The basic question: can this contractor finish the work?
The surety assesses whether the contractor has the character, experience, people, equipment and systems to perform the type and size of work requested. A successful history on similar projects, reliable references, sound estimating and job-cost controls, and a record of paying subcontractors and suppliers on time can all matter.
核心問題：這家承包商能否完成工程？
保證公司會評估承包商是否具備完成相關工程類型及規模所需的信譽、經驗、人員、設備和管理系統。類似工程的成功往績、可靠推薦、健全的估價及工程成本控制，以及準時支付分包商和供應商的記錄，都可能非常重要。
Financial strength is more than cash in the bank
Underwriters commonly review working capital, net worth, profitability, cash flow, debt, accounts receivable and payable, bank support and the contractor’s overall backlog. Cash is helpful, but cash alone does not prove that a contractor can manage a larger bonded work program. The surety wants to see enough financial capacity to absorb delays, cost overruns and other project pressures.
財務實力不只是銀行現金
核保人通常會審查營運資金、資產淨值、盈利能力、現金流、債務、應收及應付帳款、銀行支持，以及承包商的整體在手工程。現金固然有幫助，但單靠現金並不能證明承包商有能力管理較大的保證工程量。保證公司希望看到企業有足夠財務承受能力，以應付延誤、成本超支及其他項目壓力。
The documents commonly requested
A contractor may be asked for several years of accountant-prepared year-end financial statements, current interim statements, aged receivable and payable lists, bank and credit-line information, an organization chart and key-person resumes, corporate ownership details, project references, a list of major completed jobs, and a schedule of work in progress. Requirements vary by surety and program size.
通常需要準備的文件
承包商可能需要提供數年的會計師編製年結財務報表、最新中期報表、應收及應付帳款帳齡表、銀行及信貸額度資料、組織架構圖、主要管理人員履歷、公司股權資料、項目推薦資料、主要完工工程清單，以及在建工程表。實際要求會因保證公司及所需額度而異。
Why the work-in-progress schedule matters
The work-in-progress schedule helps the surety understand every current job: contract value and change orders, billings, costs incurred, estimated cost to complete, expected gross profit and completion date. It can reveal whether projects are performing as estimated and whether the contractor is taking on more work than its people and finances can support.
為何在建工程表十分重要
在建工程表協助保證公司了解每個現有項目，包括合同金額及變更工程、已開票金額、已發生成本、預計完工成本、預計毛利及完工日期。它可以顯示工程表現是否符合原先估算，以及承包商是否承接了超出人力及財務承受能力的工程量。
There is no universal approval formula
Each surety applies its own underwriting standards. A program may set a maximum single-job size, total aggregate backlog, approved types of work, geographic area, financial conditions and indemnity requirements. Strong information does not guarantee approval, and a project may still be declined because of its contract terms, size, duration or risk profile.
不存在通用的批准公式
每家保證公司都有自己的核保標準。保證額度可能規定單一工程上限、整體在手工程上限、可接受工程類型、地區範圍、財務條件及彌償要求。即使資料良好，也不保證一定獲批；個別工程仍可能因合同條款、規模、工期或風險特徵而被拒絕。
