| USPS STD-4C Compliant Mailbox Systems |
Effective October 5th, 2006, USPS STD-4C Compliant
Mailbox Systems are mandatory on all NEW CONSTRUCTION and
MAJOR RENOVATIONS.
USPS Standard-4C Wall Mounted Centralized
Mail Receptacles replaces United States Postal Service
Standard 4B Receptacles, Apartment House, Mail, which
governs the design of wall-mounted centralized mail
receptacles whether utilized in commercial, residential, mixed
residential or other types of structures. Buildings with
permits dated on or after October 5th, 2006 must
have USPS STD-4C receptacles to receive Postal deliveries.
Existing buildings are exempt from the new standard.
Security and efficiency are the primary
reasons for the first revisions to mailbox regulations since
1975. The standard creates a new form factor and increases the
minimum size requirement to 12" wide by 15" deep by 3" high
and completely eliminates the vertical form factor (5"W x 6"D
x 15"H). Standard 4C also requires one parcel locker per ten
tenant compartments. Security features and lock design
requirements are more stringent with new STD-4C, which also
includes mandatory security testing done by the USPS. Finally,
the new 4C Standard includes a requirement to meet the
Americans with Disabilities Act (ADA) standards.

| CAD Corner: Lighting Design Software |
AGI32 by Lighting Analysts, Inc.
Predict lighting system performance for any
application from one luminaire in a jail cell to hundreds of
luminaires in a professional sports facility. Interior or
exterior, AGI32 can build environments for most any electric
lighting or daylighting application with unlimited luminaires,
calculation points, and reflective or transmissive
surfaces.
AGI32 is not only a comprehensive point by point
program, but a lightning fast, photometrically correct, color
rendering tool as well. Imagine computing all of your point by
point values simultaneously with a full color image. Now, not
only can you review the "numbers", you can also incorporate
accurate visualization into your everyday lighting design.
This is enormously powerful for both conceptualization and
presentation.
A completely new CAD import engine
offers compatibility through ACAD 2006.

| Spotlight On: Tension Structures |
Art & Engineering
Few methods of
building match the drama and delight of lightweight tensile
structures. Tensile structures consist of cables and fabric in
tension. Uniquely, the architectural membrane forms both the
structure and skin of the building envelope. The cables carry
the gravity loads while stability and resistance to wind
uplift is provided by the weight of the roof deck system.
Conceived by renowned architect Helmut Jahn, the
Sony Center on Pots-damer Platz in Berlin is a
spectacular tension engineering feat consisting of ten stories
of glass covered with an outstretched fabric tent roof
connected via steel cables to a circular girder that supports
the whole on bearings attached to the surrounding buildings...

| Do You Do BIM? Part 2 |
New software is but one aspect of building
information modeling — be sure you understand all the
challenges of this new approach to the building cycle.
Brandt
R. Karstens, Cadalyst, June 6, 2006.
Understanding BIM (building information
modeling) and its benefits is the first step toward making the
BIM transition. A relatively new approach to building, BIM
brings together the major stakeholder groups early in the
building process — architects,
mechanical-electrical-plumbing-structural engineers, building
contractors and owners — and offers benefits for all. BIM
facilitates information sharing, breaks down traditional
barriers — and cuts costs.
But to tap the full
potential of BIM, you must understand it is not simply a
technology implementation. In this article, Brant R. Karstens
examines software as an enabling technology for BIM and the
challenges of BIM implementation. View Article
