​It Is All About Money

One of the ways in which we attempted to distinguish ourselves from other firms was by taking care of our client’s money questions. In my opinion, and in my experience, too, money is usually the main thing that will undermine a project. 
​
I don’t want to have the money conversations after it has become an explosive topic. So right from the beginning we attempted to help our clients set up a sound budget.

One Good Way To Save A Project

5/18/2014

About the time I was getting out of college, John Portman, an Atlanta architect, was designing the first Hyatt Hotel with an atrium lobby, pictured above. Unlike most architects, Portman was deeply involved in the development of his projects, not just the design. I was fascinated. And when I came across an article describing all the costs that went into one of his projects, I typed it up. Yep, this was the pre-electronic (caveman) era and electric typewriters were all the rage. Photocopiers were the size of a VW bus and the entire country shared three of them, one per time zone. 

The list was really an eye-opener. I had never imagined there were so many things outside of design and construction that went into a project. The construction cost was just one simple line item, and the article explained that construction cost rarely exceeded 2/3 of the total cost. Even though these projects were major commercial undertakings - hotels, merchandise mart, office high-rises - there were many similarities to the schools that I was working on. We didn't consider hardly any of the items in the list, but the Owner had to. Here is the list I typed up.

I Found A New (To Me) Cost Estimating Tool

1/15/2014

 
Website
Click Image for Construction WorkZone
Here’s how I used it on a recent remodeling estimate.

First, I assembled a list of line items that will be needed by editing a specifications Master Table Of Contents.

Second, I used Construction WorkZone to look up the unit costs on the line items. I found 54 of the 66 line items in Construction WorkZone. This is just a few less than I might have wanted. I used allowances for several line items because the effort of putting together a quantity did not seem worthwhile. So I basically guessed at about six line items out of 66. 

Third, I added a ten percent contingency as a judgement call. The project is in CDs; it is a remodeling; it isn’t very large. 

The last step is to add the quantities and do a gut check. Here’s what it looks like so far.
For years my firm bought ’Construction Cost Data’ to assist with unit costs in our estimates. More recently CostWorks provided an electronic version that saved your research for you. Now that I’m retired the $200 per year for either seems like overkill for what estimating I am likely to do. 

Fortunately, I stumbled upon Construction WorkZone about a year ago. On an annual basis, Construction WorkZone is one quarter of the cost with about 80-90% of the usefulness. (Even cheaper if you subscribe just when you need it.)
Estimate
Estimate in Process
So here is how Construction WorkZone works. 
Register for free to look up 10 items; or sign up for monthly use - $.99/first month, then $3.95/mo., cancel anytime. 
The data search looks like the screenshots below.
The localized cost modifier seems to be a constant percent when I spot checked it. So you could do that just once on your subtotal.
The key features of cost estimating don’t require exact unit costs, which don’t exist anyway. Just look at the bids you receive for proof. 

SUMMARY - PROs
Low Cost
Reasonably comprehensive
Lots better than guessing
Low learning curve

SUMMARY - CONs
A little more time-consuming than I would like
Must transcribe costs, which is error-prone
Results not saved for you (so take screenshots??)

Budgets And Planning - It's All About Money

7/1/2013

 
Money
When you are embarking on a new project, it is crucial to have a plan for the project. You need to know the goals you need to achieve for success. This building planning process has six parts that build upon each other:
  • Space needs
  • Building characteristics
  • Project constraints
  • Land use
  • Scheduling and implementation issues
  • Cost and budget
All of this information is designed to answer just one question (although there are many ways to state it) -  "How much will the building cost?

From that point of view the whole planning process is about money. Each of the six areas of the planning process, while necessary in its own right, are also needed to answer that bottom-line question about cost. Space needs translate directly into construction costs; and so do the building characteristics and land use. These might also affect design costs. Project constraints and implementation issues can affect design costs as well as other "soft" (non-construction) costs. Finally, budgeting is about bringing all this cost information into alignment with the money that is available to fund the project.  

It really is all about money. 

To keep nasty surprises at bay, we've found that, if your budget is comprehensive, then surprises are much less likely to occur. "Comprehensive" means lots of detail; and lots of detail also makes your budget more accurate. Besides the main costs of construction there are many issues that are easy to underestimate or overlook altogether. Construction costs are the "hard" costs. The "soft" costs fall into two categories: Design, Development. All these costs are listed in our template for a comprehensive Project Budget. Strive to incorporate all of these budget concepts into an integrated process for answering "How much will the building cost?"

How To Be A Genius At Estimating Costs

2/22/2013

It's easy. For the past fifteen years we have used an all-inclusive template for documenting our estimates of project costs. The first embedded template shows our format. This part summarizes every cost that we think the client will face. The construction costs are pretty obvious, and even the breakdown isn't very unusual. 

However even during Pre-Design we are able to create this level of detail. The reason we can do that is the second embedded document - the assumptions and the quantities we derive from those assumptions. From there we feed the quantities into an RS Means CostWorks model for the construction type that we anticipate. The result is surprisingly accurate. 

Having created a project cost projection, it is important to live within the assumptions that you have made. Very few architects do this and our reputation regarding cost control is a result. There are all kinds of weasel words to hide behind, but you don't see contractors shying away. It's not FM. It takes a little time, but you recoup it on every estimate you do thereafter. 

The secret sauce is the quantity takeoff without drawings. This is done once and rarely needs to change. Special features just become new line items. You set up formulas in your spreadsheet to calculate every element of construction that you have. Many of these are very simple. For instance, the quantity of flooring usually equals the net area of the building. The amount of carpet flooring is simply the net area times the percent of the floors you think will be carpet. The quantity takeoff spreadsheet refers to the assumptions that you have documented on the assumption sheet of the workbook. 

Another example is windows. This is more complicated because it works with assumptions about gross area, building proportions, number of stories, story height, and percent of exterior wall that is glass. The trickiest calculations are square feet of interior partitions and number of doors. These require factors pulled from a table. The factors can be found with some digging. If you work with just a few building types, you can develop your own from past projects. 

Once the data is entered, we have all the quantities. The last step is to transfer the quantities to the model you built in Means CostWorks. With a little forethought this is a simple transcribing exercise that takes twenty minutes. When you have your system set up, which will take about three man-days, an estimate can be pulled together in an hour, including the twenty minutes of transcription. You are probably spending more time than that and getting poorer results.

Finding information on Architekwiki can be done in two ways.

The first way is by using the Google site search widget to filter the articles based on your key word(s).

The second way is by using the categories of the blog in question to filter the articles. We will address them one at a time. [Footnote: from time to time duplicates show up in the lists of categories for unknown reasons. I attempt to eliminate them.]

For the WIKI page there are 20 categories, listed below. Every article is tagged with one of the first four categories and also with one or more of the other 16 categories. (You will note the actual category list are in alphabetical order.)

WIKI categories and a brief description of their intended content.
  1. Business Development - sales, marketing, promotion, PR, etc
  2. Management - steering the various aspects of the practice of architecture
  3. Services - the architectural services provided to clients

  6. People - staff, clients, consultants, vendors
  7. Process - a standardized multi-step task 
  8. Projects - a unique and complex undertaking for clients or for the practice
  9. Records - saved communications and work products
  10. Tools - physical, digital or conceptual ways to do work
  11. Miscellaneous - catch all 
  12. Legal Issues - contracts, laws, codes
  13. Money - fees, value, compensation, etc
  14. Estimating - projecting or predicting costs, quantities, and time
  15. Planning - determining the steps required to achieve a result
  16. Standards - adopted templates or methods 
  17. Design - creatively determining the possibilities and deciding among them
  18. Specifications - written guidelines, requirements or instructions
  19. Time - using and measuring it
  20. Concepts - ideas and ways of looking at an issue
 
For the DETAILS page there are 14 categories, each represents a category in the UNIFORMAT II system. This article will give you more information about UNIFORMAT. The one exception is Proj Dwgs, which is used to tag articles about an entire project.

For the BLOG page there are 6 categories as follows. Others may be added from time to time.
  • Chronology - articles that document the growth of Architekwiki
  • Humor - attempts at being funny
  • Miscellaneous - not worthy of individual categories
  • Opinion - me just saying ...
  • Thoughts - me just thinking outloud on the screeen
  • Work In Progress - stuff that is being planned (maybe)
