Work Completion Letter to Contractor

Dear Peterson,

This letter is regarding our existing contract with your company. On 3rd April 2019, we entered into a contract with your company ST&T Construction to complete the Kennedy Road Upgrade project.

Unfortunately, the work has been left unfinished by your team, with the roadside barriers not being cleaned and finished in accordance with the contract specifications.

We would appreciate it if you could organize your company’s resources, teams, and workers to complete the work by the deadline as specified in the contract, that is by October 5th, 2019. This is the second complaint letter that I had to send to you, as you are aware that your team was late with completing the work progress milestone in the month of July as well.

Sample Letter to Contractor to Complete Work

This type of unprofessional behavior from a company of your reputation is really unacceptable and saddening for us. You can contact me on the contact details mentioned at the end of this letter to discuss or arrange a time to talk as early as possible.

I look forward to settling this matter amicably and quickly. If, however, you choose not to undertake the rectification and finish the backlog work required by October 5th, I will be compelled to consider taking further action on this to resolve the complaint through the Department of Commerce or the Construction Disputes Tribunal.

I look forward to the timely completion of work and no further complaints from your side.

Complete Work Letter to Contractor

Respected sir,

I am writing this letter on behalf of my organization to make a reminder for you, regarding our project that we have an ongoing contract with your company dated 5th July 2018, since no work has been started yet from your side and there are no developments on the project till date. 

As per your demand, and as stated in the contract, we have paid 50% of the amount asked by you in advance which was transferred earlier than the deadline you provided, and you were supposed to start the construction of our new building in at the start of this month.

All these details are clearly stated in our contract and you are fully aware of the consequences of non-compliance in this matter. 

Now 2 weeks have passed, but you have not started the work on the site. You are supposed to finish the project by the end of September as per the contract.

Kindly start working on the project as soon as possible otherwise, we will be compelled to withdraw this project from your company and hire another construction company for this project. Thank you.

Complete Work Letter to Contractor

Dear John,

We regret to inform you that the progress of work against the ongoing construction project which our respective companies have a contract for, dated 5th August 2020, is too slow which is affecting the overall progress of the whole project and as a result, we are losing our targets. 

This was very clearly communicated to you by a previous letter from my side how important it is for our organization to finish this project by the deadline as provided in the contract, as we have an audit coming up in the very next month of your delivery date and it takes time for our team to process the outcomes forwarded by your team. I have attached a copy of that previous letter with this one. 

We do not expect such a careless attitude by a company with such a nice reputation in the market and hence it is saddening for us that it has come down to this.

It was not my only choice to send you this warning letter but if this practice continues, we will not be able to start our new project which is going to start right after the end of this project, and also the losses we will incur due to hindrance in the coming audit. It is again mentioned for your kind information that the end date of this project is October 5th, 2020 and we have to complete all exchanges before this period.

I hope you will direct this to your team and enhance the pace of work.

Thanking you,

Matt Collins

Dear Sir/Ma’am,

This is to bring in to your kind attention that the due date of the project completion which is December 16th, 2019, is arriving very swiftly. It has been noted with the great observance that there is still a huge amount of work pending with some of the leftover works too.

As per the contract between our organizations, this might lead to non-compliance, and you are aware of the clearly mentioned situations that may arise as a result of that.

It has also been noted that your team has not been working with adequate sources for some time. It is, therefore, the need of the hour that I issue this warning letter to you, so that you may increase your manpower or required resources to complete the pending work in time.

So I highly recommend and advise you to sort the mentioned issues as soon as possible to boost up the pace of work in accordance with the Contract Agreement between our respective organizations. Quick action in this regard is expected from your side.

Your company holds a great stature in the market and claims to be the best in terms of service and hence this is unacceptable for us to see such negligence and lack of professionalism from your team.

Also, we have informed you of this situation arising in the past by my previous letter dated 5th August 2019, a copy of which has been attached to this letter. Please acknowledge this letter with a timely and reasonable reply.

Looking forward to quick action.

Yours Sincerely,

Scott Peterson
