Project Behind Schedule

In construction Industry, it is very often that we heard the term "project is behind schedule". What does it meant with this term. Project Behind Schedule is when the achieved project progress percentage is less than the planned or targeted percentage for reporting period. This normally happened due to several factors. Among them are;
1. exceptionally incremental weather (of which the weather condition is not as usual or not as previously recorded for that particular area),
2. shortage of the construction material ,
3.insufficient and inefficient of manpower and machinery,
4. cash-flow for the project,
5.instruction by the client to change design and requirement,
6.Delayed in approval (material, method and etc) by client or their representative,
7.legal issue and many other reasons.

In this situation contractor need to study why the project is behind schedule. Some of the delay might have been contributed by the act of client. and if there is any, contractor might want to consider applying for the extension of time to enable them to complete the project beyond the original contract period and also this will help contractor from being penalised due to late delivery of the project. If the extension of time is approved then the contractor have the ground to revised the work program to take into account the approved extended period. the second advantage to contractor is they have the ground to claim for loss and expense due to this event. however to lodge a claim for this is advisable that contract need to study their contract whether this is allowed in the contract.

In the occasion that the delay is due to contractor own fault, than contractor have to come out with the catch-up plan. This mean contractor might need to increase their productivity by engaging more machinery and manpower. The other option is to work around the clock to meet their deadline date.In the event the contractor cannot delivered the project on time, they are at a risk of being penalised or even being terminated from the contract.

To avoid or minimised this "project behind schedule" situation, a good project manager is the key. The project had to be well planned. All aspect need to be consider especially the cash flow, procurement of materials, manpower's, machinery's and weather conditions. With all these explanation, having a good Project Manger is crucial in ensuring project is deliver with in the contract period.

Construction Failure

I bought an apartment costing $137,980.00 in 2004 in Malaysia. However until 2011 the apartment have not being completed and handed over to me. This sound familiar to numbers of house buyer or Property purchaser. I consider this a bad investment, I wanted to dispose this property but I am Not sure whether I can gain back my capital. What I know is, certainly not, because it is uncompleted property.

The above scenario is a scenario of failing construction or to be more accurate, failure in project management by the developer. This developer fail to delivered the property in time, they failed to pay the penalty of late delivery of the purchaser. This had resulted to the purchaser file in the winding up process on this developer. Know the developer is a bankruptcy.




However, the question is, will the purchaser get their property back if the development was finance by the bank? If yes how? How about the remaining of the purchaser who do not do anything or take any legal practice on the developer? Is there anyone who know how in the case of Malaysia legal law. There are number of claimant on the property. First the financier of the development,Second the group that lodge the winding up, third, other parties that had given the financial means to help the developer run their day in day out business and the last but not least the purchaser that had not taken legal action on the developer but instead signing the deeds of settlement that allowed the developer to complete the development within 8 months from the date of signing, however until this being publish here the deed of settlement was not stamped with stamped duty.

In this scenario who's fault is this?. Is it The developer, The Consultants or the Kementerian Pembangunan Perumahan Negeri Sarawak, Malaysia and their agency( because they failed to monitor and taken positive action in preventing this issue from happening).

BROKE DOWN CONTRACTOR

Have you ever been a broke down contractor?...
What does it mean with broke down contractor? it is very common that we here that contractor complaining that they cant bring some more construction material. this is not because that they do not have even a single sen but it merely because what they have is just enough to run the company. Most of the time construction payment is base on monthly or progressive payment certified by the client or their representative. However there is cases that after the evaluation and verification process after contractor submit their claim, contractor had being paid very late. some time they only received their payment after 3 months or even more. with this view, lets we make some calculation;
lets say, contract sum = $50M
construction period = 12months
Average (prorated) spending /months = $50M/12 = $4.167M
Hence total spending for 3 months = 3 X $4.167M =$12.5M
let say, Evaluation on work done take 2 weeks after progress claim submission.
therefore spending for 2 weeks =( $4.167/4weeks) X 2 weeks = $2.08M
The total spending from the date contractor submit their claim until they received their payment
will be;
=3 months spending + 2weeks spending = $12.5M + $2.08M = $ 14.58M
With that you have to fork out $14.58M!!!!!!!! its is a big sum of money.
Looking at this scenario, It is very important that a proper financial planning being carried out for every construction project.
This scenario is only for one project. what if you have 2 or even more project in hand !! It can be a deadly disaster...
Looking into this situation, if contractor is now well prepared with the financial planning when they are participating in a quotation or tender it will be a trap for your self...you will be one of the broke down contractor or even a bankruptcy!!!!!!!!!!!!
Construction is not for those that are not prepared to be a broke down person.
