19 Lengthy Construction Process
20 Seismic Restraint Code Requirements 2007 CBC, Sec. 1613A (OSHPD) “Earthquake Loads” Based On ASCE 7-05 2006 CBC
21 Niigata Earthquake – October 23, 2004 Sanyo Electric Niigata Semiconductor Fab Plant • Plant damage - $ 177 million USD • Lost inventory - $ 44 million • Restoration - $ 260 million • Business interruption - $ 356 million Total Losses - $ 837 million Financial Impact of Earthquake Damage to Non- Structural Components… “Code Based” vs. “Performance Based” Design •Building Codes for commercial construction are minimums designed to provide Life Safety NOT Business Continuity. •High Value/High Risk (i.e. “Business Critical”) facilities should be designed for Continued Operation following an earthquake.
22 Important Code Terminology COMPONENT: A PART OR ELEMENT OF AN ARCHITECTURAL, ELECTRICAL, MECHANICAL OR STRUCTURAL SYSTEM. SEISMIC DESIGN CATEGORY: A CLASSIFICATION ASSIGNED TO A STRUCTURE BASED ON ITS OCCUPANCY CATEGORY AND THE SEVERITY OF THE DESIGN EARTHQUAKE GROUND MOTION. (RANGE = A THRU F) SDS: 5% DAMPED DESIGN SPECTRAL RESPONSE ACCELERATION AT SHORT PERIODS. DESIGNATED SEISMIC SYSTEM: THE SEISMIC FORCE RESISTING SYSTEM AND THOSE ARCHITECTURAL, ELECTRICAL AND MECHANICAL SYSTEMS OR THEIR COMPONENTS THAT REQUIRE DESIGN IN ACCORDANCE WITH CHAPTER 13 AND FOR WHICH THE COMPONENT IMPORTANCE FACTOR, Ip, IS GREATER THAN ONE. OCCUPANCY CATEGORY: A CATEGORY USED TO DETERMINE STRUCTURAL REQUIREMENTS BASED ON OCCUPANCY. (RANGE = I, II, III, or IV) HAZARDOUS CONTENTS: A MATERIAL THAT IS HIGHLY TOXIC OR POTENTIALLY EXPLOSIVE AND IN SUFFICIENT QUANTITY TO POSE A SIGNIFICANT LIFE-SAFETY THREAT TO THE GENERAL PUBLIC IF AN ANUCONTROLLED RELEASE WERE TO OCCUR. {FURTHER CLARIFICATIONS CAN BE FOUND IN CHAPTER 4 OF THE IBC} 2006 IBC
23 Other Important Terminology… SEISMIC ACCELERATION (ALSO KNOWN AS “G” FORCE): THE FORCE THAT WILL ACT ON A COMPONENT DURING A SEISMIC EVENT. EXPRESSED IN TERMS OF % OF THE COMPONENTS WEIGHT. FORCE LEVELS ARE DETERMINED BY BUILDING CODE FORMULA. (EXAMPLE: EQUIPMENT WEIGHS 10,000 LBS @ 0.5g’s, THE EQUIPMENT MUST BE BRACED/ANCHORED TO RESIST A 5,000 LB FORCE ACTING IN ANY DIRECTION.)
24 2006 IBC
25 Areas of the contiguous US affected by the IBC that now require seismic bracing… Projects outside the areas shown may also require seismic bracing if the project has a “performance” based seismic bracing specification in lieu of a “code” based specification…
26 The design of the seismic bracing and gravity supports is now required to be engineered and part of the construction documents…
27 Section 13.3.1 Seismic Forces (Fp) ASCE 7-05 Fp = 0.4ap x Sds x Wp (1 + 2z/h) Rp/Ip Equation 13.3-1 2006 IBC
28 G-Forces Vary Based Upon Elevation of the Component (Relative to the Roof) within the Structure *Accelerations shown are exaggerated for sample purposes.

30 The outcome of the SDF worksheet provides the resulting Horizontal Force Requirements for each floor or story. SDF Worksheet 2003 IBC
31 Importance Factors (Ip)… 2006 IBC
32 In the IBC… Seismic Forces are Utility Specific In the IBC seismic forces vary based upon: • The elevation of the utility in the structure. • Vibration Isolated vs. Non-Vibration Isolated • Importance factor (Ip) now depends upon the type of service (i.e. Life Safety, Hazardous Material, etc.) • The CONSTRUCTION of the utility plays a much larger role (Welded Pipe vs. Threaded Pipe vs. Cast Iron) • Size Exclusions are now based upon Seismic Design Categories 2006 IBC
33 California Hospital Note… OSHPD requires that all hospitals in the state of California be designed to a Seismic Design Category D.
34 HVAC Duct Exclusions (CA) For Seismic Design Categories A or B: • All components are exempt. For Seismic Design Category C: • Ip=1.0: All components are exempt. • Ip>1.0: Brace all square duct > 6 sq. ft. Brace all round duct > 33” diameter. (CA Only) Brace/Evaluate all equipment. For Categories D, E, & F: • Ip=1.0: Brace all square duct > 6 sq. ft. Brace all round duct > 33” diameter. No bracing is required on equipment <20 lbs that are connected via flexible connections between associated duct, piping, etc… • Ip>1.0: Brace all square duct > 6 sq. ft. Brace all round duct > 33” diameter. (CA Only) Brace/Evaluate all equipment.

36 Electrical Exclusions For Seismic Design Categories A or B: • No Bracing is required. For Seismic Design Category C: • Ip=1.0: No Bracing is required. • Ip>1.0: Brace all conduit > 2-1/2”. Brace all trapezes 10 lbs/lf or greater. For Categories D, E, & F: • Ip=1.0: Brace all conduit > 2-1/2”. Brace all trapezes 10 lbs/lf or greater. Bracing may be excluded from components weighing <20 lbs that are connected via flexible connection between components and associated duct, piping, etc. • Ip>1.0: Brace all conduit > 2-1/2”. Brace all trapezes 10 lbs/lf or greater.
37 Global Exclusions (regardless of trade) For All Design Categories: Utilities 12” from structure do not require bracing so long as they do not develop moments and cannot impact other utilities or the structure. Where Duct Ip>1.0, 12” Rule does not apply!!! In Seismic Design Category D, Where Ip=1.0, Floor Mounted equipment <400 lbs does not require seismic anchorage calculations as long as flexible utility connections are provided. In Seismic Design Category D, Where Ip=1.0, Floor Mounted equipment with legs >4’ tall, regardless of weight, require seismic calculations for both the anchorage and leg (frame) design.
38 The IBC Contains Substantial Changes to Anchorage Requirements… Under the IBC, for Systems Subject to Seismic Requirements… “Expansion anchors shall not be used for mechanical equipment with motors rated over 10 horsepower (7.45 kW). Exception: Use of undercut expansion anchors is permitted.” Spring Isolated Equipment is exempt from this requirement. The Use of Powder Actuated Fasteners is Very Limited (See Table at End of Handout)… 2006 IBC
39 IBC Anchorage Requirements Cont’d… Post Installed Expansion Anchors Must be crack concrete tested and certified by ICC Requires Special Inspection 2 x (or more) expensive than “old” anchors Limited load capacity Drop in anchors not allowed Powers SD1/SD2, Hilti KB-TZ, Simpson Strong-Bolt
40 IBC Special Inspection Requirements Statement of Special Inspections (1704.1.1) – Architect / SEOR / MEP Designer - Permit Phase Statement of Responsibility (1706.1) – Installing Contractor – Prior to Construction Special Inspection (1704) – Hired by Design Team Prior to Construction Component Certification (1708.5) – Equipment Manuf. & Contractor – Prior to Const Quality Control Labels (1707.9) – Contractor, Spec.

50 Is SMACNA Seismic still valid under the IBC? SMACNA Seismic is listed as reference standard in the ’00 and ’03 IBC / ASCE. SMACNA rules and exclusions do not comply with those listed in the ASCE 7-02. SMACNA anchorages do not comply with the cracked concrete requirements of the IBC. All Reference to SMACNA has been removed from the 2006 IBC / ASCE 7-05. 2003/2006 IBC
51 Roles and Responsibilities Owner /Architect / SEOR / MEP Designers (Where Acting as Owners Agents) • Statement of Special Inspections (Permit Phase) • Hire/Provide Inspectors (IOR’s) to Complete Necessary Special Inspections. Structural Engineer…Provide all of the necessary seismic criteria per code requirements. • Document clearly locations of seismic separations on the drawing (preferably a separate drawing), along with designed displacements. • Document clearly (preferably on a separate drawing) anticipated drifts between floors. 2003/2006 IBC
52 Roles and Responsibilities Cont’d… MEP Designers • Statement of Special Inspections • Provide Clear Guidance for Individual MEP System Importance Factors (Ip). (ISAT Can Assist in This Process But Ultimately the System Designer is the Authority on the System) 2003/2006 IBC
53 Example “Statement of Special Inspections” (MEP Ip Schedule):
54 A Final Code Related Note… The IBC requires that the SYSTEM (i.e. HWS, HWR, etc.) be seismically sound. We tend to think within the box of Seismic Bracing for the HORIZONTAL SUSPENDED utilities. In order to fully meet the requirements of the code much more than bracing is required… • Anchor Calcs for equipment. • Riser Supports (both in shafts and at equipment) • Thermal Pipe Stress Analysis • Flex Joints at Equipment or Transitions • Flex Joints at Building Seismic Joints • Vertical Support and Trapeze Engineering • Equipment Certification • Special Inspection Tags • CONTROL OF Vibration Isolation • Seismic Bracing and Vertical Support of Floor Supported Distributed Utilities (i.e. roof mounted duct) • Inspection

57 “THE ISAT PROCESS”
58 ISAT’s involvement can begin during design phase, during construction, or after the utilities have been installed.
59 Step 1: Working with the customer, ISAT’s Technician’s gather jobsite criteria and utility plans.
60 Step 2: ISAT’s Engineering Group calculates the seismic accelerations for the project…
61 Step 3: Consultation & Customer Preferences ISAT consults with the customer to discuss: • Project specific seismic bracing requirements • Project specific seismic impact and constructability issues • Contractor Installation preferences • Construction sequencing to reduce installation labor • Ways to eliminate bracing when possible
62 Step 4: Quote Development Based On the Customer Preferences and Using the Seismic Criteria for the Project, ISAT’s Engineers and Detailers Value Engineer the Project to Determine Minimum Quantities of Material and Engineering Necessary. A Quote For Material And Services Is Then Created…
63 Step 5: Design Coordination ISAT assigns a design team to all major projects consisting of a Project Manager and Project Engineer. Each ISAT Project team then controls all aspects of the ISAT Process from modeling coordination, custom engineering, flex joint and vibration isolation design, material shipments, and inspection.

75 Step 7: A Complete “SB” (Seismic Bracing Drawing Set Is Created For Inclusion In The Project Documents
76 Document Set Includes Trade Specific Seismic Bracing Layouts… Each Seismic Location is Detailed on the Plans and Denoted with a Location Specific I.D. Number A Seismic Bracing Legend is Added to Assist Installers, Inspectors, and Reviewing Engineers in Understanding the Constraints of the Design ISAT’s Structural Engineers “Wet” Stamp Each Layout with Their Stamp from the Project State
77 Example: Cable Bracing Kit Kits Labeled with: -Contractor Name -Project Name -Drawing # -Building Area/Floor Cables are Pre-Tied to custom lengths, field adjustable, with correct brackets installed. (No need to field cut and swage cables, no “hunting” for correct materials) Correct concrete anchors, beam clamps, wood connections, etc. are included in each kit. (No quote surprises, No “hunting” for Anchors) Appropriate quantity of Rod Stiffener components are included in each kit. (No surprises in the quote (stiffeners are usually an add with other systems), No “hunting” for materials) Installation Details are in each kit Step 8: Kit Production and Material Shipment…
78 Example: Rigid Bracing Kit Brackets are Pre- Staked with appropriate Bolts, Washers, and Strut Nuts. (No “hunting” for the right components) Details are utility and seismic location specific. (No need for the installer or reviewer to carry a roll or book of details around) *Brace arm strut is cut to length in the field.
79 Installing ISAT Seismic Bracing… ISAT’s “RCHW” Style Rod Capture Bracket… All of ISAT’s seismic bracing hardware is retrofitable, no disassembly of the utility is required.
80 Buy American Act ISAT’s Seismic Bracing Kits and Blue Banger Hangers, labeled as such, are a “Domestic Construction Material” under FAR 52.225-9 and FAR 52.225-2
81 Advantages of ISAT’s Factory Assembled Custom Seismic Bracing Kits… • Complete installation details • All the correct parts • Lowers installation costs • Speeds up installation • Aids in the inspection process • Eliminates costly rework • Allows the use of lowest cost labor.
82 Prefabricated Supports…

88 OSHPD LESSONS LEARNED Pre-con phase is the most crucial (GIGO!): -Coordinate seismic bracing in complete 3D model -Establish point load impacts -Install high percentage of inserts & work thru halo conflicts -Identify custom supports/bracing early on -Submit RFI’s to clarify project specific interpretations of grey areas (see next sheet) During Construction phase: -Engage IOR/OSHPD early and often : Generate trust -Keep an eye on the GC & Architect with regards to Post-approval designs that have been submitted (DON’T LET THEM SIT ON THEM!) -OSHPD regional crews move slowly and are easily overwhelmed. Keep It Simple and Think within the Box (approved documents/OPA’s) -Documentation Documentation Documentation
89 Grey-area issues: •Set screw couplings – Non-ductile? •Supports/bracing off different structural elements •Flexible connection requirements at all un-braced utility connections •Inherent flexibility of small conduits? •Braced utilities: Install flex after drop or support all the way to connection •Flex at conduit connection to top of switchgear lineups •Code bracing requirements for pull boxes & light fixtures (pull boxes vs. gutters?) •Electrical equipment with raised channels (z clips) & manufacturer end angles (interior and exterior clips) •12” rule and swivel hangers •Biaxial bending at longitudinal seismic locations Contact your local ISAT rep to develop a project specific approach to each grey-area item

100 How Seismic Bracing Can Negatively Impact Your Project… Lack of Technical Support • Coordination Issues will ALWAYS exist, we assign a field engineer to EVERY project. Lack of pre-engineered details • Adds cost for “custom” engineering • Adds delays…time to create custom details and engineering. Inadequate or Inappropriate Submittals • Every Submittal ISAT produces is prepared by an engineer and is specific to the project (No Generic Submittals!) Incorrect Installation • ISAT conducts “Installer Training” on all projects to avoid installation issues. • Pre-Inspection Job Walks to address issues before inspection. Lack of Engineers Stamp • Every submittal we provide is “Wet Stamped” by a Structural Engineer licensed in the state of the project. Complicated Installation Details or Engineering Difficult to Inspect • All Information Necessary for Inspection is provided on EVERY project.

110 THE ISAT SOLUTION (ISAT’s Survey Group) Initial Site Consultation ISAT Site Survey Creation of As-Built Drawings Seismic Bracing Layout ISAT Kits Key ISAT Advantages: Complete Survey of Designated Systems Technical Support Throughout Project QA Tags: Building In Value During The Construction Process Streamlined, Cost-Effective Means of Achieving Code Compliance.
111 Step #1: Initial Site & Client Consultation Consult with owner’s representative to establish project goals. Discuss critical building systems and hazardous utilities. Acquire available drawings and site structural info. Walk facility to discuss general site layout, above ceiling access, and operational concerns. Project specific seismic impact and constructability issues Project Installation Conditions
112 Step #2: ISAT Site Survey ISAT Survey Team to begin work as directed by Owner. Survey Team available during facility “down hours”. Field conditions reviewed to identify congestion issues and bracing solutions. Create or update as-built drawings of MEP utilities. When we do the creation of as built drawings through a survey, we also engineer and place the seismic on those drawings field verifying so it can actually be installed at that location….All in one step. The contractors now have the exact conditions to bid and will not have any grey area that typically forces them to increases their bid. The industry standard approach is for the Architect or MEP Engineers to create the as-built drawings, then they write specs so the bidding contractors have it in their scope to do the seismic. We cut out one whole step and streamline the contractors bid while providing the most effective means of passing through the inspection/local approval gauntlet. By utilizing ISAT we will streamline the cost and mitigate time and installation cost risk.
113 Step#3: Creation and Approval of Seismic Bracing Layouts As-built drawings created in AutoCAD. Field survey information utilized to engineer specific code compliant solutions. ISAT Seismic Bracing layout incorporated into project drawings and wet- stamped by Structural Engineer . ISAT Technical Support interfaces with project inspection staff to facilitate approval.
114 Step #4: Material Quote Development Utilizing the Seismic Bracing Layouts created during the survey, an ISAT technician creates a material quote for contractors to utilize during the bid process.
115 Additional OSHPD Reference Material and Notes
116 Applicability of OPA to 2007 CBC Recent feedback from OSHPD is that they will be enforcing the 2007 CBC sooner rather than later.
117 Don’t get creative, stick to the OPA’s. The biggest delays to OSHPD projects are due to Post Approval issues!!! OPA – OSHPD Pre-approved system: ISAT OPA-0485 (Current expiration dates are not being enforced ). SEOR & MEOR approve seismic layouts and IOR’s inspect. OSHPD DSE reviews to determine accuracy of TDLF (g-force calculation) only . 30 Day Review Period for Post Approvals Post Approval – Non-OPA supports: Deferred Approval – Permit drawings defer items to later date Change Orders – Changes to permit drawings Information Bulletin (IB) & Addendum Custom engineering and detailing with PE stamp submitted and approved by AOR,SEOR,MEOR then AOR fills out PAD form AOR engages OSHPD field crew. DSE either signs PAD and stamps OSHPD approval on detail, or defers to Office Review. Office 30 day turnaround each round of submittal/resubmittal. OPA vs Post Approval
118 OSHPD LESSONS LEARNED Lack of consistency from project to project and different opinions from each field official. Submit RFI’s early to clarify requirements. Examples of currently impacting issues that are inconsistently enforced: Set screw couplings – Non-ductile reduce seismic spacing by ½ Flexible connection from overhead utilities to wall mounted or to floor mounted equipment Detailing and engineering of vertical hangers (non-seismic) “Grey-area” code bracing requirements – pull boxes & VAV’s? No-hub riser joint stabilizers & riser clamp anchorage at each floor Make sure GC and AOR are engaging OSHPD to approve all Post- approval designs upfront OSHPD regional crews move slowly and are easily overwhelmed. Design seismic bracing and all supports early, preferably as part of 100% DD plan set.

Lack of pre-engineered details • Adds cost for “custom” engineering • Adds delays…time to create custom details and engineering. Inadequate or Inappropriate Submittals • Every Submittal ISAT produces is prepared by an engineer and is specific to the project (No Generic Submittals!) Incorrect Installation • ISAT conducts “Installer Training” on all projects to avoid installation issues. • Pre-Inspection Job Walks to address issues before inspection. Lack of Engineers Stamp • Every submittal we provide is “Wet Stamped” by a Structural Engineer licensed in the state of the project. Complicated Installation Details or Engineering Difficult to Inspect • All Information Necessary for Inspection is provided on EVERY project.

    111 Step #1: InitialSite & Client Consultation Consult with owner’s representative to establish project goals. Discuss critical building systems and hazardous utilities. Acquire available drawings and site structural info. Walk facility to discuss general site layout, above ceiling access, and operational concerns. Project specific seismic impact and constructability issues Project Installation Conditions
  • 112.
    112 Step #2: ISATSite Survey ISAT Survey Team to begin work as directed by Owner. Survey Team available during facility “down hours”. Field conditions reviewed to identify congestion issues and bracing solutions. Create or update as-built drawings of MEP utilities. When we do the creation of as built drawings through a survey, we also engineer and place the seismic on those drawings field verifying so it can actually be installed at that location….All in one step. The contractors now have the exact conditions to bid and will not have any grey area that typically forces them to increases their bid. The industry standard approach is for the Architect or MEP Engineers to create the as-built drawings, then they write specs so the bidding contractors have it in their scope to do the seismic. We cut out one whole step and streamline the contractors bid while providing the most effective means of passing through the inspection/local approval gauntlet. By utilizing ISAT we will streamline the cost and mitigate time and installation cost risk.

    117 Don’t get creative,stick to the OPA’s. The biggest delays to OSHPD projects are due to Post Approval issues!!! OPA – OSHPD Pre-approved system: ISAT OPA-0485 (Current expiration dates are not being enforced ). SEOR & MEOR approve seismic layouts and IOR’s inspect. OSHPD DSE reviews to determine accuracy of TDLF (g-force calculation) only . 30 Day Review Period for Post Approvals Post Approval – Non-OPA supports: Deferred Approval – Permit drawings defer items to later date Change Orders – Changes to permit drawings Information Bulletin (IB) & Addendum Custom engineering and detailing with PE stamp submitted and approved by AOR,SEOR,MEOR then AOR fills out PAD form AOR engages OSHPD field crew. DSE either signs PAD and stamps OSHPD approval on detail, or defers to Office Review. Office 30 day turnaround each round of submittal/resubmittal. OPA vs Post Approval
  • 118.
    118 OSHPD LESSONS LEARNED Lackof consistency from project to project and different opinions from each field official. Submit RFI’s early to clarify requirements. Examples of currently impacting issues that are inconsistently enforced: Set screw couplings – Non-ductile reduce seismic spacing by ½ Flexible connection from overhead utilities to wall mounted or to floor mounted equipment Detailing and engineering of vertical hangers (non-seismic) “Grey-area” code bracing requirements – pull boxes & VAV’s? No-hub riser joint stabilizers & riser clamp anchorage at each floor Make sure GC and AOR are engaging OSHPD to approve all Post- approval designs upfront OSHPD regional crews move slowly and are easily overwhelmed. Design seismic bracing and all supports early, preferably as part of 100% DD plan set.
