Morning Schedule and Program
8:00AM- 8:30AM Registration

8:30AM- 9:30AM Ann Coleman – Wiss, Janney, Elstner Associates, Inc.
Small Design Error Causes Big Disaster
Wood-framed medical office building case study of six-year old building with chronic water infiltration since construction. The roofing was identified as the original source and replaced. Six years of investigations and remedial repairs for additional leakage missed the small, but easily overlooked, design error that led to widespread wood deterioration. With the involvement of a proactive and highly motivated owner, the building was repaired and involved parties settled their differences within a year.

9:30AM- 10:30AM Paul Goetz – Aquatech Consultancy, Inc.
Moisture Management: It Should Be So Simple, So Why Is It So Hard?
Some construction mistakes take years to manifest, while others become apparent in a very short time. Water intrusion, in the form of liquid or vapor, is responsible for close to 70% of construction defect litigation. Why is it so hard to do it right the first time? Is there a common thread to the leak issue? Are the errors committed by the usual suspects? Who are the usual suspects? Paul will discuss three projects that soon after completion exhibited moisture problems. Two of the projects, a multi-unit vacation resort and a single family residence, ended up in litigation. The moisture problems in the third example, an apartment building, was addressed by the builder.

10:30AM- 10:55AM Morning Break

10:55AM- 11:55AM Gerson Bers – ABBAE
Public Enemy #1: Pre-formed Metal Form Edges For Elevated Wood Framed Pedestrian
Decks
For nearly 30 years, ABBAE’s forensic and design teams have identified and corrected damage to wood framed pedestrian deck structures caused by the use of the prefabricated concrete edge form generically known as “Con-Form”. “Con-Form” edges are a convenience for placing concrete at the edge of an elevated deck, but create havoc with waterproofing assemblies. This presentation describes what a “Con-Form” edge is, how it is typically used, damages resulting from improper waterproofing conditions created by “Con-Form” edges, and several approaches to correctly detailing exposed wood frame pedestrian deck edges.

Afternoon Schedule and Program
11:55AM- 12:35PM Lunch Break

12:35PM- 1:35PM Annie K. Lo, AIA, LEED AP – Walker Restoration Consultants
Plaza Appearance and Membrane Adherence
Annie Lo will provide an overview of a plaza project for a major housing complex in San Francisco, which is going through a second waterproofing remediation. Design concepts related to the landscaping layout, waterproofing system, expansion joints, and overall phasing from the original construction and first remediation will be evaluated and discussed with the audience. Walker’s repair concept and details will be shared for the current remediation, as well as approximations of construction costs that could have been avoided had the original design and previous remediation been approached differently. Challenges presented by the existing plaza deck configuration and unforeseen conditions during the construction will also be assessed as factors that impacted the design details and the remediation budget.

1:35PM- 2:35PM Joe Pinon – RDH Building Science, Inc.
Designing for Rain Exposure: Example Lab “Tested” Systems and Details that Failed
A structural engineer would never design a column or beam without first understanding the actual loads that the member will experience in-service. Unfortunately, building enclosures (e.g., facades, roofs, below-grade waterproofing, and windows) are too often selected from a catalog, website, or based on an ASTM test, without first understanding the actual loads the system or detail will experience in-service, or the differences between its in-service exposure and how it was tested. In this presentation, Joe Piñon will show examples of lab “tested” systems and details that failed in-service due to not accounting for the actual rain exposure and load in the design. Example failures include a rainscreen façade installed on an inclined wall, Code approved low-slope vented roofs and cement plaster exterior walls, custom window systems, and flashing details that create weak links in what might otherwise be a design that works.

2:35PM- 3:00PM Afternoon Break
3:00PM- 4:00PM Jeff Chen, AIA, LEED AP, Phillip Kelleher, AIA, Erica Reynolds –
McGinnis/Chen
Avoiding Weak Design: The Architect’s Responsibility
In 1987, Rosenberg McGinnis was retained by Milton Meyer & Co. to investigate on-going leaks at Five Fremont Center. The leaks had been investigated and repaired a number of times since 1983, less than a year after construction began. The report prepared by Rosenberg McGinnis documents their independent observations and recommendations. What started out as a simple observation of water leakage turned into a litigation case spanning a length of ten years. This presentation will uncover the architect’s responsibility to avoid weak points in the original design in order to elude unneeded headache after the project is over.

Presentations:

Water Proofing Problems- Causes & Remedies

James Strong & James Chiropolos, WJE Associates, Inc. will present two case studies examining how water proofing problems were caused and how necessary repairs were implemented.  A new hospital is about to open up; however, every time it rains, water pours into the building. Elsewhere, another building has been subjected to long-term water leakage—can the water leakage be damaging the interior structural wall framing?

Below Grade Water Intrusion on a Large New Construction Project

Jeff Chen & Phillip Kelleher, McGinnis Chen Associates, will focus on a real life example where the Below-Grade waterproofing system failed even though all industry standard precautions were taken.   The Architect’s drawings were peer reviewed by a waterproofing consultant, a high end waterproofing membrane was used, an approved applicator installed the waterproofing, and the owner hired a third party waterproofing inspector. We will discuss the project, accepted solution, and lessons to be learned by the industry.

Properly Installed Roofs That Sometimes Aren’t

Phil Dregger & Chris Nelson’s, Technical Roof Services, will focus on understanding of ounce-of-prevention tips gleaned from roof covering “disasters”. Reflective Roofs and Moisture Gain – Code-compliant re-roof project where highly reflective membrane caused wood decks to decay. Polyisocyanurate Insulation – Multi-store project where apparently ASTM 1289 compliant polyisocyanurate boards developed large gaps at joints. Built Up Roofs over OSB – Large warehouse where “common” base sheet attachment pattern failed to provide adequate wind uplift resistance.

Balcony Failure Case Studies and Best Practices

Colin Shane & Joseph Piñon, RDH Building Sciences, will explore common problems related to balcony and deck construction in wood-frame and non-combustible construction including issues related to bulk water intrusion, air leakage condensation, and building energy efficiency. Present best practices for designing durable balcony assemblies, from the basic first step of selecting durable materials; to incorporating deflection, drainage, drying as key elements of moisture control design; and finally how to integrate balconies with the adjacent building enclosure assemblies.

Learning Objectives:

By the end of this presentation, attendees will understand:

Water Proofing Problems- Causes & Remedies

  1. Identify the factors that influence the conditions for mold and mildew growth.
  2. Define ASTM D3273, ASTM D5590, SCAQMD Rule 1113 and other criteria and features of a high performance mold and mildew-proof coating.
  3. Specify the components of a complete wallcovering system and describe the utility of its parts where moisture infiltration from the wall cavity is a concern.
  4. Compile and analyze product manufacturers information that supports claims of high performance mold and mildew-proof coatings.

By the end of this presentation, attendees will understand:

Properly Installed Roofs That Sometimes Aren’t

  1. Will understand why reroofing with a highly reflective roof can cause more water to accumulate in a roof system then it did before.
  2. Will understand why ASTM 1289 compliant polyisocyanurate boards can develop large gaps at joints after installation.
  3. Will understand why attaching built up roof membranes to wood decks using “commonly accepted methods” often ends up not provide code required levels of wind uplift resistance.

By the end of this presentation, attendees will understand:

Balcony Failure Case Studies and Best Practices

  1. Will be able to state at least three common problems related to balcony and deck construction.
  2. Will be able to offer ways to mitigate said problems.
  3. Will be able to identify at least three types of waterproofing materials.
  4. Will be able to discuss a current concern regarding venting and fire-rated assembly.
