What are the GCA Design Patterns
« on: April 17, 2006, 03:21:34 PM »
Architect Christopher Alexander is credited with bringing forth the concept of "design patterns" in architecture. E.g. Christopher Alexander, Sara Ishikawa, Murray Silverstein, Max Jacobson, Ingrid Fiksdahl-King, and Shlomo Angel, A Pattern Language. Oxford University Press, New York, 1977.

According to Alexander, "Each pattern describes a problem which occurs over and over again in our environment, and then describes the core of the solution to that problem, in such a way that you can use this solution a million times over, without ever doing it the same way twice."

Alexander was writing about patterns in the construction of buildings and metropolitan areas. But, can't the same idea be applied to GCA? It has been applied to software design.

Wouldn't a primary design pattern in GCA be "Redan". How about "Cape"? Another recurring pattern is the long hole bending left around a hazard, perhaps called "Pebble18".  It should also be noted that patterns can be composed. For example, within the Pebble18 pattern could be composed a second shot landing area Cape, and green complex Redan.

I for one would love to see cataloging of GCA patterns along the lines of what Design Patterns: Elements of Reusable Object-Oriented Software by Gamma, Helm, Johnson, and Vlissides did for software design. This book made a huge contribution to work in software development.

Jason,

Thanks for the pointer. I had not seen that before.

However, I am trying to get more depth. Bill Coore is famous for spending a lot of time at a site finding holes. What are that patterns that he sees that makes him choose a particular hole? Are they the same patterns that others see? Has anyone cataloged such a thing? Perhaps naming an example like Redan would mislead you as to what I am looking for. Surely Bill Coore is not setting out to recreate Redan, Alps, Eden, etc. as CB MacDonald and others did.

one (of many) brilliant part of Alexander's Pattern Language is in the preface of the book, where he states (paraphrasing here...) that the patterns are merely a guide, and that the designer applying each pattern, or group of patterns, is not only able, but encouraged to push their definitions, in order to fit the selected patterns to problem at hand...

this is where i see patterns continually applied in gca, whether they are catalogued or not...

Which problem does the Redan solve?
Some of the problems the patterns would solve in GCA are are always the same: What type of hole would fit into a routing here? What type of hole would be of strategic interest?, etc. Perhaps the most significant problem is the terrain and features of the land to be utilized for the course. If the land is eastern SD farmland, then satisfactory solutions begin to require a lot of earth movement and the Redan certainly solves the strategic interest problem.

There is a great thread from last August where Jeff Brauer lists and analyzes basic GCA strategies.  If I can find it I will plug it in.

Here it is:

George,

Here is my take, from my Cybergolf series.

Strategy starts at the pro shop, where players “buy a better game.”  But, smart on course strategy lowers score, with obvious cost advantages and better odds of success!  

Golfers make strategic decisions, even on holes without strategic qualities.  They must:

•   Know their distance with each club
•   Adjust for wind, uphill/downhill conditions, and slopes that affect distance or roll.
•   Account for daily variances in weather, hole locations, and game situations
•   Aim correctly, allowing for shot pattern, wind, and lie.  Trajectory and spin control is becoming as or more important than curving the ball these day......

For many, those demands are enough – or too much!  Nonetheless, strategic choices make it even more fascinating!  I exploit the universal desire for lower scores* by placing hazards requiring mental agility to conquer.  It starts on the tee shot, which all fall under these classifications:

“Heroic”

Heroic holes have dramatic options of driving over non recoverable hazards, versus playing to a safe fairway.  Examples include:

o    “Cape Holes,” with a diagonal carry over lake, or

o    “Challenge Fairways”, where an alternate fairway straightens/shortens the hole significantly.

Heroic holes work well downwind, tempting golfers to carry hazards, and increasing the value of open front greens, as the wind will reduce approach shot backspin.  These holes reward length, so I limit their use.

“Strategic”

Strategic tee shots come in a few different philosophical types:

•   “Position paradox”

You really need to find a certain fairway position, but really, really, want to avoid surrounding hazards!

•   “Variable”

Daily wind conditions and pin locations dictate possible advantages.  These require wide fairways, staggered bunkering, and greens with multiple pin locations.

•   ”Democratic”

These accept most shot patterns, with advantage coming from playing to your strength.

•   “Diminishing Returns”

Gradually narrowing fairways create dilemmas between the advantages of shorter approaches versus missing fairways.  On long holes, the length advantage is usually very strong; but on short holes, it’s less.  

These work best on medium par 4’s, and reachable par 5’s.  

“Penal”

Penal tee shots come in three varieties:

•   “Forced Lay Ups” caused by full crossing hazards limiting full tee shot distance.  Up or downwind, or downhill complicates getting close to the hazard without going in.

•   “Forced Carries caused by full crossing hazards requiring minimum length tee shots to reach the fairway.  These are sometimes necessary, but provide little strategy, so I use them rarely.

•   “Bottleneck“, requiring shot placement in a narrow landing area, surrounded by trouble.  

“Hybrid”

There are other tee shot strategies, which have as much “challenge” as strategy:

•   “Cross Slope fairways” dictating “high side” play, or a combination of flat areas and rolls providing advantages in limited areas.

•   “Forced Curve.”  Ground hazards suggest curved shots.  Well placed trees dictate them!  Golf shots reach horizontal and vertical apex 70% through flight.  Encroaching trees 180-200 yards from the back tee best accommodates curved tee shots, but require wide fairways, so all shot patterns can hit some part of the fairway.

•   “Open Field” with little difficulty, providing either equal access from everywhere (useful on public courses and opening holes), or with a green creating “delayed penalty” from certain areas.  

•   “Battlefield” with randomly strewn hazards.  Little used, unless some areas have fewer hazards than others to create some strategy.

With an infinite number of subtle variations on these tee shot concepts, it’s a shame that so many courses have blandly repetitive tee shots, when they could easily have 14 distinct full tee shots!

The words "Brauer" and "great thread" have rarely and probably never before been associated on this site have they?  I guess those basic strategies work to answer the question, but I assumed you are referring to another thread where I categorized strategic elements as "inside-inside" "inside-outside" both sides- no side (referring first to the fw hazard and then the green.

To answer the current question, my first impression wasn't strategies, although I think that qualifies.  It was about the general sameness of green and tee sizes, as they are a reflection of the minimum possible sizes for good maintenance practices.  

To a lesser degree, approximate bunkers sizes, both from the visual aspects of how much the sand to green ration ought to be (sand shouldn't often dominate the target) but also in creating bunker lobes and slopes that can be maintained by a power rake (generally about 16' diameter minimum and about 25% max slope, with less preferred)

I suppose the standard Par 72 course of about 7000 yards could be called a repetitive design solution.

Even things like bridges, as a way to mitigate environmental concerns fall into the "standard" solution category for me, as do the cart paths they carry......

My last project was derailed by a guy who was more interested in the theory of design patterns than in designing software, so I need to clarify this buzzword . . .

A design pattern solves a specific, repeating, and unglamorous problem. Saying that the Redan template hole is a design pattern is like saying that Microsoft Word implements the "word processor" design pattern. The Redan does not answer a question, it creates the problem "I have to put this Redan somewhere". It can be thus labeled as an anti-pattern.

Jeff Brauer is on the money here. "How can I build this bunker so that A- the sand to green ratio is correct and B -it is maintainable." He has a bag of tricks for that, his design patterns.

Here's a golf course architecture design pattern called the "Pile" pattern, which can be deployed when the ground where you want your fairways is solid granite.

Rich -

You know, when I first played Belgrade Lakes, I was put off by the aesthetics of the rockpiles, which are numerous and vast.

But once you krush a drive into a pile and watch the astounding "rub of the granite", you will see that they are a delightfully random hazard. Everything from lost ball to an additional eighty yards.

Garland:

From the way you describe it, what you call "design patterns" I just call basic "strategic concepts". Either way the architect is just trying to do things or make things that will make or allow various golfers to think certain things and do certain things----eg (concepts).

I think design patterns go a little farther than strategic concepts. Design patterns describe when to apply the strategic concept. When given the flat SD farmland, design patterns have less influence on which strategic concept to apply.

The more I think about it, the more I think its a response to technology, rather than strategy that is the best answer.

The reason buildings get certain dimensions are the requirements for studs 16" on center for structural reasons, or similar dimensions when using curtain wall technology in skyscrapers.

Golf courses acquire certain basic dimensions that have been set for several decades.  They have been modified (for example, when irrigation systems came out with approximately 70 spaced sprinklers, greens now had a maximum width in at least one direction to accomodate those) that respond to these.  As mentioned elsewhere, the cost of USGA greens also began to reduce "standard" green size to the minimum a superintendent could maintain.

Strategic implications are add ons to the basic structure of "building" a golf course that can survive, which can and should change each time.

My last project was derailed by a guy who was more interested in the theory of design patterns than in designing software,

I think the number of software projects that have been derailed by design patterns is truly insignificant to the number of software projects that are derailed in general. So I don't see your need to bring that up here.

so I need to clarify this buzzword . . .

A design pattern solves a specific, repeating, and unglamorous problem. Saying that the Redan template hole is a design pattern is like saying that Microsoft Word implements the "word processor" design pattern. The Redan does not answer a question, it creates the problem "I have to put this Redan somewhere". It can be thus labeled as an anti-pattern.

Isn't this a bit myopic? When the terrain of the land matches the terrain of a classical Redan hole, isn't one answer to what strategic design pattern fits here the Redan? I think you are approaching this discussion from the viewpoint of an architect that moves a lot of dirt as opposed to a "renaissance" or "minimalist" viewpoint.

Jeff Brauer is on the money here. "How can I build this bunker so that A- the sand to green ratio is correct and B -it is maintainable." He has a bag of tricks for that, his design patterns.

Granted, there a lot of design patterns that real golf course architects have to deal with beyond those that we armchairs take the most interest in (and Jeff would be one of the first to point that out), but a catalog of such design patterns would be of interest to a much smaller audience.

Here's a golf course architecture design pattern called the "Pile" pattern, which can be deployed when the ground where you want your fairways is solid granite.

BTW, how is golf in Maine? Is the snow gone yet?

Which Redans are built on naturally occuring "Redan-like" terrain? I honestly don't think I have seen one or a picture of one.

Garland -

I am not convinced that laying down a Redan hole on land perfectly suited to a Redan hole either solves a problem or leverages a design pattern.

People who use software and buildings generally remain ignorant of the design pattern minutiae that contribute to pleasant experiences with software and buildings. Likewise with golf course architecture.

Armchair architects don't walk around cities and say "here is an example of the cathedral pattern and here is an example of the skyscraper pattern".

Hi,

I'm bumping this because i feel like Garland was onto something here, and the thread got offtrack (perhaps we should even start a new one?).  The inherently blurry definition of "pattern" is perhaps the culprit.  

If you refer back to Garland's first post he cites Christopher Alexander's "A Pattern Language"... well, the inspiration for me bump this thread was that I recently found an abbreviated version of "A Pattern Language" online, for reference:  

http://downlode.org/Etext/patterns/index.html

This is (arguably) key reading for designers, and placemakers.  There's no question that there has to be some sort of crossover to gca - which i think is what Garland is after.  The book is littered with diagrams, which make many of the patterns crystal clear - unfortunately unavailable in the online version.

The key here I believe is the definition of "pattern" - Garland quoted Alexander saying:

"Each pattern describes a problem which occurs over and over again in our environment, and then describes the core of the solution to that problem, in such a way that you can use this solution a million times over, without ever doing it the same way twice."

If i could BOLD, i'd highlight "...without ever doing it the same way twice."  Keep that in mind.  

You'll notice in Alexander's patterns (of which there are 253, but by definition, there could potentially be thousands...) work at different scales - starting with large, sweeping regional scales, and moving in slowly to detailed patterns, specifying materials and even dimensions.  

Alexander states that his patterns may or may not work alone, but are most effective when used in conjunction with patterns at other scales... for example - Pattern 157: Home Workshop - may be also used in part of Patterns: House Cluster (37), Your Own Home (79), Scattered Work (9), Network of Learning (18), Men and Women (27).

A key to interpretting this is that like in all things design, there are no hard and fast rules and that these patterns were written purposely vague in some cases to encourage personal interpretation... the designer can pick and choose as he/she sees fit, using pattern(s) in whole, or in part...

So.... now the question is, how do we apply Alexander's placemaking theory to golf course architecture?  Its easy to look at golf course design and apply some of Alexander's patterns.. for example, a new urbanist type of approach to a golf development might incorporate parts of Pattern 3 - City/Country Fingers, 30- Activity Nodes, 31- Promenade, 37- Cluster Houses, 67- Common Land etc.

To paraphrase Garland's question - are there any golf specific patterns that can be developed?  I think Garland may have missed the mark with identying template holes as patterns, however, the theory of a "Cape"-style tee shot may work...

Perhaps if we look at different scales, much like Alexander does - start wide - ie/ patterns of site selection, routing... and then move in to detailing... I think something like "bunker edges" could qualify.

I'm not exactly sure where this is going.... and much of this post is a bit rambling... Maybe i'm wayyy off base, but I enjoy this kind of pseudo-intellectual theorizing.

Would a minimalist have more need or less need for design patterns? I.e., given the terrain you have to work with, would you need to use cataloged patterns for solving the problems of the terrain. Or, would you be looking for unique and innovative answers to each situation. Is the Old MacDonald's course a minimalists application of design patterns? Whereas, Pacific Dunes a minimalist search for innovative answers?
