.  AE shall be responsible for editing this masterspec so that it is job specific.
      • All UMHHC DDC systems, regardless of manufacturer or type, shall report all points back to the Desigo CC frontend.  Proprietary, or vendor specific frontends, are not allowed.
      • The complete control system work shall be split between the Mechanical Systems Controls Contractor (MSCC), the Systems Integrator (SI) and UMH’s Medical Center Information Technology (MCIT) department.  See Masterspec 230905 Mechanical Systems Controls (Hospital Projects), Part 1 section for a detailed description on the division of work.
      • The MSCC shall provide a fully integrated BACnet MCS incorporating electric, pneumatic, and direct digital control (DDC) components for the control and monitoring of heating, ventilating and air conditioning (HVAC) equipment and other related systems.  Controllers shall natively use the most current ANSI/ASHRAE Standard 135 for communications and shall be BTL certified with BTL published PIC statements.
      • UMHHC’s Desigo CC frontend is installed on virtual servers in MCIT’s datacenter.  All communication/ integration to the Desigo CC frontend shall be via BACnet IP over the MCIT layer 3 network.  UMHC’s MCIT department shall be responsible for the design and installation of this primary network.  The AE shall coordinate and clearly show on the contract documents all MCIT data drops to all IP based DDC controllers.
      • UMHHC wishes to maximize the use of its MCIT network for a) communication to the Desigo CC frontend and b) communication between DDC building controllers.  Communication to/ between lower level controllers shall be via a MS/TP secondary field level network (FLN), provided & installed by the Mechanical Systems Controls Contractor (MSCC).
      • The SI shall be responsible for BACnet device and object discovery, point instantiation, alarm & trend definitions and creating of all front end graphics.  The role of Systems Integrator shall be performed by UMH Systems Monitoring staff, or an integration contractor hired by Systems Monitoring.  All contracts for Systems Integration, if needed, shall be at the discretion of UMH Systems Monitoring staff and shall be direct contracts with UMH, external to the construction contract.
      • All products to be used as an integral part of the proposed MCS must be contained on the vendor’s pre-approved parts list (including BTL PIC statements) on file with the UMHHC Facility Planning and Development (FPD) office.
      • The AE shall discuss with the FPD mechanical engineer the approved control manufacturers to list in the project specifications.  The desire it to competitively bid all control projects to the approved control manufacturers listed in specification 230905.  In general, all terminal unit controls (VAV/ CAV boxes, mixing boxes, FCU’s, etc) as well as all brand new stand-alone facility installations shall be competitively bid.  However, UMH wishes to standardize controller manufacturers (and programming, sequence of operation, setpoints, alarming, etc) on critical equipment within a given facility.  Examples of equipment that UMH may wish to sole source includes modifications to chiller plants, heating plants, AHU plants and Operating Room/ Procedure Room terminal controls.

SBA 5.11 Fire Command Center and DG 230900 Mechanical Systems Controls
SBA 5.11 Fire Command Center was revised to clarify certain code requirements for Fire Command Centers that are subject to interpretation, which often results in changes during construction. In particular, the requirements for smoke control panels are now described, as well as the requirements for controlling air distribution systems not related to smoke controls. It is expected that these revisions will reduce costs by avoiding change orders, and because in many cases designers or contractors were including features not required by the code or the U-M AHJ, or were failing to include code requirements such as air distribution system controls for high rises. These revisions were reviewed and approved by the U-M Fire Marshal.

Because revised SBA 5.11 specifies that building controls be used for air distribution system controls (rather than duplicating similar functions in the fire alarm system), DG 230900 Mechanical Systems Controls was revised to describe that requirement, and therefore is also included for approval.

Master Specifications
MS211313 Wet and Dry Pipe Sprinkler Systems
Revisions: Pipe used on dry systems is now specified to be schedule 40 galvanized steel in all sizes. Dry system piping must be installed with the pipe seam above horizontal, must be sloped to drain at all locations and all trapped sections must be equipped with a drain valve. Added spec for dry pipe valve. Minor format fixes and mfr. updates. Revised spec name to wet and dry pipe sprinkler systems. Changes are due to ongoing problems with microbiological corrosion on dry pipe systems. A tracked version is provided for information.

6.0 Technical Sections
DG210000 Fire Protection
As recommended by the Fire Protection/Plumbing Mech. Tech Team:

Due to significant problems with microbiologically induced corrosion (MIC), dry pipe systems are to be specified with schedule 40 galvanized steel pipe in lieu of schedule 10 steel pipe. This does increase the cost of dry systems somewhat, however U-M is having significant leakage problems with dry pipe systems utilizing the thin-walled schedule 10 pipe within a few few years after installation, including incidents at the U-M Museum of Art. Due to the corrosion problems dry pipe systems experience, a thicker wall pipe would now be required. Additionally, galvanized pipe is recommended by FM. This change does not impact wet type sprinkler systems, which are the vast majority of sprinkler systems installed at U-M.

Mains and branch lines are required to be pitched at least 1/2 in. per 10 ft in all locations, regardless if in non-refrigerated areas/areas subject to freezing.

Additionally, antifreeze sprinkler systems are banned due to flammability problems with such systems. The State of Michigan recently banned anti freeze systems.

Formatting improvements were also made to the DG.

  • A number of typos and punctuation errors were corrected throughout.
  • 1.2.F – clarified that written certification is required prior to energization.
  • 1.9.A – clarified the warranty requirements.  These are now in better alignment with our general warranty requirements.
  • 1.9.A.1 – added a reference to the Substantial Completion date.
  • 2.1.F.3 – revised bolt and washer finish to clear zinc.
  • 2.1.K – revised metal barriers to barriers
  • 2.2.D.6 – clarified the connection between fused switch and transformer

  • 2.4.J.1.c – clarified control power transfer circuit language
  • 2.4.K.1 – revised metering mounting height parameter
  • 2.4.K.2.d – clarified current transformers and shorting blocks
  • 2.4.K.3.d – deleted redundant height requirement.
  • 2.4.K.5 – revised kilowatt meter model number (previous model was discontinued)
  • 2.4.K.6.a.4 – added shorting terminal block description
  • 3.1.E – added 1″ chamfered edge to pad.  Deleted leveling channels.
  • 3.1.O and P – added one-inch data conduits for metering and position switches
  • 3.2.C – deleted warranty language (clarified in 1.9.A above)
  • 3.2.D – added written certification requirement
  • 3.2.I – clarified study settings required prior to testing
  • 3.4.D – added language to coordinate training sessions and topics
  • 1.2.A and 1.2.B – deletion of all text related to a “design-build” concept.  There have been a number of internal meetings over the past few months to discuss the “design-build” process.  At this time, the majority of projects allot designers several months to design a fire alarm system, bidders a few weeks to pull numbers together, and then onto construction.  With this process, the electricians are at the mercy of the designers and how well the set is documented, and so they can only bid what they see on the drawings to be competitive.  Instead of a true “design-build” process, we’re really structured as “bid-build”.  Further discussions are anticipated on the overall process, but for now, we are eliminating this text.  It’s not clear that the text added value or savings to projects, just confusion.
  • 1.5.K – added a designer hidden note to meter and document maximum ambient sound levels in renovation projects.  This is a reminder to the designer to properly field verify, with the anticipation of reducing errors/omissions.
  • 1.5.L.1 – added a designer hidden note to include room names on all plans, with offices and multi-person offices differentiated.  This is a reminder to the designer to properly document, with the anticipation of reducing errors/omissions.
  • 1.5.N.2 – added a designer hidden note to identify make and model of existing FACPs in order to determine whether a cross-tie is feasible.  This is a reminder to the designer to properly field verify, with the anticipation of reducing errors/omissions.
  • 2.3 – added a designer hidden note to identify the fire alarm control panel as an “Elevator Recall Control and Supervisory Control Unit” in special circumstances.  This complies with the latest Codes.
  • 2.13 – corrected spelling of “plastic” within designer hidden note.
  • 2.23.A.8 – deleted “2007” from the NFPA 72 reference.  Keeping this one “date neutral” will save on revisions down the road.
  • 2.3.J.1.c – added MonoSystems as an acceptable manufacturer for metallic raceways.
