For hosting our frontend application we have been using static hosting from surge. For our backend application we will be using Heroku because of their free tier and overall simplicity in usage.
First you will need to sign up for an account. We will be using some plugins which technically may cost money if you exceed the free tier. Therefore they require a credit card, but so long as you stay in the free tier they will not charge you -- I have never been charged. After you have an account and are signed in you need to download the Heroku Toolbelt. We use Git to talk to Heroku.
You will need to be logged in to Heroku to proceed:
heroku login
Remember to have node_modules in your .gitignore file for every git repo you use. You can use my gitignore as an example.
To deploy to Heroku start by navigating to the directory of your backend application. In this directory you should be able to start your server, i.e., it's the directory with package.json.
You will want to come up with a name for your application. Note that
later in the course we will create new applications so as to not "stomp" over previous assignments.
So the name you pick here will not necessarily be the final name of your final social networking app (and we can always change the name later). In the example below, I have named my application ricebookapp
, which should be replaced with your chosen name, or leave blank and Heroku will assign a name for you.
These names are globally unique, therefore your name may have already been chosen, so pick another or let Heroku give you a name.
git init heroku create ricebookapp echo web: npm start > Procfile git add . git commit -m 'initial commit' git push heroku master heroku ps:scale web=1
Now your soon to be app is hosted and running on Heroku. Navigate to, e.g., https://ricebookapp.herokuapp.com to see it.
What did these steps do? We started by creating a new git repository. We then created a new Heroku application that was tied to it. (The order of these operations matters because if you create the Heroku app first then it will not be attached to the git repo. If you did this, then to fix it execute heroku git:remote -a ricebookapp
) Next we defined the command that Heroku will execute to start our application (Procfile). Notice that it executes "npm start"
Next we add all of our files to the git repo.
We commit the changes.
Finally we push to the remote Heroku git master. Heroku builds our application and spins up the Node server.
For the inclass exercise, submit a file named README.json that has the following contents (replaced with *your* values of course)
{ "netid": "sep1", "backend": "https://ricebookapp.herokuapp.com" }

CAAT.Actor
Actor Events
An Actor instance has mouse events enabled by default. The mouse control methods are the following:
- function mouseEnter(mouseEvent)
Triggered whenever the mouse enters the rectangular area of an Actor. The Actor can be transformed by rotations and scales. That means that CAAT will perform perfect pixel collision detection so the mouse arrow must be inside the contour of the Actor despite the transformation applied to id. - mouseExit(mouseEvent)
Exactly like in mouseEnter, but when leaving the Actors contour. - mouseMove(mouseEvent)
Triggered whenever the mouse arrow traverses inside the Actor's contour. - mouseDown(mouseEvent)
Triggered whenever we press the mouse button inside the Actor's contour. - mouseUp(mouseEvent)
Same as mouseDown but when releasing the mouse button. - mouseClick(mouseEvent)
Triggered whenever a click has been generated on the Actor. That means that previously a mouseDown and then a mouseDown have been triggered on the Actor. - mouseDblClick(mouseEvent)
Same as mouseClick but double click. - mouseDrag(mouseEvent)
Triggered after we perform an equivalent to mouseMove after having done mouseDown. After dragging, when releasing the mouse button, only mouseUp will be triggered avoiding to trigger mouseClick event.
All these methods receive a unique parameter of type CAAT.MouseEvent. It contains the following information:
- screenPoint
The 2D point of the screen coordinate that originated the mouse event. - x,y the same as screenPoint but w/o being wrapped in an object.
- point
The 2D point of local Actor coordinates. Remember that local coordinates are from (0,0) to actor's (width,height). These 2D point is derived from the screenPoint. - modifiers
Modifiers will tell you whether some special keys where pressed during the mouse input. The CAAT.MouseEvent class has some methods to check for these special keys. - time
The Scene time (more on this later) at which the event was produced. - source
The actor the event was produced at.
If an Actor instance is not supposed to process input from mouse, a call to enableEvents(false) must be explicitly called. This method can be called at any given time with a boolean parameter to set or reset mouse handling.
Two methods of CAAT.Actor instances will change default mouse event handling methods for others:
- function enableDrag(). Will set mouse methods to allow an actor instance's drag. Some drag modifiers such as shift, control and shift+control will change actor's rotation and scale.
- function setAsButton(). Will set mouse methods to allow a given actor behave as a button.
Other input types such as keys and accelerometer are handled directly by CAAT.Director instances.
Example
In this example, you can see some rectangle-shaped actors with other rectangle child inside.
A CAAT.ActorContainer can contain any number of Actors and hence any number of other ActorContainer instances.
var director_1 = new CAAT.Director().initialize( 600,120, document.getElementById('_c1')); var scene_1= director_1.createScene().setFillStyle('#fff'); // make the scene clear background and draw a black rectangle scene_1.paint= function(director, time) { var ctx= director.ctx; ctx.fillStyle= this.fillStyle; ctx.fillRect(0,0,this.width,this.height); ctx.strokeStyle= '#000'; ctx.strokeRect(0,0,this.width-1,this.height-1); } // create six actors for this scene. for(var i=0; i<6; i++ ) { // rectangle shaped actors of 80x80 pixels. var s = 80; // containers can contain other actors or containers. var _c1_container = new CAAT.ActorContainer(). setBounds(i*100+10, 20, s, s). setRotation( Math.PI*2*Math.random() ). setFillStyle('#ff3fff'). enableDrag(); _c1_container.name = 'rectangle'+i; // set container paint routine to draw an arrow _c1_container.paint= function(director, time) { var crx= director.ctx; // fill actor crx.fillStyle= this.fillStyle; crx.fillRect(0,0,this.width,this.height ); // outline it. crx.strokeStyle= 'black'; crx.strokeRect(0,0,this.width,this.height ); // draw a white arrow. just to point where position 0,0 is. crx.strokeStyle='white'; crx.beginPath(); crx.moveTo(5,10); crx.lineTo(20,10); crx.lineTo(15,5); crx.moveTo(20,10); crx.lineTo(15,15); crx.lineWidth=2; crx.lineJoin='round'; crx.lineCap='round'; crx.stroke(); }; // add actor to scene. scene_1.addChild(_c1_container); // create a container. var _c1_container_child= new CAAT.ActorContainer(). setBounds(s/2,s/2,s/4,s/4). setRotation( Math.PI*2*Math.random() ). setFillStyle('#00ff00'). enableDrag(); // set a custom paint function for children inside containers. _c1_container_child.paint= function(director,time) { // call default container paint method. CAAT.ActorContainer.superclass.paint.call(this,director,time); var ctx= director.ctx; // fill a white circle of 10x10 pixels at position 2,2 // just to show where 0,0 is positioned on screen. ctx.fillStyle='white'; ctx.beginPath(); ctx.arc(7,7,5,0,2*Math.PI,false); ctx.fill(); } // add this container as a child of the previous created container. _c1_container.addChild(_c1_container_child); } // set animation to 10fps. CAAT.loop(10);

Reviewed by Harvey Karten Artisan Entertainment Director: David Atkins Writers: David Atkins, story by Atkins and Paul Felopulos Cast: Steve Martin, Helena Bonham Carter, Scott Caan, Laura Dern, Elias Koteas, Lynne Thigpen Screened at: Review 1, NYC, 10/10/01
Don't you just hate going to the dentist? Scripters Paul Felopulos and David Atkins have conjured up one patient who likes going so much that when she needs a root canal, she not only looks forward to getting it treated but seeks out four dentists before she allows any of them to do much with the decayed molar. Going to four dentists for the love of meeting and talking with them? This has got to be a fictional character. To be fair, though, young Susan Ivey (Helena Bonham Carter) has an ulterior motive. She does not hesitate to seduce them, at least digging her claws into DDS Frank Sangster (Steve Martin), but sex is not her ultimate objective. Susan is a drug addict and dentists carry refrigerators full of chemicals from novocaine to nitrous to injectable cocaine to demerol.
"Novocaine" is a dark comedy featuring one of our top comics, Steve Martin, in a role not as sinister as the one he played in David Mamet's marvelously written thriller "The Spanish Prisoner" nor as flat-out hilarious as the dentist in Frank Oz's "Little Shop of Horrors." He's somewhere between, first shown as a highly successful practitioner engaged to anal-compulsive hygienist Jean Noble (Laura Dern) with Lynne Thigpen as his no- nonsense but affectionate receptionist. He becomes the victim of a series of mishaps that ultimately finds him a suspect for murder, a dilemma he could have avoided had he not succumbed to the temptation in the form of an unstable, conniving woman whose eroticism charms him because Susan is the opposite of his compulsively neat and orderly fiancee.
Though David Atkins's film is overplotted, with the director juggling several conceits including sibling dysfunction. Susan has an incestuous thing going with her wastrel brother Duane (Scott Caan) while Dr. Sangster feels an obligation to care for his unsuccessful, envious, drug-and-drink addicted sib Harlan (Elias Koteas). "Novocaine" is frequently as giddy as a ride on nitrous--which does not come close to dulling the pain felt by the good doctor as his life takes on the decay for which rotting teeth provide an apt metaphor.
Czech-born photographer Vilko Filac peppers the narrative with x-ray shots of patients' teeth and entire heads, skeletal figures lurid enough to scare the kids at Halloween while a non-intrusive, effective score is provided by "Edward Scissorhands" musician Steve Bartek.
Atkins, whose script for "Arizona Dream" dealt with the loss of the American Dream, plays winningly with a similar theme this time around as well, highlighting a person who has it all and yet is vaguely dissatisfied and helps bring disaster upon himself when his brain transfers to a position below his waist.

command is not recognized as an internal or external command, operable program or batch file
This stderr
standard error stream is a common Windows command line issue experienced among new
programers, and we are all to common with it. But what does it actually mean?
The text "command is not recognized as an internal or external command" refers to executables or .exe
files. This is stating that there is no .exe
file with that name in the current directory, or in your
%PATH%
directories. A %PATH%
directory is where command prompt looks for executables or
.exe
files when you type in a command. The most well known %PATH%
directory is the
C:\Windows\System32
directory where programs such as echo
and shutdown
are
located. Therefore, if you type in echo "Hello World!"
, you are actually calling the
echo
program from within C:\Windows\System32
with the command line argument of
"Hello World!"
. Hence why if you delete this directory everything stops working.)
The text "or batch file" inherits all the same ideas as the executables, but also contains the idea that you can
run batch files (.bat
and .cmd
) files without specifying the .bat
extension
to the file path.
e.g. helloWorld.bat
can be called by helloWorld
$
at the start of the command, remove it and any leading spaces until the first
alphanumeric character (as the $
character represents that you should run the following from the
command line / terminal)
.bat
download the script first%PATH%
environment variables contain the path to the executable If all else fails, you may need to try a different solution.

pkcs11.confpkcs11.conf — Configuration files for PKCS#11 modules |
A complete configuration consists of several files. These files are
text files. Since p11-kit
is built to be used in all
sorts of environments and at very low levels of the software stack, we
cannot make use of high level configuration APIs that you may find on a
modern desktop.
Each setting in the config file is specified consists of a name and a value. The name is a simple string consisting of characters and dashes. The name consists of alpha numeric characters, dot, hyphen and underscore.
The value is specified after the name on the same line, separated
from it by a :
(colon). White space between the
name and value is ignored.
Blank lines are ignored. White space at the beginning or end of
lines is stripped. Lines that begin with a #
character
are ignored as comments. Comments are not recognized when they come after
a value on a line.
A fictitious module configuration file might look like:
module: module.so # Here is a comment managed: true setting.2: A long value with text. x-custom : text
Each configured PKCS#11 module has its own config file. These files can be placed in various locations.
The filename of the configuration file may consist of upper and lowercase letters
underscore, comma, dash and dots. The first characters needs to be an alphanumeric,
the filename should end with a .module
extension.
Most importantly each config file specifies the path of the PKCS#11 module to load. A module config file has the following fields:
|
The filename of the PKCS#11 module to load.
This should include an extension like If this value is blank, then the module will be ignored. This can be used in the user configs to override loading of a module specified in the system configuration. If this is a relative path, then the module will be loaded from the default module directory. |

Each configured PKCS#11 module has its own config file. These files are placed in a directory. In addition a global config file exists. There is a system configuration consisting of the various module config files and a file for global configuration. Optionally each user can provide additional configuration or override the system configuration.
The system global configuration file is usually in
/usr/local/etc/pkcs11/pkcs11.conf
and the user global
configuration file is in ~/.config/pkcs11/pkcs11.conf
in the
user's home directory.
The module config files are usually located in the
/usr/local/etc/pkcs11/modules
directory, with one configuration
file per module. In addition the ~/.config/pkcs11/modules
directory
can be used for modules installed by the user.
Note that user configuration files are not loaded from the home directory if running inside a setuid or setgid program.
The default system config file and module directory can be changed
when building p11-kit. Always
lookup these paths using
pkg-config
.

67 Ugandans arrested in gay-friendly bar charged with 'nuisance'
Sixty-seven people arrested by police in a Kampala bar popular with gays were charged with "common nuisance" on Tuesday, but rights activists said it was a bid to intimidate the LGBT community.
The police raided the Ram Bar in the heart of the Ugandan capital on Sunday and arrested 125 people, 58 of whom were subsequently freed.
Police spokesman Patrick Onyango initially told AFP they did not know the bar was hosting an LGBT event on the night of the raid, which was targeted at illegal tobacco and opium use.
The 61 men and six women were subsequently charged with the unrelated offence of common nuisance.
Clare Byarugaba from the human rights organisation Chapter Four Uganda told AFP that the police deliberately targeted the bar.
"The police knew who they would be targeting. It's a crackdown on any space seen to be LGBT-friendly," Byarugaba said.
"This was intended to intimate and scare LGBT individuals."
Human rights lawyer Patricia Kimera, who represented many of the accused in court, told journalists that her clients had not received a "fair hearing".
"Their rights have not been respected," she said. "These people were caught having fun in a bar. There's no evidence they were a common nuisance."
Uganda has strict anti-gay legislation but there have been no prosecutions for consensual same-sex acts in recent years.
However acts deemed "against the order of nature" can lead to life imprisonment.
At the end of October, 16 Ugandan LGBT activists were subjected to forced anal examinations after being arrested, according to the country's leading gay rights organisation.


FFT : Fast Fourier Transform Unit
Input Types :
Output Types :
SampleSet,
ComplexSpectrum,
ComplexSampleSet,
Spectrum,
Spectrum2D
Date : 09th March 2001
If the user chooses automatic operation in the user interface window, and if the input is a Signal or Spectral data type, then the unit automatically performs the correct type of transform. Therefore, two successive applications of the FFT unit, starting with either a SampleSet or a ComplexSpectrum, will produce a final output identical to the original input, to within roundoff error. Here is how the unit makes its choices:
If the input is a Spectral data type, FFT performs the direct FFT. The output data type is a Spectrum or ComplexSpectrum. A normalization is applied to ensure that the FFT output is a sampled representation of the continuous Fourier transform X(f) of the function of time x(t) represented by the input set, according to the following equation
X(f) = integral[ x(t) exp( -2 Pi i f t )] dt.
This transfroms the input signal from a time representation to a frequency one. The output data is a one-sided representation of the spectrum (negative frequencies are not stored) if the input is a SampleSet. The output is normally a ComplexSpectrum, but if the input is a ComplexSampleSet with sufficient symmetry, the output will be a real Spectrum. For display or further work, the ComplexSpectrum can then be transformed into an amplitude spectrum or a power spectrum.
If the input is a Spectrum or a ComplexSpectrum, the unit performs the inverse FFT. The output data type is a SampleSet or a ComplexSampleSet, depending on whether the input set is one-sided or two-sided and what symmetry it has. A normalization factor ensures that the inverse FFT output is a sampled representation of the continuous data set x(t) represented by the following continuous transform of the input set X(f):
x(t) = (1/ 2 Pi ) integral[ X(f) exp( 2 Pi i f t )] df.
This transforms the input spectrum back to the time domain.
If the user chooses direct or inverse operation, then the unit ignores the type of the input data set and performs the requested operation. It applies normalizing factors (1/N) if the appropriate factor is chosen.
For some purposes, a windowing function should be applied to data before it is transformed. The user interface gives a choice of some standard windows. The choices are Bartlett, Blackman, Gaussian, Hamming, Hanning, and Welch. These are described in the help file for WindowFnc.
For convenience, the user has an option to maximize speed of the transform in the 1D case, or to minimize storage. The minimum storage option produces a one-sided output, while the maximum speed option produces a two-sided output.
For efficient operation, it is best that the input length should be a power of 2. The unit allows the user to choose that the input is padded to the nearest larger power of two.
The FFT's parameter window allows the user to choose the type of operation of the transform. There are 5 modes : Automatic, Direct, Direct/normalizated(1/N), inverse or inverse/normalized(1/N). For one-dimensional data sets there are three further options. One is to optimize the speed of the calculation or the storage space of the result. A second option allows the user to specify the windowing function required (if any). The third is a choice of whether the unit should automatically pad out with zero's to the right when applying the FFT.

MathJax comes with a number of pre-defined configuration files in the MathJax/config directory. The default.js file contains nearly all the possible configuration options together with comments explaining them, so you can use that file to customize MathJax to your needs. Simply load it via
<script type="text/javascript" src="path-to-MathJax/MathJax.js?config=default"></script>
where path-to-MathJax is the URL to the MathJax directory on your server or hard disk.
The remaining files are combined configuration files that include not just configuration parameters but also the files that MathJax would need to load for those configurations. This means MathJax will have to load fewer files, and since each file access requires establishing connections over the network, it can be better to load one larger file than several smaller ones. See Loading and Configuring MathJax for more details about how to load configurations, and how to modify the parameters for a configuration file.
The following sections describe the contents of the combined configuration files. Each comes in two flavors: a standard version and a “full” version. The standard version simply defines the output processor(s) that are part of the configuration, but doesn’t load the code that implements the output processor; the full version loads the complete output processors, so everything that MathJax needs for the page should be loaded up front, and there will be no delay once the page is ready to be processed. To obtain the “full” version, add -full to the end of the configuration file name.
This configuration file is the most general of the pre-defined configurations. It loads all the important MathJax components, including the TeX and MathML preprocessors and input processors, the AMSmath, AMSsymbols, noErrors, and noUndefined TeX extensions, both the native MathML and HTML-with-CSS output processor definitions, and the MathMenu and MathZoom extensions. It is equivalent to the following configuration:
MathJax.Hub.Config({
config: ["MMLorHTML.js"],
jax: ["input/TeX","input/MathML","output/HTML-CSS","output/NativeMML"],
extensions: ["tex2jax.js","mml2jax.js","MathMenu.js","MathZoom.js"],
TeX: {
extensions: ["AMSmath.js","AMSsymbols.js","noErrors.js","noUndefined.js"]
}
});
In addition, it loads the mml Element Jax, the TeX and MathML input jax main code (not just the definition files), as well as the toMathML extension, which is used by the Show Source option in the MathJax contextual menu. The full version also loads both the HTML-CSS and NativeMML output jax main code, plus the HTML-CSS mtable extension, which is normally loaded on demand.
See the tex2jax configuration section for other configuration options for the tex2jax preprocessor, and the TeX input jax configuration section for options that control the TeX input processor. See the mml2jax configuration section for other configuration options for the mml2jax preprocessor, and the MathML input jax configuration section for options that control the MathML input processor. See MathJax Output Formats for more information on the NativeMML and HTML-CSS output processors. See the MMLorHTML configuration section for details on the options that control the MMLorHTML configuration.
This configuration file is for sites that only use TeX format for their mathematics, and that want the output to be as close to TeX output as possible. This uses the HTML-CSS output jax (even when the user’s browser understands MathML). The user can still use the MathJax contextual menu to select the NativeMML output jax if they desire.
This file includes all the important MathJax components for TeX input and output, including the tex2jax preprocessor and TeX input jax, the AMSmath, AMSsymbols, noErrors, and noUndefined TeX extensions, the HTML-with-CSS output processor definition, and the MathMenu and MathZoom extensions. It is equivalent to the following configuration:
MathJax.Hub.Config({
jax: ["input/TeX","output/HTML-CSS"],
extensions: ["tex2jax.js","MathMenu.js","MathZoom.js"],
TeX: {
extensions: ["AMSmath.js","AMSsymbols.js","noErrors.js","noUndefined.js"]
}
});
In addition, it loads the mml Element Jax and the TeX input jax main code (not just the definition file), as well as the toMathML extension, which is used by the Show Source option in the MathJax contextual menu. The full version also loads the HTML-CSS output jax main code, plus the HTML-CSS mtable extension, which is normally loaded on demand.
See the tex2jax configuration section for other configuration options for the tex2jax preprocessor, and the TeX input jax configuration section for options that control the TeX input processor. See MathJax Output Formats for more information on the HTML-CSS output processor.
This configuration file is for sites that only use MathML format for their mathematics. It will use MathML output in browsers where that is supported, and HTML-CSS output otherwise. The user can still use the MathJax contextual menu to select the other output format if they desire.
This file includes all the important MathJax components for MathML input and output, including the mml2jax preprocessor and MathML input jax, the NativeMML and HTML-CSS output processor definition files, and the MathMenu and MathZoom extensions. It is equivalent to the following configuration:
MathJax.Hub.Config({
config: ["MMLorHTML.js"],
jax: ["input/MathML","output/HTML-CSS","output/NativeMML"],
extensions: ["mml2jax.js","MathMenu.js","MathZoom.js"]
});
In addition, it loads the mml Element Jax and the MathML input jax main code (not just the definition file), as well as the toMathML extension, which is used by the Show Source option in the MathJax contextual menu. The full version also loads both the HTML-CSS and NativeMML output jax main code files, plus the HTML-CSS mtable extension, which is normally loaded on demand.
See the mml2jax configuration section for other configuration options for the mml2jax preprocessor, and the MathML input jax configuration section for options that control the MathML input processor. See MathJax Output Formats for more information on the NativeMML and HTML-CSS output processors. See the MMLorHTML configuration section for details on the options that control the MMLorHTML configuration.
This configuration file is essentially the same as TeX-AMS-MML_HTMLorMML except that it includes options that are designed for assistive technology, particularly for those with visual challenges. It is equivalent to the following configuration:
MathJax.Hub.Config({
config: ["MMLorHTML.js"],
jax: ["input/TeX","input/MathML","output/HTML-CSS","output/NativeMML"],
extensions: ["tex2jax.js","mml2jax.js","MathMenu.js","MathZoom.js"],
TeX: {
extensions: ["AMSmath.js","AMSsymbols.js","noErrors.js","noUndefined.js"]
},
NativeMML: { showMathMenuMSIE: false },
menuSettings: { zoom: "Double-Click" },
errorSettings: { message: ["[Math Error]"] }
});
This turns off the MathJax contextual menu for Internet Explorer, since it can interfere with some screen readers. It also sets the zoom trigger to double-click, so that readers can see a larger version of the mathematics but double-clicking on any equation.
In addition, it loads the mml Element Jax, the TeX and MathML input jax main code (not just the definition files), as well as the toMathML extension, which is used by the Show Source option in the MathJax contextual menu. The full version also loads both the HTML-CSS and NativeMML output jax main code, plus the HTML-CSS mtable extension, which is normally loaded on demand.

At Zayd Limited, we drive efficiency at every stage of our projects, constantly striking the right balance between quality and savings. Our in-house cost management service provides impartial, specialist advice on the diverse cost elements of construction projects. Zayd takes a modern approach to what is often viewed as an archaic profession. We engage with design teams and contractors to ensure every project realises the best value from the construction costs, and we market test to a minimum of 70% of the cost plan value at each stage. Our in-house cost management teams often works with other parts of Zayd to provide cost planning advice for construction management, project management, fixed price schemes, roll out programmes and public sector frameworks.
Certainty of delivery lies at the heart of project management. At Zayd, our project management experts offer a flexible and highly bespoke service based upon a robust and wellproven formula for delivery. Working alongside our clients, we adopt a value-driven approach to defining and articulating their business and project objectives before identifying the most effective means to deliver. We provide a full spectrum of project management services from the preparation of business cases and the development of organisational frameworks to straightforward delivery.
Our programme management experts have the experience and perspective to define a course of action while managing risk and cost; the leadership to maintain complete control and transparency across the process; and the passion and enthusiasm to drive value at every turn. In delivering our programme management service, we work with client teams to identify and clarify their goals, and understand their specific challenges and drivers for change. We then define a rigorous programme and execute it from within to ensure it is deeply embedded in the organisation’s culture from the outset. With the ultimate aim of successfully delivering programmes to the satisfaction of all stakeholders, we carefully manage risks and costs, maintaining complete control and unwavering leadership throughout the process.
We were founded on the belief that the construction industry was hungry for a more open and collaborative approach to procurement and delivery. Since then, we have been a leader in construction management, and have expanded our service offer to include the same thinking on fixed price, contracting, and fit out. We provide construction services to clients both locally and internationally, delivering projects in a transparent and mutually beneficial manner. We partner with our clients, acting in their interest and managing every element of a project from programme to cost. Our experts in construction management, contracting and fit out understand what it takes to ensure certainty of delivery, and challenge and innovate to deliver best quality on time and under budget.
Under a design and build strategy Zayd Ltd assumes the risk and responsibility for designing and building the project, giving the benefit of a single point of contact, in return for a fixed price lump sum. With a design and build delivery option, a professional design team would be selected to compile the client’s brief for the construction of the project. Once this brief is complete, a set of Employer’s Requirements would be prepared and issued to Zayd Ltd.
A method whereby Zayd Ltd is responsible for the total project from design through to the point where the key is inserted in the lock, turned and the facility is immediately operational.
We provide strategic management services informed by our experience both as a developer ourselves and as development manager for our clients. As a business our skills range from deal origination, land acquisition, securing planning, raising project finance and procuring teams to deliver our projects. We marry these development skills with our tried and tested management processes to successfully drive projects from inception to completion.
