Best Practices for Project Management, Design, and Construction of ...

Drawing Content
Equipment may include medical, mechanical, plumbing, electrical, food service, or accessory
items such as shelving and appliances. Equipment may be installed by the contractor, the owner,
or special vendors. Regardless of who performs the installation, for the purposes of construction,
all items need information on the drawings to describe their installation. Anchorage of standard
items, such as ceilings and casework, is best covered in the drawings by typical details. These
may include typical backing-plate requirements for wall framing and clip attachments to walls,
counters, and floors for miscellaneous items found throughout the project in toilets, kitchens,
treatment and exam rooms, etc. Drawings may also cover the anchorage of items exempt from
plan review (discussed in the preceding section). However, such details are subject to plan
review, and changes from the approved drawings may generate a post approval document
review.
For those pieces of equipment that exceed the criteria for exemptions, specific details designed
by the EOR or provided by the manufacturer's (California-registered) engineer are required on the
drawings. Some manufacturers have engineered anchorage systems that have been submitted to
OSHPD under its Anchorage Pre-Approval Program. Pre-approval is for anchorage only and
does not include product approval. This program allows the use of drawings for equipment
anchorage, in most cases, to show just the pre-approval number. However, in some cases, the
actual details submitted by the manufacturer should be reproduced on the drawings for the
reviewer to verify that the anchorage design is correctly applied to the project. If this is required, it
will be stated in the pre-approval documents. The list of pre-approved anchorage for equipment is
maintained by OSHPD and provided on its Website for use by design professionals. If a
pre-approved product or system is specified, it is vital that the design team review the actual
pro-approval documents to confirm that they conform to the project requirements.
The acceptability of proprietary fastening systems should be confirmed with OSHPD. For
attachment to concrete, Title 24 covers expansion-type and adhesive-type anchor systems. Other
types of fasteners are subject to OSHPD approval. The use of some fasteners, such as shot pins
and screw-type anchors, is limited by OSHPD FDD. Additional information in the form of CANs is
available on the OSHPD Website.
When equipment cannot be specified at the time of submittal, the design team may request that
the item be deferred. Deferred items are to be listed in a schedule on the cover sheet of the
drawings. However, assumptions should be made for equipment weights, location, and utility
connections to allow the reviewers to check related items (such as the supporting structural
framing) and to permit tracking of follow-up Amended Construction Documents for anchorage
details.
The drawings and specifications must fully describe the performance and loading criteria for the
deferred item.
