DeAngelis Diamond is a renowned national construction management firm, founded in 1996 by industry veterans David Diamond and John DeAngelis. With a commitment to excellence and a mission grounded in seven core values—Faith in God, Honor to Build, Lasting Relationships, Excellence & Quality, Leadership, Healthy Environment, Culture, and Integrity—DeAngelis Diamond has established a reputation for delivering high-quality construction services across various sectors.

Since its inception, the company has successfully negotiated and managed over $5 billion in construction projects, showcasing its extensive capabilities in a diverse range of building types. These include Automotive, Educational, Faith-Based, Financial, Government, Healthcare, Hospitality, Industrial, Multi-Family Residential, Office, Retail, Science & Technology, Senior Living, and Green Building. This broad spectrum highlights the firm’s versatility and proficiency in addressing the unique requirements of each market segment.

DeAngelis Diamond specializes in several key services, including Pre-Construction, Design-Build, Construction Management, General Contracting, and Program Management. The firm caters primarily to clients in the commercial construction sector, focusing on providing tailored solutions that meet the specific needs of each project. Their comprehensive approach not only emphasizes quality craftsmanship but also incorporates critical elements such as sustainability and environmental stewardship throughout the construction process.

The company's ethos revolves around a collaborative spirit, aiming to foster innovation while maintaining a sharp focus on safety and quality. DeAngelis Diamond is also proactive in implementing green initiatives, ensuring that every project contributes positively to the environment and community. This dedication to excellence and social responsibility sets DeAngelis Diamond apart in the competitive construction landscape and reinforces its status as a trusted partner in the industry.

Need to submit a Pay App to DeAngelis Diamond?

Payment applications generally include the application for payment form and a continuation sheet (which includes a schedule of values and change orders). Depending on the situation, you may also include backup documents like materials receipts and invoices, payroll wage reports, and lien waivers.

It's a lot to keep straight, and it's further complicated by most GCs requiring their own custom payment application forms, rather than standard AIA templates. Fortunately, Siteline has more than 8,000 forms from over 6,000 GCs—in our system. Our software streamlines the entire monthly billing workflow, ensuring you submit the perfect pay apps on time, every time, which gets your invoices paid about three weeks faster.Want to see for yourself?
