Iâve recently become a signatory to SEMAT (Software Engineering Method and Theory). Theyâve been trying to get me to sign up for some time but I resisted so far. Why did I change my mind?
Originally, SEMAT was branded as âa revolution in software engineeringâ. I didnât like that: Iâm old enough to have seen plenty of ârevolutionsâ come and go. I did not want to go down the revolution road again. I decided to wait and see.
Now SEMAT has had its first workshop and seems to have made a good start. The revolutionary language has vanished. People that I greatly respect are involved. SEMAT now starts to look like an opportunity to make a difference.
Here is a quote from the workshop report that I really like, attributed to the late Robin Milner: “Language is the raw material of software engineering, rather as water is the raw material for hydraulic engineering“.
This week, Ivar asked me again: so this time I joined. Letâs see where it leads.

Those of you who are new to the real estate development business, need to understand what each Design professional contributes to the development team and the specific services they are capable of delivering for you.
Knowing what they do for you … what you are paying for is vital.
This is part of a series of articles I am writing for you to explain what each profession does in some detail.
Hydraulic Engineers
Most we know what an Architect does, or what a Structural Engineer does, but the hydraulic engineer is a bit of a puzzle.
When you hydraulic in the development business “think” pipes, “think” water, “think” gas.
In other words “think” of any material that has to be provided by pipes in a real estate development. Lock that into your brain and we’ll get to gripes with this service quickly.
If you are a resident of an apartment or a customer of a hotel, when you turn on a hot faucet (tap) you rightfully expect to feel hot water running into your sink soon.
Have you ever wondered how a person on the second floor or the sixtieth floor gets hot water on demand … or cold water for that matter.
Similarily, you can ask the same question about the liquid waste we humans produce in our residential accommodation.
You can add to that fire services and the sprinklers that keep us safe or the gas service if you want to cook on gas on the twentyfifth floor.
Do we want a swimming pool on the penthouse level or on the ground floor or do we want to recycle your waste water and use it to water the garden, then you’ll need an hydraulic engineer.
So the hydraulic engineer is pretty important to our health and lifestyle. If he did not exist, then high rise buildings would not exist.
So with that overview, let’s get into the detail.
On receiving the initial project brief, all aspects are examined in detail. The client’s brief is expanded, analysed and reports are written.
These reports allow the client the opportunity to evaluate all sections of the report, from a financial and technical point of view, in the full knowledge of the implications of all components of the hydraulic services.
Design co-ordination and control is maintained by regular in-house meetings, with the resultant elimination of site problems.
And the hydraulic engineer’s role can be summarised as:
Design documentation - services are drawn to scale.
Obtain all the necessary Authority Approvals.
Prepare the specification, schedules, quantities and estimates.
Complete the ‘As Constructed’ set of drawings.
Carry out all construction supervision and report.
,i>And the approach to their clients’ projects is:
* To be cost effective * To be efficient * To contain our latest design innovations

Heath, Nr Wakefield, North Yorkshire NMR Number: SE 32 SE 20.For centuries before piped water became generally available there occurred the occasional ambitious and ingenious scheme to bring it to the dwelling of the rich or influential.
In 1505 Richard de Wombwell, prior of Nostell, had conduit pipes laid from a well in Ryhill to take its water to the Priory (now a National Trust property). The well-head, recently restored, remains a feature of the landscape today.
About a hundred years later, this tower was erected above a natural spring and pumped fresh water via a water wheel to Old Heath Hall on the hill above. Mystery and wonder surround it as much today as it did in the 1600’s. Both modern and ancient pagans consider the spring sacred and Dame Mary is said to have dabbled in witchcraft. She asked that the room where she died (in 1662) in the old hall should be sealed. When it was unsealed, 50 years later, it is claimed that her ghost appeared and proceeded to haunt the surrounding heath.
Lady Bolles (1579-1662) owned the Heath estate from 1635 until her death at the age of 80, having purchased the Hall from the Kay family. First married to Thomas Jobson of Cudworth and, after his death, to Thomas Bolles of Osberton, Notts, she was created a baronetess by Charles I. Lady Bolles’s will, made in the year she died, refers to “the water tower or conduit, which she lately built, with the lead works and iron works belonging to it.”
The system was an unusual, perhaps even unique. The spring fed into a cistern from which, in turn, water flowed to power an 18-foot wheel. This provided the force to pump some of the water to the top of the tower from which height it would pass, probably by means of an overhead, lead-lined conduit, to the gateway at the old Hall.
Here, a further building, designed with the appearance of a gatehouse or lodge, held the huge storage cistern. This building, of a similar style and stonework to the water tower, like other of the outbuildings at the Hall, bears Lady Bolles’s coat of arms.
How long the system functioned is not known, but it may well have survived into the 19th century, though not, apparently, beyond the 1830s.
Lady Green, whose book, The Old Hall at Heath 1568- was published in 1889, refers to the tower and spring: “This spring used to be a very copious and never-failing stream, but it is much diminished by the sinking of a coal pit that tapped the water bearing stratum; nevertheless, it is excellent in colour and quality.”
The spring does, in fact, still flow with perhaps no greater loss of force than Lady Green records.
The tower stimulates considerable curiosity but its real nature is even more striking than its strange isolation suggests since it is a very early survival of English skill in hydraulic engineering.
