About TDX

TDX Construction is a full-service construction management firm that provides both pre-construction and construction phase services. For most projects, TDX is brought on board early in the planning and design phase to develop preliminary cost estimates and schedules and to review proposed project plans for feasibility. During project design, TDX reviews and comments on progress drawings prepared by design consultants, conducts constructability reviews, leads value engineering efforts, recommends cost saving measures, and prepares independent cost estimates to verify design consultants' estimates. TDX also reviews the feasibility of LEED credits proposed by the design. TDX prepares and regularly updates a comprehensive CPM schedule covering all design and construction tasks and manages pre-construction and construction activities in line with the schedule. Finally, TDX prepares bid packages, manages the solicitation and review of bids and assists owners in making contract awards.

During construction, TDX manages all aspects of projects including: coordination of trades; quality control; safety management; shop drawing/submittal review; payment processing; change order management; CPM scheduling; testing and inspection; maintenance of project records; management of construction related LEED activities and documentation of LEED credits; general project administration; and project closeout and turnover.

These services are carried out by TDX's in-house staff that includes cost estimators, schedulers, licensed engineers and architects, project controls personnel, contract specialists, accountants, and field personnel experienced in inspection, safety, and all aspects of construction project management.

TDX is an active participant in all pre-construction phase design and coordination meetings. We provide early input regarding bidding, scheduling, material availability, constructability, cost effectiveness and feasibility wherever needed to advance the team effort. TDX's pre-construction effort is lead by a firm principal and utilizes the services of our in-house cost estimating, scheduling and document review staff. Our pre-construction services include the following:

Project Schedule Development

Prepared for each project identifying design activities, construction packages and related activities for each of the team members including the Architect, Owner and Construction Manager. Each activity is assigned restraints and the precedence of related activities is established in a graphic form. Milestones with completion dates for critical activities are identified and liquidated damages may be assigned to emphasize the importance of their timely completion. Durations for each activity are agreed upon with appropriate team members.

Schedule Updates

Prepared on a monthly or bi-weekly basis highlighting bottlenecks and identifying team members responsible for the delay.

Cost Estimates

Prepared in CSI and/or system format at the end of each design phase and reconciled with estimates provided by the Architect. Our unit prices are current and based on the latest market feedback from our construction management and general construction work.

Value Management Program

TDX identifies and evaluates alternates, not only from a cost point of view, but also for ease of constructability, maintenance, efficiency, reliability and compatibility with the other systems and makes recommendations to the Architect and Owner.

Trade Payment Breakdown Formats

Prepared for each contractor based on the final estimates and incorporated in the General Requirements section of the Contract Documents.

Document Reviews

Conducted throughout the design process, reviewing documents for construction detailing, coordination and constructability, identification of duplications and gaps in the scopes of work among the documents for various construction disciplines. We also identify items that could result in future change orders or claims or in labor disputes and conflicts among trades. All comments are shared with the design consultants and the Owner.


Comprehensive Bid Packages

Early in design, a preliminary list of bid packages is established. As the design phase progresses, bid packaging recommendations are refined to maximize competition in the current market, maximize M/WBE participation and secure the best pricing for the project. Detailed project requirements for individual packages are established and documented in the applicable specification sections.

Comprehensive General Requirements

As designs are completed, a general requirements package is developed that includes a CPM schedule with milestones, a detailed trade payment breakdown template, Site Logistics Plan, Phasing Plan (if required) requirements for placement of applicable temporary facilities, and each contractor's responsibility with respect to debris removal and clean up, temporary services, standby (if any), appropriate allowances (if any), and barricades and protection.

Development of Bidder Interest

Prepare Bid Notices, develop lists of appropriate bidders and solicit bidders interest.

Pre-Bid Walk-Throughs

Organized at the site for prospective bidders. These meetings familiarize bidders with site conditions to facilitate their preparation of bids.

Bid Review and Analysis

Bid Tabulation Forms and a Bid Comparison Spreadsheet are developed and award recommendations are made to the Owner.

The objective of the construction management team is to provide coordination and control over all aspects of work in the field in order to result in an organized, timely, and cost effective construction effort. This includes the assurance that all of the members of the project team work in concert and carry out their responsibilities on the project.

TDX's construction management teams operate with the clear understanding that they are the representatives of the Owner in the field and are responsible to the Owner for the complete and successful management of the project. TDX provides the following construction phase services:

Trade Payment Breakdown Review

Each prime contractor submits a trade payment breakdown that is reviewed against the construction estimate to ensure that enough money is included for completion of all items and that there is no "front loading" of costs. Once approved by the Owner the trade payment breakdown is used to generate payment requisitions.

Comprehensive Construction Schedule

In meetings with each contractor, time frames for critical activities and lead times for manufactured items are verified, and the logical sequence of work and interrelation of activities is reviewed. After receiving further comments from the contractors and project team, the updated schedule is issued to the contractors as the official project schedule and is the document used for monitoring the progress of the project.

Schedule Management

To ensure adherence to the official project schedule, TDX reviews the status of ongoing work activities, ascertaining the requirements for remaining work, and tracking the status of long lead items. Once long lead items have been identified and highlighted on the CPM schedule, the associated procurement, buyout, shop drawing submittal, and fabrication dates can be calculated, monitored and expedited as needed. The completion of milestone work activities is also monitored with emphasis on activities that are interdependent among the various trades. If slippage occurs in either a long lead item or critical work activity, contractors are directed to take appropriate action.

Construction Supervision

Provision of field superintendents in all construction disciplines to conduct quality review and inspection of work installed by contractors.

Comprehensive Safety Plans

Approval and monitoring of the implementation of contractors' safety plans. Daily site inspections are conducted to assure that the requirements of the Site Logistics Plan included in the contract documents are met and that the site is kept in good order. The focus of all safety efforts is to protect the lives of the public and safeguard the Owner's property, adjacent property and the contractor's equipment and materials.

Bi-weekly Job Meetings

Conducted at the work site by TDX with all members of the project team including major contractors and subcontractors. The primary agenda items are site safety, general conditions, shop drawing submittal status, monitoring of long lead items status, scheduling of immediate and long range work activities, quality control, building department approval, utility approvals, coordination of work between prime contractors, and identification and resolution of problems. Minutes of the job meetings are prepared by TDX.

Coordination Meetings

Conducted by TDX with the mechanical, plumbing and electrical contractors to resolve conflicts and interferences, obtain sign off of all disciplines on coordination drawings, and ensure that work progresses without delay.

Monthly Core Team Meetings

Held with the Owner, Architect and TDX to bring individuals not involved daily on the site up to date on project progress and to discuss, among other issues, the status of the schedule and the budget. The CM prepares minutes of all Core Team Meetings.

Project Reporting

Preparation of daily reports on job activity and weekly reports of job progress. Provision of site photos to record work progress and monthly reports on the percentage of completion. Any deviation from contract specifications triggers an "exception report" issued to the contractor for corrective work. These reports are recorded on a deficiency log and all work is corrected before final payment is approved.

Testing and Controlled Inspection

TDX monitors the scheduling and implementation of testing and controlled inspection to ensure that it is completed on schedule and in accordance with code requirements and contract documents.

Evaluation and Processing of Change Orders

Review and determination of the validity of proposed contractor change orders, finalizing scopes of work, developing Owner's estimates for the work, conducting negotiations with the contractor and maintaining a change order log.

Contractor Payment Requests

Review and processing of payment requests and provision of a Comprehensive Monthly Financial Summary including all requisitions, payments, and approved, pending and anticipated change orders.

Contractor Claims

Claims are analyzed utilizing contract documents and project records. Recommendations are made to the Owner and negotiations are conducted with the contractor.

Project Record Keeping

Complete Project Files are maintained including Contract Documents, Correspondence, Financial Documents, Owner Requests and Authorizations, RFI Requests and Responses, Addenda, Bulletins, Reports, Meeting Minutes, Requisitions and Requests for Payment, MSDS Sheets, Record Photos. A computerized shop drawing submittal log and schedule is prepared and issued to each contractor. As submittals are received they are logged, processed and forwarded to the Architect for review and approval. Records of all submittals, samples and product data and approvals are kept in the project files for easy reference. Primavera Expedition software is utilized to maintain all project records.

Updated Contract Documents

A complete set of contract documents is updated and maintained by TDX to reflect all changes due to addenda, Architect's bulletins, program changes, or field changes. All superseded documents are kept on file for change order review and documentation. This careful recordkeeping is important to ensure the availability of documentation for claims or litigation.

Project Closeout

Separate closeout files are created for each prime contractor and a closeout list is prepared including items such as as-builts drawings, maintenance and operation manuals, punch lists, owner acceptance, building department sign-off, guarantees, payment affidavit, and the consent of surety. Prior to acceptance by the Owner, "preliminary" and "final" Punchlists are prepared by the project team. Punchlist inspections are performed for each contractor. The turn-over and commissioning of all building systems and spaces and the training and assistance of building management staff is coordinated. When the entire project team is fully satisfied with the work, a recommendation is made for final payment and close out of each contract.
