Legal Update: What's New and of What Do Need to be Aware

As our industry evolves, the legal relationships between it's participants change. New technologies, services, and project delivery methods have emerged in the past few years which created need for adjusting the balance of risks and rewards among the construction community's members. Additionally, judicial decisions on disputes have added nuance to those of us not involved, but who face similar circumstances.

See the Light: Lighting Concepts and Solutions

You have seen the language of lumens, footcandles, dark sky, photometrics, and Kelvin color temperature. But, do you know what they mean, and how lighting designers mix them together to create ambiance?

March 01, 2016

Fire-Rated Glazing and Framing

Once relegated to small vision panels in fire-rated doors, glass which has a fire rating can now be large expanses of interior and exterior walls. Depending upon the expanse of the glass, the fire testing protocols will change. With those changes, come terminology differences (from fire-protective glass to fireresistive glass) which can be confusing.

From Project Manager to Project Leader

This month we will take a look at the effect of project management affecting how we manage tasks and activities. With the reality that those activities must be performed by people, those people need to be led. Attendees will learn how to get the most from project team personnel by focusing on key attitude changes.

Signs and Light Emitting Diodes

As the usage of Light Emitting Diode lamps has been slowly replacing incandescent, fluorescent, and high intensity discharge lamps for conventional lighting in buildings, they are transforming the sign industry. Traditionally the domain of fluorescent or cold cathode (think neon) lamps, the need for longer lasting light sources has come to dominate the industry's needs. Most new signs are now equipped with LED lamps because of their long life and color stability.

October 01, 2015

Glass Performance and NFRC Ratings

In the realm of fenestration systems (doors, storefronts, curtain walls, windows, and skylights) glass plays a large role in their performance. During the past 12 years, the energy performance of fenestration systems have been challenged by Energy Code revisions to reduce their energy transmission.

11th Hour Simulation What is a "Hard Bid?

Many industry professionals have at least some hand in submitting or evaluating a type of proposal that is often called a "hard bid." This type of proposal typically requires that the general contractor prepare a single lump sum bid for an entire project that is then submitted to a project owner in a sealed envelope by a certain time on a certain day — known

as Bid Day.

Collaboration Part 7 - Change, Change, Change

We've had two collaboration meetings since my last blog posting on the collaboration effort I'm participating in. To recap, our firm is involved in a very large, biomedical research building project at a local public university. The delivery method is CM-at-risk with design-assist for major trades. Looking back through this blog, you can read about the entire process. It all started here. 

June 01, 1996

Revenge of the M-Word

The metrication bandwagon rolled on during the last year. In this Felt-Tip, we follow-up on some recent developments

discussed in last year's Felt-Tip on metrication. We also highlight how the steel industry is metricating.

September 01, 1995

Fire Safing Curtainwall Systems

Many types of curtainwall construction have a serious short coming—fire may go through it and around it; through the horizontal space between the edge of the floor slab and the curtain wall or around the exterior of the building through the curtain wall system.

June 01, 1995

The M-Word Strikes Back

The progress toward a metricated construction industry marches forward. The primary force behind the metrication process continues to be the Federal Government. If you are doing projects for federal agencies, you are probably preparing documents describing construction with metric units of measurements.

April 01, 1995

Expansion Joint Covers

They have to resist some tough conditions and must always work, yet be hardly noticed. They result when new buildings are constructed next to existing buildings, or when a building is very long (usually more than 100 m (300 feet)). They occur in hospitals, schools, airports, and shopping malls.

Evolving EIFS

If you remember looking at the December 1993 issue of The Construction Specifier, you were treated to a series of advertorials on Exterior Insulation and Finish Systems, commonly called EIFS [pronounced EeeeFffSss]. Disregarding the articles's contents, it was a masterpiece of slyly hidden advertising by the four major EIFS manufacturers.

March 01, 1994

What is Wrong with Brick Masonry Veneer Over Steel Studs?

In keeping with CSI's purposes and objectives we present a paper originally presented in the February 1992 edition of The Masonry Society Journal. C layford T.

Now for our second installment of chemical terminology (used in construction) that is easily misunderstood.

October 01, 1993

ASTM C90, A White Paper Type I vs. Type II Block

The decision of whether to specify Type I or Type II concrete masonry units per ASTM C90 has long been a dilemma for both the concrete masonry producer and the design professional. On the surface, it would seem that to specify a Type II unit would be to specify an inferior block.

September 01, 1993

Insulation Evolution

How does your choice of roof insulation affect the environment? Probably just thinking about the subject weren't you? Most likely not, but this Felt Tip will get you thinking [hopefully] about it.

Okayyy, so much for disclaimers! Why a disclaimer, you ask? We're going to discuss the "A-word". Yes! Asbestos. Asbestos in resilient flooring. Specifically, the removal of resilient flooring containing asbestos.

May 01, 1993

De-Bugging Your Buildings

Bugs been getting to you? No, not Bugs Bunny, Doc! Were not referring to those bugs in your computer, or those very discrete listening devices, either. Bugs — as in insects, microbes, fungi, and bacteria. Stuff that's icky and yucky. Things which can make you sick. Stuff that can make the buildings you design (and work in) sick.

April 01, 1993

Construction Chemicals -1

If you read the article "Architects, Chemistry, and Construction" on page 27 of the July 1992 Construction Specifier we hope you will appreciate the following attempt to ease those pangs of not knowing something. So, if you are confused by the multi-syllable words being used today to describe the many compounds used in today's construction chemicals [besides being difficult to pronounce], here are some of them, what they mean, what their purpose is, and where they are used.

March 01, 1993

ASTM Standards Update

Well, wouldn't you know it! Somebody suggested that since we are letting you know of the new ASTM Standards, we should let you know of ASTM standards which are being discontinued (without change, revision, re-approval, or editorial change). This does not mean they won't be of use in the future, but they won't be revised.

November 01, 1992

The Painted Glass Blues

You have probably seen it without recognizing it. It is done to hide the unoccupied spaces behind the storefronts of many buildings. In fact, it can become "art".

October 01, 1992

ASTM Standards Update

Regularly [most likely once a year, but you never know, we might change our mind] we will provide you with a list of new [not revised, re-approved, nor renamed] ASTM Standards, so that you can stay aware of the newest material and test standards from the American Society for Testing and Materials.

September 01, 1992

Wood Design Values Change
