Online Task 1

Task #1 – Chapter One


While reading chapter one I had a self-realization: I should give myself more credit for listening to my husband when he talks about his day at work. My husband works in architecture and has held positions in both design and construction administration; including work at a design-build firm. The sections about the contract system, competitive bidding, construction management, etc. all ring a very familiar bell. The topic that I found most thought-provoking was bonds.
Intrigued by bonds? Yes, that’s me. I acknowledge it’s not the most exciting aspect of construction management, however, you might consider actuaries boring too. But, I beg to differ - I know some crazy party-animals that are actuaries by day. Why am I thinking about parties and actuaries? Well, the similarities between the construction contract surety bond and another kind of surety bond struck me.  I decided to do a breakdown of the construction surety bond and, for fun, do a little comparison with the surety bond, aka bail, my friend the actuary had to pay to get out of jail after his last party adventure - see, I brought it back around :)
I started my research with the very book that sparked this concept.  Lucky me! I found chapter 7 – Contract Surety Bonds. According to our textbook, Construction Contracting, A Practical Guide to Company Management, “it is usual practice for construction contracts to require two separate contract bonds, one bond covering performance of the contract and the other guaranteeing payment for labor and materials.” The reason for this is simple enough; the dual bond practice provides a more evenhanded distribution of protection by separating the interest of the owners and contractor’s payees. Under a single bond the owner has priority for payment over workers, subcontractors, material suppliers, etc. and therefore has the potential of exhausting the face value of the bond through its claims before the others even get a crack at recovery. This practice affords little, if any, protection to injured parties subordinate to the owner for payment.
The performance bond and the payment bond are the two bond instruments.
The performance bond protects the owner and, as the name implies, guarantees performance in substantial accordance with the terms of the contract. If the contractor defaults, the surety is responsible for the burden of contract performance – customarily covering any warranty period required by the contract.
The payment bond protects the third parties to the contract that are used in whole or in part of the performance; i.e. it guarantees payment for labor and materials used in construction. Potential claimants include those who have direct contact with the general contractor or one of the subcontractors.  A byproduct of the payment bond is protection for the owner and financiers from liens that can be filed against the project by unpaid parties to the work.

A Frivolous Comparison


Task #2 – Project Delivery Methods


As one can tell from Task #1 – Chapter One, I like comparisons and I found this detailed one from CSW Contractors.

The Design-build method is of most interest to me and apparently many others as well. According to the Design Build Institute of American, design-build has been rapidly gaining market share in the United States. The design-build method combines the design (Architect-Engineer) with the builder (general contractor) in a single entity.  The article cited in our assignment mentions two main advantages to using a design-build contract.

1.   the construction team is motivated to work with the design team to develop a design with constructability in mind. In that way it is possible for the team to creatively find ways to reduce construction costs without reducing the function of the final product. The owner can expect a reduced price due to the increased constructability of the design.”
                                                                          
2.   early mobilization and construction activities are able to proceed concurrently with the design.”

In my opinion there is another significant advantage to the design-build contract and that is:

 3.  Communication and respect. In my experience the relationship between the architect-engineer and the general contractor is often full in disharmony. This stems from lack of communication and respect for each other’s areas of expertise – each thinking the other “just doesn't get it” or the label “dumb-ass” comes to mind. The construction business host some pretty big egos. Combining these two parties in the beginning can solve both issues. The general contractor has the opportunity to have input in the design at its earliest stages  and can also gain an understanding of architectural and engineering decisions. Additionally, functioning as coworkers brings the prospect of earning respect.

There is an inherent conflict of interest in that by acting as a single entity one function can take actions that affect how the other function contributes to the bottom-line.  For example, a building could be designed in order to increase profits during construction.

The most common design-build contracts involve a general contractor hiring an architect for design services of a structure the contractor is building for the owner, its client. However, recently making a comeback is the Architect-led design-build method.  I wonder why the set-up went away, honestly. This wiki article about architect-led design build says “historically, most construction from the ancient pyramids to the Eiffel Tower was run by the same person who designed the structure. It was not until the twentieth century, primarily in America, that design professionals (architects and engineers) separated themselves from construction contractors and materials vendors, forming separate professional trade organizations, and popularizing methods of construction that promoted separating design from construction.” This concept of the architect as the Masterbuilder was employed in construction for the millennia prior to the twentieth century.
The workflow in the architect-led design-build is described as “the dynamic architect-led design–build workflow reintroduces discursive coordination, collaboration and consistent, reflexive managerial oversight over the arc of a project schedule, maximizing project efficiency (time, cost, functionality) without compromising design performance or the quality of project outcomes. Design–build can be an iterative and dynamic method, reflecting an emergent design process in which decisions are made holistically and progressively refined as interdependencies are prioritized, identified and coordinated.” The graphic below three models of architect-led design-build contracts. 




Task #2 – Construction Bidding

I found the following graphic on the website for PlanSource: OnDemand Construction Software. It is a great depiction of the elements of construction bidding.







Task #2 – Building Codes

There is a very cool interactive map on the website for the International Code Council, "people helping people build a safer world" - a noble cause, I might add.

The map lets you select and view states that have adopted the following building codes:


  • The International Building Code (IBC) is in use or adopted in 50 states, the District of Columbia, the U.S. Virgin Islands, NYC, Guam, and the Northern Marianas Islands.
  • The International Residential Code (IRC) is in use or adopted in 49 states, the District of Columbia, and the U.S. Virgin Islands.
  • The International Fire Code (IFC) is in use or adopted in 43 states, the District of Columbia, NYC, Guam and Puerto Rico.
  • The International Energy Conservation Code (IECC) is in use or adopted in 45 states, the District of Columbia, NYC, Puerto Rico and the U.S. Virgin Islands.
  • The International Plumbing Code (IPC) is in use or adopted in 34 states, the District of Columbia, NYC, Guam, and Puerto Rico.
  • The International Mechanical Code (IMC) is in use or adopted in 43 states, the District of Columbia, NYC, Guam, Puerto Rico and the U.S. Virgin Islands.
  • The International Fuel Gas Code (IFGC) is in use or adopted in 44 states, the District of Columbia, NYC, Guam, and Puerto Rico

Online Task 2

Task #1 - Chapter Four




The Brooks Act is a significant piece of legislation for those in the architecture and engineering industries (read the full text of the law). The definition on Wikipedia is "the Brooks Act is a United States federal law passed in 1972 that requires that the U.S. Federal Government select engineering and architecture firms based upon their competency, qualifications and experience rather than by price." 

Two Reasons this legislation makes sense to me:

First, it gives preference to quality over cost - and explicitly so. Simply, you get what you pay for. A lower fee firm will likely have less quality control during the design and engineering process. As stewards of the taxpayers' money, the government attempts to secure the greatest value in procurement (something that, despite the negative press, is presented to me daily at my job in the Leasing Division at the General Services Administration). Professional experience can pay off in long-run by avoiding costly rookie mistakes.

Second, it gives small businesses an equal opportunity of being awarded the contract. The principal of economies of scale gives advantage to large firms when basing the selection on price alone. The government prefers to invest in areas that can spur needed growth as demonstrated by side-asides for small businesses. According to our textbook, Construction Contracting, A Practical Guide to Company Management, "Small design businesses are identified by the U.S. Small Business Administration as those with annual gross billings of less than a specified maximum average value."

The American Council of Engineering Companies (ACEC), provides a description of how to use Qualifications Based Selection as set in the the Brooks Act. Basically, it breaks the process down into "seven basic steps involved in pursuing federal design work under QBS: 


1. Public solicitation for architectural and engineering services

2. Submission of an annual statement of qualifications and supplemental statements of ability to design specific projects for which public announcements were made 

3. Evaluation of both the annual and project-specific statements 

4. Development of a short-list of at least three submitting firms in order to conduct interview with them 

5. Interviews with the firms 

6. Ranking of at least three of the most qualified firms 

7. Negotiation with the top ranked firm." 



Task #1 - Architect Profession

We had been married less than a year when my husband told me he wanted to change his educational pursuits from Business Administration to Architecture.....my first thoughts went something like this clip from YouTube. We also looked up the profession Occupational Outlook Handbook and asked, "are you really, really, really sure?" 



Yes, he was really sure and in spite of struggling through the long hours and grumpy moods that came along with earning his Bachelors and then Masters degrees in Architecture my opinions have changed. Fittingly, I found this video on YouTube while looking for the previous one - it describes my current feelings pretty succinctly.



Aside from my own feelings, I've noticed the feelings of others as well and it surprises me how strong the opinions are about architects. It seems its a love'em-or-hate'em situation trapped in a can't live with'em, can't live without'em paradox. I for one, love'em ;) 

Task #1 - Architectural Software

After reading the assigned ehow article I asked my husband, "what do you know about architectural software?" The answer was longer than I expected. Actually, his first words were "geeze lady, I could talk about this for hours." Luckily, for me he didn't. I think I got his basic opinions and I've listed them below (I probably lost some of that listening credit I mentioned earning in Online Task 1).

AutoCAD: a digital drafting table. Which is a nice way to sketch rapidly - a virtual pen to paper. Advantages to AutoCAD are speed and shallow learning curve.

Building Information Modeling (BIM): has a much steeper learning curve. Overall it improves efficiency in the long-run but it can't be used without AutoCAD. One system he has experience is Revit, "a Building Information Modeling software developed by Autodesk. It allows the user to design with both parametric 3D modeling and 2D drafting elements."

Online Task 3

Task #1 - Chapters ten, eleven and twelve

Reading about the topics Project Management and Administration, Project Time Management and Project Cost Management, the concept of Value Engineering kept entering my mind. Value Engineering is described in our textbook as "finding a better way to accomplish a construction project at less cost." I have also read that "Value Engineering (VE) is an effective technique for reducing costs, increasing productivity, and improving quality." The point is, this is some important stuff. Especially in delivering a project in the most efficient manner with the ultimate goal of satisfying the client.

 The Society of American Value Engineers (SAVE) says that the maximum value for the project can be derived as Value = Function/Cost where

"Value is the reliable performance of functions to meet customer needs at the lowest overall cost.

Function is the natural or characteristic action performed by a product or service.


Cost is the expenditure necessary to produce a proejct, service, process, or structure.

The systematic and structural approach comes from the VM job plan. SAVE International®’s standard job plan consists of six phases:

1. Information Phase: Gather information to better understand the project.

2. Function Analysis Phase: Analyze the project to understand and clarify the required functions.

3. Creative Phase: Generate ideas on all the possible ways to accomplish the required functions.

4 .Evaluation Phase: Synethesize ideas and concepts to select feasible ideas for development into specific value improvement.

5. Development Phase: Select and prepare the “best” alternative(s) for improving value.

6. Presentation Phase: Present the value recommendation to the project stakeholders."


It is hard not to recognize the importance of Value Engineering. I have linked to this excerpt from the Architect's Handbook of Professional Practice on Value Analysis. It has some really great graphics depicting the concept.

I know I jumped back a few chapters there, but sometimes the thoughts just flow. So moving on....

Doing the additional research on the topics Project Management and Administration, Project Time Management and Project Cost Management I found a website for an European firm with offices in Ireland and in the United Kingdom called Penlon Projects. The site has two list that nicely breakdown the elements important to Project Management - I've included them below:

"Our construction Project Managers have experience in:
  • Operational, financial and management accountabilty
  • Management of projects, including feasibility studies, programmes, drawings, tendering and appointment.
  • Technical advice and support
  • Space planning
  • Claims Managment & costings
  • Detailed construction & conception designs
  • Engineering calculations
  • Design evaluations
  • Electrical site management
  • Procurement & logistics managment
  • Quality Managment
  • Programming" 

"Our specialists have backgrounds in:
Penlon Projects
  • Project Management
  • Construction Managment
  • Environmental, Health & Safety Management
  • Chemical Engineering
  • Logistical Management
  • Facilities Management
  • Training
  • Electrical Deisgn
  • Mechanical Design
  • Building Services
  • Quality Management
  • Technical Support
  • Procurement
  • Business Development
  • Instrumentation"
Plus look; I really like that space they're in too (just sayin'). 



Task #2 - Modular Residential Construction

I have always liked the idea of modular construction - it just makes sense. I like the quality control that goes along with the factory components. The same crew does the same tasks everyday. I imagine they get very good at what they're doing. Whereas, out in the field the worker that is available gets the job in many cases. I also appreciate that materials are better protected from the elements during construction with the modular method. With much of the work done indoors, rain, insects, etc. are not a factor.  

There are deep preconceptions that come with the word "prefabrication." I find myself having to convince people that prefab isn't all bad. Often I think the first image that pops into some peoples' minds is a trailer park. The next image is of a tornado whipping through picking up the homes and sprinkling people out like salt and pepper shakers. Here are some images of what pops into my mind when I think of modular homes.








Another plus to modular construction - it can often be done in sustainable ways, promoting green living. This article in from My San Antonio is about the project pictured above by Lake, Flato Architects. 

I found out more about the green qualities of modular housing when I read Green, a Blog About Energy and the Environment on The New York Times website. It points out the following ways modular construction is considered "eco-friendly - from reduced waste to a smaller construction footprint."


  • recycling is huge in a modular plant
  • "To withstand the stresses of long-distance shipping, for example, modular homes are typically built with thicker walls and floors and are held together tightly with screws and glue — instead of just nails. A side effect of this, industry representatives note: Higher energy efficiency due to the extra insulation and tighter, less draft-prone seams"
  • The industry is experiencing shifts towards providing more sustainable living. For example, 
    • luxury market amenities like built-in rainwater harvesting, grey water reuse, tankless water heaters and bamboo flooring all cater to the environmentally minded consumer and help reduce their carbon footprint.
    • "moving away from the not-so-eco-friendly materials — toxic paints, PVCs and so forth — that have been used in the past"
    • "using lumber certified by the Forest Stewardship Council, a sustainable forestry watchdog group."

Unfortunately, green living is expensive! The good news is that modular construction compliments green living practices not only through sustainable construction practices but also by allowing prices to be kept at a minimum through bulk purchasing - ironically, that big-box thinking those with a green lifestyle avoid, but I digress.

Final thoughts: Modular house? Let's do this!

Online Task 4

Task #1 -  Chapters thirteen, fourteen and fithteen

Topics: Lab Law, Labor Relations, Project Safety and.......OSHA.


OSHA stands for the Occupational Safety and Health Adminsitration, an agency of the United States Department of Labor. OSHA's mission is stated on their website as "with the Occupational Safety and Health Act of 1970, Congress created the Occupational Safety and Health Administration (OSHA) to assure safe and healthful working conditions for working men and women by setting and enforcing standards and by providing training, outreach, education and assistance." In my short time working for the federal govenment I've learned that organizational hierarchy is a big deal, so it's only appropriate that I include the link for OSHA's organizational chart while we're on the subject.

I found this website for Safety Trainers, a training and consulting firm based in Massachusetts, insightful as to the nitty-gritty of OSHA - ask those who teach, right? Simply viewing the course listings and offered services (listed below) demonstrates the complexity of OSHA and its mission.  

  • Health and Safety Consultant
  • Onsite Safety Inspections
  • Forklift Driver Certification
  • Respiratory Fit Testing Program
  • Fall Protection Training
  • Customized Documentation

An aside: I appreciate the coincidence that this company is based in Massachusetts, the place of "nation’s first safety and health legislation in 1877, requiring the guarding of belts, shafts, and gears, protection on elevators, and adequate fire exits in factories." Quoted from this (72 page!) article titled Reflections on OSHA's History. 

I think to appreciate OSHA one must understand its history.This article, The Job Safety Law of 1970: Its Passage Was Perilous, from the Department of Labor says it nicely. The important take-away is that while the regulations may seem tedious and overly intrusive, they are rooted in a very real need to protect people. The article sites "the reports of State labor bureaus in the 1870's and 1880's were full of tragedies that too often struck the unwary or the unlucky" as catalyst for the outcry for reform.

The proof is in the pudding - view OSHA's statistics and data page.

Task #2 - Building in the South Pole

The video of building in the South Pole is really about building in extreme conditions. Considering the opposite conditions and me, always dreaming of a beach-house, I looked into building in extreme heat and other extreme conditions. This article, Building to Last: Designing Under Extreme Conditions (building and remodeling on the shore requires storm-savvy design and time-tested techniques) dives into the subject of designing to withstand earthquakes, erosion and howling winds. 

Task #2 - Concrete Printing and prefabrication




Watching the videos about concrete printing and prefabricated concrete reminded me of a story about a famous inventor that advocated for concrete homes but didn't succeed. A quick Google search turned up the answer to the first question, "who was the inventor?" Thomas Edison, one of American's most famous inventors. The answer to the second question, "what was his deal with concrete houses?" was found in this article, Why Dolores Chumsky Hates Thomas Edison. I think Edison would be thrilled about the work going on with concrete printing and prefabrication. Edison, as most inventors, was way ahead of his time; and this time it shows in his notions about living with concrete. Thomas Edison was into concrete - who knew?!
