Factor affecting construction work scheduling

Developing a work plan for construction work in a contract required some basic important information. In a contract, it will always emphasize "TIME". In other words, TIME IS THE ESSENCE OF A CONTRACT. 

Generally, the term "time is the essence" simply means that a contract must have a starting date and closing date. This will be a guide for any work plan. Whatever scope of works is involved in order to complete a project, it shall be done within this period of time. This limited time available for any construction work in a contract will determine which construction method to be applied. The agreed construction period in a contract will also directly affect the type of machinery to be used and how much manpower need to be engaged. 

Despite the time frame given, manpower, and machinery we are chosen, when we plan a construction schedule, the bottom line is how much we are going to pay for all the costs. We shall be aware of the cost implications versus the agreed contract sum. In other words, when planing a construction work schedule, these major two (2) factors shall be balanced off. The two important factors are always "Time" and "Cost".

In general, to shorten the construction period, more manpower or machinery is required or more advanced construction technic is needed.

Managing delay in construction project.

Hai all.

In my previous posting, we discussed on the reasons of delay. The three type of delay are due to contractor fault, Client matters and unforeseen external factor.

Now in this posting, our the question is how to manage delay in construction? The discussion here will focused base on why delay happened? Who's fault is it?

Delay due to contractor own fault. This type of delay as mentioned in previous posting, contractor will not be granted extension of time (should the construction work overshoot the agreed construction period). Instead, contractor will be panelised as allow in the contract.

Hence how to avoid the delay beyong agreed construction period and avoid being panelised? There are  three (3) major method can be applied.

1. Working longer hours
2. Increase manpower, machine, plants and equipment
3. Change the construction method.

However, prior to deciding on which method to be use, contractor have to keep in mind that when they in the delay mode the most important issue is time and reputation.

As the remaining construction period getting shorter, contractor need to speed-up their works and to ensure that they completed the construction project as agreed in the contract. Thus the cost to expedite the construction work will be the second priority to be achieved. Nevertheless, as much as possible, contractor need to stay within the contract value to ensure or minimised losses due to the delay.

Delay caused by client and by external factor. This type of delay is much more easy to dealth with. Most contractor will prefer to apply extension of time(EOT). However proper documentation must be in-place. Prior to EOT application, contractor shall fulfill all of the procedure as mentioned in the contract. Some of the procedure are, to serve notice to client and to keep and produce any documents that can proved the delay was originated from client. Apart from that, contractor need to proved that the event will and already affected the critical path of the project.

Why construction project delay?

Hi readers, it has been quite sometime that this blog had been not updated. Today we meet again through this posting.

Construction delay, construction delay, construction delay !!!!

Why its happened to most of the contractor? What is the reason behind this delay?

First of all,what are the main reason for delay?
There are three (3) major type of delay.
1. Delay due to contractor fault.
2. Delay due to client reason.
3. Delay due to unforeseen external factor.

What are the root cause for construction delay due to contractor fault.

1. Fail to estimate and plan for the project budget and cash flow.
2. Fail to plan for a proper construction activities & work flow sequence
3. Fail to understand the construction procedure
4. Fail to procure required materials, machinery, equipments and construction experts in order to run constructions activities smoothly.
5. Lack of technical knowledge in the works undertaken.

Bear in mind, delay due to contractor own fault will not be granted for any extension of time. Extra working period taken by contractor to complete the project will be charge liquidated and ascertained damages by client. Not only that,  further delay to the project by contractor can caused stern action being taken against contractor up to termination of the contract and all termination.

How about delay on part of the client. Here are some of the reasons why.

1. Design change by client
2. Delay in payment to contractor.
3. Delay in client decision(s)
4. Additional scope of work requested by client.
5. Insufficient information given to contractor.

Delays due to client fault will always resulted in contractor being granted reasonable extra time to enable contractor complete the project.


Apart from contractor and client fault, unforeseen external factors also can be the reason for delay. In numerous occasions, reasons of nature and unforeseen human activities that can hindered both contractor and client to perform their duties diligently. What are the two mentioned before. Here are some of it.

Due to nature;
1. Extreme increment weather
2. Natural disaster

Cause by human;
1. Riots
2. Global or internal economy crisis
3. In sufficient workforce in construction industries
4. Sudden material shortage
5. Changes in government policies.
And etc.

Delay due to unforeseen external factors resulted to contractor being awarded extension of time or worst case scenario, mutual termination.

Now we know reasons why delays occur in construction. Then the question is, how do we solve this issue?

Keep on following this blog for the next posting. Thank you and have your nice day.

Project Quality Plan (PQP)

10. Construction work method statement
Any work method statement for the construction of any structure shall be inserted under this section.

QUALITY CONTROL IN CONSTRUCTION WORKS

A successful construction is a completed project that being delivered to client by contractor which fulfil the contract specification and requirement, the stipulated time frame given as per contract, economic and of course meet the contractor profit margin.

The key to the successful project is lies in the ability of all parties to execute a good project management which requires all parties to have a practical and effective project organisation, effective project planning and tracking, effective procurement team, effective physical construction team and effective quality control team.

As the subject of this article, "Quality control in construction work", there is a few area  that need to be emphasised in order to assure all parties that the quality management is practical and effective. To begin with this quality control, it is always being a good practice to set-up a quality control organisation which need to be documented and understood by all all relevant personnel. in other words, the "Project quality plan".

All thing that required in order to have a good and well plan quality control shall be documented and compile in a manual name as "project quality plan". Among those items are namely as the following list.

1. Project brief,
2. Project locality and site utilisation plan,
3. Work program
4. Quality control Organisation Chart
5. Job Description
6. Inspection and test plan
7. Procedure and method of Inspection and testing
8. Quality assurance and quality control forms
9. Construction method statement

However the content of the "Project Quality Plan" is not limited to those listed items. The "Quality Control" in principal is divided into three stages that is planning stage, Executions and monitoring and the last stage is to analysed the outcome of the plan to ensure the effectiveness.  

Document control in construction management

Document control is part and parcel of the important area for construction personnel to look into. The important of this are to help every party involved in a particular construction work get the right information at the right time and it help protecting interest of every party.

Due to the heavy work load personnel tend to be distracted from performing a proper document control. For example, there is important documentation that already being distributed to respective personnel, however the sender had overlook on the acknowledge receipt of the document. Thus if there will be an issue arise mentioned that the document was not received or the sender have not do the submission yet, then the sender will having problem to proof that he actually had distribute that particular document.

Looking at the scenario above, this can indirectly affecting the smooth progress of the project. The document might be needed for the purposed of material approval, notice, application of extension of time or progress claim or design change. When this issue of document control become so critical it will start affecting the completion of the construction work. Some of the issue might have to be solved at arbitration level.

For the sake of a well manage construction works and meeting the goal of any construction project, document control should not be taken lightly. I have to be part of the construction procedure. Regardless how it supposed to be carried out, whether by incorporate any document control software or conventional method, Document Control Have To Be Executed in such a manner which will have a positive impact on the project or construction works.

construction cost estimation : Flexible pavement

Cost estimation for construction of flexible pavement is very important to enable a smooth construction activities in road constructions. In order to do cost estimation of Flexible pavement for road, there are numbers of important information that we need to know about the flexible pavement. Below are some of the important parameter required to enable the cost estimation.

 

1. Flexible pavement structure, dimension and quantity.

2. Construction material required

3. Construction Methodology or work method statement

4. Construction work duration

Construction Material for flexible pavement.

1. Suitable soil (well compacted) for sub-grade
2. Down Crusher Run ( Crush and well Graded Granite stone) for Flexible pavement Sub-base and base course
3. Prime Coat
4. Asphaltic concrete Binder Course (ACB)
5. Tack coat
6. Asphaltic Concrete Wearing Course (ACW)





Estimating construction rate per unit of work

Competitive tendered price is one of the greatest factor to win a construction project. However in any business, one of the main factor is to make money. This is true and also applied to construction industry. Therefore winning a project is just a small portion of construction business but be able to secure and deliver projects within the budget is the main agenda of construction business.


HOW TO ACCOMPLISHED THAT TARGET???????


The answer is knowing how to estimate and doing the breakdown of the BUILT-UP RATE PER UNIT OF WORK.


Building the rate is in theoretically knowing the cost of every single item or component that involved in order to deliver the end product. In general these are some of the item that need to be include while estimating rate per unit work or product.


(1). Cost of the construction material
(2). Cost of the Logistic or transportation
(3). Labor cost
(4). Machinery cost
(5). Allow cost for wastage of material
(6). PROFIT MARGIN


Each of the item, from item no. (1) to item no. (5) need some simple calculation and have to be present into "per unit rate". It is then sum-up to create the cost of construction of a unit product.The next procedure is to apply item no.(6) into the sum-up cost.


For example if the cost of construction of a unit product is "W" and targeted profit margin is "Y%", the profit will be "W" X "Y%". let say that the outcome of this calculation is "Z". Hence the built-Up rate is the sum of "W" + "Z"


Calculation:
Item (1) + (2) + (3) + (4) + (5) = W
Profit Margin = Y %
Profit = W x Y% =  Z
Built-Up rate per unit product = W + Z


Built-up rate offered MUST inclusive of PROFIT and Construction Cost.

Traffic Management in road construction

Traffic management is part and partial of road construction that must be look into. Even though it do not contribute to any of the road construction it self but it does  affect the progress of the work. Traffic management become very significant if the construction site is within the existing road. As we all know existing road is road that already open to public.Thus there will be moving vehicle every now and then. We certainly do not want to see any accident occur during construction period which involve our site. Therefore a safe and practical traffic management plan must be in place.

Some of the normal measures and tools that we applied during construction work are:-

1. Provide flagmen at both end of our construction site and equip them with and Personal Protective equipment and communication tools, such as walkie talkie to enable the to guide the existing traffic efficiently.

2. Erecting some warning sign along the existing road to inform public in advance before they reach the construction area.

3. Provide detour sign if the existing traffic need to be redirect into our temporary road.

4. Erect safety barrier along the construction site to prevent existing traffic entry into our work place

5. Install "blinker" before and along the construction site to provide warning sign that public user of the existing road is approaching construction site or they are driving just adjacent to the construction site.

6. Publish construction work notice on newspapers or main stream media to alert public or road user on the coming or ongoing construction work along the road.

7. Periodic monitoring and maintain all safety and warning sign that had been installed to ensure that it is in good and practical condition.

All of the above but not limited to the listed planed safety measures in this article shall follow the minimum standard of traffic management plan required by the authority.

Traffic Management can save life, time and money.

7 important factor affecting Roadworks cost estimation

7 important item that must be consider while doing cost estimation for road construction.

1. Cost of the construction material needed to construct a road.
2. Delivery cost for the construction material.
3. Machinery and labour cost involve during construction period.
4. material wastage, labour and machine inefficiency during construction. 
5. Increase of the price of construction material, Labour and machine in the near future.
6. indirect cost such as Insurance premium, material handling cost, safety and others.
7. profit margin.

WORK PROGRAM AND THE S CURVE

Every construction project will need a well documented WORK PROGRAM or Work schedule. It is as a guide for the construction players on When and how can they achieve the target Completion date. For Planners they are well verse with Work Program. There is lots of computer aided program that can be utilised to enable them to come out with a professional look of a work program. Some of the computer aided program are, Microsoft Project, Primavera, Esteem and may more. The most common are Primavera and Microsoft Project. For a small scale project, work program even can be produce by using Microsoft excel or Office.org.

Most of the work program software are designed in such a way that it can also produce the "S-CURVE"."S-Curve" is a graphical presentation which showing informations such as "Schedule S-Curve", "Actual S-Curve", dates, Percentage of work and may more. Normally this is a method that commonly used to show the overall progress of a project. On the S-Curve graph, we will see what is the value (either in terms of dollar and cents or percentage) of previous work achieve, target value, and progress on the month of reporting.

S-Curve and Work program are both related. Changes to Work Program might affect the S-Curve. S-Curve in actual fact is derive from the work program it self. Without work program, people can still produce S-Curve but the question is, is it tally with what we planned to do?

To those who are new on the planning work, Work Program, once it being amended, it might affecting informations which you want to show on your S-curve.

Usage of Request for information

What is Request for Information (RFI) in construction work? In construction works Request for information is a method that normally being applied at construction site to obtained certain information with regards to works issues. It is ranging from the construction drawings, site condition and may others site matters. Site Manager, Site supervisor, site engineer or any site technical assistant are among the common personnel that have been using the "Request For Information (RFI)" method or form as a way of communication to officially obtained any information which will affecting the construction works.

                                                              

This RFI is commonly being issued out by contractor to the consultant or client site representative once there is any doubts arise from unclear instruction, specifications, drawings or plans or even the locality of the proposed structure. When contractor write and issue out a  "Request for information", in actual fact, they already put it on record that they are having an construction related issue which might hindered them from starting the construction for certain work or structure. As such it is a proof that they already highlighting something which might cause delay in construction progress, extra  construction cost, safety issue, site conditions or it might be only a request to confirm the validity of a verbal instruction, construction drawings or plans that had given to them unofficially. 

                                                             

Client site representative shall not take the "request for information" lightly since it having its legal value. In some cases, client site representative might not be in the position to provide such information to the contractor site personnel. If such situation occurred, with the issuance of "request for information" by contractor site representative, they then can convey or redirect the matter to their respective department or person in-charge to get the valid response or answer.

In construction, the line of communication when using the "Request for information" is between contractor site personnel and client site representative. By looking to those two parties we can say that the usage of "Request for information" Form is mostly at construction site level. 

If we notice in the above paragraph, the words "mostly" was used, this is merely because "Request for Information" also sometimes being used between headquarters and site as an internal communication in the same organisation. However the usage of "Request for information is not limited only to those application but it can be customised to suit the needs of an organisation.

Construction project stages

Construction is not about physically constructing a structure only but lot of other things involve. Construction in-whole are involving a few stages. Those stages start with setting goal by the owner (consultant/contractor's client) then followed by designing stage. Once the designers completed their design, they must first get approval from the client prior to the call for tender. Designer have to get their design as closed as they can as what had been describe by their client. This is important as to minimised any interruption during construction period due to design change. It is also important for the client in order not to burst their allocated budget for the whole project.

Upon approval of their design then consultants can proceed with the tender stage. This can be done via open tender such as through media advertisement. However some might one to call for invited tender. Invited tender is a bidding process where consultant will look for list of trusted, well reputable and competent contractor to submit their tender price for the purposed construction work.

After submission tender price, together with the client consultant, have to evaluate and come to a conclusion to whom must they award the contract. Another important part of this process is to counter check if client budget is enough. If the price they get burst their budget, the client might want to reduce the scope of work or call for another round of tender. Usually this is termed as re-tender process.

                                                    

Next before the construction can really start, upon deciding who is the contractor that can do the construction work, client will send an official "Letter of Intent" or most of the time, Client will  issue "Letter of Acceptance" or "Letter of Award". Once the official letter was sent out to the winner of the tender, consultant then need to prepare the contract document for both parties to sign.

Right after the signing process, by procedure wise, only then the awarded contractor can proceed with their physical construction work. While dealing with the construction of the structure, it is vital for every parties to keep their record of everything or important event as accurate, complete and safe as they can. This is because  those entire documents might have legal value in it. Among the records are letter of Award, Construction site diary, construction test and inspection approval, design change record, instruction from the client, records of construction meetings (site meeting, technical meeting and others important meeting or discussion) and may more.

Another important document that have to be kept properly and can be access by all parties involve is the "Master Work Program". This will show, when contractor going to start a certain work and when will they finished. Other than that, by having this master work program, client, consultant and contractor can monitor their construction health. Construction health is whether the construction work is ahead of schedule, on time or delayed. If the progress of the construction work shows delay, this is where all parties need to know why, and how to speed-up the progress or client might need to revised the construction completion date by granting Extension of Time base on valid reason as mentioned in the contract to the contractor. However if the records shows that reasons behind the delay is due to contractor negligence, client can by virtue of the signed contract and by any applicable law, penalised the contractor. Commonly happened is contractor being slap with the "Liquidated and Ascertained Damages (L&AD)" as allow in the contract.

                                                             

Upon completion of all of the construction scope of work and if the client satisfied with the end product, Client then will issue a letter of completion to contractor. This letter normally termed as "Certificate of Practical completion (CPC)". As mentioned earlier, "construction in whole involving a few stages", then bare in-mind, the issuance of CPC does not meant that the whole construction is over. Upon issuance of the CPC, another stage that will follow is the "post-construction" stage. This is a stage where all constructed structure being put into real test. The in-operation of the structure and all other components reassemble a complete structure will reveal all defects to the structure have. Defects in construction simply mean works that is done but does not functioning well. When this happened, client together with their consultant need to identify if is a defect due to contractor works or not. If it the answer is "yes", then client can request the contractor to rectify the defects as long as the defect occurred within the defect liability period. Inspection on the defect must be performed in the present of client, consultant and contractor and list of defects must be served officially to the contractor.

When the defect liability period is over, client has to close the construction account which normally termed as "closing of project account". In this stage client will released whatever money due to their contractor and consultants or recouped back whatever amount due to them from the contractor or consultants.

The next and final stage of the whole construction project is the post mortem by client them self. By performing this stage, client can evaluate, in overall, the cost, the construction period, functionality of the project and whether or not the project achieved their earlier goal. The result of the post-mortem will provide a better understanding and can be incorporated into the new project that they wish or planned to do.

Construction and global warming

Construction is one of the industries that contribute to global warming. Why is so? . Let we take a look into what is global warming.

Global warming in actual fact is due to green house effect. Green house effect happened because there increased in greenhouse gases(GHG) concentration in our atmosphere. Some of the green house gases are Carbon dioxide (CO2), Nitrous oxide or Nitrogen dioxide (NO2), Chlorofluorocarbon (CFC), Ozone(O3), Methane(CH4) and other harmful gases which have a capability to trap heat from being radiated out from our atmosphere. Some of this green house gases have the ability to exist in our atmosphere more that 100 years.

So how does our construction industries become one of the contributor to this global issue? Before we answer this question, it is best to know activities that produce these greenhouse gases(GHG). CO2 usually being produce as one of the end product from the burning of fossil fuel, where as CFC or to be more accurate Tetrachloroethene is widely used as dry cleaning agent. May be some of the cleaning agent that we used contained CFC and we applied it in our construction method.

Another cause for the increase of CO2 in our atmosphere is deforestation. As we know,  plant need CO2 to enable them to generate their food. Hence by reducing the number of plants through deforestation activities will reduce the process of carbon sink. Construction industries especially the development of area for habitation involved land clearing(Deforestation) in a big scale.

Know, how do we relate this global warming issue with our construction industries? First what are some of the activities that contribute to the GHG? As mention earlier, Burning of fossil fuels and deforestation playing a significant role in increasing the CO2 concentration in our atmosphere. Years ago,  before laws and regulation was implemented due to the alarming issue of this global warming, Construction industries tend to cleared their debris by method of open burning. It might be the cheapest solution to cleared up all the debris compare to utilised the service from any waste treatment agency which having expertise in dealing with the controlled burning technology. However method of uncontrolled open burning can cause even more CO2 being released into our atmosphere. Therefore in construction industries this method must not being used as a way of debris disposal. Further to this, the other impact to the owner of the construction project is being at risk of being penalised for the breach of laws and regulation.

Construction project manager roles and responsibility

Construction work, regardless any type of construction, a contractor will always need a competent Project manager. A person  that had been engaged to become a project manager must be able to handle these scope of work.

1. Dealing with, client, consultants, local authority, supplier, sub contractor and local residence.
2. Preparing a master work program
3. keep and maintained all of important activities through the project.
4. Attend any meetings that required his input. eg. Site meeting, Claim meeting, coordination meeting.
5. Monitoring the overall progress to ensure timely completion of a project.
6. Prepare weekly and monthly report.
7. Monitoring and ensure that the construction work meet all the Quality requirement.
8. Ensure that the end product is as per construction drawing.
9. Dealt with any design change.
10. Ensure that accommodation, transport and site office for client and consultant is always well equipped and maintained
11. Assessing the value of the work done and submit the progress claim.
12. Preparing application of Extension of time if any is required.
13. Dealt with any matter arise with regards to the construction work.
14. Dealt with any requirement and  documentation for the purpose of closing the project upon completion. 

In the event that there is any dispute, A Project Manager need to know what is in the contract, what can and what are allowed. Some of the construction work ended up in arbitration or in court, then the knowledge of contract act and tort law might be helpful.

CONSTRUCTION METHOD STATEMENT FOR BRICKWALL

Construction of brickwall seems to be an easy component of construction work. However as usual any construction work shall come with their construction method statement. Below is a general method statement for construction of brickwall.

METHOD STATEMENT FOR CONSTRUCTION OF BRICKWALL.

Construction material.

Red clay brick, Exmet, Sand, Ordinary Portland Cement(OPC), Clean Water

Construction Tools and Equipment.

Scalfolding, Brick cutter, Trowel, spirit level, Guiding tread, Plumbob, Hammer, Hand drill and etc.

Personal Protective Equipment, Safety Tape, Rubbish Chute, Safety Baricade, Safety Railing any practical safety equipment for the purpose of the construction of brickwall.

Construction Procedure.

1. Obtain approval for construction material.

2. Upon approval, Setting out of the wall location shall be done, inspect and approved prior to construction work.

3. Safety and health shall be submitted and approved by Superintending Officer(S.O) or his representative(S.O.R).

4. Submit request for start work to S.O, once steps above already complied.

Construction work.

1. Ensure that the working environment is safe and bricklayer is wearing PPE.

2. make sure that the guiding tread or line is visible.

3. lay a layer of damp proof sheet at the bottom of the first layer of the brick.

4. On top of the damp proof sheet spread a layer of mortar. The mortar shall be mix by hand or mixer and the composition is according to requirement specified in the construction drawing or contract specification.

5. Red brick then shall be lay according to the construction drawing position. 

6. Exmet reinforcement shall be introduce after forth course of the brick. If required a dowel bar shall be install to strengthen the ties between column and the brickwall.

7. At any time during the work, all debris shall be clean especially the excess mortar to avoid it from harden on the floor surface.

8. Upon completion of the brickwall, leave it to dry and bonded before proceed with the plastering work.

9. Upon completion a request for inspection shall be submitted to S.O or S.O.R for acceptance of the work.

Red clay masonry works

Building work consist of numbers of major work component. Four(4)  major components of building work are Structure work, Architectural Work, Mechanical Work and Electrical Work.

In this article we will discuss on building the building wall which is another small component of work which fall under Architectural work. Building Wall can be describe as External wall and Internal wall. Both of this wall can be build using various building material. Among the material used is Red clay brick. Building wall that was constructed with Red Clay brick, commonly known as common brick is a type of wall that being design not to carry any loading apart of its own weight.

What is common brick? Definition of common brick is " acceptable burned clay brick for the purpose of general usage of brickwork with no special claim for attractive value". Walls built with common brick required rendering or plastering for a fine finishing prior to any painting work or introducing of wall paper. Wall that required tiling as it finish surface usually required plastering to ensure that the built wall have a flushing surface in order to properly fixed the tiles.

*Standard size for masonry or Red clay Brick according to BS: 3921: 1985 or MS 7.6 : 1972 are as follows;

Length = 215 + 3 mm

Width  = 102.5 + 1.875 mm

Height = 65 + 1.875 mm

(* quoted from http://www.claybricks.com/more_info/brick-specifications.html )

In building a brick wall for any building we often heard of this terminology.

1. Half brick thick wall

2. One brick thick wall

3. One and a half brick thick wall.

All of those terminology is base on the measurement or the length of a standard brick. 

- Half brick thick wall = 1/2 x length of the brick,

- One brick thick wall = 1 x length of brick 

- One and a half brick thick wall = 1 length + 1/2 x brick length. 

Apart form the thickness of the wall another important part of the brick wall construction is the bond type between the brick. This bonding is to provide integrity between each of single piece of Red clay brick. Some of the type of bond are;

1. Stretcher Bond.

2. English bond

The application of those type of bond can be seen base on the wall thickness requirement. 

Half brick thick wall : stretcher bond

One brick thick wall : English bond

One and half brick thick wall : English bond and Stretcher bond.

Setting out for building wall construction.

Building wall construction required bricklayer to do a simple setting Out. How to do this setting out?

Below are steps that needed.

1. Study the Architectural construction drawing.

2. Do the measurement as specified on the drawing and mark every single point  (Both Upper and Lower Point).

3. On the lower ground Mark Continuous line from one end (earlier mark done at step 2) of the proposed wall to the other end of Proposed wall (earlier mark done at step 2).

4. By using Plumbob, Hang two (2) vertical tread for each end of the proposed wall. Make sure the tip of plumbob hang straight on top of the lower mark which is on the ground floor or lower floor where the proposed wall going to be build.

5. Tie a horizontal tread on both vertical tread. make sure that this horizontal tread is moveable and not too loose until it cannot stay on position when it is moved up and down to a new desire possition along the vertical tread.

4. Start lay your wall when all of this guide line/tread is fixed and practically working.

The tread is useful to ensure that the wall is build with a vertically Straight and horizontally straight unless the wall is designed to certain pattern.

When doing Setting out for a wall you will need this basic hand tool and consumable Material

a) Hammer 

b) Tread

c) Measuring Tape

4) Maker ( Pencil / Pen )

5) Nail

6) Chalk liner

 7) Plumbob.

Construction and OpenOfice Free software.

Today reality, everyone are keen to keep the cost as minimum as it can be. The idea by doing so is, increasing profit from their operation. What does this mean to us as person involve in construction? It simply meant that if I can reduce my cost in delivering my contract successfully, I will be competitive enough to secure more project. As a result, there will be increase in Income. However in construction it is not only about the efficiency in physical construction but also the indirect supporting tools that we use.

Why OpenOffice? OpenOffice is an computer software which functioning as Microsoft office product. It have different type of software such as OpenOffice Calc which do the similar work like excel, OpenOffice writer can serve the purpose of the MS word and OpenOffice impress can do the same presentation like MS Powerpoint.

What so special about Openoffice? Its free to download and use. With this condition, we don't have to spend much money to purchase the software.

Wait. However there is some limitation in using this OpenOffice. You might facing problem with those who does not use OpenOffice especially if you want to share or distribute digital soft-copy of your works. before you share you works save the file as excel file to enable those that are using MS excel be able to open the file and edit it if necessary.

Best of all to those construction that want to minimized the cost on the the computer aided software. It might not be significant. but the bottom line is cost saving.(if possible)

Construction manager delegation of power

cConstruction manager or project manager is an important element for any construction field. Thus, it is important for them to be available at all time during construction period. However in real life, everybody need sometime to rest or leave for what ever reason. In view of this situation, it is always a good practice to perform "power delegation" procedure. This is a procedure to authorised a competent personnel to take over the manager duty when ever he or she will be on leave for a substantial period of time such as one week. Most of the construction company only make known the delegation of power to the person affected but in most cases they fail to notify other organisation on the issue. This scenario seems to be only a minor matter any it would not affect the construction work but it do affect the works if drastic or urgent decision is required in which the decision only can be make by authorised personnel. Hence any delegation of power shall be make official and all organisation that involved shall be officially inform.

The content of the delegation of power shall clearly stated the name of the person that will take over the responsibility, his scope of work and his limit of authority. If required may be the period he or she be in power also shall be stated.
