| Repointing: Less is not always more |
| Failures |
| |
|
When repointing mortar joints in an existing structure, successful long-term performance depends on a number of factors. A lack of understanding of substrate materials and conditions, insufficient joint preparation, less than adequate skill or care during mortar installation and curing, and an overly limited repointing scope can lead to premature failure of a masonry joint repointing program.

The ornate façades, designed by LS3P, showcase concrete pillars and exteriors glazed with neutral-reflective, low emissivity (low-e) glass, which helped the project achieve the Leadership in Energy and Environmental Design (LEED) Gold certification. |

| AN ERROR IN CONFORMED DOCUMENTS – NOW WHAT? |
| Conformed documents are procurement documents that include addenda items and accepted alternates. The original drawings and specifications are usually updated by the A/E and can be incorporated into the Owner-Contractor Agreement by reference. What happens when the A/E accidently omits an addendum item from the conformed documents? Are those gold-plated widgets the Owner insisted on no longer in the contract? Does the A/E need to issue their first change order to include missing items? Should the Contractor just ignore conflicts like this because, after all, the Owner-Contractor agreement references the Addenda, too? Or, just to keep it clear, should the A/E issue a disclaimer of some kind to the Contractor that will resolve the issue automatically when a conflict occurs between conformed documents and the original procurement documents? If you have seen a disclaimer of this type what did it say?

| PARTISAN PROFESSIONALS: CONTRACTORS DESERVE ETHICAL TREATMENT |
| In managing their myriad priorities, architects, engineers, and geologists are obligated to behave ethically, both by their licensure and codes of conduct established by non-profit, professional organizations. However, design professionals’ eagerness to be viewed as supporting their clients’ short-term interests, while preserving their own reputation and client relationships, sometimes comes at the expense of ethics and objectivity. This is especially true when consulting engineers, architects, and geologists are too partisan against construction contractors retained by their clients.
