本書について
本書は、国際建設プロジェクトにおいて、請負者の現場契約管理の一業務として、発注者側（主にエンジニアなどの現場監理者）などに宛てるレターを対象として、実際の事例を元にしたものを収録しています。それらのレターには、日報・月報などの日常業務の報告書や工程表・施工計画書・請求書などの定型的なものから、想定外の諸問題についての通知、設計変更、クレームに至るまでさまざまな形態が含まれます。いずれにせよ実際のレター作成にあたっては実状に即した十分な勘案が必要となりますので、本書はあくまでも参考としてご利用ください。
また、レター作成にあたっては目的に応じた適切な表現とすることが大切であり、そのために文章を書く上での基本を守っていくことは重要です。序章では、この観点から注意すべき点や参考としてほしい点などをかいつまんで挙げています。ただしレター表現は場面、立場、慣習などに応じた判断を常に伴うものであり、その表現には幅があると言えますので、種々の書き方の参考書や情報を参考にして応用してく
ださい。

E-6 発注者支給鉄筋の早急な搬入を督促する
発注者： 公共機関

工事種別： 土木（ダム）宛先： 発注者

契約形態： 施工

契約約款： ――

国／地域： マレーシア

要旨: 先に通知したように、発注者支給の鉄筋のうち特に T22 鉄筋の搬入遅れが工程上で重大な支障を来しており、期日までに必要量が届かなければ工事は一時中断とならざるを得ない。他の部位で実施できた別の鉄筋での代用策は取れない重要な部位のため、早急に搬入することを要求する。

Re: Delay in Delivery of Steel Bars
Dear Sirs,
We refer to1 our letter Ref. no.___ dated _____ in which we informed you that our Contract
Schedule is being affected by delay in delivery of steel bars directly purchased by the
Employer as specified in the Contract. The shortage of T22 bars has become the major delay
issue in our construction programme.
The construction of the Hot Well Foundations and Mill Foundations has been given priority.
We are currently in a position where we may have to implement2 a double-shift programme
in order to maintain progress. We require 210 tons and 100 tons of T22 bars in the Hot Well
Foundations and Mill Foundations respectively3. These quantities are required by mid
November of this year; failure to obtain the necessary steel bars may result in our labor andplant standing idle. Therefore, this material shortage will inevitably have a serious impact4
on our construction work progress.
At the site meeting this morning, you raised a proposal to use T20 bars for the said
Foundations with altered spacing in place of T22 bars in the same way that we haveexecuted in other structures such as ＿＿＿＿＿ in accordance with your instruction.
However, we found that due to the restricted steel bars arrangement required in the said two
essential Structures, it is impossible to substitute5 T20 bars for T22 bars.
We sincerely request that you expedite delivery of the said steel bars as a high priority.
Yours faithfully,

K-8 現場条件の違いに対するコスト調整と工期延長を求める
発注者： 公共機関

工事種別： 土木（鉄道）

契約形態： 施工

宛先： 契約担当官
契約約款： FAR 約款

国／地域： 米国

要旨: トンネル工事で（予想外の）異なった地盤条件に遭遇し（薬液注入などの）追加の対応をおこなったことに対する追加費用および工期延長をクレームする。

Re: Claim on Differing Site Conditions at ［location］
Gentlemen:
We hereby claim an equitable1 cost adjustment and a time extension due to the differingsite conditions2 (DSCs) in accordance with Supplemental General Conditions.
The additional cost incurred due to the DSCs is based upon the differential between theregular mining cost (the cost if the DSCs did not occur) and the actual cost incurred whilst
working under the DSCs. The extra cost is itemized in the following manner:
1.

Extra mining labor cost (Actual Labor Cost vs. Regular Labor Cost based on average
production ___ Rings/day),
2. Labor Cost and Material Cost to fill out void, and
3. Subcontract Cost for drilling extra holes to fill out void.

Please refer to the attached document and recapitulation3 sheet.
The DSCs also caused two types of delay to the Contract Time. The first was the tunnel
mining delay and the second was the delay resulting from installing the belt conveyor
system. If there had been no DSCs, the belt conveyor would have been operational for ____
days instead of ___days. Based on the daily tunnel mining progress attached, the impact ofthe mining delay was ___ days and the impact of belt conveyer system delay was ___ days.
We hereby claim that the Contract Time be extended for ____days and the additional cost as
a direct consequence4 of the above as per attached sheets.
Should you have any queries concerning the above, please contact us.
Very truly yours,
